[hotlong]

⚠️ This post is the RECORD of state, not the state. Every round, re-read the labels. ⛔ Never read the counts here as current.

📌 Job description is versioned at .claude/skills/pm-dispatch/references/lanes/engine.md. ⛔ Not hand-copied per term.

1. Current PM — 🟢 os-musk

• Session session_01RuoNSXUbBoWHkNS4AknTrM · R1 · seated 2026-09-10T23:3xZ via maintainer invocation /pm-dispatch engine.
• Mutual-exclusion readings at seating (all four, before the first write): ① R3's 收班简报 5623087745 @ 17:55:24Z is the newest seat event; ② no 开轮标记 after it; ③ no Claim: newer than the brief on any pm:dispatched/pm:queue card in this lane, and git ls-remote shows no branch for any queue card; ④ newest CLOSED lane card ([finding] driver-sql and both migration generators default an absent or unknown field type to DIFFERENT families — string versus text, so the unvalidated authoring door produces two different columns #16319) carries R3's own session. ⇒ Brief is the latest event ⇒ 立即坐席.
• Charter files (SKILL.md, core-rules.md, lanes/engine.md) all last touched by 06df3271cc @ 2026-09-10T15:24:50Z and byte-identical to origin/main in this checkout — no re-read owed.

Standing parameters: in-flight ceiling 3 (maintainer, 2026-09-09). ⭐ A clause-② dispatch needs no slot held back for a reviewer — #17294 made this lane's review in-seat.

⛔⛔ Tier: this seat reviews its own clause-② work, at default tier

SKILL.md:641 「余席默认档自审加门禁」 · contract-review.md:28 · :50 puts it outside the downgrade fuse. ⇒ ⭐ The path limb decides WHETHER a clause-② review is owed; :641 decides WHO and at what tier — this seat, default tier, plus the gates. ⚠️ A lifted TIER does not drop the needs:contract-review LABEL: the label marks that a review is owed, the tier decides who performs it.

2. Ledger — read at 2026-09-10T23:3xZ

origin/main = f721ef0ff2 at seating. ⛔ Re-fetch before any tree claim.

⚠️⚠️ R3's "ZERO dispatchable" is FALSIFIED on re-establishment — the lane holds ~21 queue cards

R3 signed off at 17:55Z reporting pm:queue = 2 and 「0 可派,逐卡建立」. Re-establishing card-by-card at seating, label:domain:engine state:open returns 61 cards of which ~21 carry pm:queue with no assignee, no needs-user-decision and no pm:retriage. Most were graded into this lane by the triage seat between 14:22Z and 15:21Z on 09-10 — i.e. while R3 held the seat.

⭐ This is exactly the failure the 「⛔ 零可派是一个结论,不是空转执照,下一任要逐卡重新建立」 rule exists to catch, and it caught it. ⛔ A lane read taken at the START of a shift is not a lane state at the END of one. R3 re-read its cards but not its lane.

Landed this round — 3, each verified by TWO readings

R1 dispatched 8, landed 8.

R1 dispatched 8, landed 8.

R1 dispatched 8, landed 8. Two needed a rework round; both reworks were the seat's diagnosis being wrong, ⛔ not the dev's work.

⭐ The scoreboard that matters more than 6/6

Four dispatch premises were falsified by measurement; three were this seat's.

card	what was falsified	who paid
#17501	seat ruled C; option A measured to weaken 24 types (required −265) ⇒ re-ruled D, blast radius 1	measured before any code
#16746	seat's suggested route changes nothing (app gate fires first); the only reachable combination opens 14 Setup entries	measured before any code
#17175	the card's own "logged at ERROR" — it is warn; that closed the ruling's shape (b) outright	one measurement
#17175	seat said the PG arm was pinnable on the live-dialect job — it is not, and the seat's own read-only fence closed the only door ⇒ #17621	one measurement
#17409	⭐ TRIAGE's premise, not the seat's: 「the gate that exists to catch the author certifies the thing that will crash」. ⛔ It does not — @objectstack/lint ships fieldRuleRootIssue + FIELD_RULE_BOUND_ROOTS (validate-expressions.ts:688/:790, exported at index.ts:53) which rejects data at all three field-rule slots, with a shipped test named for that case. SCOPE_ROOTS is a 「never faults」 baseline published so a per-surface gate can compute its COMPLEMENT (cel-engine.ts:88), ⛔ not an accept set	measured before any code; ⭐ and the seat's own Zone 3 was stale — the per-scope accept set it floated as a design idea had already shipped in #13935
#17586	seat's rework hypothesis (Postgres aggregate cast) — the real cause was the PR's own new assertion hitting json having no equality operator	one rework round, and the hypothesis got measured on the way out

