If one side runs on defaults, you compared configurations, not implementations. A limiter that is a setting, such as a commit per row, a debug build, or a missing index, means that side is untuned.

Narrowing the claim to the code as it ships today does not fix this when the user is choosing what to adopt, because they adopt the option, not today's settings. -3. **Did it break limits?** Do the arithmetic. Compare bytes per second with disk and network bandwidth, and operations per second times the cost per operation with the cores you have. Compare the time saved with the time the changed piece took. Removing a piece that takes 10% of the run can make the run at most about 11% faster.

Errors behave differently from successes. Rejections are often fast, and timeouts and retries are slow. If the script does not count errors, add the count. -5. **Does it reproduce?** Run each side at least 5 times, and alternate the sides (A, B, A, B, and so on) so that warmup, lazy initialization, caches, and drift do not favor one side.

Execution starts only on the operator's explicit go. -2. **Spawn one owner per PR with the full lifecycle and an early trail.** Every PR operation goes through `gh`. Never use Graphite (`gt`). One background `pstack:poteto-agent` per PR, spawned with `isolation: "worktree"` (`"remote"` when it must outlive this session), owns build, the first push, a draft PR, self-proof on the real artifact (**principle-prove-it-works**), skeptical review-bot triage per `../references/bugbot-triage.md`, a slop-strip with the built-in `/simplify` skill, `/no-comments` (the **no-comments** skill), the pre-PR gate (Opening a PR step 2), marking the PR ready, a rebase onto current trunk, the babysit loop to green (`playbooks/babysit.md`), and the merge itself. Within about 15 minutes, every owner starts a `decisions.tsv` trail per the **show-me-your-work** skill, pushes its first branch snapshot, and opens the PR as a draft. After that, the owner pushes its branch again after every verifiable unit (hooks on, a WIP commit is fine). Open the PR before self-proof so the URL, decisions, and checks form a durable trail. The owner marks it ready with `gh pr ready` only after self-proof passes and the interrogate gate is clean. Keep `decisions.tsv` uncommitted and return it with the reports. As soon as a subagent starts, the owner adds its ID, expected runtime (at least the longest past run of that kind), and state to a `children.tsv` kept the same way. The owner does the first rebase before the code-ready report and babysit, whether or not trunk has drifted. In fix rounds, the owner keeps that merge base. The owner rebases again only at merge prep (step 5), on a `git merge-tree` conflict with trunk, or on a CI failure that comes from a change on trunk. When the shipped code is final, after the slop-strip and `/no-comments`, it reports the code-ready head SHA. It also reports the SHA of each later push that changes the patch. Self-proof, CI, and babysit then run in parallel with the swarm. The owner reports merge-ready with the head SHA when self-proof, CI, and babysit finish. Before a push that starts a round, run the pre-review checks that the repo's CLAUDE.md and AGENTS.md files name for the touched paths. Run them on the committed head. A hook pass is not proof. To publish each rebase, push the owner's own branch with `git push --force-with-lease=<branch>:<sha it rebased from>`, so the push fails if the remote moved, or with `gh stack` for a private stack (step 3). Never force-push a shared branch. The merge is the one step an owner may not take alone. Step 4 gates it. -3. **Run owners in true parallel and never stack.** Many owners at once when PRs are self-contained: one writer per branch, disjoint files, cross-PR drift absorbed by rebase. Only genuinely overlapping work serializes. Self-contained PRs branch straight off main, and sequenced work is merge-then-branch. One exception: an owner that must split a genuinely dependent change may hold a short private `gh stack`. -4. **Swarm-verify every round before its merge.** A round starts at the owner's code-ready head SHA and at each later push that changes the PR's patch. At that SHA, fan out parallel independent verifiers per the **swarm** skill and aggregate to one verdict. The merge needs a clean verdict from the round whose patch matches the merge-ready head. Audit the receipts in the merge-ready report before the verdict. The lanes: re-run the gates at that SHA. Prove the load-bearing behavior live on the real surface the change touches (with the matching control skill, such as the `claude-in-chrome` browser tools or the built-in `run` skill, or a named driver where none exists). Audit the diff, distrusting the PR body. Run the audit as two or more review lanes with the full brief. Give each lane one main focus, such as consumer parity with trunk, lifetimes and races, or data and config safety. **Regression lane against trunk.