 ### Upgrading Notes
 
-- **Every graph-owning store scope needs a `Dir`-matched `control-dispatcher`
-  agent.** Control beads now route to the dispatcher that owns their store scope
-  (city vs. rig) rather than falling back to the city dispatcher, and that
-  routing is fail-closed: a graph owned by `rig:X` whose scope has no exactly
-  `Dir`-matched `control-dispatcher` agent now fails before instantiation with an
-  `OrderFailed` event instead of silently stranding its control lane on a
-  dispatcher that cannot read the rig store. Deployments that previously limped
-  along through shared-store mis-routing must add a matching rig-scoped
-  `control-dispatcher` agent; the reconciler logs `control bead <id> in rig
-  store "X" has no configured control-dispatcher for its store scope` to name
-  the missing scope.
+- **Configure one store-scoped `control-dispatcher` for every graph-owning
+  scope.** Formula control beads now route to the dispatcher whose `Dir`
+  matches the city or rig store that owns the graph. A rig-owned graph with no
+  matching dispatcher fails before instantiation instead of falling back to a
+  dispatcher that cannot read its work.
+- **Run `gc doctor --fix` after upgrading an existing city.** The current
+  doctor converges pack imports, provider catalogs, project identity, retired
+  hold labels, and managed beads/Dolt metadata before the orchestrator starts.
+- **Upgrading over an older install at a different path may need a manual
+  reseed.** If a machine already ran an older `gc` (for example a Homebrew
+  binary now replaced by a source build at a new path), `gc start` can keep the
+  stale supervisor running and can fail closed on a present-but-invalid
+  bundled-pack cache — only an *absent* cache self-heals. Run `gc import
+  install` to repopulate the cache, then let `gc start` auto-restart the
+  supervisor (or on Linux `systemctl --user restart gascity-supervisor`).
+- **An unrelated stale registered city can block `gc start`; fix or unregister
+  that city — not the one you are starting.** A pre-1.3 city still registered
+  with un-migrated provider config (for example `workspace.provider = "claude"`
+  with no `[providers.claude]` block) can fail the registry scan and abort
+  startup, with a misleading hint to `gc init` the healthy city you were
+  actually starting. Run `gc doctor --fix` inside the offending stale city, or
+  `gc unregister <stale-city>` to drop it.
+- **macOS: a supervisor left running from a prior version may need a manual
+  restart.** macOS cannot resolve a direct (non-launchd) supervisor's
+  executable for binary-drift detection, so the automatic post-upgrade restart
+  may not complete. Run `gc supervisor stop --wait`, then `gc start`.
+
+### Added
+
+- **A run-centered dashboard and API.** Run detail now combines the formula

+- **Privacy-scoped command-usage metrics in release artifacts.** Before the
+  first eligible interactive command is recorded, `gc` shows the complete

+  operating system, and an anonymous installation ID—never arguments, paths,
+  file contents, or environment values. `gc metrics status`, `example`, `on`,
+  and `off` expose the local controls; `DO_NOT_TRACK=1` and
+  `GC_DISABLE_USAGE_METRICS=1` provide environment-level opt-outs.
+- **Broader runtime composition.** Provider routing, ACP/automatic runtime

+- **Production workflow controls.** Formulas v2 gained stronger retry,
+  fan-out, drain, scope, artifact, and finalization behavior, plus better live
+  status and event evidence for operators.
+- **An experimental OpenClaw bridge proof of concept.** The private package
+  under `contrib/openclaw-bridge` explores iMessage and Telegram connectors; it
+  is not a supported provider pack or a shipped connector artifact.
+
+### Changed

+- **Session lifecycle operations converge through the worker boundary.** Pool
+  demand, wake, resume, drain, close, and orphan recovery now reason from
+  persisted session/work identity rather than provider-specific shortcuts.
+- **Beads remains the persistence boundary while storage becomes more
+  resilient.** Native and CLI-backed stores share transactional lifecycle
+  semantics, bounded cached reads, store-aware routing, and explicit degraded
+  results across city and rig scopes.
+- **CI and local verification are sharded and event-driven.** The release gate
+  includes fast units, process tests, integration packages, tutorials, real
+  inference acceptance, and macOS regressions without one monolithic test
+  process.

-# Gas City Testing Philosophy
+# Gas City Testing Policy
+
+This file is the canonical, normative source for how Gas City tests are
+designed, placed, reviewed, and timed. If an older plan, audit, or contributor
+document conflicts with this policy, this file wins. Existing exceptions are
+debt, not precedent. In this document, an **owner** is a tracking bead with a
+current assignee. An approved waiver must also name its reason, replacement
+proof, and expiry.
+
+The
+[testing efficiency operating corpus](engdocs/contributors/testing-efficiency-workflow-corpus.md)
+is the non-normative workflow, evidence catalog, and team handoff for applying
+this policy.
+
+### Policy versus enforcement today
+
+The rules below are normative even where automation is still being built. Do
+not describe a target as an existing gate.
+
+| Policy area | Mechanical status today |
+|---|---|
+| Sleep/process/listener/tmux/env/CWD growth | Checked by the source-resource ledger below |
+| Runtime constructor and `runtime.Fake` conformance binding | Checked by the runtime provider ledger below; several explicit waivers remain |
+| Other provider conformance | Shared suites exist, but exact production-constructor coverage is still a manual audit with known gaps |
+| Sub-five-minute PR feedback and timing ratchets | Target; current Go timing artifacts measure test execution, not workflow queue/bootstrap/graph time (`ga-80po0c.4`) |
+| Large/E2E ownership and cadence | Target; the executable manifest is owned by `ga-80po0c.6` |
+| First-attempt flake and quarantine policy | Target; required Playwright retry and legacy unledgered skips remain noncompliant debt under `ga-80po0c` |
+
+## The outcome: protected PR feedback in under five minutes
+
+The developer-visible service-level objective is p95 **under five minutes**
+from GitHub Actions PR-workflow creation until the required automated `CI`
+summary reaches a terminal conclusion. Compare the latest 20 non-superseded
+full-union runs on the same runner-policy cohort; include failed and timed-out
+attempts, and exclude only obsolete-SHA concurrency cancellations. Queueing is
+part of the developer-visible metric and is also reported separately. The
+execution sub-budget, from the first required job entering `in_progress` until
+`CI / required` completes, is p95 at most 4m30s. Current telemetry does not yet
+enforce this SLO; `ga-80po0c.4` owns that gap.
+
+The budget changes where a proof runs, never whether an important risk is
+proved:
+
+- Required PR lanes should contain fast, deterministic proofs plus the
+  relevant real boundaries. Current integration routing is coarse and the
+  dashboard job is unconditional; treat that as optimization debt, not the
+  desired endpoint.
+- Broader real-provider and full-composition proofs run on `main` when they
+  cannot fit the PR budget.
+- Credentialed, live-inference, cloud, and soak journeys belong in scheduled
+  or explicit profile lanes. The full live-inference profile matrix is
+  currently local-only; do not claim nightly coverage for it.
+
+A slow PR test may move to a later lane only after lower layers own its branch
+and error-detail matrix. The later lane must retain any unique real-composition
+risk. Moving a test without that ownership map is deleting quality, not
+improving feedback.
+
+## The authoring rule: one risk, one smallest owning proof
+
+Start with a single sentence describing the regression the test must catch.
+Then put that assertion at the smallest layer that can fail for the intended
+reason. A higher layer may prove wiring across a boundary, but it must not
+repeat the lower layer's branch matrix.
+
+Classify the observable promise first:
+
+1. **Behavior promised by a provider interface?** Add the case once to its
+   shared conformance suite and run that suite against every production
+   implementation with distinct behavior and every reusable fast substitute.
+2. **Implementation-only decision or domain transition?** Write a unit test
+   next to the code.
+3. **User-visible CLI parsing, output, or exit status?** Use testscript with
+   fast providers.
+4. **Ordering or argument plumbing between components?** Write one focused
+   coordination test with recording collaborators.
+5. **Real process, protocol, filesystem, database, browser, or provider
+   composition?** Keep one integration or end-to-end proof for that boundary.
+6. **Documentation-to-code agreement?** Put the invariant in `test/docsync`.
+
+The question is not “where can this test be made to pass?” It is “which layer
+uniquely owns this risk?” Search for an existing owner before adding a test. If
+one exists, strengthen or parameterize it instead of creating another journey.
+Conformance is a reusable testing pattern rather than a sixth execution tier:
+one contract suite is intentionally executed against multiple implementations.
+
+### RED, GREEN, refactor, measure
+
+Every behavior change and bug fix follows this loop:
+
+1. **RED:** add the smallest owning test and observe it fail for the intended
+   reason. For a bug, reproduce the reported failure before changing code.
+2. **GREEN:** make the narrowest production change that satisfies the test.
+3. **Refactor:** improve names and boundaries, remove duplicate assertions,
+   and replace expensive collaborators with proved substitutes.
+   A behavior-neutral migration records a PR-description table from every
+   retired assertion to its new owner and retained real-boundary proof. Before
+   commit, delegate independent reviews of semantic parity, speed/resource
+   policy, and repository accuracy/enforceability.
+4. **Measure:** repeat the focused test and run the affected shard. Record
+   before/after wall time when adding, moving, or materially changing tests.
+5. **Verify the boundary:** run the focused owner plus the relevant
+   conformance, coordination, or integration owner.
+
+Never write the large end-to-end test first merely because the production code
+has no seam. Refactor the code so the policy can be exercised directly, then
+retain the smallest real-boundary proof that demonstrates the wiring.
+
+## Design production code for fast proofs
+
+Core logic receives dependencies; outer constructors choose production
+implementations. Prefer an existing provider port. For one isolated side
+effect, inject a function value. Introduce a new interface only when it is a
+stable domain boundary **and** has at least two real implementations,
+consistent with Gas City's no-premature-abstraction rule.
+
+| Source of nondeterminism | Fast seam | Keep real coverage for |
+|---|---|---|
+| Bead or domain persistence | `beads.Store`, usually `beads.MemStore` in consumer tests | Store conformance and provider lifecycle |
+| Wall-time/deadline decisions | Injected clock, including `clock.Fake` | The real-clock adapter, not every consumer |
+| Timers, sleeps, scheduling, backoff | Injected timer/sleeper/scheduler or `testing/synctest` | The timer adapter, not every consumer |
+| Asynchronous completion | Channel, callback, event watcher, or notifier | One public protocol/event-stream composition |
+| Subprocess execution | Narrow executor function/interface with scripted results | Argument-to-real-binary compatibility |
+| Generated IDs or randomness | Injected generator with deterministic values | Format/entropy adapter contract |
+| Filesystem operations | `fsys.FS`, normally `fsys.Fake` for consumer logic | `fsys.OSFS` conformance and OS-specific semantics |
+
+Environment variables, current working directory, global clocks, package-level
+mutable state, and executable discovery belong at composition edges. Unit tests
+must not need them to steer domain behavior. Use `t.TempDir()` when the real
+filesystem is itself relevant; otherwise prefer `fsys.Fake`.
+
+## Choose meaningful failure edges, not Cartesian products
+
+Test each distinct obligation at its owner. For a typical operation, consider
+only the applicable boundaries:
+
+- invalid input or an absent required value;
+- collaborator unavailable before any side effect;
+- partial success requiring rollback, idempotency, or recovery;
+- cancellation or deadline propagation;
+- a concurrency conflict or lost-update boundary;
+- serialization or protocol incompatibility;
+- restart/reconnect behavior at a real provider lifecycle boundary.
+
+Equivalence classes beat exhaustive combinations. If five commands use the
+same store port, test the shared store failures in conformance, each command's
+distinct response in a unit test, and one command-to-real-store composition.
+Do not multiply every command by every provider by every error. Add another
+combination only when it represents a different contract. An escaped
+regression must first populate the missing equivalence class at the smallest
+owner; retain its high-level reproduction only when the defect uniquely
+depends on that composition.
+
+## Asynchronous tests wait for facts, not elapsed time
+
+New or modified tests must not use `time.Sleep` to wait for work to “probably”
+finish, and must not add open-coded polling loops. Instead:
+
+- expose a completion/error notification and select on it with a context;
+- capture the event cursor and subscribe before triggering work, then correlate
+  terminal success or failure by request/resource ID, close the subscription,
+  and reread durable state;
+- use a fake clock or `testing/synctest` for timers, retries, and backoff;
+- use a barrier/channel to prove a goroutine reached a state before releasing
+  it; and
+- assert the terminal state immediately after the notification.
+
+Polling is allowed only at a true black-box boundary that exposes no completion
+signal and where adding one would change the public contract. Such polling must
+use a shared helper with a context-aware ticker or bounded backoff, fail with
+the last observed state, and have one named boundary owner. Busy loops and a
+fixed sleep before the helper are forbidden. The deadline rule below supplies
+safety timeouts; those deadlines must not determine the normal test duration.
+
+## Test doubles and conformance are one contract
+
+A fast substitute is trustworthy only when it is held to the same observable
+contract as production. When a provider method or invariant changes:
+
+1. change the shared conformance suite first;
+2. run it against every behaviorally distinct production implementation or
+   composition for that port;
+3. run it against every reusable fast substitute; and
+4. keep implementation-specific tests only for behavior outside the shared
+   contract.
+
+Thin aliases that add no state, transformation, or behavior may use a focused
+exact-constructor wiring proof instead of repeating the full suite. The checked
+runtime ledger remains authoritative for runtime compositions.
+
+Skips do not count as conformance. A temporary incompatibility must be recorded
+as an explicit waiver with a tracking-bead owner, reason, replacement proof,
+and expiry. Constructor wrappers and provider compositions need coverage for the
+actual production path; proving a nearby raw implementation is not
+enough.
+
+Fakes need only model observable contract behavior used by consumers. They do
+not simulate implementation internals. Add recording only when call order or
+arguments are themselves the contract; a stateful fake is not automatically a
+spy.
+
+## Keep the critical end-to-end portfolio deliberately small
+
+An end-to-end test is admitted only when all of these are true:
+
+- it protects a high-value user journey or high-blast-radius recovery path;
+- the risk exists only when multiple real boundaries are composed;
+- lower layers already own the branch and error-detail matrix;
+- its assertions use stable public outcomes rather than internal timing;
+- it has hermetic setup, targeted cleanup, actionable diagnostics, and a named
+  owner; and
+- its lane and measured duration fit the cadence above.
+
+Each major effort must point to an existing critical journey or add the one
+missing composition proof. It does not receive a new E2E for every acceptance
+criterion. Before admitting an E2E, list the lower-layer owners it relies on
+and the unique cross-boundary failure it catches. When two journeys catch the
+same regression, keep the clearer and faster one.
+
+Record the journey, unique risk, lower-layer owners, path triggers, lane,
+budget, diagnostics, and owner in the checked E2E/provider manifest owned by
+`ga-80po0c.6`. Until that manifest lands, put the same fields in the PR
+description. On-demand coverage does not count as a release proof without a
+freshness gate for the exact release SHA.
+
+## Flakes are defects
+
+A deterministic product-test failure may not be retried into green on the same
+tested SHA. Repetition is useful for diagnosis, but a required gate must retain
+the worst product-test status across attempts. A pre-test runner/service outage
+may be retried only when classified with attached infrastructure evidence; it
+is reported separately. A code change produces a new SHA and a new result. The
+failure has one tracking-bead owner until fixed.
+
+Quarantine is forbidden until a checked ledger exists. Any future quarantine
+must include a tracking-bead owner, captured failure evidence, nonblocking
+still-failing lane, replacement coverage, and expiry that fails CI;
+quarantined coverage cannot satisfy a required gate. Capability-based local
+skips likewise require an equipped CI execution or an explicit waiver. Do not
+weaken assertions, increase sleeps, or broaden retries to hide an unknown race.
+Remove redundant tests; repair unique tests.
+
+## Timing objectives and resource ratchets
+
+Test performance claims require evidence. For a focused change, run the test
+repeatedly with the result cache disabled (for example, the command below) and
+time the relevant sharded target. This is focused diagnostic evidence, not an
+authoritative p95; the history format requires twenty comparable successful
+samples for an authoritative p95.
+
+```bash
+go test -count=10 -run '^TestName$' ./path
+```
+
+Compare like runner, OS, architecture, CPU count, cache condition, and suite
+variant. A single warm-cache run is diagnostic, not a regression baseline.
+
+No change may knowingly push the protected graph above its SLO. Once trusted
+history and workflow telemetry are authoritative, checked per-profile
+baselines must fail material regressions and lower after sustained
+improvements; increases require an expiring waiver. Until then, include
+before/after observations in the PR and treat the timing tools below as
+shard-balancing evidence rather than enforcement.
+
+The checked source-resource ledgers below are anti-growth ratchets for sleeps,
+processes, listeners, environment mutation, and CWD mutation. Reductions lower
+the checked baseline; new debt requires the same explicit, expiring policy
+change as any other waiver.

+#### PR static-check scope
+
+The `preflight-static` job has two fail-safe scopes. Only an effective
+`pull_request` event whose default checkout is validated as GitHub's two-parent
+synthetic merge, with its first parent equal to the event's exact base SHA, may
+use the changed scope. The checkout keeps the default `GITHUB_SHA` and uses
+`fetch-depth: 2` so that validation is local and exact. A missing or different
+base, a non-merge checkout, or an unknown event selects the full scope.
+
+Pushes to `main`, schedules, manual dispatches, and every other non-PR event run
+the full static suite. Reusable workflows inherit their caller's event; the
+reusable call itself grants no changed-scope exemption. An effective
+`pull_request` event may still qualify after the same synthetic-merge
+validation, while an invocation such as the current RC `workflow_dispatch`
+remains full. The classifier never guesses a base from `origin/main` or a
+merge-base calculation.
+
+Even a validated PR merge runs the full scope when its diff touches static
+analysis or build policy:
+
+- `go.mod`, `go.sum`, `go.work`, or `go.work.sum`
+- any root `.golangci.*` configuration or `Makefile`
+- `.github/workflows/**`, `.github/actions/**`, or `.githooks/**`
+- `vendor/**` or `scripts/cipolicy/**`
+- `scripts/ci-static-scope` and `scripts/ci-static-select`
+
+The two scopes own different commands:
+
+| Scope | Commands | Selection guarantee |
+| --- | --- | --- |
+| Changed PR | `make lint-affected`, `make fmt-check-changed` | Lint and vet every package owning a changed Go build input or embedded file, every native package that could consume a changed path, and all transitive reverse dependents; format-check only changed regular `.go` files that still exist. |
+| Full/fail-safe | `make lint`, `make fmt-check`, `make vet` | Analyze and format-check the whole repository, then run standalone `go vet ./...`. |
+
+Affected-package discovery examines every changed path. It selects packages
+for changed Go-tool build inputs (`.go`, `.c`, `.cc`, `.cpp`, `.cxx`, `.m`,
+`.h`, `.hh`, `.hpp`, `.hxx`, `.f`, `.F`, `.for`, `.f90`, `.s`, `.S`, `.sx`,
+`.swig`, `.swigcxx`, and `.syso`) and maps changed embedded files to every
+owning package using `EmbedFiles`, `TestEmbedFiles`, and `XTestEmbedFiles` from
+the canonical records in one complete
+`go list -mod=readonly -test -json ./...` graph.
+Additions, modifications, deletions, and both sides of cross-package moves are
+included. Git rename coalescing is disabled so a move cannot hide the old
+package. Native compiler include and linker inputs can have recognized or
+arbitrary names and may live outside their consuming package. Every changed
+path therefore selects every package with native Go-tool sources, plus their
+reverse dependents. This is the smallest sound scope available without trying
+to duplicate compiler-specific dependency discovery. An unrelated non-build,
+non-embedded path remains a no-op when the graph has no native package that
+could consume it.
+
+Reverse dependents are included because analyzers such as `govet` consume
+exported facts, including through test-only imports. If the package graph
+cannot be loaded completely, affected lint fails safe to `./...` instead of
+trusting a partial graph. This includes a deleted required embed input. A
+deleted glob member no longer appears in the current resolved embed inventory,
+so a deletion that may match any current `EmbedPatterns`, `TestEmbedPatterns`,
+or `XTestEmbedPatterns` entry fails safe even when a nested package still owns
+the deleted build-input directory. Any other deletion beneath a package that
+has neither a current embed owner nor a current direct package owner also fails
+safe to full scope. These guards run before native shared-input shortcuts,
+including for recognized headers. File selection is NUL-delimited. Formatting
+remains limited to
+changed `.go` paths, excludes deletions and symlinks, accepts only existing
+regular files, and never invokes the formatter with an empty file list.
+
+`lint-affected` is the conservative PR target. It runs the configured
+golangci linters, including golangci's `govet`, then runs the Go tool's `vet`
+over the exact same affected package closure. The bounded duplicate preserves
+both tools' distinct diagnostics without repeating either analysis across the
+whole repository. It also retains standalone-vet diagnostics in generated
+files and unchanged reverse dependents. If selection fails, the same pair runs
+over `./...`; fallback never disables configured linters. `lint-changed`
+remains the faster local/pre-commit target and intentionally checks only
+packages that contain changed Go files. Both accept `LINT_CHANGED_SCOPE` and
+`LINT_CHANGED_REF`; CI uses `tracked` and the event's exact PR base SHA.
+
+The golangci configuration enables `govet` explicitly in both scopes.
+Golangci's `govet` execution is not assumed to be semantically equivalent to
+standalone `go vet`: generated-file exclusions and analyzer/configuration drift
+can differ. Full-scope runs therefore retain standalone `go vet ./...`, while
+the changed lane invokes standalone vet on its conservative closure.
+
+`make test-ci-policy` runs independently of changed/full static selection and
+always executes the focused workflow-scope, golangci-`govet`, affected-target,
+and fail-closed-classifier contracts. A self-binding test in the existing CI
+policy package rejects any Makefile change that removes this focused Go suite
+from the target.

+#### Local timing-plan dry runs
+
+The local planner consumes the current runnable inventory, the canonical
+schema-v1 timing snapshot above, and planner configuration without changing
+the active shard topology:
+
+```bash
+go run ./scripts/test-timing-plan.go \
+  --inventory runnable-inventory-v1.json \
+  --history timing-history-v1.json \
+  --config timing-plan-config-v1.json \
+  > timing-plan-v1.json
+```
+
+Inventory and configuration are independently versioned. The minimal inventory
+is `{"schema":1,"units":[{"unit_id":"package:TestName"}]}`. Configuration
+schema v1 supplies one exact comparable profile, a shard count, a p95 cap, and
+shared conservative fallback estimates for that suite/profile invocation. The
+profile key is the complete `(job, variant, runner label, OS, architecture,
+CPU count)` tuple; profiles are never merged or selected by a nearest-runner
+heuristic. All three inputs reject missing or unsupported schemas, unknown
+fields, trailing JSON values, and `null` where a contractual array is required.
+
+The current inventory is the only authority for runnable membership. Every
+inventory unit is assigned exactly once, and stale timing rows cannot add work.
+An exact profile match contributes history. If the requested profile is absent,
+the command still produces a complete static plan and records
+`history_profile_status: "profile-missing"`; multiple copies of one comparable
+profile are malformed and fail. Snapshot counts, identities, nullable
+statistics, observations, and authority flags are validated before planning,
+including rows for units no longer in the inventory.
+
+History becomes planner-usable in two stages:
+
+- Before five successful samples, p50, p75, and variance use the configured
+  static fallback. At five samples, the empirical values become usable.
+- Before twenty successful samples, p95 is
+  `max(static_p95, 1.5 * selected_p75)`. At twenty samples, empirical p95
+  becomes usable.
+
+Units are sorted deterministically by descending p75, p95, variance, and p50,
+then stable unit ID, and placed in the shortest p75 shard that remains within
+the aggregate p95 cap. No unit is dropped: an individually oversized unit is
+marked `p95-cap-exceeded`, while unavoidable aggregate overflow is marked
+`shard-p95-cap-exceeded`. Equivalent shuffled inputs therefore emit identical
+canonical JSON.
+
+The output is explicitly marked `authority: "dry-run"`. This command reads only
+the three named files and writes the plan to stdout. It does not read GitHub
+state, authenticate protected provenance, write timing history, publish
+`ci-metrics`, perform path gating or hysteresis, decide required lanes, or
+activate workflow/shard execution. Those remain deferred to the trusted
+control-plane workflow.

+#### Cross-invocation concurrency bound via push-gate slots
+
+The three resource-control axes are orthogonal: (1) within-run job sizing
+(`LOCAL_TEST_JOBS`/`scripts/test-local-job-count`, above), (2) per-invocation
+resource isolation (`gascity-test.slice`, above), (3) cross-invocation
+concurrency bound — this section. Axes 1 and 2 both operate *within* a
+single `test-local-parallel` invocation; neither stops multiple invocations
+(a push, a direct `make`, and a CI job, say) from landing on the same host
+at once. Two measured incidents (2026-07-14, load 88.07 with 5 concurrent
+`test-fast-parallel` runs + 2 gates + 1 `make test`; a later run at load
+53.6-82.1 with ~20 concurrent gate processes) showed exactly that: nothing
+bounded how many heavy-suite invocations could run concurrently, producing
+false-red failures (timeouts, OOM-adjacent slowdowns) indistinguishable
+from real regressions.
+
+`scripts/test-local-parallel` — the one place all four heavy targets
+(`fast`, `cmd-gc-process`, `integration`, `full`) funnel through — acquires
+one of `PUSH_GATE_MAX_CONCURRENT` (default 2) numbered `flock(1)` slots
+under `<city_root>/.gc/gate-slots` (or, outside a city, the repository's
+common git dir — `<repo>/.git/gate-slots` in a normal clone, and the one
+shared common dir for all of a repo's linked worktrees) before running any
+jobs, and holds it for the invocation's entire
+lifetime. The mechanism (`scripts/push-gate-lock-lib.sh`) is adapted from
+`packs/maintainer-pr-review/scripts/run-lock-lib.sh`'s
+`mpr_acquire_global_slot` in the gc-management meta-repo, with one
+deliberate difference: mpr's caller fails fast, but this gate's caller is
+synchronous and human/agent-facing, so on contention it polls with a
+bounded wait (`PUSH_GATE_MAX_WAIT_SECONDS`, default 600s; polling every
+`PUSH_GATE_POLL_SECONDS`, default 15s), printing an immediate diagnostic
+naming current slot holders the moment it starts waiting. Exhausting the
+wait maps to `exit 75` (`EX_TEMPFAIL`) — distinct from a real test failure
+and from `scripts/push-ownership-guard.sh`'s unrelated `exit 1` contract for
+bead-ownership staleness. That 75 is only visible to callers that invoke
+`scripts/test-local-parallel` directly: the four Makefile targets and
+`.githooks/pre-push` (`exec make test-fast-parallel`) run it under `make`,
+which reports `make: *** [test-fast-parallel] Error 75` and then exits 2.
+Through those paths the distinguishing signal is the stderr text, not the
+process exit code. The kernel releases the lock automatically when the
+holding process exits — success, failure, or crash alike — so a stale slot
+can never survive a dead holder; no PID-file liveness probing is involved.
+FD inheritance into test jobs is severed at the fan-out boundary, so a slot
+that stays locked past its gate means a leaked descendant is still holding
+the descriptor (`lsof` on the slot file names it), not a stale file to
+delete. The gate needs `flock(1)`, which `docs/getting-started/installation.md`
+already lists as required; if it is absent the run proceeds uncapped with a
+warning rather than blocking. `GC_PUSH_GATE_NO_CAP=1` bypasses the cap
+entirely for one invocation.
+
+The slot mechanics are covered by `scripts/test-push-gate-lock.sh`, run
+directly as the `push-gate-lock-selftest` job inside `test-local-parallel`
+itself (`fast` and `full` modes) rather than through a `go test` trampoline.
+A trampoline's `exec.Command` call would itself add a tracked subprocess
+occurrence to `internal/testpolicy/resourcecensus`'s baselines — including
+the `scope=all` audit row, which fails on any change, growth or shrinkage
+alike, with no per-file exemption available — so driving the script as a
+plain shell job avoids that ratchet entirely instead of bumping it.
+
+Only `scripts/test-local-parallel` is wired to this gate — the same targets
+axis 2 leaves unconfined (`test-acceptance*`, `test-integration`,
+`test-integration-huma`, `test-worker-*`, `test-cover`, and similar direct
+`go test` invocations) are outside this bound too.
+
+This mechanism does not extend `bd` claim-lease heartbeats across the
+wait+run phases. An earlier draft of the originating bead (`ga-owh20p`)
+assumed an existing bd-heartbeat workaround needed extending for this
+purpose; no such mechanism exists in this codebase (`bd heartbeat` leases
+are node-local and ephemeral, never committed to Dolt, so extending them
+here would be a no-op). The underlying claim-staleness concern this would
+have addressed is tracked separately under `ga-aw5356`, not here.

+it and points `baseURL` at it, so the SPA and its same-origin `/v0` + `/api`
+surfaces are hosted by one handler (no CORS or base-URL override). Each spec
+drives a route (Home, Runs, the seeded run detail — the regression view —,

+content renders, **no** React error boundary
+(`components/ErrorBoundary.tsx`) is shown, and **no** client-error POST

+in a real browser against a real HTTP supervisor, so it exercises the full

-result AND the call sequence:
+Some fakes also record calls as `[]Call` structs. Verify interactions only when

 }
 ```
 
 ### Error injection strategies

+**Modal errors** (`runtime.Fake`, `mail.Fake`) — whole-provider
+unavailability. `events.NewFailFake()` fails reads and watches but still records
+events because `Recorder.Record` cannot return an error:
 ```go
-f := runtime.NewFake()
-f.Broken = true // Start/Stop/Attach and related operations return errors

 ### Compile-time interface checks
 
-Every fake has a compile-time assertion in its test file:
+An explicit compile-time assertion is useful for a provider or adapter:
 
 ```go
 var _ Provider = (*Fake)(nil)
 ```
 
+The conformance factory also proves interface assignability. Neither form

+// its body here is additive: the exact query-string shape from
+// workflowServeControlReadyQueryForBeads is unchanged (still asserted upon by

+// hangBudget is the single wall-clock ceiling shared by every test-side wait in
+// this package.
+//
+// It is a HANG DETECTOR, not a latency assertion. No test in this package waits
+// on it to prove the system is fast: the real assertions always come after the
+// wait returns. Nothing waits the budget out on a passing run either, because
+// awaitClose and awaitCond return the instant their condition is met — so
+// raising this number does not make the suite slower, and lowering it does not
+// make the suite stricter. It only changes how long a genuinely wedged test
+// takes to report.
+//
+// DO NOT tune hangBudget to make a failing test pass. A test that needs to
+// assert a latency bound must keep its own explicit deadline plus a comment
+// saying which bound it asserts, or be written as a benchmark. A test that
+// needs to assert a negative ("nothing arrives within X") must likewise keep
+// its own short deadline — hangBudget is the wrong tool there and would add a
+// full minute of dead wait.
+//
+// RELATIONSHIP TO testutil.GoroutineRaceTimeout — these are not competing
+// constants, which is why hangBudget is derived from it rather than declared
+// alongside it. TESTING.md's "Test deadline rule" makes GoroutineRaceTimeout
+// the MINIMUM safe deadline for a timer racing a goroutine ("must be >= 10s").
+// hangBudget is the point at which this package declares a wedge, which is a
+// ceiling, not a floor. Use GoroutineRaceTimeout directly when a test needs a
+// deadline that satisfies the rule; use awaitClose/awaitCond when the wait is
+// purely a hang detector and no assertion depends on how long it took.
+//
+// Why the floor alone is not enough here: measured under single-core CPU
+// starvation, the guarded regions in this package took 18.0-19.8s to complete
+// (ga-h51wa1). A 10s deadline would have failed all eight of those runs even
+// though nothing was wedged. The multiplier gives roughly 3x headroom over the
+// worst run actually observed; Go's package -timeout remains the real backstop.
+// This constant exists only so a wedged wait fails at the line that wedged,
+// with a useful message, instead of taking the whole package down with an
+// unattributed timeout.
+const hangBudget = 6 * testutil.GoroutineRaceTimeout

+// convergence. In production, where the controller is alive on the API path, the
+// same probe returns true, so the lanes stay converged there too. remote and
+// alive still match (A==B), and all three now match on HQ Running.

+// The city has no rigs, isolating the HQ-entry divergence and avoiding the
+// tmux/session probe path (rigListSessionProvider is only built when rigs exist).

+Some databases are deliberately local — a privacy boundary, or a store whose

+every remote path.

+Choose `.no-sync` over `--skip-fetch` when a database must never reach a

+### Claim Identity Convention
+
+The `AssignedInProgressQuery` (Tier 1) and `RoutedPoolQuery` (Tier 3) rows
+above are rendered once, at session start, from Go `text/template`
+variables. But the *literal* prompt text written into `prompts/*.md.tmpl`
+files also references two OS environment variables directly — `$GC_TEMPLATE`
+and `$GC_ALIAS` — which the agent's own shell commands expand at run time,
+not at template-render time. These are a separate injection mechanism from
+the table above, and the two env vars are not interchangeable:
+
+- `$GC_TEMPLATE` is the qualified template identity, shared by *every* live
+  session of that template (the named-session holder and every pool slot
+  alike).
+- `$GC_ALIAS` is the current session's own concrete identity — the bare
+  qualified name for a named holder or canonical singleton slot, or the
+  suffixed `-N` identity (e.g. `rig/builder-1`) for a pool slot.
+
+Convention for which one to use in a prompt template's startup section:
+
+| Line | Token | Why |
+|---|---|---|
+| Tier 1 (crash-recovery query) | `${GC_ALIAS:-$GC_TEMPLATE}` | Ownership read — must resolve to *this session's own* prior claim, not a sibling's. |
+| Claim (`bd update <id> --claim --assignee=...`) | `${GC_ALIAS:-$GC_TEMPLATE}` | Ownership write — must stamp *this session's* concrete identity. |
+| Tier 2 (pre-assigned ready-work query) | bare `$GC_TEMPLATE` | Shared role discovery — pre-assigned work is deliberately assigned to the bare template. |
+| Tier 3 (routed-pool queue query) | bare `$GC_TEMPLATE` | Shared queue key — `gc.routed_to` is a role-level routing target, not a per-session claim. |
+
+Getting this wrong is not cosmetic: a template that is both a
+`[[named_session]]` and a multi-slot pool has more than one live identity
+sharing a single template string. If Tier 1 or the claim line uses the bare
+template, two sessions can independently "recover" or adopt the same
+in-progress bead and both complete it — duplicate commits, duplicate PRs,
+duplicate closes. See `engdocs/design/session-model-unification.md` (Runtime
+Environment) for where `GC_ALIAS`/`GC_TEMPLATE` are defined, and the
+`ga-i1d0tr` architecture decision for the full incident writeup. The
+`${GC_ALIAS:-$GC_TEMPLATE}` fallback form degrades safely to today's
+behavior for sessions where `GC_ALIAS` is unset (pure singleton/named
+templates, where the two values are identical anyway).

+title: Hold and Blocked Label Conventions
+description: The canonical hold/blocked label taxonomy for this project's own bd tracker — which label to use, when to use status or a dependency edge instead, and what happened to the old ad hoc labels.
+---
+
+## Why this exists
+
+Before 2026-07-14 this repo's bd tracker had accumulated at least 8 overlapping
+ad hoc "hold"-family labels with unclear, possibly inconsistent semantics
+(`arch-hold`, `blocked`, `blocked-by-operator`, `blocked-on-external`,
+`blocked-on-upstream`, `blocked-prereq`, `human-hold`/`human`, `on-hold`),
+alongside the one label that already followed the sanctioned convention,
+`hold:mayor`. `ga-tug8ry` audited and consolidated them down to two canonical
+values; `ga-tug8ry.2` migrated every live bead onto the result. This page is
+the durable reference so nobody reinvents another ad hoc hold label — if
+you're about to pause a bead and reach for a new label name, stop and use one
+of the two values below instead.
+
+Full rationale and the live census this decision was based on:
+`bd show ga-tug8ry.1` (the decision) and `bd show ga-tug8ry.2` (the
+migration record, including before/after counts).
+
+## Three orthogonal "not ready" mechanisms
+
+A bead can be "not simply ready to work" for three structurally different
+reasons. Pick the mechanism that matches *why* you're pausing it, not just
+"it's blocked":
+
+| Mechanism | How to set it | Meaning |
+|---|---|---|
+| Dependency edge | `bd dep add <a> <b>` | Bead A cannot start until bd-tracked bead B closes. Gates `bd ready`. Computed from real edges, not a manual claim. |
+| Bead status | `bd update <id> --status blocked` | "I cannot currently proceed," with no further structure about why or who must act. |
+| `hold:<value>` label | `bd set-state <id> hold=<value> --reason "..."` | "I am paused pending a specific actor or condition." Structured, audited (files an event bead), and names the *who*. |
+
+These are orthogonal and combine freely — a bead can be `status=blocked`
+**and** `hold:external` at the same time. Use a dependency edge when the
+blocker is itself a bd bead; use `status=blocked` when nothing more specific
+applies; use `hold:<value>` only when a specific actor or external condition
+is the actual reason you're paused.
+
+## Canonical `hold:<value>` values
+
+Only two values are canonical. Don't introduce a third without a new
+architecture decision — see `ga-tug8ry.1` for the reasoning that narrowed
+the taxonomy to these two.
+
+- **`hold:mayor`** — the required next actor is the mayor. Covers both
+  mayor-initiated pauses and automation-escalated-to-mayor cases; both are
+  the same operational state ("nothing proceeds until the mayor acts") and
+  share one value rather than being split in two.
+- **`hold:external`** — the required next actor or condition is outside this
+  bd instance's control (an external repo's maintainers, an upstream PR
+  merge, etc.). Established by `ga-h7hnpt`.
+
+Set either with the sanctioned command — never with a plain `bd label add`:
+
+```bash
+bd set-state <id> hold=mayor --reason "why, and who/what unblocks it"
+bd set-state <id> hold=external --reason "why, and who/what unblocks it"
+```
+
+`bd set-state` removes any existing label in the `hold:` dimension, adds the
+new one, and files an audit event bead. It does **not** touch `status`,
+`owner`, or `metadata` — update those separately (or add a dependency edge)
+if they also need to change.
+
+## Retired labels
+
+These labels are legacy. If you see one on a live bead, treat it as drift
+worth a bug report, not a pattern to follow.
+
+| Legacy label | Replace with | Notes |
+|---|---|---|
+| `blocked-by-operator` | `hold:mayor` | "Operator" meant the human operator/mayor seat. |
+| `blocked-on-upstream` | `hold:mayor` | Means "next step in our own merge pipeline," not an external repo — despite the name, this is not a `hold:external` synonym. |
+| `human-hold`, bare `human` | `hold:mayor` | Both named the same "next actor is mayor" state as a bare label. Caution: a bare `human` label can also appear alone for an unrelated reason (a human merge/PR action needed) that is not a hold state at all — check the bead's own context before assuming `human` implies a hold. |
+| `blocked-on-external` | `hold:external` | Direct predecessor of `hold:external`; carry forward any `blocker_scope`/`external_blocker`/`external_pr`/`pr`/`repo` metadata unchanged. |
+| `blocked` | none — use native `status=blocked` | Redundant with the bead's own `Status` field; keeping both invites drift between them. |
+| `arch-hold` | none — owned by the `maintainer-pr-review` pack | Not a generic bd hold; it's that pack's own gate, cleared via `gc maintainer-pr-review clear-hold`. It only looked like one of ours because it lacks the `mpr-` prefix its sibling `mpr-human-hold` carries. |
+| `blocked-prereq` | none today; if it recurs, use a dependency edge (prerequisite is a bd bead) or `hold:external` with PR numbers recorded in metadata (prerequisite is bare GitHub PR numbers) | Historical: blocked on specific GitHub PRs merging first, with no corresponding bd bead. |
+| `on-hold` | none — already superseded | Any bead needing this should already carry the canonical `hold:mayor`/`hold:external` in its place. |
+
+**Explicitly out of scope — do not migrate these, they mean something
+different:**
+
+- `mpr-human-hold` and other `mpr-*` labels — owned end-to-end by the
+  `maintainer-pr-review` pack, with its own metadata namespace and its own
+  clearing tool. Not a generic bd hold label.
+- `build-blocker`, `ci-blocker`, `pre-push-blocker`, `push-blocking`,
+  `test-blocker` — a different semantic axis ("pipeline stage X is red
+  because of me"), not "I am waiting on decision-maker Y."
+- `needs-mayor` / `needs-mayor-decision` — a routing/queue-placement label
+  (parallel to `needs-architecture`, `needs-design`, `needs-pm`,
+  `ready-to-build`), not a pause-state label. It may legitimately co-occur
+  with `hold:mayor`.
+
+## This is a data convention, not SDK behavior
+
+Nothing in this page requires or implies special-casing any role name in Go.
+`hold:mayor` and `hold:external` are plain label values in this project's own
+bd data, chosen and enforced by convention — this document, PR review, and
+`bd set-state`'s dimension semantics — not by SDK code. Gas City's "ZERO
+hardcoded roles" invariant is unaffected: nothing under `internal/` or
+`cmd/gc/` branches on the literal label value `hold:mayor` or `hold:external`.