⚠️ And the sharpest premise trap, found on #17584: a card's guidance can be stale in BOTH directions at once. Triage had correctly caught that the card's 「every boundary applies the bound」 was wider than the tree, and instructed 「⛔ you cannot reproduce a truncated 501」. By dispatch time #16146 had landed and the door read boundedDeclaredRefusalMessage ⇒ triage's own correction was stale and the reproduction WAS available. ⇒ ⛔ Re-measure both the card and its triage comment; a correction is not more current than the thing it corrected. The round's end-to-end red exists only because it did.

⚠️ And one ordering trap, found on #7898: it carries no priority:* label, so a label sort puts it last — while the total order puts it second only to p0, because pm:blocking is computed from the reverse Blocked-by: index (#17625 declares it; fan-out 1 over all 78 open pm:blocked cards). ⇒ ⛔ Never take the queue's priority column as the order. A ruled, security-boundary, downstream-blocking card sat at the bottom of it. Grading gap reported to triage, ⛔ not re-graded here.

⇒ ⭐ The lesson is not "the seat is unreliable"; it is that labelling an assumption as a reading rather than a measurement, and ordering the dev to falsify it, is what converts a wrong instruction into one cheap measurement instead of a wrong landing. Every one of the five above was caught that way.

✅ #17587 执行完毕 — the director ruling, and what the sweep it ordered turned up

Six writes, each read back by an independent second GET (⛔ not from the PATCH echo): #5499's body gained the criterion; #17446 · #17348 · #17301 · #17286 · #14082 each carry exactly one Restart-when: line, byte-identical (232 B) to #5499's, with the old 6-file proxy string gone and labels/state/footer-count unchanged. One audit comment per card. #17587 closed completed, pm:queue dropped.

⭐ #14082 is the interesting one: its criterion had lived only in a comment (R1's own half-state heal 5629831637, which said in as many words 「consistency now, one correction point later」). This was that correction point — the line now lives in the body and the comment's copy is declared void.

⭐⭐ The ruling's 「and any other hold citing #5499」 clause forced a repo-wide sweep, and it paid:

• Population closed: 104 open pm:on-hold cards repo-wide (two pages — ⛔ the first page returns exactly 100 and stopping there would have been a silent truncation), of which exactly 5 cite [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499 = the ruling's list. No sixth.
• ⚠️ driver-mongodb: bulkUpdate's single bulkWrite is only atomic when the caller supplies a session — a mid-batch refusal without one leaves earlier ops applied #14169 (driver-mongodb) sits inside [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499's subject (that freeze covers mongodb too) but ⛔ does not cite it, and [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499's criterion talks only about driver-memory. ⇒ ⛔ the seat did not apply the line to it — that would be exactly the 「各自发明代理判据」 the ruling forbids. Whether the mongodb half has any wake criterion at all is a question this ruling did not answer; raised to triage on Every card held under the #5499 driver-memory freeze has no fireable wake condition — the anchor is tracking and never closes, the freeze's stated wake has no card, and the sole existing hold carries no Restart-when: at all #17587.
• ⚠️ 51 of 104 open holds carry no Restart-when: in the body (49%). ⛔ That is a body-level reading, NOT a legality verdict — driver-memory / driver-mongodb execute() answer without running the command and without refusing — a declared, NON-optional contract member that no caller can tell apart from "ran and found nothing" #14082 proves a comment can carry it, and 9 of the 51 carry a target:* label (whether 「等 v18」 is a legal spelling is a口径 question, ⛔ not this seat's). The seat verified only its own lane: 7 engine holds lack a body line → 5 carry it in a comment (driver-mongodb: bulkUpdate's single bulkWrite is only atomic when the caller supplies a session — a mid-batch refusal without one leaves earlier ops applied #14169 · [finding] metadata: database-loader spells its own driver-capability predicate inline, duplicating resolveDriverExec one directory away #14121 · finding(objectql): the sibling [Registry] Collision warning ("ships from package") also double-quotes the package id #12789 · [finding] On SQLite, applyMigrationEntries runs a FULL table rebuild even when zero entries in the batch are honourable #12132 · [finding] The drift category vocabulary has no "report only" state, so a finding the platform will never reconcile must borrow needs_confirm and be declined by the reconciler #11721 — a locatability problem, ⛔ not illegality) · 2 carry it nowhere.
• ✅ docs: two prose notes still describe PHASE2_IMPLEMENTATION.md sections 4 and 5 as teaching the unresolvable @objectstack/core/security subpath, which PR #16205 repaired #16208 — the seat's OWN illegal hold, healed. R1 set pm:on-hold there on 2026-09-06 (5590656553) and ⛔ never wrote a Restart-when:. Fixed this round (5634608131) by mechanising triage's existing ruling (「站点二在该文件下次因别的原因被触碰时顺手改掉」) rather than inventing one: git log --oneline 5abca1792e..origin/main -- packages/core/src/security/security-scanner-retirement.pin.test.ts returns ANY commit. ⭐ Note the inverted direction — non-empty wakes it, ⛔ not returns 0. Today: 0 commits (control: same window over packages/core/src = 10 ⇒ ⛔ not a false zero); the stale parenthetical is still on main at :46 ⇒ the card's substance stands.
• ⛔ Reject specs that do not round-trip through JSON at put() — the option-1 tightening deferred by #7856 #8006 — deliberately NOT touched. Its restart condition is prose inside a maintainer ruling (5271020238, 2026-08-12). The gap is the spelling, not the criterion, and ⛔ rewriting a maintainer's words is not an execution seat's act. Raised to triage.
• ⚠️ driver-memory analytics 面的 generateSql 对 in/notIn/set/notSet 输出错误 SQL:回退成 = 且只取第一个值($in: ['100','200'] → WHERE code = '100') #5433 · driver-memory analytics 面:同一字段上的多个算子互相覆盖,{qty: {$gte:150, $lte:250}} 只剩最后一个 —— 区间塌成单边,结果被放大 #5440 · driver-memory analytics 面:flattenFilterCondition 对所有算子一律摊平数组比较数,{qty: {$eq: [100]}} 变成 $eq: 100(find() 取 0 行,analytics 取 1 行) #5442 · driver-memory analytics 面的 generateSql 把 contains 回显成 LIKE 'et'(没有 % 通配符)—— 回显的是等值匹配,执行的是子串匹配 #5444 · driver-memory 的两个过滤面对**比较值的种类**给出相反答案:{f: /re/}(正则)与 {f: ['x']}(数组)各差一个方向 —— 实测 #5354 still carry pm:on-hold while closed/not_planned — ⛔ left in place on purpose: those five ARE [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499's prescribed batch close, and the label records that they were disposed of while held. Erasing it erases the disposition record. Recorded here so the next round does not re-discover it as a bug.

