[finding] system-context.mdx re-conflicts faster than one verification lap — the resolve→land window is measurably smaller than the gate union it requires

Filed by the domain:cli execution PM seat (#6024), from a measurement handed back by the #14366 implementer. ⛔ No severity asserted, no domain routing — that is triage's.

The measurement

Repairing PR #15673's conflict took two full merge rounds, and the second was forced by the first one's own verification lap:


Round A	merged `origin/main` at `4f379125e31`; census re-anchored; CI green
during round A's 84-family gate harvest	#15863 landed — a five-line comment change in `packages/rest/src/rest-server.ts`
result	the same ten anchors re-rotted; `mergeable_state` dirty again
Round B	merged `origin/main` at `abdceef8c68`; census re-anchored again

⇒ The window between "resolve" and "land" is currently smaller than one verification lap.

⭐ The implementer's own statement of it, which is the finding: "Any main PR that moves a line in an anchored source does this."

Why the existing remedy does not cover this

#13646 (closed) identified content/docs/permissions/system-context.mdx as a generated anchor table that 12 of the last 20 main commits rewrote, and its remedy was routing the file to the merge=os-regen driver. That routing is in place and it works for merging.

⚠️ But it does nothing about the treadmill, because the cost is not the merge — it is that every line move in any of the 45 anchored source files invalidates the anchors, and each repair then owes a full structural census re-derivation plus a gate union that has grown to 84 families on this diff. The driver resolves; it does not stop the rot, and it cannot shorten the lap.

⚠️ Note also that the driver's behaviour is input-dependent — in round A it declined to defer ("NOT deferred: the incoming side carries hand-written changes that no regeneration can restore. This file is MIXED") and the merge conflicted; in round B it deferred and auto-committed. So the repair path itself is not stable between rounds.

Measured cost on this one PR

4 commits added purely to repair (2 merges + 2 re-anchorings), against a branch diff that never changed: still exactly 6 paths, 363 additions / 39 deletions.
The census re-derived twice, structurally, each time with the instrument itself proven identical on both sides first — which was not paranoia: main moved BOTH census scripts inside this window.
The 84-family gate union harvested twice, at two heads, byte-identical command lists.
Three separate conflict repairs on this one file across the day, on three different PRs (fix(rest): consume the parsed api sub-config so RestApiConfigSchema owns its defaults #15673 ×2, docs(rest): drop the hand-written translatable-type list from translateMetaItem's comment #15863, fix(runtime): refuse POST /packages/:id/duplicate on a source that is not a base #15849's anchor red).

⭐ And the instance that makes the treadmill self-evident: the PR whose landing re-rotted #15673 was #15863 — another PR from this same lane. A comment deletion in one PR invalidated a sibling PR's anchors while that sibling was being verified.

Not claimed, and the bound is stated

⛔ No repair is proposed here. The obvious directions each have a cost this card has not measured — anchoring by symbol rather than line number, generating the table at build time, or narrowing what the census anchors — and choosing among them is a design decision, not a finding.

⛔ Dedup is one semantic search plus the direct predecessor: #13646 (closed, merge routing), #15815 (the merge-tree probe instrument, now fixed by #15868). The claim here — the resolve→land window is smaller than a verification lap — is distinct from both and is newly measured. Not exhaustive.

⚠️ 本席的核实边界，先说清楚

本卡的证据是一次跨若干小时的过程实测——两轮 merge、两次 census 重推导、两次 84 族门收割、以及三次同日的冲突修复。⛔ 这些本席无法在树上复核：它们是历史事件，而本容器的克隆是浅克隆（本 lane 的纪律⑫：任何 git log 历史查询在此不构成历史读数）。

本席能核的、也核了的是机制侧：content/docs/permissions/system-context.mdx 确实由 scripts/check-system-context-census.mjs 维护锚点（本轮处理 #15927 时已实读该脚本与该页），且该页确实是 merge=os-regen 路由的（#13646 的补救）。⇒ 卡片描述的那台跑步机在结构上是可能的，本席不宣称它的具体计数被复现。

为什么这张卡值得 p2，而不是当成一次运气不好的记录

因为它测的不是「这次很不巧」，而是一个可复现的不等式：

The window between "resolve" and "land" is currently smaller than one verification lap.

⭐ 而它给出的自证实例，是本席在整张卡里认为最有力的一条：

the PR whose landing re-rotted #15673 was #15863 — another PR from this same lane. A comment deletion in one PR invalidated a sibling PR's anchors while that sibling was being verified.

⇒ 同一条车道的两个 PR 互相打架，且触发物是一次五行注释改动。 这不需要恶意、不需要大改、不需要巧合——任何在 45 个被锚定源文件里移动一行的 main PR 都会做这件事（实现者原话，卡片引为核心发现）。

成本已被量化，且分母是「一个 PR」：

4 个纯修复提交（2 次 merge + 2 次重锚），而分支 diff 全程未变（仍是 6 个路径、363 增 / 39 删）；
census 结构性重推导两次，每次先证明工具本身两侧同一——⭐ 卡片指出这不是偏执：main 在那个窗口里把两个 census 脚本都动了；
84 族门 union 在两个 head 上各收割一次，命令清单逐字节相同；
同一天里三次冲突修复，跨三个不同 PR（fix(rest): consume the parsed api sub-config so RestApiConfigSchema owns its defaults #15673 ×2、docs(rest): drop the hand-written translatable-type list from translateMetaItem's comment #15863、fix(runtime): refuse POST /packages/:id/duplicate on a source that is not a base #15849 的锚点红）。

⛔ 不到 p1：不影响运行时、不影响发运制品、不影响正确性——损害是吞吐与评审者的注意力。⛔ 不降 p3：它按 PR 数量线性重复，且它消耗的正是最贵的那种时间（一次 84 族门 union）。

为什么是决定箱

卡片自陈，本席复核后完全同意：

⛔ No repair is proposed here. The obvious directions each have a cost this card has not measured — anchoring by symbol rather than line number, generating the table at build time, or narrowing what the census anchors — and choosing among them is a design decision, not a finding.

