Twenty-three upstream commits since 0.15.29 touch pstack. Eighteen change skill content or scripts. Seventeen of those are applied with the port adaptations below, and the deletion of `scripts/orch/` supersedes `3c596e7`'s `orch` fix. Four bump only the Cursor manifests. `a0b0ad9` changes only the upstream README. Default roles and panels are unchanged. + +**New skills.** `/statechart` checks a TLA+ model of a system that moves between states and draws it as a Mermaid statechart, with the shortest path to each state that breaks a rule. Its first run installs TLC and Java with mise and needs the network. `/ketchup-video` catches you up like `/ketchup`, as a short subtitled video of slides with the waiting calls as text under it. Both run only when typed. `/create-formal-verification-skill` tells the skill it generates to read each TLA+ result with `statechart`. + +**Interrogate proves findings by running them.** Adversaries try to break the change, and a finding survives only when a run proves it. Each adversary runs as an `isolated-write` lane in its own worktree, which the parent prepares at the reviewed HEAD with the uncommitted changes copied in. A configured provider without an `isolated-write` route, such as the read-only providers, is a named dropout. The report lists the intent, each adversary or its dropout, the verified findings with their commands and output, and the dropped count per adversary. When no adversary completes, it says the coverage is incomplete. + +**Orchestrate is agentic.** The coordinator runs the program with its own tools: workers through provider dispatch in dedicated worktrees, state in `/orchestrate//notes.md`, and `watch-pr` waits. `scripts/orch/` is deleted. A worker is replaced only on affirmative failure evidence, and a tool error or an unavailable model is a named dropout, never a retry on another model. + +**Autopilot-stack is Autopilot-full without the merge.** It stops when each PR is verified and green, hands the PRs to the operator, and pushes nothing after the handoff without the operator's go. A PR stacks only on a PR it builds on, and each owner restacks its own branch through Autopilot-full step 2, which now holds the fork and split-remote rules. + +**Changed behavior.** Poteto-mode restates the user's goal in its first message, in each subagent brief, in each PR's `## Why`, and in each final report, and applies Explain the Number before measuring. The arena judge is never from the parent's provider; when no configured judge runs, Arena skips the judge and says so. Reflect never edits a skill in the plugin cache and copies it to the harness's project or user skill folder first. Autopilot-full and the multi-phase plan block a PR only for a problem a run or a wrong doc line shows, rebase when a known concurrent change to the same files lands, and push each finished unit. `watch-pr` ignores fork heads when it discovers a stack and caps each sleep at an explicitly set deadline. `check-plan` ignores punctuation inside multi-backtick code spans. `worktree-audit.sh` works with GNU `stat` and `date`. + +**Install note.** Claude Code leaves auto-update off for third-party marketplaces.

The owner merges only from a head freshly rebased onto trunk. Merge prep never comes before a round's lanes start, and it ends with a rebase onto current trunk right before the merge. After the merge-prep rebase, the owner reports the new head SHA. CI must pass on that head before the merge, and the patch-id rule decides whether the round's verdict still holds. The merge-ready report records the verdict SHA and the current landing SHA. If trunk moves again before the merge, the patch ID rule in `playbooks/shipping.md` governs re-verification. A changed patch needs a new verdict. An unchanged patch keeps the verdict, but Shipping step 3 records the new `<landing-sha>` after current CI and mergeability pass. The owner lands its own PR only through Shipping step 5's server-enforced expected-head flow bound to `<landing-sha>`; never use a PR-number-only merge or unguarded auto-merge. The owner then returns. A fresh owner picks up the next self-contained item from the queue, per poteto-mode's Subagents section. The operator's full-autonomy grant plus the root's clean verdict is the merge authorization that babysitting alone never has. 6. **Run the root layer.** Anything that loosens a gate, such as a raised budget or an allowlist entry, needs a verifier's proof and then your fresh countersign, because the owner is the one who wants green. Under a grant that covers approvals, that countersign is the approval, and the owner's record of it points at your countersign for a lane to check. A disabled or soft-failed check always comes out, because it stops guarding every case. Never give or bypass an approval the forge enforces, because no countersign covers it. On the operator's go, arm `/loop 1h` to audit until no delegated work is left, because long runs drift and agents stall silently. The tick is an observation cadence, never a lease, deadline, or cancellation threshold. Each tick re-reads this playbook from disk (`skills/poteto-mode/playbooks/autopilot-full.md` under the installed plugin) and fixes drift, such as an unreported head, an unrecorded agent, or an owner that has neither pushed nor written a trail row, by having its owner record it, because drift is a gap in the record, not a stall. It probes every agent through its retained handle, down to the leaf lanes in each `children.tsv`, and judges each by its side effects, because status text and summaries can hide a stuck child. An agent is stuck only on affirmative failure evidence: it errors, its process is dead, its handle fails, it cannot start turns, or a caller-supplied external deadline passed. Elapsed time or the absence of a new side effect alone never proves it stuck; implementation runs can stay healthy for 90 minutes or much longer. One waiting on you or the operator is not stuck, so answer it. Cancel a stuck agent through its retained handle and replace it at once, without waiting for its stop to land.