⚠️ Carried forward — things the next occupant should NOT rediscover

• ⛔⛔ mcp__github__get_job_logs 只返回日志的 TAIL —— 失败断言在中段就够不着。 fix(platform-objects,cli): the generated i18n staleness predicate judges every section a run generated #17839 的 Test Core (6/6) 全量日志 29,317 字符,本席用四个不同的 tail_lines 调了四次,每次拿回同一段收尾(artifact 上传 → Post job cleanup)⇒ ⛔ 看不到哪个测试失败。⚠️ 而 dev 侧的 egress 也拦着 blob host(productionresultssa19.blob.core.windows.net,connect_rejected)⇒ 两边都读不到 ⇒ ⭐ 失败断言只能本地复现,⛔ 不能靠查日志。 ⇒ 把 CI 红送回 dev 时,必须把「我拿不到中段」明说,否则它会以为席位藏了信息。
  ⭐ 日志尾部仍有可用读数,别因为拿不到中段就当白板:check-test-completeness: OK (8 of 8 package(s) reported … 5173 test(s) declared and all accounted for) ⇒ 不是超时、不是没跑到,是断言失败;report-test-timings 捕获 309 file timings ⇒ 进程正常结束。这两条把嫌疑区从「环境」缩到「断言」。
• ⭐⭐ 判断一个红是不是本 PR 的,先读 BASE 的同名检查 —— 一次调用,⛔ 不要猜。 fix(platform-objects,cli): the generated i18n staleness predicate judges every section a run generated #17839 红时本席读 origin/main 6059b29c03:Test Core 六个分片 + 汇总门全绿,总红数 0 ⇒ 红是本 PR 的,⛔ 不是基线。这条比任何推理都便宜。
• ⚠️ dev 报「本地全绿」时要问它跑的是哪个 TIER。 fix(platform-objects,cli): the generated i18n staleness predicate judges every section a run generated #17839 的轮次跑了 @objectstack/cli 的 unit tier(198 files / 2830 tests),而 CI 的 shard 6/6 跑 8 个 package / 5173 tests ⇒ 差额就是嫌疑区。⛔ 「本地全绿」不是「CI 会绿」,⭐ 派发令该要求 dev 报出它跑的 tier 与用例数,而不只是「passed」。
• ⛔⛔⛔ 「export 自模块 ≠ 到达 entry」只在 entry 是 SELECTIVE 时成立 —— 星号链会把导出原样带过去,而字面 grep 模块路径永远看不见它。 R2 在 Generated non-objects i18n groups carry no provenance from EITHER mechanism — --no-objects-only fills leaves from source that no predicate judges #16872 上用坏方法判了 Clause-②: no,轮次证伪:packages/platform-objects/src/index.ts:27 是 export * from './apps/index.js',链下去的 barrel 显式带出那三个符号,构建产物 dist/index.d.ts:5 字面列出三者,./apps 还是独立已发布子路径。
  ⛔⛔ 而本席的控制项读到的正是反证,却被计为正证:控制项是「entry 有 10 条 export ⇒ 它是选择性的」,而那 10 条里 8 条是 export * —— 星号再导出是「选择性」的反面。⇒ ⭐⭐ 一个控制项必须能区分它要区分的两种情况;数 export 的条数区分不了具名与星号。
  ⇒ ⭐ 正确工具(轮次给的,已采用):grep 构建后的 entry .d.ts 找 SYMBOL NAME,带伪造名负控制项。 源码侧的快速判据只有先数 ^export \* 为 0 才可用。
  ⭐ 追溯检查 [finding] packages/objectql carries the last two live source copies of the falsified 'the strip is schema-uniform' premise — one of them contradicts its own file #17291(昨日同一坏方法,且已落地):安全。 packages/objectql/src/index.ts 有 0 条 export *、82 条全具名 ⇒ 该 entry 确实选择性,且那一轮另用真实构建独立验证(dist 命中 0,正控制项命中 4)。⇒ 方法是坏的,那个结果恰好是对的 —— ⛔ 不要因为结果对就留着方法。
• ⭐⭐ Clause-② 问的不是「闸门会不会红」,是「席内契约复核是否必过」。 Generated non-objects i18n groups carry no provenance from EITHER mechanism — --no-objects-only fills leaves from source that no predicate judges #16872 的轮次论证 path limb 与 T3 widening tell 都是 spec-scoped、本 diff 不碰 ⇒ 闸门不会红 —— 论证正确,但答的是另一个问题。裁 yes 的依据是:① 与 [finding] aggregate() IS on the IDataDriver contract and is masked as Promise[any] on both SQL drivers — #15267's census and its dispatch order both say it is not #17277(已发布类型面移动判 yes)同类,⛔ 同一类变更不能两天两判;② 「拿不准 ⇒ yes」。
• ⚠️ 一张卡可能带着另一个车道的过期 Claim:。 Generated non-objects i18n groups carry no provenance from EITHER mechanism — --no-objects-only fills leaves from source that no predicate judges #16872 上 domain:cli 席 09-11T21:31 的 claim 仍在,names 一个从未被推过的分支;该席 23:18 主动释放(剥 pm:dispatched + unassign),分诊 01:47 重路由,本席 09:43 认领 ⇒ ⭐ 无竞态,但两条 claim 会让 dev 在「验证最新 claim 是否 names 我的分支」时困惑 ⇒ 发一条交接说明把时间线写清(5645105865)。
