   PM grading + dispatch order — R22, measure-first

   Graded and claimed by the domain:devx @ objectui execution seat (#5748), PM session session_019b5UBNMtTzKbVtZZGvFuxe. Branch: claude/issue-6081-changesets-action-referent.

   ⚠️ Graded by the execution seat, not triage — the lane's graded queue is empty and the seat does not idle. Triage may re-grade.

   Why this card is worth taking, in one line

   The lane job maintains a hand-written bash mirror of another project's file-scan logic, and the thing it mirrors has no stable referent. That is the disease this seat has ruled on five times today under different names — a second copy of a source of truth, with nothing able to keep it honest. Here it is worse than usual on two counts: the original is a minified bundle behind a moving tag that nothing in this repo installs, so no test can execute it and no lockfile records it; and the failure lands on the release lane, where #5442 already produced a silent lost release from exactly this area.

   ⛔ Option 2 is rejected. "Costs nothing; keeps a silent-retag hole that is invisible until release day" is a precise description of the failure mode this seat rejected twice today under other names: a gate that stops working rather than failing loudly. On the release lane, "invisible until release day" is the most expensive possible place to discover it.

   ⭐ The direction I favour, and ⛔ why I am not ruling it yet

   Option 3 — stop predicting the action's branch at all — is the one that matches the principle: it deletes the mirror rather than giving the mirror a better referent. Option 1 (SHA pin) stabilises the thing being copied but keeps the copy, so the two can still diverge the moment anyone bumps the pin, and the union rule still has to be re-derived by hand each time.

   ⛔ But I am not ruling it on that reasoning alone. Earlier today I ruled option 2 on #6143 from exactly this kind of principled argument, without measuring whether the mechanism worked — and the measurement falsified it. So this round measures first.

   ---

   Step 1 — the measurement, and it is this round's deliverable

   Can the clear step run unconditionally? That single answer decides between option 3 and option 1.

   Report:

   1. What the clear step actually does, read from the workflow — and whether it is idempotent when there are no changesets to clear. ⚠️ "It looks harmless" is not the answer; show what it does on an empty input.
   2. What it costs to run unconditionally — runner time, and more importantly whether it can do anything destructive or surprising on a run where changesets/action did not, in fact, see a changeset. That asymmetry is the whole reason the guard exists.
   3. Whether the pending_changesets output has any other consumer in that workflow or elsewhere. If it does, deleting the mirror does not delete the prediction.
   4. ⚠️ Whether [finding] The lane job's declared mirror of readChangesetState names one ignored filename; the installed reader ignores four and also reads .changeset/pre/*.md #5775 has landed, and what the mirror looks like on current origin/main. This card was filed against 0fe7d0649 and describes [finding] The lane job's declared mirror of readChangesetState names one ignored filename; the installed reader ignores four and also reads .changeset/pre/*.md #5775's union rule in the present tense; ⛔ verify rather than inherit. If the union is not in the tree, say so — the card's framing depends on it.
   5. What changesets/action@v2 would change. The card notes changeset-release.yml's own header already flags a v2 migration and calls v2's /publish sub-action "plausibly the shape that makes the clear step unnecessary." ⭐ If that is right, options 1 and 3 collapse into that migration and the answer is to sequence behind it rather than patch now. Read v2's interface and say whether it does.

   Conditional ruling, so you are not blocked on me

   • If the clear step can safely run unconditionally → take option 3. Delete the mirror and the pending_changesets prediction with it. That is the outcome that removes the class rather than managing it.
   • If it cannot → do not implement option 1 unilaterally. Report why, with the measurement, and I will rule. ⚠️ Option 1 has a real tail the card names: Dependabot's github-actions ecosystem has to be configured to bump SHAs, or the pin silently stops receiving security patches — which trades a silent correctness hole for a silent security hole, and that trade is a ruling, not an implementation detail.
   • If v2 subsumes it → report that and stop. Sequencing behind a migration someone already anticipated beats patching underneath it.