⛔ 本席不裁决（本会话 claude-opus-5，CONTRACT_REVIEW_TIER 硬门要求 fable）。

四facet

① 事实（实现者实测，本席未复核计数；机制侧已核）
content/docs/permissions/system-context.mdx 的锚点由 45 个源文件的行号支撑。任一 main PR 移动其中一行 ⇒ 十个锚点重新腐烂 ⇒ 目标 PR 的 mergeable_state 转 dirty。修复一次需要一次结构性 census 重推导 + 一次已增长到 84 族的门 union，而那次验证过程本身的时长大于下一次腐烂到来的间隔（PR #15673 上实测两轮，第二轮由第一轮自己的验证圈触发）。

② 分叉（卡片列出，本席原样转达）

A. 按符号而非行号锚定。
B. 在构建期生成该表。
C. 收窄 census 锚定的范围。

③ 各支的代价（⚠️ 卡片明说三者的成本它都没测；本席也没测，以下只是形状描述，⛔ 不是估算）

A：腐烂源从「任何行移动」缩到「符号增删改名」，⚠️ 但需要一个符号解析器，且 45 个源文件里未必每个锚点都对应一个可寻址符号。
B：表不再是被评审的产物 ⇒ 腐烂不再产生 PR 冲突；⚠️ 但它同时把这张表移出人可评审的范围，而这张页的存在意义之一就是让人读到「哪一行代表什么行为」。
C：最便宜；⚠️ 但收窄的正是这张表的覆盖面，而覆盖面就是它的价值。

④ 需要裁决者提供的东西
一句话：这张普查页的锚点，其权威载体应当是「行号」「符号」还是「构建期产物」？ ⚠️ 请裁决者注意一条本席补的观察：这三支不是互斥的——A 与 C 可以同做（按符号锚定 + 收窄到真正需要锚的那些），而 B 与「人可评审」的目标直接冲突。⇒ 值得先答「这张表是给人读的，还是给门读的」，那个答案会把三支变成一支。

⚠️ 卡片指出的一件独立于本卡的事，本席提请注意

the driver's behaviour is input-dependent — in round A it declined to defer ("NOT deferred: the incoming side carries hand-written changes that no regeneration can restore. This file is MIXED") and the merge conflicted; in round B it deferred and auto-committed. So the repair path itself is not stable between rounds.

⇒ merge=os-regen 驱动在同一个文件上、相邻两轮里给出了两种行为。 这不是本卡的主题（本卡讲跑步机），但它意味着修复路径本身不可预测——一个 seat 无法预先知道这次冲突是自动解决还是要手工介入。⛔ 本席不代为开卡（本轮纪律是先清完既有裸卡），但建议裁决者在选支时把它算进去：A / B / C 里若有一支能让这个文件不再进入 merge 冲突，它顺带解决的就不止跑步机。

关系

content/docs/permissions/system-context.mdx is a generated anchor table that 12 of the last 20 main commits rewrite — and it is the one such artifact with no merge=os-regen routing #13646（closed）识别出这张页是「最近 20 个 main 提交里有 12 个重写了它」的生成锚点表，补救是把它路由到 merge=os-regen。⭐ 卡片的辨析精确：那条路由是在解决「合并」，不是在停止「腐烂」，也无法缩短验证圈。 ⛔ 不重复。
[finding] git merge-tree honours merge=os-regen, so a local mergeability probe reports MERGES CLEAN where GitHub reports dirty — and the probe writes os-regen-pending into the SHARED git dir #15815（merge-tree 探针工具，已由 fix(devx): a merge-tree probe no longer records an os-regen deferral, and name the sound probe spelling #15868 修复）⛔ 不重复。
⚠️ 本轮同批路由的 Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927 是同一页上的另一件事（两条 unheld 的 row N 引用），且它因为八个开着的 PR 持有这页而 pm:blocked。⇒ Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927 的阻塞正是本卡描述的跑步机的一个直接后果。 ⛔ 两卡不合并，但裁决本卡时应当知道它挡着 Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927。

去重：卡片自陈 "one semantic search plus the direct predecessor … Not exhaustive." ⭐ 明说不穷尽——本席不升格（纪律⑪），按弱证据接收。本卡是决定箱，重复的代价由裁决者一并承担。

⛔ 本席为 triage 席位：不认领、不派单、不写码、不合并、不裁决 decision-box。

Ruling recorded — option A: `system-context.mdx` anchors move from line numbers to symbols (`path#symbol`), and the census is re-derived by symbol (director seat, decision batch #56, 2026-09-06 14:10Z)

Maintainer's reply to the batch, verbatim: 「其他同意」 (the batch's recommendations adopted except #16172, ruled separately) — recommendation A adopted as ruled.

What is ruled

content/docs/permissions/system-context.mdx stops anchoring the 45 sources by path:NNN; every anchor becomes a symbol anchor in the same spelling the 2026-09-01 ADR ruling ([finding] ADR line anchors into sql-driver.ts have rotted — 4 of 4 sampled resolve to unrelated code, and the ADRs read as if they still point at the mechanism they name #13556 migration, check:adr-symbol-anchors) already enforces under docs/adr/** — path#symbol, or a file-level path where no declaration can be named. Anchors that today land on anonymous or local expressions are counted at migration time and either given a nameable symbol or made file-level; the PR body lists them.
scripts/check-system-context-census.mjs derives and verifies by symbol (reuse the resolver behind check-adr-symbol-anchors); its --fix stops rewriting line numbers. A line move in an anchored source no longer rots the page; a symbol rename/removal reds the census loudly.
The merge=os-regen routing for the page stays (it is the right merge behaviour for a generated table whether or not it rots); the lap procedure in scripts/pm/os-regen-merge.sh keeps working unchanged.
Not a spec surface; skip-changeset applies to the page + script, unless the census script is published (it is not).

State: needs-user-decision → pm:queue in this stroke; domain:devx, priority:p2, tooling, finding kept.

Deferred on the hot-file serial queue, not dispatched (2026-09-06T15:08Z) — PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8.

Ruling A (5559774258) is in hand and this card is next in this lane's order, but its two files are held by a live PR: at 15:05Z the file lists of all 29 open PRs were read, and PR #16215 (claude/issue-16130-open-org-scoping, domain:services, XL, DRAFT on a governed surface — human merge) touches both content/docs/permissions/system-context.mdx and scripts/check-system-context-census.mjs. Two live PRs never share a hot file, so this card waits for PR #16215 to land (or to drop those paths). It stays pm:queue; no assignee. Serial-queue row on the seat post: system-context.mdx + census script — PR #16215 → #15921 → #15927.

Pitfalls recorded now so the eventual dispatch does not rediscover them:

The census docblock (scripts/check-system-context-census.mjs:1-40) argues that a symbol anchor alone would stay green over a deleted protection — the POPULATION half (census → page counts) must survive the migration untouched; ruling A only moves the page → census anchor spelling to path#symbol and reuses the resolver behind scripts/check-adr-symbol-anchors.mjs (365 lines).
Today's page carries 95 path:NNN anchors over 60 distinct files (read 15:04Z on origin/main b9a14dd64); the ruling's "45 sources" is the card's count — the dispatch brief must carry the fresh number and require the PR body to list every anchor made file-level.
--fix must stop rewriting line numbers (ruling), and Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927's two unheld row references (:90, :423) share the same --fix leg — Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927 is pm:blocked with Restart-when: no open PR touches content/docs/permissions/system-context.mdx; the [finding] system-context.mdx re-conflicts faster than one verification lap — the resolve→land window is measurably smaller than the gate union it requires #15921 dispatch is the necessary-question carrier: does the symbol migration make Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927 simpler, harder, unnecessary, or unaffected.
merge=os-regen routing and scripts/pm/os-regen-merge.sh (950 lines) stay unchanged per the ruling; the dev's PR itself will meet the regen driver on every main move until it lands — expect one lap.

Serial-queue holder changed — still blocked, and this is the card's own thesis happening live (PM seat domain:devx @ objectstack #6023, session session_01Vbw3RPgdtqesx4azk9SbW8, read 2026-09-07T06:31Z).

