-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-GC_CLAIM
-```
-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

-GC_CLAIM
-```
-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

+Named apps have independent policy, token files, gateway connections, chat
+bindings, ingress receipts, and health counters. The default token remains at
+`secrets/bot-token.txt`; named tokens use
+`secrets/bot-token-<app>.txt`. All token files are mode `0600`.
+Named imports authenticate the supplied token with Discord and reject it before
+any local mutation unless its bot user ID matches `--application-id`. Omitted
+allowlist flags preserve an app's existing policy during credential rotation.
+An explicitly supplied empty token or token file is an error, so a failed Bao
+read cannot silently update metadata while retaining a stale credential.
+An app name is pinned to its first `application_id`; import a replacement under
+a new app name instead of changing that identity in place. Config and token
+persistence share one lock and roll back together if the credential write
+fails.
+
+Run `gc service restart discord-gateway` after adding, removing, or rotating
+named apps and credentials.
+The gateway starts one connection per configured app and staggers Discord
+identify requests. A failed named connection reconnects independently and does
+not stop the other bots.

+# Multi-App Discord Chat
+
+## Objective
+
+Allow one Gas City Discord pack instance to host multiple Discord bot
+identities. Each identity must have isolated credentials, app-aware room and
+DM bindings, an independent gateway connection, and same-app replies. Existing
+single-app cities must continue to work without configuration or command
+changes.
+
+The immediate consumer is the Gas City Inc engineering organization: a team
+city can expose its technical lead, product manager, and design partner as
+separate Discord bots in one team channel.
+
+## Supported Surface
+
+The multi-app slice covers chat transport:
+
+- app import and credential storage;
+- room and DM bindings;
+- gateway ingress and per-app policy checks;
+- explicit publish and `reply-current`;
+- per-app gateway status.
+
+Slash-command interactions, workflow channel/rig maps, room launchers, and
+command sync continue to use the legacy/default app in this slice. Named apps
+must use explicit chat bindings. This keeps the bridge small while preserving
+the existing workflow surface unchanged.
+
+## Contract
+
+### Configuration
+
+The existing `app` and top-level `policy` remain the default app. A new `apps`
+registry holds named apps. App names are stable lowercase slugs matching
+`[a-z][a-z0-9_-]{0,31}`.
+
+```json
+{
+  "app": {
+    "application_id": "1484616391729483786",
+    "public_key": "...",
+    "command_name": "gc"
+  },
+  "policy": {
+    "guild_allowlist": ["123"],
+    "channel_allowlist": ["456"],
+    "role_allowlist": []
+  },
+  "apps": {
+    "ollie": {
+      "application_id": "1526662042302287982",
+      "public_key": "...",
+      "policy": {
+        "guild_allowlist": ["123"],
+        "channel_allowlist": ["456"],
+        "role_allowlist": []
+      }
+    }
+  }
+}
+```
+
+Bindings gain an optional `app` field. Legacy bindings without it belong to
+the default app. Named bindings are keyed by app as well as conversation so
+multiple bots can bind the same Discord channel independently.
+
+```json
+{
+  "id": "room:456@app:ollie",
+  "kind": "room",
+  "conversation_id": "456",
+  "guild_id": "123",
+  "app": "ollie",
+  "session_names": ["teams.lead"]
+}
+```
+
+### Secrets
+
+- Default app token: `secrets/bot-token.txt` (unchanged).
+- Named app token: `secrets/bot-token-<app>.txt`.
+- Every token file is mode `0600` inside the mode `0700` secrets directory.
+- Tokens never appear in config, status output, logs, exceptions, or test
+  fixtures that can be committed.
+- Unknown or invalid app names fail closed before a secret path is built.
+- A named app slug is pinned to its first application ID. Replacements use a
+  new slug; only same-identity token rotation is supported.
+
+### Commands
+
+The following optional selector is additive:
+
+```text
+gc discord import-app --app <name> ...
+gc discord bind-room --app <name> ...
+gc discord bind-dm --app <name> ...
+gc discord publish --app <name> ...
+```
+
+Omitting `--app` retains the default app's command shape, configuration, and
+binding-selection behavior when an exact default binding exists. The existing
+top-level policy remains authoritative and is enforced for default-app ingress,
+bind, and publish just as an `apps.<name>.policy` is for named apps. If no
+default binding exists, one matching named binding may be resolved
+automatically; multiple named candidates are ambiguous and require `--app`.
+`reply-current` does not need an app flag for its normal path: it inherits the
+app recorded on the current ingress turn.
+
+### Gateway and routing
+
+- The existing `discord-gateway` service starts one `GatewayWorker` per
+  configured app with a token.
+- A worker receives its app name explicitly; it never infers identity from
+  mutable global config.
+- Gateway status, queues, reconnect state, and counters are isolated per app.
+  One failed connection must not stop another.
+- Ingress receipt IDs are app-scoped for named apps so an ignored copy seen by
+  one bot cannot suppress delivery by the bot that was actually mentioned.
+- Every ingress receipt stores `app`; every publish stores `app`.
+- Binding resolution and allowlist checks always receive the worker app.
+- Room bind and publish verify Discord's actual guild and parent channel rather
+  than trusting caller-supplied binding metadata. Role allowlists remain
+  inbound-user checks.
+- `reply-current` selects the token from the ingress app and rejects missing or
+  stale app references.
+- Bot-authored Discord messages remain ignored, preventing bot loops.
+
+Adding, removing, or rotating an app or credential requires
+`gc service restart discord-gateway` so the service rebuilds its worker
+registry and reconnects with the current token. `gc reload` alone does not
+restart an unchanged gateway service.
+
+## Commands for Development
+
+From the `gascity-packs` repository root:
+
+```sh
+python3 -m unittest discover -s discord/tests -p 'test_discord_*.py'
+python3 -m unittest discord.tests.test_discord_intake_common
+python3 -m unittest discord.tests.test_discord_chat_scripts
+python3 -m unittest discord.tests.test_discord_gateway_service
+```
+
+No dependency is added; implementation uses the Python standard library and
+the existing pack helpers.
+
+## Project Structure
+
+- `discord/scripts/discord_intake_common.py`: config, secret, binding, receipt,
+  publish, policy, and status contracts.
+- `discord/scripts/discord_intake_import.py`: app import CLI.
+- `discord/scripts/discord_chat_bind.py`: app-aware binding CLI.
+- `discord/scripts/discord_chat_publish.py`: explicit app selection.
+- `discord/scripts/discord_chat_reply_current.py`: ingress-app inheritance.
+- `discord/scripts/discord_gateway_service.py`: one worker per app and app-aware
+  ingress.
+- `discord/tests/`: unit and service tests beside the existing Discord suites.
+- `discord/README.md` and command help: public usage and migration guidance.
+
+## Code Style
+
+Keep app identity explicit at boundaries and preserve empty-string default app
+semantics internally:
+
+```python
+app_name = common.validate_app_name(args.app)
+binding = common.resolve_chat_binding(
+    config,
+    kind="room",
+    conversation_id=args.conversation_id,
+    app_name=app_name,
+)
+token = common.load_bot_token(app_name)
+```
+
+Do not use process-wide mutable app identity, silently fall back from an
+unknown named app to default, or catch credential/config errors and continue
+with another token.
+
+## Testing Strategy
+
+Tests are written first and must demonstrate failure on the single-app code.
+Coverage includes:
+
+1. legacy config, token path, binding IDs, status shape, and commands;
+2. normalization and validation of named apps;
+3. token isolation and file modes;
+4. two bindings for the same room under different apps;
+5. app-scoped allowlists and ingress deduplication;
+6. same-app `reply-current` and explicit publish;
+7. independent gateway ready/failure/reconnect status;
+8. unknown and ambiguous app selectors failing closed;
+9. bot-message loop prevention with multiple connected bots.
+
+The full Discord pack test suite runs after each vertical slice. Live rollout
+then verifies every configured identity with status counters and one inbound
+and outbound message in its authorized channel.
+
+## Boundaries
+
+- Always: preserve legacy behavior, validate external/config input, isolate
+  secrets, redact errors/status, and test both happy and failure paths.
+- Ask first: changing the public interactions URL, enabling named-app slash
+  commands, changing the existing default app, or broadening Discord/OpenBao
+  permissions.
+- Never: commit or print tokens, share one token file between named apps,
+  accept ambiguous binding resolution, restart the retired Gas City Inc city,
+  or allow one app failure to terminate all gateway workers.
+
+The additive `apps` registry currently shares schema version 1 with the legacy
+config. Before rolling back to a pack version that does not understand it,
+back up the config and secrets and avoid legacy config-mutating commands, which
+would normalize the unknown registry away.
+
+## Success Criteria
+
+- A city can connect at least three named Discord bots concurrently.
+- Mentioning each bot in the same room routes only to its bound Gas City
+  session.
+- `reply-current` posts as the bot that received the turn.
+- Importing one app cannot overwrite another app's metadata or token.
+- Existing single-app fixtures and live cities require no migration.
+- Status reports each app's health and counters without exposing credentials.
+- The complete Discord test suite passes, followed by live tests with zero
+  failed or dropped messages.
+
+## Open Questions
+
+None for this slice. Named-app interactions and command sync are intentionally
+deferred until there is a consumer for them.

 ## Choosing an entrypoint
 
-| You have | Launch | Notes |
-| -------- | ------ | ----- |
-| Just an idea | `build-basic` (targeted at a bead) | Full lifecycle from requirements onward. |
-| Approved requirements | `build-from-plan` | Produces plan + plan review, then continues. |
-| Approved requirements, plan, and plan review | `build-from-decompose` | Starts at decomposition. |
-| An implementation convoy | `build-from-convoy` | Drains the convoy, then reviews. |
-| Implementation evidence | `build-from-review` | Review, repair/restart handoff, finalize, publish. |
-| An approved convoy, no build wrapper wanted | `implement` | Direct drain without the review/publish suffix. |
-| A GitHub issue or PR URL | `github-issue-triage`, `github-issue-fix`, `github-pr-review` | Targetless adapters; see GitHub Adapter Workflows below. |
+An idea or request is the input to the Software Development Lifecycle (SDLC).
+The `build-from-*` continuation formulas are named for the point where they
+enter it. For example, `build-from-requirements` starts at Requirements and
+gathers requirements from the idea or request you provide.
+
+Each full-lifecycle formula runs from its starting phase through a complete,
+tested, and reviewed implementation with any required review fixes applied,
+plus a final report. The result may remain local, be pushed, or be published
+as a PR.
+
+The SDLC phases are:
+
+- Requirements
+- Implementation Planning
+- Plan Review
+- Plan Decomposition into beads
+- Implementation and Testing
+- Implementation Review/Fix
+- Finalization
+- Optional Publication (push or PR)
+
+| What you have | Public formula | SDLC phase you're starting from |
+| --- | --- | --- |
+| A target bead containing an idea or request | `build-basic` | Requirements |
+| An idea or request, but no target bead | `build-from-requirements` | Requirements |
+| An approved requirements (aka plan) Markdown file | `build-from-plan` | Implementation Planning |
+| Approved requirements and a reviewed implementation plan | `build-from-decompose` | Plan Decomposition |
+| A Gas City implementation convoy and its requirements, implementation plan, and decomposition | `build-from-convoy` | Implementation |
+
+### Focused workflows
+
+| What you want to do | Public formula | Successful output or boundary |
+| --- | --- | --- |
+| Harden an implementation plan | `design-review` | Revised implementation plan approved or blocked by its review loop |
+| Implement an approved convoy without the full build suffix | `implement` | Implementation summary and optional publication; no normal review/fix/finalize suffix |
+| Resume an existing Gas City build at implementation review | `build-from-review` | Full-lifecycle output described above; requires its upstream build artifacts and implementation evidence |
+| Review an implementation | `review` | Review report only |
+| Check requirements and implementation coverage | `gap-analysis` | Coverage report only |
+| Assess a GitHub issue | `github-issue-triage` | Triage report and a sticky issue comment, created or updated; no implementation |
+| Fix a GitHub issue | `github-issue-fix` | Implemented and reviewed issue fix; sticky issue-fix status comment created or updated; optional draft or ready PR |
+| Review a GitHub PR | `github-pr-review` | Review report and a sticky PR comment for the current head, created or updated; no code changes, formal GitHub review, or merge |
+
+The normal build continuations use one implementation-plan review gate; a required-changes or blocked verdict stops the continuation. `design-review` and `github-issue-fix` provide review loops that harden an implementation plan. Testing evidence is required; TDD is not. `gc.mayor` can gather the upstream artifact paths needed by the continuation formulas.

 Artifact validation: this step is gated by `.gc/scripts/checks/build-artifact-valid.sh`, which validates the report recorded at `gc.build.review_report_path` (fallback `gc.var.report_path`) against schema `gc.build.review.v1`. On repair attempts (`gc.attempt` greater than 1), read the validator errors from `gc.attempt_log` on the validation loop control bead (the dependent of this step bead) and repair the report in place instead of rewriting it. Two bounded repair attempts follow the first failure; exhausting them closes this stage with `gc.outcome=fail` and machine-readable validation errors that block downstream stages. Never ask questions in headless mode; record unresolved ambiguity inside the report.

+`{{report_path}}` is relative to the durable rig root, not the current
+per-bead worktree. Read the rig root from `$GC_RIG_ROOT` and write the report
+to `$GC_RIG_ROOT/{{report_path}}`; do not write it under the current directory
+or `$GC_WORK_DIR`. The inference gate reads the artifact from that durable
+location after this disposable worktree is removed.
+
+Before closing, resolve the workflow-root id from the claimed bead's
+`gc.root_bead_id`, then record the rig-relative path on that root:
+
+```bash
+gc bd update "<workflow-root-id>" \

+Atomically claim one routed workflow bead for current live session.
+
+Usage:
+  gc <binding> claim
+
+The command calls:
+
+```bash
+gc hook --claim --drain-ack --json
+```
+
+For `action=work`, it re-reads claimed bead and verifies its id, open or
+in-progress status, assignee, and route before returning one normalized JSON
+object. Result includes `bead_id`, `root_bead_id`, `continuation_group`, and
+full `bead` record. `action=drain` means no routed work remained and drain
+acknowledgement completed.
+
+Hook and bead-read failures are retried at most three times. Because a failed
+hook may already have assigned work, terminal hook or verification failures
+return non-zero without mutating claims or acknowledging drain. Configuration
+failures detected before the hook still drain-ack before returning non-zero.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-If claim verification fails, the claim command retries `gc hook --claim

-Close it with the requested `gc.outcome` metadata. If the bead does not specify

-
-Never use a bare `bd close` for a bead that asks for close metadata. First set

-
-Finding review issues, missing tests, or required follow-up is usually the

-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-GC_CLAIM
-```
-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.

-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-GC_CLAIM
-```
-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

-If claim verification fails, the claim command retries `gc hook --claim

-Close it with the requested `gc.outcome` metadata. If the bead does not specify

-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

+    The check gates enumerate molecule members with `gc ready` (one leg per
+    --status) rather than a metadata-filtered `gc bd list`, because a collection
+    query carries no bead id and is refused on a city that relocates the graph
+    class. The stub answers every `ready` leg from BD_LIST_JSON, so the union
+    the gate builds is the same member set the old single list call returned.
+
+    `ready` without --metadata-field is rejected: unscoped, it would return the
+    whole city and the gate could read a *different* molecule's verdict. Any
+    other verb exits 2, so a gate that starts shelling out to something new
+    fails here instead of silently reading an empty set.
+
+    A member carrying an explicit "status" is served only by that status's leg;
+    a member without one is served by every leg (the gate dedupes by id). That
+    lets a test place a bead in exactly one leg and prove the gate unions all

+#
+# The gap it closes: a witness whose self-scheduled patrol loop has died still
+# reports a healthy session state. It sits in `asleep` or `active` forever, so
+# the controller's liveness reconcile sees nothing wrong and the deacon's
+# LLM health-scan reads the quiet as legitimate idle. Patrol stalls of 14h to
+# 63h were observed in production this way with no alert. Heartbeat age is the
+# one signal that separates "idle and fine" from "loop is gone", and it is
+# exactly the kind of measurement an LLM should not be eyeballing.
+#
+# For every witness session in a state that implies it should be patrolling
+# (active / awake / asleep / running) it takes the NEWER of `last_active` and
+# `last_nudge_delivered_at` as the heartbeat and compares its age against
+# $GASTOWN_WITNESS_STALE_MIN. Sessions the controller or an operator owns
+# (creating / drained / draining / suspended / quarantined / closed) are the

 ## No Idle Polecats
 
-When implementation and checks are done, run the done sequence immediately.

-pool slot.
+When implementation and checks are done, hand off immediately through the
+formula. There is no approval wait. An idle polecat blocks the refinery and
+wastes the pool slot.
 