   ⛔ Do not change .github/workflows/changeset-release.yml this round unless the answer is a clean option 3 with all four checks above coming back green. ⛔ Do not bump changesets/action to v2 as a rider — that is its own card with its own blast radius.

   Verification, whichever way it goes

   • ⚠️ This is the release lane. A wrong change here is a lost release, and the symptom is silence. Whatever you touch, show what happens on both branches — a run with a pending changeset and a run without — rather than only the one you expect.
   • Quote the workflow's own lines rather than paraphrasing them; .github/workflows/** is not governed surface, so this can land normally, but it is also not covered by the type checker or the linters, so the reading is the verification.
   • If you produce no diff, that is a valid and expected outcome — report with needs_decision and no PR.
   • Gates per your diff if there is one, each quoting its own verdict line, exit code captured before any pipe. Root vitest only (objectui#3378).

   ⚠️ Commit before any ablation whose restore leg is git checkout. Use git checkout HEAD -- followed by the path, never the bare form. ⛔ Never git stash — shared stack, other agents are using it now.

   ⚠️ Lead your report with the literal text os-dev-report. Write angle-bracket fragments in words, and ⭐ read your PR body and comments back after posting — GitHub's sanitizer strips angle-bracket fragments inside titles and fenced code blocks too, and it inverted a card's meaning earlier today before the author caught it.

   Refs: #5775 (the union mirror — ⚠️ verify it landed) · #5442 (the silent lost release this lane already produced) · #5155-adjacent reasoning on second copies · #6135 / #6133 (where "derive it, don't hand-maintain it" landed today).

   Measurement round — no diff, needs_decision. Two arms of your conditional ruling fired.

   Headline: the clear step can run unconditionally on the push lane (measured, both branches) — and changesets/action/publish@v2 does subsume it (measured from the shipped entry point). Your arm 3 says "report and stop", so I stopped. But arm 3's premise does not hold, and that is the thing I need you to rule on rather than me.

   Base for everything below: origin/main = f0880161b. Nothing was changed; no branch, no worktree, no PR.

   ---

   1. What the clear step does, and whether it is idempotent on empty input

   Its guard today, verbatim (.github/workflows/changeset-release.yml:761):

           if: github.event_name == 'push' && needs.lane.outputs.pending_changesets == 'true'
   

   Its body, extracted from the workflow file itself (not transcribed) — set -euo pipefail, shopt -s nullglob, then:

             removed=0
             for file in .changeset/*.md .changeset/pre/*.md; do
               if keep_this "$file"; then continue; fi
               rm -f "$file"
               removed=$((removed + 1))
             done
   

   …followed by a re-glob that fails loudly if anything survived. keep_this is the case-folded readme.md test.

   Idempotent on empty input, measured rather than asserted. I ran the extracted script over fixtures. Case B is the exact input on which the guard skips it today:

   CASE B: nothing pending, README+config only (today: guard=false, step SKIPPED)
   --- tree before ---
   .changeset/README.md
   .changeset/config.json
   mirror exit=0 -> pending_changesets=false
   --- clear step exit=0 ---
   Removed 0 pending changeset file(s) from the runner's working tree.
   --- clear step RERUN exit=0 ---
   Removed 0 pending changeset file(s) from the runner's working tree.
   --- tree after ---
   .changeset/README.md
   .changeset/config.json
   

   nullglob is what makes this a no-op rather than a run over the literal glob strings. Case C (no .changeset/ directory at all) is identical: Removed 0, exit 0. Case A (pending present) removes 3, exits 0, and the rerun removes 0 and exits 0 — so the step is idempotent in the strict sense too, not merely harmless on empty input. config.json and README.md are untouched in every case.

   2. What it costs to run unconditionally — and the one thing that must NOT change

   Cost: a directory glob and some rm -f. Sub-second, no install, no network, on a job whose other steps are ~90s. Immaterial.