** Run the same load-bearing scenario on current trunk. If trunk does not have the feature, record that fact and gate the behavior the diff adds plus the end state the user waits for instead of pretending trunk can produce it. The live lane is the floor, and a verdict without it is not clean. No merge without the root's clean verdict. When the lanes return, send every proven finding against the PR to the owner in one fix-forward. A defect that a lane filed as a note is a finding. For each behavior finding, ask for a red test that covers every site with the same defect. Where no test can show the defect, ask for a repro receipt instead. Add that defect to the next round's review brief. The new head gets a fresh swarm and a fresh verdict, except for lane results that stay valid under the patch-id rule in `playbooks/shipping.md`. -5. **On a clean verdict the owner merges, and a fresh owner takes the next item.** 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. Once that head is green and its patch-id matches the verdict's under the patch-id rule in `playbooks/shipping.md`, a later trunk move does not force another rebase. Right before the merge, fetch trunk and check that `git merge-tree` of the head against current trunk is clean. Also check that no path in `git diff --name-only $(git merge-base HEAD origin/main) origin/main` is a path the PR changes or a path that decides which CI runs for it, such as the repo's CI config paths. If either check fails, rebase again, report the new head SHA, wait for CI to pass on it, and repeat these checks. A new head voids the verdict unless the patch-id is unchanged. The owner merges its own PR with `scripts/merge-gate/merge-gate <pr> --merge`. A refusal is final, and the owner returns. A fresh owner picks up the next self-contained item from the queue, per poteto-mode's Subagents section. A `needs-human-approval` PR stops at merge-ready, like an operator-named item, and the report names its human-only files. The merge grant never covers it. The operator's full-autonomy grant plus the root's clean verdict is the merge authorization that babysitting alone never has. Operator-named items stop at merge-ready and wait for the operator's click. -6. **Run the root layer.** A genuinely new raise of a pinned gate or budget value (a limit CI only lets tighten) needs your fresh countersign, granted only after verifier proof. If the operator's grant or standing orders cover approvals, that countersign is the approval. The owner records it in the form that the tool's approval contract allows, with a pointer to the root's countersign. A lane checks the record against that countersign. The root never gives or bypasses an approval that the forge enforces. Absorbing values that already landed on main is drift, not a raise. Run an audit tick over all owners every hour. On the operator's go, arm `/loop 1h` with a prompt that runs this tick. Never leave the cadence to memory or lossy completion notifications. At each tick, re-read this playbook and audit the operation against it. Fix drift during that tick. Probe each owner with a generic liveness or status check, and collect the decision trails. Count only side effects as progress: commits, pushes, PR or check deltas, and store reports. Treat a lane that errors, or that passes its expected runtime without a side effect, as stuck. Stand it down and dispatch a replacement at once. Do not wait for a polite return. The tick judges an owner by the pushed branch and the decision trail that step 2 requires, and it replaces an owner whose agent cannot start a turn. Each tick also runs the lane stuck test over the program's agent list, where the platform has one, and over every owner's `children.tsv`. Whether or not a stop works, the root has the owner record each stuck subagent as stuck and, if its work is still needed, replace it. Each replacement that stalls gets the same steps. The root takes both steps when the owner cannot. A stall never proves or drops the work. When merges batch, run a retro pass and a post-merge bot-comment sweep. End the tick only when no delegated work is left, even after the last merge. -7. **Stand down instantly on the operator's stop.** The operator's hold or stand-down reaches every owner as a zero-writes order immediately. Owners hold their briefs until the operator releases them. +A verdict covers one patch and green CI covers one head. Step 4 runs a full swarm once, and again only for a major change. The patch-id rule in `playbooks/shipping.md` can carry a lane's result, and every new head needs its own green CI. -**Reply:** the queue with each PR's owner, state, and head SHA. Each verdict and the swarm that produced it. What merged and what each fresh owner took next. Countersigns granted and why. Open operator gates. Where the collected decision trails live. +1. **The operator's gates come first.** The grant covers only the queue's items, so items the operator names as theirs and PRs outside the queue stop at merge-ready. A request to state the plan is not a go. +2. **Spawn one owner per PR, and keep its work where a replacement can find it.