• ⚠️⚠️ 读数也会被共享检出误导 —— 不只是写。 车道规矩是「⛔ 永不编辑共享检出」,但 A writable package created via POST /api/v1/packages is registered in memory only — it does not survive a restart, and leaves its published metadata orphaned #17676 的轮次第一遍在共享检出(HEAD f721ef0ff2)上读行号,把一条警告报成 protocol.ts:22146;在 worktree 的派发基 c9eb773bab 上重取,真值是 22353。同一读数,不同的树。 ⇒ ⭐ 任何要写进卡或裁决的行号,必须在派发基上取,并在报告里写明取自哪个 sha。
• ⭐⭐ 一个 pin 可以为「缺陷不可能发生的那个组合」建模,于是永远是绿的。 A writable package created via POST /api/v1/packages is registered in memory only — it does not survive a restart, and leaves its published metadata orphaned #17676 的 durable-package.test.ts 把 services map 硬编码成 new Map([['package', …]]),overrides 只能换实现、⛔ 不能移除服务 ⇒ 7 个测试全部跑 service-存在分支,而发出缺陷日志的 service-缺席分支从该文件结构性不可达。⇒ ⭐ 问一个 pin「它覆盖了什么」时,真正的问题是 「它的 fixture 能不能表达出缺陷发生的那个组合」 —— 覆盖率数字答不了这个。
• ⛔⛔ A CONTAINER RESTART SILENTLY KILLS THE SEAT'S HEARTBEAT — it happened at ~2026-09-11T18:5xZ and CronList came back EMPTY. The hourly patrol is a session-only CronCreate job (send_later, the durable MCP channel, vanished mid-session earlier in R1 and has not returned). ⇒ ⭐ the loop can die without any error, at any moment, and nothing announces it — the seat simply stops waking.
  ⇒ ⭐⭐ Every patrol's FIRST act must be CronList: if it is empty, the container restarted — re-create the job immediately and record the loss. The rebuilt job carries that instruction in its own prompt text, so the next firing re-arms itself.
  ⭐ What a restart does NOT touch (measured, ⛔ not assumed): the seat post, every label and comment already written, the git checkout, the scratchpad — and GitHub-side merge state. docs(objectql): the last two carriers of the falsified "schema-uniform" premise state what the tree does #17717 was added_to_merge_queue at 18:42:38Z, the container died after, and the PR was still queued with 33/33 green and no removal event afterwards. ⇒ ⛔ never re-arm auto-merge on a restart; read the timeline first.
  ⚠️ What IS lost: any run_in_background watcher. One was mid-flight (a seat-post PATCH + a landing watch) — the PATCH had already landed (verified by read-back, ⛔ not assumed), the watch did not. ⇒ verify, never assume, which half of an interrupted job completed.
• ⚠️⚠️ A negative control needs its ANCHOR drawn from the half it is testing — this seat botched the same control TWICE in one round. Proving a diff is comment-only with stripComments needs two controls: a code edit must read as a change, and a comment edit must read identical. Both times the seat wrote src.replace('export', …) as the code mutation, and both times the first export in the file sits inside a header COMMENT — so the mutation was stripped, the control returned false, and that limb was void. ⭐ The fix that works: take a line out of stripComments(src) itself (guaranteed code), verify it is unique in the raw source, then mutate that. ⇒ ⛔ never guess an anchor; draw it from the population you are testing, exactly as 「a control that FAILS to fire voids the reading」 already demands.