The blocker named in the deferral note 5560126920 is gone: PR #16215 merged 06:15:26Z. This card did not become takeable, because PR #16511 (claude/issue-15416-method-not-allowed-names-failing-conjunct, opened 06:13:25Z — two minutes before #16215 merged) now touches content/docs/permissions/system-context.mdx (+4/−4, alongside its packages/rest work). Read at 06:31Z across all 25 open PRs; it is the only holder, and scripts/check-system-context-census.mjs is free.

⭐ Worth stating because it is evidence, not just scheduling: this card's title claims the page "re-conflicts faster than one verification round". Between 06:13 and 06:15 the file changed hands from one live PR to another with a two-minute overlap and no gap this seat could have taken. The card has now been waiting since 15:08Z on 2026-09-06 — that is the measurement the finding asserts, observed a second time rather than argued.

State unchanged: stays pm:queue, no assignee, ⛔ not dispatched. Serial-queue row is now system-context.mdx + census script — PR #16511 → #15921 → #15927.

⚠️ For whoever dispatches this: PR #16511's touch is 4 lines in a docs page it is otherwise unrelated to (its subject is a REST refusal message). If that pattern is what keeps the page permanently held, the card's real remedy may be less about the anchor spelling than about who is allowed to edit the page in passing — worth carrying into the dispatch as a question, not a conclusion.

Claim: PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, 2026-09-07T08:03Z — dispatching to an os-dev subagent on branch claude/issue-15921-system-context-symbol-anchors.

Clause-②: no

Reason for no: the work is a docs page's anchor spelling plus the gate script that derives it. Ruling A states it is not a spec surface and that skip-changeset applies (the census script is not published). No contract's accept/reject behaviour moves and no public surface widens.

The hot file is finally free — and the wait is itself this card's evidence. It has been held since 2026-09-06T15:08Z (deferral 5560126920): first by PR #16215 (merged 06:15:26Z), then, with a two-minute overlap and no gap this seat could take, by PR #16511 (opened 06:13:25Z, merged 07:01:02Z; recorded 5566064480). Re-read at 08:02Z across all 21 open PRs: no PR touches content/docs/permissions/system-context.mdx or scripts/check-system-context-census.mjs. The card is titled "re-conflicts faster than one verification round" and it has now demonstrated that twice while waiting to be fixed.

Pre-dispatch premise checks at this claim (read on origin/main, not on the card):

The anchor count has drifted twice. Ruling A says "45 sources"; the deferral note measured 95 anchors over 60 files at 15:04Z yesterday; origin/main right now carries 83 line anchors of the form path:NNN over 61 distinct files. The dev re-derives its own number before starting and the PR body carries it — ⛔ no count from this thread is to be trusted as current.
The resolver to reuse is the one behind scripts/check-adr-symbol-anchors.mjs (the [finding] ADR line anchors into sql-driver.ts have rotted — 4 of 4 sampled resolve to unrelated code, and the ADRs read as if they still point at the mechanism they name #13556 ADR migration already enforces path#symbol under docs/adr/**), per the ruling.
The deferral's recorded pitfalls stand and are in the brief: the census population half must survive untouched, --fix must stop rewriting line numbers, and Two census-page row N references are declared unheld, so a row insertion can still silently falsify them — the residual #15869 left behind #15927's two unheld row references share that --fix leg.

The assignee and this comment are the PM's write. The dev inherits both, posts no second claim, and never touches the assignee field.

Claim: PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, 2026-09-07T11:04Z — re-dispatch under ruling B on the same branch claude/issue-15921-system-context-symbol-anchors. Supersedes the release 5567528582.

Clause-②: no

Reason for no: unchanged from the first dispatch — a docs page's anchor spelling plus the gate script that derives it. Ruling A already stated this is not a spec surface and that skip-changeset applies, and ruling B does not move that. (It also means the currently-exhausted contract-review tier does not block this card.)

Ruling B is in hand (5567940532, director seat, decision batch #77, maintainer 「其他同意」). The seat's recommendation was adopted: direction stands, the population half is amended to what the measured tree can actually satisfy. The dev that stopped here was right to stop — its measurement is what changed the ruling.

The hot-file re-check the ruling demanded, done before this claim, ⛔ not assumed: read at 11:02Z across all 18 open PRs — nothing touches content/docs/permissions/system-context.mdx or scripts/check-system-context-census.mjs. That page went from PR #16215 to PR #16511 with a two-minute overlap earlier today, so this window is not to be trusted to last; the dispatch says so.

Branch continuity: GET /branches/claude%2Fissue-15921-system-context-symbol-anchors ⇒ exists at 78e8485d6 (a per-branch existence check, ⛔ not the truncated listing that produced a wrong brief earlier today — see #16566). The predecessor pushed it empty; the successor continues on it rather than opening a second branch.

A fourth reading of the same count, because it keeps moving: ruling A said "45 sources"; a note yesterday measured 95 anchors / 60 files; this seat measured 83 / 61 at 08:02Z; origin/main now gives 94 distinct path:NNN anchors over 61 files. ⇒ the dev derives its own with the repo's own extractor and states it in the PR body. ⛔ No count from this thread is current.

The assignee and this comment are the PM's write. The dev inherits both, posts no second claim, and never touches the assignee field.

  "summary": "Migrated `content/docs/permissions/system-context.mdx` off `path:line` anchors onto `path#symbol`, and re-cut `scripts/check-system-context-census.mjs` around that. RESOLUTION is delegated whole to the shared resolver via a thin `defineCorpus` registration plus one `sweepCorpus` call — `scripts/symbol-anchors.mjs` is untouched by the diff, so option A's span-aware widening stays a separate card. POPULATION is now per file at symbol granularity: every file the census finds a read in carries an anchor, and the SET of symbols the page cites into that file equals the set the census plus `NON_READ_ANCHORS` require. `--fix` writes nothing and says so instead of exiting 0 in silence, so `gen:system-context-census` and `regen-artifacts.mjs` stay wired. `NON_READ_ANCHORS` is re-keyed from `needle` to `{file, symbol}` (27 rows -> 22), with a new declared `collapsesOntoRead` flag held to the census in both directions for the 7 rows whose symbol is also a census read symbol. `scripts/isystem-census.mjs` gained the enclosing-symbol derivation (outermost function-like named scope, accepted only when the SHARED resolver would resolve it) and `symbolPopulation()`. The precision loss the ruling names is written on the page itself in two places — the top Callout and 'What CI holds' — and both of its numbers are newly ENFORCED via `DECLARED_COUNTS`, so the sentence that prices the loss cannot go stale in either direction. MECHANISM ASSUMPTIONS: (1) every count in the thread was stale and was re-derived here with the repo's own instruments — see `tests`; (2) the 9-collision-file measurement HOLDS on this tree, same nine files as the predecessor reported; (3) the resolver behind `check-adr-symbol-anchors` was reusable for resolution unchanged, and the population half was written census-side, which is exactly the split the ruling encodes. FILE-LEVEL FALLBACK LIST — exactly one, and it is honest rather than a shortfall: `packages/plugins/plugin-auth/src/last-admin-guard.ts`, whose cited claim lives in the module docblock, which no declaration encloses. The census itself produces ZERO sites with no nameable symbol, so no elevation read needed a file-level anchor; the gate still carries a named refusal (`[site-without-a-file-anchor]`) for the first one that arrives. REQUIRED ANSWER, #15927 (ruling item 5), re-confirmed AFTER the change rather than before it: UNAFFECTED. #15927 is about the two `PAGE_ROW_REFERENCES` entries declared `unheld`; `PAGE_ROW_REFERENCES`, `checkRowReferences`, `extractRowReferences` and `extractTableRows` are unchanged in this diff, both `unheld` entries still locate their line (`2 declared unheld` in the gate's OK line), and neither of the two sentences is edited. The `--fix` leg #15927 names is the PROSE-renumbering leg, which never existed and still does not; the leg this PR deletes is the ANCHOR line-number rewriter, a different program. One number moved and it is not #15927's: `held.why` 9 -> 8, because two `engine.ts` ledger rows collapsed onto `#buildDriverOptions` and were merged into one row carrying one `row 23` mention; `held.page` stays 10 and `held.unheld` stays 2, and the self-test pin was updated in the same commit. #15927 also remains blocked on its own hold condition and this PR is one more open PR touching the page.",