-### The Done Sequence
+### The Done Sequence Lives in the Formula
+
+The `mol-polecat-work` `submit-and-exit` step is the single source of truth for
+handoff — branch-shape gate, push + push-verify, metadata, refinery
+reassignment, wake/nudge, and drain. **Run that step.**
+
+**Do NOT run submit-and-exit twice** — running the done sequence twice is a bug.
+Do not trust memory for this; check mechanically. Derive the work bead from your
+convoy exactly as the formula's workspace-setup step does — never pass a bare or
+guessed id to `bd`, which fuzzy-matches and can reassign the wrong bead.
+`$GC_BEAD_ID` is the convoy the molecule was poured on. If a clean read shows
+the work bead is no longer `in_progress` for this session, submit-and-exit
+already reassigned it — drain and exit. Otherwise run it:
 
 ```bash

-{{ define "gc-role-worker" -}}
-# GC Role Worker
-
-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template
-`{{ .TemplateName }}`.
-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

-
-If claim verification fails, the claim command retries `gc hook --claim
---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

+
+## Optional executive status brief
+
+The `city-executive-status` skill packages the shareable workflow for requesting
+structured project-owner updates, validating them, and writing one concise
+portfolio brief. It can optionally publish a content-hash-deduplicated summary
+through a deployment-specific adapter.
+
+Importing this pack exposes the skill but does not activate its example
+schedules or write to a vault. The only active pack orders remain
+`patrol-project-leads` and `escalate-rollups`. To enable the workflow, follow the
+skill's `SKILL.md`, copy its environment and order examples into the consuming
+city, configure local paths, and verify dry-run output before scheduling writes.
 
 ## Requirements
 
 - An extmsg/slack adapter in the city for outbound delivery and inbound replies — **compose this pack with your slack pack** (e.g. `slack-full`, `slack-channel`, or `slack-mini`). This pack ships only the oversight role and its escalation machinery, not a slack bridge.
 - Optional: the project-lead's rig-scoped dispatch examples use convoy formulas (`mol-decompose`, `mol-pr-from-issue`) supplied by a workflow pack (e.g. `gastown`). The role works without them.
+- Optional: the executive-status skill needs Python 3.11 or newer. Obsidian and a publishing adapter are not required; without them it writes ordinary Markdown to a configured path.

+description: Maintain a concise, high-level portfolio brief from structured project-owner updates, with Obsidian-compatible Markdown output and optional deduplicated publishing. Use when setting up, sharing, operating, or troubleshooting an executive-status workflow for a multi-agent city or collection of projects.
+---
+
+# City Executive Status
+
+Maintain one current portfolio brief without asking deterministic code to make
+semantic judgments. Project owners describe outcomes and risks; bundled scripts
+only request, validate, aggregate, write, and optionally publish those inputs.
+
+## Preserve the boundary
+
+- Let each project owner decide `health`, `current`, `next`, and `risk` from its
+  real project context.
+- Keep the scripts mechanical. Do not add keyword scoring, inferred health, or
+  automatic rewriting of owner statements.
+- Give every owner exactly one file named `<owner>.md`. Reject owner/filename
+  mismatches and malformed inputs.
+- Write the aggregate atomically. Preserve an existing brief when no valid
+  inputs are available.
+- Treat the vault as live production data. Preview paths and output before
+  enabling scheduled writes.
+
+## Install or share
+
+Prefer importing the containing `oversight-rig` pack in a Gas City workspace.
+The skill is inert until its configuration and example orders are copied into
+that workspace. For a standalone installation, copy this entire
+`city-executive-status/` directory into either a repository's `.claude/skills/`
+directory or the recipient's Codex skills directory. Keep the scripts,
+references, assets, tests, and `agents/openai.yaml` together.
+
+Read [references/configuration.md](references/configuration.md) when installing,
+changing paths, adding a publisher, or adapting the scheduler. Copy and edit the
+bundled environment, input, and order examples rather than inventing new formats.
+
+## Run the workflow
+
+1. Configure paths and command templates from
+   `assets/executive-status.env.example`.
+2. Copy `assets/status-input-template.md` once per owner, naming each copy
+   `<owner>.md` and setting its `owner` field to the same value.
+3. Preview update requests:
+
+   ```bash
+   python3 scripts/request_status_updates.py \
+     --agents-dir ./agents \
+     --input-dir ./executive-status/inputs \
+     --dry-run
+   ```
+
+4. Configure `EXECUTIVE_STATUS_DISPATCH_COMMAND`, then run the same command
+   without `--dry-run`. The command template is parsed without a shell and must
+   contain `{agent}` and `{message}`.
+5. Preview the aggregate:
+
+   ```bash
+   python3 scripts/executive_status_sync.py --dry-run
+   ```
+
+6. Run with `--no-publish` to update only the Markdown brief. Configure
+   `EXECUTIVE_STATUS_PUBLISH_COMMAND` only after the user explicitly authorizes
+   the external destination. Publishing is content-hash deduplicated.
+7. Stagger the request and aggregation schedules so owners have a composition
+   window. Use the examples under `assets/orders/` as starting points.
+
+## Interpret failures
+
+- A malformed input is reported by filename and makes the sync exit nonzero;
+  valid inputs are still visible with a coverage warning.
+- Zero valid inputs makes the sync fail closed without replacing the existing
+  brief.
+- A failed dispatch or publish command propagates as an error. Do not mark its
+  sentinel complete or hide it with a default value.
+- Stale inputs remain visible as `Stale`; they are not silently dropped.
+
+## Verify changes
+
+Run all unit, integration, end-to-end, package-completeness, and scrub tests:
+
+```bash
+python3 -m unittest discover -s tests -v
+```
+
+Then validate the skill structure with the `skill-creator` validator.

+# Configuration
+
+## Data flow
+
+```text
+scheduled request
+  -> one model-authored Markdown input per owner
+  -> structural validation
+  -> deterministic portfolio brief in the vault
+  -> optional content-hash-deduplicated publisher
+```
+
+The input files are the semantic boundary. The requester supplies the exact
+schema; the aggregator never infers health or rewrites project meaning.
+
+## Environment variables
+
+| Variable | Used by | Default | Purpose |
+| --- | --- | --- | --- |
+| `EXECUTIVE_STATUS_INPUT_DIR` | both | `executive-status/inputs` | Owner input directory |
+| `EXECUTIVE_STATUS_AGENTS_DIR` | requester | unset | Discover `*-pl/agent.toml` owners |
+| `EXECUTIVE_STATUS_DISPATCH_COMMAND` | requester | unset | Shell-free command template containing `{agent}` and `{message}`; `{subject}` is optional |
+| `EXECUTIVE_STATUS_SUBJECT` | requester | `DIRECTIVE: EXECUTIVE_STATUS` | Dispatch subject |
+| `EXECUTIVE_STATUS_DISPATCH_TIMEOUT` | requester | `30` | Per-owner command timeout in seconds |
+| `EXECUTIVE_STATUS_OUTPUT` | sync | `executive-status/Executive Brief.md` | Aggregate Markdown path, normally inside the vault |
+| `EXECUTIVE_STATUS_TITLE` | sync | `Executive Status Brief` | Brief and publish-summary title |
+| `EXECUTIVE_STATUS_EXPECTED_OWNERS` | sync | unset | Comma-separated owners used for coverage reporting |
+| `EXECUTIVE_STATUS_STALE_HOURS` | sync | `48` | Age at which an input is shown as stale |
+| `EXECUTIVE_STATUS_PUBLISH_COMMAND` | sync | unset | Shell-free command template requiring `{body_file}`; `{title}` is optional |
+| `EXECUTIVE_STATUS_PUBLISH_TIMEOUT` | sync | `90` | Publisher timeout in seconds |
+| `EXECUTIVE_STATUS_MAX_PUBLISH_LENGTH` | sync | `3500` | Maximum summary length |
+| `EXECUTIVE_STATUS_SENTINEL` | sync | beside output | Last successfully published summary hash |
+| `EXECUTIVE_STATUS_LOG` | sync | beside output | Append-only audit log |
+
+Command templates are split with `shlex` and executed directly. Shell syntax,
+pipes, redirects, substitutions, and environment expansion are intentionally not
+evaluated. Use a small adapter executable when an integration needs them.
+
+## Installation
+
+1. Copy `assets/executive-status.env.example` outside the skill and set local
+   paths and command adapters.
+2. Create the configured input directory.
+3. Create one input from `assets/status-input-template.md` per expected owner.
+4. Run both scripts in dry-run mode.
+5. Run the sync with `--no-publish` and inspect the generated Markdown in the
+   vault.
+6. Configure publishing only with explicit authorization for that destination.
+7. Install the two scheduler examples, replace their placeholder script paths
+   with the copied or provider-materialized skill directory, and adjust their
+   cadence. Leave enough time between request and aggregation for agents to
+   write their inputs.
+
+## Input contract
+
+Each input must have both fences and exactly these fields:
+
+```text
+project, owner, updated, health, current, next, risk
+```
+
+`owner` must match the filename. `updated` must be an ISO-8601 timestamp with a
+timezone. Health is one of `on-track`, `at-risk`, `blocked`, or `parked`.
+Project and owner are limited to 80 characters; current, next, and risk are
+limited to 240 characters each.
+
+Inputs must be regular Markdown files no larger than 64 KiB. Symbolic links are
+rejected so an input directory cannot redirect the reader elsewhere. Raw HTML
+characters are escaped before owner content enters the brief or publish summary.
+
+Use `blocked` only when the project cannot make useful progress. Use `at-risk`
+when progress continues but an outcome is threatened. Use `parked` for deliberate
+inactivity. Keep internal work IDs, paths, branches, queue counts, and incident
+mechanics out of the brief.
+
+## Adapters
+
+For a Gas City installation, a dispatch adapter can invoke `gc mail send` with
+the `{agent}`, `{subject}`, and `{message}` arguments. A publishing adapter can
+invoke any approved channel command that accepts a Markdown file path. Keep
+platform-specific identifiers and credentials in the deployment environment,
+not in this skill.

+accounts to this loop in 2026-08-22. The numbers needed to refuse are already in
+hand one step above; the only thing that made this expensive was not comparing
+them.
+
+**Exit 0 is deliberate.** The refusal is a completed decision, not an error, and
+must not present to a supervising loop as a failure to retry. The verdict
+`too_large` is distinct from `approve`, nothing was reviewed, and the report
+says so rather than implying the PR is clean.

+# PR Review Pack
+
+Formula-driven adopt-PR workflow for Gas City. Reviews contributor
+PRs using a multi-model review engine (Claude + Codex + Gemini), with a human
+gate before finalize and a publish/merge handoff to mayor.
+
+## What's Included
+
+- **`mol-adopt-pr` formula** — 5-step molecule: intake, rebase-check, review,
+  human-gate, finalize
+- **`/review-pr` skill** — multi-model code review engine (overlay)
+
+## Prerequisites
+
+- `gh` CLI authenticated with repo access
+- Polecat agent (from consuming pack) with worktree support
+- `bd` CLI for bead operations
+
+## Usage
+
+Sling a PR review to a polecat:
+
+```bash
+gc sling <rig>/polecat mol-adopt-pr --formula \
+  --var pr=https://github.com/org/repo/pull/42
+```
+
+With bare integer (uses current repo):
+
+```bash
+gc sling <rig>/polecat mol-adopt-pr --formula --var pr=42
+```
+
+Skip Gemini (dual-model mode — Claude + Codex only):
+
+```bash
+gc sling <rig>/polecat mol-adopt-pr --formula \
+  --var pr=42 --var skip_gemini=true
+```
+
+## Workflow
+
+1. **Intake** — Parse PR, fetch metadata, validate scope, checkout branch
+2. **Rebase check** — Auto-rebase straightforward conflicts, reject complex ones
+3. **Review** — Run `/review-pr` (parallel Claude + Codex + Gemini)
+4. **Human gate** — Blocks until maintainer closes the step manually:
+   ```bash
+   gc bd close <human-gate-step-id>
+   ```
+5. **Finalize** — Resolve merge path, prepare local artifacts (squash/rebase/branch/synthesis), hand publish + merge to mayor, then clean up refs and update the root bead
+
+## Merge Paths
+
+| Path | Condition | Strategy |
+|------|-----------|----------|
+| A | No maintainer changes | Squash merge |
+| B | Maintainer changes + edits enabled | Merge commit (preserves dual authorship) |
+| C | Maintainer changes + edits disabled | New PR from maintainer's fork |
+| D | Original PR already merged | Follow-up PR for fixups |
+
+## Importing into pack.toml
+
+```toml
+[imports.pr-review]
+source = "../packs/pr-review"
+```

+description = """
+Adopt-PR workflow — 5 steps from intake through merge-handoff.
+
+Sling a contributor PR to a polecat for review. The polecat follows each step
+in order; a human gate after review blocks until the maintainer closes it
+manually. Crash-safe: `gc bd mol current` resumes at the right step.
+
+The molecule root bead IS the control bead — all run state is stored in its
+notes via `gc bd update <root-id> --notes "key: value"`. No separate tracking
+bead needed.
+
+**Polecat publish authority (hard rule):** The polecat NEVER runs `gh pr merge`,
+`git push`, `gh pr create`, or `gh pr comment` on paths B/C/D. The `finalize`
+step resolves the merge path, prepares all local artifacts (squash, rebase,
+branch, cherry-pick, synthesis body), then for paths B/C/D records a
+*branch-ready handoff bundle* (`status: ready-for-publish` plus the resolved
+publish + comment + merge commands) in the root bead, and mails mayor. The
+finalize cleanup ends the chain. Mayor performs publish (push + optionally
+`gh pr create`), posts the synthesis comment (`gh pr comment`), waits for CI,
+and merges asynchronously per the per-action approval rule, independent of the
+polecat's lifecycle. Path A is the contributor's own PR branch round-trip — the
+polecat still pushes the rebased contributor commits there (no new artifact
+under maintainer identity), posts the synthesis comment on the contributor's
+existing PR itself, and only hands off `gh pr merge` to mayor.
+
+## Contract
+
+1. Caller slings with `--var pr=<url-or-number>` (and optionally `--var skip_gemini=true`)
+2. Polecat reads steps, executes each in order
+3. After review, human-gate blocks until maintainer closes it
+4. Polecat resumes finalize → resolves merge path → prepares all local artifacts
+5. Path A: polecat pushes rebased contributor commits, posts synthesis, waits CI,
+   records merge_command, mails mayor; finalize cleanup ends the chain
+6. Paths B/C/D: polecat records branch-ready handoff bundle (push_command +
+   optional pr_create_command + synthesis body + merge_command) in root bead,
+   mails mayor; finalize cleanup ends the chain. Polecat does NOT push, create,
+   comment, wait CI, or merge on B/C/D.
+7. Mayor reads the root bead and performs publish + downstream actions
+   out-of-band, per the per-action approval rule
+

+
+| Variable | Source | Description |
+|----------|--------|-------------|
+| pr | caller | PR URL or bare integer (required) |

+
+## Failure Modes
+
+| Situation | Action |
+|-----------|--------|
+| gh command fails | Check `gh auth status`, report error, stop |
+| Rebase has complex conflicts | Abort rebase, post comment, close root bead, stop |
+| Push fails | Report error, stop. User resolves manually |
+| CI fails | Report failure, stop, wait for human-gate or nudge |
+| Review-pr fails | Report which step failed, stop. Retry on next nudge |"""

+Parse the PR, fetch metadata, validate scope, checkout the branch, and record
+initial state in the root bead notes.
+
+**1. Find the root bead and claim it (BEFORE any `git checkout`):**
+```bash
+ROOT_ID=$(gc bd mol current --json | jq -r '.molecule_id')
+gc bd update "$ROOT_ID" --claim
+```
+
+`gc bd update --claim` atomically sets assignee to your session and transitions
+status to `in_progress` (idempotent if already claimed by you). The claim
+**MUST** happen before any `git checkout` of the contributor's branch.
+Otherwise the bead stays `OPEN/assignee=none/started=no` while real review
+work is in flight, and monitoring reads false stalls.
+
+**2. Parse PR identifier from `{{pr}}`:**
+- If `{{pr}}` matches `https://github.com/.*/pull/\\d+` → extract owner, repo, PR number from URL
+- If `{{pr}}` is a bare integer → use current repo (`gh repo view --json nameWithOwner -q .nameWithOwner`)
+
+**3. Fetch PR metadata:**
+```bash
+gh pr view <number> --json title,body,author,baseRefName,headRefName,number,additions,deletions,changedFiles,maintainerCanModify,url,mergeable
+```
+
+**4. Validate PR scope:**
+
+Fetch changed files:
+```bash
+gh pr view <number> --json files --jq '.files[].path'
+```
+
+Compare against the PR title/description. If the changes are clearly outside
+the described scope (e.g., a "fix typo" PR that touches dozens of packages),
+the branch has diverged from main. **Do NOT reflexively request changes** —
+scope divergence is usually salvageable by us (rebase + finalize). Record the
+status and continue:
+- Record in root bead notes: `scope_status: diverged` (or `scope_status: clean`).
+- Continue to the `rebase-check` step. The default route is **take-the-good**:
+  we rebase the branch onto main ourselves, drop the stray commits, and the
+  review/finalize machinery merges the in-scope change.
+- Only `gh pr review <number> --request-changes` here when the divergence is
+  UNSALVAGEABLE *and* genuinely needs the author — i.e. one of the reserved
+  cases holds: **cant-reproduce**, **needs-author-input** (secret/env/design
+  intent / `maintainerCanModify = false`), or **author-wants-to-iterate**. When
+  you do, name the case in the RC body and `gc bd close $ROOT_ID --reason
+  "request_changes: <case>"`, then exit.
+
+**5. Check maintainer edits:**
+Record in root bead notes: `maintainer_edits: true` or `maintainer_edits: false`.
+If false, warn but continue — Phase 6 uses Path C if maintainer changes exist.
+
+**6. Stage a per-PR worktree and checkout the branch:**
+
+Do **NOT** run `gh pr checkout` in place. A fresh polecat shell starts in the
+persistent slot worktree (`/home/ds/gascity-worktrees/polecat-N`), which may
+hold another molecule's in-progress WIP; an in-place checkout clobbers/stashes
+it. Stage an ephemeral per-PR worktree instead (polecat-prompt Mode 4
+convention) and check the PR out there:
+
+```bash
+PR_WORKTREE="/home/ds/gascity-worktrees/adopt-pr-<number>"
+EXPECTED_BRANCH="<headRefName>"
+
+if [ -d "$PR_WORKTREE" ]; then
+  # Re-sling: a prior run already staged this worktree. Only TRUST it if it is
+  # on the expected PR branch AND clean. Otherwise fail loud — never silently
+  # clobber, stash, or build review work on top of unknown state.
+  cd "$PR_WORKTREE"
+  WT_BRANCH=$(git branch --show-current)
+  if [ "$WT_BRANCH" != "$EXPECTED_BRANCH" ] || [ -n "$(git status --porcelain)" ]; then
+    echo "[adopt-pr] FATAL: staged worktree $PR_WORKTREE is on branch '$WT_BRANCH' (expected '$EXPECTED_BRANCH') or has uncommitted changes." >&2
+    gc bd update "$ROOT_ID" --set-metadata "gc.halt_chain=true" \\
+      --set-metadata "summary_for_human=adopt-pr intake found a dirty or wrong-branch staged worktree at $PR_WORKTREE (branch '$WT_BRANCH', expected '$EXPECTED_BRANCH'). Inspect it, then 'git worktree remove --force $PR_WORKTREE' before re-slinging."
+    gc bd close "$ROOT_ID" --reason "dirty/wrong-branch staged worktree in intake"
+    exit 1
+  fi
+else
+  git worktree add --detach "$PR_WORKTREE"
+  cd "$PR_WORKTREE"
+fi
+
+gh pr checkout <number>
+```
+
+Record the staging directory on the root bead. Every later step runs in a
+fresh shell that otherwise lands back in the slot worktree, so they re-enter
+`work_dir` from this metadata:
+```bash
+gc bd update "$ROOT_ID" --set-metadata "work_dir=$PR_WORKTREE"
+```
+
+**7. Record state in root bead notes:**
+```bash
+gc bd update $ROOT_ID --notes "pr_number: <N>
+pr_url: <url>
+repo: <owner/repo>
+pr_title: <title>
+pr_author: <author.login>

+**6. Handle conflicts (if rebase paused):**
+
+For each conflicting file, classify:
+- **Non-PR file** (not in PR_FILES) → `git checkout --theirs <file> && git add <file>`. Safe.
+- **Redundant commit** (PR file, but upstream already has identical content) → `git rebase --skip`. Safe.
+- **Add/add conflict** (PR file, empty base section in diff3 markers) → resolve with union merge:
+  ```bash
+  git show :1:"$file" > /tmp/base; git show :2:"$file" > /tmp/ours; git show :3:"$file" > /tmp/theirs
+  cp /tmp/ours /tmp/union
+  git merge-file --union /tmp/union /tmp/base /tmp/theirs
+  ```
+  Validate: no conflict markers survive, all PR additions present. If valid → `cp /tmp/union "$file" && git add "$file"`.
+- **Modify/modify conflict** (non-empty base section) → **complex**, abort.
+
+If complex conflicts found:
+```bash

+```
+
+Post: `gh pr comment <number> --body "<comment>"`
+
+**A.2: Wait for CI.**
+
+First verify CI checks exist:
+```bash
+gh pr checks <number>
+```
+If no checks reported → **STOP**, print message telling maintainer to approve
+GitHub Actions workflow run. Wait for nudge.
+
+Once checks exist:
+```bash
+gh pr checks <number> --watch
+```
+If CI fails → **STOP**, report failure, wait for nudge.
+
+**A.3: Push rebased branch (if applicable).**
+If rebase was performed (`rebase_status` is not `not_needed`):
+```bash
+git push --force-with-lease
+```
+
+**A.4: Hand off the merge to mayor.**
+**Polecats NEVER run `gh pr merge`.** Record the resolved merge command +
+readiness flag in the root bead, mail mayor, and proceed to A.5 — do NOT
+run the merge yourself. The maintainer (via mayor) performs the merge
+out-of-band per the per-action approval rule.
+
+```bash
+gc bd update $ROOT_ID --notes "<notes with merge_path: A, merge_ready: true, status: ready-for-merge, merge_command: 'gh pr merge <number> --squash'>"
+```
+
+Then mail mayor:
+```
+[adopt-pr] Path A ready for merge — synthesis posted, CI green, no maintainer changes.
+[adopt-pr]   PR:            <number>
+[adopt-pr]   Merge command: gh pr merge <number> --squash
+[adopt-pr]   Root bead:     $ROOT_ID
+```
+
+The polecat then runs A.5 (cleanup), the final step in the molecule. Mayor's
+merge happens asynchronously — the polecat's own lifecycle does not wait for it.
+
+**A.5: Cleanup and final report (terminal — all paths).**
+
+Remove the temporary upstream-base ref and reclaim the per-PR worktree the
+`intake` step staged. This is the last step on every path (there is no separate
+`complete` step); the polecat's work ends here. Keep the per-path status already
+recorded (`ready-for-merge` for Path A, `ready-for-publish` for B/C/D) — the
+merge/publish itself is mayor's asynchronous work, so the polecat does not mark
+the PR "merged".
+
+`cd` out of the staged worktree before removing it (git refuses to remove the
+worktree you are standing in), then force-remove it so the slot is reclaimed on
+the success path of every merge path (A/B/C/D). Earlier-step halts (intake
+request-changes, rebase-check abort) `exit` without reaching here and leave
+their `adopt-pr-<N>` worktree in place; that is intentional and bounded — the
+worktree path is deterministic per PR number, so a re-sling of the same PR
+REUSES it (guarded clean + on-branch in intake) rather than accumulating, and a
+re-sling that runs to completion reclaims it here:
+```bash
+WORK_DIR=$(gc bd show "$ROOT_ID" --json | jq -r '.[0].metadata.work_dir // empty')
+git update-ref -d refs/adopt-pr/upstream-base 2>/dev/null || true
+MAIN_WT=$(git worktree list --porcelain | awk '/^worktree /{print $2; exit}')
+cd "$MAIN_WT" 2>/dev/null || cd /
+if [ -n "$WORK_DIR" ]; then
+  git worktree remove --force "$WORK_DIR" 2>/dev/null || true
+fi
+```
+
+**Report:**
+```

+[adopt-pr]   Merge path: <A|B|C|D>
+[adopt-pr]   Status:     <ready-for-merge | ready-for-publish>

+
+---
+
+### Path B: Merge Commit (maintainer changes present)
+
+**B.1: Squash contributor commits (if >1).**
+```bash

+```
+
+If `CONTRIBUTOR_COUNT > 1`:
+```bash
+# Get contributor authorship

+AUTHOR_EMAIL=$(git log --format="%ae" $ORIGINAL_HEAD -1)
+AUTHOR_DATE=$(git log --format="%aD" $ORIGINAL_HEAD -1)

+OLD_TIP=$(git rev-parse HEAD)
+BASE_SHA=$(git rev-parse refs/adopt-pr/upstream-base)
+MERGE_BASE=$(git merge-base refs/adopt-pr/upstream-base $ORIGINAL_HEAD)
+
+# Rebase contributor commits onto upstream-base, then squash

+git rebase --onto refs/adopt-pr/upstream-base $MERGE_BASE
+REBASED_TREE=$(git rev-parse HEAD^{tree})

+  GIT_AUTHOR_DATE="$AUTHOR_DATE" \
+  git commit-tree "$REBASED_TREE" -p "$BASE_SHA" -m "<pr_title> (#<number>)")
+
+git checkout $SQUASH_SHA
+git cherry-pick ${ORIGINAL_HEAD}..${OLD_TIP}
+git checkout -B <branch-name> HEAD
+```
+
+**Guardrails (all four must pass, else restore and STOP):**
+1. Contributor diff identity — sorted added/removed lines match original
+2. File count — squashed commit touches same files as original
+3. Commit count — exactly 1 + MAINTAINER_COMMIT_COUNT
+4. Authorship — contributor name/email preserved
+
+If any fails: `git checkout -B <branch> $OLD_TIP` and **STOP**.
+
+**B.2: Hand off branch-ready bundle to mayor.**
+**Polecats NEVER run `git push` or `gh pr merge` on Path B.** B.1 already
+rewrote the contributor branch locally with maintainer changes squashed in;
+publishing that rewrite under maintainer identity is mayor's per-action
+publish step.
+
+Resolve the push command. `REBASE_STATUS` is the shell variable carrying the
+`rebase_status` field extracted from root bead notes in step 1 (see also
+A.3, which reads the same field):
+```bash
+REBASE_STATUS=$(bd_notes_get "$ROOT_ID" rebase_status)   # extracted in step 1
+if [ "$CONTRIBUTOR_COUNT" -gt 1 ] || [ "$REBASE_STATUS" != "not_needed" ]; then
+    PUSH_CMD="git push --force-with-lease"
+else
+    PUSH_CMD="git push"
+fi
+```
+
+Compose the Path B synthesis comment body (template — includes Initial Review,
+Maintainer Changes, Final Review Status sections) into a file:
+```bash
+SYNTH_PATH="<review_run_dir>/outputs/comment-path-b.md"
+# write the rendered comment body to $SYNTH_PATH
+```
+
+Resolve concrete handoff values and record the full branch-ready handoff
+bundle on the root bead. Use double-quoted command strings so `$SYNTH_PATH`
+and other shell variables expand at write time — the notes must contain
+fully resolved, copy-pasteable commands for mayor:
+```bash
+HEAD_SHA=$(git rev-parse HEAD)
+POST_SYNTH_CMD="gh pr comment <number> --body-file $SYNTH_PATH"
+CI_WAIT_CMD="gh pr checks <number> --watch"
+MERGE_CMD="gh pr merge <number> --merge"
+
+gc bd update "$ROOT_ID" --notes "<notes with
+  merge_path: B,
+  status: ready-for-publish,
+  branch: <head_ref>,
+  head_sha: $HEAD_SHA,
+  push_command: $PUSH_CMD,
+  synthesis_path: $SYNTH_PATH,
+  post_synthesis_command: $POST_SYNTH_CMD,
+  ci_check_command: $CI_WAIT_CMD,
+  merge_command: $MERGE_CMD>"
+```
+
+Then mail mayor (variable values shown for the example; substitute actual

+
+**B.3: Cleanup** (same as Path A.5).

+---
+

+**Polecats NEVER run `git push`, `gh pr create`, or `gh pr merge` on Path C.**
+C.1–C.3 prepared the new branch locally under maintainer identity; publishing
+that branch as a new upstream PR is mayor's per-action publish step.
+
+Compose the Path C synthesis comment body (credits contributor) and the
+original-PR thank-you/close comment into files:
+```bash
+SYNTH_PATH="<review_run_dir>/outputs/comment-path-c.md"
+CLOSE_PATH="<review_run_dir>/outputs/comment-path-c-original-close.md"
+# write the rendered bodies
+```
+
+Resolve concrete handoff values and record the full branch-ready handoff
+bundle on the root bead. Build each command in a shell variable first so the

+D.1–D.2 prepared the follow-up branch locally under maintainer identity;

+
+The polecat then runs D.4 (cleanup), the final step. Mayor performs
+push → create follow-up PR → post synthesis → wait CI → merge → comment on
+original asynchronously per the per-action approval rule.
+
+**D.4:** Cleanup (same as Path A.5).
+
+---
+
+**Critical rules for all paths:**
+- **No force-push** except after contributor squash or rebase (always `--force-with-lease`)
+- **Contributor credit preserved** — squash commit keeps original author
+- **CI checks must exist** — never merge without CI. First-time forks need manual approval.
+- **Squash guardrails mandatory** — all four checks must pass before pushing rewritten history
+- **All reviews use canonical upstream base** — fetched from the real upstream URL, not origin
+
+**Exit criteria:** Merge path resolved. Then:
+- **Path A:** synthesis posted, CI green, `merge_ready: true` + `merge_command`
+  recorded in root bead notes, mayor mailed, A.5 cleanup run.
+- **Paths B/C/D:** local artifacts prepared (squash / branch / cherry-pick /
+  synthesis body), `status: ready-for-publish` + full publish-and-merge bundle
+  recorded in root bead notes, mayor mailed, A.5 cleanup run — without pushing,
+  creating PRs, posting comments, waiting on CI, or merging.
+
+The polecat never invokes `gh pr merge` on any path, and never invokes
+`git push` or `gh pr create` on paths B/C/D. Mayor performs publish and
+downstream actions asynchronously per the per-action approval rule,
+independent of the polecat's lifecycle."""

+description = """
+Iterate-PR workflow — 6 steps to address feedback on an outgoing PR.
+
+Source-agnostic pipeline that ingests feedback from one of four sources
+(codecov coverage report, GitHub Copilot review, a specific review comment,
+or free text), proposes a minimal patch, applies it on the PR branch,
+verifies the feedback is cleared, and reports.
+
+This is the *outgoing-PR* iteration analogue to mol-adopt-pr (incoming) and
+mol-pr-from-issue (issue → PR). It does NOT push or open PRs — the polecat
+commits to the local PR branch and the maintainer pushes after review.
+
+The molecule root bead IS the control bead — all run state is stored in its
+notes via `gc bd update <root-id> --notes "key: value"` and structured
+evidence in metadata via `gc bd update <root-id> --set-metadata "key=value"`.
+
+## Contract
+
+1. Caller slings with `--var pr=<int> --var feedback_source=<source>`
+   (and optionally `--var feedback_ref=<id-or-url-or-text>`).
+2. Polecat works through 6 sequential steps with explicit per-step gates.
+3. Chain ends with either:
+   - PR branch updated with a commit addressing the feedback, OR
+   - a halt with `metadata.summary_for_human` set on the root bead
+     and (when the bead specifies) an explicit mail to mayor.
+
+## Variables
+
+| Variable | Source | Description |
+|----------|--------|-------------|
+| pr | caller | PR number on the current repo's upstream (required, int) |
+| feedback_source | caller | One of: codecov, copilot, review-comment, text (required) |
+| feedback_ref | caller | Comment id, codecov report URL, or inline feedback text (optional; required for review-comment and text) |
+
+## Halt-and-mail-mayor conditions
+
+The polecat halts the chain AND mails mayor when:
+- **Feedback ambiguity** — parse-feedback cannot extract a structured
+  actionable signal from the source (e.g., codecov report unavailable,
+  copilot comments contain no concrete suggestions, text input is too
+  vague to plan from).
+- **Scope exceeds 200 LOC** — propose-patch's plan exceeds 200 LOC of
+  changes (sum of additions + deletions across affected files).
+- **Verify-clearance fails after 2 iterations** — apply + verify-clearance
+  has run twice without clearing the feedback signal.
+
+Halt-and-mail-mayor procedure (used by any step that hits one of the above):
+```bash

+| Cannot checkout PR branch (e.g. closed PR) | intake halts |
+| feedback_source not in enum | parse-feedback halts immediately |
+| feedback_ref missing when required | parse-feedback halts (review-comment/text need a ref) |
+| Codecov report URL unreachable | parse-feedback halts (ambiguity) |
+| Build fails after apply | apply halts; do NOT commit broken state |
+| Plan exceeds 200 LOC | propose-patch halts-and-mails-mayor |
+| Same feedback signal still present after 2 iterations | verify-clearance halts-and-mails-mayor |
+
+## Notes
+
+- No `auto_push` integration. The polecat never pushes; the maintainer
+  reviews the local commit and pushes manually.
+- Iteration counter is tracked in root bead notes (`iteration: N`).
+  apply + verify-clearance increment it on each cycle; verify-clearance
+  reads it to decide whether the halt-after-2 condition has fired."""

+**2. Dispatch on `feedback_source`:**
+
+### Source: codecov
+
+The `feedback_ref` should be a codecov report URL (e.g.
+`https://codecov.io/gh/<owner>/<repo>/pull/<N>`). If empty, attempt to
+locate it from the PR's check runs:
+```bash
+gh pr checks {{pr}} --json name,detailsUrl --jq '.[] | select(.name | test("codecov"; "i")) | .detailsUrl'
+```
+
+Fetch the report (codecov has a public JSON API):
+```bash
+# If feedback_ref is the html URL, derive the API URL.
+# Example: https://codecov.io/api/v2/github/<owner>/repos/<repo>/pulls/<N>
+curl -sf "<api_url>" > /tmp/codecov.json
+```
+
+Extract uncovered lines limited to files changed in the PR diff:
+```bash
+git diff --name-only $BASE_SHA..HEAD > /tmp/pr-files.txt
+# parse /tmp/codecov.json for uncovered lines per file, intersect with /tmp/pr-files.txt
+```
+
+If the report is unreachable, malformed, or shows 100% coverage on PR
+files → **halt-and-mail-mayor** (ambiguity / nothing to do).
+
+### Source: copilot
+
+Fetch PR review comments, filter to copilot bot author:
+```bash
+gh api "/repos/$REPO/pulls/{{pr}}/comments" \\
+  --jq '.[] | select(.user.login == "github-advanced-security[bot]" or .user.login == "copilot-pull-request-reviewer[bot]" or (.user.login | test("copilot"; "i"))) | {id, path, line, body}'
+```
+
+If no copilot comments found → **halt-and-mail-mayor** (ambiguity).
+
+### Source: review-comment
+
+Fetch the specific comment by id:
+```bash
+gh api "/repos/$REPO/pulls/comments/{{feedback_ref}}" \\
+  --jq '{id, path, line, body, user: .user.login}'
+```
+
+If the comment id doesn't exist or returns 404 → halt-and-mail-mayor.
+
+### Source: text
+
+The `feedback_ref` IS the feedback. Use it verbatim:
+```bash
+echo "{{feedback_ref}}" > /tmp/parsed_feedback.txt
+```
+
+If the text is empty or just whitespace → halt-and-mail-mayor.
+
+**3. Write parsed_feedback to root bead notes:**
+
+Serialize the parsed signal as a compact JSON string in notes, e.g.:
+```bash
+gc bd update $ROOT_ID --notes "<existing notes>
+parsed_feedback: <json>"
+```
+
+For codecov: `{\"type\": \"coverage\", \"uncovered\": [{\"file\": \"...\", \"lines\": [12, 15-18]}]}`
+For copilot: `{\"type\": \"copilot\", \"comments\": [{\"id\": ..., \"path\": \"...\", \"line\": ..., \"body\": \"...\"}]}`

+
+A fresh polecat shell starts in the slot worktree, not the per-PR worktree the

+**2. Compose a plan.**
+
+The polecat reads `parsed_feedback` and drafts a markdown plan with:
+- **Goal** — one sentence stating what feedback signal will be cleared.
+- **Files to touch** — explicit list with reason per file.
+- **Estimated LOC** — sum of additions + deletions across the plan.
+- **Diff sketch** — for each file, a brief description of the change
+  (not the literal diff — that comes in `apply`).
+- **Verification** — how `verify-clearance` will confirm the signal is gone.
+
+Write the plan to:
+```bash
+mkdir -p .gc/pr-pipeline/iterate
+PLAN_PATH=".gc/pr-pipeline/iterate/pr-{{pr}}.md"
+# write the plan markdown to $PLAN_PATH
+```
+
+**3. Estimate LOC and enforce 200-LOC cap.**
+
+Compute the estimated LOC from the plan (sum of additions + deletions in
+the Diff sketch). If `EST_LOC > 200`:
+```bash

+                        --set-metadata "gc.escalate_to=mayor" \\

+mid-implementation, revert local changes and halt-and-mail-mayor with

+
+**5. Run build verification.**
+
+The verification command is pack-dependent — check `pack.toml` of the

+- Go packs: `go build ./... && go vet ./...`
+- Python packs: `python3 -m pytest`
+- Mixed: run the pack's `tests/` script

+`last_apply_commit`.
+
+**2. Source-specific verification:**
+
+### codecov
+
+Codecov coverage is computed by CI. The polecat cannot directly re-trigger
+codecov — instead, the apply commit is local and unpushed, so codecov has
+nothing new to score. Mark verification as **deferred-to-push**:
+```bash
+gc bd update "$ROOT_ID" --set-metadata "evidence.verification=deferred-to-push" \\
+                        --set-metadata "evidence.verification_note=Codecov verification runs after maintainer pushes commit $last_apply_commit. Re-sling mol-pr-iterate after the next codecov run if uncovered lines persist."
+```
+Proceed to `report` (do NOT count this as a failed iteration).
+
+### copilot
+
+Re-query copilot comments. If the original comment(s) are now marked
+`resolved` or absent, signal is cleared.
+
+```bash
+gh api "/repos/$REPO/pulls/{{pr}}/comments" \\
+  --jq '.[] | select(.user.login | test("copilot"; "i")) | select(.in_reply_to_id == null) | {id, body}'
+```
+
+Compare with `parsed_feedback.comments` from earlier. For each prior
+comment, check if it's resolved (GraphQL only — `gh api graphql -F query=...`)
+or no longer present.
+
+If cleared, post a reply on the original copilot thread noting the change:
+```bash
+gh api "/repos/$REPO/pulls/{{pr}}/comments" \\
+  -f body="Addressed in $last_apply_commit." \\
+  -f in_reply_to=<original_comment_id>
+```
+
+### review-comment
+
+Similar to copilot — post a reply to `{{feedback_ref}}`:
+```bash
+gh api "/repos/$REPO/pulls/{{pr}}/comments" \\
+  -f body="Addressed in $last_apply_commit." \\
+  -f in_reply_to={{feedback_ref}}
+```
+
+The polecat does not auto-resolve the comment thread; the reviewer marks
+it resolved.
+
+### text
+
+Free-text feedback has no automated verification. Mark as
+**manual-verification**:
+```bash
+gc bd update "$ROOT_ID" --set-metadata "evidence.verification=manual" \\
+                        --set-metadata "evidence.verification_note=Text feedback addressed in $last_apply_commit. Manual verification by maintainer."
+```
+
+**3. Halt-after-2 check.**
+
+If the signal persists AND `iteration >= 2`:
+```bash
+gc bd update "$ROOT_ID" --set-metadata "gc.halt_chain=true" \\
+                        --set-metadata "gc.escalate_to=mayor" \\
+                        --set-metadata "summary_for_human=PR #{{pr}} feedback signal persists after 2 iterations. Last apply commit $last_apply_commit. Manual review needed."
+gc mail send mayor -s "mol-pr-iterate halt: pr-{{pr}} (verify-clearance failed x2)" \\
+                    -m "Root bead $ROOT_ID. Feedback source {{feedback_source}}, $iteration iterations attempted, signal still present."
+gc bd close "$ROOT_ID" --reason "verify-clearance failed after 2 iterations"
+exit 1
+```
+
+If the signal persists AND `iteration < 2`:
+- Re-enter `parse-feedback` is NOT automatic in this formula — the polecat
+  exits this step and the maintainer (or mayor) decides whether to re-sling
+  for another iteration.

+[iterate]   Ready for maintainer review + push.
+```
+
+**5. Reclaim the staged worktree.**
+
+The durable deliverable is the commit on the PR branch ref — it survives
+worktree removal. The ephemeral per-PR worktree is no longer needed, so remove
+it on the success path to keep per-PR worktrees from accumulating. `cd` to the
+main worktree first (git refuses to remove the worktree you are standing in):
+```bash
+WORK_DIR=$(gc bd show "$ROOT_ID" --json | jq -r '.[0].metadata.work_dir // empty')
+if [ -n "$WORK_DIR" ] && [ -d "$WORK_DIR" ]; then
+  MAIN_WT=$(git -C "$WORK_DIR" worktree list --porcelain | awk '/^worktree /{print $2; exit}')
+  cd "$MAIN_WT" 2>/dev/null || cd /
+  git worktree remove --force "$WORK_DIR" 2>/dev/null || true
+fi
+```
+
+The `iterate-pr-<N>` path is deterministic, so this is idempotent: an
+earlier-step halt leaves that single worktree in place (the plan artifact under
+it is transient — the actionable signal is the commit + `summary_for_human`),
+and a later re-sling of the same PR reuses it (guarded clean + on-branch in
+intake) before this step reclaims it on a clean run.
+
+**Exit criteria:** evidence.* and summary_for_human set on root bead; staged
+worktree reclaimed on the success path; chain is complete; polecat exits
+without pushing or opening a PR."""

+
+Thanks for the contribution, @<author>! Merging via the maintainer's

+```
+
+Post: `gh pr comment <number> --body "<comment>"`
+
+**A.2: Wait for CI.**
+
+First verify CI checks exist:
+```bash
+gh pr checks <number>
+```
+If no checks reported → **STOP**, print message telling maintainer to approve
+GitHub Actions workflow run. Wait for nudge.
+
+Once checks exist:
+```bash
+gh pr checks <number> --watch
+```
+If CI fails → **STOP**, report failure, wait for nudge.
+
+**A.3: Push rebased branch (if applicable).**
+If rebase was performed (`rebase_status` is not `not_needed`):
+```bash
+git push --force-with-lease
+```
+
+**A.4: Squash merge:**

+
+---
+
+**Critical rules:**
+- **No force-push** except after a rebase (always `--force-with-lease`)
+- **Contributor credit preserved** — squash commit keeps original author
+- **CI checks must exist** — never merge without CI. First-time forks need manual approval.

+PR revert — 6 steps to revert a merged PR.
+
+Mayor-only invocation initially (no PL dispatch row). Reverts a merged PR
+via `git revert <merge-sha>` on a fresh branch off `origin/<default>`,
+opens a revert PR upstream, and comments on the original PR with the
+revert-PR URL.
+
+This is a WRITE-side formula. Three of its steps perform writes against
+the upstream repo:
+
+  - `revert-branch` pushes the revert branch to the fork.
+  - `open-revert-pr` calls `gh pr create`.
+  - `comment-on-original` calls `gh pr comment`.
+
+The polecat's default policy forbids `git push`, `gh pr create`, and
+`gh pr edit`. This formula carves out an exception scoped to the
+invocation. The push step is permitted only when ONE of the following
+holds:
+
+  a. Root bead metadata `auto_push == "true"` (set by mayor at sling
+     time via `--metadata auto_push=true`) AND the prior
+     `verify-revertable` step's `evidence.reviewer_verdict == "pass"`.
+  b. Env var `GASCITY_SHIP_BYPASS == "mayor_revert"` — emergency
+     override for cases where the verify-revertable heuristic
+     false-negatives (e.g. complex-but-still-revertable history). The
+     mayor sets this env var in the polecat's invocation environment.
+
+The carve-out is verified once in `revert-branch`; on pass it records
+`evidence.carve_out_verified == "true"` on the root bead. Subsequent
+write steps (`open-revert-pr`, `comment-on-original`) gate on that flag
+so a crash-resumed polecat with no env carryover stays authorized.
+
+This is the same carve-out shape used by mol-pr-from-issue's `open-pr`
+step — scoped to the macro formula's contract, not a polecat-wide
+policy change.
+
+The molecule root bead IS the control bead — all run state lives in its
+notes/metadata. Crash-safe: `gc bd mol current` resumes at the right step.
+
+## Contract
+
+1. Caller (mayor) slings with:
+   `--var pr=<N> --var reason="<text>" --metadata auto_push=true`
+   (or with `GASCITY_SHIP_BYPASS=mayor_revert` in the polecat's env).
+2. Polecat executes steps in order.
+3. Chain ends with either:
+   - an opened revert PR on the upstream repo + a comment on the
+     original PR pointing at the revert PR, OR
+   - a halt with `metadata.summary_for_human` set on the root bead.

+**WRITE STEP — requires auto_push carve-out.**
+
+Creates branch `revert/pr-{{pr}}` off `origin/<default>`, runs
+`git revert --no-edit <merge_sha>`, and pushes to the fork remote.
+
+The polecat's default policy forbids `git push`. This step performs the
+carve-out check ONCE at the top and records the result. If the carve-out
+fails, the step halts BEFORE any upstream write.
+
+**1. Find root bead and read state:**
+```bash
+ROOT_ID=$(gc bd mol current --json | jq -r '.molecule_id')
+META=$(gc bd show "$ROOT_ID" --json | jq '.[0].metadata')
+AUTO_PUSH=$(echo "$META" | jq -r '.auto_push // "false"')

+
+**4. Create the revert branch and run git revert:**
+```bash
+git fetch origin "$DEFAULT_BRANCH"
+BRANCH="revert/pr-{{pr}}"
+git checkout -B "$BRANCH" "origin/$DEFAULT_BRANCH"
+```
+
+Run `git revert`. Use `-m 1` for merge commits (revert the changes
+relative to the first parent, i.e. the base branch). Detect merge vs
+non-merge:
+```bash

+    gc bd close "$ROOT_ID" --reason "git revert conflict"

+fi
+```
+
+**5. Amend the revert commit message to include the reason:**
+
+`git revert --no-edit` produces "Revert \\"<original subject>\\"". Append
+the reason so the commit message references both:
+```bash

+description: >-
+  Multi-model code review for gastown. Reviews GitHub PRs (by URL or number)
+  or local branches (by branch name). Spawns parallel Claude, Codex, and
+  (optionally) Gemini reviewers with specialized prompts optimized for
+  regression prevention, then synthesizes findings into a single
+  maintainer-grade decision report. Use --skip-gemini for dual-model mode
+  when Gemini quota is exhausted. Invoke with /review-pr <pr-url|number|branch>.
+---
+
+# Review PR Orchestrator
+
+You are the **Review PR Orchestrator**. When the user invokes `/review-pr <arg>`, you execute a multi-phase pipeline that produces a thorough, multi-model code review focused on **preventing regressions** in the gastown codebase. You coordinate parallel Claude, Codex, and (unless `--skip-gemini`) Gemini reviewers, merge their findings, and present a single actionable report. All reviewers get full codebase access via temporary worktrees to ensure accurate caller/callee tracing. You never delegate orchestration to a spawned agent -- you are the single controller.
+
+### Mode Detection
+
+`/review-pr <arg>` auto-detects the review mode from `<arg>`:
+
+| Pattern | Mode | Example |
+|---------|------|---------|
+| `https://github.com/.*/pull/\d+` | PR mode | `/review-pr https://github.com/org/gastown/pull/123` |
+| Bare integer | PR mode | `/review-pr 123` |
+| Anything else | Local branch mode | `/review-pr ci/close-stale-needs` |
+
+- **PR mode**: Fetches context from GitHub, posts comment after review (4 phases).
+- **Local branch mode**: Computes diff from local git refs, skips GitHub posting (3 phases).
+
+---
+
+## Pipeline Overview
+
+| Phase | Name | Agents | Modes | Description |
+|-------|------|--------|-------|-------------|
+| 1 | Context Gathering | Orchestrator | Both | Gather metadata + diff; create worktrees for codebase access |
+| 2 | Parallel Review | Claude ∥ Codex ∥ Gemini | Both | Independent reviews with role-specialized prompts |
+| 3 | Synthesis | Orchestrator | Both | Merge, deduplicate, resolve disagreements, produce final report |
+| 4 | Post to GitHub | Orchestrator | PR only | Format compact comment, present for user approval, post via `gh pr comment` on confirmation |
+
+---
+
+## Critical Rules
+
+1. **Claude and Codex are always required.** Both must succeed (non-empty output) or the pipeline stops. **Gemini is required unless `--skip-gemini` is set.** When `--skip-gemini` is active, the pipeline runs in dual-model mode (Claude + Codex only) — Gemini preflight, prompt, invocation, and output validation are all skipped. There is no single-model fallback.
+2. **Prompts saved first.** Before every agent invocation, save the full prompt to `<run_dir>/prompts/`. This is the audit trail.
+3. **Parallel execution.** Phase 2 spawns Claude and Codex in parallel. Neither depends on the other's output.
+4. **Worktree-based review.** Two temporary worktrees are created from the upstream repo: a **base worktree** (upstream main) for Claude, and a **PR head worktree** for Codex (and Gemini, unless `--skip-gemini`). Claude receives the diff in its prompt and uses the base worktree for caller/callee tracing. Codex and Gemini receive the diff in their prompts and run from the PR head worktree so they can read files for additional context.
+5. **Working directory conventions:**
+   - `run_dir` = `/tmp/review-pr/<run_id>/`
+   - `run_id` format: `YYYYMMDDTHHMMSSZ-<8-hex>`
+6. **All artifacts under `run_dir`.** Prompts, reviewer outputs, synthesis -- everything goes under `run_dir`.
+7. **Fail closed.** On agent failure, empty output, or malformed results, stop and report the failure. Do not attempt to interpret broken output.
+8. **North star: regression prevention.** Every decision in this pipeline optimizes for catching changes that break existing behavior, violate contracts, or corrupt state.
+
+---
+
+## CLI Interface
+
+```
+/review-pr <arg> [options]
+```
+
+### Arguments
+
+- `<arg>` (required): One of:
+  - **PR URL** — `https://github.com/org/gastown/pull/123` → PR mode
+  - **Bare integer** — `123` → PR mode (uses current repo)
+  - **Branch name** — `ci/close-stale-needs` → Local branch mode
+
+### Options
+
+| Option | Default | Description |
+|--------|---------|-------------|
+| `--base <branch>` | auto-detect | Base branch for local branch mode. Auto-detects the best base by finding the most recent merge-base across `main`, `upstream/main`, and `origin/main`. Override with an explicit branch name. Ignored in PR mode. |
+| `--skip-gemini` | false | Run dual-model review (Claude + Codex only). Use when Gemini quota is exhausted. |
+| `--skip-synthesis` | false | Output raw reviewer findings without synthesis |
+| `--claude-only` | false | Run only Claude reviewer (degrades quality) |
+| `--codex-only` | false | Run only Codex reviewer (degrades quality) |
+| `--gemini-only` | false | Run only Gemini reviewer (degrades quality) |
+
+---
+
+## Phase 1: Context Gathering
+
+Gather all context needed to build self-contained prompts. Steps 1, 3, 4, and 5 are shared across both modes. Step 2 is mode-specific.
+
+### Step 1: Set up run directory
+
+```bash
+RUN_ID="$(date -u +%Y%m%dT%H%M%SZ)-$(openssl rand -hex 4)"
+RUN_DIR="/tmp/review-pr/$RUN_ID"
+mkdir -p "$RUN_DIR"/{prompts,outputs,context,scripts}
+```
+
+### Step 2: Gather context (mode-specific)
+
+#### PR Mode
+
+1. **Parse PR identifier** from `<arg>`. Extract owner, repo, and PR number.
+
+2. **Fetch PR metadata, diff, and file list in parallel:**
+   These three `gh` calls are independent — run them concurrently to save ~5-10s:
+   ```bash
+   gh pr view <number> --repo <owner>/<repo> \
+     --json title,body,author,baseRefName,headRefName,number,additions,deletions,changedFiles \
+     > "$RUN_DIR/context/metadata.json" &
+   METADATA_PID=$!
+
+   gh pr diff <number> --repo <owner>/<repo> \
+     > "$RUN_DIR/context/diff.patch" &
+   DIFF_PID=$!
+
+   gh pr view <number> --repo <owner>/<repo> \
+     --json files --jq '.files[].path' \
+     > "$RUN_DIR/context/files.txt" &
+   FILES_PID=$!
+
+   wait $METADATA_PID $DIFF_PID $FILES_PID
+   ```
+   If any fetch fails, stop with the appropriate error.
+
+3. **Build the PR context block** (injected into all reviewer prompts):
+
+   ```
+   ## PR Context
+
+   PR #<number>: <title>
+   Author: <author>
+   Base: <baseRefName> <- Head: <headRefName>
+   Stats: +<additions> -<deletions> across <changedFiles> files
+
+   ### Description
+   <body>
+
+   ### Changed Files
+   <file list>
+
+   ### Full Diff
+   <diff>
+   ```
+
+4. **Create upstream worktrees (CRITICAL for accurate reviews):**
+
+   Fetch both the base branch and PR head from the upstream repo. Create two worktrees:
+   - **Base worktree** (`<run_dir>/worktree/`): For Claude reviewer — checked out at base branch (upstream main). Claude gets the diff in its prompt and uses the worktree to trace callers/callees.
+   - **PR head worktree** (`<run_dir>/worktree-pr/`): For Codex and Gemini reviewers — checked out at PR head. Both receive the diff in their prompts and can read files from this worktree for additional tracing.
+
+   ```bash
+   # Base worktree (for Claude)
+   # IMPORTANT: Do NOT use --depth=1. The local clone may already be shallow.
+   git fetch https://github.com/<owner>/<repo>.git <baseRefName>
+   git worktree add <run_dir>/worktree FETCH_HEAD --detach
+
+   # PR head worktree (for Codex and Gemini)
+   git fetch https://github.com/<owner>/<repo>.git +pull/<number>/head:refs/tmp/review-pr-head
+   git worktree add <run_dir>/worktree-pr refs/tmp/review-pr-head --detach
+   ```
+
+   - Both worktrees are cleaned up after synthesis.
+   - **Why this matters:** In PR #1288, reviewers flagged `router.go` sites as unmigrated because they were reading the local checkout, which was behind upstream main. The upstream worktree eliminates this class of false positive entirely.
+   - **Premise validation lesson (PR #1648, reverted in #1656):** Both Claude and Codex validated PR #1648's fix without verifying the bug existed. The PR claimed `ForceCloseWithReason` writing to a polecat branch would cause stuck HOOKED beads via merge conflicts. In reality, `MergePolecatBranch` already handles this conflict via `--theirs` resolution (polecat wins). The fix was reverted because it bypassed branch isolation unnecessarily. **Root cause:** reviewers validated the solution's internal consistency without tracing the existing conflict resolution path. All reviewer prompts now include explicit premise-validation guidance.
+   - If `git worktree add` fails (e.g., FETCH_HEAD conflict), fall back to:
+     ```bash
+     git fetch https://github.com/<owner>/<repo>.git +<baseRefName>:refs/tmp/review-base
+     git worktree add <run_dir>/worktree refs/tmp/review-base --detach
+     # Cleanup ref after worktree removal: git update-ref -d refs/tmp/review-base
+     ```
+
+#### Local Branch Mode
+
+1. **Verify branch exists:**
+   ```bash
+   git rev-parse --verify <branch>
+   ```
+   If this fails, stop: `"Branch '<branch>' not found in local repository."`
+
+2. **Resolve the effective base (CRITICAL for fork-based workflows):**
+
+   When working in a fork, the local `main` branch tracks `origin/main` (the fork), not `upstream/main` (the source repo). If the feature branch was created from `upstream/main`, using local `main` as the base produces a massive diff with hundreds of unrelated files from the fork's divergence.
+
+   **If `--base` was explicitly provided**, use it directly — the user knows what they want.
+
+   **If `--base` was NOT provided (auto-detect mode)**, find the best base automatically:
+
+   ```bash
+   # Fetch upstream to ensure refs are current
+   git fetch upstream main 2>/dev/null || true
+
+   # Collect candidate base refs
+   CANDIDATES=""
+   for ref in main upstream/main origin/main; do
+     if git rev-parse --verify "$ref" >/dev/null 2>&1; then
+       CANDIDATES="$CANDIDATES $ref"
+     fi
+   done
+
+   if [ -z "$CANDIDATES" ]; then
+     echo "ERROR: No base branch found. Tried: main, upstream/main, origin/main"
+     exit 1
+   fi
+
+   # Find the most recent merge-base (closest ancestor to the branch).
+   # The right base is the one whose merge-base with the branch is most recent,
+   # because that's where the branch actually diverged from.
+   BEST_BASE=""
+   BEST_MB=""
+   BEST_MB_TIME=0
+   for ref in $CANDIDATES; do
+     MB=$(git merge-base "$ref" <branch> 2>/dev/null) || continue
+     MB_TIME=$(git log -1 --format=%ct "$MB")
+     if [ "$MB_TIME" -gt "$BEST_MB_TIME" ]; then
+       BEST_MB_TIME=$MB_TIME
+       BEST_MB=$MB
+       BEST_BASE=$ref
+     fi
+   done
+
+   EFFECTIVE_BASE="$BEST_BASE"
+   ```
+
+   Report which base was selected:
+   ```
+   [review-pr]   Auto-detected base: <EFFECTIVE_BASE> (merge-base: <BEST_MB short>)
+   ```
+
+   If the auto-detected base differs from `main`, this means the branch was forked from a different ref (typically `upstream/main` in a fork workflow).
+
+3. **Verify commits exist between base and branch:**
+   ```bash
+   git log --oneline <EFFECTIVE_BASE>..<branch>
+   ```
+   If empty, stop: `"No commits between '<EFFECTIVE_BASE>' and '<branch>'. Nothing to review."`
+
+4. **Compute context locally:**
+   ```bash
+   # Full diff (three-dot uses merge-base automatically)
+   git diff <EFFECTIVE_BASE>...<branch>
+
+   # Diff stats
+   git diff --stat <EFFECTIVE_BASE>...<branch>
+
+   # Changed file list
+   git diff --name-only <EFFECTIVE_BASE>...<branch>
+
+   # Title (last commit subject)
+   git log -1 --format=%s <branch>
+
+   # Description (all commit messages between base and branch)
+   git log --reverse --format="* %s%n%n%b" <EFFECTIVE_BASE>..<branch>
+
+   # Author
+   git log -1 --format="%an" <branch>
+   ```
+
+5. **Build the context block** (same structure, different header):
+
+   ```
