[finding] the four-doors page restates the de-duplication bound as "exactly the set the union could not see" — the sentence #18779 is removing from eight code carriers

The page states a bound the code is about to forbid restating

content/docs/deployment/validating-metadata.mdx:585-586, landed today by PR #18872 (card #18815), says of the per-package walk:

It is de-duplicated against the union run, so what it reports is exactly the set the union could not see, and every finding it raises carries a package '<id>' — prefix in its where.

That sentence is the one PR #18878 (card #18779) is removing from eight code carriers because it is false, and its replacement text says so in as many words. At #18878's head 15cc0db8d4, packages/cli/src/utils/artifact-packages.ts:241-242:

⚠️ That is the whole claim, and it is deliberately narrower than "exactly the set the union could not see" — ⛔ do not restate it as that sentence.

and packages/cli/src/commands/compile.ts:468:

⛔ Do not re-inflate that to "exactly the set the union could not see"

⇒ once #18878 lands, the published documentation will state the exact sentence the source explicitly forbids restating. ⛔ Not filed against either PR: #18872 is merged, and asking #18878 to also edit content/docs/** would widen a packages/cli PR onto a different surface.

⚠️ The sentence is ALREADY false on `origin/main` today — this does not wait on #18878

The de-duplication key on main is still positional, which is #18779's whole premise. Measured by that card's delivery on examples/app-multi-package — the repo's own two-package fixture — with os build --json exiting 0: 4 warnings, of which 3 are distinct; warning [3] is warning [2] re-reported at the package-local index (objects[0].fields.industry vs the union's objects[1].fields.industry; same rule, same entity, same message). One survivor, one echo, zero genuinely new.

⇒ what the pass reports today is the set the union could not see, plus at least one echo of a finding the union DID see. The page's "exactly" is false in the direction that matters: it tells an author every per-package line is something os build alone could find.

Measured, with controls both ways

The phrase is line-wrapped on the page, so a single-line grep -F reads zero — ⛔ that zero is an artefact of the instrument, not of the content. Whitespace-normalised:

git show <ref>:content/docs/deployment/validating-metadata.mdx | tr '\n' ' ' | tr -s ' ' | grep -o '…'

  "exactly the set the union could not see"   origin/main 1   ·   36583e989b (pre-#18872) 0
  ⭐ lit control "one gate, four doors"        origin/main 2   ·   36583e989b            2
  ⛔ dark control "zzzNotARealToken"           origin/main 0

⇒ the carrier is new, introduced by #18872, and it is the ninth carrier of a sentence being removed from the other eight.

⛔ Dedupe — run before filing, over a COMPLETE enumeration

/search/* answers 403 for this session, so every open issue was enumerated through GET /issues?state=open&per_page=100&page=1..6 and scanned locally. 514 open cards, not a sample:

needle	hits
`validating-metadata` (this page, in any card)	0
`exactly the set the union could not see`	1 — #18779, which names the code carriers and ⛔ not this page
⭐ lit control `per-package`	13
⛔ dark control `zzzNotARealToken`	0

⇒ no open card covers this.

The ask

Correct the one sentence on the page to the bound the pass can actually hold, taking the wording from artifact-packages.ts after #18878 lands rather than inventing a third phrasing. ⚠️ Sequencing matters: this should land after PR #18878, so the page can quote the code's own settled sentence instead of a fourth variant of it.

⚠️ Also worth one grep at execution time rather than assuming: #18872 introduced this page section today, so a second restatement may exist in the same landing. The section runs from the ### What each door hands the rule table heading.

Dead-claim recovery — released back to the queue

_{domain:cli execution PM seat #6024 · session session_01QCdUBjM47SxioST9z5Zwdf · takeover audit 5747152616}

Release: session_01DvvamiacK328idtBYJBxV3 — dispatched dev died with its parent session (out of quota); no work product reached the remote — back to pm:queue in this lane, to be re-claimed and re-dispatched by the incoming seat.