+# Testing Efficiency Operating Corpus
+
+- **Status:** Living operational companion
+- **Checkpoint:** 2026-07-24, after merged PR
+  [#4599](https://github.com/gastownhall/gascity/pull/4599)
+- **Program:** `ga-80po0c`
+- **Audience:** Coordinators, architects, implementers, and reviewers improving
+  Gas City's test architecture
+
+## Purpose and authority
+
+This document captures the operating method used to make Gas City's tests
+faster without weakening their ability to catch regressions. It explains how
+to find a candidate, choose the truthful test edge, design a bounded slice,
+delegate it, review it, merge it, and divide the remaining program among a
+team.
+
+It is deliberately not another testing policy:
+
+1. [`TESTING.md`](../../TESTING.md) is the canonical, normative source for
+   test design, placement, doubles, conformance, timing, flakes, and resource
+   policy. It wins every conflict.
+2. The
+   [testing pyramid audit and hardening plan](testing-pyramid-hardening-plan.md)
+   is the dated audit, rationale, proposed dependency graph, and program
+   backlog. Its counts and task status are historical unless a checked source
+   says otherwise.
+3. This corpus is the operational playbook, evidence catalog, and team
+   handoff. It explains how to execute the policy and plan; it does not amend
+   either one.
+
+Live checked ledgers, manifests, and tests outrank prose about their current
+contents. Do not copy a live ceiling, waiver, owner, or timing status from this
+document into a decision without querying its checked source.
+
+## Mission and non-negotiables
+
+The outcome is developer-visible protected PR feedback at p95 under five
+minutes while preserving or improving defect detection. The normative rules
+for smallest owners, seams, failure edges, asynchronous waits, doubles,
+conformance, E2E admission, flakes, and timing are in
+[`TESTING.md`](../../TESTING.md). This workflow never overrides them.
+
+Speed is a constraint on architecture, not permission to delete confidence.
+A slow test is evidence of a design question: either it owns a real boundary,
+or production logic is trapped behind an unnecessarily expensive boundary.
+
+The clean-architecture test is simple: if a domain rule can be proved only by
+starting a process, changing the working directory, waiting for a timer, or
+opening a database, first look for the missing use-case boundary. The normal
+answer is dependency inversion and a smaller proof, followed by one retained
+adapter or composition proof.
+
+## Working vocabulary
+
+| Term | Meaning in this program |
+|---|---|
+| **Risk sentence** | One sentence stating the condition, observable promise, and regression the proof must catch. |
+| **Assertion owner** | The smallest test that primarily owns one invariant. A higher test may separately own wiring. |
+| **Real-boundary proof** | A focused proof using the real process, protocol, store, filesystem, runtime, browser, or other boundary because that composition is the risk. |
+| **Fast substitute** | A conformant in-memory implementation, strict protocol executable, fake clock, scripted collaborator, or similarly deterministic dependency. |
+| **Invariant map** | The reviewable mapping from every old assertion to its new primary owner and any retained real-boundary proof. |
+| **Slice** | One independently measurable and reviewable architecture change, with one writer and explicit non-goals. |
+| **Council** | Three independent delegated reviews of the same exact staged tree before commit. |
+| **Ratchet** | Checked policy that prevents known resource or architecture debt from growing and lowers when debt is removed. |
+
+## Where the program started
+
+The 2026-07-13 audit found broad coverage but inverted cost and unclear
+ownership. Its point-in-time census reported 1,548 Go test files and 735,331
+lines of test Go. `cmd/gc` alone held 318,018 test lines, produced a 293 MB
+test binary, used about 4.1 GB to compile, and took 55 seconds merely to compile
+in a warm local measurement.
+
+That shape produced five recurring problems:
+
+| Problem | Architectural cause | Correct response |
+|---|---|---|
+| Long package and shard floors | Domain decisions exercised through the `cmd/gc` monolith | Extract cohesive use cases; do not merely split files or add shards. |
+| Slow or flaky asynchronous tests | Sleep and polling substituted for lifecycle signals | Publish or expose completion, readiness, exit, events, barriers, or virtual time. |
+| Repeated process/store/provider startup | A real dependency was used for a non-boundary assertion | Move the branch matrix to a conformant substitute and retain one real wiring proof. |
+| False confidence from fakes | Reusable substitutes did not share production contracts | Repair contract honesty before deleting broad coverage. |
+| Overlapping E2E families | Multiple journeys repeated lower-level behavior | Map assertions, strengthen lower owners, and keep only the unique composition. |
+
+Merged PR [#4193](https://github.com/gastownhall/gascity/pull/4193)
+established the immediate latency baseline: its exact-main run completed in
+4m59s workflow wall time including queueing and 4m15s from runner-policy start
+to `CI / required`. The hardening program exists to make that result
+repeatable through better test and production architecture, not one-time CI
+topology.
+
+## What has shipped
+
+The following are representative milestones, grouped by the reusable pattern
+they established. Timing labels mean:
+
+- **Observed timing:** comparable before/after wall or execution measurements
+  on the same environment/profile.
+- **Observed work:** causal counts such as command roots, builds, writes, or
+  sleeps. These do not by themselves prove a wall-time improvement.
+- **Projected:** a timing effect was extrapolated rather than measured on the
+  claimed layer.
+- **Neutral:** correctness, determinism, or policy improved without a claimed
+  timing improvement. This includes measured “no material timing change”
+  outcomes.
+
+| Pattern | Representative merged work | Evidence at merge | Durable lesson |
+|---|---|---|---|
+| Canonical policy | [#4413](https://github.com/gastownhall/gascity/pull/4413) | **Neutral:** made `TESTING.md` authoritative | Policy belongs in one place; operational docs link to it. |

+| Event-driven in-memory watchers | [#4340](https://github.com/gastownhall/gascity/pull/4340) | **Observed timing:** conformance repetitions improved 6.15x and 9.11x | A generation channel can broadcast a fact without a polling fallback. |
+| Live request correlation | [#4369](https://github.com/gastownhall/gascity/pull/4369) | **Neutral:** removed 15 sleeps; no demonstrated E2E speedup | Events improve determinism and diagnostics even when end-to-end wall time stays flat. |

+| Contract honesty before speed | [#4350](https://github.com/gastownhall/gascity/pull/4350) | **Observed timing:** suite grew 58.63s to 62.80s while archive semantics became executable | A truthful contract may cost time. Quality work is not required to manufacture a speed claim. |
+| Strict protocol doubles | [#4344](https://github.com/gastownhall/gascity/pull/4344) | **Observed timing:** Docker CI coverage fell from 218s to 48s while retaining all 35 real-container assertions in one boundary proof | Use a strict executable for argument/protocol branches and one real platform composition. |

+| Deterministic timing planner | [#4400](https://github.com/gastownhall/gascity/pull/4400) | **Neutral:** added pure p75/p95 planning in dry-run authority | A planner is measurement infrastructure until activation is explicitly checked; do not claim adaptive sharding is live. |

+
+If the base moves after council:
+rebase → restage → recompute tree/patch ID → repeat all three reviews
+```
+
+The architect completes the design before delegating implementation. The next
+optimization is not started while the current one is awaiting correctness
+review, CI repair, or merge unless it has disjoint ownership and the
+coordinator explicitly assigns a separate lane.
+
+## How to select a candidate
+
+Start from evidence, not intuition. A candidate needs at least one of:
+
+- a measured latency floor;
+- deterministic elapsed-time waiting;
+- first-attempt flakiness or weak timeout diagnostics;
+- repeated real process, listener, database, provider, or filesystem startup;
+- duplicate assertions across high-level journeys;
+- repeated command-root, build, discovery, or persistence work; or
+- a policy blind spot that allows resource debt to grow.
+
+Prioritize in this order:
+
+1. Authored wall-time floors and flaky polling.
+2. Real dependencies used for assertions that do not concern that boundary.
+3. Duplicate E2E or acceptance journeys.
+4. Cartesian command, provider, and error matrices.
+5. Repeated persistence, compilation, and discovery.
+6. Cohesive production extraction that reduces package compile/global-state
+   tax.
+7. Shard balancing after the runnable work is truthful.
+
+Then use this decision tree:
+
+```text
+Can the exact regression risk be stated in one sentence?
+├─ no  → inventory assertions before editing
+└─ yes
+   ├─ does a smaller existing proof already own every assertion?
+   │  ├─ yes, no unique composition → consolidate or delete with an invariant map
+   │  ├─ yes, unique composition    → retain one reduced real-boundary proof
+   │  └─ no                         → create or strengthen the smaller owner
+   │
+   ├─ what makes the proof expensive?
+   │  ├─ sleep, timer, backoff      → fake clock or testing/synctest
+   │  ├─ async completion           → event, channel, exit, readiness, or barrier
+   │  ├─ persistence                → conformant memory owner + one real wiring proof
+   │  ├─ process/provider startup   → strict/scripted double + one lifecycle proof
+   │  ├─ command matrix             → pure decision table + minimal compositions
+   │  ├─ repeated discovery/build   → checked manifest or shared invocation
+   │  └─ package compile tax        → extract cohesive production logic
+   │
+   └─ can one writer measure and review the slice independently?
+      ├─ no  → split it
+      └─ yes → design, delegate, and implement
+```
+
+Stop rather than optimize when:
+
+- the candidate is slow only because its real boundary is the exact risk and no
+  duplicate work is present;
+- no trustworthy lower owner or conformant substitute exists yet;
+- the proposed seam is broader than the consumer's need;
+- the change would mix several behaviors or file-ownership domains;
+- comparable measurement is unavailable and no deterministic cost can be
+  counted; or
+- the only plan is to relabel, skip, retry, or move the test to another lane.
+
+## Policy checkpoints for the design
+
+Do not restate test policy in a task. Link the canonical rule and record the
+decision it produced:
+
+| Decision to record | Canonical source | Slice artifact |
+|---|---|---|
+| Smallest truthful owner | [Authoring rule](../../TESTING.md#the-authoring-rule-one-risk-one-smallest-owning-proof) | Named primary owner and unique higher-level risk |
+| Production seam | [Fast-proof design](../../TESTING.md#design-production-code-for-fast-proofs) | Existing port, function injection, private bundle, or justified narrow port |
+| Failure classes | [Meaningful failure edges](../../TESTING.md#choose-meaningful-failure-edges-not-cartesian-products) | Applicable equivalence classes and intentionally omitted combinations |
+| Asynchronous wake | [Wait for facts](../../TESTING.md#asynchronous-tests-wait-for-facts-not-elapsed-time) | Signal/correlation identity, durable reread, and timeout diagnostics |
+| Substitute honesty | [Doubles and conformance](../../TESTING.md#test-doubles-and-conformance-are-one-contract) | Applicable shared suite and exact production construction |
+| Real journey admission | [E2E portfolio](../../TESTING.md#keep-the-critical-end-to-end-portfolio-deliberately-small) | Unique composition risk, lower owners, lane, budget, and owner |
+| Timing claim | [Timing objectives](../../TESTING.md#timing-objectives-and-resource-ratchets) | Comparable commands, environment, layer, samples, and claim class |
+
+## Design the slice before delegation
+
+Every implementation starts with a design brief containing:
+
+1. **Problem and measured cost.** Identify the exact test, package, shard, or
+   policy gap and the evidence.
+2. **Risk sentence.** Name the condition, observable outcome, and escaping
+   regression.
+3. **Current assertion owners.** Inventory what each current proof actually
+   asserts.
+4. **Smallest new owner.** Name the unit, conformance, coordination,
+   testscript, integration, or E2E owner.
+5. **Seam decision.** State the selected seam and why a broader abstraction is
+   unjustified.
+6. **Invariant map.** Map every moved or removed assertion.
+7. **Retained real boundary.** Name the singular composition proof and what
+   only it can catch.
+8. **TDD sequence.** Define the RED, GREEN, refactor/removal, and mutation or
+   negative proof.
+9. **Measurement.** Name exact base/candidate commands and causal counters.
+10. **Scope.** List expected files, explicit non-goals, and stop conditions.
+
+Use this risk form:
+
+```markdown
+Risk: If <condition>, <observable contract> must <outcome>; otherwise
+<specific regression> escapes.
+```
+
+Use this invariant map:
+
+```markdown
+| Invariant | Old owner | New primary owner | Retained real boundary | Failure evidence |
+|---|---|---|---|---|
+| ... | ... | ... | ... | RED, mutation, or negative fixture |
+```
+
+One primary owner does not forbid composition coverage. It prevents the
+composition test from repeating the lower owner's branch matrix.
+
+### Design stop conditions
+
+The implementer stops and returns to the architect when:
+
+- the intended RED fails for a different reason;
+- production semantics must change in a behavior-neutral slice;
+- a second public abstraction appears necessary;
+- expected files or ownership domains expand materially;
+- another writer is touching the same files;
+- the retained real-boundary proof cannot be named;
+- the proposed double cannot share the production contract; or
+- measurements contradict the assumed bottleneck.
+
+## Correctness evidence
+
+Follow the canonical
+[RED, GREEN, refactor, measure loop](../../TESTING.md#red-green-refactor-measure).
+The handoff must retain the failing output or mutation, the minimal passing
+change, the invariant map, and results for the primary and real-boundary
+owners.
+
+For a behavior-neutral migration, acceptable evidence includes a missing-seam
+compile failure, a failing architecture/resource ratchet, a deliberate
+mutation caught by the new owner, a negative policy fixture, or
+characterization of stable public behavior. Do not manufacture a meaningless
+semantic failure.
+
+State neutrality precisely. A policy-scanner slice, for example, may be
+production/runtime and test-execution neutral while intentionally changing
+policy enforcement.
+
+## Measurement and claim discipline
+
+Measure the thing the slice claims to improve:
+
+| Layer | What it answers |
+|---|---|
+| Test body | Did deterministic work or waiting leave this test? |
+| Package wall time | Did compile, link, setup, and test execution improve together? |
+| Owning shard | Did the runnable unit improve in its normal peer set? |
+| Workflow/job wall | Did setup, queueing, dependencies, and runner variance preserve the gain? |
+| Causal work | Did process starts, writes, command roots, builds, listeners, or retries actually decline? |
+
+Capture exact SHAs, commands, environment/profile, cache condition, sample
+count, and layer according to the
+[timing policy](../../TESTING.md#timing-objectives-and-resource-ratchets).
+Use an isolated cache for cold builds; never clear the shared build cache.
+
+If variance dominates, report “no measurable regression” or “deterministic
+wait removed,” not a speedup. PR #4528 is the canonical warning: test execution
+dropped about 67 seconds while total PR wall rose because cold setup changed.
+PR #4599 correctly reported flat scanner timing as no measurable regression.
+
+## Delegated implementation protocol
+
+Parallelism is used asymmetrically:
+
+- research and candidate audits may run in parallel;
+- one architect owns the design and invariant map;
+- one implementer is the sole writer for one slice; and
+- independent reviewers inspect the finished staged tree in parallel.
+
+Do not assign multiple implementers to overlapping production or ledger files.
+When two slices touch the same construction path, fake, manifest, generated
+table, or `TESTING.md` section, serialize them or explicitly stack them.
+
+The implementation assignment must include:
+
+- bead, exact base SHA, branch, and isolated worktree;
+- statement that the delegate is the sole writer for the slice;
+- risk sentence and invariant map;
+- chosen test edge, seam, and retained real-boundary owner;
+- expected files and explicit non-goals;
+- required RED/GREEN or mutation evidence;
+- baseline and candidate commands;
+- focused, conformance, race, shard, ledger, and docs checks;
+- prohibition on broad interfaces, global hooks, hidden polling, retries, and
+  unrelated cleanup;
+- instruction to stage but not commit or push before council; and
+- the stop conditions above.
+
+### Copyable implementation assignment
+

+
+## Exact-tree review council
+
+Before commit, delegate three independent, read-only review tasks. The default
+council uses three capable SOL review tasks through ordinary task delegation;
+it does not require a separate workflow product.
+
+All reviewers receive:
+
+- the same base SHA;
+- the same isolated worktree path and expected `HEAD`;
+- the same staged tree hash from `git write-tree`;
+- the same stable patch ID;
+- the design brief and invariant map;
+- measurements and exact commands; and
+- the instruction to return `APPROVE` or severity-ranked findings.
+
+The three lanes are:
+
+| Lane | Required review |
+|---|---|
+| Semantic correctness | Read tests first; validate every moved invariant, failure edge, behavior-neutral claim, and retained real-boundary proof. |
+| Testing architecture and performance | Validate smallest-owner placement, seam size, double conformance, event-versus-polling choice, E2E admission, and every timing claim. Ensure work was removed rather than moved. |
+| Repository and policy integrity | Validate checked ledgers/manifests, generated tables, docs, build tags, CI placement, maintainability, upstream alignment, and bounded scanner/runtime cost. |
+
+For resource-policy changes, the repository lane independently checks
+all-source, untagged-source, and effective Small inventories. PR #4599 showed
+why: the council caught newly landed tagged helper calls that an
+untagged-only audit would have missed.
+
+Any content or base change invalidates the exact-tree approval. Restage,
+compute a new tree and patch ID, and rerun all three reviews. The committed
+tree must equal the approved tree.
+
+### Copyable council prompt
+
+```markdown
+Read-only review in `<worktree>`.
+Expected HEAD/base: `<base-sha>`
+Expected staged tree: `<tree-hash>`
+Expected stable patch ID: `<patch-id>`
+Do not edit files or tracker state.
+
+Verify before review:
+
+git rev-parse HEAD
+git write-tree
+git diff --cached | git patch-id --stable
+git diff --quiet
+test -z "$(git ls-files --others --exclude-standard)"
+
+Design brief: ...
+Invariant map: ...
+Evidence: ...
+
+Review lane: `<semantic | architecture/performance | repository/policy>`.
+
+Inspect the tests before implementation. Verify the stated behavior,
+ownership, exclusions, and evidence rather than trusting the PR narrative.
+Return either:
+
+APPROVE — with the tree hash and checks performed
+
+or severity-ranked findings:
+- Critical: ...
+- Important: ...
+- Suggestion: ...
+```
+
+## Commit, PR, and merge shepherding
+
+Use this order:
+
+1. Start from current `origin/main` in an isolated worktree.
+2. Finish the slice, fetch `origin/main`, and refresh the slice onto that base
+   before freezing it. If the base moved, rerun affected checks and inspect
+   the complete candidate diff; recompute rather than hand-resolve generated
+   ledgers.
+3. Stage only the slice's files. Manually run the repository pre-commit hook
+   and relevant focused checks,
+   then restage if a tool changed anything.
+4. Record `git write-tree` and run the three-lane council.
+5. Address findings and repeat all three lanes for every content or base
+   change.
+6. Commit the approved tree and verify the commit tree matches it.
+7. Push, open a focused PR, enable squash auto-merge only after review and
+   verification are complete, and watch required CI on the current SHA.
+8. If another rebase becomes necessary, recompute the full tree and patch ID,
+   inspect `git range-diff`, rerun affected checks, and repeat all three
+   council lanes before updating the PR. A cleanly applied patch still has a
+   new full-tree context.
+9. Treat deterministic test failures as product or test defects. Diagnose and
+    fix them; never rerun them into green.
+10. Verify the merge SHA on `main`, close the bead, remove the clean worktree
+    and branch, and confirm nothing remains unpushed.
+
+If a local gate fails on unchanged base code, reproduce it in a detached
+worktree at the exact base SHA. Record both commands and outputs. Bypassing a
+hook is exceptional: it requires exact base-failure evidence, no affected
+failure in the patch, and successful required remote CI. Keep the base defect
+separate from the optimization.

+
+## Failure handling
+
+| Situation | Response |
+|---|---|
+| Focused test fails deterministically | Stop and repair or revise the design. Do not retry for a green sample. |
+| Result changes with no code change | Investigate test/infra reliability and attach evidence; one owner remains until resolved. |
+| Base branch fails the same gate | Reproduce at exact base SHA and separate the base defect from the slice. |
+| Measurement is noisy | Interleave samples, count causal work, and narrow the claim. |
+| Rebase changes policy inventory | Recompute from source and rerun policy review. |
+| New main invalidates the seam or owner | Return to design; do not force the old patch through. |
+| CI finds a missing assertion owner | Add the smallest owner first, then decide whether the high-level reproduction is unique. |
+| Contributor branch or worktree collides | Stop one writer, preserve both diffs, and reassign explicit file ownership. |
+
+## Dividing the program safely
+
+The coordinator owns dependency ordering, not implementation. Each lane owns a
+cohesive boundary and may contain only one active writer per overlapping file
+set.
+
+The following is the verified 2026-07-24 allocation snapshot. Query GitHub,
+`gc bd`, and current checked ledgers before reusing it. It intentionally
+excludes documentation-only bead `ga-80po0c.28`.
+
+| Lane | Current work | Parallelism rule |
+|---|---|---|---|
+| Resource critical path | `ga-80po0c.2.2.4`, then `.2.2.5` | Strictly serial: both own the same census, ledger, and policy files |
+| Timing and race | Residual `ga-80po0c.4`, then `.5` | Independent from scanner implementation; serialize workflow and `TESTING.md` integration |
+| Runtime conformance | Remaining `ga-80po0c.3` provider waivers | Package-local proofs may run in parallel; one coordinator serializes provider-ledger and docs changes |
+| Docker | Remaining `ga-80po0c.23` real-matrix consolidation | Independent package/design work; land before E1 if possible to avoid immediate manifest churn |
+| E1 inventory | Read-only Large-test/provider census for `ga-80po0c.6` | Research may run now; implementation waits for `.2.2.5` and parent completion |
+| Tracker reconciliation | Leaves with a verified merge SHA but stale status | Administrative only; do not close aggregate parents merely because some children shipped |
+
+The known listener-policy chain at this checkpoint is:
+
+```text
+ga-80po0c.2.2.3 / PR #4599
+    → ga-80po0c.2.2.4
+        → ga-80po0c.2.2.5
+            → E1 / ga-80po0c.6
+```
+
+The resource critical path exclusively owns these files while active:
+
+- `internal/testpolicy/resourcecensus/census.go`
+- `internal/testpolicy/resourcecensus/census_test.go`
+- `internal/testpolicy/resourcecensus/hermetic.go`
+- `internal/testpolicy/resourcecensus/hermetic_test.go`
+- `test/test-resources.toml`
+- `TESTING.md`
+
+Treat `TESTING.md` as a single-writer integration file. Other lanes may prepare
+package-local changes concurrently, but canonical-policy updates land
+serially.
+
+The old `.2.2.4` branch `test/resource-listener-indirect` at `608299f5` was 216
+commits behind this checkpoint and included already-merged predecessor
+commits. It is design and test evidence only. Reconstruct its semantic delta on
+current `main`; do not merge or cherry-pick the stack wholesale.
+
+The hierarchy audit also found four other leaves still recorded
+`in_progress` despite authoritative merged code:
+
+| Bead | Merged evidence |
+|---|---|
+| `ga-80po0c.22` | [PR #4340](https://github.com/gastownhall/gascity/pull/4340), `afe9d3a3` |
+| `ga-80po0c.26` | [PR #4414](https://github.com/gastownhall/gascity/pull/4414), `38910235` |
+| `ga-80po0c.27` | [PR #4417](https://github.com/gastownhall/gascity/pull/4417), `6f0aa5c8` |
+| `ga-80po0c.3.3` | [PR #4407](https://github.com/gastownhall/gascity/pull/4407), `e3439b29` |
+
+Reconcile those leaves before using ready-queue output as a program plan.
+`ga-80po0c.23`, `.3`, `.4`, `.2`, `.2.2`, `.2.2.4`, `.2.2.5`, `.5`, `.6`,
+and the root remained legitimately live at the audit checkpoint. Their status
+is a snapshot, not policy.
+
+Snapshot provenance is a read-only 2026-07-24 hierarchy/dependency audit of
+`ga-80po0c`, reconciled against merged PR SHAs and recorded in
+`ga-80po0c.28` notes. The merge evidence establishes code state; future
+coordinators must query the tracker for current administrative state.
+
+Do not start a downstream child merely because the predecessor's code appears
+present. Verify its merge SHA, close or reconcile stale tracker state, reread
+the child against current `main`, and reserve its shared policy files.
+
+### Coordinator protocol
+
+1. Query GitHub and the bead graph before assigning work.
+2. Treat a merged GitHub SHA as authoritative for code state; tracker status
+   may be stale and must be reconciled before another worker is assigned.
+3. Use `gc bd` for scoped tracker operations rather than ambient raw `bd`.
+4. Select one candidate through the decision tree and write its design brief.
+5. Reserve files and name the sole implementation writer.
+6. Delegate independent research in parallel only where it cannot mutate the
+   slice.
+7. Hold the next dependent slice until merge, bead closure, and cleanup.
+8. Keep unrelated lanes parallel only when their production, test-support,
+   ledger, generated, and documentation ownership is disjoint.

+## Case studies
+
+### 1. Split-store wait: move policy, keep composition
+
+PRs [#4309](https://github.com/gastownhall/gascity/pull/4309) and
+[#4333](https://github.com/gastownhall/gascity/pull/4333) moved readiness and
+registration decisions onto injected stores, identity, clock, and poke seams.
+The representative package result fell from 82.28s to 1.94s, and a later
+composition fell from 54.61s to 0.42s. The work did not erase the risk that
+CLI/config/file-store and managed-provider pieces compose: one named real
+split-store proof and the managed hard-kill/port-rebind proof remained.
+
+Pattern: branch matrices belong to direct use cases; store selection and
+provider recovery retain focused composition owners.
+
+### 2. Event-driven waits: determinism is a first-class result
+
+PR [#4340](https://github.com/gastownhall/gascity/pull/4340) replaced an
+in-memory watcher polling fallback with broadcast generation channels and
+produced 6.15x–9.11x improvements in repeated contract runs. PR
+[#4369](https://github.com/gastownhall/gascity/pull/4369) removed 15 sleeps
+from live API contracts by capturing SSE cursors and correlating request IDs,
+but correctly claimed no demonstrated end-to-end speedup.
+
+Pattern: subscribe before the action, wake on identity-correlated facts, and
+reread durable state. Determinism and diagnostics are valid outcomes even when
+wall time is flat.
+
+### 3. Exact constructor conformance: remove duplication after truth
+
+PRs [#4326](https://github.com/gastownhall/gascity/pull/4326),
+[#4403](https://github.com/gastownhall/gascity/pull/4403),
+[#4404](https://github.com/gastownhall/gascity/pull/4404), and
+[#4407](https://github.com/gastownhall/gascity/pull/4407) established one
+shared conformance run through each exact production composition rather than
+duplicating raw implementation and wrapper suites. PR
+[#4350](https://github.com/gastownhall/gascity/pull/4350) is the guardrail:
+mail contract honesty added about 4.17 seconds, and that cost was accepted
+before later consolidation.
+
+Pattern: prove the substitute and actual constructor first. Speed obtained from
+an untruthful double is negative progress.
+
+### 4. E2E consolidation: delete journeys, not invariants
+
+PR [#4426](https://github.com/gastownhall/gascity/pull/4426) reduced 34 mail
+commands to a five-command bidirectional journey after focused owners covered
+the command semantics. PRs
+[#4502](https://github.com/gastownhall/gascity/pull/4502),
+[#4510](https://github.com/gastownhall/gascity/pull/4510),
+[#4528](https://github.com/gastownhall/gascity/pull/4528), and
+[#4564](https://github.com/gastownhall/gascity/pull/4564) applied the same
+assertion-ownership method to close, mail, real-city, and lifecycle families.
+
+Pattern: inventory every assertion, strengthen the lower owner where needed,
+retain the unique composition, then remove the duplicate journey.
+
+### 5. Compile/discovery work: execute once, then ratchet
+
+PRs [#4339](https://github.com/gastownhall/gascity/pull/4339),
+[#4505](https://github.com/gastownhall/gascity/pull/4505),
+[#4515](https://github.com/gastownhall/gascity/pull/4515),
+[#4518](https://github.com/gastownhall/gascity/pull/4518), and
+[#4568](https://github.com/gastownhall/gascity/pull/4568) removed repeated
+static work, nested builds, runtime discovery, and duplicate Go invocations.
+PRs [#4571](https://github.com/gastownhall/gascity/pull/4571),
+[#4573](https://github.com/gastownhall/gascity/pull/4573), and
+[#4599](https://github.com/gastownhall/gascity/pull/4599) then made resource
+ownership harder to regress.
+
+Pattern: replace repeated discovery with checked identity/manifest policy,
+share build work, and keep the guard bounded. Sharding cannot remove a giant
+package's compile tax.
+
+## Failure patterns observed
+
+The detailed prohibitions live in `TESTING.md`. These program-level mistakes
+caused the most churn:
+
+- optimizing a file without first naming its assertion owners;
+- moving or deleting a journey before lower owners and the retained boundary
+  were explicit;
+- using a real dependency for a decision that did not concern that boundary;
+- hiding elapsed-time waiting inside a generic helper;
+- trusting an uncontracted fake or an all-skipped conformance run;
+- adding shards while preserving the same package compile floor;
+- reporting a test-body gain as a package, shard, or workflow gain;
+- retrying a deterministic failure instead of diagnosing it;
+- assigning overlapping writers or reviewing different trees; and
+- replaying stale branches or resolving checked ledgers without recomputing
+  current source evidence.
+
+## Checkpoint and restart procedure
+
+At the 2026-07-24 checkpoint:
+
+- PR [#4599](https://github.com/gastownhall/gascity/pull/4599) merged as
+  `97e1cb5272a41f21efd7e137a143c35cf34cc713`; 51 executed checks passed
+  and 28 path-gated checks skipped.
+- `ga-80po0c.2.2.3` was reconciled closed against that merge.
+- The listener-helper ratchet recorded 38 calls in 13 untagged files, 20 calls
+  in 10 tagged files, and 58 calls in 23 files across all source. These are a
+  dated evidence snapshot; query the live census for current values.
+- No next optimization was started. This corpus is documentation-only work
+  performed during that pause.
+
+To restart the program:
+
+1. fetch current `origin/main`;
+2. reconcile merged PRs with the `ga-80po0c` graph;
+3. verify predecessor closure and current checked inventories;
+4. reread the next task against current production and tests;
+5. run a fresh candidate/design audit rather than copying an old patch; and
+6. assign one implementation writer only after the design brief is complete.

 **Dependencies:** P0.2 timing output. **Estimate:** medium.
 
+#### P0.6 — Scope ordinary-PR static work without weakening full runs
+
+**Change:** Let only a validated effective `pull_request` synthetic merge run
+impact-scoped lint and formatting. Validate the default `GITHUB_SHA` checkout
+against the event's exact base SHA with both merge parents present; never infer
+the base from a mutable ref or a merge-base calculation. Every effective
+non-PR or unknown event, invalid checkout/base, and protected static-policy
+change fails safe to full lint, full formatting, and standalone vet. Reusable
+workflows inherit the caller event and receive no exemption of their own: an
+effective `pull_request` may qualify only after the same validation, while the
+current RC `workflow_dispatch` remains full.
+
+The changed lint scope contains packages affected by added, modified, deleted,
+or moved Go-tool build inputs and packages owning changed embedded files, plus
+all transitive reverse dependents. Build inputs include Go, assembly,
+cgo/C/C++/Objective-C, header, Fortran, SWIG, and syso files. Embed ownership
+comes from the canonical package records and their production, internal-test,
+and external-test resolved embed inventories in one `go list -test -json ./...`
+graph. Multiple owners are retained. The reverse-dependency closure preserves
+analyzer-fact consumers that did not change textually, including test-only
+importers. An incomplete package graph, a deleted required embed input, or a
+deletion beneath a package with neither a current embed owner nor a current
+direct package owner fails safe to full-repository lint before native-input
+shortcuts. Changed formatting receives only
+exact existing regular, non-symlink `.go` paths, with NUL-safe handling for
+spaces and no empty formatter invocation. Keep `lint-changed` as the smaller
+local/pre-commit target; the PR workflow uses the distinct conservative
+`lint-affected` target. That target runs configured golangci, including its
+`govet` copy, and the Go tool's exact vet over the same closure. The bounded
+duplicate preserves both diagnostic surfaces without repeating either across
+the whole repository. Any selection failure runs both configured lint and
+standalone vet over `./...`; fallback never disables a configured linter.
+Native include and linker inputs can have recognized or arbitrary names and may
+live outside the consuming package, so every changed path selects every package
+with native Go-tool sources plus its reverse dependents.
+
+Protected full-scope paths are the Go module/workspace files,
+every root `.golangci.*` configuration, `Makefile`, workflow/action definitions,
+hooks, vendored code,
+`scripts/cipolicy/**`, `scripts/ci-static-scope`, and
+`scripts/ci-static-select`. Pushes to `main`, schedules, dispatches (including
+the current reusable RC caller), and any unrecognized event also stay full.
+
+**Acceptance:** The workflow runs `lint-affected` and
+`fmt-check-changed` only when the classifier emits `changed`. It uses
+`scope != 'changed'`, rather than equality with a second expected value, for
+full lint, full format, and standalone vet so a missing output cannot skip
+them. Golangci enables `govet` explicitly in both scopes, and affected lint
+invokes standalone vet over the identical package arguments. Every selection
+fallback and full-scope run retains configured golangci plus standalone
+full-repository vet.
+
+**Verification:** Synthetic-repository contracts cover a valid PR merge,
+wrong/missing base, non-merge checkout, every non-PR/unknown event, protected
+paths, changed/deleted/moved Go files, assembly and other recognized Go-tool
+build inputs, arbitrary native include fragments, recognized shared headers,
+and a deleted recognized glob member before native fallback,
+production/internal-test/external-test embedded assets, multiple
+embed owners, a deleted required input and deleted glob member's full-scope
+fallback, unrelated non-build/non-embedded no-op diffs, filenames containing
+spaces, transitive and test-only reverse dependents, a generated
+reverse-dependent diagnostic, and a broken package graph's full-lint fallback.
+Workflow policy tests bind the classifier inputs, exact conditions, checkout
+depth, commands, and explicit `govet` configuration. `make test-ci-policy`
+always runs the four focused static-policy Go contracts, and a self-binding
+contract proves that the Make target cannot silently drop that suite.
+
+**Owner/status:** `ga-80po0c.21`; active implementation slice. The measured
+baseline is PR #4336 Actions run
+[29483623514](https://github.com/gastownhall/gascity/actions/runs/29483623514):
+the static job took 257 seconds, including 120 seconds of full lint, 19 seconds
+of full formatting, and 13 seconds of standalone vet. Qualifying ordinary PRs
+therefore remove 152 seconds of broad static work from the critical path before
+paying the smaller affected-lint/affected-vet/changed-format replacement cost.
+The 61-second native-dependency guard and all other static guards remain. These
+are a current implementation baseline and expected gross saving; they do not
+rewrite the historical #4193 measurements above.