+   ## Review Context
+
+   Branch: <branch> (vs <EFFECTIVE_BASE>)
+   Author: <author>
+   Stats: +<additions> -<deletions> across <changedFiles> files
+
+   ### Description
+   <commit messages>
+
+   ### Changed Files
+   <file list>
+
+   ### Full Diff
+   <diff>
+   ```
+
+6. **Create local worktrees** (no fetch needed):
+   ```bash
+   # Base worktree (for Claude) — use the merge-base commit for the most accurate "before" state
+   git worktree add <run_dir>/worktree <EFFECTIVE_BASE> --detach
+
+   # Branch head worktree (for Codex and Gemini)
+   git worktree add <run_dir>/worktree-pr <branch> --detach
+   ```
+   - If `git worktree add` fails, report error — review cannot proceed without accurate codebase access.
+
+### Step 3: Save context
+
+Save the context block to `<run_dir>/context/pr-context.md`.
+
+### Step 4: Write PTY wrapper scripts
+
+Write to `<run_dir>/scripts/` (see Agent Invocations below):
+- `aimux-claude.sh` — PTY wrapper for Claude invocations
+- `aimux-codex.sh` — PTY wrapper for Codex invocations
+- `aimux-gemini.sh` — PTY wrapper for Gemini invocations (skip if `--skip-gemini`)
+
+### Step 5: Pre-flight check (parallel)
+
+Verify required agents are available. All preflight checks are independent — run them concurrently to save ~20-30s:
+```bash
+echo "Reply ONLY with: ok" > <run_dir>/prompts/preflight_claude.md
+echo "Reply ONLY with: ok" > <run_dir>/prompts/preflight_codex.md
+
+bash <run_dir>/scripts/aimux-claude.sh <run_dir>/prompts/preflight_claude.md /tmp/claude_preflight.txt &
+CLAUDE_PF=$!
+
+bash <run_dir>/scripts/aimux-codex.sh <run_dir>/prompts/preflight_codex.md /tmp/codex_preflight.txt &
+CODEX_PF=$!
+
+# Skip Gemini preflight if --skip-gemini
+if [ "$SKIP_GEMINI" != "true" ]; then
+  echo "Reply ONLY with: ok" > <run_dir>/prompts/preflight_gemini.md
+  bash <run_dir>/scripts/aimux-gemini.sh <run_dir>/prompts/preflight_gemini.md /tmp/gemini_preflight.txt &
+  GEMINI_PF=$!
+fi
+
+# Wait for all preflight checks
+if [ "$SKIP_GEMINI" = "true" ]; then
+  wait $CLAUDE_PF $CODEX_PF
+else
+  wait $CLAUDE_PF $CODEX_PF $GEMINI_PF
+fi
+
+# Validate all required preflights succeeded (non-empty output)
+cat /tmp/claude_preflight.txt
+cat /tmp/codex_preflight.txt
+if [ "$SKIP_GEMINI" != "true" ]; then
+  cat /tmp/gemini_preflight.txt
+fi
+```
+If any required agent fails, stop: `"Required agent <name> is not available. Check aimux status."`
+
+---
+
+## Phase 2: Parallel Review
+
+Build prompts, save them, then invoke all three reviewers in parallel. The process is identical for both modes — only the context block header differs (PR mode: `PR #<number>: <title>`, local branch mode: `Branch: <branch> (vs <base>)`).
+
+### Step 2a: Build Prompts
+
+**Claude prompt** — full context including diff (Claude receives the diff in-prompt):
+1. The claude-reviewer role prompt (see Reviewer Prompts below)
+2. The full PR context block from Phase 1 (metadata + diff)
+Save to: `<run_dir>/prompts/claude-reviewer.md`
+
+**Codex prompt** — full context including diff (same as Claude):
+1. The codex-reviewer role prompt (see Reviewer Prompts below)
+2. The full PR context block from Phase 1 (metadata + diff)
+Save to: `<run_dir>/prompts/codex-reviewer.md`
+
+**Gemini prompt** (skip if `--skip-gemini`) — full context including diff (same as Claude/Codex):
+1. The gemini-reviewer role prompt (see Reviewer Prompts below)
+2. The full PR context block from Phase 1 (metadata + diff)
+Save to: `<run_dir>/prompts/gemini-reviewer.md`
+
+> **Why `exec` with prompt, not `exec review --base`?** (Updated 2026-02-13):
+> - `--base` and `[PROMPT]` are **mutually exclusive** (confirmed: Codex returns error `the argument '--base <BRANCH>' cannot be used with '[PROMPT]'`).
+> - `exec review --base` consistently spends all capacity on codebase research (reading files, tracing callers) without producing a final review. The diff is included in the prompt so Codex doesn't need to compute it.
+> - This also eliminates the shallow clone / `git merge-base` failure that plagued `--base`.
+
+### Step 2b: Invoke in Parallel
+
+All reviewers use PTY wrapper scripts for output capture. Claude runs from the base worktree. Codex (and Gemini, unless `--skip-gemini`) run from the PR head worktree. All can read files from their respective worktrees for caller/callee tracing.
+
+```bash
+BASE_WORKTREE="<run_dir>/worktree"
+PR_WORKTREE="<run_dir>/worktree-pr"
+
+# Claude (via PTY wrapper) -- run in background from BASE worktree
+cd "$BASE_WORKTREE" && bash <run_dir>/scripts/aimux-claude.sh \
+  <run_dir>/prompts/claude-reviewer.md \
+  <run_dir>/outputs/claude-review.md &
+CLAUDE_PID=$!
+
+# Codex (via PTY wrapper) -- run in background from PR HEAD worktree.
+cd "$PR_WORKTREE" && bash <run_dir>/scripts/aimux-codex.sh \
+  <run_dir>/prompts/codex-reviewer.md \
+  <run_dir>/outputs/codex-review.md &
+CODEX_PID=$!
+
+# Gemini (via PTY wrapper) -- skip if --skip-gemini
+if [ "$SKIP_GEMINI" != "true" ]; then
+  cd "$PR_WORKTREE" && bash <run_dir>/scripts/aimux-gemini.sh \
+    <run_dir>/prompts/gemini-reviewer.md \
+    <run_dir>/outputs/gemini-review.md &
+  GEMINI_PID=$!
+fi
+
+# Wait for all reviewers
+if [ "$SKIP_GEMINI" = "true" ]; then
+  wait $CLAUDE_PID $CODEX_PID
+else
+  wait $CLAUDE_PID $CODEX_PID $GEMINI_PID
+fi
+```
+
+### Step 2c: Validate Outputs
+
+- `<run_dir>/outputs/claude-review.md` must be non-empty.
+- `<run_dir>/outputs/codex-review.md` must be non-empty.
+- `<run_dir>/outputs/gemini-review.md` must be non-empty (skip check if `--skip-gemini`).
+- If any required output is empty, report failure and stop.
+
+---
+
+## Phase 3: Synthesis
+
+Read all three review outputs and produce the final report.
+
+### Steps
+
+1. **Read** all reviewer outputs (2 if `--skip-gemini`, otherwise 3).
+2. **Build synthesis prompt** by concatenating:
+   - The synthesizer prompt (see below). If `--skip-gemini`, use the dual-model variant (see [Dual-Model Synthesizer Adjustments](#dual-model-synthesizer-adjustments) below).
+   - The PR context block **without the diff** — only metadata (title, author, base/head, stats, description) and the changed file list. The synthesizer merges findings; it doesn't need the raw diff.
+   - All reviewer outputs (labeled: "## Codex Reviewer Findings", "## Claude Reviewer Findings", and — unless `--skip-gemini` — "## Gemini Reviewer Findings")
+3. **Save** to `<run_dir>/prompts/synthesizer.md`.
+4. **Invoke Claude** for synthesis (Claude is better at reasoning-heavy merge tasks):
+   ```bash
+   bash <run_dir>/scripts/aimux-claude.sh \
+     <run_dir>/prompts/synthesizer.md \
+     <run_dir>/outputs/synthesis.md
+   ```
+5. **Clean up worktrees:**
+   ```bash
+   git worktree remove <run_dir>/worktree --force 2>/dev/null || true
+   git worktree remove <run_dir>/worktree-pr --force 2>/dev/null || true
+   # Clean up temporary refs (PR mode only — local branch mode has no temp refs):
+   git update-ref -d refs/tmp/review-base 2>/dev/null || true
+   git update-ref -d refs/tmp/review-pr-head 2>/dev/null || true
+   ```
+6. **Present** the synthesis to the user.
+
+---
+
+## Phase 4: Post to GitHub (PR Mode Only)
+
+**Local branch mode: Phase 4 is skipped entirely. Present the synthesis directly as the final output.**
+
+After presenting the synthesis to the user (PR mode), **format the GitHub comment and present it for user approval before posting**.
+
+### Pre-Comment Presentation
+
+Before showing the formatted comment, present a concise decision stanza:
+
+```
+# PR Review: <title> (#<number>)
+
+## Decision: <approve|take-the-good|request_changes|block>
+
+<1-3 sentence plain-English summary of the PR quality and key takeaways from the review. State the decision rationale.>
+
+**Salvage path:** [if take-the-good] WE adopt + apply fixups + merge — name which findings we fix and why no author input is needed.
+
+**Fixes Validated:** [if applicable]
+- <fix description>: correct/incomplete/wrong
+
+**New Findings:** [only issues WITH the PR, not bugs the PR fixes]
+1. **<Severity> (<confidence> confidence, <source(s)>):** <one-line summary>
+[repeat for each NEW finding]
+```
+
+**IMPORTANT:** Do NOT list pre-existing bugs that the PR fixes as "findings." Those are fix validations — they confirm the PR is doing its job correctly. Only list issues that the PR introduces or leaves unaddressed as findings.
+
+Then show the full formatted GitHub comment (below) in a blockquote so the user can read exactly what will be posted.
+
+End with: `Want me to post this as-is, or would you like to edit anything first?`
+
+Only post via `gh pr comment` after the user explicitly confirms. If the user requests edits, incorporate them and re-present for approval.
+
+### GitHub Comment Format
+
+The comment must follow this exact structure. The tone is **friendly, inclusive, and encouraging** — we want contributors to feel appreciated and motivated to iterate.
+
+```markdown
+## Automated PR Review — <MODE_LABEL>
+
+Where `<MODE_LABEL>` is:
+- Triple-model: `Triple-Model (Claude + Codex + Gemini)`
+- Dual-model (`--skip-gemini`): `Dual-Model (Claude + Codex)`
+
+### Decision: <approve | take-the-good | request_changes | block>
+
+<opening paragraph: 2-3 sentences thanking the contributor for the work, acknowledging the problem is real and worth solving, and noting what's good about the approach. Then 1-2 sentences summarizing the key takeaways from the review — the decision rationale. Be genuine, not formulaic.>
+
+[If there are new findings that need response:]
+Please address the items below and re-submit — not all may require changes depending on your read of the severity.
+
+---
+
+[For bug-fix PRs, optionally include a brief validation section:]
+### Fixes Validated
+- **<fix description>:** Confirmed correct. <1-sentence explanation of why the fix is right.>
+[repeat for each validated fix — keep these brief, 1-2 lines each]
+
+---
+
+[Then list ONLY new findings — issues with the PR itself, NOT pre-existing bugs it fixes:]
+
+### <Severity>: <One-line title>
+**Source:** <codex|claude|gemini|claude+codex|claude+gemini|codex+gemini|all>, <confidence> confidence
+
+<2-4 sentence explanation of the issue in plain language. No jargon walls. Explain the concrete failure scenario.>
+
+**Suggested fix:** <concrete action>
+
+[repeat for each NEW finding, ordered by severity: blocker → major → minor → nit]
+
+---
+
+### Pre-Merge Checklist
+- [ ] <derived from NEW findings only>
+
+---
+_🤖 Generated by automated review pipeline (<MODEL_LIST>)_
+
+Where `<MODEL_LIST>` is:
+- Triple-model: `Claude Opus 4.6 + GPT-5.3 Codex + Gemini 3 Pro`
+- Dual-model (`--skip-gemini`): `Claude Opus 4.6 + GPT-5.3 Codex`
+```
+
+### Format Rules
+
+1. **Compact, not verbose.** Each finding is one `###` heading + a short paragraph + suggested fix. No nested bullet lists or taxonomy tables in the comment — those stay in the raw synthesis.
+2. **Severity in the heading.** Use `Blocker:`, `Major:`, `Minor:`, or `Nit:` as the heading prefix so the contributor can quickly scan priority.
+3. **Source and confidence inline.** Put `**Source:** all, high confidence` on a single line under the heading — no taxonomy IDs or category numbers.
+4. **Plain language.** Explain *what breaks* and *when*, not abstract category names. The contributor may not know gastown internals.
+5. **No "No Finding" sections.** Only list things that need attention. Clean categories are omitted.
+6. **Encourage response.** The opening paragraph must ask the contributor to respond with their intention (fix/defer/disagree) for each item. Not all findings are necessarily blocking — the contributor's judgment matters.
+7. **Friendly closer.** End with the robot emoji footer attributing the pipeline.
+8. **Fix validations are NOT findings.** For bug-fix PRs, pre-existing bugs that the PR correctly fixes go in a brief "Fixes Validated" section — NOT as severity-tagged findings. This prevents the confusing situation where a bug-fix PR appears to have "blockers" that are actually the bugs it's fixing. Only list new issues (things the PR introduces or leaves unaddressed) as findings.
+
+### Tone Guidelines
+
+- **Thank first.** Always open by thanking the contributor and acknowledging the value of their work.
+- **Affirm the approach.** Note what's good about the direction before listing concerns.
+- **Collaborative, not gatekeeping.** Frame findings as "things to consider" not "things you got wrong." Use "suggested fix" not "required fix" in the comment (even if the synthesis says "required").
+- **Invite dialogue.** Make it clear the contributor can push back — severity ratings are the reviewers' judgment, not gospel.
+- **Encourage future contributions.** The tone should make someone want to come back and submit more PRs, not dread the review process.
+

+
+## Agent Invocations
+
+### Claude PTY Wrapper (REQUIRED)
+
+**Claude CLI requires a TTY** to produce output. When stdout is a plain file or pipe, it hangs silently with 0 bytes. All Claude invocations MUST use the PTY wrapper script.
+
+**Critical environment fixes (learned 2026-02-13):**
+- **`unset CLAUDECODE`** — Claude Code refuses to launch inside another Claude Code session (detects via `CLAUDECODE` env var). The `script` PTY inherits the parent environment, so nested invocations fail with "cannot be launched inside another Claude Code session." Unsetting this var in the `script -c` command fixes it.
+- **`command cat`** — On some systems `cat` is aliased to `bat`, which adds ANSI formatting that corrupts the pipe to aimux. Using `command cat` bypasses aliases.
+
+**Stream-JSON output format (learned 2026-02-13):**
+- Claude's `--output-format stream-json` produces TWO different event formats depending on whether Claude uses tools:
+  - **No tool use:** `stream_event` events with `content_block_delta` / `text_delta` — the original parser handled this.
+  - **Multi-turn with tool use:** `assistant` events with `message.content[].text` — each assistant turn is a separate event containing the full text for that turn. The review content is in the longest text block that contains `##` markers.
+- The parser MUST handle both formats. Extract text from `assistant` events as a fallback when `stream_event` deltas are empty.
+
+Write this to `<run_dir>/scripts/aimux-claude.sh` during Phase 1:
+
+```bash
+#!/usr/bin/env bash

+
+Make executable: `chmod +x <run_dir>/scripts/aimux-claude.sh`
+
+### Codex PTY Wrapper (REQUIRED)
+
+**Codex `exec -o` does NOT work for large review prompts.** Codex spends its capacity on file reads and reasoning, then exits without producing a final agent message — so the `-o` file is never written. This was verified across multiple runs on PR #1226 (83KB+ prompt). The fix is PTY capture via `script`, same pattern as Claude.
+
+**Key design decisions (verified 2026-02-13):**
+- Use `exec` (not `exec review --base`). The `--base` subcommand spends all capacity on codebase research without producing a final review.
+- **Must use `--dangerously-bypass-approvals-and-sandbox`** — without this, Codex runs in read-only sandbox and cannot execute commands for caller/callee tracing.
+- **Must use PTY capture** (not `-o` flag) — the `-o` flag only captures the "last agent message", but Codex never produces one for large prompts. PTY capture gets all output including intermediate "codex" blocks.
+- Include the full diff in the prompt so Codex doesn't need to compute it.
+- Use `-c model_reasoning_effort='"xhigh"'` for maximum reasoning depth.
+- Pipe the prompt via `cat <file> | ... -- -` (not stdin redirect `-- - < file`).

+
+> **Historical note (2026-02-13):** The original approach used `codex exec -o <file>` to capture the last agent message. This worked for small prompts but consistently failed for large review prompts (83KB+). Codex would read 6+ files, produce brief progress messages, and exit (code 0) without a final agent message — so `-o` never wrote the file. The PTY capture approach (matching Forge's `agent-wrapper.sh` pattern) captures all output and extracts the review from "codex" blocks. The `--dangerously-bypass-approvals-and-sandbox` flag is required for Codex to execute commands for caller/callee tracing.
+
+### Gemini PTY Wrapper (REQUIRED)
+
+**Gemini is invoked via `aimux run gemini`**, matching the pattern used for Claude and Codex. Aimux handles account selection and sets `GEMINI_CLI_HOME` for credential isolation. The Gemini CLI uses `--yolo` for auto-approving tool use (file reads for tracing), `-p ''` for headless (non-interactive) mode with stdin as input, and `-o text` for plain text output. The output extraction is simpler than Claude/Codex — just strip ANSI and script chrome (no JSON parsing, no "codex block" extraction).

+All three reviewers use this exact category taxonomy and priority ranking:
+
+| Priority | # | Category | Why it catches regressions |
+|----------|---|----------|---------------------------|
+| P0 | 1 | Behavioral Correctness | Logic bugs, edge cases, off-by-ones, nil derefs |
+| P0 | 2 | Contract & Interface Fidelity | Broken caller expectations, schema violations |
+| P0 | 3 | Change Impact / Blast Radius | Incomplete updates across callsites |
+| P0 | 4 | Concurrency, Ordering & State Safety | Races, deadlocks, ordering violations |

+## Reviewer Prompts
+
+### codex-reviewer
+
+This prompt is passed to Codex via PTY-wrapped `exec` along with the full context block (metadata + diff). Codex runs from the head worktree (PR head or branch tip) and can read files for additional caller/callee tracing.
+
+```
+You are "codex-reviewer" for a code review in the gastown codebase.
+
+Gastown is a Go-based multi-agent orchestration system. It manages concurrent AI agents across tmux sessions, git worktrees, and a bead-based work tracking system. Regressions are hard to catch because the system is difficult to test end-to-end.
+
+## Mission
+
+Produce a high-signal, evidence-first review focused on concrete code impact and repo-wide traceability. Your strength is indexing and tracing -- use it. Find every caller, every test, every contract touchpoint.
+
+IMPORTANT: You MUST produce a final review with findings. Do NOT spend all your time reading files. The diff below contains all changed code. Focus your analysis on the diff itself. Only read files from the worktree if you need to check a specific caller or contract — DO NOT read more than 5 files total.
+
+## Category Taxonomy (use exactly)

+7) Resource Lifecycle & Cleanup
+8) Release Safety
+9) Test Evidence Quality
+10) Architectural Consistency

+Priority: P0 = categories 1-4 (aggressively check). P1 = 5-8. P2 = 9-11.
+
+## How to Work
+
+### Codebase Access
+You are running from a git worktree checked out at the PR head. The full diff is included in this prompt. You may use the codebase to trace callers and verify claims, but **prioritize analyzing the diff directly** over exhaustive codebase research. The diff contains all changed code — focus your analysis there.
+
+### General
+- Analyze the diff for logic bugs, edge cases, and incomplete updates.
+- Identify contract touchpoints: CLI flags, API signatures, config structs, TOML schemas, hook protocols, bead fields.
+- Check that updates are complete across all usage sites visible in the diff.
+- Map changed behavior to existing tests and list explicit coverage gaps.
+- Check cleanup paths (files, tmux sessions, worktrees, goroutines) on both success AND failure.
+- Check that error messages and log output remain useful for debugging.
+
+### Existing Handling Check (CRITICAL for bug-fix PRs)
+- When a PR claims to fix a failure mode, **actively search for existing code that already handles that failure.** This is your highest-priority tracing task for bug-fix PRs.
+- Specifically search for: error recovery paths, retry logic, conflict resolution, fallback branches, and any multi-phase handling (try → detect failure → resolve) downstream of the "broken" code path.
+- If you find an existing handling mechanism, evaluate whether it would resolve the claimed bug WITHOUT the PR's changes. Cite the handler with path:line evidence.
+- For Dolt/database operations: always trace merge conflict resolution paths (`--theirs`, `--ours`, `DOLT_CONFLICTS_RESOLVE`). These are specifically designed to handle divergent branch state.
+- Include your findings in the Evidence Bundle under a new field: **Existing handlers checked:** [list with path:line, or "none found"]
+
+### Gastown-Specific Invariants
+- **Formula TOML contracts:** Step dependencies must form a DAG. No orphan steps. Variable references (Go text/template) must resolve. New steps must appear in TopologicalSort output.
+- **Role boundaries:** Polecats never touch main branch. Refinery never creates worktrees. Deacon never merges. Witness never does implementation work. Mayor never spawns polecats directly.
+- **Hook/bead protocol:** `gc bd ready`/`gc bd close` must be paired. Bead sync must happen before `gt done`. Hook environment variables must be set before agent spawn.
+- **Agent preset contracts:** `AgentPresetInfo` fields (SessionIDEnv, ResumeFlag, ResumeStyle, SupportsHooks) must match actual CLI behavior of the agent binary.
+- **Self-cleaning contract:** Polecats must call `gt done` which syncs beads, nukes worktree, and exits. No partial cleanup.
+- **Tmux session management:** Session names must be deterministic. Pane targeting must handle "no sessions" and "no current target" errors.
+
+## Output Format
+
+**CRITICAL: Separate fix validations from new findings.**
+
+Bug-fix PRs will have two classes of observations:
+1. **Fix Validations** — pre-existing bugs that the PR correctly fixes. These are NOT problems with the PR. List them to confirm correctness, but they do NOT count as findings.
+2. **New Findings** — issues introduced by the PR itself, or remaining issues that the PR should address. These ARE problems with the PR.
+
+Start with "## Fix Validations" (if the PR fixes bugs):
+```
+### <what was broken>
+- **Status:** correct | incomplete | wrong
+- **Evidence:** path:line
+- **Assessment:** [1-2 sentences confirming the fix is correct, or explaining why it's incomplete/wrong]
+```
+
+Then "## Findings" for NEW issues only:
+
+For each finding:
+```
+### [Category Name]
+- **Severity:** blocker|major|minor|nit
+- **Confidence:** high|medium|low
+- **Evidence:** path:line[, path:line]
+- **Why it matters:** [one sentence]
+- **Suggested fix:** [concrete action]
+```
+
+Then "## No Finding" for categories with no issues (list them explicitly).
+
+End with:
+## Evidence Bundle
+- **Changed hot paths:** [list]
+- **Impacted callers:** [list with path:line]
+- **Impacted tests:** [list with path:line]
+- **Unresolved uncertainty:** [list]
+
+## Constraints
+- No style/formatting issues unless they create behavioral risk.
+- No invented behavior -- cite code evidence for every claim. **Search the codebase** to back up claims about callers, patterns, or missing migrations.
+- Prefer precise path:line references over broad claims.
+- Fewer high-signal findings >> exhaustive speculative lists.
+- **Do NOT list pre-existing bugs that the PR fixes as "findings".** Those go under Fix Validations.

+
+## How to Work
+
+### Codebase Access
+You are running from a git worktree checked out at the base branch, which represents the authoritative codebase state before the changes. Use your tools (grep, find, read) freely to trace callers, callees, dependencies, and existing patterns. The diff is included in the prompt below — the worktree shows the codebase *before* the changes.
+
+### General
+- Evaluate whether implementation matches claimed PR intent. Flag divergence.
+- Check edge cases: empty inputs, nil values, zero-length slices, missing map keys, EOF, partial writes.
+- Check negative paths: what happens when the operation fails halfway? Is state left consistent?
+- Validate ordering assumptions under concurrent execution. If two goroutines or agents could race on shared state, flag it.
+- Inspect contract safety: backward compatibility of exported functions, schema/protocol stability, caller expectations preserved. **Search the codebase** to find callers of changed functions.
+- Threat-model trust boundaries: user input → exec.Command, file paths → os.Open, template data → TOML injection.
+- Assess rollback safety: could this change be reverted cleanly? Does it introduce persistent state that survives rollback?
+- Check operational diagnosability: if this change breaks in production, can you tell what happened from logs and bead state?
+
+### Premise Validation (CRITICAL for bug-fix PRs)
+- **Before validating a fix, validate the bug.** If the PR claims "X causes Y failure", trace the full execution path to verify Y actually occurs without this PR. Do NOT take the PR description's failure narrative at face value.
+- Search for existing handling mechanisms downstream: error recovery, conflict resolution (e.g., `--theirs` merge strategies), retry logic, fallback paths. The codebase may already handle the failure through a different code path that the PR author missed.
+- Ask: "If I remove this entire PR, does the claimed failure actually happen?" Trace end-to-end, across files.
+- Flag if the PR bypasses an existing mechanism (e.g., writing directly to a data store instead of going through the established merge/conflict-resolution pipeline). Even if the bypass "works", it breaks architectural contracts.
+- When you cannot fully verify the premise, mark the Fix Validation as `incomplete` with a note explaining what you couldn't trace, rather than defaulting to `correct`.
+
+### Gastown-Specific Invariants
+- **Formula TOML contracts:** Step dependencies must form a DAG. No orphan steps. Variable references (Go text/template) must resolve. Changed steps must not break TopologicalSort or ReadySteps computation.
+- **Role boundaries:** Polecats never touch main. Refinery never creates worktrees. Deacon never merges. Witness never implements. Mayor never spawns polecats directly. Violations are silent and catastrophic.
+- **Hook/bead protocol:** `gc bd ready`/`gc bd close` pairing. Bead sync before `gt done`. Hook env vars set before agent spawn. Violation means lost work or phantom state.
+- **Agent preset contracts:** `AgentPresetInfo` fields must match real CLI behavior. Wrong ResumeStyle = broken session resume. Wrong SupportsHooks = silent hook failure.
+- **Self-cleaning contract:** Polecats call `gt done` → sync beads → nuke worktree → exit. Partial cleanup leaves zombie worktrees that corrupt future operations.
+- **Tmux session management:** Session names deterministic. Pane targeting handles edge cases. Race between session creation and pane targeting is a known fragile area.
+- **Merge queue (Refinery):** Only Refinery merges to main. Merge ordering must respect dependency graph. Conflict resolution spawns fresh polecats, never retries in-place.

+You are "gemini-reviewer" for a code review in the gastown codebase.
+
+Gastown is a Go-based multi-agent orchestration system. It manages concurrent AI agents across tmux sessions, git worktrees, and a bead-based work tracking system. Regressions are hard to catch because the system is difficult to test end-to-end.
+
+## Mission
+
+Produce a high-signal review focused on cross-file consistency, pattern adherence, and architectural coherence. Your strength is analyzing how changes ripple across files and whether the codebase remains internally consistent after the PR. Think holistically — zoom out from individual lines to the structural relationships between components.
+
+Two other reviewers (Claude and Codex) are analyzing this same PR in parallel. Claude focuses on invariant safety and edge-case reasoning. Codex focuses on caller/callee tracing and evidence gathering. Your job is to catch what they'll miss: **pattern drift, incomplete propagation, architectural violations, and cross-cutting inconsistencies.**

+
+## How to Work
+
+### Codebase Access
+You are running from a git worktree checked out at the PR head — the code as it will look after the change. Use your tools freely to read files, search for patterns, and trace dependencies. The diff is included in the prompt below.
+
+### Your Unique Focus Areas
+
+**Cross-file consistency (your #1 job):**
+- When the PR changes a struct, interface, or function signature: search the entire codebase for all usage sites. Are all callers updated? Are there test files, mock implementations, or generated code that need matching changes?
+- When the PR adds a new pattern (new helper function, new error type, new config field): does it follow the conventions established by similar existing patterns? Search for 2-3 analogous examples and compare.
+- When the PR modifies one file in a group of related files (e.g., one role's manager but not others): check whether sibling files need parallel changes.
+
+**Pattern drift detection:**
+- Compare the PR's approach against the dominant pattern in the codebase. If 8 out of 10 similar functions use pattern A and the PR introduces pattern B, flag it — even if B works. Consistency has value.
+- Look for copy-paste with incomplete adaptation: when code is clearly modeled on an existing function, check that ALL relevant differences were addressed (not just the obvious ones).
+
+**Dependency chain analysis:**
+- Map the chain: what calls the changed code, and what does the changed code call? Follow the chain 2-3 levels deep. Are there intermediate functions that make assumptions the PR violates?
+- Check for implicit contracts: does the changed code produce output that downstream consumers parse or depend on? (Log formats, bead field values, tmux session name patterns, file path conventions.)
+
+**Architectural coherence:**
+- Does the change respect the system's layering? (e.g., CLI layer should not import internal agent logic; role managers should not reach into each other's state.)
+- Does the change create new coupling between modules that were previously independent?
+- Does the change duplicate logic that already exists elsewhere? If so, should it call the existing code instead?
+
+**Bypass detection (critical for bug-fix PRs):**
+- When a PR changes the ordering or location of an operation to avoid a failure, check whether the existing code path already has a mechanism to handle that failure (conflict resolution, retry, fallback).
+- Flag PRs that bypass established data flow (e.g., writing directly to main instead of going through branch merge + conflict resolution). Even if the bypass "works", it violates the system's designed error-handling pipeline.
+- Compare the PR's approach against the system's designed multi-phase patterns. If the system has a deliberate try → conflict → resolve pipeline, and the PR avoids the conflict entirely rather than relying on the resolution phase, that's an architectural red flag worth investigating.
+
+### Gastown-Specific Patterns to Check
+- **Role boundary compliance:** Polecats never touch main. Refinery never creates worktrees. Deacon never merges. Mayor never spawns polecats directly. Check that the PR doesn't introduce cross-role coupling.
+- **Formula consistency:** If a formula TOML is changed, verify step IDs, dependency edges, and description fields are consistent with the formula's Go consumer code.
+- **Bead field conventions:** Bead labels follow `key:value` format. Status transitions follow open → closed. Description fields use consistent Markdown structure.
+- **Config/flag propagation:** When a new CLI flag or config field is added, check that it's wired through all layers: CLI parsing → config struct → runtime usage → help text → documentation.
+- **Error message consistency:** Gastown uses structured error wrapping (`fmt.Errorf("context: %w", err)`). Check that new error messages follow this pattern and don't lose error context.
+- **Logging conventions:** Check that new log output includes enough context (session name, bead ID, step ID) to diagnose issues without additional debugging.
+
+## Output Format
+
+**CRITICAL: Separate fix validations from new findings.**
+
+Bug-fix PRs will have two classes of observations:
+1. **Fix Validations** — pre-existing bugs that the PR correctly fixes. These are NOT problems with the PR.
+2. **New Findings** — issues introduced by the PR itself, or remaining issues the PR should address.
+
+Start with "## Fix Validations" (if the PR fixes bugs):
+### <what was broken>
+- **Status:** correct | incomplete | wrong
+- **Evidence:** path:line
+- **Assessment:** [1-2 sentences]

+
+### [Category Name]
+- **Severity:** blocker|major|minor|nit
+- **Confidence:** high|medium|low
+- **Evidence:** path:line[, path:line]
+- **Pattern comparison:** [cite the existing pattern this deviates from, with path:line]
+- **Why it matters:** [one sentence]
+- **Suggested fix:** [concrete action]
+
+Then "## No Finding" for categories with no issues.
+
+End with:
+## Consistency Report
+- **Patterns checked:** [list patterns you searched for and verified]
+- **Sibling files checked:** [list related files you compared against]
+- **Propagation verified:** [list dependency chains you traced]
+- **Drift detected:** [list any pattern deviations, even minor ones]
+
+## Constraints
+- No style nits unless they represent pattern drift from an established codebase convention.
+- Every finding must cite a **comparison point** — the existing pattern or file it deviates from. No abstract claims.

+
+## Synthesizer Prompt
+
+```
+You are the "review-synthesizer" combining outputs from codex-reviewer, claude-reviewer, and gemini-reviewer for a gastown code review.
+
+## Inputs
+
+You will receive:
+1. The review context (metadata, description, changed file list — NOT the full diff)
+2. Codex reviewer findings
+3. Claude reviewer findings
+4. Gemini reviewer findings
+
+## Task
+
+Create one maintainer-grade decision report. Deduplicated, severity-calibrated, action-oriented.
+
+## Method
+
+1) Normalize all findings into the shared taxonomy:
+   1. Behavioral Correctness
+   2. Contract & Interface Fidelity
+   3. Change Impact / Blast Radius
+   4. Concurrency, Ordering & State Safety
+   5. Error Handling & Resilience
+   6. Security Surface
+   7. Resource Lifecycle & Cleanup
+   8. Release Safety
+   9. Test Evidence Quality
+   10. Architectural Consistency
+   11. Debuggability & Operability
+
+2) Merge findings that share the same root cause into a single entry.
+
+3) Severity disagreement policy:
+   - If multiple reviewers flag the same issue, keep the stricter severity.
+   - If one reviewer flags blocker and the others don't mention it at all, mark confidence as "medium" and keep blocker -- this needs human attention.
+   - If severity differs by exactly one level (e.g., major vs minor), keep the stricter.
+
+4) Mark each final finding with source attribution: `codex`, `claude`, `gemini`, `claude+codex`, `claude+gemini`, `codex+gemini`, or `all`.
+
+5) Cross-reference Claude's findings against Codex's evidence bundle. Findings that have concrete path:line evidence from the bundle get confidence boosted. Findings with no evidence trail get confidence reduced.
+
+6) **Trust codebase-backed evidence.** All three reviewers had full access to the upstream codebase (via worktree). Findings that cite specific path:line evidence from codebase searches are high-signal. Findings that make claims about "remaining sites" or "missing callers" without citing search evidence should be treated with lower confidence — ask whether the reviewer actually searched.
+
+7) **Gemini cross-file findings are high-signal.** When Gemini flags a cross-file consistency issue that neither Claude nor Codex mentioned, treat it as high-signal — this is Gemini's specialty. Cross-reference Gemini's consistency report against Codex's evidence bundle. Gemini findings that align with Codex-traced callers get confidence boosted.
+
+8) **Premise validation consensus check.** For bug-fix PRs: check whether any reviewer independently verified that the claimed failure actually occurs (by tracing the full execution path including existing handling mechanisms like conflict resolution or retry logic). If ALL reviewers accepted the PR's stated bug at face value without independent verification, add a finding:
+   - Category: Behavioral Correctness
+   - Severity: major
+   - Confidence: medium
+   - Source: synthesis
+   - Summary: "No reviewer independently verified the claimed failure scenario. Existing handling mechanisms (e.g., [cite if any reviewer mentioned them]) may already resolve this case."
+   This is critical because a fix for a non-existent bug adds complexity, may bypass safety mechanisms, and sets incorrect precedents. See PR #1648 (reverted in #1656).
+
+## Output Format
+
+**CRITICAL: Separate fix validations from new findings.**
+
+Reviewers may report two classes of observations:
+1. **Fix Validations** — pre-existing bugs the PR correctly fixes. These confirm the fix is correct. They do NOT count toward the merge decision.
+2. **New Findings** — issues introduced by or remaining in the PR. These drive the merge decision.
+
+When merging, classify each reviewer observation into one of these two categories. If a reviewer listed a "fix validation" as a "finding" (e.g., severity: blocker with note "this PR fixes it"), reclassify it as a fix validation.
+
+Where `<identifier>` is `#<number>` for PR mode or `<branch> vs <base>` for local branch mode.
+
+```
+# Review: <title> (<identifier>)
+
+## Decision: approve | take-the-good | request_changes | block
+
+## Fix Validations
+[For bug-fix PRs: brief confirmation that pre-existing bugs are correctly fixed]
+- **<what was broken>:** <correct|incomplete|wrong> — <1-sentence assessment>
+
+## Top Risks (max 5, ordered by severity then confidence)
+[Only NEW findings — not fix validations]
+1. [one-line summary] — severity / confidence / source
+
+## New Findings
+
+### [Category Name]
+- **Severity:** blocker|major|minor|nit
+- **Confidence:** high|medium|low
+- **Source:** codex|claude|gemini|claude+codex|claude+gemini|codex+gemini|all
+- **Evidence:** path:line
+- **Why it matters:** [one sentence]
+- **Required fix:** [concrete action]
+
+[repeat for each NEW finding]
+
+## Category Coverage
+[For each of the 11 categories: either a finding reference or "No finding"]
+
+## Pre-Merge Checklist
+- [ ] [must-pass items derived from NEW findings only]
+```
+
+## Decision Policy
+
+Decision is based ONLY on new findings, NOT on fix validations. `request_changes`
+(bouncing the PR back to the author) is the LAST resort — the default for any
+finding WE can fix is `take-the-good` (adopt the change, apply the fixups
+ourselves, merge). For each unresolved new finding, ask in order:
+
+1. **Is it a security or release-safety blocker?** (category 6 Security, or
+   category 8 Release Safety, at blocker severity) → `block`. These are the
+   only blockers that block.
+2. **Can WE fix it?** — it is reproducible AND needs no author-only input
+   (no secret/credential, no environment we can't stand up, no design intent
+   only the author knows, and `maintainerCanModify` is not false) → `take-the-good`.
+   This is the default for fixable findings at ANY severity, including blocker
+   and major correctness issues in categories 1-5, 7, 9-11.
+3. **Does it genuinely need the author?** → `request_changes`, and name the
+   reserved case: **cant-reproduce**, **needs-author-input** (secret / env /
+   design-intent / `maintainerCanModify = false`), or **author-wants-to-iterate**
+   (the author explicitly asked to own the fix).
+4. **Purely minor/nit, or no new findings at all** → `approve`.
+
+- Fix validations marked "incomplete" or "wrong" → treat as new findings at the
+  appropriate severity, then run them through the same ladder.
+- **Never `request_changes` a finding WE can fix.** If none of the three reserved
+  cases applies, the finding is ours → `take-the-good`.
+
+## Constraints
+- No style-only commentary.
+- Concise, concrete, evidence-linked.
+- The output is for a human maintainer making a merge decision. Respect their time.
+```

+
+## Dual-Model Synthesizer Adjustments
+
+When `--skip-gemini` is active, apply these adjustments to the synthesizer prompt and process:
+
+1. **Synthesizer prompt header:** Replace "combining outputs from codex-reviewer, claude-reviewer, and gemini-reviewer" with "combining outputs from codex-reviewer and claude-reviewer (dual-model mode, Gemini skipped)".
+2. **Inputs section:** Remove "3. Gemini reviewer findings" from the input list.
+3. **Method step 4:** Source attribution uses only: `codex`, `claude`, or `claude+codex` (not `gemini`, `claude+gemini`, `codex+gemini`, or `all`).
+4. **Method step 7 (Gemini cross-file findings):** Skip entirely — this step is N/A in dual-model mode.
+5. **Cross-file coverage gap:** Note in the synthesis output that cross-file consistency analysis (Gemini's specialty) was not performed. Add a line under Category Coverage: `"⚠ Cross-file consistency (category 3, 10) had reduced coverage — Gemini reviewer was skipped."`
+6. **GitHub comment heading:** Use `Dual-Model (Claude + Codex)` instead of `Triple-Model (Claude + Codex + Gemini)`.
+7. **GitHub comment footer:** Use `Claude Opus 4.6 + GPT-5.3 Codex` instead of the triple-model list.
+
+All other synthesis logic (deduplication, severity policy, decision policy, output format) remains identical.

+
+---
+
+## Error Handling
+
+| Failure | Action |
+|---------|--------|
+| `gh` command fails | Report error, check auth: `gh auth status` |
+| PR not found | Report "PR not found" with URL attempted |
+| Branch not found (local mode) | Report "Branch '<branch>' not found in local repository." |
+| Base branch not found (local mode) | Report "Base branch '<base>' not found in local repository." |
+| No commits between branches (local mode) | Report "No commits between '<base>' and '<branch>'. Nothing to review." |
+| `--base` used in PR mode | Ignore silently (base is determined by the PR) |
+| Worktree creation fails | Try fallback ref method (PR mode). If still fails, report error — review cannot proceed without accurate codebase access |
+| Agent pre-flight fails | Report which agent, suggest `aimux status` |
+| Gemini unavailable via aimux | If `--skip-gemini`: N/A. Otherwise: Report "Gemini not available. Check `aimux status` and `aimux verify gemini`.", stop |
+| One reviewer produces empty output | Report failure and stop. All required reviewers must succeed — no single-model fallback |
+| Gemini produces empty output | If `--skip-gemini`: N/A. Otherwise: Report failure, stop |
+| Codex PTY log has no "codex" blocks | Codex may have failed to start or hit an error. Check the PTY log file. Stop pipeline — all reviewers required |
+| Codex output is duplicated | Normal behavior — Codex sometimes outputs the review twice with a "tokens used" separator. The PTY parser's "longest block" heuristic handles this automatically |
+| Synthesis produces empty output | Present raw reviewer outputs directly |
+| Diff too large (>100KB) | All three reviewers get the full diff. No truncation. |
+| Worktree cleanup fails | Log warning but don't block. User can clean up manually: `git worktree list` then `git worktree remove` |
+| Claude produces tiny output (<500 bytes) | Claude spent all capacity on tool use (reading files) instead of producing a review. **Retry with shorter prompt** that includes explicit "CRITICAL: Do NOT use tools to read files" instruction. See Known Issues below |
+| Branch has large merge-base divergence | Should be auto-resolved by the base auto-detection (checks `main`, `upstream/main`, `origin/main` and picks the most recent merge-base). If auto-detection still produces a large diff, the user can override with `--base <ref>` pointing to the correct ancestor. |
+
+---
+
+## Known Issues & Operational Learnings
+
+### Claude reviewer fails on large prompts (>100KB)
+
+**Symptom:** Claude produces 100-300 bytes of output like "I'll start by searching the codebase..." instead of an actual review. This happens consistently when the prompt exceeds ~100KB and Claude has tool access.
+
+**Root cause:** Claude uses all its capacity on tool calls (reading files, grepping) and never produces the final review text.
+
+**Fix:** Use a shorter role prompt (~500 bytes vs ~4KB) with an explicit instruction: `CRITICAL: Do NOT use tools to read files. The diff contains everything you need. Produce your review directly.` This consistently produces 9-12KB reviews in ~60-180s.
+
+**When to retry:** If Claude output is <500 bytes, retry once with the short prompt. If still failing, report failure.
+
+### Local branch mode: fork-based workflows (resolved)
+
+**Symptom:** `git diff main...branch` returns hundreds of files and 70K+ lines when the branch only has ~15 feature commits.
+
+**Root cause:** In fork-based workflows, the local `main` tracks `origin/main` (the fork), not `upstream/main` (the source repo). When the feature branch was forked from `upstream/main`, `git merge-base main branch` returns a very old commit, and the three-dot diff includes all divergence between the fork's main and upstream.
+
+**Fix (implemented):** The local branch mode now auto-detects the best base by checking `main`, `upstream/main`, and `origin/main`, and picking the one with the most recent merge-base with the branch. This handles fork workflows automatically without manual intervention. Users can still override with `--base <branch>` if needed.
+
+### Codex output deduplication
+
+**Behavior:** Codex consistently produces its review output twice in the PTY log, separated by a "tokens used" line. The PTY parser's "longest block" heuristic handles this automatically — no action needed. But be aware that raw output file sizes appear ~2x larger than the actual review content.
+
+### Review iteration convergence
+
+**Pattern observed across 11 review passes:** Each review cycle fixes 3-5 findings but may introduce 1-2 new ones. Findings that persist across reviews fall into two categories:
+1. **Architecture limitations** (integration tests, stale snapshots) — these repeat every cycle and should be tracked as follow-ups rather than fixed in-loop.
+2. **Genuine new findings** from code changes made to fix previous findings — these are real and should be fixed.
+
+**Recommendation for adopt-pr-auto:** After 2-3 review iterations, categorize remaining findings as "fix now" vs "track as follow-up" rather than continuing to iterate. Convergence typically takes 2 iterations for code fixes and never resolves for architecture-level concerns.

+# profiler
+
+Retroactive profiling of Gas City formula runs. Everything works from the
+workflow root bead id against sources that are already durable — no core
+changes and no launch-time opt-in required. Proposal and motivating data:
+gastownhall/gascity#3925 (design) and gastownhall/gascity#3924 (measured
+findings from a real 3.5-hour run).
+
+Requires the `gascity` pack: `bench-nullop` routes its steps to
+`gc.run-operator`, so `profiler/pack.toml` imports `../gascity` as `gc` the
+same way the other derived packs in this repo do.
+
+## Commands
+
+```
+gc profiler collect <root-bead-id> [--rig <path>] [--out <dir>]
+gc profiler report  <root-bead-id> [--json] [--html] [--out <dir>]
+gc profiler compare <root-a> <root-b>
+```
+
+The `profiler` prefix is the city's import binding for this pack, so it follows
+whatever name the city imports it under (`[imports.profiler]` here).
+
+`collect` assembles a capture under `<city>/.gc/runtime/profiles/<root>/`:
+
+| File | Contents |
+|---|---|
+| `manifest.json` | schema (`gc.profile.capture.v1`), window, per-file hashes, disclosed gaps |
+| `beads.json` | the run's full bead closure (root, steps, drain sub-workflows, convoys) |
+| `session-beads.json` | agent session + nudge beads for the run window |
+| `events.window.jsonl.gz` | the run's slice of the durable city event log |
+| `transcripts/*.jsonl.gz` | provider transcripts resolved via session `work_dir` + `session_key` |
+| `usage.window.jsonl` | usage facts (tokens / wall / cost) for the run |
+| `formula-provenance.json` | formula identity, runtime vars, packs.lock |
+| `git.json` | commit timestamps and refs from the rig |
+
+`report` derives step spans (ready → started → closed, with dispatch waits
+computed from blocker-close times), session lanes by role, totals, a
+token/cost rollup, and findings tagged by fixable layer (`formula` / `config`
+/ `platform`). `--html` writes a self-contained page with a step Gantt and
+session lanes.
+
+A run that has not finished profiles fine. The root has no `closed_at`, so the
+report shows the run as in flight with elapsed time instead of a total, steps
+that have started but not closed render as `running`, and the time axis is
+anchored on the latest timestamp the capture observed (not on wall clock, so
+re-rendering a capture later does not move the axis).
+
+`compare` diffs two `report.json` files: total, dispatch wait, session count,
+and per-step wait/active deltas for steps whose titles match.
+
+Run `collect` from the rig root (or pass `--rig`); the root bead must be
+resolvable in that rig's store.
+
+## Agent + analysis formula
+
+`profile-analyze` (routed to the pack's `profiler.profile-analyst` role) reads a
+collected capture and writes `analysis.md` beside it: a narrative
+interpretation of the mechanical report — why the slow steps were slow,
+model-vs-tool-vs-dispatch attribution from transcripts, per-finding fixable
+layer, and concrete suggested formula edits. Launch:
+
+```
+gc sling profiler.profile-analyst profile-analyze --formula --var root=<root-bead-id>
+```
+
+## Tokens and cost
+
+Profiles cover **latency and cost**. `collect` copies the run's slice of the
+city's usage sink (`.gc/usage.jsonl`, keyed on `run_id` / `session_id`) into
+`usage.window.jsonl`, and `report` rolls those facts up per run and per step:
+input / output / cache tokens, runtime wall-seconds, model invocation count,
+and estimated USD.
+
+What that rollup does and does not mean:
+
+- Facts are deduped on `idempotency_key` before counting, because the sink
+  can legitimately re-emit one.
+- Cost is a **list-price estimate for decision support, not a charge**. Facts
+  whose `(provider, model)` pair had no price are counted as `unpriced` and
+  left out of the estimate — never treated as free. `report` prints that count
+  alongside the total, matching `gc costs`.
+- Per-step attribution joins a fact's `step_id` (a formula `gc.step_id`, not a
+  bead id) to the step bead's `gc.step_id` metadata, and only when exactly one
+  captured bead matches. Facts with no step id — ad-hoc, manual and idle
+  sessions, plus compute facts emitted after the active-work pointer is
+  cleared at teardown — count toward the run total and are reported as
+  unattributed rather than spread across candidates.
+- If the city runs with its usage provider set to `discard` or `exec:`, there
+  is no local sink to capture; `collect` records the gap and `report` says the
+  dimension is missing instead of reporting zero.
+
+## Formula
+
+`bench-nullop` — a chain of trivial steps plus a parallel fan-out that close
+immediately with no real work. Profiling a bench-nullop run measures pure
+orchestration overhead (dispatch, spawn/wake, claim, close) with zero LLM
+variance: the noise floor for `compare`, and a regression canary for
+platform latency.
+
+## Known v0 limits (disclosed in the manifest where they apply)
+
+- Events are read from the active city log only; rotated `.gz` archives are
+  not yet scanned.
+- Only Claude Code transcript layout is resolved (`~/.claude/projects`);
+  other providers fall through to a manifest gap entry.
+- Transcripts are read from the provider's own storage at collect time; this
+  pack deliberately does not back them up (profiling reads what the user's
+  existing storage holds). Sessions whose transcript files are already gone
+  are listed as manifest gaps. Durable transcript correlation is a core
+  enabler (E3 in the proposal), not pack scope.
+- Reconciler trace slices are not captured (7-day/1-GiB retention upstream).

+You interpret profile captures written by this pack's `gc profiler collect` and

+# gc profiler collect
+
+Assemble a durable profile capture for one formula run, retroactively, from
+sources that already survive. Works on any workflow root bead id — including
+runs that crashed, were never marked for profiling, or are still in flight.
+
+## Usage
+
+```bash
+gc profiler collect <root-bead-id> [--rig <path>] [--city <path>] [--out <dir>]
+```
+
+Run it from the run's rig root, or pass `--rig`; the root bead must be
+resolvable in that rig's store. Output defaults to
+`<city>/.gc/runtime/profiles/<root-bead-id>/`.
+
+## What it captures
+
+`manifest.json` (schema `gc.profile.capture.v1`) plus the run's bead closure,
+the city's session and nudge beads for the run window, the run's slice of the
+durable event log, resolvable provider transcripts, the run's slice of the
+usage sink, formula provenance, and rig git evidence.
+
+## Read-only and best-effort
+
+Every source is read only; nothing about the profiled run is mutated. A source
+that is missing, unreadable, or unresolvable is recorded in the manifest's
+`gaps` list rather than failing the capture — the one exception is the rig bead
+store, without which there is no run to profile.
+
+Two collects of the same closed run produce byte-identical `beads.json`, so the
+per-file hashes in the manifest are comparable.

+# gc profiler compare
+
+Diff two profile reports: run totals, and per-step wait and active deltas for
+steps whose titles match across the two runs.
+
+## Usage
+
+```bash
+gc profiler compare <root-a> <root-b> [--city <path>]
+```
+
+Both captures need a `report.json`, so run `gc profiler report <root> --json`
+for each first. Steps present in only one of the runs are counted, not diffed.
+
+## Reading the output
+
+Deltas are B minus A. Per-step rows are printed only when a wait or active
+delta exceeds 0.05 m, so run-to-run jitter does not bury the real movement. A
+value that cannot be computed — an in-flight run has no total, an unclosed step
+has no active time — prints as `—` rather than as zero.
+
+The intended baseline is a `bench-nullop` run: its steps do no real work, so
+comparing two of them measures pure orchestration overhead with no LLM
+variance.

+# gc profiler report
+
+Render the timing and cost analysis for a capture written by
+`gc profiler collect`. Formula-agnostic and deterministic: every figure comes
+from the capture, nothing is estimated except the cost figure, which is labeled
+as an estimate.
+
+## Usage
+
+```bash
+gc profiler report <root-bead-id> [--capture <dir>] [--city <path>] \
+                   [--json] [--html] [--out <dir>]
+```
+
+Default output is text on stdout. `--json` writes `report.json` (schema
+`gc.profile.report.v1`, the input `gc profiler compare` reads) and `--html`
+writes a self-contained `report.html` with a step Gantt and session lanes. Both
+land in the capture dir unless `--out` says otherwise.
+
+## What it derives
+
+Step spans (ready → started → closed, where ready is the later of the bead's
+creation and its last blocker's close, so dispatch wait is not confused with
+blocked time), session lanes grouped by role, run totals, a per-run and
+per-step token/cost rollup, and findings tagged with the layer that can fix
+them (`formula` / `config` / `platform`).
+
+## In-flight runs
+
+A root with no `closed_at` reports as in flight: elapsed time instead of a
+total, started-but-unclosed steps shown as `running`, and a time axis anchored
+on the latest timestamp in the capture rather than on wall clock — so
+re-rendering the same capture later does not move the axis.
+
+## Reading the cost figure
+
+Cost is a list-price estimate for decision support, not a charge. Facts with no
+pricing are counted as unpriced and excluded from the estimate rather than
+counted as free, and facts that resolve to no captured step are reported as
+unattributed. Both counts print with the total; neither is silently folded in.

+//     which a claim (the final name) exists without its content (the
+//     linked inode already holds the fully-fsynced bytes).

+//     counter (ErrStale) rather than silently overwritten.
+//   - Files are 0600 inside a 0700 directory. Filenames derive from the
+//     origin through safeStorageID, which hashes long or hostile
+//     components so a crafted ts/channel can neither escape the directory
+//     nor produce an unbounded name.

+// A crash between the temp write and the link, or between a rename's

+Record the singleton per-agent DM binding (agent -> session).
+
+Each agent identity app owns exactly one DM-bound session: a human DM to