ACCEPT — PR #16614 (head 6db543595, read 2026-09-07T12:36Z) — PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8. Reviewed against the three-dot diff origin/main...claude/issue-15921-system-context-symbol-anchors (3 files, +1072/−819).

Ruling B implemented, item by item, each verified here rather than taken from the report:

Resolution delegated, resolver untouched — git diff --name-only origin/main...<branch> contains no scripts/symbol-anchors.mjs. Registration is a defineCorpus + one sweepCorpus call. ⇒ option A's span-aware widening stays a separate card, as item 4 requires.
Population is per file, census-side — which is the split the ruling encodes and the predecessor's measurement predicted.
The precision loss is on the page a reader meets, not only in the PR body — and in both places the ruling asked for: the top Callout ("deleting a whole symbol reds this page, and deleting one of several reads inside a symbol that keeps at least one may not") and "Maintaining this table", which prices it with the measured 9-of-45 and names what closing it would take. Both of its numbers are now enforced through DECLARED_COUNTS, so the sentence pricing the loss cannot go stale in either direction — that is better than the ruling asked for.
The page is genuinely off line numbers: path:NNN anchors on the branch = 0 (was 141 occurrences), symbol anchors = 83 plus 8 file-level citations.

The ruled red-first pair, and a third run that makes it a measurement rather than an assertion. (a) a pure 40-line insertion above the anchored symbol ⇒ gate exit 0; (b) renaming getReadFilter ⇒ exit 1 with three independent findings from three checks; (c) the before-control — the base page and base scripts in the same tree under the same 40-line insertion ⇒ exit 1 with 28 findings. Same tree, same mutation, opposite verdicts. Every mutation was proven on disk before the gate was read and every restore proven by blob-hash equality plus an empty git diff HEAD, under a trap. ⭐ (c) is the reading that makes (a) meaningful: without it, "not red" could just mean a gate that never reds.

#15927, re-confirmed after the change as required, and honestly: UNAFFECTED — PAGE_ROW_REFERENCES, checkRowReferences, extractRowReferences, extractTableRows are unchanged, both unheld entries still locate their line, and the --fix leg #15927 names is the prose-renumbering leg, which never existed; the leg this PR deletes is the anchor line-number rewriter, a different program. The dev also surfaced the one number that did move and is not #15927's: held.why 9 → 8, because two engine.ts ledger rows collapsed onto one symbol, with the self-test pin updated in the same commit. Reporting a moved number nobody asked about is the behaviour that makes the rest of the report credible.

Open question 2 — the ruling's own wording is internally unsatisfiable, and this seat accepts the dev's reading. Item 2 says the page's distinct symbol anchors for a file must equal "the census's SITE count for that file". Checked arithmetically: the census finds 106 sites living in 89 distinct symbols, so sites exceed symbols, and on precisely the 9 collision files item 3 names, a distinct-symbol count can never equal a site count without span awareness — which is option A, deferred by item 4 of the same ruling. ⇒ the literal reading contradicts the ruling's own rationale; the shipped reading (per-file set equality over symbols, both counts printed in every refusal) is the only one consistent with the ruling as a whole, and it is strictly more useful than a count, since it can name the missing symbol. ⛔ This seat is not re-ruling: it is implementing the intent and recording the interpretation for the director seat to confirm or correct on the ruling thread. If corrected, the dev says the change is one block in evaluate.

Open question 1 (skip-changeset) — resolved as A, applied by this seat just now, the same conflict this seat created earlier today and the same resolution: the dispatch reserved the label, so the dispatch applies it. ⚠️ Check Changeset is currently red because it ran before the label existed; that job reads labels live, so the flip point reruns it rather than treating it as a defect (established tonight on PR #16371).

Verification: 62 dispatch-gates families derived, 62 run, 0 NOT-MEASURED — four first answered PREREQUISITE NOT MET on unbuilt packages and one hit a 600 s wrapper timeout, all read as not measured rather than as red, then passed. Repo-wide eslint 6291 files, 0 errors. turbo ls --affected = 0 packages, correctly so for a scripts/** + content/docs/** diff. The os-regen merge driver was exercised through scripts/pm/os-regen-merge.sh and kept the branch's bytes; check-regen-pending clean.

Out of scope, well judged: #16612 — once this page carries no line numbers, the os-regen mixed: 'line-anchors' comparator becomes the identity (measured: base 141 anchors, not identity; branch 0 anchors, is identity), so the routing's safety argument and three prose blocks go stale together. Filed rather than repaired, because the dispatch fenced the merge driver off by name.

Landing plan: flip point armed 13:15Z. First action there is rerun_failed_jobs on Check Changeset, then flip when every row at 6db543595 reads completed/success on its own line → auto-merge → probe added_to_merge_queue. ⚠️ Expect an os-regen lap on any main move. On MERGED → probe on origin/main: path:NNN anchors in content/docs/permissions/system-context.mdx = 0, deleting one of several reads inside a symbol ≥1 (the precision note survived), and node scripts/check-system-context-census.mjs exits 0; negative control: the same path:NNN pattern = 141 at the pre-merge ref (the zero is real).

Generated by Claude Code

Correction to the landing plan's negative control, before it becomes a probe that fails (PM seat, 12:40Z). The ACCEPT above specifies the control as "the same path:NNN pattern = 141 at the pre-merge ref". 141 is the dev's extractor's occurrence count (96 full + 42 continuation + 3 range-end), not the count of the crude grep -c -E '[A-Za-z0-9_./-]+\.(ts|mjs|tsx):[0-9]+' the probe line actually names — which reads 83 at the pre-merge ref abb140c60, measured just now.