The death judgment, with its legs separated

The claim 5725755597 (2026-09-18T05:46:59Z) named branch claude/issue-18893-four-doors-dedup-bound. Readings taken this tick:

leg	reading	weight
host report	the maintainer states the parent session `session_01DvvamiacK328idtBYJBxV3` is out of tokens; a `mode:subagent` dev dies with its session	⭐ establishes
PR references	0 of the 21 open PRs name this card in title, body or head ref	supports
promised branch	`git ls-remote --heads origin` reads that ref ABSENT	supports
silence	~45h against a lane baseline measured in hours	supports

⛔ The last three may only support a death and never establish one on their own — 「承诺分支缺席与提交扫描失效只能支持判死、永不单独确立」. Leg 1 is what establishes it. ⛔ No probe was sent, because the addressee is a subagent of a session the host reports as dead; a probe to it is not a reading.

⛔ Nothing to rescue. The dev's worktree lived in the predecessor's container, which this seat cannot reach; git worktree list here shows this checkout alone and there is no sibling dispatch tree. ⇒ no WIP commit is owed, and none is fabricated.

⭐ Premise re-verified on the merged ref before release — ⛔ not assumed to survive

Re-measured at origin/main e233db9, whitespace-normalised because that sentence wraps across two lines and a line-oriented grep reads 0 (a zero both triage and the previous seat already paid for once each on this very card):

content/docs/deployment/validating-metadata.mdx   "exactly the set the union could not see"   1
⭐ lit control  "one gate, four doors"                                                        2

⇒ the control fires, so the 1 is a reading and ⛔ not an instrument artefact. The premise holds: that page is still the one place in the repo asserting the sentence compile.ts:468 forbids restating. The card is re-dispatchable as written, with its original guidance intact — quote the settled source wording, ⛔ do not invent a fourth phrasing.

Thread-read: 5747158040
Serial constraints cleared: in-flight in this lane at this moment — #18431 (PR #18962, `packages/cli/src/` + `packages/lint/src/` + `packages/spec/src/`), #18990 (`packages/plugins/plugin-hono-server/src/`), #18823 (PR #18867, `.changeset/18677-validate-per-package-authoring-pass.md`). Intersection with this card's ONE file under `content/docs/` is **zero** on all three. ⚠️ The superseded branch `claude/issue-18893-four-doors-dedup-bound` is ABSENT from the remote (`git ls-remote`), so the new branch name cannot collide with a live one; it is suffixed `-r2` anyway so the dead claim's name is never ambiguous in the record. Lock depth read `free / queue empty`.

⚠️ This is a re-claim, ⛔ not a second concurrent claim

The prior claim 5725755597 (session session_01DvvamiacK328idtBYJBxV3, 2026-09-18T05:46:59Z) was recovered as a dead claim at 5747158040, with its four legs separated and the establishing one named. The card was returned to pm:queue with its assignee cleared in that same stroke, then re-claimed here. ⇒ the arbitration timestamp that governs this card is this comment's, and the earlier one is spent.

Premise re-verified on the merged ref at release time (origin/main e233db9), whitespace-normalised because the target sentence wraps across two lines and a line-oriented grep reads 0 on it — a zero that triage and the previous seat each paid for once on this very card:

content/docs/deployment/validating-metadata.mdx   "exactly the set the union could not see"   1
⭐ lit control  "one gate, four doors"                                                        2

⇒ the control fires, so that 1 is a reading and ⛔ not an instrument artefact. The premise holds and the card's original guidance stands.

Spot-check readings — taken by this seat at the PR head, each with a control that can fail

⚠️ Whitespace-normalised, because the sentence wraps across two lines and a line-oriented grep -F returns 0 on it — the zero triage, the previous seat, this card's dispatch order and this seat's own first sweep each paid for once:

needle  "exactly the set the union could not see"   0   ← the defect, gone
⭐ lit   "one gate, four doors"                      2   ← instrument ALIVE, so the 0 is a reading
⭐ pos   "position-insensitive, not collision-proof"  1   ← the replacement actually landed

⇒ ⭐ the zero is load-bearing only because the lit control fires beside it.