Owners report STACK-READY with the exact head SHA in place of merge-ready. They never rebase onto another branch, trunk included, and never retarget, merge, close a PR, or arm auto-merge, because the root owns the chain's topology and the operator owns the landing. When an item depends on another, its owner branches from that item's branch, not from trunk. Nothing enters the stack before a clean verdict from Autopilot-full step 4. -2. **Give the topology one writer.** Owners push only their own branches and report each tip, its current patch base, and its intended parent. Only you rebase or retarget a link, because two writers on one chain undo each other. Append each clean PR to one frozen bottom-to-top list in dependency order, or an order the operator specified. For same-repository heads, the forge's base-branch chain also records that order. For fork heads, every PR targets trunk, so never infer stack order from their equal base branches. Never require Graphite (`gt`). An owner takes your push as its new base and lease, and on a conflict resolves its own slice for you to push. +1. **In place of step 5, stop at verified.** Stop when each PR is verified and green at its current head, then hand the PRs to the operator. After the handoff, nobody pushes without the operator's go. Every loop tick prompt names this file (`skills/poteto-mode/playbooks/autopilot-stack.md` under the installed plugin), so each tick sees the no-merge rule. +2. **Stack a PR only when it builds on another PR.** This is the one exception to step 3. Base the PR on the other PR's branch in place of trunk, per **Size and stacks** in `playbooks/opening-a-pr.md`. Each owner restacks its own branch through the stacked-owner rule in Autopilot-full step 2, with the same disarm-and-confirm rule and captured-SHA lease. - Before you rebase, force-push, or retarget an existing PR, apply Shipping step 4's disarm-and-confirm rule to that PR and every descendant, stopping if the forge cannot confirm every request off. Fetch trunk through `<base-remote>`. Fetch another stack branch directly through `<head-url>`, because `<head-remote>` may have the base repository as its fetch URL and the fork as its push URL. Validate the chosen repository identity through the active forge, and record the fetched target as `<parent-tip>`. Before rebasing, record the child branch's published SHA as `<captured-sha>` with `git ls-remote -- "$head_url" "refs/heads/$branch"` and require it to equal the local pre-rebase tip. Require `git merge-base --is-ancestor "$current_base_sha" "refs/heads/$branch"` to pass. When the parent changed, move only the child's commits with `git rebase --onto "$parent_tip" "$current_base_sha" -- "$branch"`, then record `<parent-tip>` as the child's new patch base. Publish with `git push --force-with-lease="refs/heads/$branch:$captured_sha" -- "$head_url" "HEAD:refs/heads/$branch"`. When the head and base repositories are the same, create or retarget the child PR with the parent branch as its base. Use `origin pr create --status open --base "$parent_branch"`, `gh pr create --base "$parent_branch" --repo "$base_repo"`, `origin pr edit "$pr" --base "$parent_branch"`, or `gh pr edit "$pr" --base "$parent_branch" --repo "$base_repo"` according to the resolved forge and operation. When the head repository is a fork, keep the local child branch rebased onto its parent's exact tip but create or retarget every PR against `<trunk>` in the base repository. With GitHub, capture the approved PR title and body as `<title>` and `<body>`, then create it with `gh api --method POST "repos/$base_repo/pulls" -f "title=$title" -f "body=$body" -f "head=$fork_owner:$branch" -f "head_repo=$head_name" -f "base=$trunk" --jq .html_url`; add `-F draft=true` only when Opening a PR's readiness rule requires a draft. Otherwise use the resolved Origin equivalent. Retarget it with `gh pr edit "$pr" --base "$trunk" --repo "$base_repo"` or the resolved Origin equivalent. A forge cannot use a fork-only parent branch as a PR base. -3. **Absorb drift at the root.** Until landing starts, fetch current trunk through `<base-remote>` and rebase the chain bottom-up with step 2's explicit old-base and new-parent flow. When a rebase surfaces conflicts in an owner's files, that owner fixes its own slice and you push the result using step 2's captured-SHA lease flow. A rebase rewrites every SHA above it, so apply the patch-id rule in `playbooks/shipping.md` step 3 link by link, since a link's base is its parent, using each PR's recorded patch-base-to-head diff. Anything no longer valid goes back through Autopilot-full step 4 before delivery. Re-run mergeability and CI after every rewritten push even when the patch ID is unchanged. -4. **Deliver the chain, then keep your hands off it.