Corrected probe for the merged-state check:

on origin/main after merge: that pattern in content/docs/permissions/system-context.mdx = 0
negative control at abb140c60 (pre-merge): the same pattern = 83 — a live control proving the zero is a real change and not a broken pattern
deleting one of several reads inside a symbol ≥ 1 (the precision note survived)
node scripts/check-system-context-census.mjs exits 0 on the merged tree

Everything else in the ACCEPT stands. Mixing two instruments' counts is the same class of error this card exists to fix, so it is corrected here rather than left for the probe to trip over.

Third live instance of this card's own thesis, recorded while fixing it (PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, 12:59Z).

PR #16614 was flipped ready at 12:57:56Z with all 31 distinct checks green, auto-merge armed 12:58:00Z — and by 12:58:58Z it read mergeable: false, mergeable_state: dirty. Cause: PR #16587 landed on main and touched the files this card owns, inside the ~20 minutes between the dev finishing and this seat flipping. git merge-tree against the merge base confirms a real conflict, not a transient state.

So the count of times this page has re-conflicted faster than one verification round, today alone:

PR feat(organizations): bring the multi-organization runtime back to open core — the org-scoping registrar ships open, the licence gate stays in cloud (ADR-0132) #16215 → PR fix(rest): name the conjunct that actually failed in OBJECT_API_METHOD_NOT_ALLOWED #16511 with a two-minute overlap, which is why this card waited from 2026-09-06T15:08Z (5566064480).
The window this seat took at 11:02Z to re-dispatch under ruling B.
This one — conflicted between the dev's last push and the flip, while the fix for the problem was itself in review.

⭐ That is the finding demonstrating itself against its own repair, which is worth more than the argument the card originally made. It is also the honest measure of what ruling B buys: after this lands, a pure line move on an anchored source will not rot the page at all — instance 3's class disappears, even though ordinary content conflicts on the page remain possible.

Handled as an ordinary regen lap: the dev is back on the same branch and same claim to merge origin/main through scripts/pm/os-regen-merge.sh and push. Auto-merge stays armed and fires on its own once the branch is clean and green — ⛔ this seat neither resolves the conflict itself (that is dev work, not PM work) nor re-flips anything. If #16587 turns out to have changed what the census measures rather than only where lines sit, the dev stops and reports instead of hand-resolving.

  "premise_still_valid": true,
  "summary": "Migrated `content/docs/permissions/system-context.mdx` off `path:line` anchors onto `path#symbol`, and re-cut `scripts/check-system-context-census.mjs` around that. RESOLUTION is delegated whole to the shared resolver via a thin `defineCorpus` registration plus one `sweepCorpus` call — `scripts/symbol-anchors.mjs` is untouched by the diff, so option A's span-aware widening stays a separate card. POPULATION is now per file at symbol granularity: every file the census finds a read in carries an anchor, and the SET of symbols the page cites into that file equals the set the census plus `NON_READ_ANCHORS` require. `--fix` writes nothing and says so instead of exiting 0 in silence, so `gen:system-context-census` and `regen-artifacts.mjs` stay wired. `NON_READ_ANCHORS` is re-keyed from `needle` to `{file, symbol}` (27 rows -> 22), with a new declared `collapsesOntoRead` flag held to the census in both directions for the 7 rows whose symbol is also a census read symbol. `scripts/isystem-census.mjs` gained the enclosing-symbol derivation (outermost function-like named scope, accepted only when the SHARED resolver would resolve it) and `symbolPopulation()`. The precision loss the ruling names is written on the page itself in two places — the top Callout and 'What CI holds' — and both of its numbers are newly ENFORCED via `DECLARED_COUNTS`, so the sentence that prices the loss cannot go stale in either direction. MECHANISM ASSUMPTIONS: (1) every count in the thread was stale and was re-derived here with the repo's own instruments — see `tests`; (2) the 9-collision-file measurement HOLDS on this tree, same nine files as the predecessor reported; (3) the resolver behind `check-adr-symbol-anchors` was reusable for resolution unchanged, and the population half was written census-side, which is exactly the split the ruling encodes. FILE-LEVEL FALLBACK LIST — exactly one, and it is honest rather than a shortfall: `packages/plugins/plugin-auth/src/last-admin-guard.ts`, whose cited claim lives in the module docblock, which no declaration encloses. The census itself produces ZERO sites with no nameable symbol, so no elevation read needed a file-level anchor; the gate still carries a named refusal (`[site-without-a-file-anchor]`) for the first one that arrives. REQUIRED ANSWER, #15927 (ruling item 5), re-confirmed AFTER the change rather than before it: UNAFFECTED. #15927 is about the two `PAGE_ROW_REFERENCES` entries declared `unheld`; `PAGE_ROW_REFERENCES`, `checkRowReferences`, `extractRowReferences` and `extractTableRows` are unchanged in this diff, both `unheld` entries still locate their line (`2 declared unheld` in the gate's OK line), and neither of the two sentences is edited. The `--fix` leg #15927 names is the PROSE-renumbering leg, which never existed and still does not; the leg this PR deletes is the ANCHOR line-number rewriter, a different program. One number moved and it is not #15927's: `held.why` 9 -> 8, because two `engine.ts` ledger rows collapsed onto `#buildDriverOptions` and were merged into one row carrying one `row 23` mention; `held.page` stays 10 and `held.unheld` stays 2, and the self-test pin was updated in the same commit. #15927 also remains blocked on its own hold condition and this PR is one more open PR touching the page. LAP 2 (os-regen, merged origin/main 68437d4d95, head a3b057a9c8): the conflict was PR #16587, whose only touch to this card's files was two rows of the page, both PURE line-number re-anchorings of `domains/automation.ts` written by the OLD `--fix`. Proved with the repo's own comparator that main's page change is entirely the generated half — `blankAnchorLineNumbers(main) === blankAnchorLineNumbers(merge-base)` is true while the raw bytes differ — so keeping the branch's bytes loses nothing. `os-regen-merge.sh` step 2 correctly reported 'both sides changed it' and took main's side into the worktree; its own runbook covers this case ('if the branch's edit here was a HAND edit that no regeneration reproduces, restore the branch bytes before regenerating'), which is exactly this branch, because `--fix` no longer regenerates anything. #16587 CHANGED NOTHING THE CENSUS MEASURES: 106 sites / 20 packages / 45 files / 89 symbols / 9 collapsing files, all identical; `domains/automation.ts` still holds 4 reads in the same 4 symbols (mayReadRunState, refuseUngrantedFlowWrite, refuseUnrelatedScreenRead, handleAutomationRequest), moved from lines 254/545/635/989 to 255/546/636/1079. No page edit was needed and none was made; the gate is green with zero findings. ⚠️ THE LAP EXPOSED A REAL DEFECT IN MY OWN LAP-1 WORK, now fixed in a3b057a9c8: the new red-first self-test battery built its throwaway git corpus with the AMBIENT environment, so under `pre-commit` (where `check-regen-pending` invokes this gate, and where an os-regen lap lands) the exported GIT_DIR / GIT_WORK_TREE / GIT_INDEX_FILE were inherited: `git init` created nothing and `git add -A` wrote THE REPOSITORY'S index — 8,190 paths staged as deleted — while every self-test case still printed ok. Recovered with `git reset --hard` onto the merge commit, which already held the correct tree; damage was confined to this worktree's own index (the index is per-worktree), no other worktree and no commit was affected. The fix strips every GIT_* key for the duration of the self-test, passes the stripped environment to each child explicitly, and adds a regression pin that injects a bogus GIT_DIR and requires the throwaway tree to come back with its own two files staged. Residual, stated rather than widened: `sweepCorpus` resolves through `git ls-files` and passes no environment of its own, so a sweep of a SYNTHETIC root inherits the caller's GIT_DIR — every in-repo caller is unaffected, and hardening the shared resolver is forbidden by the ruling, so the caveat is recorded beside the CORPUS registration instead.",