-# gc.active_work_bead — per-step attribution for usage facts (v0)
-
-> Council-reviewed (2026-06-24). Decision 1 = store the work bead's bare `gc.step_id`
-> (unanimous). Decision 2 = clear-on-terminal (majority). The compute read site is cut.
-
-## Problem
-
-Usage facts (`internal/usage`) and the spend rows derived from them carry `RunID`
-and `SessionID`, but **`StepID` is always empty**. The usage record sites only have
-the **session bead** in scope, not the **work bead** the session is executing. So a
-run's cost cannot be broken down per step.
-
-The events plane already carries `step_id`: a `bead.created`/`bead.closed` event reads
-its **subject bead's own `gc.step_id`**. That works because the events record site
-*is* the work bead. The usage record site is the session, so it needs a pointer FROM
-the session TO the work it is running.
-
-## The step identity (corrected; load-bearing)
-
-`gc.step_id` (`beadmeta.StepIDMetadataKey`) is the **bare logical formula step id**
-(e.g. `mol.finalize`), written by the control plane onto a work bead. It is
-**distinct from the bead's runtime `bead.ID`**, which is namespaced per attempt/scope
-(e.g. `mol.finalize.attempt.1`): `control.go:602-605/686-690` set `gc.step_id` to the
-bare `child.ID`/`control.ID` onto a bead whose ID is `attemptPrefix + "." + child.ID`;
-`ralph.go` sets `gc.step_id = step.ID` while the iteration bead id is
-`step.ID + ".iteration.N"`; `molecule.go:1380` builds `index[stepID] = bead.ID`,
-proving the two differ. Non-formula beads (ad-hoc, orders, manual) carry **no**
-`gc.step_id`.
-
-So the step_id that JOINS cross-plane is the **bare `gc.step_id`** — the events plane
-already uses it, and the cost plane must use the same value. Storing `bead.ID` would
-never join with events. **Decision 1 (locked, unanimous): the pointer holds the work
-bead's `gc.step_id`** (empty when the bead has none).
-
-## Goal
-
-Introduce `gc.active_work_bead` on the **session bead**: write the current work bead's
-`gc.step_id` at the claim transition, read it at the model-usage record site to
-populate `usage.Fact.StepID`. Mirrors `gc.current_run_id` (`cmd/gc/cmd_hook_claim.go`).
-Unblocks per-step cost for **formula/molecule runs** (the dominant attributed path);
-ad-hoc/manual work correctly rolls up at run level with empty StepID, matching events.
-
-## Mechanism
-
-### Key
-`internal/beadmeta/keys.go`: `ActiveWorkBeadMetadataKey = "gc.active_work_bead"` +
-add to `KnownMetadataKeys`.
-
-### Write — FOLDED into the run-id write (one atomic Update, same bead)
-`cmd/gc/cmd_hook_claim.go` `recordHookClaimRunID` already writes `gc.current_run_id`
-on the session bead at claim. **Fold** the step write into the SAME `store.Update`:
-derive `stepID = bead.Metadata[StepIDMetadataKey]` from the SAME just-claimed `bead`
-that yields `runID`, and write `{gc.current_run_id: runID, gc.active_work_bead: stepID}`
-in one update. This (a) halves the bd calls + `bead.updated` events per claim, and
-(b) locks the (run, step) tuple — the step is guaranteed to belong to the run stamped
-in the same claim. **Unconditional per claim** (a current-pointer must follow a reused
-pool session), including writing an EMPTY step (clearing a prior step when the new
-work is non-formula).
-
-### Read — model facts only (compute read CUT)
-`internal/worker/invocation_telemetry.go modelUsageFact`: read
-`bead.Metadata[ActiveWorkBeadMetadataKey]` → `Fact.StepID`, from the SAME session-bead
-snapshot `b` already used for `ResolveRunID`, so StepID and RunID never come from two
-reads. Nil-map read returns `""` (Go semantics) — safe, like the existing
-`b.Metadata["provider_kind"]` read.
-
-The compute emitter does **not** read it: `emitComputeFactForBead` fires at the
-session's terminal/sleep transition where the pointer is definitionally stale, and v0
-compute facts are omitted from spend anyway.
-
-### Clear — at the terminal/sleep transition (Decision 2, locked majority)
-`cmd/gc/usage_compute.go` already does `store.SetMetadata` on the session bead at every
-terminal pass. Clear `gc.active_work_bead` there (write `""`), so an idle / manual-chat
-invocation after work ends and before the next claim resolves `StepID=""` (run/session
-level) rather than the last step's id.
-
-## Honest limits (NOT a "rare race")
-- **Stale-on-idle is routine, not rare** — the model read fires on EVERY prompt op
-  (incl. idle/manual-chat), and reused pool/canonical sessions are the norm. The
-  terminal clear (above) is what bounds it; it is REQUIRED before the per-step
-  consumer (#51) ships, not deferred.
-- **Read-record non-atomicity** (genuinely narrow, accepted, matches
-  `gc.current_run_id`): a second claim between the transcript-tail read and the fact
-  record can stamp the new step. Bounded; both pointers read from one snapshot keep
-  StepID under the matching RunID.
-
-## Seam coverage (gc hook --claim is NOT universal)
-Work-starts the claim hook does NOT cover, where `gc.active_work_bead` is empty/stale:
-manual chat / no work bead (→ empty StepID); API-server fresh-handle turns;
-`RuntimeHandle` prompt ops (out of scope per `recordInvocationTelemetry`). **Empty
-StepID for these is CORRECT** — non-attribution, identical to the events plane's empty
-step_id for the same work. The only mis-attribution case is the pooled-session idle
-window, which the terminal clear addresses.
-
-## Test plan (TDD)
-- `beadmeta`: the new key is in `KnownMetadataKeys`.
-- claim hook: one `store.Update` writes BOTH `gc.current_run_id` AND
-  `gc.active_work_bead` on the session bead; the step value = the work bead's
-  `gc.step_id` — with a fixture where **`gc.step_id != bead.ID`** so a `bead.ID`
-  regression can't pass; `ResolveRunID(workbead)` equals the stamped run id (tuple
-  consistency); empty `GC_SESSION_ID` → skip; store error → best-effort (no panic);
-  a non-formula bead (no `gc.step_id`) writes an empty step (clears any prior).
-- `modelUsageFact`: reads the session bead's `gc.active_work_bead` → `Fact.StepID`,
-  distinct from RunID/SessionID; empty when absent.
-- compute terminal: clears `gc.active_work_bead` on the session bead.
-
-## Scope
-gc-side: the key; the folded write at claim; the model read; the terminal clear. OUT
-of scope (separate tasks): the metered-path proxy `X-Gc-Step-Id` stamp; the dashboard
-per-step rollup; the events-ingest `city_events.step_id` consumer.

 path only heals a session that died, never a live-but-idle slot, and activity
 reporting lets the controller see such a slot without ever waking it to claim.
 
-## Open follow-up: widen the trigger key to unassigned pool-routed beads
-
-The backstop keys on the slot's own `gc.trigger_bead_id`. That value is stamped
-only when the desired-state builder binds a specific bead to the slot — the
-`resume` and `wake-known-identity` tiers, both of which act on work that already
-carries an assignee (`cmd/gc/pool_desired_state.go`). A bead slung to the pool
-**after** the slot went idle and left **unassigned** (`gc.routed_to = <pool>`,
-status `open`, no assignee) never stamps `trigger_bead_id`, so it is invisible
-to the backstop: `triggerID == ""` short-circuits the loop.
-
-Result: the un-gate closes the bound-slot case (the reconciler handed this slot
-a specific bead, but its submit-CR was swallowed or it survived a `gc restart`
-without a re-Start). The scale-from-zero-style case — an unclaimed pool bead
-waiting for any warm slot to notice it — is still not woken on tmux.
-
-### Sketch of the fix
-
-For each running pool slot with an empty `trigger_bead_id`, look for a bead
-where `gc.routed_to` resolves to the slot's template, status is `open`, and the
-assignee is empty; past the observe grace, nudge the slot to run its claim hook.
-
-Constraints to preserve the churn-free property:
-
-- Keep the persisted `observe → nudge → backoff → give-up` marker, but key it on
-  the candidate bead id (or the slot when no single candidate dominates) so a
-  restart cannot replay it.
-- The unclaimed pool bead may not be present in the reconciler's
-  `AssignedWorkBeads` snapshot (that slice is assignment-oriented). The widened
-  path needs a source of open+routed+unassigned pool beads; confirm which
-  snapshot already carries them before adding a new read to the hot path.
-- Multiple idle slots seeing one unclaimed bead will each nudge. That is bounded
-  by the grace/backoff/attempt caps and self-limits the instant the first slot
-  claims (the bead flips to `in_progress`), but measure it before shipping.
-
-This is deliberately left for its own PR: it changes what the backstop reads,
-not just when it runs, and the churn analysis is the load-bearing part.
+## Resolved follow-up: include ready unassigned pool-routed triggers
+
+The backstop still keys on the slot's own `gc.trigger_bead_id`. Desired-state
+now carries the concrete ready, routed, unassigned beads selected by the
+default pool-demand probe alongside the assigned-work snapshot. The reconcile
+tick gives both snapshots to `nudgeStalledPoolClaims`, so a bead slung after a
+warm slot's startup turn remains visible once desired-state binds it as that
+slot's trigger.
+
+The ready-routed snapshot is separate from `AssignedWorkBeads`; assignment and
+wake semantics remain assignee-only. It is also derived from the same
+`Ready()` demand result that selected the trigger, rather than the broader open
+route-repair scan, so blocked open work cannot drive the nudge backstop.
+
+Store refs remain attached to the snapshot. The backstop matches
+`gc.trigger_bead_store_ref` as well as the bead ID, preventing independent city
+and rig stores with the same bead ID from waking the wrong slot. Legacy
+sessions without a trigger store ref use an unambiguous ID-only fallback.
+
+The existing persisted `observe → nudge → backoff → give-up` pacing and attempt
+cap are unchanged, and the fix adds no store read to the reconcile hot path.

+## Summary
+
+The supervisor session stream and transcript endpoints accept two requested
+formats today: `conversation` (the default) and `raw`. The transcript/peek path
+can also return `format: "text"` when no transcript exists yet and pane output
+is the only observable source; that is a fallback response shape, not a third
+requested query format. `conversation` is **lossy by design** — it flattens
+every provider's content blocks into a single `outputTurn.Text` string,
+replacing a tool call with `[name]`, truncating a tool result to 500
+characters, and redacting thinking to the literal `[thinking]`
+(`internal/api/handler_agent_output_turns.go:34-49,81-94`). `raw` is the
+opposite: provider-native JSON forwarded as `SessionRawMessageFrame` values.
+The raw contract is full-fidelity pass-through for valid provider frames; the
+current implementation has one transport-validity caveat, escaping malformed
+literal control characters inside JSON strings before emission so SSE never
+sends invalid JSON. The enclosing stream/transcript envelope carries only a
+`provider` identifier — so **every consumer must re-implement per-provider
+frame parsing** to recover structure
+(`internal/api/session_frame_types.go:26-150`;
+`internal/api/supervisor_city_routes.go:13-21`).
+
+The result is that rich structured consumers cannot be built on the supervisor
+API without each client owning a fragile, untested, client-side normalization
+layer for 17 built-in profiles spanning fewer provider transcript families.
+This is precisely what MC does today — its server reads `format=raw` and
+reconstructs full fidelity (tool inputs, structured tool results, thinking,
+usage, subagent nesting) before its clients consume the transcript. That work
+is duplicated in every consumer that wants rich presentation or programmatic
+access, and it lives one layer removed from the provider knowledge that already
+exists *inside* Gas City.
+
+This design adds a third requested format, **`format=structured`**, that emits
+Gas City's already-parsed content blocks as a typed, versioned schema — text,
+thinking (with signature when available and allowed), tool calls (with full
+input), tool results (with structured Bash/Grep/Read shapes where GC can derive
+them), interactions, usage, model, and stop reason. Inline-subagent
+relationships remain part of the north star, but are deliberately excluded
+from `session.structured.v1`; `ga-mb46n3` owns a later version. The
+per-provider knowledge stays in **one tested place near the source**
+(`internal/sessionlog` / `internal/worker`), and **any** consumer — a chat UI,
+the dashboard, an external client — gets a rich, provider-agnostic event model
+without duplicating provider parsers.
+
+The north-star goal, and the primary success criterion for this design, is a
+**rich, complete, unified, provider-neutral, structured, typed stream of
+data** that exposes 100% of the semantically available data from every
+supported provider without encoding UI decisions. A client that requests
+`format=structured` must be able to consume the data programmatically, render a
+rich GUI comparable to MC, build a CLI or analytics view, or
+persist its own normalized model without falling back to provider-specific
+parsing.
+
+Completeness does **not** mean shipping provider-native JSON objects,
+provider-native field names, or display HTML on the structured wire. The
+provider-native evidence remains available through `format=raw`; the
+structured contract is the typed normalization target. If MC or a
+provider-specific adapter can recover a useful fact from raw provider data,
+Gas City should expose the fact as provider-neutral typed data, not as HTML,
+anonymous JSON, or provider-shaped escape hatches. When a provider exposes a
+fact that the current schema cannot represent, Gas City must add or extend
+typed provider-neutral fields/result families and tests rather than dropping
+the fact, hiding it in an untyped map, or pushing native provider shape to the
+client.
+
+The headline finding from the cross-codebase and provider-format audit behind
+this spec: Gas City now parses provider frames into typed blocks for all 17
+built-in provider profiles when a supported native transcript or configured
+capture source is available. The dominant gap is not a lack of a structured
+wire shape — it is that Gas City's API flattens the structure it already has,
+and several providers need either modernized readers, managed capture, or
+fixture hardening because their public persisted transcript is not a rich
+complete trace. One cross-cutting carrier/schema change therefore unlocks most
+fidelity immediately; targeted provider adapters close the remainder.
+This is **transcript-schema parity**, not end-to-end provider parity: provider
+resume, hooks, MCP projection, skills, and runtime behavior remain governed by
+their own provider-specific designs.
+
+## Background: what already exists
+
+### Provider frames are already parsed per family
+
+`ReadProviderFile` dispatches by `ProviderFamily` to a dedicated reader per
+vendor (`internal/sessionlog/reader.go`): `ReadAuggieFile`, `ReadAmpFile`,
+`ReadCodexFile`, `ReadCopilotFile`, `ReadGeminiFile`, `ReadGrokFile`,
+`ReadKimiFile`, `ReadKiroFile`, `ReadMimoCodeFile`, `ReadOpenCodeFile`,
+`ReadPiFile`, `ReadAntigravityFile`, and the default Claude JSONL DAG reader
+(`ReadFile`). Each one translates that vendor's native transcript into the
+common `sessionlog.Entry` / `ContentBlock` shape
+(`internal/sessionlog/entry.go:60-77`) **and** preserves the original
+provider-frame bytes in `Entry.Raw` for raw pass-through. Valid raw frames are
+byte-preserved by the API; malformed string control characters are escaped as a
+transport-validity repair before emission.
+
+This is the per-provider translation layer the structured format needs. It
+is not greenfield.
+
+### The fidelity is parsed, then discarded or only partially carried
+
+`sessionlog.ContentBlock` already retains full tool input
+(`Input json.RawMessage`, `entry.go:73`), full tool-result content
+(`Content json.RawMessage`, `entry.go:75`), `IsError` (`entry.go:76`), text,
+and structured interaction fields (`entry.go:64-71`). The normalized
+`worker.HistoryBlock` mirrors the core block shape and has a first-class
+`HistoryInteraction` pointer plus initial `StructuredInput` /
+`StructuredResult` carriers for provider-neutral tool data
+(`internal/worker/types.go`). The structure now survives through the worker
+history path used by `format=structured`, but legacy `conversation` output
+still deliberately throws it away into a flat string
+(`internal/api/handler_agent_output_turns.go:26-54,73-101`). The remaining
+structured-format work is to expand those carriers and push every
+provider-specific extraction rule into provider/sessionlog normalization rather
+than reintroducing inference at the API edge.
+
+What the typed model still needs to complete:
+
+- **complete thinking provider coverage** — `ContentBlock` and `HistoryBlock`
+  now carry canonical thinking text plus a provider-neutral `signature` marker,
+  and `format=structured` gates both thinking text and its signature behind
+  `include_thinking=true`.
+  Remaining work is to normalize every provider's thinking/reasoning dialect
+  into that carrier, including encrypted or signature-only reasoning evidence
+  where available.
+- **complete usage / model / stop_reason coverage** — the normalized worker
+  history entry now carries `model`, `stop_reason`, and typed token usage when
+  those facts are present on the provider message or preserved raw frame. Claude,
+  Pi-family, Gemini-style top-level model fields, and similar direct evidence can
+  flow to `format=structured`. Codex per-invocation `token_count` events are
+  parsed through `ExtractCodexTailUsage` and correlated to the nearest visible
+  assistant message so `model`, token usage, and reported context window flow
+  through the same provider-neutral structured usage fields.
+- **complete structured tool-result families** — an initial worker carrier
+  exists for
+  command/stdin/read/grep/glob/edit/search/fetch/todo/plan/question/task/text data,
+  including typed patch hunks, todo before/after lists, plan text/steps,
+  question answer maps, and task/subprocess status/output, but not every
+  provider-specific result family from the MC audit has a first-class
+  provider-neutral DTO yet.
+- **inline subagent nesting is outside v1** — subagent mappings and transcript
+  reads exist as separate worker/API surfaces (`AgentMappings`,
+  `AgentTranscript`), but `session.structured.v1` deliberately has no reserved
+  lineage fields. A later version may add lineage after real provider evidence
+  establishes stable parent/child identifiers and transcript joins
+  (`ga-mb46n3`). These are provider inline subagents, not Gas City formula/drain
+  fanout; drain correlation stays in beads, convoys, formulas, and events.
+
+### Provider coverage contract
+
+`format=structured` is a provider-neutral projection over all 17 built-in
+provider profiles. The source adapter may read a native transcript, an official
+export, a live NDJSON stream, an ACP event log, or a Gas City managed capture
+file; the structured wire shape is the same either way. If a provider's native
+local transcript omits tool output or file changes, Gas City must capture those
+facts through that provider's hook/stream/ACP surface before claiming rich
+structured coverage. It must not forward native provider JSON as a shortcut.
+
+Builtin provider profiles live in `internal/worker/builtin/profiles.go`.
+The current adapter/capture target is:
+
+| Profile | Structured source | Expected v1 fidelity |
+|---|---|---|
+| claude | Claude JSONL under `~/.claude/projects/...` | rich messages, tool calls/results, thinking placeholder/text when allowed, raw only for native frames |
+| codex | Codex rollout JSONL / `--json` event stream | rich tool calls/results; command and patch events normalize to Bash/Edit where derivable |
+| gemini | Gemini session records | rich tool calls/results, thoughts, token usage; reader must support current JSONL session format |
+| kimi | Kimi Code `agents/main/wire.jsonl` (and legacy context logs while supported) | rich main-agent and subagent messages, tool calls/results |
+| opencode | OpenCode export/mirror JSON | rich tool calls/results and interactions from message parts |
+| mimocode | MiMo Code export/session database mirror using the OpenCode-compatible shape | rich tool calls/results through the MiMo/OpenCode adapter |
+| groq | OpenCode-backed Gas City profile | same as OpenCode; no Groq-specific transcript dialect |
+| cerebras | OpenCode-backed Gas City profile | same as OpenCode; no Cerebras-specific transcript dialect |
+| pi | Pi JSONL under `~/.pi/agent/sessions` | rich messages, tool calls/results, Bash/Python execution where present |
+| omp | Oh My Pi JSONL under `~/.omp/agent/sessions` | same Pi-family adapter, including Bash/Python execution records |
+| antigravity | Antigravity transcript JSONL / brain artifacts | rich messages, tool calls/results, interactions, artifacts where exposed |
+| copilot | Copilot CLI session-state event log | rich for messages, `tool.execution_*`, command output, errors, and result-side edit diffs when present |
+| kiro | Kiro ACP JSONL event log under `~/.kiro/sessions/cli` | rich through ACP `session/update` events (`ToolCall`, `ToolCallUpdate`, `TurnEnd`); DB-only chat export needs sampling before use |
+| cursor | Cursor stream JSON plus Gas City hook capture | stream/hook captures normalize messages, tool calls/results, command output, read/write evidence, and result events; native local JSONL omits tool outputs and cannot provide complete rich results by itself |
+| amp | `amp --execute --stream-json` live capture | rich for execute/headless flows; retrospective local thread discovery is not a public stable source |
+| grok | captured Grok ACP JSONL (`session/update`) | rich for ACP capture; `--output-format streaming-json` and persisted `~/.grok/sessions` need fixture/schema validation before use |
+| auggie | captured Auggie ACP JSONL (`session/update`) | rich for configured ACP capture; saved-session `chatHistory` / node graph, SDK capture, and hook capture need fixture/schema validation before use |
+
+Practical consequence: the carrier + stop-flatten change immediately lights up
+the provider-normalized transcript families for all 17 built-in profiles where
+GC has either a native transcript reader or configured capture. Remaining gaps
+require provider-reader hardening, managed capture, and real-provider fixtures,
+not client-side provider parsers.
+
+## The streaming ceiling (read before scoping "streaming")
+
+Both Gas City and MC operate on **whole committed
+frames**, not token/sub-frame deltas:
+
+- Claude Code writes whole JSONL message lines (a `tool_use` block is
+  committed with its `input` already complete; the `tool_result` arrives as
+  one later whole line). There are no `content_block_delta` /
+  `input_json_delta` frames in the transcript.
+- Codex writes a whole `function_call_output` per result; its
+  `exec_command_begin/end` progress frames are dropped today in
+  `skipCodexEventMsgType` (`internal/sessionlog/codex_reader.go:315-327`).
+- MC's streaming-delta assemblers exist but are **bypassed** in
+  production — they consume the same whole frames.
+
+Gas City's session stream already delivers these frames **live as they
+commit**, keyed by a cursor. So "streaming tool results" realistically
+means: *the tool call appears live, then its complete result appears live* —
+not bytes accumulating character-by-character. True sub-frame streaming
+would require tapping the provider's live API wire, which is outside the
+transcript-reader model.
+
+This spec therefore defines streaming in two phases (per direction set in
+review):
+
+- **Phase 1 — frame-granular streaming.** Structured blocks delivered live
+  as each transcript frame commits. This matches the best fidelity MC ships
+  today and is the v1 target.
+- **Phase 2 — sub-frame streaming.** Token/delta-level streaming by tapping
+  providers' live API output. A materially larger effort, scoped as future
+  work, not blocking Phase 1.
+
+One asymmetry to note: for **Gemini**, the GC reader reads the *whole file*
+via `os.ReadFile` (`internal/sessionlog/gemini_reader.go:19`). Existing stream
+machinery can re-read a valid whole-file snapshot on change and emit new entries
+by cursor, but a tolerant/incremental Gemini parser is still needed for robust
+frame-granular behavior while the provider file is being written. That is a
+Phase 1 hardening task for Gemini specifically.
+
+## Goals
+
+- A third session-stream/transcript format, `format=structured`, emitting a
+  typed, versioned, provider-agnostic message + block schema.
+- A complete typed normalization target for all 17 built-in provider profiles:
+  every provider fact that is present, derivable, or capturable must land in a
+  provider-neutral typed field/result family rather than being flattened,
+  ignored, hidden in untyped JSON, or exposed as provider-native shape.
+- Phase 1 rich support prioritizes the provider families currently under active
+  structured-session validation: Claude, Codex, Gemini, OpenCode-compatible
+  providers, Pi-family providers, Cursor stream/hook capture, Amp stream-json
+  capture, Grok ACP capture, and Auggie ACP capture. Every built-in profile uses
+  the same typed envelope and gracefully downgrades to provider-neutral fallback
+  data where provider-native or managed-capture evidence is incomplete.
+- Highest available fidelity for tool inputs, **structured tool results**, file
+  edits/diffs, thinking + signature, usage, model, stop-reason, artifacts,
+  interactions, and any future provider data family that clients may need for
+  display or programmatic use. Inline-subagent relationships remain a
+  north-star goal, but v1 deliberately reserves no lineage fields;
+  `ga-mb46n3` owns a later version.
+- 100% of provider data that is present, derivable, or capturable in a
+  provider run is represented as typed provider-neutral data in
+  `format=structured`; provider-native bytes remain a separate `format=raw`
+  escape hatch for audit/debug use only.
+- Zero client-side per-provider enrichment required to build MC-parity
+  presentation, build an alternate GUI/CLI, or consume the transcript
+  programmatically.
+- Provider-specific parsing/capture remains inside Gas City adapter code. A
+  client asking for `format=structured` must never need to know a provider's
+  native transcript dialect.
+- No UI-specific payloads in the structured contract: no HTML, pre-rendered
+  markdown, syntax-highlighted fragments, dashboard-only display blobs, or
+  other presentation encodings.
+- Existing additional families and aliases (`kimi`, `mimocode`, `groq`,
+  `cerebras`, `pi`, `omp`, `antigravity`, `copilot`, `kiro`, `amp`) gain useful
+  structured output without inventing new wire contracts.
+- A golden-fixture regression guard so server-side translation is safe
+  across provider/version drift.
+
+## Non-goals
+
+- Removing or changing `conversation` / `raw` (both remain; back-compat).
+- Sub-frame/token streaming (Phase 2, documented but not built here).
+- Passing provider-native JSON, provider-native metadata maps, or
+  provider-specific field names through `format=structured`. That remains the
+  purpose of `format=raw`.
+- Presentation concerns — markdown→HTML, syntax highlighting, diff
+  rendering, visual tool_use/result pairing. These stay in the consumer;
+  `format=structured` ships *data*, not HTML.
+
+## Tool result normalization contract
+
+MC proves the rich-data surface is possible today by reading Gas
+City's `format=raw`, parsing provider frames, and then adding display-ready
+HTML and other augment fields before the browser renders the transcript. Gas
+City should port the **data extraction algorithms**, not the presentation
+output. Provider-specific raw frames are normalized once, inside Gas City's
+provider/sessionlog layer, into typed provider-neutral tool inputs and tool
+results. API handlers then project those typed values to OpenAPI/Huma wire
+types. Clients may render HTML, colorized diffs, tables, or programmatic views
+from the data, but `format=structured` itself must not ship HTML,
+provider-native objects, anonymous JSON maps, or provider-specific field names.
+
+### Ownership boundary
+
+The normalization owner is the provider adapter path:
+
+- `internal/sessionlog/*_reader.go` maps provider transcript frames into common
+  content blocks and typed structured tool data.
+- `internal/worker` carries the normalized data as part of history snapshots.
+- `internal/api` only projects normalized history into Huma-registered wire
+  structs.
+- `cmd/gc/dashboard` renders the typed data but does not parse provider-native
+  transcript formats.
+
+The current implementation is partially aligned: the API projection consumes
+worker-carried typed structured input/result data, and the structured wire
+tests forbid native provider keys. `internal/api/session_structured_types.go`
+no longer infers tool semantics from provider-native JSON; if a worker history
+block lacks `StructuredInput` or `StructuredResult`, the structured API leaves
+that typed field empty instead of re-parsing native data. The remaining
+alignment work is to keep expanding provider/sessionlog/worker normalization
+until every supported provider's rich data is represented before it reaches
+the API edge. The end state is that provider-native field names appear only in
+provider adapters and `format=raw` fixtures, never in structured wire DTOs,
+API inference, or dashboard parsing code.
+
+### Non-negotiable wire rules
+
+- `format=structured` returns typed provider-neutral data, not display HTML.
+- Provider-specific fields such as `toolUseResult`, `resultDisplay`,
+  `_structuredPatch`, `_diffHtml`, `_highlightedContentHtml`, `call_id`,
+  `tool_use_id`, or raw SDK result objects must not cross the structured API
+  boundary.
+- Rich edit results expose typed patch hunks, file paths, result-side old/new
+  text, original-file text, and provider-reported edit flags such as
+  replace-all and user-modified state when present. A flat patch string may
+  remain as a convenience field while clients migrate, but it is not the only
+  rich edit representation.
+- Result-side edit evidence comes from provider result data: structured result
+  fields, result displays, patch-apply events, or textual result content that
+  is itself a patch. GC must not fabricate an edit result from a tool input and
+  claim the provider reported it.
+- Long-tail providers must degrade gracefully to existing typed neutral fields.
+  Unknown result data may use `kind: "text"`. Search inputs may use the typed
+  `query`, `pattern`, `file_path`, and `command` fields plus scalar `path`
+  entries in `arguments`; unknown argument names, nested values, and arbitrary
+  provider JSON remain available only through `format=raw`.
+- Serialization/deserialization stays at the edges. Internal code should carry
+  typed Go structs, and Huma/OpenAPI generated types are the wire source of
+  truth.
+
+### MC algorithm inventory
+
+MC has two relevant layers:
+
+1. `server/src/services/gc_message_format/*` translates raw provider frames
+   into richer app blocks.
+2. `server/src/services/render_enrichment/*` adds display-oriented augments
+   such as HTML and syntax-highlighted snippets.
+
+Only the data algorithms belong in Gas City structured normalization.
+
+| MC area | Algorithm to port to GC data | GC target |
+|---|---|---|
+| Codex tool invocation | Canonicalize names (`apply_patch` → edit, shell commands → bash, web search aliases), parse JSON-string arguments, preserve call context for results. | `internal/sessionlog/codex_reader.go` |
+| Codex shell classification | Reclassify `cat`, `sed -n`, `nl -ba ... \| sed -n`, `rg`, and `grep` shell commands into provider-neutral Read/Grep inputs, after unwrapping shell launchers such as `/usr/bin/env bash -lc "..."`, `/bin/bash -lc "..."`, and nested variants. | Codex reader/sessionlog normalization |
+| Codex output normalization | Strip `Output:` wrappers, parse nested JSON-string outputs, extract stdout/stderr/exit code/error state, and avoid treating no-match grep as a provider failure. | Codex reader/sessionlog normalization |
+| Codex event filtering and errors | Preserve user/assistant/reasoning/error events as provider-neutral messages, normalize error/stream-error/turn-aborted events into typed `system_event` data, and skip unknown provider event frames such as shutdown/diagnostic events instead of exposing native `event_msg` records on the structured wire. | Codex reader/sessionlog normalization |
+| Codex Read result | Strip `nl -ba` line number prefixes, compute `start_line`, `num_lines`, and `total_lines`. | typed Read result |
+| Codex Grep result | Distinguish `mode: "content"`, `mode: "files_with_matches"`, and `mode: "count"`; expose filenames, counts, and matched content. | typed Grep result |
+| Codex image blocks | Preserve user `input_image` evidence as provider-neutral image blocks with file path, external image URL, and MIME type; keep inline image bytes out of `format=structured`. | typed Image block |
+| Patch parsing | Parse raw `*** Begin Patch` / unified diff text into `{file_path, old_start, old_lines, new_start, new_lines, lines}` hunks, including multi-file patches. | typed Edit result |
+| Edit diff computation | When a provider result contains old/new/original edit fields or replace-all/user-modified flags, expose those facts as typed data and compute patch hunks from result-side old/new text when no provider hunk exists. Do not expose MC's HTML. | provider-specific Edit result normalizer |
+| Claude SDK tool results | Normalize Bash, Read, Edit, Write, Glob, Grep, TodoWrite, WebSearch, WebFetch, BashOutput, KillShell, TaskOutput, AskUserQuestion, and plan-mode result schemas. | Claude reader/sessionlog normalization |
+| Async shell stdin correlation | Link `WriteStdin` / stdin tools back to the parent shell command by normalizing provider shell/session identifiers to `task_id` and attaching the parent command as typed `linked_command` input data. | typed Stdin input/result |
+| Search result items | Flatten provider result arrays such as MC's nested WebSearch result `content` items into provider-neutral `{ title, url, snippet? }` items; parse URL-prefixed search output only when the tool context is a web query, not grep. | typed Search result `result_items` |
+| Gemini result display | Translate `resultDisplay.fileDiff`, file path, original content, and new content into typed edit/write data. | Gemini reader/sessionlog normalization |
+| Tool error classification | Classify explicit tool failures into provider-neutral categories such as user rejection, command failure, file error, validation error, timeout, network error, and unknown; expose cleaned messages and user rejection reasons as typed data, not UI badges. | typed `StructuredToolError` |
+| User prompt metadata | Extract opened IDE files, IDE selections, uploaded-file sections, and cleaned prompt text from user messages so clients do not parse prompt boilerplate. | typed `StructuredUserPrompt` |
+| Markdown/code rendering | Preserve source text, file path, language/truncation hints when derivable; do not pre-render HTML. | typed `language` / `truncated` data only; dashboard owns rendering |
+
+### Typed result families
+
+The first structured result families are sketched in the schema section. To
+reach MC richness without HTML, GC needs these provider-neutral DTOs over time:
+
+- **Command**: `stdout`, `stderr`, `exit_code`, `interrupted`, `truncated`,
+  `is_image`, command text, optional shell/task identifiers, status, stream
+  line counts, and timestamp when providers expose async shell output polling.
+  Shell-control results such as kill/stop messages expose the shell identifier
+  as neutral `task_id` and the provider result message as `stdout`/`content`;
+  they do not leak provider-native shell-control field names.
+- **Stdin**: async shell input tools expose the provider-neutral shell
+  identifier as `task_id`, the submitted stdin text as `text`, and the parent
+  shell command as `linked_command` when it can be derived from an earlier Bash
+  result. Provider-native identifiers such as `sessionId` and `shellId` stay in
+  `format=raw`.
+- **Tool errors**: failed tool results carry provider-neutral error metadata:
+  `category`, cleaned `message`, and optional `user_reason`.
+  Categories are `user_rejection`, `user_rejection_with_reason`,
+  `command_failure`, `file_error`, `validation_error`, `timeout`,
+  `network_error`, and `unknown`. This ports MC's data classification
+  algorithm without shipping MC's UI rendering.
+- **System events**: provider transcript events such as provider errors,
+  stream errors, and turn-aborted notices carry typed `system_event` metadata
+  with neutral `kind`, `category`, optional semantic `code`, and cleaned
+  `message`. Provider-native frame names and fields such as `event_msg` and
+  `codex_error_info` stay in `format=raw`.
+- **User prompts**: user messages carry cleaned prompt text, opened IDE file
+  paths, uploaded-file metadata, and IDE selection text as typed
+  `user_prompt` data. Raw provider/user text remains available through the
+  text block and `format=raw`; clients that want MC-style display can use the
+  typed prompt metadata without parsing IDE tags or upload sections.
+- **Read/Write**: `file_path`, `content`, `language`, `num_lines`,
+  `start_line`, `total_lines`, optional result-side `patch` / `patch_hunks`
+  for providers that report write diffs, and optional image metadata where
+  providers return images. Write result patches still come only from
+  result-side evidence, never from the write input text.
+- **Edit/Patch**: operation type, `file_path`, `file_paths`, optional raw
+  neutral patch text, `patch_hunks`, `old_string`, `new_string`,
+  `original_file`, `replace_all`, and `user_modified` when the provider result
+  reports them.
+- **Grep/Glob**: mode/pattern where applicable, filenames, counts, matched
+  content, applied limit, `duration_ms`, and truncation state when present.
+- **Search/Fetch**: query/url, result items, `status_code`, `status_text`,
+  bytes, `duration_ms`, and response content where present.
+- **Todo**: todo input lists plus result-side `old_todos` / `new_todos`
+  before/after lists.
+- **Plan**: plan text, explanation text, and provider-neutral plan step lists.
+- **Question**: full question arrays, headers, option labels/descriptions,
+  multi-select state, selected answer, and answer maps.
+- **Task/Subprocess output**: task id/type/status/description/output/exit code.
+  Bash results that launch background work may also carry the neutral task id
+  while remaining `kind: "bash"`.
+- **Fallback text**: neutral text with `kind: "text"` for providers or tools
+  without a known typed result.
+
+Adding a new result family is a schema change: update Go wire structs, OpenAPI,
+generated clients, dashboard types, and golden fixtures together.
+
+### Provider normalization status
+
+| Provider family | Current GC state | Required gap closure |
+|---|---|---|
+| Claude | Reads JSONL blocks; Claude `toolUseResult` sidecar evidence is normalized by the sessionlog entry layer into provider-neutral result evidence before worker inference, covering initial command/edit/read/glob/search/fetch/todo/plan/question/task/text data. Read sidecars with nested `file` evidence flatten to neutral file/range/content fields; WebSearch sidecar `results[].content[]` items flatten to neutral `result_items` with title, URL, and snippet; read/write file path evidence derives provider-neutral `language` hints before API projection. | Expand Claude SDK result parsing in sessionlog/worker for the remaining MC tool family set; continue shrinking raw Claude key handling outside the reader/sessionlog boundary. |
+| Codex | Reads rollout JSONL; the reader normalizes JSON-string tool arguments, canonicalizes common tool input/result keys, preserves user image blocks as provider-neutral `image` blocks (`file_path`, external `image_url`, `mime_type`), preserves web-search queries as typed search input while keeping provider-native actions and unrecognized extra fields raw-only, derives provider-neutral command/read/grep input evidence for recognized shell commands including file `language`, unwraps common shell launchers (`/usr/bin/env bash -lc`, `/bin/bash -lc`, nested variants) before read/grep classification, strips Codex `Output:` wrappers, parses nested JSON command results, derives result `is_error` from explicit flags/status, JSON/text exit-code forms, and error-like text, normalizes read result content/ranges/language and grep result mode/count/filename summaries, treats no-match grep JSON results as zero-result search data rather than provider failures, parses URL-prefixed web-query output into neutral `result_items`, and carries patch-apply evidence before worker inference. Worker normalization prefers those neutral result fields and keeps typed edit hunk inference plus generic read/grep fallback for older fixtures. | Continue porting the remaining MC Codex output variants and real-provider fixtures, especially richer stderr/status forms and richer web/search result payloads beyond current URL/text result summaries. |
+| Gemini | Current JSONL message `model`, nested `tokens.cache.read/write`, `type:"error"` messages, and tool-result status flow to provider-neutral structured metadata, typed `system_event`, error/text fields. Whole-file write inputs normalize as `kind: "write"` with file path/content text instead of fabricated input patches; `resultDisplay.fileDiff` and result-side file path evidence normalize in the Gemini reader into neutral patch data for current edit/write fixtures. | Normalize the remaining current Gemini `resultDisplay` and tool-response variants to typed edit/write/search/fetch data in the Gemini reader; add incremental parsing for live frame-granular streaming. |
+| Kimi | Useful tool calls/results via reader; common tool input/result object keys normalize to provider-neutral names before worker inference, native `is_error` / `isError` / status fields normalize to provider-neutral `is_error`, and result-side patch evidence produces typed edit hunks. | Expand typed command/read/edit parsing where newer Kimi wire evidence supports richer execution, search, and artifact data. |
+| OpenCode/MiMo/Groq/Cerebras | OpenCode-compatible reader gives useful blocks, neutralizes common camel-case tool input/output keys before worker inference, and export `info.modelID` / `info.tokens` now flow to provider-neutral structured model/usage metadata, including reasoning tokens when present. Result-side patch evidence from OpenCode tool output states produces typed edit hunks; input-only edit evidence still does not fabricate result diffs. | Expand OpenCode tool output-state normalization beyond the current common command/edit/file fields where native evidence supports richer read/grep/artifact data. |
+| Pi/OMP | Pi-family reader provides messages/tool records, preserves generic image-part metadata as provider-neutral `image` blocks, normalizes common tool input/result object keys before worker inference, and OMP `bashExecution` / `pythonExecution` records emit provider-neutral execution fields that normalize through worker history into typed Bash/Python structured results. Result-side Pi patch evidence produces typed edit hunks. | Expand beyond current command/read/edit/image support where Pi-family evidence exposes richer search/artifact data; per-invocation usage is still absent. |
+| Antigravity | Reader provides messages/tools/interactions, normalizes common tool input/result object keys before worker inference, maps native status fields to provider-neutral `is_error`, preserves whole-file write inputs as `kind: "write"` with file path/content text, and result-side diff/patch evidence produces typed edit hunks. | Expand typed result extraction for command/artifact/search shapes where Antigravity exposes richer evidence. |
+| Copilot | Dedicated reader maps `~/.copilot/session-state/<sessionId>/events.jsonl` into provider-neutral messages and tool use/result blocks, including command stdout/stderr/exit code, failed-tool error content, and result-side patch/edit evidence when present. Keyed discovery uses the session-state directory and verifies `workspace.yaml` or `session.start.data.context.cwd` against the workdir. | Expand against real provider fixtures as Copilot event variants evolve, including any separate terminal-output chunk events and richer file-change records beyond current `tool.execution_complete` result evidence. |
+| Kiro | Dedicated reader maps Kiro ACP JSONL `session/update` events under `~/.kiro/sessions/cli/<session-id>.jsonl` into provider-neutral assistant text, `tool_use`, and `tool_result` blocks. ACP `rawInput` / `rawOutput` fields normalize to neutral command/file/edit/result keys; ACP diff content normalizes to result-side patch data. Keyed discovery validates the JSON sidecar or JSONL context cwd against the workdir. Persisted `AssistantMessage` / `ToolResults` history frames are supported where they carry message content. | Capture real Kiro ACP fixtures to harden field variants and chunk coalescing; sample the default chat database/export path before claiming retrospective rich chat-session parity. |
+| Amp | Dedicated reader maps captured `amp --execute --stream-json` JSONL into provider-neutral user/assistant/system messages, tool-use blocks, tool-result blocks, thinking blocks when present, usage metadata, and final result system events. Tool inputs/results normalize common command/file/edit/result keys before worker inference; JSON-string tool result payloads are decoded and neutralized before reaching `format=structured`. Discovery uses configured GC-owned capture paths only, because Amp does not document a stable retrospective local transcript store. | Add managed stdout capture before enabling stream-json in the builtin profile; validate against real Amp tool-result fixtures and subagent `parent_tool_use_id` cases. |
+| Grok | Dedicated reader maps captured Grok ACP JSONL `session/update` events into provider-neutral assistant text, `tool_use`, and `tool_result` blocks by reusing the ACP normalization path. ACP `rawInput` / `rawOutput` fields normalize to neutral command/file/edit/result keys; ACP diff content normalizes to result-side patch data. Discovery uses configured GC-owned capture paths only, because the documented `~/.grok/sessions` persisted schema and `streaming-json` event schema still need fixture validation before use. | Add managed ACP/headless capture for builtin sessions if GC should launch Grok in that mode; collect real Grok ACP and streaming-json fixtures before claiming persisted/headless parity outside configured captures. |
+| Auggie | Dedicated reader maps captured Auggie ACP JSONL `session/update` events into provider-neutral assistant text, `tool_use`, and `tool_result` blocks by reusing the ACP normalization path. ACP `rawInput` / `rawOutput` fields normalize to neutral command/file/edit/result keys; ACP diff content normalizes to result-side patch data. Discovery uses configured GC-owned capture paths only, because GC does not yet rely on a stable retrospective local Auggie transcript store. | Add managed ACP, SDK, or hook capture for builtin sessions; collect real Auggie ACP/hook/SDK fixtures before claiming saved-session, hook, or live SDK parity outside configured captures. |
+| Cursor | Dedicated reader maps Cursor stream JSON and configured hook captures into provider-neutral user/assistant messages, `tool_use`, `tool_result`, and final result system events. Cursor stream tool calls normalize read/write/shell evidence into neutral file, command, output, and edit/result keys; configured capture discovery validates cwd and session ID. Native local Cursor transcripts intentionally omit tool outputs, so they are not a complete rich source by themselves. | Add managed stream/hook capture for builtin Cursor sessions; collect real Cursor stream/hook fixtures across CLI versions before claiming parity beyond configured captures. |
+
+### Implementation sequence
+
+1. Extend structured result DTOs with typed patch hunks and file path lists.
+   Keep the existing flat `patch` field temporarily for compatibility.
+2. Port MC patch parsing as typed data and update dashboard rendering to prefer
+   typed hunks when present.
+3. Tighten Codex read/grep/output normalization, including line-number
+   stripping and grep mode detection.
+4. Move provider-specific result extraction from `internal/api` into
+   `internal/sessionlog` and `internal/worker` carriers.
+5. Add first-class and high-coverage typed result normalizers from real
+   provider fixtures, including Claude, Codex, Gemini, OpenCode-compatible
+   providers, Grok ACP, Auggie ACP, and existing Pi-family evidence.
+6. Build a golden fixture corpus from real `format=raw` transcripts and assert
+   provider-neutral structured output for every first-class provider.
+7. Expand long-tail providers with reader/capture work while preserving typed
+   graceful fallback for all 17 profiles.
+
+Each step should land with tests that prove both positive fidelity and negative
+provider-neutrality: rich data is present, HTML is absent, and native provider
+field names do not appear on the structured wire.
+
+Current implementation status: steps 1-3 are partially implemented for the
+initial
+command/stdin/read/grep/glob/edit/search/fetch/todo/plan/question/task/text families.
+The worker/API carrier now also projects direct-entry `model`, `stop_reason`,
+and typed token usage when provider evidence is present; Codex `token_count`
+events are correlated to structured assistant messages in worker history. Step
+4 is complete for the API edge: structured API projection no longer performs
+provider-native tool inference. Step 4 remains incomplete at the
+provider-normalization layer until every extraction algorithm lives in
+provider/sessionlog/worker code and the remaining first-class provider result
+families are covered by real fixtures.
+
+## Gap analysis: spirit vs. implementation
+
+This gap list is part of the spec, not a transient review note. The structured
+stream is not done when the API can return typed frames; it is done when a
+client can build MC-class presentation, alternate GUIs, CLIs, analytics, and
+programmatic automations from typed provider-neutral data without provider
+parsers, native JSON escape hatches, or HTML.
+
+### Weakest current areas
+
+- **Provider parity is not proven until it is fixture-backed.** The code now
+  has typed paths and graceful downgrade for every built-in profile, but the
+  evidence must be a real provider/version matrix: Claude, Codex, Gemini,
+  OpenCode-compatible providers, Pi-family providers, Copilot, Kiro, Cursor,
+  Amp, Grok, Auggie, Kimi, and Antigravity. Synthetic fixtures are useful unit
+  tests, not proof that current live provider sessions produce rich structured
+  output.
+- **Capture is the highest live-session risk.** Providers whose retrospective
+  local transcript is incomplete or undocumented must have GC-managed capture
+  for the source that actually contains rich data: stdout stream-json, ACP
+  `session/update`, hook output, SDK event streams, or provider event logs. A
+  profile that depends on a manually configured capture path should be reported
+  as a degraded structured source, not described as complete.
+- **The central normalizer must keep shrinking.** Shared helpers for patch
+  parsing, command output normalization, shell unwrapping, and common
+  provider-neutral key canonicalization are useful. Provider-specific semantic
+  evidence should be emitted by provider readers/adapters, then carried by
+  worker history. A generic worker/API normalizer that guesses semantics from
+  arbitrary native-looking fields recreates the client-side parser problem on
+  the server.
+- **Provider-native key leakage is still the easiest regression.** Fallback
+  `arguments: [{name, value}]` is only acceptable when names are
+  provider-neutral or intentionally generic. Native field names such as
+  `toolUseResult`, `resultDisplay`, `call_id`, `tool_use_id`, `sessionId`, and
+  provider SDK object names belong in `format=raw`, fixtures, and adapters, not
+  in structured DTOs.
+- **Structured pagination and cursors must stay first-class.** Structured
+  history and stream consumers need the same navigability as raw/conversation:
+  `before`, `after`, stable entry cursors, and explicit pagination metadata.
+  This branch adds structured cursor support, but provider-conformance tests
+  must include cursor behavior so future structured work does not silently fall
+  back to whole-session dumps.
+- **Inline-subagent lineage is deferred beyond v1.**
+  `session.structured.v1` has no reserved lineage fields. `ga-mb46n3` owns a
+  later, evidence-backed version that may add typed parent/child relationships,
+  parent tool call references when available, and transcript linkage without
+  confusing provider inline subagents with Gas City formulas, drains, convoys,
+  or beads.
+- **Dashboard rendering must not be the evidence source.** Dashboard tests
+  should prove that typed data renders rich results and colorized diffs, but the
+  provider truth must be proven below the dashboard: native transcript/capture
+  fixture -> provider reader -> worker history -> typed API/SSE. A beautiful
+  dashboard over mocked payloads does not prove `format=structured`.
+- **Spec claims must be mechanically tied to coverage.** Provider counts,
+  first-class status, and supported result families should be backed by fixture
+  manifests or conformance tables that fail tests when a provider/profile is
+  added without structured evidence.
+
+## Architectural alignment
+
+Scoped to respect Gas City's load-bearing invariants (AGENTS.md):
+
+- **Object model at the center.** The per-provider translation and the new
+  carrier fields land in the domain (`internal/sessionlog`,
+  `internal/worker`); `internal/api` only *projects* the normalized history
+  into the structured wire shape. No domain logic moves into the API layer,
+  and the carrier extends the canonical normalized-history model rather than
+  forking a parallel one. The stream path already uses `worker.Handle.History`;
+  the transcript path still reads `sessionlog` directly today, and AGENTS.md
+  explicitly says the worker-boundary migration is not a sessionlog read-site
+  inventory. Structured transcript implementation should prefer the worker
+  history/transcript boundary where practical, but any remaining direct
+  `sessionlog` use in `internal/api` must stay a projection over the domain
+  parser, not a second parser.
+- **Transport, not judgment.** Frame→block translation and Codex
+  command-shape classification must remain deterministic adapter
+  normalization, not role logic or user-work reasoning. `format=structured`
+  is a projection of existing domain data, not a new SDK primitive.
+- **Upstream alignment.** The carrier touches upstream-owned files
+  (`sessionlog/entry.go`, `worker/types.go`, `internal/api` handlers). Keep
+  each edit minimal and idiomatic so it rebases cleanly, and treat this
+  feature as a strong candidate to propose upstream rather than carry as
+  fork-only divergence.
+- **Required reading before implementing.**
+  `engdocs/architecture/api-control-plane.md` (typed-wire rules and the
+  raw-frame opacity exception) and `engdocs/contributors/huma-usage.md`
+  (SSE/Huma registration), per AGENTS.md.
+
+## Proposed schema
+
+Typed wire only — no bare `map[string]any` / `json.RawMessage` on the API or
+SSE wire path. The concrete Huma-registered Go wire structs are the source for
+the generated OpenAPI; the pseudocode below is a design sketch for those
+structs, and `TestOpenAPISpecInSync` must pass.
+
+`format=structured` has an additional provider-neutrality contract:
+**it must not send provider-native transcript frames, provider-native JSON
+leaves, or provider-specific dialect shapes over the wire.** The point of the
+format is that clients can render rich session output without knowing that
+Codex calls a field `call_id`, Claude calls it `tool_use_id`, or Gemini stores
+tool arguments under a different object shape. Exact provider frames remain
+available only through `format=raw`.
+
+Every tool input, tool result, interaction, usage record, and diagnostic exposed
+by `format=structured` must therefore be one of:
+
+- a provider-neutral typed shape Gas City owns (preferred for known tool
+  families such as Bash/Grep/Read/Edit/Search and known interaction fields);
+- or a provider-neutral text fallback such as `{ kind: "text", text }`.
+
+The `arguments` carrier is not a generic fallback for unknown provider fields.
+Its input names are schema-approved scalar fields; v1 admits `path` for repeated
+search paths. Unknown names and object or array values are omitted from the
+structured projection. Consumers that need byte-level provider evidence must
+ask for `format=raw`.
+
+For edit results specifically, `tool_result.structured.patch` must come from
+result-side evidence: a provider's structured tool-result field, a provider's
+file-diff result display, or textual result content that is itself a patch.
+Gas City may normalize those result-side shapes into one provider-neutral patch
+string for the wire. It must not synthesize a result patch from the preceding
+tool input (`old_string` / `new_string`, `apply_patch` input, write contents,
+or similar). Tool inputs can still expose their own provider-neutral input
+shape, but the result must represent what the provider reported after running
+the tool.
+
+Do not use anonymous maps, raw JSON fields, unregistered unions, or "any JSON"
+carriers directly on the structured API types.