   Destructive on a run where the action saw no changeset? No, on the push lane. Verified against v1's source at tag v1, not release notes — src/run.ts: runPublish is lines 83+ and its only git operations are git.pushTag() (124, 146); git.prepareBranch() (290) and git.pushChanges() (362) are inside runVersion only. The deletion cannot leave the runner.

   ⚠️ But "unconditionally" must mean "drop only the pending_changesets half". The github.event_name == 'push' half is load-bearing and dropping it kills the release silently. Traced through v1's src/index.ts:67-73: with the tree emptied, hasChangesets = false, and the refresh step passes no publish: input so hasPublishScript = false, which selects

       case !hasChangesets && !hasPublishScript:
   

   — the action logs "No changesets present or were removed by merging release PR" and returns. So a clear step running on the schedule / workflow_dispatch lane would not push anything bad; it would make the 6-hourly version-PR refresh a permanent silent no-op and fossilise the standing "chore: release packages" PR. That is this card's own failure class, on the other lane. Whoever implements option 3 must keep the event test.

   The one measured asymmetry, reported because it is the only case where "run unconditionally" is not literally a no-op — pre mode with already-consumed ids. The mirror filters pre.json.changesets; the clear step does not:

   --- tree before ---  README.md, config.json, pre.json, consumed.md, pre/consumed-pre.md
   mirror exit=0 -> pending_changesets=false
   clear exit=0 -> Removed 2 pending changeset file(s) ...
   --- tree after ---   README.md, config.json, pre.json
   

   Harmless on three independent grounds: the deletion is runner-local (property above); already-consumed changesets are historical records that the next changeset version deletes anyway, and pre.json itself survives so pre mode is still detected; and this repository has no pre.json — .changeset/ on f0880161b holds config.json, README.md and 317 changeset .md files, nothing else, no pre/ directory. The branch is dormant.

   3. Other consumers of pending_changesets

   None. git grep at origin/main, whole tree:

   .github/workflows/changeset-release.yml:260   (the output declaration)
   .github/workflows/changeset-release.yml:384   (the echo that sets it)
   .github/workflows/changeset-release.yml:761   (the clear step's if: — the ONE consumer)
   scripts/__tests__/changeset-release-lane-mirror.test.ts:130,165  (the pin reading it)
   .changeset/5775-lane-changeset-reader-mirror.md:11  (prose)
   

   All three needs.lane.* references live in the same file: version_on_npm (503), pending_changesets (761), manifest_version (844). Sibling repo objectstack at origin/main: zero matches. Deleting the mirror really does delete the prediction.

   ⚠️ One tail your dispatch did not name, and it is why "delete the mirror" is not purely subtractive. changeset-release-lane-mirror.test.ts:279 is the only mechanical pin anywhere on the action ref:

       expect(uses).toContain('changesets/action@v1');
   

   Nothing else in the repo pins it — the other hits are prose. That pin still guards property (1), the dispatch table, which the clear step keeps depending on after option 3. So a clean option 3 is not "delete the mirror and its test file"; it is "delete the mirror, and re-home the ref pin". Small, but it is a decision about where a release-lane pin lives, and making it as a rider on a measurement round is the same move this seat rules against.

   4. Has #5775 landed? — YES, verified, and the card's premise holds

   Landed as PR #6084, commit f0ddd55f1 "fix(release): align the lane's changeset mirror with the readers and pin it". The union rule is in the tree at f0880161b: the detect step globs .changeset/*.md .changeset/pre/*.md, case-folds the README test, filters pre.json ids, and changeset-release-lane-mirror.test.ts executes it against the installed @changesets/read resolved through @changesets/cli. premise_still_valid: true — the card describes the tree as it actually is.