** Every PR operation goes through `gh`. Never require Graphite (`gt`). Each owner is a background `pstack:poteto-agent` spawned with `isolation: "worktree"` (`"remote"` when it must outlive this session) that builds, opens its PR per `playbooks/opening-a-pr.md`, proves the change on the real artifact, babysits to green per `playbooks/babysit.md`, and merges once steps 4 and 5 clear it. + + Open the PR early so CI and bots run alongside the work. The code is ready only after the slop-strip (the built-in `/simplify` skill) and the `/no-comments` pass, so the full swarm runs on finished code. Then rebase onto current trunk and report the code-ready head before self-proof, so verification runs on the base the patch lands on. Report every later head, and merge-ready once self-proof, CI, and babysit are done. Fix rounds stay on that base unless trunk conflicts or breaks CI, because each rebase restarts CI. Run the checks that the repo's CLAUDE.md and AGENTS.md files name for the touched paths on the committed head before the code-ready push and before a later push that needs a verifier. + + Assume the owner dies. Soon after starting, push and start a decision trail per the **show-me-your-work** skill in the root's store (a path the root names in the brief), then push after every unit worth keeping. Whoever spawns a subagent records its id, state, and a stuck-after runtime from past runs of its kind in that store, so the root can probe it if the parent dies. Force-push only your own branch, with `--force-with-lease` pinned to the SHA you last pushed or took over, and on any push you did not make, stop and report to the root. +3. **Run owners in parallel off trunk, never stacked,** so each PR lands on its own. +4. **Swarm-verify once.** A full swarm runs once, at the code-ready head. Another full swarm runs only for new behavior, a redesign, or a large new diff. A rebase, a merge-conflict resolution, or a minor fix gets a single verifier at the new head. Fan out independent verifiers at the code-ready SHA per the **swarm** skill. They re-run the gates, prove the load-bearing behavior live on the real surface through its control skill (such as the `claude-in-chrome` browser tools or the built-in `run` skill) or a named driver, and audit the diff. The verdict is not clean without the live lane, or before you audit the merge-ready report's receipts, because no lane trusts a claim it has not checked. + + Send every proven finding, whatever a lane labeled it, to the owner in one fix-forward, with a red test across every site with the same defect. A defect trunk shows without the PR is recorded against trunk and does not gate the PR, but one the PR copies or newly reaches is the PR's own. Never push a fix yourself, because each branch has one writer. Replace a stuck owner instead. +5. **The owner merges only what you verified, tested on the trunk it lands on.** Green CI alone never authorizes a merge. Once the swarm's lanes have started, merge prep rebases onto current trunk, reports the new head, and waits for green CI. + + Right before merging, fetch trunk and ask whether its changes can affect the patch, because rebasing for every trunk move never ends. Rebase and wait for CI when the code that would land was never tested, as with a conflict, a file both sides changed, or a change to which checks run for the PR. A lockfile both sides changed needs no rebase when a frozen install passes on the merge result and the packages the PR changes resolve there as on the head, because that install tests the lockfile that would land, and a failing install means the rebase must repair it. When trunk changed a caller of the patch or something the patch depends on, such as code it calls or a dependency version, run the patch's checks on the merge result and merge on a pass. Otherwise merge. If trunk would force a third rebase past merge prep, hold and report to the root, which sequences the colliding work. + + The owner merges its own PR with `scripts/merge-gate/merge-gate <pr> --merge`. A refusal is final, and the owner returns. A `needs-human-approval` PR stops at merge-ready, like an operator-named item, and the report names its human-only files, because the merge grant never covers it. +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. Each tick re-reads this playbook from trunk and fixes drift, such as an unreported head or an unrecorded agent, by having its owner record it, because drift is a gap in the record, not a stall. It probes every agent, down to the leaf lanes, and judges each by its side effects, because status text and summaries can hide a stuck child. An agent is stuck when it errors, cannot start turns, or shows nothing new past its stuck-after runtime, and so is an owner that has neither pushed nor written a trail row by the first tick. One waiting on you or the operator is not stuck, so answer it. Replace a stuck agent at once, without waiting for its stop to land. A tick that changed something for the operator ends by catching them up per the **ketchup** skill, and one that changed nothing stays quiet. +7. **Stand down at once on the operator's stop.** A hold reaches every owner as a zero-writes order.