+the agent's app wakes this session with `kind: dm`. The binding is
+singleton by construction — rebinding the same agent replaces the session
+in place, so ambiguity is impossible. A woken DM with no binding is a
+recorded delivery failure (`failed_dm_unbound`), recoverable via
+`gc slack company-redrive` after a binding is imported — never a legacy
+fallback.
+
+The agent must already exist in the imported company directory
+(<cityPath>/.gc/slack/company_directory.json). A missing directory or an
+unknown agent name is rejected non-zero. The binding is written to
+<cityPath>/.gc/slack/dm_bindings.json (override with
+$SLACK_COMPANY_DM_BINDINGS_PATH) via an atomic temp-file + rename.
+
+`--city` city-qualifies the binding when the session lives in a different
+gc city on the same host (the adapter needs a matching
+$SLACK_COMPANY_CITY_APIS entry); empty means the adapter's own city. A
+(session, city) pair may DM-bind only one agent.

+# gc slack company-redact
+
+Operator redaction of a single company-room receipt's raw stored body. The
+adapter truncates the receipt's body sidecar
+(`bodies/<receipt_id>.body.json`) to a fixed tombstone
+(`{"redacted": true, "event_digest": ...}`) **atomically**, in place. The
+receipt itself — its status, targets, and the immutable `event_digest` —
+is untouched, so late-redelivery dedup semantics are unchanged.
+
+This is a **manual operator hook only**. It is not wired to any automatic
+trigger in this phase; the eventual automatic trigger is the ledger's
+`core_bound` fence (raw payload retained only until the qualified core
+receipt reference is durable, then redacted).
+
+Redaction is fenced to receipts that are safe to strip:
+
+- **Terminal only.** A non-terminal (`received`/`routing`) receipt is
+  refused (`409`). Delivery re-reads the body on every attempt, so
+  truncating a still-in-flight receipt would recompute routing from an
+  empty message (terminalizing it under a misleading reason) or re-render a
+  redrive with empty text under the same `Idempotency-Key`.
+- **Past the reconciliation horizon.** A receipt younger than the outbound
+  reconciliation window (the `INTENT_TTL_SECONDS` horizon, 24h) is refused
+  (`409`): a stuck `posting` intent may still reconcile against this
+  receipt's body nonce, and erasing it early would wedge that intent.
+
+After redaction, readers degrade gracefully: hydration reads the body as
+`context_unavailable` and reconciliation treats it as a no-match. A redrive
+of a redacted receipt still runs — its route, idempotency keys, and frozen
+`thread_root_ts` are on the receipt, not the body — but it **re-renders the
+reminder WITHOUT the original message text** (the body is gone). Redact only
+once the raw text is no longer needed for delivery.
+
+## Usage
+
+```bash
+gc slack company-redact (--receipt <id> | --origin <team>:<channel>:<ts>)
+```
+
+## Flags
+
+- `--receipt <id>` — the receipt whose body to redact. Mutually exclusive
+  with `--origin`.
+- `--origin <team>:<channel>:<ts>` — select the receipt by message origin.
+
+## Errors
+
+- `404` — the receipt is terminal and already swept past the 7-day
+  retention horizon (including a sweep that raced this call); there is
+  nothing left to redact.
+- `409` — one of: the receipt's single-flight is held elsewhere (a
+  concurrent delivery or redrive; the verb retries a few times); the
+  receipt is a legacy embedded receipt with no separable body; the receipt
+  is not terminal (redaction is fenced to `core_bound`-equivalent terminal
+  state); or the receipt is younger than the reconciliation horizon. Only
+  the held-single-flight case is retried — the others are surfaced with the
+  endpoint's machine-readable reason and stop.
+
+## Connection
+
+The adapter's internal listener is reached over `GC_SERVICE_SOCKET`
+(a Unix domain socket, gc proxy_process mode) when set, else TCP to
+`LISTEN_INTERNAL` (default `127.0.0.1:8766`). `GC_SERVICE_SOCKET` wins.

+# gc slack company-redrive
+
+Operator redrive of failed or parked company-room receipt deliveries,
+without reposting to Slack. The adapter resets the selected targets and
+re-triggers delivery **reusing the same recorded idempotency keys**, so a
+redrive is safe with respect to gc's session-message dedup.
+
+Two legs, chosen by the receipt on the adapter side:
+
+- Receipts **with frozen targets** — the selected targets (default: every
+  `failed` target; `--target` filters) are reset to `pending`
+  (`attempts: 0`, detail `operator_redrive`), the receipt returns to
+  `routing`, recovery backoff is cleared, and delivery re-triggers.
+- Receipts **with no recorded targets** (a `correlation_recovery_exhausted`
+  or parked receipt — this verb is the designated recovery path) — the
+  receipt resets to `received`, its reason and recovery fields clear, and
+  first-routing re-runs from correlation.
+
+## Usage
+
+```bash
+gc slack company-redrive (--receipt <id> | --origin <team>:<channel>:<ts>) \
+                         [--target <session>]... [--include-failed]
+```
+
+## Flags
+
+- `--receipt <id>` — the receipt to redrive. Mutually exclusive with
+  `--origin`.
+- `--origin <team>:<channel>:<ts>` — select the receipt by message origin.
+- `--target <session>` — restrict to this target session; repeatable.
+  Default is every `failed` target.
+- `--include-failed` — **required** to touch a target whose detail begins
+  `attempts_exhausted`.
+
+## `attempts_exhausted` caveat
+
+An `attempts_exhausted` target's earlier timeouts had **unknown**
+outcomes, and gc's idempotency cache is best-effort (in-memory, bounded
+TTL) — the message may already have been delivered. Check the target
+session transcript before `--include-failed`; the reused idempotency key
+suppresses a *cached* duplicate but is not a durable exactly-once
+guarantee until the Phase 5 ledger lands.
+
+## Errors
+
+- `404` — the receipt is terminal and already swept past the 7-day
+  retention horizon; there is nothing left to redrive.
+- `409` — the receipt's single-flight is held elsewhere (a concurrent
+  delivery or redrive); the verb retries a few times, then asks you to
+  re-run.

+# gc slack company-status
+
+One view of a company-room flow end to end. Joins **Python-owned reads**
+— delegation records grouped by their synthesis group (5-tuple:
+team, channel, thread root, requester bot user, requester session), each
+with its S10-normalized synthesis snapshot, plus stale `posting`
+delegation intents (age past their retry deadline) — with the adapter's
+**receipt state** read over the internal listener
+(`GET /internal/company/receipts`): parked receipts, per-target delivery
+state, recovery/backoff fields, and ack state.
+
+This verb is read-only. The receipt store has a single writer (the
+adapter); `company-status` never mutates it.
+
+## Usage
+
+```bash
+gc slack company-status [--receipt <id>] \
+                        [--origin <team>:<channel>:<ts>] \
+                        [--root <team>:<channel>:<root_ts>] \
+                        [--status <status>]
+```
+
+## Flags
+
+- `--receipt <id>` — restrict the receipt listing to one receipt id.
+- `--origin <team>:<channel>:<ts>` — scope to one message origin.
+- `--root <team>:<channel>:<root_ts>` — scope to one human root thread
+  (groups, stale intents, and receipts sharing that root).
+- `--status <status>` — filter receipts by status.
+
+## Output
+
+A JSON document with `groups` (each carrying its delegations and their
+normalized `synthesis` snapshots), `ungrouped_delegations`,
+`stale_posting_intents`, and `receipts`. A not-ready synthesis snapshot
+alongside a `correlation_pending` / `ambiguous_pending_delegations`
+receipt park is exactly the wedged-flow shape this verb surfaces.
+
+## Connection
+
+The adapter's internal listener is reached over `GC_SERVICE_SOCKET`
+(a Unix domain socket, gc proxy_process mode) when set, else TCP to

+Delegate the current company-room turn to a peer agent.
+
+Posts `<@peer> <your body>` into the human root's thread as *your own*
+identity app, carrying a content-addressed nonce in Slack message metadata
+so the peer's result can be correlated back to a durable delegation record.
+The body is entity-escaped (`&`, `<`, `>`); the service-constructed
+`<@peer>` is the only live mention — bare `@channel` / `@here` / `#channel`
+text stays inert.
+
+Context is resolved from the immutable turn record named by `--turn-ref` in
+the authenticated Slack reminder: the room, team/channel, human root thread,
+and your acting agent all come from that exact delivery even if another room
+wakes the same session while you work. `$GC_SESSION_NAME` must be set (hard
+error otherwise). Legacy pre-rollout pointers remain readable; post-rollout
+turns fail closed when `--turn-ref` is omitted.
+
+Durability and safety:
+
+- A posting intent is persisted before the provider POST
+  (`prepared → posting → published | failed | expired`, bounded attempts,
+  120s retry deadline, 24h TTL). A crash mid-post is recovered lazily on the
+  next company verb by scanning ingress receipts for the nonce — never by
+  reposting (`chat.postMessage` is not idempotent).
+- At most one pending delegation is allowed per
+  `(team, channel, thread_root, responder, requester)`, enforced under a
+  cross-process lock. A TTL-expired pending delegation counts as
+  not-pending.
+- On success the delegation record is materialized before the command
+  reports `posted_ts`. A definitive provider rejection fails the intent; a
+  timeout/5xx parks it for automatic recovery (reported as `parked`).
+
+Flags
+-----
+
+  --to <agent>         Target agent name (directory slug). Required.
+  --body <text>        Delegation body (or use --body-file).
+  --body-file <path>   Read the body from a file.
+  --cancel             Expire your own pending delegation to --to (recover a
+                       wedged tuple without waiting out the TTL).
+  --origin-ts <ts>     Pin a specific turn when a newer wake overwrote the
+                       pointer.
+  --turn-ref <ref>     Immutable turn reference from the Slack reminder.

+  - ambient_wake (members woken by plain human messages)
+  - mention_wake (members eligible for native @-mention activation)
+  - bindings (the (agent -> session) delivery targets for the room)

+Switchboard/member presence is checked best-effort against

+Register a per-agent Slack app signing secret for app-bound DM verification.
+
+Each agent identity app that subscribes to `message.im` (Phase 4 DMs) must
+have its signing secret registered so the adapter can verify DM event POSTs
+against THAT app's secret — the multi-secret trial alone proves only that
+*some* registered app signed the request, which must never let one app's
+secret admit events into another agent's DM spool.
+
+The record `{team_id, api_app_id, signing_secret}` is written to
+<cityPath>/.gc/slack/agent_apps.json (override with
+$SLACK_COMPANY_AGENT_APPS_PATH), mode 0600. This registry is secret-bearing:
+if it already exists with group/world-accessible permissions the verb refuses
+to overwrite it (a possible leak — fix perms and rotate before re-running).
+Re-registering an api_app_id replaces its secret (rotation).
+
+Owner-agent identity is not stored here; it derives by joining api_app_id
+against company_directory.json agents[].app_id. Registering an api_app_id with
+no directory agent succeeds with a warning (it admits nothing until the
+directory lists it), so a secret can be registered before the directory import
+(runbook ordering).
+
+Validation: api_app_id `^A[A-Z0-9]{6,}$`, team_id `^[TE][A-Z0-9]{6,}$`,
+signing secret a 32-character hex string.
+
+Examples

+# Slack Company Rooms — Implementation Plan
+
+Companion to `slack-full/docs/company-rooms.md` (v2). Reference
+implementation: the Discord company-rooms branch
+(`feat/discord-company-rooms`), whose behavioral contract this pack
+reproduces on Slack.
+
+Verification bar for every phase (matches CI; each line runs from the repo
+root):
+
+```sh
+(cd slack-full/adapter && gofmt -l . && go vet ./... && go test -race ./...)
+(cd slack-full/cli && go test -race ./...)
+python3 -m pytest slack-full/tests -q
+```
+
+## Phase overview
+
+| Phase | Scope | Acceptance rules |
+| --- | --- | --- |
+| 1 | Durable admission, company directory + bindings, deterministic human routing | 1, 2, 4 (non-delegation legs), 6, 8, 9, 10, 11 |
+| 2a | Agent identity app provisioning (manifest template, install, harvest, secrets) | pilot checklist |
+| 2 | Per-agent tokens, delegation, results, trust envelope, hydration | 3, 5, 7, remaining legs of 4 |
+| 3 | Synthesis snapshots, ordered replay, correlation backoff, receipt redrive, visible acks | Phase 3 acceptance proofs 1–8 |
+| 4 | Per-agent DMs | 12 |
+| 5 | Durable-request-ledger `/v0` integration | blocked on gascity drafts landing |
+
+Company-room behavior stays additive throughout: nothing changes until
+`gc slack import-company-directory` has produced a valid directory registry,
+and non-company rooms keep legacy behavior in every phase.
+
+---
+
+## Phase 1 — durable admission + directory + human routing
+
+Sub-phases 1a–1c are independent new files (parallelizable). 1d wires them
+into the adapter (sequential, after 1a–1c). 1e is the Python/CLI surface
+(parallel with 1d).
+
+Delivery guarantee in this phase (stated honestly): at-least-once with
+receipt-side suppression. Each session submission carries
+`Idempotency-Key: ingress:<id>:target:<session>` as an HTTP header, but
+gc's idempotency cache is in-memory with a bounded TTL, so the durable
+receipt is the authority; a crash between gc submission and the receipt's
+delivery record may duplicate that one target. Phase 5 upgrades this.
+
+### Normalized registries (shared contract for 1a and 1e)
+
+Two CLI-written JSON files, resolved exactly like the existing registries
+(same directory as `apps.json`), each with an env-var path override
+following the existing per-registry override convention (add
+`SLACK_COMPANY_DIRECTORY_PATH`, `SLACK_COMPANY_BINDINGS_PATH`, and
+`SLACK_COMPANY_INGRESS_DIR`, mirroring the style of the existing overrides
+around `main.go:497-507`; the Python CLI resolves the identical paths).
+Both are staged/committed **outside** the six-registry atomic reload with
+their own last-known-good retention, so an invalid company file never
+blocks the other registries' SIGHUP.
+
+`company_directory.json` — written by `import-company-directory`; wildcards
+expanded at import time; the Go loader re-validates and fails closed:
+
+```json
+{
+  "schema_version": 1,
+  "source_sha256": "<hex of the imported TOML>",
+  "imported_at": "<RFC3339>",
+  "agents": [
+    {"name": "ollie", "app_id": "A0AAAAAA1", "bot_user_id": "U0AAAAAA1"}
+  ],
+  "rooms": [
+    {
+      "name": "orchestrator-team",
+      "team_id": "T0AAAAAAA",
+      "channel_id": "C0AAAAAAA",
+      "members": ["ollie", "riley"],
+      "ambient_wake": ["ollie"],
+      "mention_wake": ["ollie", "riley"]
+    }
+  ]
+}
+```
+
+`company_bindings.json` — written by `bind-company-agent`; singleton by
+construction:
+
+```json
+{
+  "schema_version": 1,
+  "bindings": [
+    {"room": "orchestrator-team", "agent": "ollie", "session": "ollie-main"},
+    {"room": "orchestrator-team", "agent": "riley", "session": "teams__it",
+     "city": "platform"}
+  ]
+}
+```
+
+`city` is optional (city-qualified binding): the live org runs one team
+per gc city, each with its own supervisor API, while the switchboard
+stays the single admission owner. A city-qualified target is delivered
+to that city's API base, resolved from the adapter env
+`SLACK_COMPANY_CITY_APIS`
+(`"platform=http://127.0.0.1:8377,orchestration=http://127.0.0.1:8374"`);
+an unmapped city is a definitive per-target configuration failure
+(operator fixes the map and redrives). City values are URL-interpolated
+and validated fail-closed against URL-significant/whitespace bytes on
+both sides. The frozen `TargetDelivery` and the current-turn pointer
+carry the city so redrives and verbs stay city-stable. Cross-city
+sessions additionally need the slack pack imported into their city and
+the `SLACK_COMPANY_*` state paths pointed at the adapter's dirs (shared
+filesystem) for the reply verbs to function.
+
+Validation (both sides, fail closed): lowercase slug names; unique names,
+`app_id`s, `bot_user_id`s, room names, `(team_id, channel_id)` pairs;
+`ambient_wake ⊆ members`, `mention_wake ⊆ members`; wildcard permitted in
+TOML `members`/`mention_wake` only (never `ambient_wake`), absent from the
+normalized JSON; unknown agent references invalid; at most one binding per
+(room, agent); binding room/agent must exist in the directory at load time
+(a binding referencing a missing room/agent is dropped with a warning, not
+fatal); empty `agents`/`rooms`/`bindings` valid.

+Snapshot holders (`companyDirectoryStore`, `companyBindingsStore`) with
+`Load(path)` / `Snapshot()` / `StageReload(path)` semantics. **Deliberate
+divergence from the other registries**: `Load` at startup is never fatal —
+a corrupt or invalid file logs the validation error and installs a nil
+snapshot (company routing disabled) while the adapter keeps serving legacy
+traffic. Reload failure keeps last-known-good. Nil snapshot = no company
+routing.
+
+Tests: every validation rule (table-driven); duplicate/unknown references
+fail; corrupt file at construction → nil snapshot + surfaced error,
+process viable; last-known-good retention on bad reload; binding referencing
+removed room/agent dropped with warning; empty registries inert.

+produce no wakes.
+
+### 1d — adapter wiring (`main.go`, `company_ingress_test.go`)
+
+- Load both company registries at startup (never fatal — nil snapshot on
+  error) and stage/commit them on SIGHUP **outside** the six-registry
+  atomic set, with their own last-known-good log lines.
+- `handleSlackEvents` changes, inserted between the `url_verification`
+  return (~main.go:1917-1921) and the current unconditional
+  `w.WriteHeader(StatusOK)` (~main.go:1924):
+  - Synchronously decode the inner event when the envelope is an
+    `event_callback` (the current code defers this to the async goroutine;
+    the company path needs channel/ts/subtype before acking). Extend the
+    event struct with `Blocks json.RawMessage`.
+  - If `(team_id, channel)` matches a directory room: apply the
+    admissibility gate (allowlist; non-admissible → 200, no receipt;
+    unkeyable → log + 200); capture `X-Slack-Retry-Num`/`-Reason` from
+    `r.Header`; `Admit`; duplicate → 200; created → trigger delivery and
+    200; store failure → 503 **without** `x-slack-no-retry`.
+  - Non-company events keep today's path byte-for-byte.
+  - Admission never depends on `acquireDispatchSlot`: the semaphore gates
+    only the async delivery trigger; if no slot is free the receipt simply
+    stays pending for the sweep (backpressure, not drop).
+- Company delivery worker: in-process single-flight per receipt ID;
+  claims the receipt (`Status: routing` via generation-checked Update);
+  computes the wake set (1c) only when the receipt has no recorded
+  targets — recorded targets are a frozen route that redrives drive to
+  terminal states, never recompute (`no_delivery` is legal only with no
+  recorded targets and an empty freshly-computed wake set); resolves each
+  wake through the company-bindings snapshot (missing binding → target
+  `failed` with reason, no legacy fallback); delivers each target via a
+  new `deliverToCompanySession` helper — POST
+  `/v0/city/{city}/session/{session}/messages` with header
+  `Idempotency-Key: ingress:<id>:target:<session>`, an explicit
+  per-request timeout, and the system-reminder-style envelope used by
+  alias dispatch (markup-neutralized); marks a target `delivered` only on
+  gc's acknowledged 2xx; leaves it `pending` (attempts++) on
+  timeout/5xx/408/429/connection error for sweep retry with the same
+  key; marks it `failed` on any other 4xx or when the bounded attempts
+  cap is exhausted; sets the terminal receipt status when all targets
+  resolve. `app_mention` events for company-room channels are owned by
+  the company path (200, no receipt, no legacy dispatch).
+- Parking: a pending receipt whose channel matches no *current* directory
+  room (including nil directory) is left pending with
+  `Reason: parked_no_directory_room` — never terminally resolved, never
+  legacy-delivered; the sweep retries it after every directory change.
+- Startup recovery barrier, company-scoped: legacy routes, `/healthz`,
+  interactions, and the internal listener serve immediately; company-room
+  admissible events get 503 (retryable) until one synchronous
+  `Pending()` scan completes and its receipts are enqueued. (Posting
+  intents precede pending ingress in the barrier ordering from Phase 2
+  on.) `/healthz` detail is the sole adapter status surface: barrier
+  state, receipt-store health and `WriteFailures()`, delivery-failure
+  count, and directory/bindings snapshot state. Membership warnings
+  surface only via the Python `import-company-directory`/`peers` path in
+  Phase 1. A receipt-store construction failure at startup puts the
+  gateway in degraded mode — company-admissible events 503 (never
+  legacy), `/healthz` reports the store error, and construction is
+  retried — it is never a silent fallthrough to legacy.
+- Periodic sweep (60s) starts after one successful barrier pass, waits one
+  interval first, respects the routing-claim stale-reclaim window (skip
+  receipts whose `UpdatedAt` is fresher than 5 minutes unless terminal).
+- Company rooms bypass legacy generic fanout and alias dispatch
+  deterministically.
+
+Integration tests (`company_ingress_test.go`, httptest): acceptance 8
+(admit, crash before delivery → restart delivers exactly once; crash
+after submit before record → second delivery attempt carries the same
+Idempotency-Key), 9 (retry-num redelivery → 200, no second delivery), 10
+(store failure → 503 without no-retry header + counter increment;
+subsequent retry admits), 11 (parked receipt: directory removed → stays
+pending; restored → delivers), ambient and mention routing end-to-end,
+saturation backpressure (no slot → receipt pending, sweep delivers),
+legacy path untouched for non-company channels.
+
+### 1e — CLI surface (Python)
+
+New script `slack-full/scripts/slack_company_directory.py`: TOML parse
+(`tomllib`), full validation, wildcard expansion, normalized JSON emission
+(atomic tmp+rename) for both registries, `source_sha256`, membership
+verification via `conversations.info`/`conversations.members` (warnings,
+not failures, when the token lacks scopes or the bot is not a member),
+`peers` listing (rooms, members, wake policy, bindings, membership
+warnings). Command wrappers follow the shipped convention —
+`commands/<verb>.sh` at the top level plus `commands/<verb>/command.toml`
+(with `run = "../<verb>.sh"`) and `commands/<verb>/help.md` — for three
+verbs: `import-company-directory`, `bind-company-agent`, `peers`. No
+`pack.toml` registration exists or is needed (verb discovery is
+directory-driven). Tests (`tests/test_slack_company_directory.py`):
+validation table mirrored from 1a, TOML→JSON golden file, idempotent
+re-import, invalid file leaves the existing registry untouched, bind
+create/replace, peers output including membership warnings (Slack API
+mocked).
+
+---
+
+## Phase 2a — agent identity app provisioning
+
+Manifest template for agent identity apps (`manifest/agent-app.json` +
+README section): bot user, `chat:write`, `app_home.messages_tab_enabled:
+true`, `messages_tab_read_only_enabled: false`, interactivity off, **no
+event subscriptions** (the DM phase adds `message.im` + `im:history`).
+Switchboard manifest (`manifest/app.json`) gains `channels:read`,
+`groups:read` (membership checks) and `users:read` (`bots.info` author
+resolution) — scope changes require reinstall, called out in the runbook.
+Operator steps documented: create/install per agent, harvest `app_id` +
+`bot_user_id` into the directory TOML, register each signing secret with
+the adapter (existing `import-app` flow), drop each bot token into the
+company secrets dir (the token loader refuses files not 0600, dirs not
+0700, and symlinks — validation, not trust), invite each member bot to
+its rooms. These apps are internal, never Marketplace-distributed
+(distribution would demote `conversations.*` rate tiers).
+
+## Phase 2 — identities, delegation, results, hydration
+
+Ownership split (mirrors the Discord reference): **Python owns company
+outbound** — intents, per-agent token files, `chat.postMessage`,
+delegation-record creation, lazy recovery, pruning — exactly as
+`discord_chat_delegate.py` / `discord_intake_common.py` do; **Go owns
+ingress** — author resolution, trust checklist, result-claim and expiry
+transitions on delegation records, peer envelopes, hydration, the
+per-session current-turn pointer. Both sides write shared on-disk state
+under the adapter state root; every schema below is the cross-language
+contract, validated fail-closed on both sides, serialized by the lock
+contract below.
+
+### Shared state contract (pins 2b and 2c)
+
+Paths (env override > `<GC_CITY_PATH>/.gc/slack/<leaf>` >
+`/tmp/gc-slack-adapter/<leaf>`, matching Phase 1 conventions):
+- `SLACK_COMPANY_SECRETS_DIR` > `secrets/` — token files
+  `bot-token-<agent>.txt`, 0600 in 0700 dir, one per directory agent.
+- `SLACK_COMPANY_INTENTS_DIR` > `company-delegation-intents/` —
+  `<nonce>.json`, written by Python only.
+- `SLACK_COMPANY_DELEGATIONS_DIR` > `company-delegations/` — created
+  once by Python at publish (O_EXCL/link create-once; `EEXIST` = adopt
+  the existing record, never overwrite); status transitions
+  (claim/expiry) written by Go, expiry also by Python's lazy pruner.
+- `SLACK_COMPANY_TURNS_DIR` > `company-current-turn/` —
+  `<session>.json`, written by Go only (the delivery worker), read by
+  the Python verbs.
+- `SLACK_COMPANY_LOCKS_DIR` > `locks/` — advisory lock files (below).
+
+**Lock contract.** All cross-process critical sections use an advisory
+`flock(LOCK_EX)` (`fcntl.flock` in Python, `syscall.Flock` in Go) on
+`locks/<label>-<sha256hex(NUL-joined key fields)[:16]>.lock`. Two locks
+exist in Phase 2: the **delegation-tuple lock** (label `dtuple`, key =
+team, channel, thread_root_ts, responder_bot_user_id,
+requester_bot_user_id), held by `delegate` across its
+scan → intent-create → post → record-materialize section, by `--cancel`,
+by Go's claim transition, and by any expiry rewrite; and the
+**intent lock** (label `intent`, key = nonce) for attempts-CAS updates.
+Generation checks remain on top of the locks (defense in depth), but
+the locks are what make cross-process read-modify-write sound.
+
+**Filename sanitizer (byte-for-byte cross-language spec).** For each
+component: bytes outside `[A-Za-z0-9._-]`, a leading `.`, the string
+`..`, or length > 64 cause the component to be replaced by
+`h<sha256hex(component)[:16]>`; otherwise the component passes through.
+Delegation filename: `dg-<san(team)>-<san(channel)>-<san(ts)>-`
+`<sha256hex(team NUL channel NUL ts)[:12]>.json` (digest suffix always
+present, mirroring Go `receiptID`). 2d ships golden filename fixtures
+both suites must reproduce exactly.
+
+**Root derivation (normative).** From the triggering receipt's stored
+event: `human_root_ts := Event.thread_ts if non-empty else Event.ts`.
+`thread_ts` on `chat.postMessage` must always be a parent — Slack
+documents replying to a reply as invalid. 2c's root verifier grants
+`root_provenance: human_root_verified` only when the fetched root is a
+parent (`thread_ts` absent or equal to `ts`) AND its author is a non-bot
+human; otherwise `root_unverified`.
+
+`company-delegation-intents/<nonce>.json` — created BEFORE any provider
+POST, for delegations AND for results/synthesis (an `op` field:
+`delegation | result | synthesis`; every company post goes through the
+intent path so no post can double on a timeout). Nonce = `gcs-` + first
+20 hex of sha256 over the canonical anticipated record: (source app_id,
+source bot_user_id, target agent, target bot_user_id, team, channel,
+human_root_ts, body_sha256, retry_seq) — `retry_seq` is monotonic:
+`max(retry_seq of existing intents for the tuple) + 1` when minting
+fresh (never a file count, so pruning cannot re-mint a used nonce), and
+the pruner always retains the highest-seq intent per tuple. Crash
+retries of one logical delegation resume the existing intent; successive
+logical delegations mint fresh nonces:
+
+```json
+{
+  "schema_version": 1,
+  "nonce": "gcs-<20hex>",
+  "retry_seq": 0,
+  "status": "prepared",
+  "attempts": 0, "max_attempts": 3,
+  "created_at": "<RFC3339>", "updated_at": "<RFC3339>",
+  "retry_deadline": "<RFC3339: first attempt + 120s>",
+  "ttl_seconds": 86400,
+  "source_agent": "ollie", "source_app_id": "A…", "source_bot_user_id": "U…",
+  "target_agent": "riley", "target_bot_user_id": "U…",
+  "team_id": "T…", "channel_id": "C…", "room": "orchestrator-team",
+  "human_root_ts": "1700000000.000100",
+  "requester_session": "ollie-main",
+  "body_sha256": "<hex>",
+  "posted_ts": ""
+}
+```
+
+Statuses: `prepared → posting → published | failed | expired`.
+Attempts updates under the intent lock. **Recovery is lazy and
+Python-owned** (accepted deviation from the Phase 1 barrier-ordering
+sentence, which is amended): every company verb invocation first runs a
+bounded reconciliation pass over `posting` intents. Reconciliation does
+NOT call the Slack API: the delegation post, arriving back through the
+switchboard, is itself admitted as a bot-message receipt whose stored
+raw event embeds the posted metadata — reconciliation scans the
+receipts dir (read-only) for a bot-authored receipt in (team, channel)
+whose `metadata.event_payload.nonce` equals the intent nonce; found →
+adopt its origin `ts` as `posted_ts`, mark `published`, materialize the
+delegation record if absent; not found and past `retry_deadline` → the
+intent stays parked (`posting`) — never repost on ambiguity
+(`chat.postMessage` is not idempotent). The Go sweep surfaces a count of
+stale `posting` intents (age > retry_deadline) on `/healthz` as the
+operator signal. Existing-nonce handling at `delegate` time: `prepared`
+→ adopt and resume (nothing was ever posted; safe to proceed to
+posting); `posting` → resume reconciliation; `published` with its
+delegation record still `pending` → the one-pending error below;
+anything terminal → mint a fresh nonce at the next `retry_seq`.
+
+`company-delegations/<key>.json` (key per the sanitizer spec) —
+materialized before the CLI reports success:
+
+```json
+{
+  "schema_version": 1,
+  "generation": 1,
+  "nonce": "gcs-<20hex>",
+  "room": "orchestrator-team",
+  "team_id": "T…", "channel_id": "C…", "ts": "<posted_ts>",
+  "thread_root_ts": "<human_root_ts>",
+  "requester_agent": "ollie", "requester_bot_user_id": "U…",
+  "requester_session": "ollie-main",
+  "expected_responder_agent": "riley",
+  "expected_responder_bot_user_id": "U…",
+  "created_at": "<RFC3339>", "ttl_seconds": 86400,
+  "status": "pending",
+  "result_ts": "", "result_claimed_at": ""
+}
+```
+
+**Result correlation (normative; Slack deviation from Discord).** Slack
+has no nested replies — delegation and result share the human root's
+thread. A claim requires ALL of: (1) the message passes the five-part
+peer trust checklist; (2) it is in thread `thread_root_ts`, authored by
+`expected_responder_bot_user_id`; (3) its native mention set includes
+`requester_bot_user_id`; (4) its `metadata.event_type ==
+"gc_delegation_result"` with `event_payload.nonce == record.nonce` and
+`event_payload.delegation_ts == record.ts` (the breadcrumb is
+load-bearing for claim ADMISSION — responder chatter, clarifying
+questions, and hand-typed posts deliver as ordinary peer input without
+consuming the claim; authorship remains the Slack-authoritative trust
+anchor, so metadata alone can never claim); (5) route window
+`-300s <= now - created_at <= ttl`. `delegate` enforces **at most one
+pending delegation per (team, channel, thread_root_ts, responder,
+requester)** under the tuple lock; TTL-expired `pending` records count
+as not-pending (and are rewritten `expired` under the lock). Go's claim
+(`pending → result_claimed`, under the tuple lock, generation-checked)
+is replay-idempotent; >1 pending record matching one claim key parks
+the receipt fail-closed (`ambiguous_pending_delegations`). A wedged
+flow is recoverable without the TTL: `gc slack delegate --cancel --to
+<agent>` transitions the caller's own pending record to `expired` under
+the lock.
+
+**Pruning (lazy, Python-owned).** Every company verb invocation prunes:
+terminal intents and terminal/expired delegation records older than 7
+days. The prune retention must be `>=` the maximum record
+`ttl_seconds` plus a one-hour clock-skew margin (the pruner clamps to
+that floor), so a record can never be S2-compatible on Go's clock
+while already prunable on Python's; snapshot scans tolerate concurrent
+deletion by skipping vanished files. The pruner always retains the
+highest-`retry_seq` intent per tuple (the monotonicity watermark);
+pruned files cannot collide because intent creation is O_EXCL on a
+fresh nonce.
+
+`company-current-turn/<session>.json` — written atomically by the Go
+delivery worker on EVERY company wake, before the gc session POST; the
+deterministic context source for the Python verbs (no receipt scanning):
+
+```json
+{
+  "schema_version": 1,
+  "session": "ollie-main",
+  "receipt_id": "in-…",
+  "team_id": "T…", "channel_id": "C…", "ts": "<origin ts>",
+  "room": "orchestrator-team",
+  "kind": "ambient | targeted | peer_input | peer_delegation | peer_result",
+  "thread_root_ts": "<derived root>",
+  "agent": "ollie",
+  "delegation_key": "<delegations filename; present iff kind is peer_delegation or peer_result>",
+  "delivered_at": "<RFC3339>"
+}
+```
+
+The delivered reminder text also displays the origin `ts`, and the verbs
+accept `--origin-ts` to pin a specific turn when a newer wake has
+overwritten the pointer (mismatch without the flag is a hard error
+telling the agent to pass it).
+
+Message metadata: delegations post `metadata: {event_type:
+"gc_delegation", event_payload: {v: 1, nonce, root_ts, requester,
+target}}`; results post `metadata: {event_type: "gc_delegation_result",
+event_payload: {v: 1, nonce, delegation_ts}}`. Metadata is embedded in
+the switchboard's `message.*` events (no extra scope) and is
+workspace-visible and mutable — breadcrumbs plus claim-admission gate;
+the durable record stays authoritative. Pilot wire capture must confirm
+metadata presence on a real agent-app post event.
+
+Composition contract (both verbs): top-level `text` only — no `blocks`,
+no `link_names`, `reply_broadcast` never set, default `parse` (bare URLs
+may auto-link; harmless, no notification) — body entity-escaped (`&`,
+`<`, `>`); the service-constructed mention is the only live entity.
+Delegation text: `<@target_bot_user_id> <escaped body>` with
+`thread_ts=human_root_ts`. Result text: `<@requester_bot_user_id>
+<escaped body>` with `thread_ts=thread_root_ts`. Synthesis: escaped
+body, no live mentions, `thread_ts=thread_root_ts`. All company posts
+are therefore visible in the human root's thread (not the channel
+timeline). Retry policy on `chat.postMessage`: explicit timeout; 429
+honors `Retry-After` within `max_attempts`; definitive 4xx → intent
+`failed`; timeout/5xx → reconcile-before-repost.
+
+Identity plumbing: the session namespace is the bound session NAME,
+obtained from `GC_SESSION_NAME` (hard error if unset); the anti-spoof
+check compares it to the pointer file's `session` and the (room, agent)
+binding. `bind-company-agent` rejects binding a session already bound
+to a DIFFERENT agent in the same room, so `delegate`'s reverse
+resolution session → (room, agent) is unambiguous.
+
+### 2b — Python outbound (`scripts/slack_company_outbound.py` + verbs)
+
+New module `slack_company_outbound.py` (intents store with lock/CAS,
+token loader with permission/symlink refusal, sanitizer, escaping/
+composition, postMessage with metadata, bounded retries, receipt-based
+reconciliation, lazy pruner) + `gc slack delegate` verb (3-file
+wrapper, including `--cancel`) + `reply-current` gaining
+company-context awareness: it reads `company-current-turn/<session>`;
+`kind: peer_delegation` → post the result (acting agent's own token,
+metadata gate attached) and report `posted_ts` only on success; `kind:
+peer_result` → post the synthesis to the human root with no live
+mentions; ambient/targeted → unchanged legacy behavior for non-company
+context, company rooms answer into the root thread. Tests: hermetic
+(mocked Slack API), covering intent lifecycle incl. receipt-based
+reconciliation (nonce receipt found → adopt + materialize; absent →
+parked, never reposted), retry_seq nonce freshness after terminal
+intents, one-pending-per-tuple under two concurrent delegates (real
+flock race test), `--cancel`, composition/escaping (`@channel @here
+#general <!channel>` inert; only the target mention live), root
+derivation from threaded and unthreaded triggers, token
+selection/permission refusal, Retry-After honored, definitive 4xx →
+failed, record create-once (EEXIST adopts), pointer-file consumption +
+`--origin-ts` mismatch error, pruning.
+
+### 2c — Go ingress (author resolution, trust, correlation, envelopes)
+
+- `company_authors.go`: cached `bot_id → bots.info → user_id` resolver
+  (switchboard token, `users:read`), TTL cache + singleflight.
+  Outcomes are split: definitive `bot_not_found`/`deleted` → unknown
+  bot (terminal for that message); transient (ratelimited — honor
+  `Retry-After` — timeout, 5xx, network) → park the receipt
+  non-terminally (`author_resolution_pending`) for sweep retry, never
+  a terminal `no_delivery`. Corroboration: the event's own
+  `app_id`/`bot_profile` fields pre-check, `bots.info`'s `app_id` must
+  match the directory agent's `app_id`, `event.user` must match when
+  present; any mismatch → unknown bot.
+- `company_routing.go`: `CompanyMessage` gains `ResolvedBotUserID
+  string` (populated by the delivery worker; keeps ComputeWakeSet
+  pure) and `Metadata json.RawMessage`; `slackMessageEvent` gains
+  `Metadata json.RawMessage`. The bot-authored mention-wake leg turns
+  on: AuthorCompanyBot (resolved, room member) with a native mention of
+  an eligible member routes per the table. Reason-code taxonomy
+  replacing `company_bot_phase2`: `company_bot_no_mention`,
+  `company_bot_not_member`, `unknown_bot`, `company_self` (existing),
+  plus routing-stage `mentioned_not_eligible` reasons — Phase 1 tests
+  pinning `company_bot_phase2` are updated in the same change.
+- `company_peer.go`: five-condition trust checklist with
+  machine-readable failure reasons; result-claim per the shared
+  contract (tuple lock + generation, metadata gate, requester-mention
+  check, replay-idempotent, `ambiguous_pending_delegations` parking);
+  plausible in-flight tuple (a `posting` intent exists) → park
+  `correlation_pending`; unmatched identifiable replies to the
+  switchboard rejected; everything else = ordinary peer delegation
+  processing.
+- `company_delivery.go`: writes `company-current-turn/<session>.json`
+  before each gc POST; envelope stays a single reminder string (gc API
+  unchanged) rendered from a pinned template with sections for kind,
+  `peer_authority: peer_only`, `root_provenance`, verified human root,
+  and the bounded excerpt — every interpolated value (root JSON fields,
+  each excerpt line) passes `neutralizeMarkupBoundaries`.
+  `TargetDelivery.Kind` grows `peer_delegation`/`peer_result` (Phase 1
+  fixtures updated). **Hydration is frozen**: the verified root and the
+  excerpt (`conversations.history`/`replies`: max 8 messages, 12KiB
+  total, 1024 chars each; failure → `context_status:
+  context_unavailable`, never broader routing) are fetched once at
+  first delivery and stored in a new receipt field `Hydration
+  json.RawMessage`, so redrives re-render identical bytes under the
+  same Idempotency-Key. Sweep gains the stale-`posting`-intent count
+  for `/healthz` (read-only scan).
+- Tests: acceptance 3 (trusted Ollie `@Riley` wakes Riley exactly once
+  through the full checklist), 5 (Riley's metadata-gated threaded
+  result wakes only Ollie and claims the record; a clarifying question
+  without result metadata delivers as peer input and claims nothing;
+  replay claims nothing twice), 7 (dormant mentioned agent gets
+  current message + verified root + bounded excerpt, no duplicate;
+  threaded human trigger derives the parent root), remaining rule-4
+  legs (unknown bot, non-member author, self, unresolvable
+  `bot_message`, mention of non-member, expired/claimed/ambiguous
+  results fall to peer input or park), transient `bots.info` failure
+  parks then delivers exactly once, hydration-failure marker, excerpt
+  bounds, frozen-hydration byte-identity across redrives,
+  pointer-file write ordering.
+
+### 2d — cross-language wire tests
+
+`slack-full/tests/fixtures/company/` golden files: intent record,
+delegation record, current-turn pointer, and sanitizer filename
+fixtures (hostile/long/dotted components). The Go and Python suites
+each parse, validate, and re-derive the same bytes. Interop is
+fixture-mediated across the two independent suites:
+`fixtures/company/interop/` holds records generated through the REAL
+Python code paths (with pinned clocks); the Python suite proves
+byte-stable regeneration, and the Go suite claims/consumes those exact
+bytes through its real claim and pointer paths. Lock-filename parity is
+pinned by identical derivations in both suites (verified:
+`dtuple-3a4b34ac4caada68.lock` from both languages for the same key).
+
+Pilot step: capture one real agent-app post event and assert the
+mention extractor, author classifier, AND embedded metadata match the
+wire shape the contract assumes.
+
+## Phase 3 — synthesis snapshots, ordered replay, redrive, visible acks
+
+Reference citations in this section: `CM` =
+`discord/scripts/discord_intake_common.py`, `GW` =
+`discord/scripts/discord_gateway_service.py`, `DOC` =
+`discord/docs/company-rooms.md`, all on `feat/discord-company-rooms`.
+
+Ownership split continues the Phase 2 pattern: **Go owns every synthesis
+write** — the claim-time snapshot freeze (it already owns the claim
+transition), group/serialization locks on the ingress side, replay
+ordering, correlation backoff, reactions, and the receipt-redrive
+surface; **Python owns the agent-facing reads** — the snapshot validator
+behind `reply-current`'s synthesis gate, the one-hop gate in `delegate`,
+and the new operator verbs (thin clients of the adapter's internal
+listener; the receipt store keeps exactly one writer). Every schema and
+lock below is cross-language contract, validated fail-closed on both
+sides.
+
+### Shared state contract additions (pins 3a–3c)
+
+**Synthesis group (normative).** The canonical durable root shared by
+sibling delegations is the 5-tuple, in this pinned field order:
+
+```
+(team_id, channel_id, thread_root_ts, requester_bot_user_id, requester_session)
+```
+
+A delegation record belongs to a group iff all five fields are non-empty
+(Phase 2 record validation already guarantees this for parseable
+records; an unparseable record has no group and is never claimable).
+**Deviation D1 (normative):** Discord's group is an 8-tuple including
+`root_ingress_receipt_id`, `source_app`, and the gc session *ID*
+alongside the name (CM:2250-2291). On Slack the human-root receipt ID
+is a pure function of `(team_id, channel_id, thread_root_ts)` and the
+requester's app is 1:1 with `requester_bot_user_id` under directory
+uniqueness — those dimensions are derivable. The session-incarnation
+dimension is NOT derivable: Phase 2 records carry only the session
+name (`GC_SESSION_NAME`), so a requester session destroyed and
+recreated under the same name mid-flight joins the dead incarnation's
+group, and the stale incarnation's pending delegations freeze new
+claims not-ready until their 24h TTL or `gc slack delegate --cancel`.
+This is an accepted, declared consequence (failure direction is safe:
+not-ready + operator-resolvable), revisited if gc ever exposes a
+stable session incarnation ID to the verbs. Two implementations
+disagreeing on the group tuple is a correctness bug; 3c pins it with a
+fixture.
+
+**Locks.** Two new labels under the existing Phase 2 lock contract
+(`locks/<label>-<sha256hex(NUL-joined key fields)[:16]>.lock`,
+`flock(LOCK_EX)`):
+
+- **Group lock** — label `dgroup`, key = the 5 group fields in pinned
+  order. Serializes result claims for one group (DOC:155-157;
+  CM:2510-2521). When a claim's preflight scan finds no matching record
+  (the correlation-pending leg), the group is unknown; the lock key is
+  then the 6 fields `("unavailable", team_id, channel_id,
+  thread_root_ts, responder_bot_user_id, requester_bot_user_id)` —
+  mirroring Discord's `("unavailable", delegation_id)` fallback
+  (CM:2511-2515).
+- **Root serialization lock** — label `dgser`, key = `(team_id,
+  channel_id, thread_root_ts)`. The Slack port of Discord's coarse
+  per-(app, bot, guild, room) referenced-bot-message lock
+  (DOC:166-171; GW:2739-2767): held by the delivery worker for a
+  result-bearing message from before correlation through local delivery
+  and finalize, so snapshot order at the requester equals delivery
+  order. **Deviation D4 (normative):** the Slack key is finer than
+  Discord's room-wide key because the thread root is derivable from the
+  stored event *before* correlation (`thread_ts`), which Discord's
+  reply reference is not (it requires a fetch). Sibling results always
+  share `thread_root_ts`, so the ordering guarantee is preserved; the
+  pilot caveats transfer verbatim: the lock is coarse, queues every
+  result for the same root behind a slow delivery, is not
+  cancellation-aware, and production must replace it with a durable
+  ordered per-root delivery queue before increasing concurrency
+  (DOC:168-171).
+
+**Lock ordering (deadlock freedom, normative):** `dgser` → `dgroup` →
+`dtuple` → `intent`. No code path acquires a higher-rank lock while
+holding a lower-rank one. Python never takes `dgser` or `dgroup`
+(delegate/cancel stay `dtuple`-only, matching Discord where delegate
+takes no group lock — snapshot readiness "neither predicts future
+delegations" DOC:161-163, so sibling materialization needs no group
+serialization).
+
+**Synthesis snapshot fields (additive, on the delegation record).**
+Frozen by Go in the *same atomic rewrite* as the
+`pending → result_claimed` transition (rule 11; CM:2479-2581 persists
+claim + snapshot in one `save_company_delegation`):
+

+      "expected_responder_bot_user_id": "U…"
+    }
+  ],
+  "synthesis_ready": false,
+  "synthesis_snapshot_at": "<RFC3339, == result_claimed_at>"
+}
+```
+
+Decision and justification: the snapshot lives **on the delegation
+record**, not a separate group record — exactly Discord's placement
+(CM:2389-2398). One record, one write gives claim+snapshot atomicity
+under the existing generation counter and tuple lock with no
+two-file-commit protocol; the replay orderer reads it from the records
+it already loads; and a separate group record would need its own
+generation/lock/pruning lifecycle for no additional invariant. Both
+parsers treat the fields as additive: Go's struct-decode ignores
+unknowns and `companyRewriteDelegation` preserves them
+(company_peer.go:222-235); Python's `parse_delegation` must accept and
+pass them through. Pending-entry identity uses the Slack record's field
+names (`expected_responder_agent`, not Discord's
+`expected_responder_name`) plus both the posted `ts` and the derived
+`delegation_key`, so readers never re-derive filenames.
+
+**Receipt store additions (`ingress_receipts.go`, all
+`json:"…,omitempty"`, Phase 1 fixtures unaffected):**
+
+```go
+// Synthesis is the frozen snapshot bytes for a peer_result receipt,
+// copied from the claimed record in the same routing commit that
+// freezes targets, so redrives re-render byte-identical reminder
+// synthesis fields even if the record is later pruned (the same
+// frozen-bytes discipline as Hydration).
+Synthesis json.RawMessage `json:"synthesis,omitempty"`
+// Correlation-park recovery backoff (rule 17 parity). NOTE omitzero,
+// not omitempty: encoding/json's omitempty never elides a struct, and
+// a bogus 0001-01-01 timestamp on every receipt would pollute the
+// cross-language shape (go.mod is go >= 1.24, omitzero available).
+RecoveryAttempts int       `json:"recovery_attempts,omitempty"`
+RecoveryNextAt   time.Time `json:"recovery_next_at,omitzero"`
+RecoveryReason   string    `json:"recovery_reason,omitempty"`
+// AckState is the visible-ack cursor: "" | "eyes" | "done" | "degraded".
+AckState string `json:"ack_state,omitempty"`
+```
+
+### Normative rules ported from Discord
+
+- **S1 — Atomic claim + frozen snapshot (rule 11; CM:2479-2581,
+  2321-2398).** Under `dgroup` then `dtuple`, the claim computes and
+  persists the snapshot with the `pending → result_claimed` transition
+  in one atomic write. Preflight/group-changed handling pins the
+  CM:2510-2526 loop explicitly: scan without locks; derive the group
+  from the matched pending record (or the fallback key on no match);
+  acquire the locks; re-scan; if the tuple's record set or derived
+  group changed, **release both locks, re-derive from the fresh scan,
+  re-acquire, and re-scan** — at most 3 iterations, then park the
+  receipt `correlation_error` (every-sweep cadence, no attempt
+  budget). Never demote a mismatched claim to a frozen `peer_input`:
+  targets freeze at the first routing commit, and a result consumed
+  as peer_input can never claim later.
+- **S2 — Compatible set (rule 12; CM:2268-2318).** A record is
+  *compatible* with a claim's group iff it parses, its group equals the
+  claim's group, its status is `pending` or `result_claimed`, and its
+  age satisfies `-300s <= now - created_at <= ttl_seconds`. The record
+  being claimed is always included (CM:2348-2358). *Responded* =
+  status `result_claimed`. **Deviation D3 (normative, structural
+  equivalence):** Discord's responded statuses are
+  `{result_processing, completed, result_recovery_failed}`
+  (CM:2268-2272) because Discord tracks local result delivery on the
+  delegation record. On Slack, local delivery lives on the result's
+  ingress receipt (Phase 1/2 target states), so `result_claimed` is
+  the single responded status and no
+  `result_processing`/`completed`/`result_recovery_failed` statuses
+  exist. This preserves the reference semantics exactly because
+  readiness explicitly does not assert local delivery success
+  (DOC:161-163; GW:1195-1198).
+- **S3 — Snapshot content (CM:2360-2398).** `compatible_delegation_count`,
+  `responded_delegation_count`, `pending_delegation_count`,
+  `pending_delegations` (the still-`pending` compatible records, sorted
+  by `(created_at, ts)`), `synthesis_ready := compatible > 0 &&
+  responded == compatible`, `synthesis_snapshot_at := result_claimed_at`.
+  The first of two serialized sibling claims is therefore frozen
+  not-ready with one pending sibling; the second is frozen ready
+  (DOC:158-161).
+- **S4 — Frozen snapshots are immutable (rule 11; CM:2528-2566).** A
+  claim replay — same `result_ts` and same nonce against an
+  already-claimed record — returns the stored record and rewrites
+  nothing. A *different* result against a claimed record claims
+  nothing (Phase 2 behavior, now extended: it is peer input, never a
+  second claim). Replay acceptance is time-bounded: the idempotent hit
+  is honored only while `-300s <= now - result_claimed_at <= 7 days`
+  (the receipt-retention constant; `companyPeerEnv` gains a
+  `retention` field plumbed from the gateway's value; CM:2548-2565);
+  outside the window — or when `result_claimed_at` is unparseable (S9
+  fail-closed reads) — the message is ordinary peer input. This
+  amends the unbounded replay match Phase 2c shipped
+  (company_peer.go:469-474). An already-claimed tuple bypasses the
+  `postingIntentExists` check entirely: a lagging `posting` intent for
+  a claimed tuple must never park the message `correlation_pending`.
+- **S5 — Monotonic per-group replay ordering (rule 16; GW:2031-2097;
+  DOC:181-187).** Startup recovery and every sweep pass order replay
+  within a group: receipts whose claimed record has no valid snapshot
+  (legacy/malformed/pruned) first, by `(ReceivedAt, origin ts, receipt
+  id)` — the receipt does not store `result_claimed_at`/result ts, so
+  the received time is the normative stand-in (a deterministic total
+  order over the legacy bucket); then snapshot-bearing receipts by
+  ascending
+  `(responded_delegation_count, synthesis_snapshot_at, result ts,
+  receipt id)`. Slack `ts` ordering is numeric on the two
+  `.`-separated integer components; a malformed ts sorts after all
+  well-formed ts by raw string (a deliberate simplification of GW's
+  `(1, created_at, raw_id)` malformed fallback — both are
+  deterministic total orders). Receipts outside any group keep the
+  store's `(ReceivedAt, Origin.TS)` order (GW:2080-2093 permutes only
+  sibling positions). Chains are partitioned by root triple, coarser
+  than Discord's per-group permutation: multiple groups sharing one
+  root serialize together, which is safe (sorting a superset by a
+  total order preserves each group's relative order) and merely adds
+  cross-group serialization Discord did not impose; pruned-record
+  receipts land in the chain's legacy-first bucket (Discord left them
+  in store order — accepted divergence). Group members are delivered
+  **sequentially by one worker chain** — receipt k must reach a
+  terminal state or a pre-claim park before k+1 starts, per the
+  deliverOutcome contract in 3b — because ordered trigger issuance
+  alone proves nothing under concurrent delivery goroutines.
+- **S6 — Live ordering (DOC:166-171; GW:2739-2767).** The delivery
+  worker takes `dgser` before correlation and holds it through
+  finalize for every *result-bearing* message: bot-authored AND
+  `metadata.event_type == "gc_delegation_result"`. (Discord serializes
+  every referenced bot message because it cannot classify before a
+  fetch; Slack's metadata gate is load-bearing for claim admission —
+  Phase 2 — so only metadata-bearing messages can claim, and gating
+  the lock on it is sound.)
+- **S7 — Parked correlation references with bounded backoff (rule 17;
+  GW:44-46, 1603-1695, 2961-2998).** A receipt parked
+  `correlation_pending` (a result whose tuple has a plausibly
+  in-flight `posting` intent) follows the reference schedule exactly:
+  the park is immediately eligible on the next pass (no initial
+  delay, GW:1603-1613); a redrive that re-ran `resolveResultWake` and
+  found the posting intent STILL in flight counts one attempt and
+  schedules the next at `min(60s * 2^(n-1), 15min)` where n is the
+  failure count — five waits (60/120/240/480/900) — and the receipt
+  goes **terminal** when the attempt count reaches 6: `Status:
+  failed`, `Reason: "correlation_recovery_exhausted"` (Discord's
+  `recovery_failed`), counted in `deliveryFailures`. Correlation-layer
+  I/O or scan ERRORS never consume the budget: they park under the
+  distinct reason `correlation_error` with plain every-sweep cadence.
+  `recoverPending` applies the same `RecoveryNextAt` eligibility as
+  `sweepEligible` (an adapter restart neither bypasses the backoff nor
+  bumps attempts). `parkWithReason`'s idempotent early-return must
+  still commit the attempts++/next-at update for the recovery reasons
+  (explicit edit). A redrive that finds the record materialized
+  (Python's lazy reconciliation ran) claims and delivers normally and
+  clears the recovery fields.
+  **Deviation D5 (normative):** the Slack-born
+  `ambiguous_pending_delegations` park (no Discord analog — Discord's
+  reply reference is unique) uses the same backoff schedule but
+  **never goes terminal**: after 6 attempts it keeps retrying at the
+  15-minute cap. Ambiguity means the one-pending-per-tuple invariant
+  was breached; terminalizing would silently drop a trusted result,
+  while the non-terminal park stays visible on `/healthz` and is
+  operator-resolvable (`delegate --cancel`, or `company-redrive` after
+  repair). The retention sweep never deletes non-terminal receipts
+  (Phase 1b contract), so correlation/ambiguity parks are exempt from