  "premise_still_valid": true,
  "summary": "Migrated `content/docs/permissions/system-context.mdx` off `path:line` anchors onto `path#symbol`, and re-cut `scripts/check-system-context-census.mjs` around that. RESOLUTION is delegated whole to the shared resolver via a thin `defineCorpus` registration plus one `sweepCorpus` call — `scripts/symbol-anchors.mjs` is untouched by the diff, so option A's span-aware widening stays a separate card. POPULATION is now per file at symbol granularity: every file the census finds a read in carries an anchor, and the SET of symbols the page cites into that file equals the set the census plus `NON_READ_ANCHORS` require. `--fix` writes nothing and says so instead of exiting 0 in silence, so `gen:system-context-census` and `regen-artifacts.mjs` stay wired. `NON_READ_ANCHORS` is re-keyed from `needle` to `{file, symbol}` (27 rows -> 22), with a new declared `collapsesOntoRead` flag held to the census in both directions for the 7 rows whose symbol is also a census read symbol. `scripts/isystem-census.mjs` gained the enclosing-symbol derivation (outermost function-like named scope, accepted only when the SHARED resolver would resolve it) and `symbolPopulation()`. The precision loss the ruling names is written on the page itself in two places — the top Callout and 'What CI holds' — and both of its numbers are newly ENFORCED via `DECLARED_COUNTS`, so the sentence that prices the loss cannot go stale in either direction. MECHANISM ASSUMPTIONS: (1) every count in the thread was stale and was re-derived here with the repo's own instruments — see `tests`; (2) the 9-collision-file measurement HOLDS on this tree, same nine files as the predecessor reported; (3) the resolver behind `check-adr-symbol-anchors` was reusable for resolution unchanged, and the population half was written census-side, which is exactly the split the ruling encodes. FILE-LEVEL FALLBACK LIST — exactly one, and it is honest rather than a shortfall: `packages/plugins/plugin-auth/src/last-admin-guard.ts`, whose cited claim lives in the module docblock, which no declaration encloses. The census itself produces ZERO sites with no nameable symbol, so no elevation read needed a file-level anchor; the gate still carries a named refusal (`[site-without-a-file-anchor]`) for the first one that arrives. REQUIRED ANSWER, #15927 (ruling item 5), re-confirmed AFTER the change rather than before it: UNAFFECTED. #15927 is about the two `PAGE_ROW_REFERENCES` entries declared `unheld`; `PAGE_ROW_REFERENCES`, `checkRowReferences`, `extractRowReferences` and `extractTableRows` are unchanged in this diff, both `unheld` entries still locate their line (`2 declared unheld` in the gate's OK line), and neither of the two sentences is edited. The `--fix` leg #15927 names is the PROSE-renumbering leg, which never existed and still does not; the leg this PR deletes is the ANCHOR line-number rewriter, a different program. One number moved and it is not #15927's: `held.why` 9 -> 8, because two `engine.ts` ledger rows collapsed onto `#buildDriverOptions` and were merged into one row carrying one `row 23` mention; `held.page` stays 10 and `held.unheld` stays 2, and the self-test pin was updated in the same commit. #15927 also remains blocked on its own hold condition and this PR is one more open PR touching the page. LAP 2 (os-regen, merged origin/main 68437d4d95, head a3b057a9c8): the conflict was PR #16587, whose only touch to this card's files was two rows of the page, both PURE line-number re-anchorings of `domains/automation.ts` written by the OLD `--fix`. Proved with the repo's own comparator that main's page change is entirely the generated half — `blankAnchorLineNumbers(main) === blankAnchorLineNumbers(merge-base)` is true while the raw bytes differ — so keeping the branch's bytes loses nothing. `os-regen-merge.sh` step 2 correctly reported 'both sides changed it' and took main's side into the worktree; its own runbook covers this case ('if the branch's edit here was a HAND edit that no regeneration reproduces, restore the branch bytes before regenerating'), which is exactly this branch, because `--fix` no longer regenerates anything. #16587 CHANGED NOTHING THE CENSUS MEASURES: 106 sites / 20 packages / 45 files / 89 symbols / 9 collapsing files, all identical; `domains/automation.ts` still holds 4 reads in the same 4 symbols (mayReadRunState, refuseUngrantedFlowWrite, refuseUnrelatedScreenRead, handleAutomationRequest), moved from lines 254/545/635/989 to 255/546/636/1079. No page edit was needed and none was made; the gate is green with zero findings. ⚠️ THE LAP EXPOSED A REAL DEFECT IN MY OWN LAP-1 WORK, now fixed in a3b057a9c8: the new red-first self-test battery built its throwaway git corpus with the AMBIENT environment, so under `pre-commit` (where `check-regen-pending` invokes this gate, and where an os-regen lap lands) the exported GIT_DIR / GIT_WORK_TREE / GIT_INDEX_FILE were inherited: `git init` created nothing and `git add -A` wrote THE REPOSITORY'S index — 8,190 paths staged as deleted — while every self-test case still printed ok. Recovered with `git reset --hard` onto the merge commit, which already held the correct tree; damage was confined to this worktree's own index (the index is per-worktree), no other worktree and no commit was affected. The fix strips every GIT_* key for the duration of the self-test, passes the stripped environment to each child explicitly, and adds a regression pin that injects a bogus GIT_DIR and requires the throwaway tree to come back with its own two files staged. Residual, stated rather than widened: `sweepCorpus` resolves through `git ls-files` and passes no environment of its own, so a sweep of a SYNTHETIC root inherits the caller's GIT_DIR — every in-repo caller is unaffected, and hardening the shared resolver is forbidden by the ruling, so the caveat is recorded beside the CORPUS registration instead. ⚠️ ADDENDUM — the env leak had a SECOND, worse symptom on SHARED state, found and repaired after the first lap-2 report: `git init` running with the inherited GIT_DIR and a cwd outside any work tree also wrote `core.bare = true` into the SHARED `.git/config`, which every worktree reads. The primary checkout at /home/user/objectstack was left answering 'fatal: this operation must be run in a work tree' and `git worktree list` reported it as `(bare)`, for every agent on this box. Repaired with `git config core.bare false`; verified afterwards that the primary checkout is back (HEAD claude/pm-dispatch-devx-956ft5 at 33388f9db9 — unchanged from session start, clean tree), that `core.hooksPath` and the `merge.os-regen.driver` entry survived, that all branch and remote refs are intact, and that both sibling worktrees (issue-15776b, issue-15915) still resolve their HEAD with a clean status. ⛔ No file in the primary checkout was ever edited; the damage was one config key and it was mine. The fix already committed in a3b057a9c8 closes this too — `git init` now receives no GIT_DIR at all — and the regression pin exercises exactly that call under an injected bogus GIT_DIR.",
  "tests": "MEASUREMENTS (own, with the repo's own extractors; every figure in the card thread was stale). Page at merge base f2f6684cd5 via `doc-line-anchors.mjs#extractLineAnchors`: 141 anchor occurrences (96 full + 42 continuation + 3 range-end), 61 distinct spellings, 57 resolved files, 133 distinct file:line targets, 7 path citations with no line (5 distinct).