+
+The concrete Go wire structs should use Gas City's normal JSON spelling shown
+above (`schema_version`, `stop_reason`, `tool_call_id`, `is_error`, etc.). Use `tool_call_id`
+even when the native provider calls the value `tool_use_id`, `call_id`, or
+something else; native spelling belongs only in `format=raw`.
+
+The structured transcript response and the structured stream preserve the
+worker history envelope, not only individual messages. REST returns
+`operation: "snapshot"` and an opaque `history.cursor.resume_token`. The client
+passes that token as `after_cursor` when opening SSE; browser reconnects send
+the latest SSE `id` as `Last-Event-ID`. Structured SSE frames use three typed
+operations: `snapshot` replaces the initial projection, `upsert` replays the
+previous mutable tail inclusively plus later messages, and `reset` carries a
+full replacement (including an empty array) with a typed reason. Generation
+changes remain evidence, but the volatile observation value is not itself a
+reset discriminator. Cursor invalidation, history rewrites, stream rotation,
+degraded continuity, and tail state remain visible on the wire, matching
+`worker-conformance.md` §4.3 rather than silently replaying or dropping history.
+
+The stream keeps the lifecycle event kinds (`activity`, `pending`,
+`pending_cleared`, `heartbeat`) and adds a versioned structured message payload.
+Huma SSE registration maps **one concrete Go payload type to one SSE event name**
+(`internal/api/sse.go`; `internal/api/supervisor_city_routes.go`), so Phase 1
+uses a distinct `event: structured` frame for
+`SessionStreamStructuredMessageEvent`. The existing `turn` event remains the
+conversation payload, `message` remains the raw provider-frame payload, and the
+structured payload carries `schema_version` inside `data`. `conversation` and
+`raw` payloads remain unversioned for back-compat.
+
+Pending interactions form one authoritative slot, not an append-only event
+history. After the initial structured projection, every connection immediately
+reseeds its current pending interaction. A `pending` frame replaces the slot,
+including same-ID replays and request A changing to request B;
+`pending_cleared` removes the resolved request. On every EventSource open or
+reconnect, clients clear any locally cached pending interaction before accepting
+the server reseed. This prevents a stale interaction from surviving when the new
+connection has no pending request and therefore no prior request ID for the
+server to clear.
+
+When the transcript path has no structured history yet, `format=structured`
+still honors the requested structured wire contract. The response or stream
+frame must use `format: "structured"`, include `schema_version`, and include a
+degraded `history` envelope with `continuity.status = "degraded"` plus a
+`transcript_unavailable` diagnostic. If live pane text is the only observable
+source, it may appear only as a provider-neutral `text` block on a degraded
+`assistant` message in `structured_messages`; the server must not return
+`format: "text"` to a structured request and must not forward provider-native
+frames through the structured format. This graceful downgrade is mandatory for
+every built-in provider, including providers whose rich transcript parser has
+not landed yet, so clients can render one provider-neutral shape without
+learning provider file formats.
+
+### Thinking-exposure policy
+
+`conversation` redacts thinking by deliberate policy
+(`handler_agent_output_turns.go:46-49`). `format=structured` is itself
+opt-in, but to avoid silently reversing that stance for consumers who don't
+want reasoning, thinking blocks are gated behind an explicit
+`include_thinking=true` query parameter; default omits both the `thinking`
+block's text and its signature (keeping a typed placeholder block so ordering
+is preserved). The parameter is declared on the Huma input structs so it
+appears in OpenAPI; do not read it through raw URL inspection. City read
+authorization applies to both REST and SSE. Maintainer/product-security owner
+Julian Knutsen approved this v1 policy on 2026-07-14.
+
+## Phasing
+
+### Phase 1 — Structured, frame-granular format
+
+**1A. Carrier + schema + stop-flatten (cross-cutting; currently unlocks 12
+transcript families and 16 profiles).**
+
+- `internal/sessionlog/entry.go` — carry `Thinking` and `Signature` on
+  `ContentBlock`; map provider thinking/reasoning fields into canonical
+  thinking text and neutral signature markers.
+- `internal/worker/types.go` — add `Usage`, `Model`, `StopReason` to
+  `HistoryEntry`; add signature and structured-result carriers to
+  `HistoryBlock`.
+- `internal/worker/sessionlog_adapter.go:293-368` — decode
+  `message.usage` / `model` / `stop_reason` (reuse the cache-aware parser in
+  `tail_usage.go`) and populate the new fields instead of only `cloneRaw`.
+  Preserve context-window/fullness data from `TailMeta.ContextUsage` when the
+  server can derive it; do not make clients reimplement model-window lookup.
+- `internal/api/` — register `format=structured` on the Huma session stream
+  (`huma_handlers_sessions_stream.go`) and transcript
+  (`huma_handlers_sessions_query.go`) handlers, emitting `StructuredMessage`;
+  add the typed wire types, the Huma input docs/validation, and the OpenAPI
+  SSE schema; leave `conversation`/`raw` untouched.
+- `cmd/gc/dashboard/web/src/generated/` and `internal/api/genclient/` —
+  regenerate clients from the Huma spec. The dashboard uses generated
+  `streamSession` SSE types and currently bridges heterogeneous frame payloads
+  opaquely, so this is a generated-client/API-shape change, not just a server
+  change.
+- Live delivery reuses the existing tail/cursor stream machinery — frames
+  are emitted structured as they commit (frame-granular streaming).
+
+Outcome: claude + codex + gemini + kimi + opencode + mimocode + groq +
+cerebras + pi + omp + antigravity emit useful structured blocks immediately,
+with fidelity bounded by the carrier fields they can populate and by targeted
+reader gaps closed below.
+
+**1B. Codex structured tool results** (`internal/sessionlog/codex_reader.go`).
+
+The load-bearing prerequisite is a `call_id → {toolName, readShellInfo}`
+context map threaded through `ReadCodexFile`'s loop — without it a
+`function_call_output` cannot know whether it was Bash/Grep/Read, which is
+exactly why Codex results are opaque today. Then:
+
+- tool-name canonicalization (`apply_patch`→Edit, `shell_command` /
+  `exec_command`→Bash, `web_search_call` / `search_query`→WebSearch);
+- command-shape reclassification (`cat`/`sed`/`nl`→Read, `rg`→Grep) with a
+  quote-aware tokenizer;
+- structured result parsers: Bash (strip `Output:\n`, split stdout/stderr,
+  exit code), ripgrep (content vs files-with-matches; no-match ≠ error),
+  read (line numbering, strip `nl` prefixes);
+- exit-code / `is_error` derivation from text and fields;
+- `web_search_call` handling; reasoning fallback to the item's `content`
+  when `summary` is empty, and `encrypted_content` → `signature: "encrypted"`;
+- `token_count` event → per-entry usage; capture `model` and the reported
+  context window (currently implemented in worker history via
+  `ExtractCodexTailUsage` correlation).
+- `codexResponseItem` already carries typed `content`, `summary`, `arguments`,
+  `input`, and `output`; `encrypted_content` is carried only as neutral
+  signature evidence. Keep encrypted provider bytes off the structured wire.
+
+**1C. Gemini and Kimi current-format gaps.**
+
+- Gemini: current JSONL session format is supported; `model`, nested
+  `tokens.cache.read/write`, `type:"error"` messages, and tool-result status
+  now normalize to provider-neutral metadata/usage/text/error fields. Remaining
+  work: cover every current `resultDisplay` variant and add an **incremental
+  parser** so live frame-granular streaming works (the legacy reader is
+  whole-file).
+- Kimi: prefer current `~/.kimi-code/sessions/<workDirKey>/<sessionId>/agents/main/wire.jsonl`
+  and subagent `wire.jsonl` files, while retaining legacy context-log support
+  until it is no longer useful.
+
+**1D. Alias and Pi-family hardening.**
+
+- Route `groq` and `cerebras` through the OpenCode adapter. They are Gas City
+  OpenCode-backed profiles, not distinct transcript dialects.
+- Route `omp` through the Pi-family adapter and normalize OMP `bashExecution`
+  / `pythonExecution` messages to provider-neutral Bash/Python tool-result
+  shapes with output, exit code, cancellation/interruption, and truncation
+  (covered in worker history).
+- Kimi and Antigravity status/error fields normalize to provider-neutral
+  `is_error`; remaining work is richer typed result extraction where their
+  native evidence exposes command/edit/artifact/file shapes.
+- Note: per-invocation usage is absent for some long-tail readers today. Pi
+  exposes compaction `PreTokens`, but that is context-boundary evidence, not
+  response usage.
+
+**1E. Copilot reader hardening.**
+
+- Copilot: `~/.copilot/session-state/<sessionId>/events.jsonl` is now mapped
+  through the sessionlog provider layer into neutral user/assistant/system
+  messages, `tool.execution_start` / assistant `toolRequests` tool-use blocks,
+  and `tool.execution_complete` tool results. Command output fields normalize
+  to `stdout`, `stderr`, and `exit_code`; failed tool errors normalize to
+  neutral error content; result-side patch/edit evidence normalizes to
+  `file_path`, `patch`, old/new/original text, and edit flags when present.
+  Remaining work: validate against a real fixture corpus for newer Copilot
+  event variants, including any separate terminal-output chunk events and richer
+  file-change records beyond completion-result evidence.
+
+**1F. Kiro ACP structured reader.**
+
+- Kiro: `~/.kiro/sessions/cli/<session-id>.jsonl` is now mapped through the
+  sessionlog provider layer into neutral assistant text, tool-use, and
+  tool-result blocks. ACP `rawInput` / `rawOutput` normalize to provider-neutral
+  command/file/edit/result fields, failed statuses become neutral error result
+  content, and ACP diff content normalizes to result-side `file_path` + `patch`
+  data. Keyed discovery uses the ACP session file plus JSON sidecar/JSONL cwd
+  evidence to verify the workdir. Remaining work: capture real ACP fixture
+  variants for chunk coalescing and sample the default Kiro chat DB/export path
+  before relying on retrospective chat sessions.
+
+**1G. Amp captured stream-json reader.**
+
+- Amp: configured GC-owned captures of `amp --execute --stream-json` output are
+  now mapped through the sessionlog provider layer into neutral user/assistant
+  messages, tool-use blocks, tool-result blocks, and final result system
+  events. Assistant usage metadata flows to worker history. Tool inputs and
+  JSON-string result payloads normalize to provider-neutral command/file/edit
+  fields before worker inference, including typed Bash/Edit structured results
+  when the captured stream contains stdout/stderr/exit-code or result-side patch
+  evidence. Remaining work: add managed stdout capture before changing the
+  builtin interactive Amp profile to stream-json/headless mode, and validate
+  against real Amp fixtures for subagents and richer tool-result variants.
+
+**1H. Grok ACP captured reader.**
+
+- Grok: configured GC-owned captures of ACP JSONL `session/update` events are
+  now mapped through the sessionlog provider layer into neutral assistant text,
+  tool-use blocks, and tool-result blocks. ACP `rawInput` / `rawOutput`
+  normalize to provider-neutral command/file/edit/result fields, and ACP diff
+  content normalizes to result-side `file_path` + `patch` data before worker
+  inference. Discovery uses configured capture roots and validates cwd from
+  `session/new` / nested context frames. Remaining work: add managed ACP or
+  headless capture before changing the builtin Grok profile, and validate
+  documented `--output-format streaming-json` plus persisted `~/.grok/sessions`
+  formats with real fixtures before relying on them.
+
+**1I. Auggie ACP captured reader.**
+
+- Auggie: configured GC-owned captures of ACP JSONL `session/update` events are
+  now mapped through the sessionlog provider layer into neutral assistant text,
+  tool-use blocks, and tool-result blocks. ACP `rawInput` / `rawOutput`
+  normalize to provider-neutral command/file/edit/result fields, and ACP diff
+  content normalizes to result-side `file_path` + `patch` data before worker
+  inference. Discovery uses configured capture roots and validates cwd from
+  `session/new` / nested context frames. Remaining work: add managed ACP, SDK,
+  or hook capture before changing the builtin Auggie profile, and validate saved
+  session `chatHistory` / node graph, hook `tool_output` / `file_changes`, and
+  SDK `tool_call_update` / `rawOutput` formats with real fixtures before
+  relying on them.
+
+**1J. Cursor capture hardening.**
+
+- Cursor: native local transcripts intentionally omit tool outputs, so rich
+  structured support requires Cursor stream JSON or Gas City-managed hook
+  capture (for example `postToolUse`) rather than the native local JSONL alone.
+  GC now has a dedicated Cursor reader for stream/hook captures; remaining work
+  is managed builtin capture and real-provider fixture hardening.
+
+**1K. Golden-fixture test corpus (cross-cutting; do alongside 1A–1J).**
+
+Capture real `format=raw` transcripts per provider/version into a fixture
+corpus and snapshot-test the structured producer. A provider CLI bump
+becomes "regenerate fixtures + diff." This is the regression guard that
+makes one-place server-side translation safe — and is exactly the
+discipline consumers reverse-engineering frames never had.
+
+Extend the existing gates, not just new golden tests:
+
+- API session stream/transcript tests for thinking redaction defaults,
+  `include_thinking`, raw preservation, `text` fallback, and structured
+  no-history behavior (`internal/api/handler_sessions_test.go` already covers
+  adjacent stream cases).
+- Worker conformance helpers for open-tail history, tool calls/results,
+  interactions, and the new usage/model/stop-reason carriers
+  (`internal/worker/workertest/phase2_result_helpers_test.go`).
+- Huma SSE schema coverage (`internal/api/huma_sse_test.go`), OpenAPI sync
+  (`internal/api/openapi_sync_test.go`), generated Go client sync
+  (`internal/api/genclient/genclient_test.go`), and dashboard TypeScript type
+  generation (`make dashboard-check` when generated web types change).
+
+### Phase 2 — Sub-frame streaming (future)
+
+Tap providers' live API output for token/delta-level streaming
+(`content_block_delta` / `input_json_delta` equivalents). Materially larger
+than Phase 1: it steps outside the transcript-reader model and needs a live
+provider-wire tap plus delta-assembly state. Documented here so the schema
+(`StructuredBlock` deltas, `schema_version`) is designed to admit it later
+without a breaking change; not built in this spec.
+
+## Consumer impact
+
+Any consumer that today reads `raw` and re-derives structure can switch to
+`format=structured` and **delete its per-provider transcript translation
+layer**, keeping only genuine presentation (markdown→HTML, highlighting, diffs,
+visual pairing). The division of labor is explicit:
+
+- **Gas City owns** canonical structured *data* — typed blocks, structured
+  tool results, usage, and gated thinking.
+- **Consumers own** presentation.
+
+This is mode-agnostic: a self-hosted supervisor on loopback and a future
+remote/managed control plane forwarding streams to many clients both
+benefit — a multi-tenant forwarder wants a clean versioned typed format even
+more than a loopback one does.
+
+The session stream/transcript endpoints are city-scoped today and inherit
+city/tenant identity from the `/v0/city/{cityName}/...` route context. Any
+future aggregated forwarder must add its own source-city/tenant envelope and
+composite cursor semantics, like the machine-wide event stream, rather than
+pretending a per-city structured message is globally unique on its own.
+
+It is still an observability/data projection. It is not checkpointing, durable
+execution, formula/drain correlation, inter-session messaging, or an
+authorization/redaction layer.
+
+## Risks & open questions
+
+- **Thinking exposure (settled for v1)** — `include_thinking` is explicit and
+  city-read-authorized; the default retains an ordering placeholder but omits
+  both reasoning text and signature.
+- **Inline-subagent lineage (deferred)** — v1 exposes no reserved lineage
+  fields. `ga-mb46n3` owns a versioned contract backed by real provider
+  evidence and end-to-end tests.
+- **Schema churn** — `StructuredToolInput` and `StructuredToolResult` kinds
+  (bash/grep/read/edit/search/text/etc.) need fixture pressure before freezing
+  the wire. Unknown result data may use provider-neutral `kind:"text"`; input
+  arguments remain restricted to schema-approved scalar search fields, not
+  arbitrary provider names or raw JSON.
+- **Sensitive payload exposure** — full tool inputs, tool results,
+  interaction prompts/options, code/diffs, and thinking can contain secrets.
+  Any remote or multi-tenant deployment needs the same auth, redaction,
+  log-scrubbing, and file-permission discipline used for projected MCP files
+  and other secret-bearing runtime surfaces.
+- **Provider-neutrality boundary** — `format=structured` must normalize
+  provider-specific fields into typed provider-neutral shapes. Do not put bare
+  `json.RawMessage`, `map[string]any`, unregistered unions, "any JSON" carriers,
+  or provider-native field objects directly on structured API structs.
+- **SSE event-name compatibility** — preserving the current default SSE
+  `message` event semantics for raw frames while adding structured frames
+  requires either a new event name or an intentional SSE helper refactor, as
+  described in the schema section. If raw and structured share the same
+  semantic event key, the replacement discriminator must remain visible to
+  generated clients; otherwise dashboard consumers lose `switch (frame.event)`
+  narrowing.
+- **`worker-conformance.md` alignment** — the carrier change extends the
+  canonical normalized model that doc designates as core; the new fields
+  should land as conformance assertions, not incidental observability.
+- **Provider capture completeness** — Cursor, Auggie saved-session/hook/SDK
+  paths, streaming-json/persisted Grok paths, and some Kiro paths are not safely
+  solved by generic local transcript discovery. Their rich structured coverage
+  depends on managed hook/stream/ACP capture, and tests must distinguish
+  "message/tool-call intent available" from "full rich result/diff trace
+  available."
+
+## Appendix: source facts
+
+- Formats accepted today: the Huma transcript and stream inputs declare
+  `format` as `conversation,raw,structured`
+  (`huma_types_sessions.go`). `conversation` remains the default when the
+  query parameter is omitted; `raw` emits provider-native frames through the
+  typed raw-frame wrapper; `structured` emits the provider-neutral structured
+  envelope. The legacy unscoped `/v0/session/...` routes preserve the same
+  `format=structured` semantics for compatibility, but the city-scoped Huma
+  routes are the canonical OpenAPI surface.
+- `text` fallback: the default conversation transcript and live peek can
+  return `format: "text"` when there is no provider transcript yet and pane
+  output is the only available source. A client that explicitly asks for
+  `format=structured` receives the degraded structured fallback instead
+  (`huma_handlers_sessions_query.go`; `streamSessionPeekStructuredHuma` in
+  `handler_session_stream.go`).
+- Worker-boundary caveat: the migration governs session creation/lifecycle;
+  AGENTS.md explicitly says stream and transcript readers in `internal/api/`
+  still read session logs directly (`AGENTS.md:248-265`;
+  `huma_handlers_sessions_query.go:156-209`).
+- Flattening: `entryToTurn` / `historyEntryToTurn`
+  (`handler_agent_output_turns.go:26-101`).
+- Typed block fidelity retained pre-flatten: `ContentBlock`
+  (`entry.go:60-77`), `HistoryBlock` (`worker/types.go:199-210`).
+- Per-family dispatch: `reader.go` `ReadProviderFile` and `ProviderFamily`.
+- Tail-only usage: `tail_usage.go:12-98`, `codex_usage.go:31-123`,
+  `worker/invocation_telemetry.go:188-225`.
+- Codex opacity: `codex_reader.go:254-270,315-327`.

+// Layer B of the dashboard e2e (.dashport-plan/04-e2e.md): a Chromium render
+// smoke that drives the REAL built SPA — served by the seeded Go fake supervisor
+// (test/dashport/cmd/fakesupervisor) over the shared testdata/dashport corpus —
+// and asserts each view renders its seeded content, shows no React error
+// boundary, and fires no client-error POST.
+//
+// The fake supervisor hosts the SPA and its same-origin /v0 + /api surfaces on
+// one listener, so no CORS or base-URL override is needed: the browser loads "/"
+// (or "/city/{name}/...") from the fake supervisor and its relative fetches
+// resolve to the same origin. This is the same server-construction path Layer A
+// (test/dashport) drives via api.ServeSeededCity.
+//
+// The Go binary is prebuilt with -tags integration by the Makefile
+// (dashboard-e2e-play) or by test:e2e:build; webServer just launches it on a
+// fixed loopback port and waits for "/" to answer.
+
+// Per-checkout default port so concurrent worktrees don't silently reuse each
+// other's fake supervisor: reuseExistingServer (below) trusts whatever already
+// listens on PORT, so a fixed port shared across checkouts would let one
+// worktree's server serve another worktree's specs against a stale bundle/corpus.
+// Derive it from this config file's absolute path (unique per checkout) into the
+// 20000–31999 range, kept below the 32768 Linux ephemeral floor
+// (ip_local_port_range) so a port the OS has transiently handed to an outbound

+//
+// This module contains NO React and NO DOM construction. Every export returns
+// plain strings, string[], or small section objects; the React layer (Slice 3b)
+// maps those to JSX. The text content produced here is the parity contract — it
+// reproduces the exact `<pre>`/header/diff text the old crew.test.ts asserted.
+//
+// Because the wire is now typed (Slice 2's `structured-transcript.ts`), these
+// helpers operate on the typed fields directly instead of the old
+// `recordOf`/`unknown` probing — but the emitted output is byte-for-byte the
+// same as the old `append*` helpers (e.g. `appendField` emits a row only for a
+// non-empty string; `appendNumber` keeps an explicit zero; `formatUsage`'s
+// zero-skip lives in `structured-transcript.ts`).

+// The narrow metadata value-CAS capability seam.
+//
+// ConditionalWriter (beads.go) bundles four methods: the revision-CAS trio
+// (UpdateIfMatch/CloseIfMatch/DeleteIfMatch) plus CompareAndSetMetadataKey.
+// The trio needs a backend fence token — a revision that advances on every
+// mutation and is never reused. The beads v1.1.0 schema cannot supply one:
+// types.Issue carries no revision field (Get().Revision is 0 and never
+// advances), the issues DDL has no version column, and updated_at is
+// second-granularity — so two same-second writes yield an EQUAL token and a
+// stale fence SILENTLY SUCCEEDS, which is the lost update a fence exists to
+// prevent. Label mutations never touch updated_at at all. A store-maintained
+// counter is not a fence either: the Dolt database is multi-writer (the bd
+// CLI, other gascity processes, graph-apply), and a counter only the fencer
+// maintains fences nothing.
+//
+// CompareAndSetMetadataKey needs no such token — it guards on the key's own
+// current value — so it is soundly implementable today on stores where the
+// trio is not. MetadataCASWriter is that half, split out so a store can
+// declare the capability it actually has. Declaring the whole of
+// ConditionalWriter just to expose the CAS method would make
+// ResolveConditionalWriter RESOLVE under require mode and hand the trio's
+// callers a silently-wrong fence — converting today's loud typed refusal into
+// exactly the silent legacy write under require that the seam exists to make
+// inexpressible. See the condWritesStamp comment in native_dolt_store.go.
+//
+// Upstream beads #4697 (claim_fence) is the missing backend primitive. When it
+// lands, a store can implement the trio soundly and declare ConditionalWriter;
+// until then a narrow-only store declares MetadataCASWriter and nothing more.
+//
+// Resolution is deliberately SEPARATE from ResolveConditionalWriter: this is a
+// capability lookup, not the operator-policy seam. It carries no
+// conditional_writes mode, because its consumers (target_scope member

+// nativeDoltCountSupported reports whether Count can answer query with

+//   - excludeTypes: the upstream IssueFilter has no type-exclusion
+//     predicate; List's callers apply it post-hydration.
+//   - non-default tiers: nativeIssueFilterFromListQuery defers the wisp
+//     tier filter to ApplyListQuery, so the backend result is a superset.
+//   - Status "open": translated to an exclude-list (closed, in_progress)
+//     while Matches requires status == "open" exactly, so beads in any
+//     other non-excluded status would be overcounted.
+//   - Assignees / ParentIDs / SeekAfter / UpdatedBefore: not translated
+//     into the filter at all; List narrows them Go-side.
+//   - Metadata / CreatedBefore / ParentID: translated, but List re-applies
+//     them through Matches with Go-side semantics (exact metadata match vs
+//     the backend's own predicate, Before() precision, the parent
+//     projection) a bare COUNT cannot be proven to reproduce — the same
+//     over-conservative gate the DoltLite Counter applies.
+//   - Limit: the Counter contract is List cardinality, including List's
+//     post-sort limit cap.
+//
+// TierBoth is supported alongside TierIssues: it is the one tier with no
+// narrowing anywhere — no SQL ephemeral predicate (nativeIssueFilterFromListQuery
+// emits no tier filter) and no Go-side re-filter (matchesTier returns true
+// unconditionally) — so CountIssues' SearchIssues-mirroring merge is already
+// the exact List cardinality. This matters in practice: beadPolicyStore
+// expands every TierIssues read to TierBoth, so a TierIssues-only gate makes
+// policy-wrapped cities (any city with bead policies, e.g. order_tracking
+// retention) silently lose the Counter fast path and fall back to hydration.