+  the 7-day retention by construction; the resulting
+  unbounded-but-healthz-visible accumulation for never-resolved
+  ambiguity is the accepted tradeoff (noted in Deferred).
+  `author_resolution_pending` and `parked_no_directory_room` keep
+  their Phase 1/2 every-sweep cadence (no backoff), as on Discord.
+- **S8 — One-hop enforcement (rule 9; GW:1174; DOC:195-196;
+  discord delegate help.md:10-12; discord_chat_delegate.py:83-84).**
+  Strict reference parity: `run_delegate` proceeds only when the
+  resolved turn's kind is `ambient` or `targeted` (the human-rooted
+  kinds — Discord requires `discord_human_message` context) and
+  hard-errors on `peer_delegation`, `peer_input`, and `peer_result`
+  alike. A delegated recipient may `reply-current` a result but may
+  not redelegate; a requester issues every intended sibling delegation
+  from its human-rooted turn(s) *before* waiting — a frozen ready
+  snapshot cannot account for a delegation created later
+  (discord-v0.template.md:68-72), and delegating from a result turn
+  would enable a second synthesis to the same root. Bot-rooted
+  delegation chains (delegating from a `peer_input` turn whose derived
+  root is a bot message) are likewise excluded. The rendered reminder
+  for every peer kind gains the line `peer_redelegation: forbidden`,
+  now consistent with the verb-level gate.
+- **S9 — Tri-state correlation reads (rule 18; CM:2147-2160;
+  GW:2919-2959).** Already the Phase 2 posture (parse-failure =
+  not-live, never claimable, never rewritten); Phase 3 extends it to
+  snapshot reads: an unparseable or invalid stored snapshot is
+  *unavailable* (S10), never an error that blocks delivery, and never
+  rewritten by replay.
+- **S10 — Snapshot validation (CM:2401-2476).** Both languages ship
+  the same normalizer: a stored snapshot is *available* iff
+  `synthesis_state_version == 1`, `synthesis_state_available == true`,
+  all three counts are non-negative ints with `responded + pending ==
+  compatible` and `compatible > 0`, the pending list length equals
+  `pending_delegation_count` with unique non-empty `delegation_ts`,
+  `synthesis_snapshot_at` is non-empty, and the stored
+  `synthesis_ready` equals the recomputed `compatible > 0 && responded
+  == compatible && pending == 0`. Anything else normalizes to the
+  unavailable shape (version 0, zero counts, empty list, ready false).
+  Normalization is STRICT and identical across languages: no whitespace
+  trimming anywhere, and `synthesis_state_version` plus all three
+  counts must be exact JSON integers — bool, float (including `1.0`),
+  and numeric-string forms are invalid on both sides (Python note:
+  `bool` is an `int` subclass and must be explicitly excluded). The
+  envelope and the Python gate consume only the normalized form.
+
+### Synthesis envelope and the reply-current gate
+
+`renderCompanyReminder` (company_hydration.go:185-231) gains, for
+`kind == peer_result` only, the Discord synthesis block rendered from
+the receipt's frozen `Synthesis` bytes (GW:1177-1200):
+
+```
+synthesis_state_version: 1
+synthesis_state_available: true
+compatible_delegation_count: 2
+responded_delegation_count: 2
+pending_delegation_count: 0
+pending_delegations_json: []
+synthesis_ready: true
+synthesis_ready_meaning: all_currently_materialized_compatible_delegations_have_durably_claimed_slack_results
+synthesis_ready_is_local_delivery_success: false
+```
+
+Every interpolated value passes `neutralizeMarkupBoundaries`; the
+snapshot is normalized (S10) before rendering, so a malformed frozen
+blob renders the unavailable shape rather than failing delivery.
+
+`post_peer_synthesis` (slack_company_outbound.py:1648) gains the gate:
+it loads the record at `turn["delegation_key"]`, normalizes its stored
+snapshot (S10), and
+
+- *available and ready* → proceed;
+- *available and not ready* → hard error (exit 1) listing each pending
+  delegation (`expected_responder_agent`, `delegation_ts`) and the two
+  remedies — wait for the remaining sibling result wake, or
+  `gc slack delegate --cancel --to <agent>` for a dead sibling (which
+  expires it out of the compatible set, so the *next* claim freezes
+  ready) — unless the new flag `--allow-partial` is passed, which
+  proceeds and records `"allow_partial": true` in the report;
+- *unavailable* (legacy/malformed/pruned record) → proceed with a
+  stderr warning (never wedge on cosmetic-state corruption).
+
+**Deviation D2 (normative):** Discord's "synthesize only on
+`synthesis_ready: true`" is prompt-level instruction in the envelope
+template (context-map rule 11, TPL:68-75). Slack enforces it at the
+verb because Python has local read access to the frozen record —
+Discord's CLI did not re-read the snapshot at reply time. The
+`--allow-partial` escape preserves agent agency for deliberately
+partial synthesis. Note the composed Phase 2 behavior: the pointer file
+is overwritten by each newer wake, so an agent acting on a stale
+`--origin-ts` pinned turn sees that claim's frozen (not-ready)
+snapshot and is correctly refused; the final sibling's wake carries the
+ready snapshot.
+
+### Redrive parity (`retry-peer-fanout` → `company-redrive`)
+
+What Discord's `retry-peer-fanout` provides (commands/retry-peer-fanout/
+help.md; CM:6399-6491): operator redrive of failed peer targets from a
+saved publish record, without reposting to the provider, reusing the
+same deterministic idempotency keys, with target selection. On Slack
+the *automatic* half already exists structurally — frozen targets,
+same-key sweep retries, bounded attempts (Phase 1d/2c) — so Phase 3
+adds only the operator half, receipt-native:
+
+```text
+gc slack company-status [--receipt <id>] [--origin <team>:<channel>:<ts>] [--root <team>:<channel>:<root_ts>]
+gc slack company-redrive (--receipt <id> | --origin <team>:<channel>:<ts>) [--target <session>]... [--include-failed]
+```
+
+The legacy `gc slack retry-peer-fanout` (extmsg audit-event path) is
+untouched; overloading its name onto receipt semantics would conflate
+two delivery systems, hence the new verb names.
+
+Ownership: the receipt store has exactly one writer (Go, generation
+CAS), so Python must not rewrite receipts. The adapter's internal
+listener (main.go internal mux / `LISTEN_INTERNAL` / `serviceSocket`
+UDS) gains two company endpoints, and the Python verbs are thin
+clients resolving the same env vars — the same pattern as Discord's
+CLI operating on state its own process family owned:
+
+- `GET /internal/company/receipts?origin=…|root=…|status=…` — bounded
+  JSON listing: receipt id/origin/status/reason/recovery fields,
+  per-target state (session, kind, status, attempts, detail,
+  delegation_key), ack state.
+- `POST /internal/company/redrive` body `{"origin": {…}, "targets":
+  ["s1", …], "include_failed": true|false}` — under the receipt's
+  single-flight + generation commit (single-flight held elsewhere →
+  409, the verb retries). The `receipt` id, when supplied, is
+  pattern-validated before any path use (400 otherwise). Two legs:
+  (1) receipts **with frozen targets**: selected targets (default:
+  all **bound** `failed` targets; `--target` filters;
+  `--include-failed` is required to touch a target whose Detail
+  begins `attempts_exhausted`) are reset to `pending` with
+  `Attempts: 0`, `Detail: "operator_redrive"`, the **same recorded
+  IdempotencyKey** (never re-derived), receipt status back to
+  `routing`, recovery backoff fields cleared, then `triggerDelivery`.
+  A `failed` target frozen **unbound** (`Session == ""`) is
+  re-resolved at redrive time from its recorded `Agent` name against
+  the CURRENT bindings snapshot — the binding-repair recovery path;
+  on success it gains its session and a normally-derived
+  IdempotencyKey; still-unbound targets are reported as unresolvable
+  in the response. An empty reset that leaves
+  recoverable-but-unbound targets is an explicit 422
+  (`reason: "unresolved_targets"`) — never a success-shaped empty
+  reset hiding lost data; benign empties (all delivered, `--target`
+  miss, `attempts_exhausted` without `--include-failed`) remain 200
+  with an empty reset so status checks do not error.
+  (2) receipts **with no recorded targets** (the
+  `correlation_recovery_exhausted` / parked states this verb is the
+  designated recovery for): reset Status to `received`, clear Reason
+  and the recovery fields, then `triggerDelivery` so first-routing
+  resolution re-runs from correlation. Terminal-and-swept receipts
+  (past 7-day retention) are gone; the endpoint returns 404 and the
+  verb says so.
+
+`company-status` additionally assembles Python-owned reads (delegation
+records grouped by synthesis group with normalized snapshots, stale
+`posting` intents) so one command shows a wedged flow end to end.
+Help text carries the Discord caveat forward: an
+`attempts_exhausted` target's earlier timeouts had unknown outcomes and
+gc's idempotency cache is best-effort — check the target session
+transcript before `--include-failed` (Discord help.md:9-16).
+
+### Visible-ack reactions (config-gated)
+
+Actor: the **switchboard** token — it owns admission and the receipt
+lifecycle, `reactions:write` is already in its manifest
+(manifest/app.json:34), and per-agent tokens must not react to
+messages their agent never saw. Gate: env var
+`SLACK_COMPANY_VISIBLE_ACKS` (unset/empty/`0` = off, default; anything
+else = on), resolved in `main.go` alongside the other company env
+overrides. All ack traffic is best-effort and asynchronous — it runs
+inside the delivery worker, never the HTTP handler (the 3-second ack
+budget is for admission), never changes receipt status, and never
+counts as delivery failure.
+
+Lifecycle hooks in `deliverReceipt`, keyed off the durable `AckState`
+cursor so redrives are idempotent:
+
+1. First delivery attempt for a receipt with `AckState == ""` →
+   `reactions.add eyes` on the origin message; success or
+   `already_reacted` → `AckState: "eyes"`.
+2. Terminal `delivered` → `reactions.remove eyes` (best-effort) +
+   `reactions.add white_check_mark`; → `AckState: "done"`.
+3. Terminal `failed` → the concise switchboard reply into the
+   message's thread root posts **exactly once** (`thread_ts =
+   deriveHumanRootTS`, entity-escaped, no live mentions, body exactly
+   `delivery failed for receipt <id>`), committed as the durable
+   intermediate cursor `AckState: "warned"` in the same receipt
+   update; then `reactions.remove eyes` (best-effort) +
+   `reactions.add warning` advance to `AckState: "done"`. Sweep-heal
+   of a `"warned"` receipt retries ONLY the reactions — a
+   rate-limited ⚠️ can never re-post the reply.
+4. Terminal `no_delivery` → `reactions.remove eyes` only (a green
+   check on a message that woke nobody would misreport); →
+   `AckState: "done"`.
+
+Error taxonomy (normative): `already_reacted` (and `no_reaction` on
+remove) = success; `too_many_emoji`, `too_many_reactions` =
+**silent degradation** — `AckState: "degraded"`, one log line, no
+further ack calls for this receipt; `ratelimited` and transient
+HTTP/network errors leave `AckState` unchanged; any other definitive
+error degrades. Because terminal receipts are never redriven, stranded
+terminal acks are **sweep-healed**: each sweep's retention scan runs
+`applyTerminalAck` for terminal receipts whose `AckState` is `"eyes"`
+or `"warned"` (bounded, within retention; the `"warned"` cursor makes
+the failure reply once-only) — `reactions.remove` is Tier 2 (20+/min),
+tighter than add's Tier 3, so rate-limited terminal acks are the
+expected case, not a corner. A crash between the finalize commit and
+the ack commit still leaves an at-most-once window (👀 may persist
+briefly until the next sweep) — acceptable under the cosmetic
+contract. Ack commits go through the normal generation-bumping receipt
+Update and therefore refresh `UpdatedAt` (they extend the stale-claim
+window `sweepEligible` reads — documented, accepted). Implementation
+reuses the existing reactions client behind the internal `/react`
+endpoint rather than adding a second Slack reactions POST path. The
+emoji are pinned: `eyes`, `white_check_mark`, `warning`. The durable
+receipt, not the emoji, stays authoritative; no `/healthz` surface is
+added for acks (they are cosmetic by contract).
+
+### `/healthz` additions
+
+One line: `company_correlation_parked=<n>` — receipts currently parked
+with reason `correlation_pending` or `ambiguous_pending_delegations`
+(computed in the existing sweep scan). The Phase 1 test pinning the
+`/healthz` shape is updated in the same change.
+
+### Sub-phase decomposition
+
+3a and the ack half of 3b are independently implementable after Phase
+2; 3b's ordering work builds on 3a's snapshot reads; 3c's verbs need
+3b's endpoints.

+
+```go

+
+Edits: `recoverPending` and `sweepOnce` route through
+`orderPendingForReplay` (chains sequential, rest concurrent as today);
+`parkWithReason` increments/schedules recovery fields for the two

+

+60/120/240/480/900, terminal `correlation_recovery_exhausted` at
+attempt 6 (the 15-min cap continues indefinitely only for D5's
+ambiguous park); attempts are scoped per recovery reason — a reason
+transition resets the counter, and `correlation_error` never counts;
+park resolved on attempt 3
+claims and delivers exactly once and clears recovery fields; ambiguous
+park never terminal, capped cadence (D5); redrive endpoint resets only
+selected targets, preserves recorded IdempotencyKey byte-for-byte,
+`attempts_exhausted` requires `include_failed`, 404 past retention;
+ack lifecycle: gate off = zero Slack calls; 👀→✅, 👀→⚠️+threaded
+receipt-id reply, no_delivery removes only; `already_reacted` =
+success; `too_many_emoji` degrades silently and permanently; ack
+failure never blocks or fails delivery; `compareSlackTS` table.
+
+#### 3c — Python gates, verbs, interop + acceptance proofs (`scripts/slack_company_outbound.py`, new `scripts/slack_company_admin.py`, `scripts/slack_chat_reply_current.py`; command wrappers `company-status`, `company-redrive` (3-file convention); `tests/…`; fixtures)
+
+```python
+# slack_company_outbound.py
+def synthesis_group(record: dict) -> tuple[str, ...] | None      # 5-tuple or None
+def synthesis_state(record: dict) -> dict                        # S10 normalizer
+def dgroup_lock_name(*fields: str) -> str                        # parity only, never taken by Python
+# post_peer_synthesis(...) gains allow_partial: bool = False and the D2 gate
+# run_delegate(...) gains the S8 one-hop error
+
+# slack_company_admin.py
+# The internal listener is a UDS (GC_SERVICE_SOCKET, primary
+# proxy_process mode — LISTEN_INTERNAL is ignored when it is set) or a
+# loopback TCP address. A base-URL string cannot express the UDS case,
+# so the client is a connection factory: an http.client.HTTPConnection
+# subclass dialing GC_SERVICE_SOCKET when set, else TCP to
+# LISTEN_INTERNAL (default 127.0.0.1:8766). GC_SERVICE_SOCKET wins.
+def internal_connection() -> http.client.HTTPConnection
+def cmd_company_status(argv) -> int
+def cmd_company_redrive(argv) -> int
+```
+
+`reply-current` passes `--allow-partial` through to
+`post_peer_synthesis`. Fixture additions under
+`tests/fixtures/company/`: a claimed delegation record with frozen
+snapshot (golden bytes both suites re-derive), a not-ready snapshot, an
+invalid-snapshot record normalizing to unavailable, and lock-filename
+parity pins for `dgroup` (5-field and fallback keys) and `dgser` —
+both languages must derive identical `.lock` names, verified like
+Phase 2d's `dtuple-3a4b34ac4caada68.lock`. Interop: the Go suite
+claims (freezing a snapshot) over records generated by the real Python
+paths; the Python suite validates and gates on those exact bytes.
+
+Tests (3c): gate table — ready posts, not-ready exits 1 listing
+pending siblings, `--allow-partial` posts with the report flag,
+unavailable warns and posts; cancel-then-ready flow (cancel a dead
+sibling, next claim freezes ready — proven against Go-claimed bytes in
+interop); one-hop matrix per S8: delegate errors on `peer_delegation`,
+`peer_input`, AND `peer_result` turns alike, proceeds only on
+`ambient`/`targeted`;
+`company-status` renders groups/snapshots/parks/stale intents from
+mixed fixtures; `company-redrive` client (HTTP mocked) passes
+targets/include_failed and surfaces 404; `parse_delegation`
+passes snapshot fields through unmodified (additive-field tolerance).
+
+**Acceptance proofs (automated; the Phase 3 acceptance gate,
+mirroring DOC:239-257).** The phase is done only when these pass:
+
+1. Sibling freeze: requester delegates to two responders; concurrent
+   result claims serialize under `dgroup`; first snapshot not-ready
+   with one pending sibling, second ready; replay of either rewrites
+   neither (DOC:158-163).
+2. Restart ordering: kill the adapter mid-flight with both results
+   claimed and undelivered, shuffle delegation-file discovery order;
+   the requester observes the two peer_result wakes in snapshot order,
+   and durable ingress idempotency absorbs a repeated replay
+   (DOC:181-187).
+3. Live ordering: two results arriving concurrently deliver to the
+   requester in claim order under `dgser` (DOC:166-171).
+4. Correlation park: a result racing its delegation's `posting` intent
+   parks `correlation_pending`, claims exactly once after
+   reconciliation, and an unresolvable park terminalizes after 6
+   backed-off attempts (rule 17).
+5. Synthesis gate: reply-current's synthesis leg refuses on not-ready
+   listing the pending sibling; after `delegate --cancel` of that
+   sibling the next claim is ready and synthesis posts to the human
+   root with no live mentions.
+6. One-hop: `delegate` is rejected from `peer_delegation`,
+   `peer_input`, and `peer_result` turns alike and proceeds from
+   `ambient`/`targeted`; every peer reminder carries
+   `peer_redelegation: forbidden`.
+7. Acks: everything above runs identically with acks off (default);
+   with acks on, 👀/✅/⚠️ follow the lifecycle, `already_reacted` is
+   success, `too_many_emoji` degrades silently, and no ack outcome
+   changes any receipt or delegation state.
+8. Redrive: an `attempts_exhausted` target redriven via
+   `company-redrive --include-failed` delivers once with the original
+   Idempotency-Key, and a target-less `correlation_recovery_exhausted`
+   receipt redriven via the same verb re-enters correlation and
+   delivers.
+9. Replay window: a claim replay inside the 7-day window returns the
+   stored claim unchanged; the same replay past the window delivers as
+   ordinary peer input and rewrites nothing (the S4 amendment of
+   Phase 2 behavior, proven at the gate so it cannot be silently
+   dropped).
+
+The live pilot proof is Discord's, on Slack: one human request, two
+visible sibling delegations, two visible results, one synthesis to the
+human root — every wake exactly once, restart in the middle of the
+result phase, and no credential, GitHub, infrastructure, or mail
+mutation (DOC:253-257).
+
+### Deferred from Phase 3
+
+- A durable ordered per-root delivery queue replacing the `dgser`
+  advisory lock and replay chains (required before raising concurrency
+  or delivery latency — DOC:168-171 carries the same production
+  boundary).
+- Cross-root ordering guarantees (unrelated roots stay
+  discovery-ordered, as on Discord).
+- Ack re-assertion after a human removes the switchboard's reaction,
+  per-agent ack identities, and any ack observability surface.
+- Synthesis groups spanning multiple rooms or requester sessions
+  (out of contract by construction of the group tuple).
+- Automatic un-terminalizing of `correlation_recovery_exhausted`
+  receipts (operator `company-redrive` is the recovery path).
+- Bounding the accumulation of never-resolved
+  `ambiguous_pending_delegations` parks (exempt from retention by the
+  non-terminal rule; visible on `/healthz`; operator-resolvable — an
+  automatic bound would reintroduce the silent drop D5 exists to
+  prevent).
+- The ledger-backed exactly-once upgrade (Phase 5) and per-agent DMs
+  (Phase 4) are unchanged by this phase.
+
+## Phase 4 — per-agent DMs
+
+`message.im` + `im:history` per agent identity app against the shared
+events endpoint. Signature verification binds the claimed app: resolve the
+app record by `(team_id, api_app_id)` and verify the HMAC against that
+record's secret, failing closed on mismatch (trial-HMAC fallback only for
+legacy single-app installs). DM admission into the same receipt store with
+`(team_id, dm_channel_id, ts)` keys; allowed-human policy; DM-bound
+singleton sessions; bot-authored DMs deliver nothing; acceptance rule 12.
+
+DM session binding should ride the extmsg fabric's `dm` conversation
+primitives rather than a pack-local registry: a `ConversationRef{Kind:
+dm}` bound 1:1 to the agent's session is an exact fit for the fabric's
+one-active-binding-per-conversation model and gives durable,
+restart-surviving bindings via the controller-owned bead store
+(`engdocs/design/external-messaging-fabric.md` in gascity core; the
+fabric's Phase-1 single-writer rule means the pack drives this through
+the typed API only). Decide at Phase 4 design time; the room-side
+deterministic wake set stays pack-owned regardless — the fabric's
+member-fanout and group/launcher routing must NOT be adopted for rooms
+(all-members fanout with mention annotation is the prompt-trusted
+suppression model this design replaced).
+
+## Phase 5 — ledger integration
+
+When the gascity durable-request-ledger lands: swap local admission for
+`POST /v0/city/{city}/extmsg/request-receipts` + receipt-lookup recovery,
+implement the projector-callback UDS contract and publish-intent outbox
+against the ledger API, adopt the cross-repo wire fixture. This is an
+explicit state-mapping exercise — the adapter journal adopts the Slack
+companion's six states (`spooled`, `admitting`, `core_bound`,
+`body_redacted`, `rejected`, `quarantined`; `core_bound` is the
+redaction fence — see phase5-ledger-readiness.md, which supersedes the
+earlier three-state note and records the 15-route surface, the
+no-If-Match header protocol, and the rule that DTOs are generated from
+the Slice 20 OpenAPI artifact, never hand-written) — and the ledger's
+receipts never carry raw bodies, so the inner-event payload moves to a
+spool-side body store (shipped ahead of the ledger as the Phase 5
+readiness increment). The Phase 1 origin-key discipline and
+ordering are chosen so the swap does not change pack-observable routing
+semantics; true end-to-end exactly-once delivery arrives here.
+
+Transport note (researched 2026-07-17, gascity core): the supervisor's
+typed control plane is HTTP+SSE only — its two websocket surfaces
+(t3bridge runtime client; opaque `/svc/*` proxy passthrough) reach
+neither orders nor conversations, and orders are named trigger→action
+definitions, the wrong altitude for per-wake delivery. The one
+pre-ledger hardening candidate is migrating company wakes from
+`POST /v0/city/{city}/session/{id}/messages` (202-queued, 30-min
+in-memory idempotency) to `POST /v0/city/{city}/extmsg/inbound`
+(durable bead-backed transcript persisted before session read, typed
+receipt with transcript entry id, principled 4xx-permanent /
+5xx-retryable contract). GATE: extmsg's inbound `DedupKey` is
+currently a no-op in core (type-defined, never consumed —
+`internal/extmsg/types.go`), so gc-side redelivery dedup is not real
+yet and a retried POST would duplicate the turn; do not migrate until
+a DedupKey consumer lands in core or the ledger supplies it. Also
+worth borrowing at ledger time: the orders tracking-bead pattern
+(synchronous durable marker before dispatch, label-keyed dedup) as
+the request-ledger row template.

+# Slack Company Rooms
+
+## Status
+
+Draft v2 for review, 2026-07-17. Successor to the Discord company-rooms pilot
+(accepted 2026-07-15, `discord/docs/company-rooms.md` on
+`feat/discord-company-rooms`); targets the same end state on Slack
+infrastructure with two scope changes: durable event admission is the
+foundational layer rather than a later reliability patch, and per-agent DMs
+are in final scope (delivered in a staged phase). v2 incorporates a
+four-lens adversarial design review.
+
+## Objective
+
+Model Slack channels as visible company rooms. Most agents may be present in
+a room, while only a configured subset wakes for ordinary human conversation.
+Native Slack mentions of real per-agent bot users provide directed activation
+across city boundaries.
+
+Slack is the visible cross-city transport; it is not an authority or
+credential broker. The design must remain portable to Gasworks/Crucible.
+
+Every admissible company-room event is durably recorded and deduplicated
+before the transport is acknowledged. Delivery is redrivable and
+restart-safe; queue saturation is backpressure, never silent loss. Delivery
+to sessions is at-least-once with receipt-side suppression — duplicates are
+possible only in a narrow, documented crash window until the city-level
+durable-request-ledger lands (Phase 5). Traffic outside imported company
+rooms keeps the legacy pipeline unchanged.
+
+## Terms
+
+- **Switchboard**: the slack-full adapter's Slack app for a visibility
+  boundary. It subscribes to room message events and is the single admission
+  owner for company-room traffic.
+- **Agent identity app**: a minimal Slack app for one named agent. Its bot
+  user is the agent's real, mentionable `<@U…>` identity and its bot token is
+  the agent's outbound sending identity. In the rooms phases it has no event
+  subscriptions; the DM phase adds `message.im`.
+- **Member**: a directory-listed agent that may be explicitly activated in a
+  room. Membership does not cause the session to run for every message.
+- **Ambient wake**: a member that receives a human message containing no
+  native mention of a company agent.
+- **Thread ambient wake**: a member whose authenticated agent identity has
+  already posted in a thread and therefore receives later untagged human turns
+  in that same thread.
+- **Mention wake**: a member that receives a message whose native mention
+  tokens include that member's registered bot user ID.
+- **Delegation**: a visible, directed company-bot message created with
+  `gc slack delegate` and durably correlated to its expected responder.
+- **Result**: a visible threaded reply from the expected responder to a
+  recorded delegation.
+- **Receipt**: the durable ingress record created for an admissible
+  company-room event before the HTTP acknowledgment to Slack.
+
+## Topology
+
+One switchboard app per visibility boundary receives every room event and
+enforces routing exactly once. One agent identity app per named agent
+provides the mentionable identity and outbound sender. A versioned company
+directory binds names to Slack IDs and rooms to wake policy; a separate
+company-bindings registry binds (room, agent) pairs to local sessions.
+
+For roughly 16 agents this is ~17 installed apps. Slack Free caps custom
+apps at 10 workspace-wide; on paid plans bots are not billed member seats
+(Slack usage-limit and fair-billing help articles). A three-app pilot
+(switchboard, two agents) fits a Free workspace if slots remain.
+
+The switchboard model satisfies the durable-request-ledger drafts'
+single-admission-owner constraint: per-agent apps observe nothing in rooms,
+so one event stream exists per visibility boundary and one receipt per
+message. If an enclave must not be visible to the shared switchboard, that
+enclave gets its own switchboard app and directory.
+
+## Membership and Provisioning
+
+Slack delivers `message.channels` / `message.groups` events only for
+channels the app's bot user has joined, and `chat.postMessage` into a
+channel requires membership (private channels always; public unless
+`chat:write.public`, which this design does not use so that private rooms
+behave identically). Membership is therefore part of the room contract:
+
+- The switchboard bot and every directory member's bot must be invited to
+  each directory room. A directory room the switchboard has not joined
+  produces zero events — an invisible failure unless surfaced.
+- `gc slack import-company-directory` and `gc slack peers` verify
+  switchboard membership per room (`conversations.info` /
+  `conversations.members`; scopes `channels:read`, `groups:read` added to
+  the switchboard manifest), best-effort and warnings-only. In Phase 1 the
+  adapter does not re-verify membership on directory reload — reload-time
+  verification is a Phase 2 addition; until then, re-running `peers` after
+  membership changes is the check. The adapter's sole status surface is
+  `/healthz` detail (there is no separate gateway status payload in this
+  pack).
+- Agent identity apps are provisioned from a manifest template: bot user,
+  `chat:write`, App Home Messages tab enabled
+  (`app_home.messages_tab_enabled: true`,
+  `messages_tab_read_only_enabled: false` — required before the DM phase
+  can work at all), no event subscriptions until the DM phase adds
+  `message.im` + `im:history`. Provisioning harvests each `app_id` and
+  `bot_user_id` into the directory TOML and registers each signing secret
+  with the adapter's multi-secret verification.
+
+## Directory Contract
+
+The company directory is non-secret, versioned data imported into each city.
+It is stored separately from mutable Slack app configuration (its own
+registry file, not `apps.json`) so config commands cannot erase it. It
+contains no tokens.
+
+```toml
+schema_version = 1
+
+[[agents]]
+name = "ollie"
+app_id = "A0AAAAAA1"
+bot_user_id = "U0AAAAAA1"
+
+[[agents]]
+name = "riley"
+app_id = "A0AAAAAA2"
+bot_user_id = "U0AAAAAA2"
+
+[[rooms]]
+name = "orchestrator-team"
+team_id = "T0AAAAAAA"
+channel_id = "C0AAAAAAA"
+members = ["*"]
+ambient_wake = ["ollie"]
+mention_wake = ["*"]
+```
+
+Agent names and room names are lowercase stable slugs. `app_id`,
+`bot_user_id`, room names, and `(team_id, channel_id)` pairs are unique. A
+duplicate or unknown reference makes the directory invalid; routing fails
+closed. `members = ["*"]` means all listed agents; `mention_wake = ["*"]`
+means all members are mention-eligible; wildcards are forbidden in
+`ambient_wake`. Wake lists must be subsets of members.
+
+Delivery additionally requires a **singleton company binding**: the
+company-bindings registry maps each (room, agent) pair to exactly one named
+session, written by `gc slack bind-company-agent`. A binding may be
+**city-qualified** (`--city`): the target session lives in a different gc
+city on the same host — the switchboard remains the single admission
+owner and delivers wakes to that city's supervisor API (configured via
+`SLACK_COMPANY_CITY_APIS`), matching the live org's one-team-per-city
+topology. A woken agent with no binding is a recorded delivery failure
+for that target, never a legacy fallback. The directory cannot launch
+arbitrary sessions.
+
+The adapter keeps normalized in-memory snapshots of both registries. They
+are staged and committed **outside** the existing six-registry atomic
+reload: a valid replacement becomes the new snapshot; a malformed or
+semantically invalid replacement is reported and the last-known-good
+snapshot is retained, without blocking the other registries' reload (this
+mirrors the Discord reference and preserves the isolation rationale). On a
+cold start with a missing or invalid directory, company routing is empty
+and the adapter keeps running — the load error is surfaced, legacy rooms
+and DMs continue through their existing paths, and pending company receipts
+are parked, not dropped.
+
+## Durable Admission
+
+This is the foundational layer. It applies to Slack Events API POSTs whose
+`(team_id, channel_id)` matches an imported company room — and, in the DM
+phase, per-agent DM conversations. All other traffic keeps the legacy
+ack-first path byte-for-byte.
+
+Order of operations for a company-room event POST:
+
+1. Verify the Slack signature (existing multi-secret trial HMAC, ±5 min
+   replay window, fail closed).
+2. Synchronously decode the event envelope: outer `api_app_id`, `event_id`,
+   `team_id`, and the full inner `event` object; capture
+   `x-slack-retry-num` / `x-slack-retry-reason` from the request headers.
+3. Admissibility gate — an explicit subtype allowlist: subtype absent,
+   `file_share`, `thread_broadcast`, or `bot_message`. Everything else
+   (`channel_join`, `channel_topic`, hidden edit/delete records,
+   `url_verification` handshakes, unsupported event types) is acknowledged
+   with HTTP 200 and creates no receipt. The switchboard's `app_mention`
+   copies of company-room messages are likewise owned by the company path
+   and acknowledged without a receipt — the `message.channels` copy is
+   the canonical admitted event — so they never reach legacy dispatch. An event with no stable
+   `(team_id, channel_id, ts)` identity is logged and dropped with HTTP
+   200 — never 5xx, which would burn Slack's retry budget on an unkeyable
+   event.
+4. Compute the canonical origin key `(team_id, channel_id, ts)`. `ts` is
+   unique per channel; the observing app is never a key input.
+5. Look up the receipt store. A duplicate origin returns HTTP 200
+   immediately; `x-slack-retry-num` redeliveries terminate here.
+6. Create the receipt durably and atomically — claim and content in one
+   step: the full receipt (including the complete inner event and outer
+   identifiers, which later routing and crash replay require) is written
+   to a temp file, fsynced, then hard-linked to its final origin-keyed
+   name; `EEXIST` means duplicate. An existing-but-unparseable receipt is
+   quarantined (`*.corrupt`) and the claim retried once. This is the
+   admission linearization point; there is no window in which a claim
+   exists without its content.
+7. Return HTTP 200 — a local disk append fits far inside Slack's
+   three-second budget.
+8. If persistence fails, return HTTP 503 **without** `x-slack-no-retry`.
+   Slack redelivers (~immediately, +1 min, +5 min). **Enabling the Delayed
+   Events option on the switchboard app is a required operator step**: it
+   extends redelivery to hourly retries for 24 hours, which is what makes
+   a receipt-store outage recoverable rather than lossy. Residual loss
+   windows remain and are accepted, documented risk: an outage longer than
+   24 hours, or Slack auto-disabling the subscription (>95% failures over
+   60 minutes at ≥1,000 events/hour — below that volume Slack does not
+   auto-disable). The receipt store exposes a write-failure counter in
+   `/healthz` detail; that counter is the paging hook, and the re-enable
+   path (app config → Event Subscriptions) is part of the operator
+   runbook. If the receipt store cannot be initialized at startup, the
+   switchboard runs degraded: company-room admissible events receive 503
+   (never legacy delivery) and `/healthz` reports the store error until
+   the store recovers.
+9. Routing and delivery proceed asynchronously after the acknowledgment.
+   The wake set is computed once, at first delivery, and frozen into the
+   receipt's per-target records under keys
+   `ingress:<id>:target:<session>`; redrives drive the recorded targets
+   and never recompute the route. Each session submission carries its key
+   as an `Idempotency-Key` header. gc's idempotency cache is best-effort
+   (in-memory, bounded TTL), so the durable receipt is the authority: a
+   target is marked delivered only on gc's acknowledged acceptance;
+   timeouts, 5xx, 408, and 429 stay pending for retry with the same key;
+   a definitive 4xx marks the target failed with the response detail; and
+   retries are bounded by an attempts cap (exhaustion is a terminal,
+   visible failure). The overall guarantee is at-least-once with
+   receipt-side suppression. True end-to-end exactly-once arrives with
+   the ledger integration (Phase 5).
+10. Dispatch saturation is backpressure: the receipt stays pending and the
+    recovery sweep delivers it later. Nothing admitted is ever silently
+    dropped. A receipt whose channel no longer matches any directory room
+    (directory removed, shrunk, or failed to load) is **parked** — left
+    pending with a recorded reason, retried by the sweep, never terminally
+    resolved and never legacy-delivered.
+
+The HTTP 200 is a transport receipt, not a visible acknowledgment. An
+optional, config-gated visible ack adds a 👀 reaction after admission and
+swaps it for ✅ on terminal completion or a concise ⚠️ reply plus receipt
+ID on terminal failure. `reactions.add` returning `already_reacted` is
+treated as success; `too_many_emoji` and similar caps degrade the ack
+silently; the remove+add swap is best-effort cosmetic — the durable
+receipt, not the emoji, is authoritative.
+
+Startup recovery is a barrier scoped to the company path: legacy routes,
+`/healthz`, interactions, and the internal publish listener serve
+immediately; company-room events receive HTTP 503 (retryable) until one
+synchronous scan of pending ingress receipts succeeds. Posting-intent
+recovery is deliberately not part of the adapter barrier: outbound
+intents are owned by the CLI side and reconciled lazily on every company
+verb invocation (against the receipt store, never by reposting), with
+stale intents surfaced on `/healthz` as the operator signal. `/healthz`
+reports barrier state. The periodic sweep starts only after one full
+success and waits one interval before its first scan.
+
+Receipt states are pack-native (`received`, `routing`, terminal
+`delivered` / `no_delivery` / `failed`, with parked-pending as a reason on
+non-terminal receipts). The durable-request-ledger drafts use a different
+taxonomy (`spooled → admitting → core_bound → terminal`); Phase 5 performs
+an explicit state mapping — it is not a rename, and receipts here
+deliberately retain the raw event body (the ledger's receipts do not, so
+Phase 5 splits body storage into a spool-side store).
+
+## Routing Contract
+
+Native company-agent mentions are exclusive. They replace ambient routing
+for that message; they do not add to it.
+
+| Author and message | Sessions woken |
+| --- | --- |
+| Allowed human root, no native company-agent mention | The room's `ambient_wake` members |
+| Allowed human thread reply, no native company-agent mention | The room's `ambient_wake` members plus authenticated prior agent participants in that thread |
+| Allowed human, one or more native company-agent mentions | Only the mentioned, eligible members |
+| Registered company bot, no native company-agent mention | Nobody |
+| Registered company bot with native company-agent mentions | Only the mentioned, eligible members |
+| Unknown bot, webhook/integration, or the switchboard itself | Nobody |
+
+The native mention set of a message is the union of `<@U…>` user elements
+in its `rich_text` blocks and canonical `<@U…>` / `<@U…|label>` tokens in
+its top-level `text`, matched exactly against directory `bot_user_id`s.
+Slack guarantees `rich_text` blocks only for end-user client messages;
+bot-composed messages may carry mentions only as text tokens, so neither
+source alone is sufficient. Plain text that merely resembles `@riley`
+contains no canonical token and never wakes anyone; over-inclusion is
+bounded because a matched ID still passes membership and
+mention-eligibility checks. Multiple eligible mentions wake each named
+receiver exactly once. The v0 delegation command emits one target per
+message so requests and results remain individually correlated.
+
+Thread participation is fail-closed and receipt-backed. An agent joins the
+ambient reader set only after a bot-authored reply in that exact
+`(team_id, channel_id, thread_root_ts)` passes the `bots.info` company-author
+corroboration and the agent is a current room member. Unknown bots, raw
+`user`/`app_id` claims, switchboard posts, root channel posts, and arbitrary
+text cannot enroll a participant. Later untagged human replies retain the
+configured room ambient set and add those participants with wake kind
+`thread_ambient`; a native company-agent mention remains exclusive and adds no
+thread readers. The verified author name is stored on the ingress receipt, so
+participation survives adapter restarts and expires with receipt retention.
+
+Plain text such as `riley` is intentionally not adapter-level addressing. A
+thread participant or configured ambient reader receives that turn and applies
+the agent response policy; an agent outside those reader sets must first be
+introduced with a native Slack mention.
+
+Author classification is fail-closed. A human author has a `user` ID, no
+`bot_id`, and an allowlisted subtype (absent, `file_share`,
+`thread_broadcast`). A bot author (`bot_message` subtype or `bot_id`
+present) must resolve to exactly one registered agent via the documented
+path — `bot_id` through a cached `bots.info` lookup to its `user_id`
+(switchboard scope `users:read`), with the event's `user` field as
+corroboration when present — and ambiguity delivers nothing. Workspace
+webhooks and unregistered integrations are bot messages that resolve to no
+agent: ignored. The switchboard's own posts are ignored except for
+delegation-intent echo reconciliation.
+
+Suppression is deterministic and adapter-side: the switchboard computes the
+wake set from the directory and delivers only to sessions bound in the
+company-bindings registry. Company rooms bypass the legacy path in which
+the channel-bound session receives every message and is prompt-trusted to
+stay silent. All room members may read the Slack transcript; agents that are
+neither configured ambient readers, prior thread participants, nor mentioned
+receive no session turn.
+
+## Context Hydration
+
+Slack is the canonical room transcript. A directed wake includes the
+current message, the verified human root when one exists, and a bounded
+excerpt of recent room messages fetched via `conversations.history` /
+`conversations.replies`, limited by both count and encoded size, and
+labeled untrusted. Failure to fetch history does not broaden routing or
+trust; the current message is delivered with `context_status:
+context_unavailable`, and a verified root is included when it can still be
+fetched independently. The gateway hydrates only sessions actually woken.
+
+## Trust and Authority
+
+Trusted peer ingress requires all of the following:
+
+1. The team and channel exactly match an imported company room and the
+   switchboard's existing allowlist.
+2. The author is a bot resolving to exactly one registered company agent
+   (via `bot_id` → `bots.info` → `user_id` against the directory), with no
+   webhook provenance.
+3. The author is not the receiving agent.
+4. The receiving agent's exact `bot_user_id` appears in the message's
+   native mention set.
+5. Both agents are room members, the receiver is mention-eligible, and the
+   (room, receiver) pair has exactly one session in the company-bindings
+   registry.
+
+Peer input uses `kind: slack_peer_delegation` or `kind: slack_peer_result`;
+it never enters the human-message or generic extmsg path. The body is
+untrusted. The recipient applies its own charter and credential policy; a
+peer cannot widen that charter, grant credentials, or claim human approval
+transitively. The envelope keeps `peer_authority: peer_only` for every peer
+turn and records human linkage separately as `root_provenance:
+human_root_verified`; consumers must not collapse the two.
+
+Slack has no `allowed_mentions` equivalent, so mention discipline is a
+composition contract: company posts use top-level `text` only — never
+`blocks`, never `link_names`, never `parse=full` (defaults only) — and
+agent-supplied bodies are entity-escaped (`&`, `<`, `>`) before posting.
+Under those constraints the service-constructed `<@target>` is the only
+live mention in a delegation and the recorded requester the only live
+mention in a result; bare `@channel` / `@here` / `#channel` text cannot
+become live notifications because automatic parsing is never enabled.
+Synthesis replies to the human root contain no live agent mentions.
+
+## Command Contract
+
+```text
+gc slack import-company-directory --file <rooms.toml>
+gc slack bind-company-agent --room <name> --agent <name> --session <name>
+gc slack peers [--room <name>]
+gc slack delegate --turn-ref <ref> --to <agent> --body-file <path>
+gc slack delegate --turn-ref <ref> --cancel --to <agent>
+gc slack reply-current --turn-ref <ref> --body-file <path>
+```
+
+`import-company-directory` validates and normalizes the TOML, verifies
+switchboard room membership, and atomically replaces the directory
+registry. `bind-company-agent` records the singleton (room, agent) →
+session binding; rebinding replaces, and ambiguity is impossible by
+construction. `peers` reports rooms, members, wake policy, bindings, and
+membership warnings.
+
+Each authenticated reminder carries the room name, team/channel id, origin
+timestamp, human thread root, receipt id, and an opaque `turn_ref`. The
+switchboard persists that turn under `company-current-turn/by-ref/` before
+waking the agent; records are create-once and retained for the same seven-day
+window as ingress receipts. The mutable per-session pointer remains only for
+pre-rollout compatibility. Post-rollout `delegate` and `reply-current` fail
+closed without the reminder's `--turn-ref`, then verify the referenced session,
+agent binding, directory room route, and turn kind before posting. Thus another
+room waking the same named session cannot redirect an in-progress reply or
+delegation; agents never memorize IDs or tokens.
+It durably persists a posting intent before the provider POST
+(prepared → posting → published, bounded attempts, TTL), then posts
+`<@target> …` as the delegating agent's identity app into the human root's
+thread, carrying a content-addressed nonce in Slack message metadata
+(`metadata.event_type: gc_delegation`, nonce in `event_payload`). The
+delegation record — keyed by the posted `(channel, ts)` with the expected
+responder's `bot_user_id` — is materialized before the CLI reports success.
+Crash recovery reconciles unresolved intents against
+`conversations.replies` **with `include_all_metadata=true`** (without it
+Slack omits `event_payload` and reconciliation would miss every nonce);
+reconciliation that cannot find the nonce parks the intent — it never
+reposts on ambiguity, because `chat.postMessage` is not idempotent.
+Metadata is a correlation breadcrumb only — workspace-visible and mutable;
+the durable record remains authoritative and must also match responder,
+workspace, channel, thread root, and recorded Slack `ts`.
+
+On a peer delegation, the reminder's exact
+`gc slack reply-current --turn-ref …` command posts the result into the
+same human-root thread, mentioning only the recorded requester. Slack has
+no nested replies, so a result cannot reference the delegation message
+directly; correlation is by durable record. A claim requires the full
+peer trust checklist plus: the message is in thread `thread_root_ts` and
+authored by the expected responder; its native mentions include the
+recorded requester; and its result metadata matches the record's nonce
+and delegation `ts` — the metadata gate is load-bearing for claim
+admission (a clarifying question or hand-typed post from the responder
+delivers as ordinary peer input and consumes nothing), while authorship
+remains the trust anchor, so metadata alone can never claim. `delegate`
+enforces at most one pending delegation per `(team, channel,
+thread_root_ts, responder, requester)` under a cross-process lock, and
+the turn-bound `gc slack delegate --cancel` recovers a wedged tuple without waiting out
+the TTL. On a peer result, the requester is directed back to the
+verified human root without mentioning ambient or prior peer agents. An
+unmatched reply is never an implicitly trusted result — potentially
+in-flight references are parked for recovery, identifiable replies to
+the switchboard itself are rejected, and other unmatched replies remain
+ordinary peer input.
+
+Multi-specialist synthesis keeps the Discord contract: the requester issues
+every intended sibling delegation before waiting; result claims for the
+same verified human root, requester session, app, and room are serialized
+under one cross-process group lock; each claim freezes a synthesis snapshot
+(compatible and responded counts, pending delegation identities,
+`synthesis_ready`), and replay cannot rewrite a frozen snapshot. V0 allows
+one delegation hop; a delegated recipient may return a result but may not
+redelegate that turn. Self-targeting is rejected.
+
+## Identities and Tokens
+
+Outbound identity is real, not cosmetic: delegations and results are posted
+with the acting agent's own bot token, so the message author *is* the
+mentionable `<@U…>` identity. `chat:write.customize` display overrides
+remain a legacy path for non-company rooms only.
+
+Per-agent bot tokens live outside agent sandboxes in the adapter's secrets
+directory, one file per agent (`secrets/bot-token-<agent>.txt`, 0600 in a
+0700 directory), selected by the directory's agent name at posting time. In
+Crucible, a city-owned Slack service holds token custody and sandboxes
+submit typed delegate/reply requests only. The pilot uses long-lived
+tokens; production enables Slack token rotation (rotated access tokens
+expire every 12 hours) with the gateway refreshing automatically. OpenBao
+references replace token files when the org manifest lands; the directory
+never contains secrets either way.
+
+## Per-Agent DMs
+
+New scope relative to the Discord pilot, which deferred DMs. Delivered as
+the final phase, after room parity.
+
+- Each agent identity app subscribes to `message.im` (scope `im:history`)
+  pointing at the same public events endpoint, with its App Home Messages
+  tab enabled (a hard Slack prerequisite for humans to DM a bot).
+- Signature verification for app-attributed events binds the claimed app:
+  the adapter resolves the app record by `(team_id, api_app_id)` and
+  verifies the HMAC against **that record's** secret, failing closed on
+  mismatch — the multi-secret trial alone proves only that *some*
+  registered app signed the request, which must not let one app's secret
+  admit events into another agent's DM spool.
+- The admission owner for a DM conversation is that agent's own app —
+  exactly one owner per DM, consistent with the single-admission-owner
+  rule. DM events flow through the same durable admission spool with
+  canonical key `(team_id, dm_channel_id, ts)`.
+- Routing: a DM from an allowed human wakes the agent's singleton DM-bound
+  session. Bot-authored DMs deliver nothing in v0 — delegation and results
+  stay visible in company rooms; DMs never carry peer authority.
+- Hydration, receipts, retries, and visible-ack semantics match rooms.
+
+## Reliability and Loop Controls
+
+- Ingress is deduplicated durably by canonical origin key, including across
+  Slack redeliveries and adapter restarts. Receipt retention is 7 days
+  (Discord parity) with a hard floor of 24 hours — terminal receipts are
+  the dedup memory for late redeliveries, so retention below the Delayed
+  Events horizon is rejected.
+- Delivery workers hold an in-process single-flight claim per receipt; the
+  sweep skips receipts claimed recently (stale-reclaim window), and
+  receipt updates carry a generation counter so a lost race is detected,
+  re-read, and merged rather than silently overwritten. All gc submissions
+  on the company path use an HTTP client with an explicit timeout.
+- The startup recovery barrier is company-scoped (legacy serves
+  immediately); posting intents recover before pending ingress; the
+  periodic sweep starts only after one successful pass.
+- Outbound posts go through durable intents created before the provider
+  POST, with CAS-guarded bounded attempts; `rate_limited` responses honor
+  `Retry-After` within those attempts. Non-idempotent posts reconcile
+  against channel history before any repost.
+- Bot messages without a native target mention never ambient-wake agents;
+  unknown bots, spoofed textual mentions, wrong rooms, unbound targets,
+  replays, and ambiguous identities produce no delivery.
+- Requests, results, and delivery failures remain visible in the human
+  root's thread in the company room (`reply_broadcast` is never set, so
+  they do not appear in the channel timeline outside the thread). DMs
+  never substitute for room delivery of delegations or results.
+- The switchboard uses HTTP Events API delivery (the existing public
+  endpoint); Socket Mode is not built for this scope.
+
+## Compatibility and Rollout
+
+Company-room routing is additive and disabled when no directory is
+imported. Legacy human ingress, alias dispatch, rig routing, room launch,
+non-company rooms, and existing bindings retain their current behavior in
+non-company rooms. For imported company rooms, the company path replaces
+legacy fanout deterministically.
+
+Required operator steps beyond pack install: enable Delayed Events on the
+switchboard app; add `channels:read`, `groups:read` (Phase 1) and
+`users:read` (Phase 2) to the switchboard manifest and reinstall; invite
+the switchboard bot and member agent bots to each directory room;
+optionally set `SLACK_SWITCHBOARD_BOT_USER_ID` so the switchboard can
+classify its own posts (empty is safe in Phase 1 — self posts are bots
+and bots wake nobody).
+
+The pilot is a three-app proof in a scratch channel: one human ambient
+request, exclusive `@riley` activation, one visible Ollie→Riley delegation
+with metadata correlation, one visible result, restart recovery mid-flight,
+a Slack redelivery absorbed by the receipt store, and a captured real
+agent-app post event pinning the wire shape the mention extractor and
+author classifier rely on — before creating the remaining identities.
+Partially verified live (2026-07-17, workspace `T0ARJCFV8QL`, via
+`chat.postMessage` + `conversations.history` readback): a real agent-app
+post carries NO `subtype`, has `user`/`bot_id`/top-level
+`app_id`/`bot_profile.app_id` (the classifier's corroboration chain),
+Slack synthesizes `rich_text` mention elements for text-only posts, and
+metadata round-trips on history reads with `include_all_metadata=true`.
+Still pending the deployed events endpoint: metadata embedded in
+`message.channels` event deliveries (load-bearing for receipt-based
+reconciliation).
+
+## Acceptance Gate
+
+Automated tests must prove:
+
+1. An unmentioned human message wakes exactly the configured ambient
+   agents.
+2. A human `@Riley` wakes Riley only, not ambient Ollie.
+3. A trusted Ollie message with a native `@Riley` mention wakes Riley
+   exactly once.
+4. Textual mentions, unknown bots, webhook posts, self messages, wrong
+   rooms, unbound targets, replays, ambiguous identities, and
+   non-allowlisted subtypes (joins, topic changes) deliver nothing.
+5. Riley's threaded result wakes only Ollie and correlates to Ollie's
+   delegation record.
+6. No unmentioned agent message produces ambient delivery or a loop.
+7. A newly mentioned dormant agent receives the current request, verified
+   human root, and a bounded untrusted excerpt without duplicate delivery.
+8. An event admitted but undelivered at an adapter crash is delivered
+   after restart: exactly once when the crash precedes gc submission;
+   at-least-once with receipt-side suppression when the crash falls
+   between submission and the delivery record (the documented duplicate
+   window).
+9. A Slack redelivery (`x-slack-retry-num` ≥ 1) of an admitted event
+   changes nothing and returns 200.
+10. A receipt-store write failure yields non-2xx without
+    `x-slack-no-retry`, increments the write-failure counter, and a
+    subsequent retry admits and delivers once.
+11. A receipt whose room leaves the directory is parked, never terminally
+    resolved, never legacy-delivered, and delivers after the room is
+    restored.
+12. DM phase: an allowed human DM wakes exactly the agent's DM-bound
+    session; bot-authored DMs deliver nothing; DM replays are absorbed; an
+    event claiming agent A's `api_app_id` signed with agent B's secret is
+    rejected.
+
+## Deferred
+
+- Delegation chains longer than one hop.
+- Dynamic discovery of agents or Slack identities.
+- Cross-workspace rooms, Slack Connect, and shared channels.
+- Socket Mode transport.
+- Slack token rotation automation (documented posture; disabled in pilot).
+- Direct integration with the durable-request-ledger `/v0` API (tracked;