RULED RED-FIRST PAIR, on the real tree, implementation committed first, each mutation proved on disk before the gate was read and each restore proved by `git diff HEAD` plus a blob-hash comparison against the HEAD blob (script carried `trap restore EXIT INT TERM` with absolute paths). (a) PURE LINE MOVE must NOT red: 40 lines inserted above `packages/objectql/src/engine.ts` — on-disk proof '// ablation padding' lines 0 -> 40, blob 1cead9fce99e -> b918910be42c; gate exit 0; restored, `git diff HEAD` empty, hash 1cead9fce99e == HEAD blob 1cead9fce99e. (b) SYMBOL RENAME must RED: `getReadFilter` -> `getReadFilterRenamedForAblation` in `security-plugin.ts` — on-disk proof old spelling 20 -> 0, new spelling 0 -> 20; gate exit 1 with THREE findings from three different checks: `[unresolved-symbol] ...#getReadFilter`, `[site-without-a-row] ...#getReadFilterRenamedForAblation holds 1 elevation read(s)`, `[anchor-is-not-a-read-site] the page anchors ...#getReadFilter`; restored, `git diff HEAD` empty, hash 84ae26d2d588 == HEAD blob 84ae26d2d588. (c) BEFORE-CONTROL, so the property is measured and not asserted: base page + base scripts checked out into the SAME tree, the SAME 40-line insertion applied — base gate exit 1 with 28 findings ('[site-without-a-row] packages/objectql/src/engine.ts:10455 / :11807 / :11990 ...'), against exit 0 on this branch. Same tree, same mutation, opposite verdicts. Restored to a clean `git status`. The pair is ALSO pinned inside `--self-test` as its own battery, driving the real `sweepCorpus` over a throwaway `git init` corpus (control clean / rename red / 40-line pad still clean). DISPATCH-GATES: `node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack` derived 62 families; all 62 run; `--ran` verdict '62 derived famil(ies) accounted for — 62 run, 0 NOT-MEASURED.' Four first answered PREREQUISITE NOT MET (exit 3 / unbuilt @objectstack/lint, formula, client-react) — read as NOT MEASURED, not as red — then passed after building those packages; `check:pm-dispatch-gates` first hit a 600s timeout (exit 124, also not a red) and passed at 1534 self-test cases with a longer budget. The family list was re-derived after merging origin/main and is byte-identical. LINT: not narrowed — the full repo-wide set ran and there was nothing to narrow. `pnpm exec eslint . --no-inline-config --format json` at `6db5435952` (the final head): 6291 files, 0 errors, 0 warnings. AFFECTED PACKAGES: `turbo ls --affected` with TURBO_SCM_BASE set to the merge base reports 0 packages — the diff is `scripts/**` and `content/docs/**` only, so no package test or typecheck is owed. MERGE: origin/main merged through `scripts/pm/os-regen-merge.sh` (step 2 correctly KEPT the branch's bytes of the page — branch changed it, main did not); `check-regen-pending` clean, no deferral outstanding; gate and self-test re-run green on the merged head. BYTE HYGIENE: `pnpm check:nul-bytes` green, plus a manual `grep -naP '[\\x00-\\x08\\x0b\\x0c\\x0e-\\x1f\\x7f]'` over all three changed files — no hits. LAP 2, at head a3b057a9c8 (base 68437d4d95). Merge taken through `scripts/pm/os-regen-merge.sh`; step 3's commit was refused by pre-commit, which is that sequence's designed collection point. Post-merge: `node scripts/isystem-census.mjs` 106 sites / 20 packages / 45 files; `node scripts/check-system-context-census.mjs` exit 0 with the SAME OK line as lap 1 and zero findings; `--self-test` exit 0, 74 cases across 18 batteries (one new: the GIT_* env-leak regression pin). REGRESSION PROOF for the env leak, taken through the very path that broke: the commit carrying the fix ran `pre-commit`, the hook ran this gate and its self-test, the os-regen marker printed 'content/docs/permissions/system-context.mdx — current ... marker cleared', and `git status --porcelain` afterwards is EMPTY (it was 8,190 staged deletions before the fix). Gate families re-derived at the new head: 62, byte-identical to lap 1; all 62 re-run; `--ran` verdict '62 derived famil(ies) accounted for — 62 run, 0 NOT-MEASURED' — this lap with zero PREREQUISITE NOT MET results, because the four packages were pre-built. `pnpm exec eslint . --no-inline-config --format json` at a3b057a9c8: 6293 files, 0 errors, 0 warnings. MERGEABILITY: the driver-free probe the runbook prescribes (bare shared clone, no custom driver — the only instrument that tracks GitHub's condition) exits 0; GitHub now reports `mergeable: true, mergeable_state: blocked`, i.e. the conflict is gone and only required checks remain, which is the PM's and the queue's business. The PR reads `draft: false` — flipped and armed by the PM seat, ⛔ untouched here. SHARED-STATE REPAIR, verified: `git config --get core.bare` -> false; `git rev-parse --abbrev-ref HEAD` in the primary checkout -> claude/pm-dispatch-devx-956ft5 (33388f9db9, unchanged); `git status --porcelain` -> 0 entries; `git worktree list` lists the primary checkout with its branch again instead of `(bare)`; `core.hooksPath` -> .githooks and `merge.os-regen.driver` -> the git-merge-regen.mjs invocation, both intact; sibling worktrees issue-15776b and issue-15915 both resolve HEAD with 0 dirty entries.",

        "A — the PM applies it (what this seat did: no label written, no changeset added, the reasoning stated in the PR body)",

        "A — accept the shipped reading: per-file SET equality over symbols, counts reported in the refusal text (what landed)",

ACCEPT (lap 2) — PR #16614 at head a3b057a9c, read 2026-09-07T13:35Z — PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8. The lap-1 ACCEPT (5570751542) stands; this covers the os-regen lap and what it turned up.

Queue state: mergeable: true, mergeable_state: clean, 31 distinct checks green (deduped latest-per-name — a raw list still carries the superseded Check Changeset failure), added_to_merge_queue 13:32:05Z. The conflict is gone.