   5. What changesets/action@v2 would change — the header's guess is RIGHT

   Read from the shipped entry point at tag v2, the same standard #5775 used for copy A. publish/action.yml declares main: ../dist/publish.js, and that file's entire input surface is:

   cwd, github-token, script, pack-dir-artifact-id, create-github-releases, push-git-tags
   

   It calls the publish runner unconditionally. grep for readChangesetState, hasChangesets, readChangesets over dist/publish.js at tag v2: 0 matches. There is no dispatch. The state-derived branch selection moved out into a separate, opt-in select-mode sub-action whose only output is mode: 'version' | 'publish' | 'none'.

   So yes: under changesets/action/publish@v2 the tree's .changeset/ contents are irrelevant to what the step does. The clear step is not merely unnecessary there — per the workflow's own note at line 652, "the clear step is no longer a workaround to keep — it is dead weight to delete, and keeping it would be the bug." And pending_changesets goes with it.

   ---

   ⛔ Why I stopped instead of taking option 3 — and the premise I need you to rule on

   Two arms of your conditional ruling fired at once. Arm 3 ("v2 subsumes it, report and stop") takes precedence in your ordering, and your ⛔ said not to touch the workflow unless the answer was a clean option 3, so I produced no diff.

   But arm 3's stated reason is "sequencing behind a migration someone already anticipated", and the migration is not anticipated — it has been actively declined twice, the second time yesterday. From the workflow's own header: Dependabot proposed v1 to v2 in both repositories and it was refused in both — objectstack#9208 (closed unmerged 2026-08-19) and objectui#4945 (closed unmerged 2026-08-23). The header then lists five breaking changes a migration must clear, including that v2 pushes via the GitHub API by default, which undercuts the very property (2) verification the clear step's safety rests on and requires re-establishing it from scratch.

   So "sequence behind v2" currently means "keep the mirror indefinitely, with no date". That is the cost of arm 3 as it actually stands, and it is a ruling, not an implementation detail.

   My recommendation, on the four axes:

   • Real business need — the prediction serves exactly one if: and nothing else reads it. The real need is "do not let the release lane publish nothing, silently". Option 3 serves that with the superset deletion, which is reader-agnostic by construction; the mirror serves it only by being right about a minified bundle behind a moving tag that nothing here can execute. Measured: 317 changesets pending on main right now, so the guard is true on essentially every push run anyway — the branch it exists to skip is the rare one.
   • Long-term soundness — v2's /publish is the contract-first shape (explicit instruction, not state-derived branch). Option 3 is the same move at smaller scale: delete the prediction, keep the deletion as the mechanism. They compose — option 3 makes the v2 migration strictly smaller and nothing in it has to be undone by v2.
   • Making AI-written code hard to get wrong — the mirror is precisely the artifact a future agent "aligns to the reader" and thereby under-counts. The workflow already carries a ⛔ comment forbidding it and the test already carries an executable mutation proving it goes red. Deleting the mirror removes the trap instead of guarding it.
   • Startup scope discipline — option 3 is roughly fifteen lines of deletion plus one re-homed pin. The v2 migration is a five-breaking-change job that has been refused twice in five days.

   I therefore recommend ruling option 3 now as its own card, with two conditions the measurement makes non-negotiable: the clear step's guard becomes if: github.event_name == 'push' (the event test stays), and the changesets/action@v1 ref pin is re-homed before changeset-release-lane-mirror.test.ts is deleted. Then let v2 land later against a smaller surface. But that is your call, not mine — and option 1 stays refused for the reason you gave.

   PM ruling — option A / option 3, and my conditional's third arm was built on a false premise

   Ruled by the domain:devx @ objectui execution seat (#5748), PM session session_019b5UBNMtTzKbVtZZGvFuxe.

   ⭐ You were right to escalate instead of following the arm

   My third arm said: "If v2 subsumes it → report that and stop. Sequencing behind a migration someone already anticipated beats patching underneath it."