** The deliverable is the frozen bottom-to-top list, reviewable in the resolved forge, and each link carries its verdict in its PR. Same-repository heads use a base-branch chain. Fork heads retain local parent ancestry while every PR targets trunk. The operator sends only the current bottom PR through Shipping, one at a time. A merge-when-ready request applies only to that bottom after Shipping has disarmed and confirmed every descendant; never offer or arm merge-when-ready for the chain as a whole or for a descendant. Once landing starts, nobody writes to the chain except the post-merge move that Shipping step 4 sanctions, because a second writer breaks a landing in flight. A mid-landing problem goes through you to the operator, and any fix waits for the operator's go. - -**Choosing between the autopilots.** Autopilot-full when the PRs are independent and landing authority is granted.

Verbatim paste is for every resume and for any brief that has to stand alone. - -A sub-coordinator brief adds its track boundary and unit list, its spawn budget, the drain protocol, and the rollup format (per child: name, status, PR, head SHA, verdict, one line, plus track status and frontier delta). - -A dependency is a context relay, not just ordering. Undeclared upstream context makes the worker guess. Missing fields are a refuse-to-spawn condition. Audit one sampled worker brief per sub-coordinator per wave, concurrently with the wave it samples, never as a gate in front of it. A failing brief stops that track and fixes the sub-coordinator's instructions, not just the worker, because brief quality decays late in a run. Never resume-chain a brief. Respawn fresh with consolidated scope. - -#### Steps - -1. **Frame.** State the done predicate as something countable ("all 126 units merged, each ledger-verified `unit-test-verified` or better"). Quantify scope: units, rough effort, expected stacks, and the wall-clock budget. If one agent could finish inside that budget, stop here and run Autonomous run instead. Collapsing must not depend on another document being present. It means do the work directly in this session, plain workers where they help, verification inline, landing as you go, and none of the store, register, or pilot machinery below. Schedule landing against the budget. By roughly 70% of it, stop spawning and land what is verified. Name the tracks per project. A contested decomposition or one-way door goes through the arena skill before the pilot. Present the framing once. Reversible prep proceeds without waiting. -2. **Install the runtime.** Run `orch init`. Open the trail via the show-me-your-work skill, write the standing orders before any spawn, and seed `frontier.json` from existing PRs with `orch frontier set --repo <repo-dir>`, adding `--forge origin` when the forge is Origin. -3. **Pilot.** Push one unit through the whole path: brief, worker, verification, stack entry, ledger row, merge. The pilot exists to falsify the brief template, the verify recipe, and the unit size while that costs one agent instead of fifty. Fix the contract from pilot evidence before any fan-out. Scale the pilot to the unit. On programs of near-identical cheap units, the first unit is the pilot, run as a normal unit with its verify command inline, and fan-out starts the moment it lands. The dedicated pilot pipeline (separate verifier agent, audit gate) is for expensive or novel unit shapes, not for clone-units where a serialized pilot has nothing to falsify. -4. **Scale.** Spawn a rolling window of workers up to the in-flight cap, refilling as children finish. Blocking batches pay the slowest child of every batch. Spawn track sub-coordinators only past the one-drain threshold in Roles. Recompute ready work after each drain. Relay upstream reports into downstream briefs. Keep sibling communication upward only. The sampled brief audit runs alongside the wave it samples and stops the next refill on failure, not the current one. -5. **Drain.** Run the queue discipline below at every drain point. -6. **Land.** Landing is continuous, never a terminal phase. Integration starts with the first verified unit and runs alongside the remaining waves. On heavy repos the stacker is a standing role from wave one, integrating as units verify. On repos where local git is cheap, the coordinator lands verified units itself per Roles. Keep the frontier green before upper-stack work. Stack safety governs. Advance `frontier.json` only on merge or reported new head SHAs. -7. **Close.