Never use Graphite (`gt`). One background `pstack:poteto-agent` per PR, spawned with `isolation: "worktree"` (`"remote"` when it must outlive this session), owns its change end to end: build, first push, a draft PR opened before self-proof, self-proof (gates, CI, receipts), skeptical review-bot triage per `../references/bugbot-triage.md`, a slop-strip with the built-in `/simplify` skill, `/no-comments` (the **no-comments** skill), the pre-PR gate (Opening a PR step 2), and babysit to green per `playbooks/babysit.md`. Owners parallelize when the work is self-contained. Within about 15 minutes, every owner starts a `decisions.tsv` trail per the **show-me-your-work** skill, pushes its first branch snapshot, and opens the PR as a draft. After that, the owner pushes its branch again after every verifiable unit (hooks on, a WIP commit is fine). The owner marks it ready with `gh pr ready` only after self-proof passes and the interrogate gate is clean. Keep the trail uncommitted and return it in the report. Owners also keep the `children.tsv` of Autopilot-full step 2. -2. **Audit on a real loop.** The root runs an audit tick every hour. On the operator's go, the root arms `/loop 1h` with a prompt that runs this tick, per Autopilot-full step 6. Never leave the cadence to memory or lossy completion notifications. At each tick, re-read this playbook and audit the operation against it. Fix drift during that tick. Probe each owner with a generic liveness or status check. Count only side effects as progress: commits, pushes, PR or check deltas, and store reports. Treat a lane that passes its expected runtime without a side effect as stuck. Stand it down and dispatch a replacement at once. Do not wait for a polite return. Probe all subagents and end the tick per Autopilot-full step 6. -3. **Hold the operator gates.** State-then-wait, so a request to state the plan is not a go. On the operator's stop, every owner takes an immediate zero-writes hold. -4. **Verify each round.** The owner reports its code-ready head SHA once the shipped code is final, and STACK-READY with the exact head SHA when its loop is green. The root verifies each round per Autopilot-full step 4, with STACK-READY in place of merge-ready. Nothing enters the stack unverified. -5. **Append on a clean verdict, never ship.** No owner merges, arms auto-merge, or closes. A clean verdict appends the PR to the one linear `gh stack`, in verified order or an order the operator specified. -6. **Single writer on topology, parallel writers on builds.** Owners push only their own branches and report the tip, current base, and intended parent. The root is the only topology writer. It keeps the chain in one `gh stack` checkout. To append a PR, run `gh stack link <stack-number> <owner-branch>`, which pushes the branch, reuses its open PR, and chains its base onto the stack's top. Then `gh stack sync` pulls it into the local stack, and `gh stack rebase` puts it on its parent's exact tip when it isn't already. Only the root PR targets trunk. Raw `git rebase` or force-push on a stacked branch breaks GitHub's stack tracking, so fall back to raw git only where `gh stack` has no equivalent. -7. **Absorb drift at the root, then re-verify what moved.** The root runs `gh stack sync` (or `gh stack rebase` when a conflict needs hands) to bring the chain onto current trunk from bottom to top. When a rebase surfaces conflicts in an owner's files, that owner fixes its own slice and the root pushes the result. A rebase rewrites every SHA above it and voids verdicts at the old SHAs. Apply the patch-id rule in `playbooks/shipping.md` at each verdict SHA. Anything that is no longer valid goes back through this playbook's step 4 before delivery. Re-run mergeability and CI after every rewritten push even when the patch-id is unchanged. The countersign rule is unchanged from Autopilot-full. A genuinely new pin raises a stop for the root's fresh countersign. Absorbing drift of landed values is not a raise. -8. **Deliver the chain.** The deliverable is one linear chain of verified PRs, reviewable bottom-up on GitHub, every link carrying its verifier verdict in the PR body or a comment. The operator reviews and lands it, with their own clicks, `gh stack merge`, or by arming merge-when-ready. +1. **Run Autopilot-full's owners, minus the landing.** Owners report STACK-READY in place of merge-ready. Once you link an owner's branch into the stack, the owner only adds commits and never force-pushes it, because a force-push on a stacked branch breaks GitHub's stack tracking. They never rebase onto another branch, trunk included, never run `gh stack`, 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. +2. **Give the topology one writer.** Owners push only their own branches and report each tip and its intended parent. Only you change the chain, because two writers on one chain undo each other. Keep it in one `gh stack` checkout. Append each clean PR in dependency order with `gh stack link <stack-number> <owner-branch>`, which pushes the branch, reuses its open PR, and chains its base onto the stack's top, then `gh stack sync`. Raw `git rebase` or force-push on a stacked branch breaks GitHub's stack tracking, so fall back to raw git only where `gh stack` has no equivalent. Never require `gt`. An owner takes your push as its new base and lease, and on a conflict resolves its own slice for you to push. +3. **Absorb drift at the root.** Until landing starts, apply Autopilot-full step 5's test to each link and bring the chain onto trunk bottom-up with `gh stack sync`, or `gh stack rebase` when a conflict needs hands, where the test calls for a rebase. Then apply the patch-id rule link by link, since a link's base is its parent. +4. **Deliver the chain, then keep your hands off it.** Each link carries its verdict in its PR. Once landing starts, nobody writes to the chain, because a second writer breaks a landing in flight. GitHub restacks the rest server-side as each bottom PR merges, per `playbooks/shipping.md`. 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.