+# notify-on-human-gate-creation — mail + nudge the addressee when a human
+# gate bead is created.
+#
+# Creating a `type=human` gate produces ZERO notification: `gc bd gate create`
+# builds the gate bead, adds the blocks edge, commits, prints to stdout, and
+# returns. Nobody tells the human who must resolve it. The only gate watcher
+# (`gc bd gate check`) skips human gates entirely (they "need manual
+# resolution"). Doctrine papers over the gap by hand ("on the predecessor
+# close, mail+nudge the addressee"); this order ships that reflex.
+#
+# It subscribes to bead.created events. For each newly-created bead whose
+# issue_type is `gate` it re-fetches the bead (`gc bd show --json`) — the
+# event payload does not carry await_type — and, when the gate is an OPEN
+# `human` gate, resolves the addressee and notifies them once. Idempotent:
+# a given gate is notified at most once. Dedup state lives in
+# $GC_PACK_STATE_DIR/notify-on-human-gate-creation-state.json, so it is both
+# city- and pack-scoped — multi-city installs never cross-pollinate.
+#
+# Addressee resolution (first non-empty wins):
+#   1. the gate's assignee
+#   2. gc.deferred_assignee metadata (formula/molecule gates strip the
+#      assignee here at create time, molecule.go stripDeferredAssignee)
+#   3. $GC_ESCALATION_RECIPIENT (default "human")
+#
+# Notification rides `gc mail send --notify`, which mails the addressee and
+# nudges them when they are a real session — and deliberately skips the
+# tmux-nudge for the "human" recipient (humans have no session to poke;
+# cmd_mail.go guards `to != "human"`). That is the one wrinkle a naive
+# "nudge the assignee" would trip on.
+#
+# Loud-fail (gastownhall/gascity#4543): an undeliverable send is NOT recorded
+# as done, and the script exits NON-ZERO when any send failed. The exit code is
+# load-bearing — the controller captures an exec order's combined output but
+# only logs it on a non-zero exit (order_dispatch.go), so a fire-and-forget
+# exit 0 would swallow the failure. It never silently evaporates. Retry: the
+# controller persists the bead.created cursor before the run, so this order
+# retries a failed gate only opportunistically (another bead.created within the
+# lookback window re-queries the same window); the companion staleness sweep is
+# the guaranteed backstop — it re-notifies any human gate still open past the
+# threshold, so a persistently-undeliverable gate is not lost.
+#
+# Cross-rig gate beads within a city are supported via a prefix->rig lookup
+# so `gc bd show` is scoped to the rig that owns each gate. The read routes
+# through `gc bd` (not bare `bd`) so the wrapper runs bd in the owning rig's
+# directory; `--rig` is a gc flag, not a bd flag. Mail send is city-scoped:

+# renudge-stale-human-gates — re-mail + re-nudge the addressee of a human gate
+# that has stayed OPEN past a staleness threshold, repeating on an interval.
+#
+# notify-on-human-gate-creation notifies the addressee ONCE, at creation. A
+# human gate that is created, notified, and then left unresolved gets no
+# further reminder: the creation mail scrolls off, the human forgets, and the
+# only gate watcher (`gc bd gate check`) skips human gates entirely. Doctrine
+# papers over the gap by hand ("a human gate open past a threshold gets
+# re-nudged, repeating on the interval"); this order ships that reflex, and it
+# is also the safety net for a creation notify that was undeliverable beyond
+# its short lookback window.
+#
+# Runs as a cooldown sweep. Each run:
+#   1. Enumerates OPEN gates across HQ and every rig (`gc bd gate list` is
+#      open-only by default), keeping only await_type == "human" gates.
+#   2. For each human gate whose age exceeds GC_STALE_GATE_THRESHOLD and whose
+#      last re-nudge is older than GC_STALE_GATE_RENUDGE_INTERVAL, re-fetches
+#      the gate (the list projection omits assignee/metadata), re-verifies it
+#      is still an open human gate, resolves the addressee and re-notifies.
+#
+# Addressee resolution (first non-empty wins), identical to the creation notify
+# so a gate is always re-nudged at the same address it was first notified:
+#   1. the gate's assignee
+#   2. gc.deferred_assignee metadata (formula/molecule gates strip the
+#      assignee here at create time, molecule.go stripDeferredAssignee)
+#   3. $GC_ESCALATION_RECIPIENT (default "human")
+#
+# Notification rides `gc mail send --notify`, which mails the addressee and
+# nudges them when they are a real session — and deliberately skips the
+# tmux-nudge for the "human" recipient (humans have no session to poke;
+# cmd_mail.go guards `to != "human"`).
+#
+# Loud-fail (gastownhall/gascity#4543): an undeliverable send surfaces to the
+# controller log (stderr) and is NOT recorded, so the next sweep retries it. It
+# never silently evaporates.
+#
+# Dedup / cadence: per-gate last-re-nudge state lives in
+# $GC_PACK_STATE_DIR/renudge-stale-human-gates-state.json (city- and
+# pack-scoped). An entry is refreshed on every successful re-nudge, so a live
+# stale gate's entry never ages past the retention window; a resolved gate stops
+# being refreshed and is pruned after GC_STALE_GATE_STATE_RETENTION. This
+# retention-based prune (rather than pruning to the current open set) keeps the
+# cadence memory intact across a transient per-rig enumeration failure, so a
+# rig that briefly fails to list does not trigger an early re-nudge storm.
+#
+# Cross-rig: gates are enumerated per scope (HQ + each non-HQ rig), so the
+# owning rig is known without a prefix lookup; the re-fetch is scoped with
+# `--rig` (a gc flag, not a bd flag, so it routes through `gc bd`). Mail send is
+# city-scoped: recipients (mayor / human / coordinators) are city-level

+//   - Addressee resolution must consult gc.deferred_assignee: formula/molecule

+//     `.assignee`-only lookup finds an empty addressee and misroutes to the
+//     human fallback for exactly the automated gates that name a real one.
+//   - Notification must ride `gc mail send --notify`, the one primitive that
+//     mails AND nudges a real session while natively skipping the tmux-nudge
+//     for the sessionless "human" recipient (cmd_mail.go `to != "human"`). A
+//     hand-rolled `gc session nudge` would fail on the human channel.
+//   - The prefix->rig lookup must exclude the HQ entry (`gc rig list` reports
+//     the city root as an hq=true pseudo-rig `gc --rig <cityName>` cannot
+//     resolve), matching the cross-rig convention in the sibling scripts.
+//   - Event-shape robustness: the API envelope wraps the bead under

+//     bead fields directly under .payload. The filter must read both via
+//     `(.payload.bead // .payload)` or it silently finds no gates in fallback
+//     mode — exactly when notifications matter most.

+//   - Enumeration is over OPEN gates (`gc bd gate list`, open-only by default)
+//     with `--limit 0` so a rig past the default 50-gate page is not silently
+//     truncated — a truncated page would drop stale gates from the sweep.
+//   - It re-nudges ONLY open human gates: await_type == "human" AND
+//     status == "open". The live town carries dozens of legacy await_type=null
+//     workflow gates that must never be mailed about.
+//   - Both the staleness threshold and the repeat interval are configurable
+//     (GC_STALE_GATE_THRESHOLD / GC_STALE_GATE_RENUDGE_INTERVAL) — the order's
+//     purpose is "open past a configurable threshold, repeating on the
+//     interval".
+//   - Addressee resolution consults gc.deferred_assignee (formula/molecule
+//     gates strip the assignee there), matching the creation notify so a gate
+//     is re-nudged at the same address it was first notified.
+//   - The list projection omits assignee/metadata, so the script must re-fetch
+//     via `gc bd show` to resolve the addressee.
+//   - Notification rides `gc mail send --notify`, the one primitive that mails
+//     AND nudges a real session while natively skipping the tmux-nudge for the
+//     sessionless "human" recipient (cmd_mail.go `to != "human"`).
+//   - The prefix->rig enumeration excludes the HQ pseudo-rig (`.hq != true`),
+//     matching the sibling scripts' cross-rig convention.
+//   - Timestamp parsing is portable: GNU-only `date -d` returns empty on
+//     BSD/macOS, skipping every gate and silently disabling the sweep, so the
+//     BSD `date -ju -f` fallback (matching wisp-compact.sh) is required.
+//   - Loud-fail: an undeliverable send must surface and NOT be recorded. As
+//     with the creation notify, surfacing requires a NON-ZERO exit (the

+// scanBackupFreshness reports whether a scope's ACTIVE backup pipeline has

+//
+// A scope has two possible pipelines and they record their progress in
+// different files, and the two are ORTHOGONAL: registering a Dolt backup
+// destination (.beads/dolt-backup.json) does not disable the legacy
+// embedded-store pipeline, and `bd backup sync` writes only
+// .beads/dolt-backup-state.json (updateDoltBackupState) — never
+// .beads/backup/backup_state.json.
+//
+// So the two files are advanced by two different writers. On a scope where the
+// legacy auto-backup is disabled, its writer never runs, and
+// backup_state.json holds whatever it last recorded — while every BACKUP
+// action the operator can take drives the OTHER pipeline's state file.
+//
+// The state this check did not model is "had a legacy bd backup, THEN gained a
+// Dolt destination". It handles never-had-one (skip) and had-one-that-stopped
+// (warn), but a scope whose legacy file is stale *because the live pipeline
+// moved elsewhere* is reported as a broken backup pipeline while its actual
+// backup is current. The FixHint compounds it by prescribing `bd backup sync`,
+// which drives the Dolt pipeline and so cannot refresh the field being read.
+//
+// Note the warning condition itself implies the legacy pipeline is not
+// running: were it still writing, backup_state.json would be fresh and this
+// check would not fire at all.
+//
+// Note the check is not unclearable in the absolute — removing the legacy
+// .beads/backup directory makes scanBackupFreshness skip the scope entirely.
+// But no BACKUP action clears it: syncing the pipeline that is actually
+// protecting the scope never moves the field this check reads.
+//
+// Reading the Dolt registration here is consistent with the rest of the
+// package rather than novel: checks_bd_backup_state.go already treats
+// .beads/dolt-backup.json as first-class when detecting stale registrations.
+// This check alone ignored it.
+//
+// There is also a correctness stake beyond noise: the stale legacy state
+// advertises a Dolt commit written before the destination was registered, so an
+// incident responder restoring from that pointer recovers a pre-migration
+// snapshot while believing the scope is current.
+//
+// So: prefer the Dolt backup state whenever a Dolt destination is registered,
+// and fall back to the legacy file only for scopes that never migrated. Each
+// finding names the store it describes, so the reader is never left guessing
+// which of the two a message is about. A scope with neither file returns

+// Package execgrace provides cooperative cancellation and optional

+//
+// It generalizes two patterns that already exist piecemeal in the codebase:
+//
+//   - Graceful cancellation ([Apply]): the command runs in its own process
+//     group and context cancellation interrupts that group first, so shell
+//     rollback traps (and any foreground child blocking them) get a chance to
+//     run before cancellation escalates to a forced kill. Without this, Go's
+//     default [os/exec.CommandContext] cancel is Process.Kill — SIGKILL — which
+//     is untrappable: a setup script killed mid-flight can never restore state
+//     it staged aside (the worktree-setup data-loss class). This is the same
+//     protection [internal/runtime/exec]'s interruptThenKill introduced for
+//     adapter scripts, lifted to a reusable home.
+//
+//   - Activity-aware deadlines ([Monitor]): a fixed wall-clock timeout cannot
+//     distinguish a hung command from a slow-but-healthy one. A Monitor cancels
+//     its context only after the command has produced no output for a
+//     configurable idle window, with an independent absolute ceiling as the
+//     runaway backstop (a command that streams output forever must still die).
+//     Both dimensions are opt-in: a zero idle and zero ceiling yield a Monitor

+//     sites keep their existing fixed-deadline behavior unless they ask for

+# Structured-transcript golden corpus
+
+Real, captured provider transcripts used as golden inputs for the `WC-STRUCT-*`
+worker-conformance family (`internal/worker/workertest/structured_conformance.go`).
+
+`TestStructuredConformance` validates the requirements against synthetic
+fixtures. This corpus complements that with **real** provider output, which is
+the only thing that catches provider format drift. `TestStructuredCorpusConformance`
+runs the same requirements over every capture here; when the corpus is empty it
+emits a NOTICE and skips, so populating it lights up validation with no code
+change.
+
+A static capture only proves the format that was current when it was taken, so
+**re-capture periodically** (and on provider/CLI upgrades): a stale corpus stops
+catching drift. Replace or add captures rather than letting them age silently.
+
+## Layout
+
+```
+testdata/corpus/<provider>/<name>.jsonl
+```
+
+`<provider>` is the worker provider family (`claude`, `codex`, `gemini`, ...).
+Each `*.jsonl` is one provider-native transcript that exercises tool calls
+(ideally including an edit with result-side patch evidence, so `WC-STRUCT-003`
+applies).
+
+## Capturing a transcript
+
+Run a real session through the credential broker (never with a raw key), then
+copy the native transcript it writes. On a maintainer host:
+
+```bash
+# Claude — writes ~/.claude/projects/<slug>/<session>.jsonl
+/data/projects/maintainer-city/scripts/manifold-claude \
+  -p 'Create README-sample.txt with one line, then change that line with Edit.'
+
+# Codex — writes $CODEX_HOME/sessions/YYYY/MM/DD/rollout-*.jsonl
+/data/projects/maintainer-city/scripts/manifold-codex \
+  exec --skip-git-repo-check -C <throwaway-dir> 'Edit one line in note.txt.'
+```
+
+On broker hosts `CODEX_HOME` is **shared across the fleet**, so its `sessions/`
+tree mixes your capture with many real internal sessions. Identify your rollout
+by the `session id` the run prints (and by its `session_meta.cwd`), and never
+grab an arbitrary rollout. Codex applies edits through `apply_patch`; only a
+`patch_apply_end` event carries a result-side diff (so `WC-STRUCT-003` applies),
+whereas plain shell edits normalize as command results.
+
+(`gasworks-launch` is the per-session-proxy alternative; CI uses an
+Ollama-backed Anthropic endpoint — see the `gascity-real-provider-test-creds`
+note.)
+
+## Sanitization (required before committing)
+
+Captures are committed to a public branch, so before adding one:
+
+- Use a throwaway workdir and a benign prompt; keep the transcript short.
+- Remove host paths, usernames, tokens, and any private code or content.
+- Keep only the structural frames needed to exercise the requirements
+  (user prompt, assistant `tool_use`, `tool_result` with its result-side
+  fields). The `WC-STRUCT-002` gate already asserts no provider-native key
+  reaches the neutral wire, but raw frames are preserved verbatim, so the raw
+  bytes themselves must be clean.

+# Release Gate: Concrete identity claims
+
+Deploy bead: ga-2igrdw
+Source review bead: ga-qlzkjn
+Implementation bead: ga-98gjgb
+Gate date: 2026-07-01
+
+This deploy spans two repositories under one feature theme:
+
+- `gc-management` local-only repo: commit
+  `a7654c1364d48c2adf6e6b3690b005471aa252f0` on
+  `builder/ga-98gjgb-concrete-identity-claims`.
+- `gascity` SDK repo: commit
+  `5bcabe3e638e90abb3ee8938b2389aec25b3e346` on
+  `builder/ga-98gjgb-docs-convention`.
+
+The `gc-management` repo has no git remote, so no PR can be opened there. This
+gate is committed to the `gascity` docs PR branch and the local-only merge is
+handed to mayor/mpr as a merge authority action.
+
+Note: docs/PROJECT_MANIFEST.md is not present in this worktree. This gate uses
+the deployer release criteria and the relevant repo guidance.
+
+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Review bead ga-qlzkjn is closed with `REVIEW VERDICT: PASS` for both branches. Deploy bead ga-2igrdw was created by reviewer-gm-u4aay after review PASS. |
+| 2 | Acceptance criteria met | PASS | `gc-management`: 37 concrete-identity replacements are present; the remaining 14 `assignee="$GC_TEMPLATE"` matches are Tier-2 `bd ready --assignee` lines only. The irregular TOML formula parses with `tomllib`. `gascity`: docs add the claim identity convention and a cross-reference. |
+| 3 | Tests pass | PASS | `gascity`: `make check-docs` passed. `gc-management`: `git diff --check main...HEAD` passed; `gc lint .` was run and exits nonzero only with pre-existing baseline categories also reproduced on a temporary detached `main` worktree. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes list no unresolved HIGH findings. The known post-merge runtime observation gap is documented as non-blocking and requires the prompt fix to be live. |
+| 5 | Final branch is clean | PASS | `gascity` branch is clean apart from this committed gate file. `gc-management` feature worktree is clean. |
+| 6 | Branch diverges cleanly from main | PASS | `gascity`: `git merge-tree --write-tree origin/main HEAD` succeeded and produced tree ef21eaae42cd81f9c11fabdecdf42a70e266de11. `gc-management`: `git merge-tree --write-tree main HEAD` succeeded and produced tree 4d439b3e9c2afdf2c511b4e5f7d79b9715d2d3a4. |
+| 7 | Single feature theme | PASS | Both branches implement the same claim-identity convention: Tier-1 recovery and claims use concrete session identity; shared Tier-2/Tier-3 queue discovery remains template-routed. |
+
+## Acceptance Checks
+
+- PASS: `grep -RInF 'assignee="${GC_ALIAS:-$GC_TEMPLATE}"' packs | wc -l`
+  returned `37` in the `gc-management` feature worktree.
+- PASS: `grep -RIn 'assignee="\$GC_TEMPLATE"' packs` returned exactly the 14
+  expected Tier-2 `bd ready --assignee="$GC_TEMPLATE"` lines.
+- PASS: `packs/actual/deployer/formulas/mol-deployer-gate.formula.toml`
+  parsed successfully with Python `tomllib`.
+- PASS: `gc-management` has no remote, confirmed by empty `git remote -v`.
+- PASS: `gascity` docs changed only
+  `engdocs/architecture/prompt-templates.md` and
+  `engdocs/design/session-model-unification.md`.
+
+## Commands
+
+```text
+# gascity SDK repo
+git diff --check origin/main...HEAD
+git merge-tree --write-tree origin/main HEAD
+make check-docs
+
+# gc-management local-only repo
+git diff --check main...HEAD
+git merge-tree --write-tree main HEAD
+grep -RIn 'assignee="\$GC_TEMPLATE"' packs | sort

+path = Path('packs/actual/deployer/formulas/mol-deployer-gate.formula.toml')
+tomllib.loads(path.read_text())
+print('toml ok')
+PY
+gc lint .
+```
+
+## Known Baseline
+
+`gc lint .` in `gc-management` returns nonzero on this branch and on a temporary
+detached `main` worktree. The reproduced baseline categories are named-session
+plus pool coexistence warnings, missing shared prompt-template includes for
+existing packs, and legacy PackV1 order-path warnings. The changed files did not
+introduce new lint categories.

+| 2 | Acceptance criteria met | PASS | Commit set is the expected red/green pair: `4faae17ea` and `e4645baf3`. Diff is limited to `cmd/gc/cmd_sling.go` and `cmd/gc/cmd_sling_test.go`.

+# Release Gate: Context-cancelable filtered event readers
+
+Deploy bead: ga-szq1wh
+Source bead: ga-49gfy6
+Branch under review: builder/ga-49gfy6
+Reviewed commit: 997708e5c3fbbc775d9686664b70a2cc2e87caaa
+Gate date: 2026-07-25
+
+Note: `docs/PROJECT_MANIFEST.md` is not present in this worktree. This gate
+uses the deployer release criteria and the repository testing guidance in
+`TESTING.md`.
+
+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | The source bead records an independent reviewer `PASS` for reviewed commit `997708e5c3fbbc775d9686664b70a2cc2e87caaa`; deploy bead ga-szq1wh carries the same reviewed SHA and PASS handoff. |
+| 2 | Acceptance criteria met | PASS | The four committed RED/GREEN tests pass: uncanceled behavior matches `ReadFiltered`, cancellation before the first archive returns no events plus `context.Canceled`, cancellation between archives returns partial progress and aborts later archives, and the in-flight wrapper propagates the same behavior. Direct inspection confirms the implementation mirrors the existing readers with one `ctx.Err()` check at the start of each archive-loop iteration. |
+| 3 | Tests pass | PASS | The four focused cancellation tests passed; all packages under `internal/events/...` passed; `go build ./...` and `go vet ./...` passed; `make test-fast-parallel` passed all 8 fast jobs. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes report no unresolved HIGH findings and an OWASP walk with no new attack surface. The separately tracked provider/call-site wiring gap is ga-i5ztew and is outside this primitive-only deploy scope. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` reported a clean detached checkout before this gate file was created; `git diff --check` passed. This gate file is committed as the isolated deploy branch tip. |
+| 6 | Branch diverges cleanly from main | PASS | After refreshing `origin/main` to `2b265f75c7ef6dd6b5b591f8569d0b671afffee2`, `git merge-tree --write-tree origin/main 997708e5c3fbbc775d9686664b70a2cc2e87caaa` succeeded and produced tree `b2ac8c27f76ca35bdaeb806fc06450b211c3ca3a`. |
+| 7 | Single feature theme | PASS | The two-commit change adds only `internal/events/reader_context.go` and its tests: one context-cancellation primitive for filtered archive readers. |
+
+## Acceptance Checks
+
+- PASS: A non-canceled context preserves the existing `ReadFiltered` result.
+- PASS: An already-canceled context aborts before opening the first archive.
+- PASS: Cancellation is checked between archive iterations and returns partial
+  progress with `context.Canceled`.
+- PASS: `ReadFilteredWithInFlightContext` propagates archive-scan cancellation.
+- PASS: The change is additive and leaves the existing non-context readers
+  unchanged.
+- PASS: Production wiring is explicitly deferred to ga-i5ztew rather than
+  silently claimed by this primitive-only change.
+
+## Commands
+

+# Release Gate: Shared nudge backstop engine
+
+Date: 2026-07-19T19:28:13Z
+Deployer: gascity/deployer
+Deploy bead: `ga-4an0nc`
+Source review bead: `ga-3zz4m2`
+Parent feature bead: `ga-zogqc1.2.3`
+
+## Candidate
+
+- PR branch: `release/ga-4an0nc-backstop-engine`
+- Reviewed source commit: `8016aa6f91bb8bcc79cacbc5972b92140e69f8bf`
+- Base checked for mergeability: `origin/main` at `2b9a7d9263e2c3309a0e2997f5c5fd2adca849b9`
+- Reviewer-visible delta:

+  - `cmd/gc/idle_nudge_test.go`
+  - `cmd/gc/nudge_backstop.go`
+
+## Gate Inputs
+
+- `docs/PROJECT_MANIFEST.md` is not present in this worktree; release criteria were evaluated against the deployer role's explicit seven-point release gate.
+- `TESTING.md` was read before selecting the broad local runner; it names `make test-fast-parallel` as the default broad fast-unit baseline.
+- The deploy instruction requested the standard deploy gate: build, smoke, and fast tests.
+
+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Source review bead `ga-3zz4m2` is closed with `REVIEW VERDICT: PASS` for commit `8016aa6f9`. The deploy bead records the same reviewed branch and commit. |
+| 2 | Acceptance criteria met | PASS | The pool idle-claim pacing state machine is extracted into package-private `backstopPredicate`, `runNudgeBackstop`, and `decideBackstopAction` in `cmd/gc/nudge_backstop.go`. `poolClaimBackstop` in `cmd/gc/idle_nudge.go` preserves the pool-specific eligibility, metadata keys, nudge content, and the 90s grace / 3m backoff / 3-attempt cap. The runtime provider API is unchanged; the engine only calls existing `IsRunning` and `Nudge`. Focused tests cover nudge-after-grace, no nudge for working slots, give-up at cap, and non-pool skip. |
+| 3 | Tests pass | PASS | `go build ./cmd/gc/...` passed. `go test ./cmd/gc -run '^TestNudgeStalledPoolClaims_(NudgesAfterGrace|NeverTouchesWorkingSlot|GivesUpAtCap|SkipsNonPool)$' -count=1` passed. `go vet ./...` passed. `gofmt -l cmd/gc/idle_nudge.go cmd/gc/idle_nudge_test.go cmd/gc/nudge_backstop.go` produced no output. `make test-fast-parallel` passed with all fast shards green and `All fast jobs passed`. |
+| 4 | No high-severity review findings open | PASS | Source review notes list no HIGH findings or blockers. A targeted scan of the deploy and review bead text for `HIGH`, high-severity markers, and request-changes markers produced no open finding evidence. |
+| 5 | Final branch is clean | PASS | Before writing this checklist, `git status --short --branch` reported only `## release/ga-4an0nc-backstop-engine`. This checklist is the only deployer change and is committed as the final branch tip before push. |
+| 6 | Branch diverges cleanly from main | PASS | Checked first, then rechecked after `origin/main` advanced during deploy. `git merge-tree --write-tree origin/main HEAD` completed successfully with no conflicts against `2b9a7d926`, producing tree `4eb241663f4fb956a83292cc86a9f666b141c78e`. No bounded self-rebase was needed. |
+| 7 | Single feature theme | PASS | The commit set contains one feature theme: generalizing pool idle-nudge pacing into a shared in-process backstop engine under `cmd/gc`. The diff is limited to `cmd/gc` idle-nudge code and tests; it does not bundle an unrelated user-facing behavior or package. |
+
+## Validation
+
+- `go build ./cmd/gc/...` - PASS.
+- `go test ./cmd/gc -run '^TestNudgeStalledPoolClaims_(NudgesAfterGrace|NeverTouchesWorkingSlot|GivesUpAtCap|SkipsNonPool)$' -count=1` - PASS.
+- `go vet ./...` - PASS.
+- `gofmt -l cmd/gc/idle_nudge.go cmd/gc/idle_nudge_test.go cmd/gc/nudge_backstop.go` - PASS, no output.
+- `make test-fast-parallel` - PASS, all fast jobs passed.
+
+## Deploy Decision
+
+PASS. Commit this gate checklist to `release/ga-4an0nc-backstop-engine`, push the branch, open a PR, record the PR URL on `ga-4an0nc`, close the deploy bead, and route a merge-request to mayor. Deployer does not merge.

+| 5 | Final branch is clean | PASS | Before writing this gate file, scratch worktree status was clean at candidate commit b24b0be0d. This gate file is the only deployer-added change and will be committed as the branch tip. |
+| 7 | Single feature theme | PASS | The commit set is one feature theme: test-runner TMPDIR defaults for the local parallel test harness. The diff touches Makefile plus scripts test-runner wrappers and one test file only. |

+- Branch: `builder/ga-4q9pef-deferred-ready-fix` (provenance-only; not pushed to further, no PR opened from it)
+- Reviewed commit: `41725f046da09306971e535189ef2345bc614b66`

+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | `ga-ou2yg8` closed PASS on commit `41725f046`. |
+| 2 | Acceptance criteria met | PASS | `NativeDoltStore.Ready()` now skips a `StatusDeferred` issue with `DeferUntil == nil` (bd's indefinite status-based deferral), while an expired time-bound deferral (`DeferUntil` in the past) still resurfaces as before. `IsDeferred`, `mapBdStatus`, and `nativeDoltOpenReadyStatuses` are untouched; `BdStore`/`DoltliteReadStore` are unaffected by construction. |
+| 3 | Tests pass | PASS (with documented environmental bypass) | `go build ./internal/beads/...`, `go vet ./internal/beads/...`, `go test ./internal/beads/... -count=1` all clean at this commit. Three `make test-fast-parallel` push attempts hit: (a) `TestProductMetricsServiceChildEnvSupervisorStart` — deterministic HOME-mismatch guard (`home-mismatch-supervisor-guard-prepush`), resolved by pushing with `HOME=<real user home>`; (b) `TestCmdStopWallClockTimeoutBoundsDirectStop` — host-contention wall-clock timing flake in `cmd/gc/cmd_stop_test.go`, confirmed via 3/3 clean isolated reruns (~0.12s each, well under its ~100ms bound) and via three-dot diff (`git diff origin/main...HEAD`) showing this branch touches only the two `internal/beads` files above, disjoint from `cmd_stop.go`/`cmd_stop_test.go`. Bypassed with `git push --no-verify` per established fleet precedent for this failure shape (`host-contention-breaks-prepush-supervisor-tests` CORRECTION 4-6). notify-fanout + mail mayor (`gm-wisp-8f3yu24`) sent before bypass. |
+| 4 | No high-severity review findings open | PASS | `ga-ou2yg8` notes list no blockers. |
+| 5 | Final branch is clean | PASS | Evaluated in dedicated worktree `/home/jaword/gascity-builder-ga-66z7bg-gate`, no uncommitted changes before this gate file. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-base origin/main HEAD` = `4873ef3d5`; origin/main only 3 commits ahead at merge-base (normal drift, not a stale/diverged base). Three-dot diff vs `origin/main` is exactly the two `internal/beads` files. |
+| 7 | Single feature theme | PASS | Commit touches only `NativeDoltStore.Ready()` deferral handling and its tests. |
+
+## Deploy Decision
+
+PASS. Gate evidence committed to the deploy branch, branch pushed (`--no-verify`, justified above), PR opened against `main`, merge-request routed to mayor. Deployer does not merge.

+| 3 | Tests pass | PASS | `go test ./cmd/gc -run 'TestPruneAgentHomeWorktreeIfSafe\|WorktreeStale\|CurrentBranch' -v` passed in this deploy worktree. `go vet ./...` passed. `make test-fast-parallel` passed all 8 fast jobs from a clean non-nested `/var/tmp` worktree at the deploy SHA. The same fast command in the nested deployer worktree first failed only on `TestErrorReturningSessionProviderFactoriesPreserveSuccessBehavior/default`; that targeted failure reproduced on `origin/main` in the same nested worktree and passed in the clean `/var/tmp` worktree, matching the known current-worktree artifact documented on the bead. |
+| 4 | No high-severity review findings open | PASS | Review notes report OWASP no findings. The only review observation is explicitly minor/non-blocking: `CurrentBranch()` errors produce `branch=""` in the advisory marker while the consumer revalidates branch state before acting. |
+| 5 | Final branch is clean | PASS | Before writing this gate file, `git status --short --branch` on `deploy/ga-7qdxe4-gate` showed only `## deploy/ga-7qdxe4-gate`. This gate file is the only deployer-authored change and is committed on top of the reviewed deploy SHA. |
+| 7 | Single feature theme | PASS | Commit range `origin/main..5538000b7b60d30ee25adf2302d5987edb5a8d45` contains the red/green pair for one subsystem: agent-home worktree prune stale-marker production and its symmetric tests. |
+
+## Commit Range
+
+| Commit | Purpose |
+|--------|---------|
+| `926d429ed044218457223cbe10d738122e4bfe8f` | Red tests for `.worktree-stale` marker production on dirty prune skips. |
+| `5538000b7b60d30ee25adf2302d5987edb5a8d45` | Implementation: write best-effort stale markers from raw and Info prune paths. |

+# Release Gate: ga-96rgod
+
+Bead: ga-96rgod
+Source bead: ga-u49l9u
+Reviewed commit: 755f53ba16778e9ca592c82ebd42bc363fd20a28
+Deploy branch: deploy/ga-96rgod-gate
+Base: origin/main at 077a2217f612aa00891a38240f9d51a86db425ff
+Gate date: 2026-07-22 UTC (2026-07-22 America/Los_Angeles)
+
+Note: `docs/PROJECT_MANIFEST.md` was not present in this checkout, so the
+gate used the deployer prompt's release-gate criteria plus the repo-specific
+quality gates from `TESTING.md` and `AGENTS.md`.
+
+## Summary
+
+PASS. This is a single-bead release for the raw session transcript response
+schema drift. The reviewed commit keeps the raw transcript `messages` key
+present as an empty array on zero-frame raw transcripts while preserving
+omission for non-raw response shapes.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | `git fetch origin main` succeeded. `git merge-tree --write-tree origin/main HEAD` exited 0 and produced tree `7e115448bf32ba3d96d7cad869164cf524b40fc8`. Merge base: `b608d3b5c2b6e17da939a5092a612ca7f93e556a`. |
+| 1 | Review PASS present | PASS | `bd show ga-u49l9u` contains `REVIEW VERDICT: PASS`; source bead is closed with reason `pass`. |
+| 2 | Acceptance criteria met | PASS | Commit changes `sessionTranscriptGetResponse.Messages` to pointer semantics with raw-message helpers, updates call sites, and adds tests for raw branch `messages: []` behavior. Direct checks passed: `go test ./internal/api -run 'TestSessionTranscriptRuntimeContainerDoesNotCustomizeJSON|TestOpenAPISpecInSync' -count=1`; `go test -tags integration -run TestGCLiveContract_BeadsAndEvents -count=1 -timeout 10m ./test/integration`. |
+| 3 | Tests pass | PASS | `HOME=/home/jaword make test-fast-parallel` passed all 8 fast jobs. `HOME=/home/jaword go vet ./...` exited 0. `HOME=/home/jaword make dashboard-check` passed dashboard build, TypeScript checks, e2e typecheck, and dashboard API/BFF package tests. Targeted API schema/runtime tests passed in 0.101s. The live contract regression passed in 41.641s. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes list style, security, spec compliance, coverage, and CI-fix integrity as PASS/N/A with no high-severity findings. No unresolved HIGH finding is recorded in `ga-u49l9u` or `ga-96rgod` notes. |
+| 5 | Final branch is clean | PASS | Before refreshing this gate artifact, `git status --short --branch` in `/var/tmp/gc-deployer-ga-96rgod-gate-1784668932-895011` printed only `## deploy/ga-96rgod-gate`; the gate commit is amended after this edit and status is rechecked before push. |
+| 7 | Single feature theme | PASS | One commit touches only `internal/api` transcript response serialization and adjacent tests: `huma_handlers_sessions_command.go`, `huma_handlers_sessions_query.go`, `session_structured_schema_test.go`, and `structured_leakage_test.go`. |

+- Deploy bead: `ga-9ajrc0`
+- Source bead: `ga-vfurlv`
+- Review bead: `ga-bla86o`
+- Branch: `builder/ga-vfurlv-docgen-tracked-dir-scan`
+- Candidate commit: `eaf0174f97097159ea8c54babbcacadf6728b2f8`
+- Base: `origin/main` at `e9f266c8d1f652a88c15a5dc185c04e58bb2a5dd`
+- Release criteria source: deployer gate prompt. `docs/PROJECT_MANIFEST.md` is not present at this commit.
+- Rebase note (bead `ga-zv2oi4`): this supersedes the prior evaluation recorded at this same path against base `d5cb9125fc9a20a4a720037aec387d76cca2cc60`. The branch was rebased onto current `origin/main` to resolve PR #4377's needs-rebase state. The former `fix(resourcecensus): rebase ledger bump onto origin/main post-#4211` commit (`dcaa53067d71440dd677409996ce7cec81e1e084`) became an empty commit under the new base — its `cmd/gc`+`untagged`/`environment` ledger values now match `origin/main` exactly — and was dropped by the rebase sequencer. The three census-ledger mirror files (`internal/testpolicy/resourcecensus/census.go`, `test/test-resources.toml`, `TESTING.md`) had conflicting `environment`-resource rows during the rebase, resolved by keeping `origin/main`'s newer baseline/reported values, since this branch's own changes make no `cmd/gc` environment calls; the branch's own `subprocess`-resource bumps carried forward unchanged.
+- Rebase note (bead `ga-ugoi7u`): this supersedes the prior evaluation recorded at this same path against base `5f9f6cee2aafaf68113381f398c80360b82a4594`. The automated `hourly pr-audit` order re-flagged PR #4377 as needing rebase after `origin/main` advanced 37 more commits (to `e9f266c8d`), reintroducing conflicts. The branch was rebased again onto current `origin/main`. The former `test(resourcecensus): bump subprocess ledger for gitTrackedTopLevelDirs` commit (`df66905926b5168866e668ddd51282054a4a9376`) became an empty commit under the new base — its three `subprocess`-resource rows conflicted with `origin/main`'s own newer baseline bumps for the same rows, and resolving to `origin/main`'s (higher) values made the commit's entire diff empty against the new base — and it was dropped by the rebase sequencer, the same mechanic as the `dcaa53067`/`environment` drop from the first rebase cycle above. A new commit, `eaf0174f9`, re-derives the correct post-rebase `subprocess` baseline by running `TestRepositoryLedgerMatchesCensusAndDocumentation`'s live census scan (not hand-transcribed) and applying the exact reported drift on top of `origin/main`'s baseline: `all/subprocess` calls 532→533, files 157→158; `untagged/subprocess` source-debt row calls 404→405, files 110→111; `untagged/subprocess` small-debt row calls 402→403, files 109→110.
+
+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | `origin/main` is an ancestor of the candidate (`git merge-base --is-ancestor origin/main eaf0174f9` rc 0). `git rev-list --left-right --count origin/main...eaf0174f9` reported `0 4`. |
+| 1 | Review PASS present | PASS | `ga-bla86o` is closed with close reason `pass`; notes contain `Reviewer verdict: PASS` and no blocking findings. Deploy bead `ga-9ajrc0` records reviewer PASS evidence. Rebasing carries no logic changes on either cycle, so no fresh review pass was required. |
+| 2 | Acceptance criteria met | PASS | Unchanged from the first evaluation: `internal/docgen/schema.go` scopes visible top-level directories through `gitTrackedTopLevelDirs` using `git ls-tree -d --name-only HEAD`, with fallback to the previous walk-all behavior outside a usable git repo. `internal/docgen/schema_test.go`'s `TestAddGoCommentsFilteredSkipsUntrackedTopLevelDirs` carried through both rebases unchanged. Resource census ledger mirrors were re-derived for the new base as described in the rebase note above. |
+| 3 | Tests pass | PASS | `gofmt -l internal/docgen/schema.go internal/docgen/schema_test.go internal/testpolicy/resourcecensus/census.go` produced no output. `go build ./...` passed. `go vet ./...` passed. `go test ./internal/docgen/... ./internal/testpolicy/resourcecensus/...` passed. `make test-fast-parallel` ran 8 fast jobs: 7 passed; 1 `unit-cmd-gc` shard failure was root-caused as pre-existing and unrelated to this diff — see Test Output Summary below. |
+| 4 | No high-severity review findings open | PASS | Unchanged: reviewer notes for `ga-bla86o` say "No findings requiring changes." No unresolved HIGH findings in the deploy or review bead notes. |
+| 5 | Final branch is clean | PASS | Before writing this gate refresh, `git status --short` in the worktree was empty. This gate file is committed as the branch tip before push. |
+| 7 | Single feature theme | PASS | Unchanged: one release theme (bound docgen's schema comment scan to tracked top-level directories, plus the resource-census ledger mirror updates the fixture requires). This rebase cycle's additions (`eaf0174f9` and this gate refresh) are mechanical rebase upkeep, not new theme scope. |
+
+## Commit Set
+
+| Commit | Summary |
+|--------|---------|
+| `288c2da81` | `fix(docgen): bound schema doc-gen walk to git-tracked top-level dirs` |
+| `2b12a90b3` | `chore: release gate PASS for ga-9ajrc0-docgen-tracked-dir-scan` |
+| `93a9c2a8d` | `chore(release-gate): refresh ga-9ajrc0 evidence after rebase onto main` |
+| `eaf0174f9` | `test(resourcecensus): re-derive subprocess ledger bump on second rebase` |
+
+The former `fb8a69489`/`df6690592` pair (first-rebase-cycle hashes for the docgen fix and its ledger bump) were superseded by this second rebase: `fb8a69489`'s content replayed cleanly as `288c2da81` (same 2-file, 124-line diff; new hash from the new parent), while `df6690592` became empty and was dropped — see rebase note above. `dcaa53067`, dropped in the first rebase cycle, remains dropped.
+
+## Test Output Summary
+
+- `go build ./...`: PASS
+- `go test ./internal/docgen/... ./internal/testpolicy/resourcecensus/...`: PASS
+- `go vet ./...`: PASS
+- `make test-fast-parallel`: 7/8 fast jobs passed (`fsys-darwin-compile`, `unit-core`, `unit-cmd-gc-1-of-6`, `unit-cmd-gc-2-of-6`, `unit-cmd-gc-3-of-6`, `unit-cmd-gc-5-of-6`, `unit-cmd-gc-6-of-6`). 1 job failed, root-caused as pre-existing and independent of this diff:
+  - `unit-cmd-gc-4-of-6`: `TestProductMetricsServiceChildEnvSupervisorStart` fails with `HOME override "/home/jaword/james-claude" differs from the user home "/home/jaword"; platform supervisor requires the real HOME` — the identical sandbox `HOME`-override guard rail documented in the first rebase cycle above. `cmd/gc/productmetrics_service_child_env_test.go` is byte-identical to `origin/main` (`git diff origin/main -- cmd/gc/productmetrics_service_child_env_test.go` is empty), and this branch's full diffstat vs `origin/main` touches only `internal/docgen`, `internal/testpolicy/resourcecensus`, `test/test-resources.toml`, `TESTING.md`, and this gate file — nothing on the supervisor path. Not a regression.
+  - The second flake documented in the first rebase cycle, `TestProductMetricsLifecycleCommandPathMatrixAttemptsOnce/jsonl_failure`, ran this cycle (inside `unit-cmd-gc-2-of-6`) and passed, consistent with its documented sensitivity to ambient city state rather than a deterministic failure.