** Drain the final inbox, reconcile every spawned agent to a terminal row (done, abandoned, zombie-reconciled), confirm the predicate on the real artifact, confirm every landed PR has a verdict for its current head SHA, audit the trail per show-me-your-work including its cross-model review, encode recurring corrections into `preferences.md` or the brief template. Leave the store intact. It is the postmortem. - -#### Queue and drain - -- On a completion notification, run `orch inbox push <agent> <unit> <status> [--report PATH]` and return to what you were doing. Never deep-review inline. A completion that needs review becomes a verifier unit. Never review a diff inside a drain. -- Drain in batches at four points: the end of a critical section, a track rollup, a frontier watcher wake (arm it via the loop skill, with a long heartbeat fallback), and before a human report. Begin each batch with `orch inbox drain`. Arrivals during a drain wait for the next one. -- Critical sections you finish first: authoring a brief, a stack operation, a conflict decision, writing a gate, updating ledger or frontier. -- Each drain classifies every pointer (landed, needs-verify, failed, zombie, noise), writes the resulting rows through `orch unit add`, `orch unit set`, and `orch ledger record`, runs `orch status`, then spawns the next wave in one message. -- Account for every spawned child at its track's rollup: arrived, respawned, or its scope explicitly absorbed. Silently redoing a missing child's work hides both the wasted spend and the coverage gap its result existed to close. -- A drain turn ends with the three lines from `orch status`: counts against the states, what changed, gates open. Detail lives in `status.md`. The full reply contract applies at checkpoints and close. - -#### Stack safety - -- The frontier is a computed object, never narrative. Recompute `frontier.json` after every merge and stack mutation: ordered PR list, branch names, head SHAs, a generation number, the lowest unmerged PR. The command walks the PR base chain through the checkout's current branch, so chain order and PR states come from the forge. It uses `gh` by default. Pass `--forge origin` when the program resolved the forge to Origin. Head SHAs come from local branch refs, so resolve it from the stacker's clone. A branch with no PR errors rather than guessing. -- Exactly one stacker per stack may mutate topology (chain rebases, force-pushes, base retargets, merges), serialized within its stack. Record the holder in the standing orders. A chain rebase at this scale is slow and blocks whoever runs it, so give it its own unit and keep the coordinator out of it. -- Workers never rebase and never retarget or merge PRs. Babysitters follow `playbooks/babysit.md`, one per stack, scoped to one immutable frontier generation. They report conflicts to the stacker rather than rebasing. -- PR closes and retargets go through the stacker only. Closing a base PR orphans every chain above it. Merges and stack surgery are units with briefs like any other. -- One retro watcher follows merged PRs for reverts, post-merge CI breaks, and orphaned follow-ups. - -#### Verification - -Scale verification to the unit. When VERIFY is a single cheap command, the worker runs it and reports the output, and the coordinator spot-checks receipts. A dedicated verifier agent (on a different model family than the worker) is for units whose verification is expensive, judgment-laden, or high-blast-radius. A verifier agent whose entire product would be rerunning one command is ceremony, not verification. - -Write ledger rows with `orch ledger record`. Check the current PR and head SHA with `orch ledger check`. `ledger.tsv`, one row per verdict, keyed by PR number plus head SHA: `live-ui-verified | unit-test-verified | type-check-only | verifier-blocked | verifier-failed`. CI green is an input to a verdict, not a verdict. Behavioral work needs better than `type-check-only`. `verifier-blocked` is not a pass. Respawn when the environment heals. `verifier-failed` gets a fix unit, not a re-verify. A worker may self-report. A verifier overrides it on the same key. A new head SHA voids the row, so re-verify after restack. The ledger answers "was this verified", not memory and not the transcript. - -A unit is not done until its output is externalized the moment it lands, never batched to the end of the run. A worker pushes its branch, a verifier writes its ledger row, receipts land in the store. Work that exists only on one VM when that VM dies was never done. - -#### Liveness and failure - -- Never resume an agent to check on it. A resume restarts an idle agent. Probe read-only: the ledger, `units.tsv`, `gh`, pushed