Verify each PR independently, land only the verified run from the root, then keep your hands off the stack.** This is the half after `playbooks/babysit.md`. Run it only on an explicit request to land, merge, or ship. -1. **Verify every PR independently.** One background subagent per PR, not batched, each with `isolation: "worktree"`, each exercising the real surface with the matching control skill (such as the `claude-in-chrome` browser tools or the built-in `run` skill) against parent versus head. Each returns `PASS`, `PASS+NOTES` or `FAIL` and posts that verdict on its own PR. Safe means a verdict from an agent that did not write the code. CI green is not a verdict, and an approving bot review is not a verdict. -2. **Land only the contiguous verified run rooted at the bottom.** Walk up from the lowest unmerged PR and stop at the first one without a passing verdict, where both `PASS` and `PASS+NOTES` pass. A verified PR sitting above an unverified one is not landable. Report the ceiling as a PR number and say what breaks the chain. -3. **Re-check that each verdict still describes the patch.** Record the verdict head SHA, base SHA, and stable `git patch-id` of that PR's base-to-head diff. A rebase or base retarget rewrites SHAs and can silently invalidate a verdict without touching a check. Before landing a PR, compare the recorded patch-id with its current base-to-head patch-id. When the two patches differ only in tests, docs, or lint config, build what each lane ran. Build it twice at the verdict SHA and once at the current head. A difference is noise if the two builds at the verdict SHA also show it, or if it is an embedded commit SHA. Judge each difference, not each file, and report each kind of noise with its files. If only noise differs, that lane's result stays valid, and checks and a review of the change run fresh. Do not reuse a lane result from a dev server or from anything else with no build output. Rerun that lane. Re-verify anything else when the patch changed. When it did not, keep the code verdict but re-run mergeability and CI at the current head. Never use matching commit messages or a green check from an older SHA as a substitute. -4. **Prepare only the bottom PR.** Fetch current trunk. Bring the lowest verified branch onto the exact trunk tip when needed, with `gh stack rebase --downstack` from the bottom branch and `gh stack push` for a `gh stack`, or a rebase and push otherwise, and retarget only that PR to trunk with `gh pr edit <pr> --base <trunk>` if GitHub has not. Re-run step 3 after the push. Do not retarget, arm, or merge descendants yet. -5. **Land one PR at a time.** Once the bottom PR is green, merge it with `scripts/merge-gate/merge-gate <pr> --merge`. A refusal stops the landing. For `needs-human-approval`, report the PR and the human-only files the gate listed, and leave the merge to the user. Never arm `--auto`: without required checks, GitHub merges it at once. Wait for that PR to merge before preparing the next one. -6. **Do not read GitHub `autoMergeRequest` as stack readiness.** At most it says GitHub auto-merge was requested for one PR. It does not prove that a descendant is queued, that a patch verdict is current, or that the contiguous stack is safe. Confirm GitHub's state for the current bottom PR, and say that the state is unknown if GitHub cannot report it. -7. **Recompute after every merge.** Fetch trunk, confirm the merged SHA is present, drop the merged PR from the frozen bottom-to-top list, and inspect the new bottom PR's base, head, checks, and patch-id. A host may retarget a child automatically, but do not assume it did. Repeat steps 3 through 6 for that one PR. Independent work stays outside this chain and ships on its own. -8. **Watch the current frontier until it merges or fails. Do not mutate the queue around it.** Use `scripts/watch-pr/watch-pr --queued-stack --stack-prs <bottom>` only as an event wake and poll `gh pr view <pr> --json state,mergedAt,mergeStateStatus,statusCheckRollup,autoMergeRequest` after each wake, ignoring `READY` until `mergedAt` is non-null or `state` is `MERGED`. Only then run step 7. Hard-fail only when `state` is `CLOSED` with no `mergedAt`, a required check concludes `FAILURE` or `CANCELLED` and blocks merge after auto-merge is no longer pending, or `mergeStateStatus` is `UNSTABLE` or `DIRTY` with no auto-merge pending. `BLOCKED` while checks are pending or auto-merge is armed is not failure. Do not use Babysit's queued `WAITING`/`merge-queue` stop condition here. Hold the watch under `/loop` in dynamic mode. Report each merge and the new ceiling. If the queue stalls, diagnose before mutating. -9. **Stop at the ceiling.