+  blocked on those drafts landing in gascity).
+- Credential delegation or transitive human approval.

+# Phase 4 — Per-Agent DMs: Implementation Spec (v2)
+
+Status: revised after four-lens adversarial review (19 confirmed
+findings folded in; review archive: wf_8eac616e-b18). Normative parent:
+`company-rooms.md` (§Per-Agent DMs, acceptance rule 12) and
+`company-rooms-implementation-plan.md` (§Phase 4). Where this spec and
+the parent conflict, the parent wins and this spec must be corrected.
+
+## Goals
+
+A human workspace member DMs an agent's app; the agent's singleton
+DM-bound session wakes with the message, replies through
+`gc slack reply-current`, and the reply appears in the DM as the agent's
+own identity. Bot-authored DMs deliver nothing. All of rule 12 holds:
+replays absorbed, cross-app signature spoofing rejected, exactly the
+DM-bound session woken.
+
+## Resolved design decisions
+
+### D-DM1: DM session binding is pack-local, not extmsg-fabric
+
+`dm_bindings.json` in the company state dir, sibling of
+`company_bindings.json`, `schema_version: 1`:
+
+```json
+{"schema_version": 1,
+ "dm_bindings": [{"agent": "ollie", "session": "ollie", "city": ""}]}
+```
+
+Exactly one binding per agent (singleton); `city` empty or absent means
+the adapter's own city, mirroring room bindings. Imported and inspected
+through the same `slack_company_directory.py` city-scoped
+import/inspect path that owns `company_bindings.json`, extended with a
+dm-bindings input (room bindings have no separate "import flow" —
+dm_bindings ride the identical read-validate-write mechanism and
+`(session, city)` guard).
+
+Rationale (corrected per review): the fabric's
+`ConversationRef{Kind: dm}` remains the right long-term home. What
+blocks adoption NOW is not the DedupKey gate itself (that gates the
+inbound *delivery* migration) but the split it would create: fabric-owned
+binding state with pack-owned wake delivery over
+`session/{id}/messages` gives two systems with different restart and
+ownership semantics for one conversation, and the fabric's Phase-1
+single-writer rule means the pack could not reconcile that split
+unilaterally. Phase 5 migrates bindings AND delivery to the
+fabric/ledger together, when DedupKey consumption is real. Revisit
+marker: `PHASE5-DM-FABRIC` at the binding-registry seam.
+
+### D-DM2: Allowed-human policy = workspace humans, optional allowlist
+
+A DM author is allowed when the author classifier (shared with rooms)
+returns `human` and the event's `team_id` matches the bound workspace.
+Allowlist semantics (fail-closed, corrected per review): if the
+directory document carries a top-level `dm_allowed_humans` key AT ALL —
+including an empty array — the allowlist governs: only listed Slack
+user IDs are allowed, and an empty list allows nobody. If the key is
+absent, all workspace humans are allowed. Denied authors' events are
+admitted and terminally resolved `dm_author_not_allowed` (visible in
+receipts; policy denials must not be silent drops). Directory-wide,
+not per-agent, in v0.
+
+## Wire and manifest changes
+
+`manifest/agent-app.json` template delta (single update, one reinstall):
+
+- `oauth_config.scopes.bot`: add `im:history` AND `reactions:write`
+  (the DM ack actor is the agent app — see Acks; rooms' ack actor is
+  the switchboard, which already has it).
+- `settings.event_subscriptions`: `request_url` (same public funnel
+  endpoint as the switchboard) + `bot_events: ["message.im"]`.
+- Messages tab settings already correct from Phase 2a.
+
+Scope additions require per-app reinstall. **Delayed Events must be
+enabled on every agent app** (18 apps + explicitly in the pilot step) —
+the degraded-mode recovery below depends on Slack's redelivery horizon
+exactly as rooms do; without it the 503-redrive model silently loses
+DMs after the ~immediate/+1m/+5m retry ladder. Switchboard manifest:
+unchanged.
+
+## App registry and app-bound signature verification
+
+### Registry: new Phase 4 work, not reuse
+
+The existing `import-app` flow and `apps.json` records have NO
+`agent`, `bot_user_id`, or `signing_secret` fields, and import-app's
+manifest validation would reject agent-app manifests — the v1 spec was
+wrong to claim otherwise. Phase 4 adds:
+
+- A new CLI verb `gc slack register-agent-app` (both CLI ports) writing
+  records `{team_id, api_app_id, signing_secret}` into a NEW
+  `agent_apps.json` registry (schema_version'd, 0600, loaded at startup
+  and on SIGHUP like the other read-only registries). It does not touch
+  the legacy `apps.json` or import-app's validation profile.
+- Owner-agent identity is NOT stored there: it derives by joining the
+  envelope's `api_app_id` against `company_directory.json`
+  `agents[].app_id` (the directory already binds
+  name↔app_id↔bot_user_id and is the canonical identity source). A
+  registered secret whose api_app_id has no directory agent is a
+  startup/reload warning and admits nothing.
+- The switchboard's own identity needs no record: the adapter already
+  has `SLACK_APP_ID` and `SLACK_SIGNING_SECRET` in env; event_callbacks
+  claiming `api_app_id == SLACK_APP_ID` verify against the env secret
+  (the true "existing path, unchanged").
+
+### Verification order (event POSTs)
+
+1. `type == "url_verification"`: no `api_app_id` in the handshake;
+   trial-HMAC across env secret + all registered agent secrets; echo
+   challenge on any match. Side-effect-free, so trial is acceptable
+   here and ONLY here.
+2. `type == "event_callback"`, `api_app_id == SLACK_APP_ID`: verify
+   against env secret only (rooms path, unchanged).
+3. `type == "event_callback"`, `api_app_id` has a registered agent
+   record: verify against exactly that record's secret. Mismatch →
+   HTTP 401, counter `company_dm_sig_reject`. A signature that matches
+   a DIFFERENT registered app's secret is still 401 (rule 12 spoof) —
+   the bind check is authoritative, no fallback.
+4. `type == "event_callback"`, unknown `api_app_id`: legacy trial-HMAC
+   fallback (parent's carve-out for legacy single-app installs,
+   restored per review) — but a trial match against a REGISTERED agent
+   secret is rejected, not accepted: registration opts an app into
+   strict binding permanently.
+
+Timestamp-skew rules unchanged.
+
+## Admission
+
+DM events: `event_callback` with inner `channel_type == "im"` from a
+registered agent app (verification rule 3).
+
+Gate:
+1. Signature bound to the delivering app (above), and the app joins to
+   a directory agent.
+2. `channel_type == "im"`; subtype allowlist IDENTICAL to rooms'
+   `AdmissibleSubtype` set in `company_routing.go` (no separate DM
+   table; the v1 "edit/delete shapes" language was wrong).
+3. ALL admissible DM events are admitted — human AND bot-authored.
+   In a 1:1 `im` the only possible bot author is the owner app itself
+   (self-echo of its own outbound posts). Self-echoes admit with an
+   immediately-terminal status `no_delivery / dm_self_echo`, routed to
+   nobody. This keeps the receipt store the dedup memory AND the
+   reconciliation source for DM outbound posts — the reconciler is
+   receipt-scan-only by design (`_scan_receipt_for_nonce` never calls
+   the Slack API), and rooms only work because bot echoes become
+   receipts; the v1 no-receipt rule would have wedged every timed-out
+   DM reply permanently (review blocker C2/C9).
+
+Receipt key `(team_id, dm_channel_id, ts)`, same store, plus
+`kind: "dm"` and `owner_app_id`. All Phase 1 admission mechanics apply
+verbatim (O_EXCL claim-and-content, dedup-before-200,
+503-without-`x-slack-no-retry`, redelivery absorption, company-scoped
+startup barrier, 7-day retention).
+
+Degraded mode: same 503 rule per app. Auto-disable budgets are per
+agent app; runbook: an adapter outage now risks 19 subscriptions, the
+re-enable step is per app, and messages sent during a disable window
+were never admitted — humans re-send; there is NO history backfill on
+re-enable in v0 (explicitly out of scope).
+
+## Routing
+
+For an admitted DM receipt:
+
+- Owner agent = directory agent joined from `owner_app_id`. Exactly one
+  admission owner per DM (the app only receives its own `message.im`).
+- Self-echo → terminal `dm_self_echo` (above), nobody woken.
+- Allowed human → single target `dm_bindings[agent]`, wake kind `dm`.
+  No mention semantics, no ambient set, no delegation authority (the
+  human-root gate refuses delegation verbs from a `dm`-kind root).
+- Not-allowed author → terminal `dm_author_not_allowed`.
+- Unbound agent (no dm_bindings row) → the ROOMS rule, not a park
+  (v1's park diverged from precedent): a recorded FAILED target
+  (`failed_dm_unbound`, definitive), recoverable via the existing
+  `company-redrive` re-resolution machinery after a binding is
+  imported. No retention exemption, no unbounded accumulation, and the
+  operator drains it with the tool built for exactly this in Phase 3.
+- Delivery reuses `TargetDelivery` verbatim (city-qualified resolution,
+  idempotency keys, sweep, claims, generation counters).
+
+## Session-existence guard (shared hardening, revised)
+
+`SLACK_COMPANY_VERIFY_SESSIONS=1` (default off): before the first
+delivery attempt per `(city, session)`, GET
+`/v0/city/{city}/session/{session}`. Results are advisory, never
+terminal (v1 terminalized — wrong: today's fleet showed sessions
+404-then-materialize and aliases go 409-ambiguous transiently):
+
+- 200 → proceed; cache positive for 10 minutes.
+- 404/409 → leave the target PENDING with detail
+  `session_missing`/`session_ambiguous`; do NOT post; the 60s sweep
+  re-checks. Negative results are not cached. The existing
+  per-target attempt cap bounds the loop; targets that exhaust it fail
+  with the detail preserved and are company-redrive-recoverable.
+- Guard-check network errors → proceed as if unchecked (the guard must
+  never reduce availability below flag-off behavior).
+
+Applies to room and DM deliveries equally.
+
+## Owner-token custody in the Go gateway (new Phase 4 work)
+
+DM hydration, DM acks, and the DM failure-reply need the OWNER AGENT's
+bot token; the Go gateway today holds only the switchboard token,
+wired at construction into `hydrate`/`reactHook`/`replyHook`. Phase 4
+amends the Phase 2 ownership split: the Go adapter gains a per-agent
+token loader over the company secrets dir (`bot-token-<agent>.txt`,
+same refusals as the Python loader: file not 0600 → refuse, dir not
+0700 → refuse, symlink → refuse), selected per receipt: room receipts
+keep the switchboard token unconditionally; `kind: "dm"` receipts
+resolve owner agent → token. A DM receipt whose owner token is missing
+delivers with `context_unavailable` hydration and degraded acks
+(counter `company_dm_token_missing`) rather than trying the
+switchboard token, which must never be used on a DM channel. Config:
+the secrets dir is the existing `SLACK_COMPANY_SECRETS_DIR` (shared
+with the Python side).
+
+## Hydration, pointer, reply
+
+- Hydration: frozen-snapshot discipline as rooms, reading
+  `conversations.history` on the DM channel with the owner token
+  (`im:history`), same bounded window and `include_all_metadata`.
+- Current-turn pointer: DM turns get their OWN pointer file in a
+  dedicated subdirectory `company-current-turn/dm/<session>.json`
+  (created 0700 on demand) — a shared singleton would let a room wake
+  clobber a DM turn and misdirect a private reply into a room (review
+  C6). A flat `<session>.dm.json` would still collide with the room
+  pointer of a session literally named `<session>.dm` (the shared
+  sanitizer passes interior dots through), so the DM pointer is
+  namespaced under its own subdirectory rather than by suffix, keeping
+  the DM and room namespaces disjoint for every session name. Pointer
+  contract delta is explicit cross-language
+  work: add `"dm"` to `_TURN_KINDS` and the Go/Python kind sets; `room`
+  field empty and permitted-empty for kind `dm` (validator relaxation
+  in both languages); new `owner_app_id` field; golden + interop
+  fixtures for the DM pointer and `dm_bindings.json`.
+- `gc slack reply-current`: resolves the pointer by kind — with both a
+  room and a DM pointer live, the NEWEST by delivered-at wins, and
+  explicit `--kind room|dm` overrides; origin-ts pinning is honored as
+  today. Posting uses the owner token to the DM channel via the SAME
+  durable-intent machinery (create intent → CAS attempts →
+  Retry-After → receipt-scan reconciliation, which works because
+  self-echoes are admitted). Root derivation unchanged (`thread_ts`
+  else `ts`), but DM POSTING is flat: a reply whose root equals the
+  turn's own `ts` (a top-level DM message) posts in-channel with no
+  `thread_ts`; threading applies only when the human themselves
+  replied inside a thread. (Rooms thread to protect channel
+  timelines; a 1:1 DM has none, and a threaded reply hides behind a
+  thread indicator the human easily misses — observed live on the
+  first pilot DM.)
+- Spoof guard: extended, not reused — the room guard is keyed against
+  `company_bindings.json`; kind-`dm` replies validate through
+  `dm_bindings` (the session must be the one the DM pointer's owner
+  agent binds to), with the same dot/dunder session aliasing.
+- Visible acks (same config flag): ack actor in a DM is the owner
+  token (`reactions:write` added above). 👀 admission, ✅ delivered,
+  ⚠️ terminal-with-failures; AckState cursor and sweep-healing
+  unchanged. Missing owner token → acks silently degrade (counted).
+
+## Observability
+
+`/healthz` additions (v1 cited a surface it never defined):
+`company_dm_receipts` (by status), `company_dm_sig_reject`,
+`company_dm_token_missing`, `registered_agent_apps` (count +
+directory-join warnings). Existing stale-intent and park counters
+apply to DM receipts unchanged.
+
+## Out of scope (unchanged deferrals)
+
+Bot→bot DMs, DM-rooted delegation, `mpim` group DMs (not subscribed;
+`channel_type` gate), token rotation automation, history backfill
+after auto-disable, extmsg fabric adoption (`PHASE5-DM-FABRIC`).
+
+## Config summary
+
+| Item | Meaning |
+| --- | --- |
+| `dm_bindings.json` | agent → singleton (city, session); schema v1 |
+| `agent_apps.json` + `register-agent-app` | (team_id, api_app_id, signing_secret) |
+| `dm_allowed_humans` (directory, optional) | present ⇒ allowlist mode (empty = nobody) |
+| `SLACK_COMPANY_VERIFY_SESSIONS` | 0/1 advisory session-existence guard |
+| `SLACK_COMPANY_SECRETS_DIR` | now also read by the Go adapter (DM tokens) |
+
+## Test plan (maps to acceptance rule 12)
+
+1. App-bound HMAC: event claiming app A signed with app B's secret →
+   401, no receipt; unknown api_app_id + valid legacy secret → legacy
+   trial path admits (carve-out); unknown api_app_id + registered
+   agent secret → 401 (registration is strict).
+2. `url_verification`: any registered secret → challenge; none → 401.
+3. Human DM admitted once; redelivery (`x-slack-retry-num` ≥ 1) → 200,
+   no second receipt.
+4. Self-echo DM → admitted, terminal `dm_self_echo`, nobody woken; a
+   stuck posting intent reconciles against that receipt's nonce.
+5. `dm_allowed_humans` present+empty → every human terminal
+   `dm_author_not_allowed`; absent → workspace humans allowed.
+6. Unbound agent → `failed_dm_unbound` target; import binding +
+   company-redrive → delivered.
+7. DM pointer written to `company-current-turn/dm/<session>.json`;
+   concurrent room turn (including one for a session named `<x>.dm`)
+   does not clobber it; reply-current picks newest, `--kind` overrides;
+   owner-token post; unbound session reply → spoof-guard refusal.
+8. Delegation verb from a dm-kind root → refused.
+9. Guard on: 404 session → target stays pending, sweep retries,
+   attempt-cap exhaustion preserves detail; guard network error →
+   delivery proceeds.
+10. DM receipt-store write failure → 503 without `x-slack-no-retry`;
+    retry admits once.
+11. Missing owner token → delivery with `context_unavailable`,
+    degraded acks, counter increments; switchboard token never used
+    (assert no API call with it on the DM channel).
+12. Golden/interop fixtures: `dm_bindings.json`, DM pointer, captured
+    real `message.im` (wire-shape pin: envelope `api_app_id` presence,
+    exact `channel_type`, self-echo shape with metadata).
+
+## Operator runbook (delta, ordered)
+
+0. Deploy the Phase 4 adapter + CLI build FIRST (register-agent-app
+   and the verification order ship together; on manual installs the
+   switchboard path needs `SLACK_APP_ID` already in env — it is).
+1. Per agent app (pilot: OLLIE only, then the other 17): harvest the
+   signing secret from Basic Info → `gc slack register-agent-app` →
+   confirm `/healthz` `registered_agent_apps` increments with no
+   directory-join warning.
+2. Update the app manifest: `im:history` + `reactions:write` +
+   `message.im` event subscription with the shared funnel Request URL.
+   The handshake fires on save and verifies via the trial path —
+   registration MUST precede the Request URL, else 401.
+3. Reinstall the app to the workspace (scope change). Reinstall does
+   not rotate the signing secret; the bot token rotates only if
+   explicitly reissued — if it was, re-drop `bot-token-<agent>.txt`.
+4. Enable Delayed Events on the app.
+5. Import `dm_bindings.json` (start: ollie → its session), restart or
+   SIGHUP the adapter, DM the app as a human: 👀→reply→✅ in the DM.
+6. Replay + spoof fixtures against the live endpoint before rolling
+   the fleet.

+# Phase 4b — Group DMs (mpim): Implementation Spec (v2)
+
+Status: revised after adversarial review (18 confirmed findings, 5
+blockers; archive wf_7c0b3105-2ea), then clarified in the Phase 4b
+pre-commit review (provenance freeze + human-only downgrade + root-leg
+downgrade, missing-token probe block, owner-join-loss degrades ack only,
+vanished-agent pointer skip). Extends Phase 4
+(`phase4-dm-spec.md`); rule-12 analogues apply. Motivating
+requirement (2026-07-19): group DMs with agents woke nobody.
+
+DIVERGENCE NOTE for the ledger owners: the core Slack companion pins
+personas to `message.im` only; `message.mpim` is a deliberate
+pack-side extension (Slice-0 ask #7). SECURITY DELTA acknowledged: in
+1:1 DMs one compromised app secret exposes only that app's DMs; with
+mpim any registered agent secret can forge events for group channels
+— mitigated by the membership probe below.
+
+## Semantics
+
+- Wake policy: MENTION-ONLY. A human message natively mentioning
+  member agents wakes exactly the mentioned, homed agents (mention
+  extraction identical to rooms). Unmentioned human messages →
+  terminal `no_delivery / mpim_no_mention`. Bot-authored → terminal
+  `no_delivery / mpim_bot_author` (reconciliation memory). No
+  ambient set exists. No delegation from mpim roots.
+- The directory is NOT extended: no mpim rosters; dm_bindings is the
+  only wake registry.
+- `dm_allowed_humans` (when present): a non-allowed ROOT author →
+  terminal `dm_author_not_allowed` exactly as dm. Additionally,
+  because group hydration can excerpt non-allowed members' text, the
+  reminder's provenance line downgrades to `human_root_unlisted`
+  (never "verified") whenever any unlisted HUMAN author appears in the
+  frozen hydration — either the verified thread-root author or any
+  excerpt line. Only humans participate: an excerpt line authored by a
+  directory agent (its `bot_user_id`) or a classic bot (empty user id)
+  is NOT an "unlisted human" and never downgrades, so an agent's own
+  reply in the recent window cannot poison the signal. The verdict is
+  computed ONCE when the hydration snapshot freezes and persisted in
+  the blob, so every retry renders byte-identical reminder bytes (the
+  frozen-hydration discipline — never recomputed from the live
+  directory). Agents are instructed to treat unlisted-author content
+  as untrusted context. Data-at-rest note: mpim admission makes
+  human-to-human group text a durable receipt-store class for the
+  7-day retention window; the Phase 5 body-store split is the
+  redaction point and its admin verb applies.
+
+## Admission
+
+- Each member agent app subscribes to `message.mpim` (scope
+  `mpim:history`).
+- Admission accepts `channel_type == "mpim"` from a REGISTERED agent
+  app (verification order unchanged). The switchboard ALREADY
+  subscribes to `message.mpim` (existing manifest): switchboard-signed
+  mpim events are acked 200 with NO receipt and NO legacy dispatch —
+  they must not double-deliver nor fall through (the switchboard has
+  no business in agent group DMs; documented, not manifest-changed).
+- Origin key `(team_id, mpim_channel_id, ts)` dedups multi-app
+  observation: the first member app's event admits; the rest absorb
+  as replays. Receipt kind `mpim`; receipt-level `owner_app_id` =
+  admission winner = ACK ACTOR ONLY (never a wake-target input). If the
+  winner's directory join is lost after admission (offboarded mid-
+  flight), that ONLY degrades the visible ack (counted, like a missing
+  owner token); it never parks the receipt — the other mentioned
+  agents' targets are independent of the owner and must still wake.
+  Delivery parks only when routing itself cannot proceed (a registry-
+  unavailable author answer, or a wholly empty/unavailable directory
+  snapshot that cannot resolve any mention).
+- Self-echo N-plication is absorbed the same way; first copy admits
+  as `mpim_bot_author`.
+- Membership probe (blast-radius mitigation): before the FIRST
+  delivery attempt for each woken agent, the delivery worker probes
+  the mpim with that agent's own token (`conversations.info`);
+  `not_in_channel`/`channel_not_found` → recorded failed target
+  `failed_mpim_not_member` (redrive-recoverable), never a wake. A
+  MISSING/unloadable woken-agent token also BLOCKS the wake as
+  `failed_mpim_not_member` (durable local state, not a transient error —
+  redrive-recoverable once the token is dropped): advisory-proceed is
+  reserved ONLY for genuine probe transport errors (network / non-
+  membership Slack errors), like the session guard.
+
+## Kind-dispatch inventory (normative — review C4/C10)
+
+A shared predicate `isDMFamilyKind(kind)` covers `dm` and `mpim`.
+Every existing `Kind == "dm"` seam changes as follows:
+
+| Seam | mpim behavior |
+| --- | --- |
+| `deliverReceipt` dispatch | dm-family → the DM worker (extended, below); never the room path (an mpim receipt in the room path parks forever on `RoomByChannel`) |
+| `ackActorToken` / `noteDMAckDegraded` | dm-family: owner-app join → owner token; degradation counters shared |
+| `applyRedrive` unbound re-resolution | dm-family: re-resolve via dm_bindings by agent (extends the dm-only gate) |
+| receipt status gauges | dm-family folded into the existing single-scan tally, reported as `company_dm_receipts` plus a `company_mpim_receipts` breakdown |
+| `writeCurrentTurnPointer` subdir | kind dm → `dm/`; kind mpim → `mpim/` (NEW subdirectory, 0700 on demand) |
+| pointer validators (both languages) | `"mpim"` added to kind sets; `room` empty-permitted; `owner_app_id` REQUIRED non-empty (see Pointer) |
+| delegation human-root gate | dm-family refused |
+| session-existence guard | dm-family and rooms alike (unchanged) |
+
+## Routing and delivery (corrected seam — review C2/C13)
+
+mpim extends the DM DELIVERY WORKER (`deliverDMReceipt`/
+`deliverDMTargets`), which is already multi-target-capable via the
+per-receipt `TargetDelivery` map:
+
+1. Author policy (dm rules) → terminal reasons above when no wake.
+2. Mention set = `ExtractMentionIDs` × directory `bot_user_id`s (no
+   room membership/eligibility analog — Slack membership is the
+   roster, enforced by the probe).
+3. Route freeze: one target per mentioned agent via
+   `dm_bindings.BindingFor(agent)`; unhomed → `failed_dm_unbound`
+   (redrive-recoverable via the extended gate).
+4. Per-target delivery loop, idempotency keys, sweep, generation
+   counters, `computeReceiptStatus` — reused verbatim from the DM
+   worker.
+5. Reminder: a dedicated mpim renderer (group framing, member
+   context, provenance line per the allowlist rule).
+
+## Hydration (pinned — review C5/C14)
+
+ONE frozen hydration blob per receipt (content is token-independent:
+same channel history). Token choice: the ADMISSION OWNER's token
+first; on missing token file, deterministic fallback over the woken
+agents' tokens (sorted by agent name); degrade to
+`context_unavailable` only when none load. Replies still use each
+woken agent's OWN token.
+
+## Pointer and reply (corrected — review C1/C3/C6/C8/C11/C12)
+
+- mpim turns get their OWN pointer namespace:
+  `company-current-turn/mpim/<session>.json`. All three kinds are
+  distinct live files; `resolve_reply_pointer_source` becomes
+  three-way newest-wins; `--kind` accepts `room|dm|mpim`. (A shared
+  dm/ file would be last-writer-DESTROYS: an mpim wake would
+  irrecoverably clobber an unanswered 1:1 DM turn — the exact
+  C6-class misdirection Phase 4's subdirectory exists to prevent.)
+- Pointer `owner_app_id` for kind mpim = the WOKEN AGENT's own
+  directory app_id (per-target pointer, per-session file — matches
+  the dm validator's owner-join check so every woken agent's reply
+  passes its own guard). The RECEIPT-level owner_app_id (admission
+  winner / ack actor) is a different field with different semantics;
+  the spec's tests pin both. If the woken agent vanished from the
+  directory between route-freeze and the pointer write, its app_id
+  resolves empty — the worker MUST NOT write that pointer (an empty
+  `owner_app_id` is refused at parse time and would brick reply-current
+  for EVERY kind on that session, including its live room/dm turns). It
+  instead fails the target recoverably (`failed_mpim_agent_unknown`,
+  redrive-recoverable) with no pointer and no wake. Defense in depth:
+  `resolve_reply_pointer_source` treats a pointer that fails parsing as
+  absent for auto-resolution (so one corrupt file cannot disable the
+  session's other reply surfaces), raising only when that kind is the
+  explicit `--kind`.
+- Reply: the woken agent's token, flat unless the human threaded
+  (Phase 4 rule), through the durable-intent machinery with intent
+  op `dm` (unchanged — reconciliation matches the admitted
+  `mpim_bot_author` echo receipts by nonce exactly as dm; a distinct
+  op would break `_scan_receipt_for_nonce`'s gates).
+- Spoof guard: kind-mpim replies validate through dm_bindings for
+  the pointer's agent, same aliasing.
+
+## Out of scope
+
+Ambient in mpim (by design), agent-initiated mpim creation, mpim in
+the directory, switchboard manifest changes, the ledger companion's
+stance (ask #7).
+
+## Config
+
+None new.
+
+## Test plan
+
+1. Mention ollie only → exactly ollie wakes; olivia (member,
+   unmentioned) does not.
+2. Mention both → two targets on one receipt, both deliver via the
+   DM worker; one unhomed → failed_dm_unbound; `company-redrive`
+   after binding import delivers it (redrive gate extension pinned).
+3. Unmentioned human → terminal mpim_no_mention; bot-authored →
+   terminal mpim_bot_author; both recorded, nobody woken.
+4. Multi-app duplicate admission → one receipt; ack actor = winner;
+   switchboard-signed mpim copy → 200, no receipt, no legacy
+   dispatch.
+5. Pointer isolation: dm turn then mpim turn for the same session →
+   BOTH live; newest wins; `--kind dm` recovers the older 1:1 turn;
+   each pointer's owner_app_id = that turn's woken agent.
+6. Reply: each woken agent posts flat with its own token; the
+   non-winner agent's reply passes the guard (C11 regression); a
+   session not bound to the pointer agent is refused.
+7. Membership probe: forged event for a group the agent is not in →
+   failed_mpim_not_member, no wake; probe network error → delivery
+   proceeds.
+8. Allowlist: non-allowed root author → dm_author_not_allowed;
+   allowed author + unlisted excerpted member → reminder provenance
+   `human_root_unlisted`.
+9. Replay/spoof: retry-num absorbed; cross-app signature 401 (rule
+   12); hydration token fallback order; ack degradation counters.
+10. Wire fixture: captured real `message.mpim` event (envelope
+    api_app_id, channel_type, mention rich_text synthesis in mpim —
+    MUST be captured live before the mention extractor is trusted,
+    since rich_text synthesis is only pinned for channels).
+11. Delegation from mpim root → refused.
+
+## Rollout (ordered — review C17)
+
+0. Implement + deploy the adapter's mpim branch FIRST. Interim
+   truth: until deployed, member-app `message.mpim` events fall into
+   the LEGACY dispatch path N-plicated (once per member app) — the
+   bulk manifest update MUST NOT precede the adapter deploy.
+1. Capture the live mpim wire fixture (one app, one test group).
+2. Bulk manifest update via the config token: add `mpim:history` +
+   `message.mpim` to all 18 agent apps; reinstalls activate the
+   scope.
+3. Pilot: the user's existing group DM (ollie + olivia): mention
+   each in turn (exclusive wakes), both (two targets), unmentioned
+   message (no wake), reply guard for the non-winner.
+4. Fleet-wide.

+# Phase 5 — Ledger Integration: Readiness Assessment and Scoped Increment
+
+Status: ACTIVE. Written 2026-07-19 against the uncommitted
+durable-request-ledger v0 drafts (`engdocs/proposals/` in the core
+checkout at `/data/projects/gascity-durable-request-ledger`, branch
+`design/durable-request-ledger-v0`) and their Slack companion docs.
+Full contract digest archived with the migration artifacts
+(ledger-v0-contract-digest, 2026-07-19). Both drafts are `Proposed`;
+their Slice 0 reserves re-pinning of state and error vocabularies.
+
+## Gate ledger — what blocks what
+
+| Gate | State (2026-07-19) | Blocks |
+| --- | --- | --- |
+| Ledger v0 implementation | Design drafts only; zero code | Any live integration |
+| Slice 0 vocabulary pin | Not run | Pinning state/error names in code |
+| Slice 20 OpenAPI | Not generated | Writing ANY request/response DTOs — field spellings do not exist yet; generate the client from that artifact, never hand-write |
+| Beads create-only + CAS (upstream #4682) | Not landed | End-to-end activation |
+| Core multi-target delivery rework (Slack plan Task 1.2) | Unimplemented | Room (multi-wake) activation; the delivery read model will move |
+| extmsg `DedupKey` consumer in core | Still a no-op (types.go only) | Migrating wakes to `extmsg/inbound` (pre-existing Phase 5 gate, unchanged) |
+| Slack projector wake mechanism | UNSPECIFIED (UDS callback contract is Discord/Cherry-specific) | Outbound projector client design |
+
+Consequence: this phase ships NO wire client and NO mock server yet.
+The one implementable increment is the body-store split (below), which
+every draft revision pins invariantly.
+
+## Conformance: our shipped pack vs the Slack companion's adapter obligations
+
+The companion is a core-side thin-transport redesign, not a port of
+this pack — but its adapter-side obligations are largely what Phases
+1–4 already built:
+
+| Companion obligation | Our pack | Verdict |
+| --- | --- | --- |
+| 2xx to Slack only after durable spool row | Receipt O_EXCL claim-and-content before HTTP 200 | CONFORMANT |
+| One shared city-owned gateway; no per-app forwarders | Single adapter; per-agent apps are identity+DM-subscription only | CONFORMANT |
+| Personas subscribe `message.im` only; switchboard `message.channels`/`groups` | Exactly our Phase 2a/4 manifest split | CONFORMANT |
+| Native mentions exclusive, suppress ambient | Phase 1 routing table | CONFORMANT |
+| DM target fixed by verified `api_app_id`; in-DM mentions cannot fan out | Phase 4 app-bound HMAC + owner-app routing | CONFORMANT |
+| Durable outbound intent before every non-idempotent post | Phase 2 intents/outbox, receipt-scan reconciliation | CONFORMANT |
+| `event_id` must not be receipt origin | Our origin is `(team_id, channel_id, ts)` | CONFORMANT |
+| Transport-event dedup key `(workspace_id, api_app_id, event_id)` | We dedup by origin key only; no event_id inbox row | DIVERGENT (minor): adopt at client build time; our origin dedup subsumes redelivery in practice |
+| Receipts never carry raw bodies | Receipts EMBED the inner event today | GAP → closed by this increment |
+| Raw payload retained only until `core_bound`, then redacted | No redaction fence exists | PREPARED by this increment (fence hook; activation with the ledger) |
+| OpenBao-only credential access | File custody (pilot posture); vault convergence in progress with infra | DEFERRED (org-manifest phase, unchanged) |
+
+## Corrected state mapping (supersedes the plan's three-state note)
+
+The plan's `received→spooled`, `routing→admitting`, `terminal→terminal`
+is too coarse and names a state (`terminal`) the drafts do not have.
+The adapter journal must carry at least the Slack companion's six:
+`spooled`, `admitting`, `core_bound`, `body_redacted`, `rejected`,
+`quarantined` — with `core_bound` as the load-bearing fence: only
+after the qualified core receipt reference + digest are durable may
+the raw payload be redacted. Local mapping at client build time:
+
+| Local (Phases 1–4) | Ledger-mode journal |
+| --- | --- |
+| receipt created (pre-route) | `spooled` |
+| routing | `admitting` |
+| delivered/no_delivery/failed + core ref durable | `core_bound` → `body_redacted` |
+| signature/policy rejection | `rejected` |
+| same-key different-digest replay | `quarantined` |
+
+## Increment shipped this phase: body-store split
+
+Motivation (invariant across every draft revision): receipts must not
+carry raw bodies; the payload lives beside the spool and is
+redactable independently. Also standalone value: smaller receipts,
+cheaper scans, a single redaction point for retention.
+
+- New `bodies/` sidecar under the ingress store: one file per receipt
+  (`<receipt_id>.body.json`, 0600), holding the raw inner event
+  exactly as previously embedded. Created atomically BEFORE the
+  receipt in the admission sequence. A body without a receipt is
+  garbage collected by the janitor — but ONLY on affirmative receipt
+  absence (the receipt path and any quarantine sibling are lstat'd
+  before removal), never for a receipt merely unreadable this pass,
+  and never within a grace window (an in-flight cross-process
+  admission must be able to finish linking its receipt). Orphan
+  adoption is digest-checked: a divergent crash-orphan body (no
+  receipt claims it yet) is replaced with the admitted bytes rather
+  than birthing a permanent digest mismatch; first-writer-wins holds
+  whenever a valid receipt already owns the body. A receipt whose
+  body is missing or digest-mismatched is a recoverable integrity
+  error: delivery PARKS it (non-terminal, sweep-retried, counted on
+  /healthz) so an orphan-adoption repair or operator action can
+  restore it — it is never terminalized under a routing reason. A
+  corrupt receipt quarantined during a scan takes its intact body
+  aside with it (`<id>.body-<token>.corrupt`), preserving the payload
+  for forensics (the split-store analogue of the pre-split embedded
+  copy).
+- Receipt `event` field becomes a reference: `body_ref` (receipt id)
+  + the immutable `event_digest` (sha256 of the stored bytes) for
+  integrity. A `schema_version` bump on receipts; the reader accepts
+  BOTH shapes forever (old embedded receipts remain valid until
+  retention ages them out — no migration rewrite of live receipts).
+- All readers go through one accessor per language (Go
+  `receiptBody(rec)`, Python `receipt_body(rec)`): routing snapshot
+  building, hydration reminder rendering, reconciliation
+  (`_scan_receipt_for_nonce` — reads text/metadata through the
+  accessor), admin/redrive display. The accessor is the ONLY place the
+  body digest is verified; the periodic sweep classifies bodies by
+  existence and a bounded tombstone probe only (no per-body SHA under
+  the store mutex the admission hot path contends for), and a
+  read-path counter (`company_body_digest_mismatch`) keeps digest
+  integrity observable.
+- Every root-keyed derivation (the dgser serialization lock name, the
+  replay-chain root, the rendered `thread_root_ts`, the failure-reply
+  root) reads a `thread_root_ts` frozen onto the receipt at admission,
+  so a redacted or lost body can no longer collapse a threaded
+  receipt's root to its origin ts and diverge a redrive's lock name or
+  rendered root from the pre-redaction value. Legacy receipts fall
+  back to body-derivation.
+- Redaction hook: `redactReceiptBody(receiptID)` truncates the body
+  file to a fixed tombstone `{"redacted": true, "event_digest": ...}`
+  — NOT wired to any trigger in this phase (the trigger is the
+  future `core_bound` fence); exposed as an operator admin verb for
+  manual use only. It refuses (409) a non-terminal receipt and a
+  receipt younger than the outbound reconciliation horizon
+  (`INTENT_TTL_SECONDS`, so a stuck posting intent can still reconcile
+  against the body nonce), re-verifies the receipt still exists under
+  the store mutex (a swept receipt → 404, never a resurrected
+  tombstone), and redacted receipts stay visible in root-filtered
+  admin listings with a `body_state` marker rather than silently
+  dropping out.
+- Retention: body files delete with their receipt (janitor pairs
+  them); the digest survives in the receipt for late-redelivery
+  dedup semantics exactly as today.
+
+Out of scope (explicitly): wire client, mock server, DTOs, projector
+client, extmsg-inbound migration, event_id inbox rows, OpenBao
+credential resolution.

+
+1. Specify the Slack projector wake mechanism (same
+   `gc.request-ledger.projector-callback.v1` UDS contract, or an
+   HTTP/funnel variant) — riskiest unspecified seam for us.
+2. Expose per-target delivery state to adapters (the
+   `request-delivery` records are HTTP-invisible; multi-target rooms
+   need at least a read model for redrive tooling parity).
+3. Reconcile the companion's `triage=not_applicable` and `WakeReason`
+   vocabulary with the neutral design's axes before Slice 0 pins.
+4. Confirm no If-Match protocol is intended (ETag response-only) so
+   our client design does not assume preconditions.
+5. Publish the Slice 20 OpenAPI artifact to a stable path we can
+   vendor as the DTO source.
+6. Our shipped pack already satisfies the companion's adapter
+   obligations except the two rows marked above — the companion can
+   cite this pack as its reference adapter rather than respecify.

+## Agent identity apps
+
+`agent-app.json` is the manifest template for a **company-rooms agent
+identity app** — one minimal Slack app per named directory agent (see
+`docs/company-rooms.md`). Its bot user is the agent's real, mentionable
+`<@U…>` identity in company rooms, and its bot token is the agent's
+outbound sending identity for `gc slack delegate` / `reply-current`.
+It is deliberately minimal: bot user, App Home Messages tab enabled,
+interactivity/Socket Mode/token rotation off. For **room** traffic the
+switchboard (`app.json`) stays the single admission owner — the agent app
+observes no room events.
+
+The **per-agent DM phase (Phase 4)** turns each agent app into the
+admission owner of its own DMs. The template now declares:
+
+- `oauth_config.scopes.bot`: `chat:write`, **`im:history`** (read the DM
+  channel for hydration), and **`reactions:write`** (the agent app is the
+  visible-ack actor on its own DM channel — the switchboard token is never
+  used on a DM channel).
+- `settings.event_subscriptions.bot_events`: **`message.im`**, pointed at
+  the **same public funnel `request_url` as the switchboard**. As with
+  `app.json`, the committed template omits `request_url` (it is
+  deployment-specific); add
+  `"request_url": "https://<your-funnel-host>/slack/events"` inside the
+  `event_subscriptions` block before pasting/updating.
+
+Scope + event changes require a per-app **reinstall** (18 apps + the pilot
+step). **Delayed Events must be enabled on every agent app** — the
+degraded-mode 503-redrive recovery depends on Slack's redelivery horizon
+exactly as rooms do.
+
+The template ships two `REPLACE-agent-name` placeholders
+(`display_information.name` and `features.bot_user.display_name`).
+Replace both with the agent's directory slug before creating each app.
+
+> **Never distribute an agent identity app on the Slack Marketplace.**
+> These are internal to one visibility boundary; public distribution
+> demotes `conversations.*` into a stricter rate tier.
+
+### Per agent
+
+1. **Create + install.** Copy `agent-app.json`, substitute both
+   `REPLACE-agent-name` placeholders with the agent slug, then
+   <https://api.slack.com/apps> → **Create New App** → **From an app
+   manifest** → pick the workspace → paste the edited JSON → **Create**
+   → **Install to Workspace** to mint the bot token (`xoxb-…`).
+2. **Harvest identifiers into the directory TOML.** Grab the **app id**
+   (`A0…`, Basic Information) and the **bot user id** (`U0…` — run
+   `auth.test` with this app's `xoxb-…` token; its `user_id` is the bot
+   user id). Write both into the agent's `[[agents]]` entry in the
+   company-directory TOML (`name` / `app_id` / `bot_user_id`), then
+   `gc slack import-company-directory --file <rooms.toml>`.
+3. **Register the signing secret, THEN wire the Request URL (order
+   matters).** Harvest the app's signing secret (Basic Information → App
+   Credentials → Signing Secret) and register it:
+
+   ```bash
+   gc slack register-agent-app --team-id <T…> --api-app-id <A…> --signing-secret <secret>
+   ```
+
+   This writes a `{team_id, api_app_id, signing_secret}` record into
+   `agent_apps.json` (a NEW registry, 0600, loaded at startup and on
+   SIGHUP — distinct from `apps.json`). Confirm `/healthz`
+   `registered_agent_apps` incremented **with no join warning**
+   (`registered_agent_apps_join_warnings=0`) — a warning means the
+   `api_app_id` has no matching `agents[].app_id` in the directory, and
+   the app will admit nothing until you fix the directory. Only **after**
+   registration, set the `message.im` Request URL in the manifest and
+   save: the verification handshake fires on save and verifies via the
+   trial path, so **registration MUST precede the Request URL, else the
+   handshake 401s.**
+4. **Drop the bot token into the company secrets dir.** Write the
+   `xoxb-…` token to `secrets/bot-token-<agent>.txt` under the adapter
+   state root (`SLACK_COMPANY_SECRETS_DIR`, else
+   `<GC_CITY_PATH>/.gc/slack/secrets/`). The token loader **refuses**
+   any file that is not mode `0600`, whose directory is not `0700`, or
+   that is a symlink — this is validation, not trust, so set the modes
+   when you write the file:
+
+   ```bash
+   install -d -m 0700 "$SLACK_COMPANY_SECRETS_DIR"
+   install -m 0600 /dev/null "$SLACK_COMPANY_SECRETS_DIR/bot-token-<agent>.txt"
+   printf '%s' "$AGENT_BOT_TOKEN" > "$SLACK_COMPANY_SECRETS_DIR/bot-token-<agent>.txt"
+   ```
+5. **Invite the bot to its rooms.** In each directory room the agent is
+   a member of, `/invite @<agent>`. A member bot that has not joined a
+   room can neither be delivered its events nor post into it (private
+   rooms always require membership; this design never uses
+   `chat:write.public`, so public rooms behave identically).
+6. **Reinstall, enable Delayed Events, then bind a DM session.**
+   Reinstall the app to the workspace to pick up the new scopes
+   (reinstall does **not** rotate the signing secret; the bot token
+   rotates only if you explicitly reissue it — if it did, re-drop
+   `bot-token-<agent>.txt`). Enable **Delayed Events** on the app. Then
+   bind a DM session and reload:
+
+   ```bash
+   gc slack bind-company-dm --agent ollie --session ollie   # per-agent singleton
+   kill -HUP <adapter-pid>                                   # or restart
+   ```
+
+   `bind-company-dm` writes/updates one `{agent, session[, city]}` row in
+   `dm_bindings.json` (singleton per agent; omit `--city` for the
+   adapter's own city). To unbind — including clearing a **stale row**
+   left by an agent rename so the redrive-recovery flow can rebind the
+   session — use `gc slack bind-company-dm --remove <agent>` (the agent
+   need not still be in the directory), then `kill -HUP <adapter-pid>`.
+
+   DM the app as a human: you should see 👀 → the session's reply → ✅ in
+   the DM. Pilot **OLLIE only**, prove replay + spoof against the live
+   endpoint, then roll the remaining 17.
+
+**Ordering recap (the whole fleet depends on it).** Deploy the Phase 4
+adapter + CLI first; then per app: `register-agent-app` → manifest
+Request URL → reinstall → Delayed Events → `dm_bindings` import → SIGHUP.
+`register-agent-app` must precede the Request URL (the save-time handshake
+verifies via the trial path), and the DM binding must precede live traffic
+(an unbound agent records a `failed_dm_unbound` target, drained later with
+`gc slack company-redrive`).
+
+**App Home Messages tab.** The template enables it
+(`app_home.messages_tab_enabled: true`,
+`messages_tab_read_only_enabled: false`): it is a hard Slack prerequisite
+for a human to DM a bot, so the per-agent DM phase is dead-on-arrival
+without it. Leave it on.
+
+### Group DMs (Phase 4b)
+
+The **group-DM phase** lets a human wake agents by mentioning them in a
+multi-party DM (mpim). Wake policy is **mention-only**: a human message
+that natively mentions member agents wakes exactly the mentioned, homed
+agents (via `dm_bindings`); an unmentioned or bot-authored message wakes
+nobody (terminal `mpim_no_mention` / `mpim_bot_author`). There is no
+ambient set and no delegation authority from an mpim root. The template
+adds:
+
+- `oauth_config.scopes.bot`: **`mpim:history`** (read the group-DM channel
+  for hydration and the membership probe).
+- `settings.event_subscriptions.bot_events`: **`message.mpim`**, pointed
+  at the same public funnel `request_url` as `message.im`.
+
+The switchboard already subscribes to `message.mpim`; the adapter absorbs
+switchboard-signed mpim events (200, no receipt, no legacy dispatch), so
+**no switchboard manifest change is needed.**
+
+**Rollout ordering — the adapter deploy MUST precede the manifest update
+(spec §Rollout).** Until the mpim-aware adapter is deployed, a member
+app's `message.mpim` event falls into the legacy dispatch path,
+N-plicated once per member app. So:
+
+0. **Deploy the adapter's mpim branch FIRST.** Do not add `mpim:history` /
+   `message.mpim` to any agent app before the adapter that owns mpim
+   admission is live.
+1. **Capture the live mpim wire fixture** (one app, one test group) so the
+   mention extractor is validated against real `message.mpim` rich_text
+   synthesis before the fleet trusts it (the committed fixture is marked
+   replaced with a LIVE capture 2026-07-19 — rich_text mention synthesis confirmed in mpim).
+2. **Bulk manifest update via the config token**: add `mpim:history` +
+   `message.mpim` to all 18 agent apps; each reinstall activates the
+   scope. (No new `register-agent-app` or `dm_bindings` step — mpim reuses
+   the per-agent registration and DM bindings from Phase 4.)
+3. **Pilot** the existing ollie + olivia group DM: mention each in turn
+   (exclusive wakes), both (two targets on one receipt), an unmentioned
+   message (no wake), and confirm the non-winner agent's reply passes its
+   own guard.
+4. **Fleet-wide.**
+
+An agent that is mentioned but not actually in the group records a
+`failed_mpim_not_member` target (the membership probe), and one that has
+no `dm_bindings` row records `failed_dm_unbound`; both drain later with
+`gc slack company-redrive` once the agent is invited / bound.
+
+### Switchboard changes for company rooms
+
+Enabling company rooms also touches the switchboard app (`app.json`),
+and both changes require operator follow-up:
+
+- **Scope additions require a reinstall.** `app.json` now declares
+  `channels:read`, `groups:read` (per-room membership checks) and
+  `users:read` (`bots.info` author resolution). These are read-only API
+  scopes with **no** paired event subscription, so they do not change
+  the switchboard's `bot_events`. Adding scopes to an installed app is
+  not live until you **reinstall** the switchboard app to the workspace
+  (re-mint the bot token afterward).
+- **Enable Delayed Events on the switchboard app.** This is a required
+  operator step, not optional: it extends Slack's event redelivery to
+  hourly retries for 24 hours, which is what makes a receipt-store
+  outage recoverable rather than lossy (see `docs/company-rooms.md` →
+  Durable Admission).
+

+"""Company-rooms operator verbs for the slack-full pack (company rooms 3c).
+
+Two receipt-native operator surfaces layered on the adapter's internal
+listener:
+
+  * ``gc slack company-status`` — one view of a wedged flow end to end:
+    Python-owned reads (delegation records grouped by synthesis group with
+    S10-normalized snapshots, plus stale ``posting`` intents) joined with the
+    adapter's receipt/park/target state (``GET /internal/company/receipts``).
+  * ``gc slack company-redrive`` — reset selected receipt targets (or a
+    target-less parked receipt) and re-trigger delivery
+    (``POST /internal/company/redrive``), reusing the recorded idempotency
+    keys — never reposting to Slack.
+
+The receipt store has exactly one writer (Go, generation-CAS), so these verbs
+are thin clients: they never rewrite receipts. The internal listener is a UDS
+(``GC_SERVICE_SOCKET``, primary in gc's proxy_process mode — ``LISTEN_INTERNAL``
+is ignored when it is set) or a loopback TCP address. A base-URL string cannot
+express the UDS case, so the client is a connection factory:
+:func:`internal_connection` returns an :class:`http.client.HTTPConnection`
+subclass that dials ``GC_SERVICE_SOCKET`` when set, else TCP to
+``LISTEN_INTERNAL`` (default ``127.0.0.1:8766``). ``GC_SERVICE_SOCKET`` wins.

+"""Company-directory CLI surface for the slack-full pack (company rooms 1e).
+
+Three subcommands back three `gc slack` verbs:
+
+  * ``import-company-directory --file <rooms.toml>`` — parse and validate
+    the non-secret company directory TOML, expand ``*`` wildcards, and
+    atomically write the normalized ``company_directory.json`` registry.
+  * ``bind-company-agent --room --agent --session`` — record the singleton
+    ``(room, agent) -> session`` binding in ``company_bindings.json``.
+  * ``peers [--room]`` — report rooms, members, wake policy, bindings, and
+    best-effort switchboard-membership warnings from the normalized JSON.
+
+Both registries resolve to the same directory the adapter's other registries
+live in (``<GC_CITY_PATH>/.gc/slack/`` when set, else
+``/tmp/gc-slack-adapter/``), with the ``SLACK_COMPANY_DIRECTORY_PATH`` and
+``SLACK_COMPANY_BINDINGS_PATH`` env overrides taking precedence — mirroring
+``adapter/main.go``'s per-registry override convention.
+
+The directory is versioned, non-secret data and never contains tokens.
+Membership verification (``conversations.info`` / ``conversations.members``)
+is strictly best-effort: a missing token, a missing scope, or a failed check
+produces warnings, never an import failure.

+"""Company-rooms outbound surface for the slack-full pack (company rooms 2b).
+
+Python owns company *outbound* (the Discord ownership split): posting
+intents, per-agent token files, ``chat.postMessage``, delegation-record
+creation, receipt-based lazy recovery, and pruning. Go owns ingress
+(author resolution, trust, result-claim/expiry transitions, the mutable
+current-turn pointer, and immutable by-reference turn records). Both sides
+share on-disk state under the adapter state root, serialized by the lock
+contract and validated fail-closed on both sides.
+
+This module is a library: the ``gc slack delegate`` verb
+(``cmd_delegate``/``cmd_cancel``) and ``reply-current``'s company-context
+path both call into it. Every filename/lock/nonce derivation here is a
+byte-for-byte match of ``adapter/company_sanitize.go`` — the golden
+fixtures in ``tests/fixtures/company/`` pin the two sides together.

+"""Register a per-agent Slack app's signing secret (company rooms Phase 4).
+
+Backs the ``gc slack register-agent-app`` verb. It writes a
+``{team_id, api_app_id, signing_secret}`` record into the ``agent_apps.json``
+registry (schema_version'd, mode 0600), the app-bound signature-verification
+store the adapter loads at startup and on SIGHUP.
+
+This registry is SECRET-bearing (each record carries a signing secret), so it
+lives apart from the non-secret ``company_directory.json`` /
+``company_bindings.json`` surface: the file is written 0600 in a 0700 dir and
+this verb refuses to overwrite an existing registry whose permissions have been
+loosened to group/world (a possible leak the operator must investigate first).
+
+Owner-agent identity is NOT stored here — it derives by joining the envelope's
+``api_app_id`` against ``company_directory.json`` ``agents[].app_id`` (the
+directory is the canonical name<->app_id<->bot_user_id source). Registering an
+``api_app_id`` with no directory agent is a warning, never a failure: the app
+opts into strict binding immediately, but it admits nothing until the directory
+lists it.

-You are bound to a Slack conversation.
+You are bound to a Slack conversation shared with humans and other agents.
+{{- if .TemplateName }}
+You were created from the **{{ .TemplateName }}** template. When someone
+mentions "{{ .TemplateName }}" (or @{{ .TemplateName }}), they are likely
+addressing you.
+{{- end }}
 
 ## How inbound arrives
 
-Gas City injects a system reminder into your prompt when a new
-message lands in the bound conversation:
-
-```
-<system-reminder>
-New message in shared conversation slack/<channel-id>:
+Gas City injects a system reminder into your prompt when a message is
+delivered to you. In a company room the reminder names the room, the
+author class, and your wake kind:
 
-- <actor> (<kind>): <text>
-</system-reminder>
-```
+- `ambient` — an ordinary human message in a room where you are an
+  ambient reader. Nobody was mentioned; you received it because the room
+  is configured that way.
+- `thread_ambient` — an untagged human follow-up in a thread where your
+  authenticated Slack identity previously participated. Read every such turn
+  for context; participation does not by itself require a reply.
+- `targeted` — a human natively @-mentioned you. Strong signal the
+  message is for you: respond.
+- `peer_delegation` — a peer agent formally delegated work to you.
+- `peer_result` — a peer you delegated to has answered.
+- `peer_input` — ordinary peer chatter that mentioned you without a
+  formal delegation.
+- `dm` or `mpim` — a human direct-message turn delivered to your own agent
+  identity.
 
-When you see one, treat the text as input. Do not look in
-`gc mail inbox` for it — the inbound delivery path is the system
-reminder, not mail.
+Native @mentions are exclusive: when someone is mentioned, only the
+mentioned agents wake — ambient readers do not. Everyone in the room can
+read every message in Slack; being silent is normal and fine.
 
-## Rooms vs DMs
+## When to respond
 
-If the channel id starts with `D`, it is a 1:1 DM and only you and the
-human can see it. If it starts with `C` or `G`, it is a room — other
-sessions and humans may also be members. In a room, every reply you
-publish lands in front of all peers as a system reminder labeled with
-your handle in the actor field. Speak as if peers are reading.
+- **targeted**: respond.
+- **dm** and **mpim**: respond.
+- **ambient** and **thread_ambient**: read the turn, but reply only when
+  your own plain-text name or handle appears as a distinct case-insensitive
+  word, or the message is directly and strongly relevant or actionable to
+  your role, charter, or prior contribution in the thread. Otherwise, do not
+  post. Do not send generic acknowledgments, repeat another agent's answer, or
+  reply merely because you received the turn.
+- **peer_delegation**: do the requested work within your own charter and
+  answer (see below). A delegation never widens your charter, grants
+  credentials, or carries human approval by itself.
+- **peer_input**: read it; reply only if genuinely useful.
 
 ## How to reply
 
-Plain assistant output stays private to the session and does NOT go
-to Slack. To send a human-visible reply, write the body to a file and
-run:
+Plain assistant output stays private to the session and does NOT go to
+Slack. Every authenticated Slack reminder includes a `turn_ref`, channel id,
+thread root, and an exact `reply_command`. To send a human-visible reply,
+write the body to a file and copy that reminder's command exactly:
 