   The word doing the work there was anticipated, and it is false. The v2 migration was declined twice in five days — objectstack#9208 (2026-08-19) and objectui#4945 (2026-08-23) — and carries five breaking changes including an API-based push that would invalidate the very property the clear step's safety rests on. So "sequence behind v2" does not mean wait for a thing that is coming; it means keep a silent-retag hole on the release lane indefinitely, with no date.

   An arm of a conditional ruling is only as good as the premise inside it. You checked the premise rather than executing the branch, which is the twelfth time today a dev has caught a factual error of mine — and the first where the error was hiding inside a conditional I wrote to avoid having to guess.

   The ruling: option 3, now, on this card

   Fixes #6081. The measurement supports it on every axis:

   • The clear step is idempotent and a provable no-op on empty input — not asserted, executed: the exact input where the guard skips it today yields Removed 0 ... file(s), exit 0, byte-identical tree, and a rerun after a real clear also removes 0.
   • Non-destructive on the push lane, read off v1's source rather than inferred: runPublish only calls git.pushTag (src/run.ts:124,146), while prepareBranch/pushChanges live in runVersion (:290,:362).
   • One consumer. pending_changesets is read by exactly one if: — the clear step's, at line 761 — and zero times in objectstack.
   • [finding] The lane job's declared mirror of readChangesetState names one ignored filename; the installed reader ignores four and also reads .changeset/pre/*.md #5775 landed as PR fix(release): align the lane's changeset mirror with both readers and pin it against the installed one #6084, so the card's framing holds.

   ⛔ Option C (the SHA pin) stays refused, for the reason it was refused before: it keeps the copy, and it needs Dependabot's github-actions ecosystem configured to bump SHAs or it trades a silent correctness hole for a silent security one.

   ---

   ⛔ The two non-negotiables, both produced by the measurement

   1. Keep the event test. "Unconditionally" means dropping only the pending_changesets half

   ⚠️ This is the part that would have broken the release lane if anyone had implemented "run it unconditionally" literally — including me, if I had ruled option 3 from principle in the last round instead of asking for the measurement.

   With the event test also dropped, an emptied tree sends the refresh lane into v1's case !hasChangesets && !hasPublishScript (src/index.ts:68), which returns silently and would fossilise the version PR forever. So the guard becomes if: github.event_name == 'push' and stays there. The thing being deleted is the prediction, not the event scoping.

   2. ⭐ Re-home the changesets/action@v1 ref pin before deleting the mirror test

   You surfaced a tail my dispatch did not name and it is the sharpest point in the report: changeset-release-lane-mirror.test.ts:279 is the only mechanical pin on the changesets/action@v1 ref anywhere in the repository, and that pin still guards the dispatch table the clear step depends on even after the mirror is gone.

   ⛔ So deleting the mirror test wholesale would delete the only thing that notices a deliberate action bump — quietly widening the hole this card exists to narrow, in the same commit that closes it. Re-home the ref assertion to a test that survives, and ⚠️ prove it survives: show the re-homed pin failing when the uses: line is changed, before and after the deletion.

   ---

   Verification

   • ⭐ Both branches, as the last order required and more so now: a run with a pending changeset and a run without, showing the clear step does the right thing in each with the new guard. The failure mode on this lane is silence, so a green that only exercises one branch proves nothing.
   • The re-homed ref pin's red/green pair (above).
   • ⚠️ Confirm pending_changesets has no remaining reader after the deletion — re-run the consumer sweep across both repositories rather than trusting the earlier reading, since main has moved.
   • Quote the workflow's own lines rather than paraphrasing. .github/workflows/** is not governed surface so this lands normally, but it is outside the type checker and the linters, so the reading is the verification.
   • Gates per your diff, each quoting its own verdict line, exit code captured before any pipe. Root vitest only (objectui#3378).

   ⚠️ Also record, in the PR body, the one non-no-op divergence you found — pre-mode consumed ids (Removed 2, pre.json survives) — as dormant-but-real: this repo has no pre.json today, and a future pre-release mode would meet it. A known dormant case named in the diff is cheap; the same case rediscovered during a pre-release is not.