** When the verified run is merged, report what landed, what the next unverified PR is, and what verifying it would take. Extending the run is a new pass through step 1. +1. **Verify each PR independently before it lands.** Every PR operation goes through `gh`. Never require Graphite (`gt`). One verifier per PR, each a background subagent with `isolation: "worktree"`, runs the change the way a user would with the matching control skill (such as the `claude-in-chrome` browser tools or the built-in `run` skill), parent against head, and posts `PASS`, `PASS+NOTES`, or `FAIL` on that PR. Only a verdict from an agent that did not write the code counts, because an author checks what it meant to build. Green CI and an approving bot review are not verdicts, because neither runs the change as a user would. +2. **Land only the contiguous verified run rooted at the bottom.** Walk up from the lowest unmerged PR and stop at the first one without `PASS` or `PASS+NOTES`. The PRs below it are the run, and the top one is the ceiling. A verified PR above an unverified one waits, because it cannot land without the code below it. Moving one out of a `gh stack` takes the interactive `gh stack modify`, so leave that to the user. Once its branch neither holds nor needs that code and it targets trunk, it can land on its own after a fresh verdict, because its old one ran with that code beneath it and trunk does not have it. +3. **Re-check that the verdicts still describe the code.** A verdict covers a patch, and a chain rebase moves every PR above it to a new SHA without failing any check. Compare `git patch-id` at the verdict SHA with the current head before trusting an older verdict. When the patches differ only in tests, docs, or lint config, a lane's result stands if what it ran builds the same at both SHAs apart from noise. Noise is a difference that also shows up between two builds of the verdict SHA, or an embedded commit SHA. Report each kind of noise with its files, so a reader can check the call. The change itself still gets fresh checks and a review, because the old verdict never saw it. A lane with no build output, such as a dev server, cannot show this, so rerun it, and re-verify anything else that drifted. +4. **Land bottom-up, one PR at a time.** Always merge the run's lowest unmerged PR. Bring its branch onto the exact trunk tip when needed, with `gh stack rebase --downstack` and `gh stack push` from the bottom branch, and re-run step 3 after the push. Merge with `scripts/merge-gate/merge-gate <pr> --merge`, which refuses a PR whose base is not trunk, because one whose base is still its parent's branch would merge into that branch. A refusal stops the landing. For `needs-human-approval`, report the PR and the human-only files the gate listed, and leave the merge to the user. Read the PR back (`gh pr view <pr> --json state,mergedAt,baseRefName`), because a merge can report success when a merge queue only queued the PR. A landed PR reads merged with trunk as its base. Never arm `--auto`, because without required checks GitHub merges it at once. After a merge lands, GitHub restacks the rest of a `gh stack` server-side. Run `gh stack sync`, confirm the next PR now targets trunk, and let step 3's patch-id rule decide whether its verdict survives. Merge it once its checks pass and its verdict survives. +5. **Leave the stack alone while it lands.** Step 4's rebase, push, and sync are the only changes to a branch or base, because a merge lands whatever its branch and base hold at that moment, verdict or not. Use `scripts/watch-pr/watch-pr --queued-stack --stack-prs <bottom>` only as an event wake under `/loop` in dynamic mode, and after each wake read `gh pr view <pr> --json state,mergedAt,mergeStateStatus,statusCheckRollup` for the current PR until `mergedAt` is set. A base that moves to trunk when its parent merges is expected, not damage to repair.