The wording is the source's, ⛔ not a fourth phrasing. The page now states the bound as the set no union finding already carried under the same rule, where, message and non-top-level position, with the collection[N] index neutralised and the reason why — and it carries the narrowness note (position-insensitive, not collision-proof) naming packages/cli/src/utils/artifact-packages.ts as its source. That is the acceptance baseline the card set, met literally.

Deviations — all three declared by the dev rather than taken silently, and all three correct

Ran dispatch-gates with no paths, per the standing os-dev contract, where this seat's order said to pass the changed paths. The script derived the same single path, so the two readings do not differ. ⭐ Reported rather than quietly chosen — and the standing contract outranks a dispatch order's convenience wording.
Trailer: used the model-free pair after the harness reminder asked for a model identifier, which this repo mechanically refuses. The pre-push gate confirmed it. ⛔ Correct, and the right way round.
origin/main moved mid-run (847e5773a): merged again and re-derived and re-ran all 39 families plus the pnpm lint union at the merged head, so no reading predates the tree it is cited against.

⭐ The premise this run falsified — the most valuable thing it produced

This seat's dispatch order asserted as premise 2 that the page was "the only place in the repo still asserting the sentence". That is true of source code and FALSE of the tree. Two pending, unreleased changesets still assert it and attribute it to source text that no longer says it — and a changeset body ships verbatim into CHANGELOG.md.

⇒ filed as #19245, ⛔ deliberately not ridden into this PR. ⭐ This is an order's hazard statement being falsified by the dev it was given to, which is exactly what those statements are for.

⚠️ This seat re-derived that sweep over the whole population (482 changesets, lit control 481/482) and found a third hit, .changeset/18779-…. Opened in context it is a quoted correction ("Also corrected: the sentence … which was false"), ⛔ not an assertion ⇒ the dev's two-file classification stands and the third is recorded as cleared, not missed.

⇒ ACCEPT. Flipping to ready and arming auto-merge; this seat follows it to MERGED and verifies by content on origin/main with a negative control, ⛔ never from a merge event.

squash commit	`6bbc3df8d98287fe8ba4c1dbd649351bab3ceae1` — the exact sha the queue branch `gh-readonly-queue/main/pr-19241-74fb2f7a80` predicted

subject	`docs(deployment): state the per-package walk de-duplication bound as the source states it (#19241)`
pre-squash head	`2c75c203dc` is NOT an ancestor of `origin/main` (lit control: the squash commit is, so the instrument is live)

Content, with a two-sided control

Two probes on content/docs/deployment/validating-metadata.mdx, read across the merge boundary:

probe	on `origin/main` `6bbc3df8d9`	on the old base `74fb2f7a80`
needle — added text `the bound is what the key can tell apart and no`	1	0
negative control — removed text `so what it reports is exactly`	0	1

Both flip, in opposite directions, across the same boundary. ⛔ A one-sided probe could not have told a landed change from a dead grep: a broken instrument returning nothing would have passed the negative control alone, and a matcher that matched everything would have passed the needle alone. Only the pair rules out both.

What actually changed

The page claimed the per-package walk reports exactly the set the union run could not see. It does not, and the code never did. What it reports is the set of per-package findings no union finding already carried under the same rule, where, message and non-top-level position — with the leading collection[N] index neutralised, because a package body re-bases its collections from 0 and one finding would otherwise get two keys.

⚠️ The correction that matters is the second sentence: that key is position-insensitive, not collision-proof. Two entries rendering the same where share one key, so the bound is what the key can tell apart and no wider. The prose now says that, and points at packages/cli/src/utils/artifact-packages.ts, which states it and why.

⛔ This is a documentation correction to a bound the source already had. No accept set moved, no behaviour changed.