The conflict was benign and the dev proved it rather than asserting it. PR #16587's only touch to this card's files was two page rows, both pure line-number re-anchorings written by the OLD --fix. It demonstrated that with the repo's own comparator — blankAnchorLineNumbers(main) === blankAnchorLineNumbers(merge-base) is true while the raw bytes differ — so keeping the branch's bytes loses nothing, and os-regen-merge.sh's own runbook covers exactly this case (a hand edit no regeneration reproduces, which is what this branch is now that --fix regenerates nothing). The census is unmoved: 106 sites / 20 packages / 45 files / 89 symbols / 9 collapsing files, identical to lap 1; domains/automation.ts still holds 4 reads in the same 4 symbols, only their lines moved. ⇒ #16587 changed nothing the census measures, so no page edit was owed and none was made. That is the outcome ruling B was designed to produce, observed on its first real collision.

⚠️ The lap exposed a defect in the dev's own lap-1 work, and it damaged shared state. The new red-first self-test built its throwaway git corpus with the ambient environment. Under pre-commit — where check-regen-pending invokes this gate, and where an os-regen lap lands — the inherited GIT_DIR / GIT_WORK_TREE / GIT_INDEX_FILE meant git init created nothing and git add -A wrote the repository's index: 8,190 paths staged as deleted, while every self-test case still printed ok. Worse, git init with an inherited GIT_DIR and a cwd outside any work tree also wrote core.bare = true into the shared .git/config, which every worktree on this box reads — leaving the primary checkout answering "fatal: this operation must be run in a work tree" for every agent here, not just this one.

Repaired, and verified by this seat independently rather than taken on trust (13:34Z, read directly in /home/user/objectstack): core.bare → false; HEAD → claude/pm-dispatch-devx-956ft5 at 33388f9db, unchanged from session start; git status --porcelain → 0 entries; git ls-files → 7947 tracked (not 8,190 deletions); git worktree list shows the primary checkout with its branch again, not (bare); core.hooksPath = .githooks and merge.os-regen.driver both survived; the two sibling worktrees (issue-15776b, issue-15915, other agents' work) resolve HEAD clean. ⛔ No file in the primary checkout was ever edited — the damage was one config key.

The fix is in the diff, not just in prose: the self-test now strips every GIT_* key and passes the stripped environment to each child explicitly, plus a regression pin that injects a bogus GIT_DIR and requires the throwaway tree to come back with its own two files staged. The proof runs through the path that broke — the commit carrying the fix went through pre-commit, which ran this gate and its self-test, and git status --porcelain afterwards is empty. 62 gate families re-derived at the new head (byte-identical to lap 1), all 62 run, 0 NOT-MEASURED, this lap with zero PREREQUISITE NOT MET. Repo-wide eslint 6293 files, 0 errors.

⭐ Recorded plainly because it is the behaviour worth having: this dev broke shared infrastructure, found it itself, fixed it, repaired the shared state, and disclosed the whole sequence including the part nobody would have traced back to it. A silent core.bare = true would have cost every agent on this box hours of confusion. ⛔ It is not counted against the dev; the disclosure is the reason the repair happened at all.

Open question 3 — the residual, and this seat's answer: file it. sweepCorpus / trackedFiles in scripts/symbol-anchors.mjs resolve through git ls-files and pass no environment of their own, so a sweep of a synthetic root still inherits the caller's GIT_DIR. Every in-repo caller is unaffected, and ruling B forbids this card from widening that file — correctly contained here, with the incident written into buildRedFirstCorpus's header. But the next corpus's tests can repeat this, so it goes out as its own card rather than living only in a comment.

Landing plan unchanged from the lap-1 ACCEPT and its probe correction (5570755054): on MERGED, probe origin/main for 0 path:NNN anchors against the 83 live control at abb140c60, the precision note surviving, and check-system-context-census.mjs exiting 0.

LANDED — PR #16614 merged 2026-09-07T13:52:31Z (merge commit 55bbd92e3, head a3b057a9c, Fixes #15921 closed the card). PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, probe read 2026-09-07T14:10Z.

Ruling B implemented (5567940532, director seat, decision batch #77, maintainer 「其他同意」), per the two ACCEPTs 5570751542 (lap 1) and 5571454152 (the os-regen lap).

Queue: added_to_merge_queue 13:32:05Z, merged 13:52:31Z, zero regroups, no removal, the seat's one re-queue unspent. All four group workflows green (CI, Lint & Type Check, Spec Liveness Check, Governed Surface Guard) — ⚠️ the CI run alone finished 13 minutes before the group did, so "CI is green" was never the same statement as "the group is green".

Content probe on origin/main = 55bbd92e3 (git fetch + git merge-base --is-ancestor yes), in content/docs/permissions/system-context.mdx:

reading	result	expected
(a) `path:NNN` line anchors	0	0
(b) live control — same pattern at pre-merge `abb140c60`	83	≥1, proving the zero is a real change and not a broken pattern
(c) the ruled precision note (`deleting one of several reads inside a symbol`)	1	≥1
(d) `check-system-context-census.mjs` exits 0	NOT MEASURED	— see below

⚠️ (d) is NOT MEASURED from this seat, and that is not a pass. Run in the primary checkout the gate answered exit 3 — PREREQUISITE NOT MET: typescript is not installed on the resolution path from scripts/, which its own text is emphatic about: "Nothing was measured … this result says NOTHING about what it gates. It is NOT a finding." ⛔ So this seat does not report it as green. The evidence that exists is the dev's own run at the merged head — exit 0 with its full OK line (106 sites / 20 packages / 45 files / 89 symbols / 103 cited == 103 required / 127 anchors / 8 file-level / 22 declared non-read / 9 collapsing files / 18 row references, 2 declared unheld) — plus the same gate green inside CI's Lint & Repo Gates on the landing group. ⛔ This seat did not run pnpm install in a shared checkout to manufacture a reading.

⭐ The gate caught this seat's own method error first. The initial probe piped the gate into tail and read $? — which is the pipe's status, not the gate's, so it printed a false exit=0. The gate's own prerequisite text names exactly that trap ("capture it BEFORE any pipe … head/tail essentially never fail — that is the false green"). Re-run with > file 2>&1; code=$?, the true answer was 3. Third method error caught this shift, and the only one caught by the tooling rather than by a person.

Card: pm:dispatched stripped (four-step, read-back tooling, priority:p2, domain:devx, finding); assignee cleared; closed by GitHub via Fixes.

What this card actually proved, beyond its fix. Its thesis — that this page re-conflicts faster than one verification round — fired three times today, the last one against its own repair: (1) PR #16215 → PR #16511 with a two-minute overlap, which is why it waited from 2026-09-06T15:08Z; (2) the window this seat took at 11:02Z; (3) PR #16587 landing between the dev's last push and the flip (5571014904). After this merge, instance (3)'s class is gone: a pure line move in an anchored source can no longer rot the page. Ordinary content conflicts remain possible — the card fixed the rot, not the traffic.

Open items this landing does not close: the interpretation recorded for the director seat (ruling item 2's literal count-equality is arithmetically unsatisfiable — 106 sites in 89 symbols — so per-file set equality over symbols shipped instead; one block in evaluate if corrected); #16612 (the os-regen line-anchors comparator becomes the identity now that this page has no line numbers); and #16624 (the shared sweepCorpus still inherits a caller's GIT_DIR for synthetic roots — the residual of the incident this card's lap-2 exposed and repaired).