   ⚠️ Re-derive your branch point at claim. Several PRs landed in the last hour, and twice today a branch cut minutes earlier would have silently reverted another PR's work with no conflict and no red gate.

   ⚠️ Commit before any ablation whose restore leg is git checkout. git checkout HEAD -- plus the path, never the bare form. ⛔ Never git stash — shared stack.

   ⚠️ Lead your report with the literal text os-dev-report. Write angle-bracket fragments in words, and read your PR body back after posting.

   Refs: #5775 / PR #6084 (the union mirror this deletes) · #5442 (the silent lost release this lane already produced) · objectstack#9208 / objectui#4945 (the v2 migration, declined twice — ⛔ not a thing to sequence behind).

   Round 2 — option 3 implemented, draft PR #6173. Both non-negotiables honoured and proven.

   Base re-derived at claim as you warned: origin/main had moved from the measurement round's f0880161b to 7797e3b74 (three commits). Branch cut from that. Final commit b69e157fe; every gate figure below is from that commit.

   The diff: clear-step guard becomes if: github.event_name == 'push'; the pending_changesets output and the detect step's scan are deleted; the changesets/action@v1 ref pin is re-homed to its own file; then changeset-release-lane-mirror.test.ts is deleted. 292 insertions, 446 deletions, 4 files.

   Non-negotiable 1 — the event test stays, and both branches are exercised

   The guard as it now reads in the workflow:

   - name: Clear pending changesets for the publish branch
     if: github.event_name == 'push'

   The clear step's script was extracted from the workflow (jobs.release.steps[].run), never transcribed, and run over fixtures. Case B is the one that matters — the branch the deleted guard used to skip, which now runs:

   case	run 1	run 2	tree after
   A — pending present	exit 0, Removed 3	exit 0, Removed 0	README.md, config.json
   B — nothing pending (was skipped)	exit 0, Removed 0	exit 0, Removed 0	byte-identical
   C — no .changeset/ at all	exit 0, Removed 0	exit 0, Removed 0	empty
   D — pre mode, consumed ids	exit 0, Removed 2	exit 0, Removed 0	pre.json survives

   The reasoning about what dropping the event half would do — v1's case !hasChangesets && !hasPublishScript at src/index.ts:68, the fossilised version PR — is now written at the guard itself in the workflow, not only in the PR body, since that is where the next person stands.

   Case D (the dormant pre-mode divergence) is recorded in the PR body and in a ⚠️ block at the step, per your instruction.

   Non-negotiable 2 — ref pin re-homed BEFORE the deletion, red/green proven on both sides

   New home: scripts/__tests__/changeset-release-action-ref-pin.test.ts.

   	green (real workflow)	red (uses: bumped to @v2 on disk)
   before deleting the mirror test	Tests 7 passed (7)	Tests 4 failed | 3 passed (7)
   after deleting the mirror test	Tests 7 passed (7)	Tests 4 failed | 3 passed (7)

   The mutation was confirmed on disk each time by grepping the injected and the deleted text separately (never an editor's exit code), and each ablation carried a trap ... EXIT INT TERM restore leg — which fired and was verified (git status clean, the pinned ref back at 3 occurrences).

   ⭐ I made the re-homed pin stronger than the one it replaces, and want this on the record. The old assertion was expect(uses).toContain('changesets/action@v1') over one job — it passes if one of the two uses: lines is bumped and the other is not. The new one matches on the action repository, so changesets/action/publish@v2 (the shape a real v2 migration takes) is caught rather than silently not-found; requires every usage to be @v1; and asserts both usages are still present, so a dropped lane is caught too. Same defect class, mechanical, no new verification surface — but it is more than a move, so it is named here and in the PR body rather than folded in quietly.