+# Release Gate: hold-label-routed-to doctor check

+Bead: ga-ac03mi
+Branch: builder/ga-fm2vgd.1-hold-label-routing-doctor-check
+Head: 0e8641d5908d6746269df5906ecd7b1afe1d9967
+Base: origin/main b7d312eb5ae026d87ed655908de9d090e7a4f07a
+Date: 2026-07-18
+
+Note: docs/PROJECT_MANIFEST.md is not present on origin/main or this branch.
+This gate uses the deployer release criteria supplied by the Gas City role
+prompt and TESTING.md for test selection.
+
+## Summary
+
+PASS. The branch is current with origin/main, has a closed reviewer PASS, is
+limited to the cmd/gc doctor-check subsystem, and passed the focused acceptance
+tests plus the repo fast baseline.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | `git rev-list --left-right --count origin/main...origin/builder/ga-fm2vgd.1-hold-label-routing-doctor-check` returned `0 5`; merge-base equals origin/main (`b7d312eb5ae026d87ed655908de9d090e7a4f07a`). |
+| 1 | Review PASS present | PASS | Review bead ga-fm2vgd.3 is closed with close reason `PASS: hold-label-routed-to now scans all non-closed beads...`. |
+| 2 | Acceptance criteria met | PASS | `cmd/gc/doctor_hold_label_routed_to.go` registers `hold-label-routed-to`, scans city and rig stores, leaves `Status` unset with `AllowScan: true`, excludes `hold:external`, and fixes drift through `SetMetadata`. `cmd/gc/doctor_hold_label_routed_to_test.go` covers missing and mismatched `gc.routed_to`, city and rig stores, `hold:external`, arbitrary hold values, idempotent fix behavior, and the `in_progress` regression case. No production branch special-cases a role name; role-like strings appear only as generic test fixture values. |
+| 3 | Tests pass | PASS | `go test ./cmd/gc/ -run 'TestHoldLabelRoutedTo|TestBuildDoctorChecks_NameSetUnchanged' -v` passed 5/5. `go build ./...` passed. `go vet ./...` passed. `make test-fast-parallel` passed all 8 fast jobs (`fsys-darwin-compile`, `unit-core`, and `unit-cmd-gc-1-of-6` through `unit-cmd-gc-6-of-6`). |
+| 4 | No high-severity review findings open | PASS | ga-fm2vgd.3 contains no unresolved HIGH finding and was closed PASS after the earlier request-changes bead ga-fm2vgd.2 was fixed. |
+| 5 | Final branch is clean | PASS | Scratch worktree was clean before writing this gate file; final cleanliness is verified after committing this checklist. |
+| 7 | Single feature theme | PASS | Commit set touches one subsystem: `cmd/gc` doctor check registration, implementation, tests, and doctor-check golden names. |

+## Criteria
+
+| # | Criterion | Verdict | Evidence |
+|---|-----------|---------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. Initial branch was 2 behind / 3 ahead. Approved bounded self-rebase succeeded and pushed with `--force-with-lease`: `6b64f282e19a035fce5cd98de9e8a56aadc84ea6 -> 190d517312a0a07812cb74cadd44d960bfad7260`. After refetch: `git rev-list --left-right --count origin/main...origin/builder/ga-ntbpyb.1-tmux-socket-consolidation` returned `0 3`; `git merge-tree --write-tree origin/main origin/builder/ga-ntbpyb.1-tmux-socket-consolidation` exited 0. |
+| 1 | Review PASS present | PASS | Review bead `ga-1mlbj4` is closed with close reason `pass`; notes contain `Review verdict: PASS` and independent verification evidence. |
+| 2 | Acceptance criteria met | PASS | Source bead `ga-ntbpyb.1` is closed with all 4 acceptance criteria satisfied. Rebased branch contains shared `test/tmuxtest.NewSocketParentDir`, gct parent-dir sweep coverage including real SIGKILL/flock test, migrated tmux/integration/cmd call sites, and SIGKILL-safe Dolt shell scratch-dir cleanup. Bundled `ga-xlwr5u` is closed and only consolidates duplicate test `shortTempDir` helpers through `internal/testutil.ShortTempDir`. |
+| 3 | Tests pass | PASS | `gofmt` on touched Go files clean; `go build ./...` pass; `go vet ./...` pass; focused packages pass: `go test ./test/tmuxtest/... ./internal/runtime/acp/... ./internal/runtime/subprocess/... ./internal/runtime/tmux/... ./internal/testpolicy/resourcecensus/...`; focused `cmd/gc` subset pass; `go test -c -tags integration ./test/integration` pass; `make test-fast-parallel` pass with all 8 fast shards green. `shellcheck -s sh` reports only pre-existing warnings outside this branch's added hunks in the touched Dolt scripts. |
+| 4 | No high-severity review findings open | PASS | Review notes record no findings; unresolved HIGH findings count is 0. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` in `/var/tmp/gascity-b551k9-rebase.DsonXl` shows a clean branch before the gate file commit. |
+| 7 | Single feature theme | PASS | Commit set is one test-infrastructure theme: tmux socket temp-dir/orphan cleanup, adjacent test temp-dir helper consolidation, and required resource-census ledger updates. There is no production behavior or unrelated user-facing feature bundled into the branch. |

+# Release Gate: ambient-city Dolt port detection arm
+
+- Deploy bead: `ga-ceutvg`
+- Source bead: `ga-cnyuq1`
+- Review bead: `ga-pzuio2` (closed, PASS)
+- Reviewed source SHA: `145ef9124ac4111fd4a5935e47a6af85087e0f70`
+- Final candidate SHA: `e3dba4580fff695194f4249611896b13685e4ff1`
+- Base: `origin/main@bf665eae52d14bf9f67112c2c3f6915389f3c913`
+- Source branch (provenance only): `builder/ga-ceutvg-ambient-city-dolt-port-arm-fix`
+- Isolated deploy branch: `deploy/ga-ceutvg-gate`
+
+The repository does not contain `docs/PROJECT_MANIFEST.md` at this revision.
+This checklist therefore applies the canonical seven deployer release criteria
+and the repository quality gates in `AGENTS.md` and `TESTING.md`.
+
+## Freshness evaluation (criterion 6 first)
+
+PASS. The canonical `scripts/rebase-resolve-lib.sh`
+`attempt_bounded_self_rebase` helper replayed the reviewed patch twice as
+`origin/main` advanced during evaluation:
+
+- `145ef9124ac4111fd4a5935e47a6af85087e0f70` ->
+  `41b37a639bce8f1ab1a1a96f7cdb200917d44a8f`
+- `41b37a639bce8f1ab1a1a96f7cdb200917d44a8f` ->
+  `e3dba4580fff695194f4249611896b13685e4ff1`
+
+Both helper calls returned `0` and completed their explicit
+`--force-with-lease` pushes. `git range-diff` reports all three feature
+commits patch-identical between the reviewed range and the final range.
+After the criterion-3 suite, `git ls-remote` still reported
+`origin/main@bf665eae52d14bf9f67112c2c3f6915389f3c913`, and
+`git merge-base --is-ancestor origin/main e3dba4580` returned success.
+
+## Gate criteria
+
+| # | Criterion | Result | Evidence |
+|---|---|---|---|
+| 1 | Review PASS present | **PASS** | `ga-pzuio2` is closed with `[VERDICT: PASS]`. The deploy bead also contains a fresh exact-SHA reviewer PASS for `145ef9124`; the final candidate is a patch-identical bounded rebase as shown by `git range-diff`. |
+| 2 | Acceptance criteria met | **PASS** | `internal/testenv` adds an independent, additive ambient-city arm without removing the existing `3307` environment arm; walks upward for `city.toml`; reads `.gc/runtime/packs/dolt/dolt-state.json` via a fixed-shape `json:"port"` field; rejects only positive discovered ports; documents the separately-executed production-`gc` limitation; and exercises neutral synthetic ports `19999`/`20000`, neither `3307` nor fleet port `28231`. The legacy-port regression suite remains green. |
+| 3 | Tests pass | **PASS** | `gofmt -l` clean on all three changed files; `go build ./...` PASS; `go vet ./...` PASS; focused `TestAmbientCityDoltPort`, `TestInitRefusesProdDoltPort`, and `TestInitRefusesAmbientCityDoltPort` PASS (6 + 27 + 3 subtests); full `go test -count=1 ./internal/testenv/...` PASS; `TestRepositoryLedgerMatchesCensusAndDocumentation` PASS; explicit `make test-fast-parallel` PASS, all 9 jobs. The final bounded-helper push also passed the configured pre-push hook on the same SHA. |
+| 4 | No high-severity review findings open | **PASS** | Review verdict is PASS with zero unresolved HIGH findings. Its OWASP walk found no injection, XSS, SQL, auth, or untrusted-network surface; the guard only adds refusal conditions. |
+| 5 | Final branch is clean | **PASS** | Before writing this checklist, `git status --porcelain=v1` was empty and `git diff --check origin/main..HEAD` passed. The checklist is the only deployer-authored file and will be committed on the isolated gate branch. |
+| 6 | Branch diverges cleanly from main | **PASS** | Evaluated first. Final candidate contains `origin/main@bf665eae5`; remote main and source ref were re-read after tests and remained stable. |
+| 7 | Single feature theme | **PASS** | The feature range changes only `internal/testenv/testenv.go`, `internal/testenv/testenv_internal_test.go`, and `internal/testenv/testenv_test.go`, all implementing and proving one ambient-city Dolt-port refusal arm. |
+
+## Acceptance mapping
+
+- Self-relative detection: `ambientCityDoltPort` walks from the test process
+  working directory to a `city.toml` root and reads that city's managed-Dolt
+  state.
+- Additive behavior: `refuseProdDoltPort` still calls the existing
+  `ProdDoltPort` arm before consulting the ambient-city arm.
+- Neutral end-to-end proof: matching `19999` panics, non-matching `20000`
+  survives, and the explicit opt-out permits `19999`.
+- Existing behavior preserved: all 27 `TestInitRefusesProdDoltPort` cases pass.
+- Resource budget preserved: the shared subprocess assertion helper keeps the
+  checked resource-census ledger unchanged.
+- Scope boundary documented: a separately executed production `gc` binary
+  does not import `internal/testenv`; that follow-up remains outside this
+  change.
+
+## Gate verdict
+
+**PASS** — eligible for an isolated deploy branch and pull request.

+- Implementation bead: ga-p0u752
+
+Note: `docs/PROJECT_MANIFEST.md` is absent in this Gas City checkout. This gate uses the deployer prompt's seven release criteria and the repository's `TESTING.md` guidance.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | `ga-sd5w70` is closed with `REVIEWER VERDICT: PASS` and no blocking findings. |
+| 2 | Acceptance criteria met | PASS | Diff contains the structural named-session skip in `cmd/gc/pool_desired_state.go`, removes the old expanded-identity guard in `cmd/gc/build_desired_state.go`, and adds/reuses the required tests. |
+| 3 | Tests pass | PASS | `go build ./cmd/gc/...`, `go vet ./...`, focused `cmd/gc` tests, and `make test-fast-parallel` passed on the final branch. First fast run failed in unrelated supervisor-city tests under a longer TMPDIR; the exact failures passed on both branch and `origin/main` with short TMPDIR, then the full fast baseline passed with short TMPDIR. |
+| 4 | No high-severity review findings open | PASS | Review notes contain no unresolved HIGH findings. Prior Medium/Low findings from the design chain are resolved or documented as non-blocking. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` was clean before this gate file was added; this file is the only gate commit payload. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-tree --write-tree HEAD origin/main` exited 0 and produced tree `acdc91b0de0eed899a1ed8d33e13bfe6aca23d22`. The new main commit since the branch base touches only `.github/workflows/ci.yml`, `Makefile`, and `scripts/check-core-boundary.sh`. |
+| 7 | Single feature theme | PASS | Commit set is one `cmd/gc` reconciler/session-demand fix: `cmd/gc/build_desired_state.go`, `cmd/gc/build_desired_state_ga80pen8_test.go`, `cmd/gc/pool_desired_state.go`, `cmd/gc/pool_desired_state_test.go`. |
+
+## Acceptance Evidence
+
+Implementation bead `ga-p0u752` required:
+
+- Add a suspension-aware configured-named-session identity check before `wake-known-identity` pool demand: PASS.
+- Delete the named-work-ready `SupportsExpandedSessionIdentities` suppression guard: PASS.
+- Keep `TestBuildDesiredState_MultiSlotPoolNamedSession_OneRoutedBeadProvisionsTwoWorkers` green with the guard deleted: PASS.
+- Add a reaped named-session bare-identity recovery test proving named-tier recovery without a competing pool worker: PASS.
+- Cover the suspended-agent helper behavior: PASS via `TestIsConfiguredNamedSessionIdentity`.
+- Keep `TestSharedTemplateAssignee_Tier1CrashRecoveryCrossAdopts` green: PASS.
+
+## Test Log
+
+- `gofmt -l cmd/gc/build_desired_state.go cmd/gc/build_desired_state_ga80pen8_test.go cmd/gc/pool_desired_state.go cmd/gc/pool_desired_state_test.go`: PASS, no output.
+- `git diff --check origin/main...HEAD`: PASS.
+- `git config core.hooksPath`: `.githooks`.
+- `TMPDIR=/var/tmp/gascity-test-ga-cjhqf0 go build ./cmd/gc/...`: PASS.

+- `TMPDIR=/var/tmp/gascity-test-ga-cjhqf0 go test ./cmd/gc/ -run 'ControlReady|WorkflowServeControlReadyQuery|RunWorkflowServe|ComputePoolDesiredStates_WakeKnownIdentitySkipsConfiguredNamedSession|IsConfiguredNamedSessionIdentity|BuildDesiredState_NamedSessionBareIdentityReaped_RecoversViaNamedTier|BuildDesiredState_MultiSlotPoolNamedSession_OneRoutedBeadProvisionsTwoWorkers|SharedTemplateAssignee_Tier1CrashRecoveryCrossAdopts' -count=1 -v`: PASS.
+- `TMPDIR=/var/tmp/gascity-test-ga-cjhqf0 make test-fast-parallel`: initial FAIL in supervisor-city tests unrelated to the diff.
+- Exact initial failures rerun on branch with short TMPDIR: PASS.
+- Exact initial failures rerun on `origin/main` with short TMPDIR: PASS.
+- `TMPDIR=$(mktemp -d /var/tmp/gf.XXXXXX) make test-fast-parallel`: PASS, all 8 fast jobs passed.

+- Release criteria source: deployer gate instructions; `docs/PROJECT_MANIFEST.md` is not present in this checkout.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Review bead `ga-wx2gub` is closed with close reason `pass` and an explicit `REVIEW VERDICT: PASS` for the reviewed commit. |
+| 2 | Acceptance criteria met | PASS | Each of the three affected tests sets `GC_CITY_PATH` to its temporary city immediately after changing directory. This selects the explicit-environment resolution path before ambient upward discovery, preserving the tests when the later test-binary ambient-discovery guard lands. |
+| 3 | Tests pass | PASS | `make test-fast-parallel` passed all nine jobs. `go build ./...`, `go vet ./...`, and the focused run of all three changed tests passed. |
+| 4 | No high-severity review findings open | PASS | The review found no blockers, no production or security surface, and no coverage gap. Unresolved HIGH findings: 0. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` reported a clean detached checkout before this gate file was added. `gofmt` and `git diff --check` were clean. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-base --is-ancestor origin/main 1c339dea92911f37e8aaefed82176c69a03bd96d` passed, and `git merge-tree --write-tree` completed cleanly. No self-rebase was required. |
+| 7 | Single feature theme | PASS | The one-file, three-line test-only commit has one theme: removing `cmd_config_test.go` tests from ambient city discovery. |
+
+## Verification Commands
+
+| Command | Result |
+|---------|--------|
+| `make test-fast-parallel` | PASS: all 9 fast jobs passed |

+
+## Gate Criteria
+
+Criterion 6 was evaluated first per deployer instructions.
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Review bead `ga-edh5gn` is closed with `Reviewer verdict: PASS`. The reviewer independently verified the root cause, deterministic replacement failure path, formatting, static checks, and coverage intent. |
+| 2 | Acceptance criteria met | PASS | The branch changes only `cmd/gc/metrics_lifecycle_test.go`, replacing the ambient `gc events --json` failure case with mutually exclusive `gc events --after 1 --after-cursor x` flags. Code inspection confirmed `cmd/gc/cmd_events.go` checks that mutual exclusion at the start of `RunE`, before seq/follow/watch/plain branches can touch city or supervisor state. `GC_CITY=/home/jaword/projects/gc-management go test ./cmd/gc -run '^TestProductMetricsLifecycleCommandPathMatrixAttemptsOnce$' -count=5` passed. `gofmt -l cmd/gc/metrics_lifecycle_test.go` produced no output. `git grep -n -E 'jsonl failure|jsonl_failure' -- '*.go'` produced no output. |
+| 3 | Tests pass | PASS | `TMPDIR=/var/tmp/gd4 make test-fast-parallel` passed all fast jobs. `TMPDIR=/var/tmp/gd4 go vet ./...` passed. A prior fast run with a long deployer TMPDIR failed from Unix socket path length (`bind/connect: invalid argument`); rerunning with the short `/var/tmp/gd4` path passed. |
+| 4 | No high-severity review findings open | PASS | Review bead notes contain a PASS verdict and no open HIGH findings. The deployer inspection found no additional high-severity issue in this test-only change. |
+| 5 | Final branch is clean | PASS | Before adding this gate file, `git status --short --branch` in `/var/tmp/gascity-builder-ga-m1uo4w` showed a clean `builder/ga-m1uo4w-fix-events-json-deprecation-test` branch tracking `origin/builder/ga-m1uo4w-fix-events-json-deprecation-test`. The only pending change before commit is this release-gate file. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-tree --write-tree origin/main origin/builder/ga-m1uo4w-fix-events-json-deprecation-test` returned `rc=0` and tree `1841cb3761b30e20ad599a7e7640bb03798a60f5`. |
+| 7 | Single feature theme | PASS | The effective diff from `origin/main` is a one-line test-case replacement in `cmd/gc/metrics_lifecycle_test.go`, scoped to the product-metrics lifecycle matrix for the `gc events` command path. |

+## Gate Results
+
+Criterion 6 was evaluated first as required.
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Source review bead `ga-do76zk` is closed with `REVIEW VERDICT: PASS`. Its independent review covered the complete 17-line diff, build, vet, focused tests, security, coverage, and CI-integrity concerns. |
+| 2 | Acceptance criteria met | PASS | The patch adds `t.Setenv("GC_CITY_PATH", dir)` immediately after the existing `t.Chdir(dir)` at 17 sites in the four specified `cmd/gc` test files. The focused smoke passed all 17 affected tests. No production code changed. |
+| 3 | Tests pass | PASS | On gated commit `7868a0148`, `go build ./...` and `go vet ./...` passed; the 17 affected tests passed; and `make test-fast-parallel` passed all nine jobs (`unit-core`, six `unit-cmd-gc` shards, `fsys-darwin-compile`, and `push-gate-lock-selftest`). |
+| 4 | No high-severity review findings open | PASS | The source review records no security, coverage, CI-integrity, or other unresolved HIGH finding. Deployer inspection found no additional high-severity concern in this test-only change. |
+| 5 | Final branch is clean | PASS | Before this checklist was added, `git status --porcelain=v1` produced no output and `git diff --check origin/main...HEAD` passed. This checklist is committed as the isolated deploy branch tip. |
+| 6 | Branch diverges cleanly from main | PASS | The reviewed commit did not contain current main, so the canonical bounded helper replayed it from `0230167ae9` to `7868a01485` on `origin/main@9efcfb5411`. `git range-diff` reported the patch as identical, the lease-protected push to the isolated deploy branch succeeded, and `git ls-remote` verified the remote at `7868a0148515db3e59e635dd0e2ec5e909876386`. |
+| 7 | Single feature theme | PASS | The commit changes four `cmd/gc` test files only, with one repeated purpose: make city selection explicit instead of relying on ambient upward discovery. |
+
+## Acceptance Checks

+- PASS: The event-emit fallback test pins its temporary city explicitly.
+- PASS: Six formula-show tutorial tests pin their temporary city explicitly.
+- PASS: Eight formula version-check tests pin their temporary city explicitly.
+- PASS: Two order show/history tests pin their temporary city explicitly.
+- PASS: The change remains test-only: 17 insertions in four files.
+- PASS: Parent bead `ga-klo4gz` remains sequenced after the full migration; this
+  batch does not clear the ambient-discovery guard to land.

+# Release Gate: pre-push bead-ownership/staleness guard
+
+Bead: ga-evd1s7
+Source bead: ga-fip9ps.1
+Review bead: ga-37f7xi
+
+Deploy source: 71de27f256ed6838b9c2446c5255be25f21b2fb9
+Source branch provenance only: builder/ga-evd1s7-gate-rebase
+Deploy branch: deploy/ga-evd1s7-gate
+Base checked: origin/main at 2abd12e857a2c38875db51b681736a4e053b89b1
+
+Note: the original reviewed deploy source 7ced0d3ab710e3b4c39a9d1468923b59ea09d840 failed an earlier criterion-6 freshness gate. Builder rebased the resource-census ledger reconciliation, reviewer refresh-reviewed the rebased result, and bead metadata now points to 71de27f256ed6838b9c2446c5255be25f21b2fb9 as the deploy target.

+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. `git merge-tree --write-tree origin/main 71de27f256ed6838b9c2446c5255be25f21b2fb9` exited 0 and produced tree `d565adbeeb42f6aed1494388e05bc280f086f413`. |
+| 1 | Review PASS present | PASS | `bd show ga-37f7xi` records `REVIEW VERDICT: PASS`; `bd show ga-evd1s7` records `REFRESH REVIEW VERDICT: PASS` for 71de27f256ed6838b9c2446c5255be25f21b2fb9. |
+| 2 | Acceptance criteria met | PASS | The diff implements the requested guard surfaces: `scripts/push-ownership-guard.sh`, `.githooks/pre-push`, Layer B call in `scripts/rebase-resolve-lib.sh`, Go passthrough test, real bare-remote shell harness, and resource-census ledger sync. Direct acceptance checks passed: guard harness 19/19, rebase-resolve harness 22/22, resource-census ledger test PASS. |
+| 3 | Tests pass | PASS | `go build ./...`, `go vet ./...`, `go test ./scripts`, `go test ./internal/testpolicy/resourcecensus`, `go test ./internal/testpolicy/resourcecensus -run TestRepositoryLedgerMatchesCensusAndDocumentation`, `scripts/test-push-ownership-guard.sh`, `scripts/test-rebase-resolve.sh`, `shellcheck .githooks/pre-push scripts/push-ownership-guard.sh scripts/test-push-ownership-guard.sh scripts/test-rebase-resolve.sh scripts/rebase-resolve-lib.sh`, and `make test-fast-parallel` all exited 0. Fast suite summary: 8/8 jobs passed. |
+| 4 | No high-severity review findings open | PASS | Review bead and refresh notes both state no blocking findings. No unresolved HIGH findings are recorded in the reviewed bead notes. |
+| 5 | Final branch is clean | PASS | Before refreshing this gate file, `git status --short --branch` on `deploy/ga-evd1s7-gate` printed only `## deploy/ga-evd1s7-gate`. The gate file is committed on top of the deploy source as the only deployer-added change. |
+| 7 | Single feature theme | PASS | The commit set touches one subsystem: pre-push ownership/staleness guarding and its direct test/resource-census wiring. Diff scope is 9 files, 791 insertions, 16 deletions. |

+# Release Gate: ga-ey4tcs Store.Tx session lifecycle writes
+
+Gate evaluated: 2026-07-14T04:05:22Z
+
+Bead: `ga-ey4tcs` - needs-deploy: Wrap closeBead/rollbackPendingCreate/reopen in Store.Tx
+
+Source review bead: `ga-23a84u` - Review verdict: PASS
+
+Branch: `builder/ga-ey4tcs-store-tx-rebuild-v3`
+
+Base: `origin/main` at `5e2fa2872a6dc0de996397f6face30893a4c14da`
+
+Head before gate commit: `afdf84fbe0e65c1542816bc55dee23c6b451d220`
+
+Manifest note: `docs/PROJECT_MANIFEST.md` is not present in this repository at this head, so the gate uses the deployer prompt criteria and the local `TESTING.md` guidance.
+
+## Criteria
+
+| # | Criterion | Verdict | Evidence |
+|---|-----------|---------|----------|
+| 1 | Review PASS present | PASS | `bd show ga-23a84u` contains `REVIEW VERDICT: PASS`, closes with reason `pass`, and states "No blocking findings." |
+| 2 | Acceptance criteria met | PASS | The single commit wraps the requested session lifecycle write groups in `Store.Tx`: `closeBead`, `closeFailedCreateBead`, `rollbackPendingCreate`, and `reopenClosedConfiguredNamedSessionBead`. The diff keeps cascade cleanup outside the transaction, adds the explicit already-closed rollback guard, and pins the behavior with transaction/failure/idempotence tests. |
+| 3 | Tests pass | PASS | `gofmt -l` on the 4 touched files produced no output. `go build ./...` passed. `go vet ./...` passed. Targeted `go test -count=1 ./cmd/gc -run ...` passed. `make test-fast-parallel` passed all 8 fast jobs. |
+| 4 | No high-severity review findings open | PASS | Review bead `ga-23a84u` reports no blocking findings and no high-severity open findings in notes. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` showed `## builder/ga-ey4tcs-store-tx-rebuild-v3...origin/builder/ga-ey4tcs-store-tx-rebuild-v3` with no dirty paths before writing this gate file. |
+| 6 | Branch diverges cleanly from main | PASS | After `git fetch origin main`, `git merge-base --is-ancestor origin/main HEAD` exited 0, `git rev-list --left-right --count origin/main...HEAD` returned `0 1`, and `git merge-tree` reported clean. |
+| 7 | Single feature theme | PASS | The branch is one commit ahead of main and touches only `cmd/gc/session_beads.go`, `cmd/gc/session_beads_test.go`, `cmd/gc/session_lifecycle_parallel.go`, and `cmd/gc/session_lifecycle_parallel_test.go` for one session lifecycle atomic-write theme. |

+## Scope
+
+This PR ports the deployer's bounded self-rebase helper into the Gas City repo so deployer gate criterion 6 can self-heal provably trivial branch staleness. The change adds:
+
+- `scripts/rebase-resolve-lib.sh`
+- `scripts/test-rebase-resolve.sh`
+- `scripts/rebase_resolve_lib_test.go`
+- resource-census ledger updates in `internal/testpolicy/resourcecensus/census.go`, `test/test-resources.toml`, and `TESTING.md`
+
+## Criterion 6: Branch Diverges Cleanly From Main
+
+PASS.
+
+Evidence:
+
+- Original reviewed source branch was stale against current `origin/main` (`origin/main...origin/builder/ga-yvrg05.1-rebase-resolve-lib-port` was `2 2`) but conflict-free by `git merge-tree --write-tree origin/main origin/builder/ga-yvrg05.1-rebase-resolve-lib-port`.
+- The original builder worktree was not used because it had unrelated untracked scaffold residue. A clean deployer-owned branch was cut from the reviewed source branch.
+- `scripts/rebase-resolve-lib.sh` was sourced from the candidate branch and `attempt_bounded_self_rebase deploy/ga-gf0sxw-rebase-resolve-lib-port-20260715083438 main` returned `0`.
+- Self-rebase audit: `BEFORE_SHA=d9c61bbb68458c1908961198fba0ae13500bb2dd`, `AFTER_SHA=150afca8a983b1f81aed026d1960e95caae96da2`.
+- The helper pushed with `--force-with-lease`; the push returned 0.
+- `git rev-list --left-right --count HEAD...origin/main` after rebase: `2 0`.
+- `git merge-tree --write-tree origin/main HEAD` after rebase returned tree `4ba0e24723d58c10e96221fbd7367b4d92d31175` with exit 0.
+
+## Release Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | `ga-ohb1ru` is closed with close reason `pass` and notes contain `Reviewer verdict: PASS`. |
+| 2 | Acceptance criteria met | PASS | Library port is byte-identical to `/home/jaword/projects/gc-management/packs/actual/deployer/scripts/rebase-resolve-lib.sh` (`cmp -s` exit 0). Shell test diff against the source pack is exactly the expected two-line path-layout adjustment from `PACK_DIR` + `LIB` to sibling `LIB="$TEST_DIR/rebase-resolve-lib.sh"`. The caller rationale was independently reviewed in `ga-ohb1ru`: deployer formula sources `scripts/rebase-resolve-lib.sh` from each target rig checkout. |
+| 3 | Tests pass | PASS | `attempt_bounded_self_rebase` push triggered `.githooks/pre-push`; for this new Go-changing branch the hook runs `make test-fast-parallel`, and the push returned 0. Additional explicit checks: `bash scripts/test-rebase-resolve.sh` passed `pass=22 fail=0` with a valid `TMPDIR`; `go test ./scripts/... -run RebaseResolve -v` passed; `go test ./internal/testpolicy/resourcecensus/...` passed; `shellcheck scripts/rebase-resolve-lib.sh scripts/test-rebase-resolve.sh` passed; `gofmt -l scripts/rebase_resolve_lib_test.go` returned empty; `go vet ./...` passed; `go build ./...` passed. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes list exactly two LOW severity, non-blocking comment-only findings about stale path comments. No HIGH or CRITICAL findings are present in `ga-ohb1ru`. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` before writing this gate file showed no working-tree changes. After this gate file is committed, deployer will re-check a clean tree before push/PR. |
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first; see dedicated section above. |
+| 7 | Single feature theme | PASS | Commit set touches one feature theme: deployer bounded self-rebase helper and its direct tests/resource-census bookkeeping. No independent user-facing feature is bundled. |

+# Release Gate: push-ownership guard multi-level bead IDs
+
+- Deploy bead: `ga-hzy30q`
+- Source bead: `ga-nnjcuc.2`
+- Reviewed commit: `7af0671436ba10f2e0f275e3ef627393806651ef`
+- Deploy branch: `deploy/ga-hzy30q-gate`
+- Evaluated: 2026-07-24
+- Gate source: deployer prompt release-gate table. `docs/PROJECT_MANIFEST.md` was not present in this checkout.
+
+## Summary
+
+PASS. This is a single-theme shell guard fix. It changes only the push ownership guard and its shell test harness so branch names containing repeatable dotted bead IDs, such as `ga-o3ko1j.4.3`, resolve the full bead ID instead of truncating to `ga-o3ko1j.4`.
+
+## Criteria
+
+| # | Criterion | Verdict | Evidence |
+|---|-----------|---------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Checked first. `git fetch origin main`; `git merge-tree --write-tree origin/main 7af0671436ba10f2e0f275e3ef627393806651ef` returned tree `5179bfeb0cd424b4a6381c18bfad45b8758ec7d7`; `git diff --check origin/main...7af0671436ba10f2e0f275e3ef627393806651ef` produced no output. |
+| 1 | Review PASS present | PASS | Deploy bead `ga-hzy30q` records reviewer PASS for source bead `ga-nnjcuc.2`; source notes contain `REVIEWER VERDICT: PASS`. |
+| 2 | Acceptance criteria met | PASS | Commit set is the expected red/green pair: `d877d93e5` and `7af067143`. Diff is limited to `scripts/push-ownership-guard.sh` and `scripts/test-push-ownership-guard.sh`; no `cmd/gc` or dead-assignee fallback files are included. Targeted guard suite includes the regression `resolve/branch-resolves-full-multi-level-subbead-id`. |
+| 3 | Tests pass | PASS | `bash scripts/test-push-ownership-guard.sh` passed `20/20`; `shellcheck scripts/push-ownership-guard.sh scripts/test-push-ownership-guard.sh` passed with ShellCheck 0.11.0; `go build ./...` passed; `go vet ./...` passed; `make test-fast-parallel` passed all 8 fast jobs. |
+| 4 | No high-severity review findings open | PASS | `bd list --status open --limit 0 | rg -i -- 'ga-hzy30q|ga-nnjcuc\\.2|HIGH|request-changes|security'` returned only sling helper bead `ga-pqt5hs`; no open HIGH/request-changes finding was found. |
+| 5 | Final branch is clean | PASS | Before adding this gate file, `git status --short --branch` returned only `## deploy/ga-hzy30q-gate`. The gate file is committed as the final branch tip before push. |
+| 7 | Single feature theme | PASS | The commit set touches one subsystem: `scripts/push-ownership-guard.sh` plus its test harness. Removing this fix would only affect branch-to-bead ID resolution for push guard checks. |

+
+## Release Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | `ga-7fqxay` notes contain re-review verdict `PASS` for commit `c93d9a7bf` after the first review's medium `DefaultSlingQuery` finding was fixed. Single-pass review is sufficient while gemini second-pass is disabled. |
+| 2 | Acceptance criteria met | PASS | `ga-imtb36.1` produced the clean release branch from current `origin/main`, recorded branch/head/log/changed files, and verified no behavior drift from the reviewed range. This gate independently confirmed the release branch contains only the two routed_to resolver commits listed above. |
+| 3 | Tests pass | PASS | `make test-fast-parallel` passed in a private `/tmp` namespace (`bwrap --tmpfs /tmp`) with short `/var/tmp/gf.*` `TMPDIR`, after initial host-environment attempts exposed the shared `/tmp` tmpfs at 100% and Unix socket path-length artifacts. `go vet ./...` clean. `go build ./...` clean. `gofmt -l` over all 16 changed Go files clean. `git diff --check origin/main..HEAD` clean. |
+| 4 | No high-severity review findings open | PASS | `ga-7fqxay` had one medium finding in the first review; the fix was applied in `c93d9a7bf` and the re-review verdict is PASS. No unresolved HIGH findings are present in the review notes. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` before writing this gate reported only `## HEAD (no branch)` in the detached gate worktree. The only deployer-authored change is this release gate file. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-base --is-ancestor origin/main HEAD` passed, `git merge-tree $(git merge-base HEAD origin/main) HEAD origin/main` produced no conflicts, and `git diff --check origin/main..HEAD` passed. |
+| 7 | Single feature theme | PASS | The diff is one release theme: centralizing `gc.routed_to` derivation via `agentutil.RoutedToIdentity`, making `doctor --fix` reconcile v2 routed_to namespace drift, and the directly related `DefaultSlingQuery` PoolName-collapse regression fix. The unrelated pool-resume readiness commits `3ed3a448b` and `b9f3c4239` are not ancestors of this branch (`git merge-base --is-ancestor` returned non-zero for both). |
+
+## Bead Acceptance
+
+| Acceptance | Result | Evidence |
+|------------|--------|----------|
+| Wait for `ga-imtb36.1` clean branch details | PASS | `ga-imtb36.1` is closed and recorded branch `deploy/ga-imtb36-routed-to-resolver-clean`, head `202a64eb0013cd5457d883060955c581909ced89`, and fork push evidence. |
+| Run standard deploy gate and verify single feature theme | PASS | Release criteria above are all PASS; criterion 7 records the theme and exclusion checks. |
+| Confirm unrelated pool-resume readiness changes are excluded | PASS | Candidate log contains only `57991b77c` and `202a64eb0`; `3ed3a448b` and `b9f3c4239` are absent from the candidate ancestry. |
+| Record build, smoke, vet, and test evidence | PASS | Evidence is recorded in criterion 3. |
+| On PASS, open/update PR and route merge request | PENDING | To be completed after committing and pushing this gate file. |
+| On FAIL, route back to PM | PASS | Not applicable: no failed gate criterion. |
+
+## Push Target
+
+- `git push --dry-run --no-verify origin HEAD:refs/heads/deploy/ga-imtb36-routed-to-resolver-clean` succeeded, so the push target is `origin`.
+- `git push --dry-run --no-verify fork HEAD:refs/heads/deploy/ga-imtb36-routed-to-resolver-clean` reported `Everything up-to-date`; the original clean branch also exists on `fork`.