branches, and the background task list. Transcript mtime is not liveness. -- A silent death gets a synthetic postmortem row in the inbox (unit, failure mode, last evidence, options). Replan on evidence as it arrives. Never wait for full quiescence. -- Retry by mode: cap-hit or oom, respawn with smaller scope. Network-drop, retry as-is. Tool-error, retry on a different model. Unknown, retry once. Two retries, then abandon the unit and replan around it. -- A zombie that returns hours late reconciles against the current frontier and ledger before anything is accepted. Salvage unique findings through a fresh unit, never a blind merge. -- When continued spawning would produce garbage tree-wide (bad upstream output, broken acceptance, dead infra), write a stop line at the top of the standing orders, let in-flight work finish, fix the cause, clear it. -- Bound your own infra retries the same way you bound a child's. After a few consecutive tool aborts, stop retrying. Write a terminal handoff to durable state (what is done, where it lives, the exact command to resume) and end the run. -- After a session restart: in-flight subagents are dead; pushed branches, open PRs, and the store are not. Re-read the standing orders and `units.tsv`, recompute the frontier, reattach in-flight work by PR and branch rather than agent id, respawn one sub-coordinator per track from its stored brief plus current state, drain, resume. The dead session's store lock clears itself on the next write. `orch` replaces a lock whose holder pid is gone. - -#### Escalation - -Reaches the human, batched into the status page rather than per item: irreversible actions (force-push to shared branches, deploys, deletions, closing someone else's PR), genuine product or preference calls no experiment settles, a standing order that contradicts observed reality, a program-level dead end that survived a replan. Park each as a `gates.md` entry before asking, and route work around it. - -Never reaches the human: frontier nudges, rebase mechanics, retries, CI flake triage, review-thread triage, format fixes, scope the brief already forbids (refuse and continue), and "should I keep going". When in doubt, act and log. - -Mid-run discoveries fix only what blocks the frontier. Everything else parks in follow-ups. At this fan-out a small scope leak multiplies into PRs nobody asked for. - -**Reply:** at checkpoints and close: the predicate and the count against it from `units.tsv` and `ledger.tsv`, tracks and what each landed, the frontier (PR list plus SHAs), verdicts summary, what was abandoned and why, gates awaiting the human (the only asks), the store path, and the trail path.

In a regions chart, the command writes the condition on the other regions on the arrow, in the words of their labels, such as `[when Offline]`. Your brackets replace it, and two arrows from one state can then look the same. So in a regions chart, do not write brackets for a condition on another region.

Keep the constants small, or add a CONSTRAINT. +- With a VIEW or a SYMMETRY, TLC counts states that it treats as the same as one state, and the chart draws that one state.

When TLC's shortest path for a rule ends in such a state, the chart draws that state, and the report gives that path. The chart does not draw the other states past the bound. A deadlock in such a state does not show. TLC also checks the rules after each step that an ACTION_CONSTRAINT excludes, also when it reaches the next state another way. When TLC's shortest path for a rule ends with such a step, the chart draws that step. +- The command checks the rules with TLC on the config as written, with one worker. When a rule breaks, the command removes that rule and runs TLC again, until no rule breaks. After the first break, each run stops at 100,000 distinct states, so that a large model does not run without end. When a run reaches that bound or stops on an error, the report lists the rules that it did not check under "Rules not checked", and the chart does not mark them. A rule that is not checked can hold or break. To check it, remove the rules that break from the config, or make the model smaller. The bound adds a module that changes TLC's order of the variables, so for a property TLC can find a different counterexample than a run without the bound. +- `tlc.out` is what TLC printed on the config as written. When the chart does not show the bug path of a rule that breaks, `tlc-RULE.out` is what TLC printed for the run that found it. When TLC repeats its first warning, plain TLC prints it twice, but `tlc.out` shows it once, because TLC leaves the second copy out of the output that this command reads.