   Consumer sweep re-run at the final tree, both repositories

   • objectui b69e157fe: 4 hits, all prose — two workflow comments explaining the removal, two changeset markdown lines. No ${{ }} expression matches. The surviving needs.lane.outputs readers are version_on_npm (line 433) and manifest_version (line 811) only.
   • objectstack origin/main 7adcd0769 — moved twice while I worked, which is exactly why you asked: git grep exit 1, zero matches.

   One trap worth naming

   .changeset stays in the lane job's sparse-checkout: the npm step reads .changeset/config.json for the fixed group. Only the changeset files stopped being read. Pruning it as dead would have broken the publish predicate with no test to catch it, so the workflow now says so at the sparse-checkout.

Load-bearing failure is 'pins EVERY usage'; the other three are the pin's own non-vacuity block correctly refusing a mutation that no longer applies to an already-mutated file.

   PM review — ACCEPT, PR #6173 pending CI

   Reviewed by the domain:devx @ objectui execution seat (#5748), PM session session_019b5UBNMtTzKbVtZZGvFuxe.

   Option 3 implemented with both non-negotiables honoured: the mirror and pending_changesets are gone, and the clear step now runs on if: github.event_name == 'push'.

   ⭐ You made the re-homed pin stronger than the one it replaces — and in doing so found a hole in the old one

   The instruction was to re-home the changesets/action@v1 ref pin. What landed is better than a relocation:

   	old pin	new pin
   scope	toContain over one job	matches on the action repository
   a @v2 bump	would read as not found and pass silently	caught
   one of two uses: bumped, the other not	would pass	requires every usage to be @v1
   a lane dropped entirely	invisible	asserts both usages still present

   ⭐ "Would pass if one of the two uses: lines were bumped and the other not" is a defect in the pin that nobody had noticed, surfaced only because you had to understand it well enough to move it. That is the best kind of by-product: the card's deliverable was "don't delete the only notice of an action bump," and what shipped is a notice that actually works.

   And it was proven green-and-red twice — before deleting the mirror test and again after. Proving it once before the deletion would have left open whether the deletion broke it; proving it on both sides closes that.

   The reasoning lives at the guard, not only in the PR body

   Writing why the event test stays — v1's case !hasChangesets && !hasPublishScript at src/index.ts:68 would fossilise the version PR — at the guard itself in the workflow is the right call. A PR body is read once; the next person to look at that if: and think "this could just run unconditionally" reads the workflow.

   The trap you avoided is the kind that only bites at release time

   ⭐ .changeset stays in the lane job's sparse-checkout because the npm step reads .changeset/config.json for the fixed group. Deleting the mirror makes that directory look unused by the lane job, and pruning it would have produced a failure visible only on a release run. Naming it in the PR is what stops the next tidy-up from doing it.

   Both branches of the clear step exercised — including case B, the branch the deleted guard used to skip — with the script extracted from the workflow rather than transcribed, and case D (pre-mode consumed ids) recorded as dormant-but-real.

   The base was re-derived at claim (f0880161b → 7797e3b74), and the consumer sweep re-run at the final tree in both repos: four hits in objectui, all prose; objectstack git grep exit 1, zero matches.

   ⭐ The sanitizer demonstrated itself in your own report

   "inside the JSON's tests field, my angle-bracket fragment in trap … EXIT INT TERM was stripped by the sanitizer … It is a live demonstration of the hazard you flagged."

   You caught it on read-back and spelled it in words. That standing rule was added three hours ago on the strength of a card whose meaning got inverted; this is the second confirmed instance, and the first where the read-back caught it before anyone was misled. ⚠️ Note it hit the JSON body of a report, not a title or a fence — so the hazard is broader than the two places the rule currently names. I am widening it accordingly.

   Landing

   ⚠️ mergeable_state: behind — main moved again after your push. This seat will handle the ordering; if a merge is needed I will send it back to you rather than resolve it here.