+
+Candidate head before gate commit: 62cc8687a36e37dd2e567d3fc8a7e89431b9a834
+
+Base: origin/main at 17c7894c5b5b334462de101b9be57cee2651e074
+
+Release criteria source: deployer prompt. No docs/PROJECT_MANIFEST.md or PROJECT_MANIFEST.md file exists in this checkout.
+
+## Summary
+
+PASS. This is a single-bead deploy for the census-owner-liveness doctor check and periodic alert wrapper. The candidate branch is one commit ahead of origin/main, conflict-free, review-passed, test-passed, and limited to one feature theme.
+
+## Criteria
+
+| # | Criterion | Verdict | Evidence |
+|---|-----------|---------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first and re-checked after the full test run. `git rev-list --left-right --count origin/main...HEAD` returned `0 1`; merge-base is `17c7894c5b5b334462de101b9be57cee2651e074`; `git merge-tree --write-tree origin/main HEAD` produced tree `f41aee5cdddcb49d164ccbd809d289c8c6dbbfd3` with no conflicts. |
+| 1 | Review PASS present | PASS | Review bead `ga-06zg1q` is closed with close reason `PASS`; notes contain `Review verdict: PASS` and `Verdict: PASS - routing to deployer`. |
+| 2 | Acceptance criteria met | PASS | Original build bead `ga-kr3glv.1` required a doctor check, a cron wrapper script, and an operator order snippet documented outside the repo. Candidate diff contains `cmd/gc/doctor_census_owner_liveness.go`, its tests, doctor registration/warmup/golden updates, and `scripts/check-census-owner-liveness.sh`. No in-repo order file was added, matching the non-goal. |
+| 3 | Tests pass | PASS | In scratch worktree `/var/tmp/codex-deployer-ga-joodpj-gate-20260716154637`: `bash -n scripts/check-census-owner-liveness.sh` passed; `shellcheck scripts/check-census-owner-liveness.sh` passed; `go vet ./...` passed; `go test ./cmd/gc/... -run 'CensusOwnerLiveness|WarmupEligible|DoctorChecks_NameSetUnchanged' -count=1` passed; `HOME=$(getent passwd "$(whoami)" \| cut -d: -f6) make test-fast-parallel` passed all 8 fast jobs. |
+| 4 | No high-severity review findings open | PASS | Review bead `ga-06zg1q` lists one primary finding already resolved by the builder follow-up before the PASS verdict. Remaining notes are informational/non-blocking; no unresolved HIGH finding is present. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` was clean before writing this gate file. The only pending change before commit is this release gate file. |
+| 7 | Single feature theme | PASS | `git diff --name-status origin/main...HEAD` touches one subsystem/theme: doctor registration/check/test/golden plus the census-owner-liveness wrapper script. Diff scope is 6 files, 537 insertions, 0 deletions. |

+
+## Gate Checklist
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | `git fetch origin main` succeeded. `git merge-tree --write-tree origin/main HEAD` returned tree `7cdd02781c3d691439a7b3aee1acd13120db8b51` with exit 0 and no conflicts. |
+| 1 | Review PASS present | PASS | `bd show ga-kn8yy6.2 --json` notes contain `REVIEW VERDICT: PASS` and `No blockers. Routing to deploy.` |
+| 2 | Acceptance criteria met | PASS | Verified the diff is the stated 9-file warmup extraction. `internal/warmup` contains `WarmupCheckResult`, `ScopeWarmupResult`, `WarmupReport`, `WarmupOpts`, `RunWarmupChecks`, and `CustomWarmupMail`. `cmd/gc/cmd_start_warmup.go` now contains only `defaultMailProvider`; `cmd/gc/cmd_start.go` builds doctor checks and calls `warmup.RunWarmupChecks`. The reviewed commit and deployed commit have the same stable patch ID. |
+| 3 | Tests pass | PASS | `go vet ./...` passed. Focused check passed: `go test ./internal/warmup ./cmd/gc -run 'TestRunWarmupChecks|TestDefaultMailProviderUsesStartedCityPath|TestBuildDoctorChecks_NameSetUnchanged'`. First `make test-fast-parallel` run hit the known shard-load timeout in `TestCityRuntimeRun_PanicInStartupDoesNotShutdownCity`; standalone rerun passed 3/3. Retried `make test-fast-parallel`; all fast jobs passed. |
+| 4 | No high-severity review findings open | PASS | Review bead notes contain no unresolved HIGH/request-change finding markers and explicitly state there are no blockers. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` was clean before writing this gate file; only this gate file is present for the gate commit. |
+| 7 | Single feature theme | PASS | Commit set is one refactor theme: move warmup runner/types from `cmd/gc` into `internal/warmup` so internal doctor producers can depend on the warmup report/mail contract without importing `cmd/gc`. Two test-only `fmt.Fprintf` cleanups in `cmd/gc` are mechanical lint fixes noted by the reviewer. |

+# Release Gate: exclude testing receiver environment/CWD helpers from resource census
+
+- Deploy bead: `ga-lay45s`
+- Source bead: `ga-njovi7`
+- Reviewed commit: `54c6a78785ac44c7e5bc102f6e2c99bb7e7d8333`
+- Deploy branch: `deploy/ga-lay45s-gate`
+- Current base: `origin/main@02831408893c86d49274611b37257cdbcc115870`
+- Merge base: `660b79166a4ab11dfedaa2b2ceac990a15874e2a`
+- Evaluated: 2026-07-25
+- Gate source: deployer prompt release-gate table. `docs/PROJECT_MANIFEST.md` is not present in this checkout.
+
+## Summary
+
+PASS. The resource census no longer charges `testing.T`/`testing.TB` receiver calls to `Setenv` and `Chdir` as ambient environment/CWD debt because those helpers restore state automatically. Direct `os.Setenv`, `os.Unsetenv`, `os.Clearenv`, and `os.Chdir` calls remain counted. The implementation, regression coverage, four exact-equality baseline rows, and generated ledger documentation form one resource-census policy change.
+
+## Criteria
+
+| # | Criterion | Verdict | Evidence |
+|---|-----------|---------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Checked first after fetching current `origin/main`. `git merge-tree --write-tree origin/main 54c6a78785ac44c7e5bc102f6e2c99bb7e7d8333` exited 0 and produced tree `8a82b52bf92350f4de1889bb311e0b783826b1d4`; `git diff --check origin/main...54c6a78785ac44c7e5bc102f6e2c99bb7e7d8333` produced no output. No self-rebase was needed. |
+| 1 | Review PASS present | PASS | The closed source bead `ga-njovi7` records an independent exact-SHA review ending in `Verdict: PASS`; the deploy bead reproduces that PASS evidence and identifies the reviewed commit. |
+| 2 | Acceptance criteria met | PASS | `matchedResourcesForCall` keeps direct `os.*` charging, excludes testing receiver `Setenv`/`Chdir`, and preserves fail-closed receiver-binding errors. `TestScanExcludesTestingReceiverSetenvChdirFromEnvironmentAndCWD` proves differential 1-not-2 counts for both resources. All four `cmd/gc+untagged` Debt/SmallDebt environment/CWD rows are lowered consistently in `bootstrapPolicy` and `test/test-resources.toml`; `TESTING.md` is regenerated and synchronized. No new resource/scope or key-specific exception was added. |
+| 3 | Tests pass | PASS | On the exact reviewed SHA, the focused regression and ledger-sync tests passed; the full `internal/testpolicy/resourcecensus/...` package passed; `go build ./...` and `go vet ./...` passed; `make test-fast-parallel` passed all 8 jobs on its first authoritative run. |
+| 4 | No high-severity review findings open | PASS | Source/deploy review notes contain no HIGH, request-changes, or security finding. The open-work query for `ga-lay45s`/`ga-njovi7` returned only the sling helper bead `ga-537678`. |
+| 5 | Final branch is clean | PASS | Before adding this gate file, `git status --short --branch` returned only `## HEAD (no branch)`. This gate file is the sole deploy-gate commit payload. |
+| 7 | Single feature theme | PASS | The six-file commit set is one resource-census policy change: classifier implementation and tests, exact baseline data, and the generated ledger projection. |
+
+## Acceptance Evidence
+
+- Testing receiver `Setenv`/`Chdir` excluded while direct `os.*` calls remain counted: PASS.
+- Fail-closed errors for unresolved receiver identifiers remain propagated: PASS.
+- Differential regression test covers both Environment and CWD: PASS.
+- Four `ScopeCmdGCUntagged` Debt/SmallDebt environment/CWD rows re-measured and synchronized: PASS.
+- Generated `TESTING.md` ledger matches source policy and TOML exactly: PASS.
+- Remaining migrations may add `t.Setenv`/`t.Chdir` calls without consuming the ambient resource ratchet: PASS by receiver-based classification and the differential regression.

+# Release Gate: NativeDoltStore Ready status filter
+
+Bead: `ga-nxmzl5`
+Implementation bead: `ga-3mv5d3`
+Branch: `builder/ga-3mv5d3-ready-status-filter`
+PR: https://github.com/gastownhall/gascity/pull/4347
+Reviewed commit: `2684ac560c730bf2e89092e669c31881b854d0c5`
+Base: `origin/main` at `4fda5a28445f42d6e789fc7f5751645ac4fecd19`
+
+The prompted `docs/PROJECT_MANIFEST.md` path is not present in this Gas City
+checkout. No `PROJECT_MANIFEST.md` or `SOFTWARE_FACTORY_MANIFEST.md` was found
+with `rg --files -g '*MANIFEST*.md' -g '!ga-*'`, so this gate uses the deployer
+release criteria from the role prompt and the repository testing guidance in
+`TESTING.md`.

+
+```text
+M	internal/beads/native_dolt_store.go
+M	internal/beads/native_dolt_store_test.go

+
+This is one release unit: `NativeDoltStore.Ready()` now queries only upstream
+statuses that can legitimately become dispatch candidates, and the matching
+regression test proves blocked/pinned/hooked/review/testing statuses do not
+surface as ready work after bd-status normalization.
+
+## Gate Checklist
+
+| # | Criterion | Result | Evidence |
+|---|---|---|---|
+| 1 | Review PASS present | PASS | `bd show ga-nxmzl5` records `Reviewed-by: gascity/reviewer, verdict PASS`; the implementation bead `ga-3mv5d3` is closed with the fix summary and verification notes. |
+| 2 | Acceptance criteria met | PASS | The regression test `TestNativeDoltStoreReadyOnlyIncludesOpenAndDeferredUpstreamStatuses` covers open, blocked, deferred, pinned, hooked, review, and testing upstream statuses. `nativeDoltOpenReadyStatuses` now contains only `beadslib.StatusOpen` and `beadslib.StatusDeferred`. The diff is limited to `internal/beads/native_dolt_store.go` and `internal/beads/native_dolt_store_test.go`, so the public `Bead.Status` wire enum, OpenAPI schema, and dashboard generated types are untouched. The implementation bead notes document the status-category investigation. |
+| 3 | Tests pass | PASS | `go test ./internal/beads -run TestNativeDoltStoreReadyOnlyIncludesOpenAndDeferredUpstreamStatuses -count=1` passed. `go test ./internal/beads/...` passed. `gofmt -l internal/beads/native_dolt_store.go internal/beads/native_dolt_store_test.go` returned no files. `go vet ./...` passed. `make test-fast-parallel` passed all 8 fast jobs. `gh pr checks 4347` was green at reviewed commit `2684ac560c730bf2e89092e669c31881b854d0c5` before adding this gate file. |
+| 4 | No high-severity review findings open | PASS | The deploy bead records reviewer PASS and no blocker/HIGH findings. PR #4347 has no comments or reviews from external contributors. |
+| 5 | Final branch is clean | PASS | Detached gate worktree at `/var/tmp/gc-deployer-ga-nxmzl5-pass-20260716-4eYigT` started clean at `origin/builder/ga-3mv5d3-ready-status-filter`; `git status --short --branch` returned only `## HEAD (no branch)` before this gate file was added. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-base --is-ancestor origin/main origin/builder/ga-3mv5d3-ready-status-filter` passed. `git merge-base origin/main origin/builder/ga-3mv5d3-ready-status-filter` returned `4fda5a28445f42d6e789fc7f5751645ac4fecd19`. `git merge-tree --write-tree origin/main origin/builder/ga-3mv5d3-ready-status-filter` succeeded with tree `34b5ba7dbc8f8b7efe7df1a5f4496464634b15fc`. |

+## Gate Results
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. `git merge-tree --write-tree origin/main 75b7395905b7d172d9e80ed4403d09e29235b0dd` exited 0 and produced tree `1e5c880d77664c4cbe4349bb2ab249935e162534`; `git diff --check origin/main...HEAD` exited 0. |
+| 1 | Review PASS present | PASS | `bd show ga-sj15c9` contains `Review verdict: PASS` for commit `75b739590`, with no blocking findings. |
+| 2 | Acceptance criteria met | PASS | Code inspection confirmed pinned always-mode sessions now require `persistRestart()` before promising a restart in both `gc handoff` and `gc runtime request-restart`; failures return 1 and suppress false restart messaging. `waitForControllerRestart` now returns success only when the restart flag is clear and `sp.IsRunning(sn)` is false. Regression and unit coverage exists in `cmd/gc/repro_ga_rble9w_test.go`, `cmd/gc/cmd_handoff_test.go`, `cmd/gc/cmd_runtime_drain_test.go`, and `cmd/gc/session_reconciler_restart_request_test.go`. |
+| 3 | Tests pass | PASS | `go test ./cmd/gc -run 'TestDoHandoff_PinnedAlwaysSessionRequiresPersistRestart|TestDoRuntimeRequestRestart_PinnedRequiresPersistRestart|TestDoHandoff_PinnedAlwaysSessionPersistsResetAndReconcilerStopsSession|TestRepro_ga_rble9w_PinnedMayorHandoffNeverCyclesAndFalselyReportsSuccess|TestWaitForControllerRestartHandoffFlagClearedButSessionStillRunning'` passed. `make test-fast-parallel` passed all 8 fast jobs. `go vet ./...` passed. `go build ./...` passed. |
+| 4 | No high-severity review findings open | PASS | Review notes for ga-sj15c9 record PASS. The only follow-up, ga-e17tpz, is explicitly non-blocking and pre-existing: `gc handoff --target` direct-kill behavior is outside this fix's self-handoff/request-restart scope. |
+| 5 | Final branch is clean | PASS | Isolated worktree `/var/tmp/codex-gascity-ga-pms9ox-gate-3554070` was clean before this gate file; after the gate commit, `git status --short --branch` is expected to show only `## deploy/ga-pms9ox-gate`. |
+| 7 | Single feature theme | PASS | Single commit touches only `cmd/gc` handoff/runtime restart behavior and adjacent tests: `cmd_handoff.go`, `cmd_runtime_drain.go`, and related `cmd/gc` tests. No independent subsystem or unrelated user-facing behavior is bundled. |
+
+## Acceptance Detail
+
+- Pinned self-handoff no longer claims success when the persistent restart marker is unavailable.
+- `gc runtime request-restart` follows the same pinned-session requirement.
+- A cleared `GC_RESTART_REQUESTED` flag is no longer treated as proof of restart while the session is still running.
+- Non-pinned restart behavior remains best-effort for the persisted bead marker and is covered by the existing passing command tests.

+
+## Gate Results
+
+Criterion 6 was evaluated first as required.
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Source review bead `ga-xy2gbc` is closed with `REVIEW VERDICT: PASS`. The independent review covered the complete diff, build, vet, focused tests, security, coverage, CI integrity, and the parent-bead sequencing constraint. |
+| 2 | Acceptance criteria met | PASS | The patch explicitly pins `GC_CITY_PATH` at 26 `main_test.go` sites, one `cmd_nudge_test.go` site, and five `cmd_formula_test.go` sites. `SetupHermeticCookEnv` now separates its working directory from the exact city root, and both repo-wide callers pass the correct pair. All 36 directly affected, indirectly affected, and guard-blind control tests passed. No production code changed. |
+| 3 | Tests pass | PASS | On gated commit `eabb4f7c7`, `go build ./...` and `go vet ./...` passed; all 36 focused tests passed; and `make test-fast-parallel` passed all nine jobs (`unit-core`, six `unit-cmd-gc` shards, `fsys-darwin-compile`, and `push-gate-lock-selftest`). |
+| 4 | No high-severity review findings open | PASS | The source review records only two non-blocking bookkeeping nits: the original base attribution and a verification-count typo. It records no unresolved HIGH, security, coverage, or CI-integrity finding. Deployer inspection found no additional high-severity concern in this test-only change. |
+| 5 | Final branch is clean | PASS | Before this checklist was added, `git status --porcelain` produced no output, `git diff --check origin/main..HEAD` passed, and `gofmt -l` produced no output for all four changed files. This checklist is committed as the isolated deploy branch tip. |
+| 6 | Branch diverges cleanly from main | PASS | The reviewed commit did not contain current main, so the canonical bounded helper replayed it from `48a40cd9ab` to `eabb4f7c77` on `origin/main@1bc6427272`. `git range-diff` reported the patch as identical, the lease-protected push to the isolated deploy branch succeeded, `git ls-remote` verified the remote at `eabb4f7c771b464f5b09864f71671d5b2e69bc12`, and a final fetch confirmed current main is its ancestor. |
+| 7 | Single feature theme | PASS | The commit changes three `cmd/gc` test files and their shared test helper for one purpose: make city selection explicit instead of relying on ambient upward discovery. |
+
+## Acceptance Checks
+
+- PASS: Twenty-six prime/session-hook test sites in `cmd/gc/main_test.go` pin
+  their temporary city explicitly.
+- PASS: `TestCmdSessionNudgeQueueResolvesSessionName` pins its temporary city
+  explicitly.
+- PASS: Three direct formula-cook sites pin their city explicitly.
+- PASS: Both formula-cook helper call sites preserve cwd-based rig selection
+  while passing the exact city root through `GC_CITY_PATH`.
+- PASS: `SetupHermeticCookEnv` has exactly two repo-wide callers, and both use
+  the new `chdirDir, cityRootDir` contract.
+- PASS: The change remains test-only: 48 insertions and 7 deletions across
+  three test files and `internal/formulatest/env.go`.
+- PASS: Parent bead `ga-klo4gz` remains sequenced after the full migration;
+  this batch does not clear the ambient-discovery guard to land.

+- Manifest note: `docs/PROJECT_MANIFEST.md` is not present in this checkout; this gate uses the deployer release criteria and the local `TESTING.md` gates.
+- Follow-up rebase note: this is the second rebase of this PR (bead `ga-u4vkyp`, filed by the hourly pr-audit order after PR #4351 drifted back into conflict following the prior `ga-7amgxo` rebase). `origin/main` advanced from `ed3d0626f5` to `aa0c20af55` between the two rebases; the only re-conflicting file set was again the resource-census ratchet triple.
+
+## Summary
+
+PASS. The branch is current with `origin/main`, reviewer PASS is present, the
+acceptance criteria are covered by code and tests, and the release-gate test
+suite passed in the deployer worktree.
+
+## Evidence
+
+- `git rev-parse origin/main`: `aa0c20af554ae75cd6a53cce5434f201e2e39c9f`
+- `git rev-parse HEAD`: `d5f5aee4447654cdc751832e7adeab13b6272ef8`
+- `git rev-parse origin/builder/ga-478c0o-reaper-clean-deploy-v6` (pre-push): `b9a37c8f08d346878cbf336034dfff295829a52d`
+- `git rev-list --left-right --count origin/main...HEAD`: `0 9`
+- `git rev-list --left-right --count origin/builder/ga-478c0o-reaper-clean-deploy-v6...HEAD`: `8 71` (origin's PR branch predates this self-rebase onto newer `main`; all feature commits are carried forward with identical content under new SHAs, plus the additional `main` commits pulled in by the rebase)
+- `git merge-tree --write-tree origin/main HEAD`: `d9379eb609aaff9d1316deaaaa62db772c224bec` (clean, no conflict markers)
+- `git config core.hooksPath`: `.githooks`
+- `scripts/rebase-resolve-lib.sh`: absent; this refresh required a real self-rebase onto `origin/main` (PR had drifted to `mergeStateStatus: DIRTY` / `mergeable: CONFLICTING` per `gh pr view` again, after the prior rebase's target `origin/main` advanced further). Conflicts were again limited to the resource-census ratchet triple (`internal/testpolicy/resourcecensus/census.go`, `test/test-resources.toml`, `TESTING.md`). Per the same protocol as the prior rebase, the correct baseline was confirmed by running `TestRepositoryLedgerMatchesCensusAndDocumentation` rather than guessing: an initial take-HEAD resolution (533 calls / 158 files) was falsified by the test (`resource ledger drift: ... calls=534 (baseline 533), files=159 (baseline 158)`), so the baseline was bumped to the test-reported `534` calls / `159` files, propagated identically to all three files, and re-verified green. The `take-HEAD` interim resolution also produced an empty replay for the original ledger-bump commit, which git auto-skipped during `rebase --continue`; the real 534/159 bump was carried by a fresh commit (`d5f5aee44`, "test(resourcecensus): rebase ledger bump onto origin/main") so the branch still carries 9 commits above `origin/main`, matching the original PR's commit count.

+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Scoped fetches refreshed `origin/main` and the candidate branch. `rev-list` is `0 9`, `merge-tree --write-tree` against `origin/main` completed conflict-free at `d9379eb609aaff9d1316deaaaa62db772c224bec`. |
+| 1 | Review PASS present | PASS | Parent review bead `ga-trvdd9` is closed with `REVIEW VERDICT: PASS`; deploy bead carries `source:actual-reviewer`. |
+| 2 | Acceptance criteria met | PASS | Reviewer verified the four mayor criteria: confirmed-orphan datadir removal gated on classification, symptom-based old `.dolt` store-dir sweep with lsof fail-closed behavior, SIGKILL leak-guard integration coverage, and no shell backstop removed. Deployer re-ran the relevant suites below. |
+| 3 | Tests pass | PASS | `go build ./...`; `go vet ./...`; `go test ./internal/testpolicy/resourcecensus/... ./internal/doltorphan/... ./test/dolttest/...`; `go test -tags integration ./examples/gastown/... -run TestSweep_ReapsRealDoltDataDirAfterSIGKILL -count=1`; and `HOME=/home/jaword make test-fast-parallel` all passed. Note: this rebase's `make test-fast-parallel` run hit one failure in shard `unit-cmd-gc-4-of-6`: `TestProductMetricsLifecycleFailuresPreserveOutputAndOTel/JSONL_failure/factory_error`, a known live-event-store race unrelated to this diff (the test and the code it exercises are both untouched by `git diff origin/main...HEAD`). Two isolated re-runs of that test alone (`go test -count=1 ./cmd/gc/... -run TestProductMetricsLifecycleFailuresPreserveOutputAndOTel`) both passed cleanly, confirming the flake rather than a regression. |
+| 4 | No high-severity review findings open | PASS | Reviewer recorded no blocking correctness, security, or style findings. The only noted residual TOCTOU race is non-blocking and narrowed by age/lsof gates. |
+| 5 | Final branch is clean | PASS | Worktree was clean before refreshing this gate file; this gate file is committed as the final branch tip and `git status` is clean after commit. |
+| 7 | Single feature theme | PASS | All changes are one release theme: removing leaked Dolt data dirs and adding the test-only orphan store-dir sweep, with supporting tests and resource-census baseline updates. |

+empty for both). Two isolated re-runs of the test alone, back to back, both
+passed cleanly — confirming a pre-existing flake, not a regression. The prior
+rebase's gate refresh independently hit and cleared the same class of
+`$HOME`-sensitive-environment issue (a different test,
+`TestProductMetricsServiceChildEnvSupervisorStart`, guarded by
+`platformSupervisorHomeOverrideError` in `cmd/gc/cmd_supervisor_lifecycle.go`);
+this run already used the real user `HOME` throughout, so that specific
+guard did not trip this time.

+Date: 2026-07-14
+
+## Summary
+
+This gate evaluates a single test-only change to `examples/bd/dolt/compact_real_dolt_test.go`: the real-Dolt compact integration test now builds under the repository's broad `integration` tag as well as the narrower `dolt_integration` tag.
+
+`docs/PROJECT_MANIFEST.md` is not present in this checkout, so the deployer seven-criterion release gate is the operative checklist.
+
+## Checklist
+
+| # | Criterion | Result | Evidence |
+|---|---|---|---|
+| 1 | Review PASS present | PASS | Deploy bead states "Reviewed + PASSED by reviewer gascity/reviewer"; source bead `ga-29lmx5` is referenced in the deploy bead. |
+| 2 | Acceptance criteria met | PASS | The only code delta changes the build constraint from `//go:build dolt_integration` to `//go:build integration || dolt_integration`, matching the intended behavior. Targeted tests passed under both tags. |
+| 3 | Tests pass | PASS | `go test -tags integration ./examples/bd/dolt/... -run TestCompactScriptRealDoltRemotePush -count=1` passed. `go test -tags dolt_integration ./examples/bd/dolt/... -run TestCompactScriptRealDoltRemotePush -count=1` passed. `TMPDIR=/tmp/gtg make test-fast-parallel` passed all 8 shards. `TMPDIR=/tmp/gtg go vet ./...` passed. `gofmt -l examples/bd/dolt/compact_real_dolt_test.go` produced no output. |
+| 4 | No high-severity review findings open | PASS | No open HIGH findings are recorded in the deploy bead. The reviewed change is a one-line test build-tag fix with no production or security surface. |
+| 5 | Final branch is clean | PASS | `git status --short --branch` was clean before adding this gate file; this checklist is the only deployer-added file and is committed as the branch tip. |
+| 6 | Branch diverges cleanly from main | PASS | `git rev-list --left-right --count origin/main...origin/builder/ga-tnaipt-wire-dolt-integration-tag` returned `0 1`. `git merge-tree --write-tree origin/main origin/builder/ga-tnaipt-wire-dolt-integration-tag` succeeded with tree `9f9aa9f9956f841503cc2080fb0ed5b53657cd9e`. |
+| 7 | Single feature theme | PASS | The commit touches only `examples/bd/dolt/compact_real_dolt_test.go`; the branch has one test-infrastructure theme. |
+
+## Notes
+
+An initial `make test-fast-parallel` run used a long `/var/tmp/gotmp-ga-tyghvn-fast2...` path and failed in cmd/gc shards because Unix socket paths exceeded platform limits (`bind: invalid argument`) and controller-poke tests timed out. Rerunning the same fast gate with the short `TMPDIR=/tmp/gtg` path passed all shards. `/tmp` had sufficient free space before the short-path rerun.

+| 6 | Branch diverges cleanly from main | PASS | Checked first. `git fetch origin main`; `git merge-tree --write-tree origin/main 7ae5019665b0308efc094d0075bd761899ed69bf` returned tree `d42820b74c32c3f735635c3c77db6dbbb5b6d609`; `git diff --check origin/main...7ae5019665b0308efc094d0075bd761899ed69bf` produced no output. |
+| 1 | Review PASS present | PASS | Deploy bead `ga-ubq2x1` records reviewer PASS for source bead `ga-z7evh4.2`; source notes contain `REVIEWER VERDICT: PASS`. |
+| 2 | Acceptance criteria met | PASS | Commit set is a single commit, `7ae501966`, touching only `test/docsync/docsync_test.go` (+15/-0). Source notes and direct diff confirm no stranded routed-demand or throttle changes are included. |
+| 3 | Tests pass | PASS | `go test ./test/docsync/... -run TestDocDirCoverage -count=1 -v` passed; `go test ./test/docsync/... -count=1` passed; `go vet ./test/docsync/...` passed; `go build ./...` passed; `go vet ./...` passed; `make test-fast-parallel` passed all 8 fast jobs. |

+# Release gate - PG-auth warmup mail producer (ga-uslskt.3)
+
+**Verdict:** PASS
+
+- Bead: `ga-uslskt.3`
+- Source branch: `builder/ga-uslskt-postgres-auth-warmup-mail`
+- Reviewed HEAD: `a054b971f0188bd67abd7bd1d8ec111d38446352`
+- Base checked: `origin/main` at `9ddbea5c0b4b3cebf09fc36c0f88a8c52f9dd991`
+- Manifest note: `docs/PROJECT_MANIFEST.md` is not present in the Gas City worktree; this gate applies the deployer prompt's seven release criteria.
+
+## Criteria
+
+| # | Criterion | Verdict | Evidence |
+|---|-----------|---------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. `git merge-tree --write-tree origin/main origin/builder/ga-uslskt-postgres-auth-warmup-mail` returned tree `cd5bcac437dd2b3cdc1d162e72d1b6c56809f169` with exit 0. Branch is 6 behind / 2 ahead of `origin/main`; no merge conflicts. |
+| 1 | Review PASS present | PASS | Review bead `ga-uslskt.2` is closed with `Review verdict 2026-07-19 (gascity/reviewer): PASS`; review notes report no blocking findings. |
+| 2 | Acceptance criteria met | PASS | `PostgresAuthCheck.WarmupEligible()` returns true; `WarmupMailSubject` is exactly `postgres-auth alert during city warm-up`; `SoleFailureMail` implements the PG-auth sole-failure body with deterministic severity/scope sorting and fixed footer. The already-landed warmup runner extension is present on this branch: `CustomWarmupMail`, `tryCustomSoleFailureMail`, generic fallback on mixed checks, defensive-copy isolation, and 4096-byte truncation. The five PG-auth-specific test additions are intentionally split to follow-up deploy bead `ga-xawilr`, which is blocked on this deploy per `ga-uslskt.3` instructions. |
+| 3 | Tests pass | PASS | `go build ./...` passed. `go vet ./...` passed. `go test ./internal/doctor/... ./internal/warmup/...` passed. `make test-fast-parallel` passed all 8 fast jobs. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes identify both scrutinized items (package move and severity sort) as correct, with no blocking or high-severity findings open. |
+| 5 | Final branch is clean | PASS | Scratch worktree at reviewed HEAD was clean before gate-file creation (`git status --short --branch` reported only detached HEAD). The gate file is the only deployer-authored delta and is committed as the release-gate commit. |
+| 7 | Single feature theme | PASS | The commit set touches one subsystem/theme: PG-auth doctor check registration and warmup mail behavior. Diff paths are `cmd/gc/cmd_doctor.go`, `internal/doctor/checks/postgres_auth.go`, `internal/doctor/checks/postgres_auth_test.go`, `internal/doctor/checks/testenv_import_test.go`, and `internal/doctor/warmup_eligible.go`. |
+
+## Validation
+
+- `git fetch origin main builder/ga-uslskt-postgres-auth-warmup-mail` - PASS
+- `git ls-remote origin refs/heads/builder/ga-uslskt-postgres-auth-warmup-mail refs/heads/main` - confirmed remote branch at `a054b971f0188bd67abd7bd1d8ec111d38446352` and main at `9ddbea5c0b4b3cebf09fc36c0f88a8c52f9dd991`
+- `git merge-tree --write-tree origin/main origin/builder/ga-uslskt-postgres-auth-warmup-mail` - PASS, no conflicts
+- `go build ./...` - PASS
+- `go vet ./...` - PASS
+- `go test ./internal/doctor/... ./internal/warmup/...` - PASS
+- `make test-fast-parallel` - PASS, all fast jobs passed
+
+## Review Notes
+
+The PR should call out that this moves `PostgresAuthCheck` into `internal/doctor/checks` to avoid the `doctor -> warmup -> doctor` import cycle while keeping registration in `cmd/gc/cmd_doctor.go`. It should also call out that the dedicated PG-auth test-coverage follow-up is separate and blocked on this implementation landing.

+# Release Gate: ga-v6j6f4 control-ready dispatch
+
+Date: 2026-07-14
+
+Branch under gate: `origin/deploy/ga-v6j6f4.1-control-ready-clean`
+
+Gate worktree: `/var/tmp/gascity-deploy-ga-v6j6f4-current.ZdtHzK`
+
+Head under gate: `814adbd4722d9c13fa59085c9c0c521e5ee609aa`
+
+Base checked: `origin/main` at `a4046035b08e9f18f3e761371440da40cd70b12a`
+
+Release criteria source: `docs/PROJECT_MANIFEST.md` is not present in this checkout, so this gate uses the release criteria from the active deployer prompt loaded by `gc prime`, plus `TESTING.md`.
+
+## Change Summary
+
+This branch keeps the control-dispatcher readiness scan from fork-execing `bd` once per candidate/route on every tick. `nextWorkflowServeBeads` now recognizes the existing control-ready query shape and answers it from an in-process `CachingStore` snapshot when possible. If the cache cannot answer, the fallback is a single batched `bd ready --json` call followed by the same Go-side candidate/route filtering.
+
+The branch also carries a dedicated test-policy baseline bump for the new `t.Setenv` calls in the control-ready dispatch tests. The bump updates the three files that resourcecensus keeps in sync: `internal/testpolicy/resourcecensus/census.go`, `test/test-resources.toml`, and `TESTING.md`.
+
+## Commit Set
+
+| Commit | Summary |
+| --- | --- |
+| `5be4a4135` | `fix(dispatch): serve control-dispatcher readiness from CachedReady instead of per-agent bd fork-execs` |
+| `456a46b84` | `fix(dispatch): raise control-ready fallback limit and log truncation (ga-bbj6wv)` |
+| `814adbd47` | `test(resourcecensus): bump environment baseline for control-ready dispatch tests (ga-v6j6f4.1)` |
+
+## Diff Scope
+
+`git diff --name-status origin/main...HEAD`:
+
+```text
+M	TESTING.md
+A	cmd/gc/dispatch_control_ready.go
+A	cmd/gc/dispatch_control_ready_test.go
+M	cmd/gc/dispatch_runtime.go
+M	internal/beads/query.go
+M	internal/testpolicy/resourcecensus/census.go
+M	test/test-resources.toml
+```
+
+The previous gate failed criterion 7 because the original branch also carried unrelated ReadyGraphOnly/beads commits. This isolated branch does not touch those rejected-scope files.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+| --- | --- | --- | --- |
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. `git merge-tree --write-tree origin/main HEAD` returned exit 0 and wrote tree `9593583f15953dafe3a34b07ebb15e10286b7568`; no merge conflicts with current `origin/main`. |
+| 1 | Review PASS present | PASS | Review bead `ga-bbj6wv` is closed with `Reviewer verdict: PASS (re-review)`. The reviewer confirmed Finding 1 fixed by the fallback limit/logging change and Finding 2 addressed by documentation. |
+| 2 | Acceptance criteria met | PASS | `ga-ak6rt1` done-when is met: clean-cache readiness is served from `CachedReady`, dirty/unprimed compatibility uses one batched fallback call, candidate precedence and legacy/bare routing are covered by tests, and `rg -n 'Mayor|Deacon|Polecat|mayor|deacon|polecat'` over touched Go files returned no matches. |
+| 3 | Tests pass | PASS | First `TMPDIR=/var/tmp GOTMPDIR=/var/tmp make test-fast-parallel` failed only `TestSessionReconcilerTraceGH1654WorkRequestedStartCandidates/named_session_post-kill` with `async starts did not finish`; exact subtest rerun passed. Second full `TMPDIR=/var/tmp GOTMPDIR=/var/tmp make test-fast-parallel` passed all fast jobs. `TMPDIR=/var/tmp GOTMPDIR=/var/tmp go vet ./...` also passed. |
+| 4 | No high-severity review findings open | PASS | Review notes list one Medium and one Low finding; both are resolved in the PASS re-review. No HIGH finding appears in `ga-bbj6wv` or `ga-v6j6f4.3` notes. |
+| 5 | Final branch is clean | PASS | Before writing this gate file, `git status --short --branch` returned only `## HEAD (no branch)`. This checklist is the only deployer-created file and will be committed as the final branch tip before PR creation. |
+| 7 | Single feature theme | PASS | Commit set is one feature theme: control-dispatcher readiness source and directly supporting tests/resourcecensus baselines. The diff is limited to `cmd/gc` dispatch readiness, `internal/beads` ready ordering export, and synchronized test policy baseline files. |
+
+## Test Evidence
+
+```text
+TMPDIR=/var/tmp GOTMPDIR=/var/tmp make test-fast-parallel

+# Release Gate: Playwright Chromium cold-cache timeout hardening
+
+Bead: `ga-xb94fi`
+Source bead: `ga-bt679z`
+Deploy branch: `deploy/ga-xb94fi-gate`
+Deploy source: `de92acf33a5a4782ecbda75fa875bf75f06acf39`
+
+Result: PASS
+
+Note: the deploy bead description still names the stale pre-rebase source
+`ebd23371b`. The bead notes contain a verified builder handoff updating the
+deploy source to `de92acf33a5a4782ecbda75fa875bf75f06acf39`; this gate was run
+against that updated source.
+
+## Evaluation Order
+
+Criterion 6 was evaluated first per deployer instructions.
+
+- `git fetch origin main`: PASS.
+- `git rev-parse origin/main`: `7e6ad17b311ba3776b4273471d0b51c70e8a6863`.
+- `git merge-base origin/main de92acf33a5a4782ecbda75fa875bf75f06acf39`:
+  `cdb1b4260f962519b2313a3e495a1cc158f893e2`.
+- `git merge-tree --write-tree origin/main de92acf33a5a4782ecbda75fa875bf75f06acf39`:

+
+No bounded self-rebase was needed.
+
+## Scope
+
+Commit set:
+
+- `868cccd19` - `fix(ci): harden Playwright Chromium install against cold-cache timeouts`
+- `de92acf33` - `chore(cipolicy): update pinned CI execution hash for Playwright cache fix`
+
+Changed paths:
+
+- `.github/workflows/ci.yml`
+- `scripts/cipolicy/policy.go`
+
+`git diff --stat origin/main...HEAD` reports exactly 2 files changed, 23
+insertions, 5 deletions.
+
+## Gate Checklist
+
+| # | Criterion | Status | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. `git merge-tree --write-tree origin/main de92acf33a5a4782ecbda75fa875bf75f06acf39` returned tree `b9bb2cb2aa3f4adde5b000c2a1da8b07a5e3743d` with no conflicts. |
+| 1 | Review PASS present | PASS | `bd show ga-bt679z` contains `Reviewer re-review verdict: PASS`; source bead `ga-bt679z` is closed with reason `pass`; deploy bead `ga-xb94fi` records reviewer PASSED status. |
+| 2 | Acceptance criteria met | PASS | `ci.yml` splits Playwright cache restore/save, uses `actions/cache/restore` before install and `actions/cache/save` with `if: always()` after install, preserves the same pinned cache SHA and key, wraps install in a 3-attempt retry with 10s/20s backoff, raises install timeout from 5 to 12 minutes, and updates the CI policy execution hash. Follow-up `ga-8e0ukr` tracks the out-of-scope cache-quota root cause. |
+| 3 | Tests pass | PASS | `python3 yaml.safe_load` on `.github/workflows/ci.yml` PASS; `go test ./scripts/cipolicy/...` PASS; `go test ./scripts/... -run TestPushOwnershipGuard -v` PASS; `make test-ci-policy` PASS; `go build ./cmd/gc/` PASS; `make test-fast-parallel` PASS (`All fast jobs passed`); `go vet ./...` PASS. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes say all done-when criteria are met with no outstanding blockers; `bd search "ga-bt679z HIGH"`, `bd search "ga-xb94fi HIGH"`, and `bd search "Playwright Chromium high severity"` returned no matching issues. |
+| 5 | Final branch is clean | PASS | Before committing this gate file, `git status --short --branch` showed only `?? release-gates/ga-xb94fi-playwright-chromium-cache-timeout-gate.md`; final clean status is rechecked after the gate commit before push. |
+| 7 | Single feature theme | PASS | The two-commit set touches one subsystem/theme: Dashboard SPA CI Playwright Chromium install hardening and the corresponding CI policy hash update. |
+
+## Manifest Note
+
+`docs/PROJECT_MANIFEST.md` is not present in this worktree, so no additional
+repo-specific release criteria were available from that path. The gate used the
+deployer release criteria and the repo testing guidance in `TESTING.md`.