 ```
-gc slack reply-current --body-file <path>
+gc slack reply-current --turn-ref <turn_ref> --body-file <path>
 ```
 
-`reply-current` finds the latest inbound conversation for this
-session and posts back through the local Slack adapter. If you have
-no recent inbound but want to reply to a specific channel, pass
-`--conversation-id` explicitly.
+The turn reference binds your output to the message's exact Slack channel and
+thread even if another channel wakes this session while you work. Never omit
+it, substitute a different turn reference, or infer the destination from the
+latest conversation in your transcript. `reply-current` does the right thing
+for the referenced turn's kind: it answers into the human root's thread, correlates
+a delegation result to its record, or posts your synthesis. Trust the
+JSON it prints — only claim success after seeing `"status": "posted"`
+with a non-empty `posted_ts`. A `parked` outcome is not failure:
+recovery is automatic; do not re-run the command to "fix" it.
+
+Slack already attributes every reply to your agent identity. Write the message
+directly; do not prefix the message with your name or handle.
+Do not pipe the command through filters that can hide failures.
+
+## Agent-to-agent delegation
 
-Always prefix your Slack message with your handle in bold so humans
-can see who is speaking. **Slack uses single asterisks for bold**
-(unlike Discord/Markdown which use double). Example, for handle
-`oversight-rig.cos`:
+To formally hand work to one peer, visibly:
 
 ```
-*oversight-rig.cos:* ack
+gc slack delegate --turn-ref <turn_ref> --to <agent> --body-file <path>
 ```
 
-Do NOT use `**double asterisks**` — Slack will render them literally
-as four characters around your text instead of bolding.
+Do not type a textual `@name` and assume it wakes anyone — text that
+merely looks like a mention never wakes a session. The command resolves
+the peer's registered Slack identity, posts a native mention into the
+human root's thread, and durably records the expected responder.
+
+Rules that are enforced, not advisory:
+
+- Delegate only from a human-rooted turn (`ambient`, `thread_ambient`, or
+  `targeted`). A
+  delegated turn may not redelegate (`peer_redelegation: forbidden` in
+  your reminder is literal); `peer_input` and `peer_result` turns
+  cannot delegate either.
+- One pending delegation per peer per thread: cancel a dead one with
+  `gc slack delegate --turn-ref <turn_ref> --cancel --to <agent>` before
+  re-delegating.
+- Issue ALL intended sibling delegations before waiting for results.
+  `synthesis_ready` only covers delegations that already existed when a
+  result was claimed; it cannot account for one you create later.
+
+On a `peer_delegation` turn: do the work, then run the exact
+`gc slack reply-current --turn-ref ...` command from that reminder. It
+posts your result mentioning only the delegator and correlates it
+to the delegation record.
+
+On a `peer_result` turn: read the synthesis block in your reminder.
+While `synthesis_ready: false`, wait — siblings are still pending (they
+are listed). Synthesize only after a result reports
+`synthesis_ready: true`; then the exact turn-bound `gc slack reply-current`
+command posts your synthesis to the verified human root without re-mentioning
+peers or ambient agents. Readiness means every materialized compatible
+delegation has a durably claimed Slack result — not that every local
+delivery succeeded. `--allow-partial` exists for deliberately partial
+synthesis; use it only when you have decided not to wait.
+
+## DMs
 
-Do not pipe `gc slack reply-current` through filters that hide
-failures. Trust the JSON it prints — only claim success after seeing
-a result with no error.
+If the conversation id starts with `D`, it is a 1:1 DM — only you and
+the human see it. Company delegation never happens in DMs; requests and
+results stay visible in the room.

-You are `{{ .AgentName }}`, a Gas City `graph.v2` role worker for template

-
-## Core Rule
-
-You work only the routed bead assigned to this live session. Do not use
-`bd mol current` to infer workflow position. Do not assume a parent bead or
-root bead describes your work. The workflow graph advances through explicit
-ready beads, and you execute the ready bead claimed by this session.
-
-## Startup Claim Protocol
-
-`gc hook --claim --json` is the only permitted discovery source for routed
-workflow work. Do not run broad `bd ready`, `bd list`, root-bead searches,
-metadata searches, mail inspection, session-log inspection, or repository
-context gathering to find a bead. Never work a bead id unless it came from the
-immediately preceding `gc hook --claim --json` result in this claim block.
-
-Your immediate first action must be to run the exact claim command below as a
-single Bash command. Do not rewrite it, compress it into an `&&` chain, or
-debug it if it returns no work. Do not run `gc prime`, load skills, inspect
-runtime state, read repository files, explain the codebase, or gather any
-other context until a bead has been claimed. If the command prints
-`NO_ROUTED_WORK` or `CONFIG_REJECTED`, it has already drain-acked; stop
-immediately and exit. If it prints `CLAIM_REJECTED`, the command is handling a
-claim race internally; wait for it to either claim a bead or drain on no work.

---json`; do not repair the assignment by hand or search for work outside that
-command. Execute exactly the claimed bead's description and result contract.
-Close it with the requested `gc.outcome` metadata. If the bead does not specify
-a failure contract, mark an unrecoverable failure with `gc.outcome=fail` and a
-concise `gc.failure_class`/reason before closing it.
-
-Never use a bare `bd close` for a bead that asks for close metadata. First set
-the requested metadata on the claimed bead, then close the same bead id:
-
-```bash
-bd update "$GC_BEAD_ID" \
-  --set-metadata 'gc.outcome=pass' \
-  --set-metadata 'example.key=example-value'
-bd close "$GC_BEAD_ID"
-```
-
-Finding review issues, missing tests, or required follow-up is usually the
-bead's output, not a task execution failure. When a review bead asks for
-`gc.outcome=pass` plus verdict metadata, set `gc.outcome=pass` even when the
-verdict is `iterate`, `changes_required`, or similar.
-
-If later terminal commands do not inherit shell variables, use the explicit
-`CLAIMED_BEAD_ID`, `CLAIMED_ROOT_BEAD_ID`, and
-`CLAIMED_CONTINUATION_GROUP` printed by the claim command. Never run `bd
-update` or `bd close` with an empty id.
-
-When updating or closing a bead, pass exactly one explicit claimed bead id.
-Quote every metadata assignment and close reason. Do not put freeform prose or
-bare words after the bead id; `bd` treats every extra positional argument as
-another issue id and may fuzzy-match unrelated beads. Use `bd close
-"$CLAIMED_BEAD_ID" --reason '...'` for close notes.
-
-## Continuation Group Protocol
-
-Important metadata:
-
-- `gc.root_bead_id` - workflow root for this bead
-- `gc.scope_id` - scope/body bead controlling teardown
-- `gc.continuation_group` - beads that prefer the same live session
-- `gc.scope_role=teardown` - cleanup/finalizer work; always execute when ready
-
-After closing a claimed bead, check for more routed work before draining unless
-the bead's result contract explicitly says the final action is to drain and
-exit. Continue by running the same `GC_CLAIM` block again. The block uses
-`gc hook --claim --json`; if it returns no work, it drain-acks and exits.
-
-If you must drain explicitly, run this as your final command and exit:
-
-```bash
-gc runtime drain-ack
-```
-
-When the bead you just closed had a `gc.continuation_group`, continue only for
-work in that same continuation group or same `gc.root_bead_id`; otherwise drain
-instead of hopping to unrelated workflow work. If the next ready bead is
-teardown work, run it even if earlier work failed.
-
-## Notes
-
-- `gc.kind=workflow` and `gc.kind=scope` are latch beads. You should not
-  receive them as normal work.
-- `gc.kind=check|fanout|scope-check|workflow-finalize` are handled by the
-  implicit `workflow-control` lane. Normal workers should not receive them.
-- Do not say "drained" without actually running `gc runtime drain-ack`.

+#
+# All five templates set `max_active_sessions = 1` and nothing else: no
+# min_active_sessions, no scale_check, no namepool. That configuration spawns
+# nothing. internal/agentutil/pool.go ScaleParamsFor takes Min from
+# EffectiveMinActiveSessions(), and internal/config/session_capacity.go returns
+# 0 for it when MinActiveSessions is nil. The cap is what HOLDS the singleton.
+#
+# Three places in one binary disagree about this shape:
+#   - cmd/gc/cmd_lint.go agentHasPoolControls returns true on
+#     `MaxActiveSessions != nil`, so it fires here.
+#   - internal/doctor/checks_named_session.go (check "named-always-min-conflict")
+#     warns only when EffectiveMinActiveSessions() > 0, so it is silent here.
+#   - internal/config/session_capacity.go SupportsInstanceExpansion documents
+#     "Named-session agents (MaxActiveSessions=1 with a [[named_session]] entry,
+#     no Min/ScaleCheck)" as a shape it deliberately handles.
+#
+# Following the remediation text would delete the cap that enforces the
+# singleton. The documented escape hatch (min=0 AND max=0) is worse: at max=0
+# SupportsGenericEphemeralSessions returns false, which changes how the agent

+# 2. `mol wisp` x2: the flag manifest stops one subcommand level short
+#
+# The template writes `gc bd mol wisp gc --age 24h`, which is correct. --age is
+# a flag on the `mol wisp gc` subcommand, shown in that subcommand's own --help
+# examples. internal/bdflags/bdflags.go keys its manifest on at most two words
+# ("mol wisp"), so matchSubcommand stops there, treats the third word `gc` as a
+# positional, and validates --age against the parent's flag set.
+#
+# The scanner's own doc says a subcommand it has no manifest for is "silently
+# skipped, there is no ground truth to validate them against". That is the
+# right behavior here and it does not happen, because the PARENT matched.
+#
+# Known upstream and deliberately left open: gascity 7724983de's own body lists

+#     command on the left of the pipe.
+#   - `--rig` and `--city` belong to `gc bd`, which strips them in

+"""Stand a pack up in a scratch city and ask a real `gc` binary about it.
+
+A pack's own unit tests read its TOML and confirm the file parses. `gc lint`
+reads one pack in isolation. Neither can say what Gas City does when it loads
+that file into a city, which is the only place a user meets a pack -- and the
+gap is not theoretical: every pack we maintain linted clean while `pr-pipeline`
+put a deprecation warning into `gc doctor` for every city that imported it.
+
+This module is the shared harness for tests that close that gap. It offers three
+things a caller composes:
+
+`write_city` builds a throwaway city that imports whatever packs the caller
+names, at city scope, rig scope, or both.
+
+`attributable` runs `gc doctor` twice -- once against that city, once against a
+baseline city with the same shape and no packs under test -- and returns the
+difference. A doctor run on a developer's machine reports a couple of dozen
+findings that have nothing to do with any pack (no tmux, no bead store, no git
+in the scratch rig). Hand-listing them would be a waiver set that rots.
+Subtracting a baseline cancels them without naming any of them.
+
+`write_canary_pack` is the control every caller of `attributable` owes. An empty
+delta is also what a doctor that stopped reporting produces, and what a city
+that failed to load before doctor reached the packs produces. The canary is a
+pack whose formula declares a deprecated contract on purpose, so a test can
+require the subtraction to surface a known finding through this fixture shape,
+on this binary, in this environment.

+"""Run the shipped default-branch resolution against real git repositories.
+
+Four assets resolve a repository's default branch: the `prepare-worktree`
+workflow step in the `gascity` pack, and the guard that refuses to ship from
+the default branch in `contributing` and twice in `pr-pipeline`. All four used
+to do it with `git remote show origin`, which contacts the remote on every
+invocation.
+
+This test does not assert that the files contain a particular string. It pulls
+the shell out of the shipped asset and runs it under `sh` against git
+repositories built on disk, so a passing result is a statement about what the
+shipped code does, not about how it is written.
+
+The repositories here use a default branch named `trunk` on purpose. `main` is
+the answer a broken resolution reaches by accident, through the hardcoded
+fallback, so a fixture on `main` cannot tell a working resolution from a
+failing one.

+"""Hold `gc lint gastown` at a pinned finding set.
+
+gastown is a supported pack. It is exercised by supported-pack-nightly.yml and
+it is NOT in the `gc lint` loop in .github/workflows/ci.yml, which is how it
+accumulated fourteen findings that nothing failed on: nine prompt templates and
+formulas telling agents to run bd flags that do not exist, and five pack-level
+diagnostics.
+
+Seven of those were real and are fixed. The rest are defects in gc's own
+linter, enumerated with their gc-side cause in
+`tests/gastown_lint_upstream_defects.txt`.
+
+A NEW finding fails, which is the regression this exists to catch. A pinned
+finding that DISAPPEARS also fails, because that is the upstream fix landing
+and the waiver should be deleted in the same change rather than quietly
+outliving it.
+
+Which findings gc emits depends on which gc ran, and this test does not paper
+over that. `.github/workflows/ci.yml` installs `gc@latest`; twenty-two findings
+that a released gc reports were fixed on gascity main by 7724983de and are
+absent from a dev build. So the waiver file is sectioned: entries every gc
+reports are required, and a version-dependent section is tolerated but has to
+be wholly present or wholly absent. That is what the sections are for, and it
+is why the first run of this test in CI went red while it was green locally.
+
+Fidelity, and where it stops: this runs the real `gc lint` against the real
+pack, so it is not a fixture reimplementation of the linter and it cannot drift
+from it. What it cannot do is check a flag `gc lint` does not know about --
+internal/bdflags/bdflags.go carries a manifest of bd subcommands, and anything
+outside that manifest is skipped by design. It is also line-oriented and does
+not join backslash-continued shell lines, so the three multi-line `gc bd create
+... \\ --labels=warrant` invocations fixed alongside this test were never
+reported by it at all. A green here means "no NEW finding of a kind gc lint can
+see", not "every bead command in the pack is valid".

+"""Every pack we maintain, stood up in a city and asked about by a real `gc`.
+
+These five are the packs users actually install, and the ones we have committed
+to keeping working. Each is imported on its own here, because each is imported
+on its own by a user -- nobody installs "the maintained set". The whole point of
+running them separately is that a break in one is attributed to that one.
+
+What each pack gets:
+
+* its declared surfaces, derived from its own directory rather than listed here,
+  resolved through a running `gc` in a city that imports it;
+* a `gc doctor` delta against a baseline city, asserted by set EQUALITY against
+  what that pack is currently expected to add. Equality rather than emptiness
+  because a legitimate finding exists (an adapter binary a pack cannot ship
+  built), and equality rather than `assertFalse` on new items because a finding
+  that DISAPPEARS is also news: it means either the pack stopped declaring
+  something or `gc` stopped checking it.
+
+The control lives in `test_the_doctor_delta_can_surface_a_finding` and every
+delta assertion here depends on it. An empty or unchanged delta is also what a
+doctor that stopped reporting produces.