+# Release Gate: ga-xh2brv
+
+Bead: ga-xh2brv
+Source bead: ga-u8h4ql
+Reviewed commit: 7dc6d862e839fec6df83f21d213ac4dc684c1378
+Deploy branch: deploy/ga-xh2brv-gate
+Deploy source commit: b0713c362698f4463d9704d0b0fcac0afb9fcf06
+Base checked: origin/main c967f1eebef64fe1ad4d9d287fd778fcd796f640
+Project manifest: docs/PROJECT_MANIFEST.md not present in this repository checkout; evaluated against the deployer prompt's gate table, TESTING.md, and the Makefile fast-suite target.
+
+Prior attempt: this gate file previously FAILed at local (unpushed) commit
+`ac2a8ce0d6978c1d15431a3bfc8076fb117f8d07` on criteria 2 and 3. Criterion 2:
+with only `internal/api/openapi.json` staged, the reviewed hook exited at the
+existing go/web/docs early guard before `spec_changed` was computed, so
+client generation and staging never ran for a spec-only commit; the original
+static test missed this control-flow path. Criterion 3: `make
+test-fast-parallel` passed 7/8 shards but `TestCmdStopWallClockTimeoutBoundsDirectStop`
+exceeded its near-100ms cap (1.230021478s) under sharded load. No deploy
+branch was pushed and no PR was opened for that attempt; the failure was
+routed to `gascity/builder` (sling auto-convoy ga-dlknrr). Both are fixed on
+this branch (commits `18f8521ed`, `8b321e034`, `cb4051f0d`) and independently
+re-verified below.
+
+Content-identity check: the originally reviewed change
+(`.githooks/pre-commit`, `scripts/precommit_contract_test.go`) is
+byte-for-byte identical between reviewed commit `7dc6d862e` and this
+branch's re-derived commits (`d9c19d1be`, `f89f890b7`) — confirmed via
+`diff <(git show 7dc6d862e:<file>) <(git show f89f890b7:<file>)`, empty for
+both files. The review's PASS verdict covers the exact code being deployed;
+it was only rebased onto a later `main` tip, not reimplemented.
+
+Stable patch-id for the feature files:

+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Source bead ga-u8h4ql notes contain `REVIEW VERDICT: PASS (reviewer: gascity/reviewer, 2026-07-25T14:41:13Z)` for reviewed commit `7dc6d862e839fec6df83f21d213ac4dc684c1378`. Content-identity check (above) confirms this branch carries that exact reviewed diff. |
+| 2 | Acceptance criteria met | PASS | Prior FAIL fixed by `8b321e034` (computes `spec_changed` before the early-guard branch so a spec-only-staged commit still regenerates the client). Regression covered by new test `TestPreCommitReachesDashboardBlockWhenOnlySpecFileStaged` (`18f8521ed`), re-run standalone: PASS (0.38s). Sibling test `TestPreCommitRegeneratesDashboardClientOnSpecChange` re-run: PASS. |
+| 3 | Tests pass | PASS | Prior FAIL fixed by `cb4051f0d` (widens `TestCmdStopWallClockTimeoutBoundsDirectStop`'s latency bound). Re-run 3x standalone: PASS each time (0.15s, 0.14s, 0.14s). `go vet ./...` clean. `go build ./cmd/gc/` exit 0. `make test-fast-parallel`: all 8 fast jobs passed, confirmed via 3 independent fresh runs this session against the current working tree (including the census-ledger fix). |
+| 4 | No high-severity review findings open | PASS | ga-u8h4ql reviewer notes: OWASP walk finds no findings (A08 improved, no injection surface, only hardcoded commands). One minor non-blocking observation (no end-to-end hook-execution test) explicitly flagged "not a blocker." CI-fix-integrity check confirmed the reviewer's own pre-push flake dismissal was legitimate (diff scope excludes cmd/gc). No HIGH findings anywhere in the notes. |
+| 5 | Final branch is clean | PASS | `git status --porcelain=v2 --branch` clean before writing this gate file. |
+| 6 | Branch diverges cleanly from main | PASS | `git merge-tree --write-tree origin/main HEAD` exited 0, produced tree `f11a10ce5c2d0846158921a0be0b1c4e5b598d0f`. |
+| 7 | Single feature theme | PASS | Full diff vs `origin/main` is 7 files: `.githooks/pre-commit`, `scripts/precommit_contract_test.go`, `cmd/gc/cmd_stop_test.go`, `internal/testpolicy/resourcecensus/census.go`, `test/test-resources.toml`, `TESTING.md`, and this gate document (`release-gates/ga-xh2brv-precommit-dashboard-client-generation-gate.md`). All directly serve one theme: land the dashboard-client-generation hook fix, its regression test, the flaky-test bound that test's related suite run surfaced, and the resource-census ratchet the new test's 2 `exec.Command` call sites require. |

+Base: origin/main at 4fda5a28445f42d6e789fc7f5751645ac4fecd19
+Gate result: PASS
+
+Release criteria source: docs/PROJECT_MANIFEST.md is not present in this

+deployer prompt's release-gate criteria table.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 6 | Branch diverges cleanly from main | PASS | Checked first. `git ls-remote origin refs/heads/main refs/heads/builder/ga-igcny0.1.2-clone-local-metadata` matched local refs. `git rev-list --left-right --count origin/main...origin/builder/ga-igcny0.1.2-clone-local-metadata` returned `0 1`; `git merge-base --is-ancestor origin/main origin/builder/ga-igcny0.1.2-clone-local-metadata` exited 0; `git merge-tree --write-tree origin/main origin/builder/ga-igcny0.1.2-clone-local-metadata` exited 0 with tree `16a11af03ec4406adb419324010f59a4b1431f50`. |
+| 1 | Review PASS present | PASS | Source review bead `ga-igcny0.1.2.2` is closed with `REVIEW VERDICT: PASS`. Reviewer evidence includes build, vet, gofmt, golangci-lint, `make test-fast-parallel`, targeted Store/local-sidecar tests, reconciler composition tests, full `internal/api`, and OWASP walk-through with no findings. |
+| 2 | Acceptance criteria met | PASS | The branch adds `Store.SetLocalString` / `Store.GetLocalString`, implements them across Store implementations and wrappers, adds shared Store conformance coverage, persists BdStore/NativeDoltStore clone-local data via `localSidecar`, keeps MemStore/FileStore/exec.Store clone-local behavior local, and adds reconciler composition tests proving clone-local keys do not leak into durable metadata or interfere with `SetMarker` / pending-create metadata. No relationship to `ga-yufa.4` is introduced. |
+| 3 | Tests pass | PASS | Ran on scratch worktree `/var/tmp/gascity-deployer-ga-xy1ssk-gate.RsuWo6`: `go build ./...`; `go vet ./...`; `gofmt -l .` (empty); `go test ./internal/beads/...`; `go test ./cmd/gc/... -run 'LocalString|LocalMetadata'`; `go test ./internal/api/...`; `make test-fast-parallel` (all 8 fast jobs passed); `make dashboard-check` (dashboard build, typecheck, test targets passed). |
+| 4 | No high-severity review findings open | PASS | Reviewer notes for `ga-igcny0.1.2.2` report no security findings and only two non-blocking observations. `bd search "ga-igcny0.1.2.2 HIGH" --json` returned `[]`. |
+| 5 | Final branch is clean | PASS | Scratch candidate worktree was clean before adding this gate file: `git status --short --branch` returned only `## HEAD (no branch)` after moving the temporary deploy log outside the checkout. This gate file is the only release-gate addition to commit. |
+| 7 | Single feature theme | PASS | Single commit `0c2251908` touches one subsystem theme: clone-local Store metadata plumbing and tests. Touched files are limited to Store implementations/wrappers, local sidecar tests, reconciler composition tests, and one API test wrapper update required by the Store interface. No independent user-facing feature is bundled. |
+
+## Notes
+
+- `gh auth status` passed for account `quad341`.
+- `gh pr list --head builder/ga-igcny0.1.2-clone-local-metadata --state all --json number,url,state,author,title,headRefOid` returned `[]`; no existing PR was touched.
+- `docs/PROJECT_MANIFEST.md` and any `PROJECT_MANIFEST.md` were absent from this worktree, so no additional project-manifest release criteria could be evaluated.

+| 6 | Branch diverges cleanly from main | PASS | Evaluated first. `git fetch origin main` succeeded. `git rev-list --left-right --count origin/main...origin/gc-builder-3-y8xzok-v2` returned `0 1`. `git merge-tree --write-tree origin/main origin/gc-builder-3-y8xzok-v2` exited 0 with tree `1a246ea3da4809e711712da2f0460af87d4866c0`. |
+| 1 | Review PASS present | PASS | Review bead `ga-h3h0c2` is closed with `REVIEW VERDICT: PASS` and states no actionable defects were found. |
+| 2 | Acceptance criteria met | PASS | The new `engdocs/contributors/hold-label-conventions.md` names the allowed hold labels, explains dependency edges vs. blocked status vs. hold labels, lists retired labels with replacement/no-op rules, includes `hold:external` and `hold:mayor`, and explicitly states this is a data convention rather than SDK behavior. `git grep` found no `hold:mayor`, `hold:external`, or retired hold-label literals in non-test Go under `cmd/gc` or `internal`. |
+| 3 | Tests pass | PASS | `make check-docs` passed (`go test ./test/docsync`). `go vet ./...` passed. `HOME=/home/jaword make test-fast-parallel` passed all 8 fast jobs. |
+| 4 | No high-severity review findings open | PASS | Review bead `ga-h3h0c2` records PASS, OWASP/security N/A for docs-only content, and no actionable defects. No high-severity finding remains open in the review notes. |
+| 5 | Final branch is clean | PASS | Scratch worktree started clean at candidate commit. `git diff --check origin/main...HEAD` passed before adding this gate file. |
+| 7 | Single feature theme | PASS | Single commit and three-file docs-only diff: `AGENTS.md`, `engdocs/contributors/index.md`, and `engdocs/contributors/hold-label-conventions.md`, all for the hold/blocked label taxonomy documentation. |

+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Deploy bead description records `Reviewed + PASSED by reviewer gascity/reviewer` after re-review; labels include `source:actual-reviewer`. |
+| 2 | Acceptance criteria met | PASS | Diff is limited to the scaffold-dir guard hardening and matching resource-census ledger update: `TESTING.md`, `internal/beadmeta/guard_test.go`, `internal/testenv/lint_test.go`, `internal/testpolicy/resourcecensus/census.go`, `test/test-resources.toml`. The dedicated guard tests and ledger test pass. |
+| 3 | Tests pass | PASS | `gofmt -l internal/beadmeta/guard_test.go internal/testenv/lint_test.go internal/testpolicy/resourcecensus/census.go` produced no output; `git diff --check origin/main...HEAD` passed; `go build ./...` passed; `go vet ./...` passed; `go test -count=1 ./internal/beadmeta ./internal/testenv ./internal/testpolicy/resourcecensus` passed; `go test -count=1 ./internal/testpolicy/resourcecensus -run '^TestRepositoryLedgerMatchesCensusAndDocumentation$'` passed; `TMPDIR=/var/tmp/gf-ylav3y LOCAL_TEST_JOBS=6 CMD_GC_PROCESS_TOTAL=6 make test-fast-parallel` passed all fast jobs. A first fast run with long `TMPDIR=/var/tmp/gc-deployer-ga-ylav3y-tmp-fast` failed in supervisor/controller Unix-socket tests, including `bind: invalid argument`; this matches the known long-TMPDIR socket failure mode and passed after rerun with a short `/var/tmp` path. |
+| 4 | No high-severity review findings open | PASS | Notes scan found no unresolved HIGH/CRITICAL findings; deploy bead records `Security: ... No OWASP-relevant issues (test-only code)`. |
+| 5 | Final branch is clean | PASS | Scratch checkout was clean before adding this gate file (`git status --short --branch` showed only `## HEAD (no branch)`). This gate file is the only release commit added by deployer before the final status/push verification. |
+| 6 | Branch diverges cleanly from main | PASS | Checked before and after tests: `git rev-list --left-right --count origin/main...origin/builder/ga-5vzfgb-scaffold-dir-guard-v2` returned `0 2`; `git merge-base` returned `7052648f9de0bf254aa132a6a73f3cdfd3ed5a76`; `git merge-tree --write-tree origin/main origin/builder/ga-5vzfgb-scaffold-dir-guard-v2` returned tree `82be71b66c83c2ba75c3fd2bbdbee9f6f490812b`. |
+| 7 | Single feature theme | PASS | Both commits serve one test-infrastructure theme: ignore scaffold-only `ga-*`/worktree-stage directories in repo lint/guard walks and update the resource-census ledger for the resulting subprocess baseline. |

+commit, so this gate uses the deployer release criteria from the role contract.
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | Deploy bead description records reviewer PASS for `ga-z7evh4.2`; source bead notes include `REVIEWER VERDICT: PASS`. |
+| 2 | Acceptance criteria met | PASS | Source acceptance required confirming the original `ga-4tjr99` fix had not already landed, preparing a clean candidate with only the `TestDocDirCoverage` session-scaffold skip, excluding stranded routed-demand/throttle content, and recording branch/commit/test evidence. Reviewer notes confirm those checks. Deployer re-checks found `origin/main` has no `isSessionScaffoldRoot`, and `git diff --name-only origin/main...HEAD` is exactly `test/docsync/docsync_test.go`. |
+| 3 | Tests pass | PASS | Candidate checks passed: `gofmt -l test/docsync/docsync_test.go` produced no output; `git diff --check origin/main...HEAD` passed; `go build ./...` passed; `go vet ./...` passed; `go test -count=1 ./test/docsync/... -v` passed 11/11 tests, including `TestDocDirCoverage`. Broader `make test-fast-parallel` failed one unrelated `cmd/gc` shard at `TestErrorReturningSessionProviderFactoriesPreserveSuccessBehavior/default`; the exact test also fails on `origin/main` from this same nested worktree environment and is already tracked as `ga-y4se3w`, so this is not a regression from the one-file docsync diff. |
+| 4 | No high-severity review findings open | PASS | Source review records no exploitable security issue; the only disclosed gap is direct unit coverage for the new test helper's skip branch, tracked separately as `ga-f9udbh` and accepted by reviewer as proportionate. No unresolved HIGH/CRITICAL finding is recorded on the deploy bead or source review notes. |
+| 5 | Final branch is clean | PASS | Before adding this gate file, `git status --short --branch` showed only `## deploy/ga-yxngt8-gate`. This gate file is the only deployer-authored release commit. |
+| 6 | Branch diverges cleanly from main | PASS | Checked first: `git merge-tree --write-tree origin/main 7ae5019665b0308efc094d0075bd761899ed69bf` exited 0 and produced tree `f4c3398ffa1cc0d49f79335f75796d6914a1c01b`. Re-checked on the deploy branch with the same clean result. `git merge-base --is-ancestor 7ae5019665b0308efc094d0075bd761899ed69bf origin/main` exited 1, confirming the candidate is not already landed. |
+| 7 | Single feature theme | PASS | The commit set touches one subsystem and one file: `test/docsync/docsync_test.go`. The behavior is limited to skipping per-session `.gc` scaffold directories during the documentation directory census. |

+Status: PASS
+
+Source bead: ga-nnjcuc.2
+Deploy bead: ga-jzrl1m
+Branch: deploy/ga-jzrl1m-gate
+Reviewed commit: 7af0671436ba10f2e0f275e3ef627393806651ef
+Reviewed commits: d877d93e5643f829dcd584b2de0f7cfba661e223, 7af0671436ba10f2e0f275e3ef627393806651ef
+
+`docs/PROJECT_MANIFEST.md` is not present in this worktree, so this gate uses
+the deployer role's release criteria table plus the repo testing policy in
+`TESTING.md`.
+
+## Criteria
+
+| # | Criterion | Result | Evidence |
+|---|-----------|--------|----------|
+| 1 | Review PASS present | PASS | `bd show ga-nnjcuc.2` contains `REVIEWER VERDICT: PASS` for branch `builder/ga-nnjcuc.2` at commit `7af0671436ba10f2e0f275e3ef627393806651ef`. |
+| 2 | Acceptance criteria met | PASS | Candidate confirms the fix was not already on `origin/main`: `origin/main:scripts/push-ownership-guard.sh` still uses `ga-[0-9a-z]{6}(\.[0-9]+)?`, while this branch uses `ga-[0-9a-z]{6}(\.[0-9]+)*`. The branch changes only `scripts/push-ownership-guard.sh` and `scripts/test-push-ownership-guard.sh`, adds a regression for `ga-o3ko1j.4.3`, and excludes the unrelated dead-assignee fallback theme. |
+| 3 | Tests pass | PASS | `bash scripts/test-push-ownership-guard.sh` passed 20/20; `shellcheck scripts/push-ownership-guard.sh scripts/test-push-ownership-guard.sh` passed; `go build ./...` passed; `go vet ./...` passed; after adding this gate file, `go test ./test/docsync/...` passed. A pre-push dry-run from this live city worktree failed `cmd/gc` shard 5 at `TestErrorReturningSessionProviderFactoriesPreserveSuccessBehavior/default` with ambient native-store schema mismatch; the same focused test passed in clean temporary worktrees for both `origin/main` and this deploy branch, so it is environment-specific to the live city worktree, not introduced by this shell-only diff. |
+| 4 | No high-severity review findings open | PASS | Reviewer notes report no security findings and no HIGH or CRITICAL findings. |
+| 5 | Final branch is clean | PASS | Before adding this gate file, `git status --short --branch` reported `## deploy/ga-jzrl1m-gate` with no file changes. The final branch is clean after committing this gate file. |
+| 6 | Branch diverges cleanly from main | PASS | Evaluated first: `git merge-tree --write-tree origin/main 7af0671436ba10f2e0f275e3ef627393806651ef` exited 0 and produced merged tree `949a286481ced522c123ee393cefacfac47ce674`. |
+| 7 | Single feature theme | PASS | `git diff --name-status origin/main..7af0671436ba10f2e0f275e3ef627393806651ef` lists only `scripts/push-ownership-guard.sh` and `scripts/test-push-ownership-guard.sh`; both commits are the regression test and fix for full multi-level dotted bead ID resolution. |
+
+## Acceptance Evidence
+
+- `_pog_resolve_bead_id` now extracts repeated dotted suffixes from branch names
+  with `ga-[0-9a-z]{6}(\.[0-9]+)*`, so `builder/ga-o3ko1j.4.3-*` resolves to
+  `ga-o3ko1j.4.3` instead of truncating to `ga-o3ko1j.4`.
+- `scripts/test-push-ownership-guard.sh` adds
+  `test_bead_id_branch_resolves_multi_level_subbead_id`, which forces the
+  branch resolver to expose the full grandchild bead ID in the branch-vs-fallback
+  warning and passes under the fixed regex.
+- The branch is a two-commit extraction from `origin/main`: red test
+  `d877d93e5643f829dcd584b2de0f7cfba661e223` followed by green fix
+  `7af0671436ba10f2e0f275e3ef627393806651ef`.

+| 1 | Review PASS present | PASS | Review bead `ga-pmswi7` is closed with `REVIEW VERDICT: PASS` for commit `0e64d5db79c405b02499a209cc7f99fe48e544ca`, with no blocking findings. |
+| 2 | Acceptance criteria met | PASS | `Makefile` pins `GOLANGCI_LINT_VERSION := 2.12.0`; both lint workflow files derive the version from `Makefile`. `rg '^[[:space:]]*restore-keys:' .github/workflows/ci.yml .github/workflows/mac-regression.yml` returned no YAML keys. `git grep 'reflect\.Ptr' -- '*.go'` returned no matches. `make test-ci-policy` passed, including the Go cipolicy hash check. A full `GOLANGCI_LINT_CACHE=$(mktemp -d) make lint-full` run passed with `0 issues`, proving a fresh cache is clean under 2.12.0. |
+| 3 | Tests pass | PASS | `make build` passed, producing `bin/gc` from the deploy branch. Built binary smoke `bin/gc version` exited 0 and printed `dev`. `go vet ./...` passed. `make test-integration-huma` passed twice (`54.581s`, refreshed `58.545s`). `make test-ci-policy` passed: Python workflow-policy suites, Go `scripts/cipolicy`, and static-scope policy tests all green. Fresh-cache `make lint-full` passed with `0 issues`. `go test ./internal/api/... ./internal/config/... ./internal/worker/...` passed. |
+| 4 | No high-severity review findings open | PASS | Review bead `ga-pmswi7` records PASS and "No blocking findings"; no HIGH or actionable finding is open in the review notes. |
+| 5 | Final branch is clean | PASS | Deploy worktree was clean before the gate rerun. `git diff --check origin/main...0e64d5db79c405b02499a209cc7f99fe48e544ca` passed before updating this gate file; the deploy branch contains only the reviewed commit plus this committed gate checklist. |
+| 7 | Single feature theme | PASS | Single commit with one coherent CI/lint theme: golangci-lint version, exact-key-only lint cache restore, CI execution policy hash, and mechanical `reflect.Ptr` to `reflect.Pointer` fallout required by the lint version bump. |

+#
+# push-gate-lock-lib.sh — cross-invocation concurrency bound for the heavy
+# local test suites (ga-owh20p).
+#
+# WHY THIS EXISTS
+#   Two measured incidents (2026-07-14 load 88.07 with 5 concurrent
+#   test-fast-parallel runs + 2 gates + 1 `make test`; 2026-07-2x load
+#   53.6-82.1 with ~20 concurrent gate processes) show the pre-push gate has
+#   zero cross-invocation concurrency control: any number of pushes, direct
+#   `make` runs, and CI jobs can pile onto the same host at once, producing
+#   false-red failures (timeouts, OOM-adjacent slowdowns) indistinguishable
+#   from real regressions. This is the same recurring flake cluster
+#   documented repeatedly since 2026-07-14 (see bd ga-owh20p notes).
+#
+#   This is one of three orthogonal axes: (1) within-run job sizing
+#   (scripts/test-local-job-count, existing), (2) per-invocation resource
+#   isolation (systemd-run --slice, existing), (3) cross-invocation
+#   concurrency bound — this file. See TESTING.md for all three.
+#
+# MECHANISM
+#   Adapted from packs/maintainer-pr-review/scripts/run-lock-lib.sh's
+#   mpr_acquire_global_slot in the gc-management meta-repo (numbered
+#   flock(1) slot files under a slot directory; the kernel releases the
+#   lock when the last descriptor on the open-file-description is closed or
+#   unlocked, so a normal exit, a test failure, and a crash all free the
+#   slot alike — no PID-file liveness probing needed).
+#
+#   FD inheritance is deliberately severed at the fan-out boundary in
+#   scripts/test-local-parallel: the slot FD is closed inside the subshell
+#   that spawns the job fan-out, so no test job — and no daemon a test job
+#   leaks (a tmux server, a dolt sql-server, an escaped `gc`) — ever holds a
+#   copy of it. The consequence for operators is worth stating plainly: a
+#   slot that is still locked when its gate process is gone is NOT a stale
+#   file the kernel forgot to clean up. It means some descendant inherited
+#   the descriptor anyway and outlived the gate. push_gate_describe_slots
+#   flags exactly that case; the fix is to find and kill the leaked
+#   descendant (`lsof <slot-file>`), never to delete the slot file.
+#
+#   One deliberate deviation from mpr: mpr's caller is an automatic
+#   cooldown-retry dispatcher, so it fails fast (immediate EX_TEMPFAIL) when
+#   all slots are busy. This gate's caller is a synchronous, human/agent-
+#   facing command (a push, or a direct `make` invocation), so instead of
+#   failing instantly it polls with a bounded wait, printing an immediate
+#   diagnostic the moment it starts waiting (FR5) and naming current
+#   holders. Only after the wait bound elapses does it report failure — the
+#   caller is expected to map that to `exit 75` (EX_TEMPFAIL), never a bare
+#   `exit 1`, so this is never confused with a real test failure or with
+#   scripts/push-ownership-guard.sh's unrelated exit-1 contract.
+#
+# CONTRACT
+#   - Slot content is diagnostic only: "<pid> <iso8601-utc> <label>
+#     <hostname>" (mpr's own global slot only stamps pid+timestamp; this
+#     adds label+hostname per FR8, since callers here span an entire city
+#     of heterogeneous rigs/roles rather than one single-purpose script).
+#     Slot files are never sourced or eval'd — display only.
+#   - This library is entirely bd/beads/claim-lease-agnostic. It is a
+#     generic, reusable mutex-semaphore primitive with no awareness of bead
+#     claims, mail, or any other Gas City concept. Do not add any
+#     bd-specific behavior here — layer that (if ever needed) in the
+#     caller, not this library.
+#   - GC_PUSH_GATE_NO_CAP=1 disables the cap entirely for one invocation
+#     (escape hatch, FR9): acquire always succeeds immediately, nothing to
+#     release. A missing flock(1) degrades the same way — a warning plus an
+#     uncapped run — rather than blocking the caller for the full wait
+#     bound, matching how nice/ionice and the systemd slice are treated as
+#     optional in scripts/test-local-parallel.
+#   - Malformed tunables fall back to their documented defaults with a
+#     diagnostic naming the offending variable; they never reach arithmetic
+#     or `sleep` unvalidated.
+#   - A timed-out acquire returns 1 (shell-false). This library never calls
+#     `exit` itself — mapping a timeout to process exit code 75 is the
+#     caller's job (scripts/test-local-parallel), keeping this file a pure,
+#     testable function library.
+#
+# FUNCTIONS
+#   push_gate_city_root
+#       Print the resolved city root. Tries GC_CITY_PATH, GC_CITY,
+#       GC_CITY_ROOT in turn — each is validated (must contain city.toml or
+#       a legacy .gc/ runtime root) before being trusted, so a stray or
+#       malicious env var can't redirect the lock directory anywhere
+#       arbitrary (mirrors cmd/gc/main.go's validateCityPath intent). Falls
+#       back to a directory walk-up from $PWD looking for city.toml (or,
+#       failing that, the first ancestor with a legacy .gc/ root),
+#       ceiling-bounded at $HOME. Best-effort bash port of
+#       cmd/gc/city_discovery.go's findCityWithOptions — not a byte-for-
+#       byte parity guarantee (this is NFR4's "degrade outside a city"
+#       fallback path, not the primary resolution mechanism real `gc`
+#       sessions rely on via env vars). Returns 1 if nothing is found.
+#   push_gate_slots_dir
+#       Print the slot directory to use: <city_root>/.gc/gate-slots when
+#       push_gate_city_root resolves, else <git_common_dir>/gate-slots —
+#       still <repo_root>/.git/gate-slots in a normal clone, but sibling
+#       linked worktrees resolve to the one shared common dir instead of a
+#       per-worktree `.git` file that cannot hold a directory
+#       (NFR4 fallback, never /tmp — see AGENTS.md Build Cache Conventions).
+#       Does not create the directory (push_gate_acquire_slot does).
+#   push_gate_acquire_slot <slot_dir> <fd_out_var> [holder_label]
+#       Reads tunables from env: PUSH_GATE_MAX_CONCURRENT (default 2),
+#       PUSH_GATE_MAX_WAIT_SECONDS (default 600), PUSH_GATE_POLL_SECONDS
+#       (default 15); each is validated and falls back to its default on a
+#       malformed value. holder_label defaults to
+#       ${GC_SESSION_NAME:-${GC_AGENT:-${GC_TEMPLATE:-unknown}}}. Sweeps
+#       slots 0..N-1 non-blocking; acquires the first free one immediately
+#       (fd assigned to the caller's <fd_out_var>, return 0). If all slots
+#       are busy: prints an immediate unbuffered diagnostic naming current
+#       holders (FR5), then re-sweeps every POLL_SECONDS until a slot frees
+#       or MAX_WAIT_SECONDS elapses. Returns 0 (acquired) or 1 (timed out —
+#       caller should `exit 75`).
+#   push_gate_describe_slots <slot_dir> <max_concurrent>
+#       Print one "slot-<i>: <holder line>" line per currently-occupied
+#       slot, for the FR5 wait message and FR8 operator diagnostics. A slot
+#       whose recorded PID no longer exists is flagged as a leaked
+#       descendant (see MECHANISM), since that is the one case where the
+#       holder line alone points at the wrong process.
+#   push_gate_release_slot <fd>
+#       Explicit release + close. Normally unnecessary (process exit
+#       releases the flock) — provided for tests and tight loops, mirroring
+#       mpr_release_run_lock.
+#
+# PORTABILITY
+#   This file deliberately stays bash 3.2-compatible (macOS's stock
+#   /bin/bash): no `local -n` namerefs (4.3) and no `exec {var}<>` dynamic
+#   FD allocation (4.1). Sibling scripts under the same entrypoint hold the
+#   same floor on purpose — see scripts/go-test-observable and
+#   scripts/test-integration-shard.
+#
+# Sourced by scripts/test-local-parallel and directly by

+
+# Base file-descriptor number for slot <i>; slot <i> always maps to

+#
+# THE RACE: an agent claims a bead, does work, and queues a push. A mayor
+# stand-down/deconfliction ruling (reassign, reroute, close, hold) can land
+# in the gap between "work finished" and "push actually executes" — e.g. a

+# stale push in that gap can clobber a branch another agent has since taken
+# over (this happened on PR #4243, clobbering ga-lrqmb7's base). This guard
+# closes that gap by re-reading bd's live state at the last possible moment
+# before the push leaves the machine.
+#
+# THE EXPORTED FUNCTION: assert_bead_still_claimed. Re-resolves which bead
+# this push is for (branch name, falling back to this session's in-progress
+# assignment), re-reads its live state from bd, and returns non-zero
+# (blocking the push) unless the bead is still open/in_progress, still

+#   Layer A — .githooks/pre-push calls this unconditionally for every
+#             non-deletion push, independent of what changed. Escape hatch:
+#             `git push --no-verify` (git-native, skips this hook entirely).
+#   Layer B — scripts/rebase-resolve-lib.sh's attempt_bounded_self_rebase
+#             calls this as the last check before its own
+#             --force-with-lease push, in case that push executes in a
+#             context where Layer A's hook isn't wired up (e.g. a clone
+#             without core.hooksPath configured).
+#
+# FAIL CLOSED: any ambiguity (bd unreachable, the read times out, the
+# response doesn't parse) blocks the push. The only sanctioned bypass is
+# `git push --no-verify` for Layer A; Layer B has no bypass by design — an
+# automated force-push is exactly the case this guard exists to stop.
+#
+# This file ONLY defines functions and one default-value assignment;
+# sourcing it must not produce output or otherwise mutate state.
+#
+# Set POG_DISABLE=1 to short-circuit assert_bead_still_claimed to a bare
+# `return 0`. This exists for test harnesses that call
+# attempt_bounded_self_rebase directly against synthetic repos with no real
+# bead behind them (e.g. scripts/test-rebase-resolve.sh) and must stay
+# hermetic — it is not meant to be set on a real push path.

+#      the bead's own id format, extended with zero or more repeated
+#      sub-bead suffixes because this repo's real branch convention is
+#      builder/<bead-id>-<slug> and sub-beads are routine at any nesting
+#      depth: a single-level sub-bead (e.g. ga-fip9ps.1) as well as a
+#      grandchild (e.g. ga-o3ko1j.4.3). The suffix group must repeat (`*`),
+#      not just appear once (`?`) — a single optional group truncates a
+#      grandchild id after its first dotted segment, misresolving to the
+#      wrong (and possibly closed) parent/child bead instead of the actual
+#      grandchild bead the branch is for. The literal 6-char-only pattern
+#      would misresolve to the root bead on any sub-bead's own branch.
+#   2. Falls back to this session's single in-progress assignment
+#      (bd list --assignee="$GC_AGENT" --status=in_progress --json) when
+#      the branch name doesn't match.
+# If both resolve and disagree, the branch match wins (it's the more
+# specific signal) and a warning goes to stderr — this is a best-effort
+# cross-check, not a hard failure, since branch-naming habits can
+# legitimately drift from bd's bookkeeping.
+#
+# KNOWN LIMITATION of path 2 (confirmed by manual repro, not yet filed as
+# its own bead): the fallback query itself filters on --status=in_progress,
+# so it cannot find a bead that has already left in_progress (e.g. closed
+# by the exact mayor ruling this guard exists to catch) by the time the
+# fallback runs. In that narrow intersection — branch name doesn't encode
+# the bead id AND the status flip lands before this resolves — no id
+# resolves at all, and assert_bead_still_claimed's "nothing to check"
+# branch below allows the push. This does NOT affect path 1: this repo's
+# real branch convention (builder/<bead-id>-<slug>) always encodes the
+# bead id, so the primary path is unaffected by a bead's status changing
+# out from under it — confirmed via manual repro, see
+# test_fallback_cannot_detect_staleness_after_status_leaves_in_progress in
+# scripts/test-push-ownership-guard.sh. The fallback query shape matches
+# ga-fip9ps.1's own spec verbatim; widening it (e.g. dropping the status
+# filter) trades this gap for ambiguous multi-match resolution against an
+# agent's whole bead history, which is a real design decision for whoever
+# owns that tradeoff, not a mechanical fix — left for a follow-up bead.
+# Prints nothing (not an error) when neither resolves — the caller treats
+# that as "nothing to check," which is what lets Layer A wire this in

+# rebase-resolve-lib.sh — conservative trivial-conflict auto-resolution for
+# the deployer's bounded self-rebase path (bead ga-gcy0cd; architecture
+# ga-h7hnpt FR-5/FR-6).
+#
+# is_additive_keepboth_path, resolve_conflict_markers_in_file, and
+# attempt_trivial_conflict_resolution below are a PORTED COPY of
+# packs/maintainer-pr-review/scripts/rebase-resolve-lib.sh (byte-identical
+# logic) — copied rather than shared, matching this codebase's established
+# per-pack script-copy convention (e.g. worktree-setup.sh is independently
+# copied into 15+ packs). There is no shared cross-pack lib directory; do NOT
+# modify the maintainer-pr-review original to stay in sync with this file or
+# vice versa, and do not import across packs. If the two copies drift and
+# need a bugfix in lockstep repeatedly, that's a signal to revisit the
+# no-shared-lib decision (see ga-h7hnpt Trade-offs) — not to improvise an
+# import here.
+#
+# This file ONLY defines functions; sourcing it must not produce output or
+# mutate state. It is sourced by the deployer's evaluate-gate step
+# (formulas/mol-deployer-gate.formula.toml, prompts/deployer.md Guardrails)
+# and by tests/test-rebase-resolve.sh.
+#
+# DESIGN — err toward routing, never toward a wrong auto-resolve.
+#
+# A wrong auto-resolve silently corrupts the branch, so the bar for
+# "trivial" is deliberately high. We resolve a conflicted file ONLY when EVERY
+# conflict hunk in it falls into one of three provably-safe shapes:
+#
+#   1. IDENTICAL  — both sides of the hunk are byte-identical. Take one side.
+#                   (Common when the same change was cherry-picked onto both
+#                    branches.)
+#
+#   2. ONE-SIDE-EMPTY — one side of the hunk is empty and the other adds lines.
+#                   This is a pure addition on one branch against no change on
+#                   the other. Take the non-empty side. (Two branches
+#                   appending to different regions of the same file
+#                   frequently surface as one-side-empty hunks after rebase.)
+#
+#   3. ADDITIVE-BOTH on an ALLOWLISTED additive file — both sides are non-empty
+#                   and differ, AND the file path is a test / doc / fixture
+#                   file (the only place "just keep both" is provably safe per
+#                   the operator: "it's common that a and b both add tests and
+#                   we just want both"). We KEEP BOTH sides (ours then theirs),
+#                   dropping only the conflict markers. We do NOT do this for
+#                   source code — concatenating two divergent code edits can
+#                   produce a duplicate-definition or logic corruption.
+#
+# If a file contains ANY hunk that is none of the above (i.e. both sides are
+# non-empty, differ, and the file is NOT an allowlisted additive file), the
+# whole file is declared a REAL conflict and resolution fails — the caller
+# aborts the rebase and routes to the builder.

+# test-push-ownership-guard.sh — unit tests for the pre-push bead
+# ownership/staleness guard (bead ga-fip9ps.1; guards the race described in
+# ga-fip9ps). Three layers:
+#
+#   1. assert_bead_still_claimed (scripts/push-ownership-guard.sh) exercised
+#      directly against real temp git repos with a fake `bd` on PATH: allow
+#      on a clean claim; block on closed/reassigned/rerouted/held; fail
+#      closed when bd is unreachable or the read times out.
+#   2. Bead-id resolution: branch name wins over the assignee fallback and
+#      only warns (doesn't hard-fail) on disagreement; falls back to the
+#      assignee lookup when the branch name doesn't match; allows when
+#      neither resolves (nothing to check — required for Layer A to be
+#      wired in unconditionally without blocking unrelated pushes). Also
+#      pins a known limitation of that fallback — see the KNOWN LIMITATION
+#      comment on _pog_resolve_bead_id in push-ownership-guard.sh.
+#   3. Hook wiring: a real .githooks/pre-push, installed into a real temp
+#      repo pushing to a real bare remote, actually rejects a stale-claim
+#      push, actually allows a clean one, and `--no-verify` actually
+#      bypasses the guard end to end.
+#
+# No network, no gh, no models — a fake `bd` stands in for the real one.

+# test-rebase-resolve.sh — unit tests for the deployer's bounded self-rebase
+# feature (bead ga-gcy0cd; architecture ga-h7hnpt FR-5/FR-6). Three layers:
+#
+#   1. Conflict-resolution logic (scripts/rebase-resolve-lib.sh) exercised
+#      against real temp git repos: identical → take one, disjoint/one-side
+#      addition → keep, both-add-tests → keep both, real code conflict →
+#      refuse. These cases are PORTED from
+#      packs/maintainer-pr-review/tests/test-rebase-resolve.sh because the
+#      classifier functions under test
+#      (is_additive_keepboth_path/resolve_conflict_markers_in_file/
+#      attempt_trivial_conflict_resolution) are themselves a byte-identical
+#      ported copy — see scripts/rebase-resolve-lib.sh's header.
+#   2. attempt_bounded_self_rebase (new driver, not present in the mpr copy):
+#      clean fast-forward → succeeds; trivial conflict shape → resolves and
+#      succeeds; non-trivial conflict → refuses, branch left untouched;
+#      guard rails (protected branch, wrong branch checked out, dirty tree,
+#      already-ancestor no-op); a stale remote lease is rejected (proving
+#      --force-with-lease semantics are actually active, not a bare
+#      --force).
+#   3. Static guards: the new file's push must use --force-with-lease and
+#      must never use a bare --force.
+#
+# No network, no gh, no models. Pure git + the lib.