• ⭐⭐⭐ skip-changeset vs a patch changeset is decided by ONE measurement: does the diff publish a byte from a released package? AGENTS.md:1042 — 「A bug fix in a released package takes a patch changeset — never none, and ⛔ never skip-changeset: that label is for a diff that publishes nothing from any released package.」
  ⚠️⚠️ R1's three comment-only PRs split, and the split looks arbitrary until you read what each decision RESTED ON:
  · docs(metadata-protocol,objectql): the summary column comments state the post-#16318 representation #17701 (metadata-protocol) and docs(core,driver-sql): the three boot-refusal comments state the registered position, not the pre-#16404 one #17702 (core + driver-sql) → patch, because each dev measured after a real build that its corrected TSDoc reaches dist/index.d.ts.
  · docs(objectql): the last two carriers of the falsified "schema-uniform" premise state what the tree does #17717 (objectql, [finding] packages/objectql carries the last two live source copies of the falsified 'the strip is schema-uniform' premise — one of them contradicts its own file #17291) → skip-changeset, because the same measurement returns 0.
  ⇒ ⛔ They are NOT precedent for 「comment-only ⇒ patch」 — the round on [finding] packages/objectql carries the last two live source copies of the falsified 'the strip is schema-uniform' premise — one of them contradicts its own file #17291 read them that way and recommended patch; the seat ruled the other way and it was ⛔ not a departure. Same rule, opposite measurement, opposite outcome.
  ⭐ The mechanism, and the cheap second route that does not need a build: a comment reaches .d.ts only if its docblock sits on a symbol the package ENTRY re-exports. preserveAuditIgnoredOnInsertWarning is exported from rule-validator.ts but packages/objectql/src/index.ts:437 re-exports only three siblings from that same file — so it never reaches an entry, and neither does its docblock. Control: that entry carries 82 export statements, so it is selective, ⛔ not empty. ⚠️ And a comment inside a function body never reaches a .d.ts under any configuration.
  ⛔ files[] is not the discriminator — all three packages ship the identical ['dist','README.md','CHANGELOG.md'].
• ⚠️ Applying skip-changeset has a documented clobber (pr-automation.yml:77-84): applied → stripped by the size labeler's PUT seconds later → re-applied. ⭐ Apply it AFTER the push settles so the labeler has already run, then read back; R1 applied it post-push and it survived four checks over 80s. ⭐ With the label present Check Changeset reports skipped, ⛔ not success — that is the correct green for this class.
• ⭐⭐⭐ Check Changeset's clause-② axis reads TWO carriers, and the LABEL ALONE forces yes — a no in the PR body CANNOT clear the red while needs:contract-review is on the PR. scripts/check-changeset-no-major.mjs:

  if (carrier || (line?.kind === 'declared' && line.value === 'yes')) return { value: 'yes', ... };

  ⇒ on fix(metadata-protocol): the seed-tenancy organization probe records the operator channel as is, empty included #17709 the body read no and the axis still read yes, and the gate reported them 「disagreeing inside one PR」. The round drove both legs locally on the real tree differing in the label alone — present → exit 1, absent → exit 0 — so the label is the cause and the control fires. ⭐ The remedy is the seat stripping both carriers, which is the gate's own words: the carrier 「is the review seat's to place and to clear」. ⛔ A dev cannot clear this red, and asking them to try wastes a round.
  ⭐ And the strip DOES re-fire the gate: pr-automation.yml subscribes to label events (and to edited, 「load-bearing, not decoration」 Check Changeset concludes success when it measured nothing, and no edited trigger ever re-reads a Clause-②: line added after the last push — a correct seat action leaves the level axis unjudged behind a green check #16776). Measured: strip at ~16:53Z → new run at 16:53:59Z → success.
• ⭐⭐ A local gate sweep CANNOT see the clause-② level axis — it reads GREEN on a PR that CI will refuse. With no --event payload, check-changeset-no-major.mjs takes the no-pull-request branch and exits 0: there is no PR body or label list to read locally. ⇒ ⛔ a local green on that family is not evidence about this axis, and a dev reporting 「all N gates green」 has said nothing about it. The script ships the remedy (--event with a payload naming body + labels); what is missing is a sweep that synthesises the payload from the open PR. ⚠️ This is why fix(core, driver-memory): one reading of the dateRange array arm — an ARITY case in the conformance kit, and the cube face stops dropping the window #17694 and fix(metadata-protocol): the seed-tenancy organization probe records the operator channel as is, empty included #17709 both reached CI red after clean local sweeps.
• ⭐⭐⭐ Check Changeset's 「clause-② YES but nothing graded minor」 red has TWO answers and they are ⛔ NOT interchangeable — R1 hit both, one hour apart.
  · fix(core, driver-memory): one reading of the dateRange array arm — an ARITY case in the conformance kit, and the cube face stops dropping the window #17694 → path 1 (raise the level). The declaration was right: ANALYTICS_DATE_RANGE_NOT_A_WINDOW is a genuinely new exported symbol on @objectstack/core, re-exported from the entry. A purely additive widening takes at least minor (maintainer ruling 2026-09-04, decision batch [WIP] Add query enhancements and advanced validation features #35, on finding(changeset): two independent contract reviews read the repo's own history to opposite bumps for "add an exported symbol to a published index" #15294).
  · fix(metadata-protocol): the seed-tenancy organization probe records the operator channel as is, empty included #17709 → path 2 (re-declare no). The declaration was wrong — this seat's own yes rested on a labelled READING (「organizationProbeError reaches the published SeedTenancyBackfillStatus」) that the round falsified, exactly as the order told it to try. Re-measured independently: it is a local variable (seed-tenancy-backfill.ts:1327) flowing only into a warn line's meta (:1402), on no exported type (⛔ not SeedTenancyBackfillStatus:188, ⛔ not SeedTenancyBackfillResult:265), and the diff moves no export line. Control fires both ways: a throw at the organization probe does ⛔ not reach JSON.stringify(result); the same throw at the split probe does, in result.detail.
  ⇒ ⭐⭐ The deciding question is never 「which path clears the gate」 — it is 「which statement is TRUE」. Raising fix(metadata-protocol): the seed-tenancy organization probe records the operator channel as is, empty included #17709 to minor would have asserted a published-surface widening in the changelog that does not exist; that is a release-level falsehood bought to turn a check green. ⛔ Never available.
  ⇒ ⭐ 「声明被复核推翻 ⛔ 不作席位过失」 and 「Clause-② 按设计临时…⛔ 非终审」 — a yes re-declared no on measurement is the mechanism working. But ⚠️ the conservative 「拿不准 ⇒ yes」 rule is for unresolved uncertainty; ⛔ it is not a licence to freeze a guess after measurement resolves it.
• ⚠️ This seat's dispatch order repeated a COUNT the card got wrong, without checking it. metadata-protocol: the organization probe records 'unknown error' for an empty message channel, unlike the other three raw-exec sites #17167's card says 「the other three」 operatorFacingErrorText sites; the population is five call sites, so the aligned one has four siblings. ⇒ ⛔ a number inherited from a card is a reading, and this seat must label it as one — it labelled the card's mechanism claims but passed its counts through unmarked.
• ⭐ A one-line-looking fix can be carrying a second fact. metadata-protocol: the organization probe records 'unknown error' for an empty message channel, unlike the other three raw-exec sites #17167's placeholder || 'unknown error' also encoded 「did it fail」, because the site read organizationProbeError === '' as 「the probe did not fail」. The round's ablation showed a bare removal routes a thrown '' to status no-organization-yet with no warning at all ⇒ a published status value is one branch away. The repair moved the fact into the type (string | undefined). ⛔ Never dispatch a 「just delete the fallback」 order without asking what the fallback also encodes.
• ⛔⛔⛔ PROTOCOL VIOLATION, this seat's, repeated in EVERY R1 dispatch: the Claim: comment did not name the dev's branch. AGENTS.md:394-401 — the identity record is 「first line beginning Claim:, then the session ID and the branch (claude/issue-<n>-<slug>)」, a PM dispatch 「posts the Claim: naming the dev's branch (step 2)」, and the executor 「verifies that the newest Claim: names its branch (on a mismatch it stops and reports)」. ⇒ ⛔ that verification was structurally impossible against this seat's claims all round — the mutual-exclusion mechanism could not have caught a second session dispatching the same card.
  ⚠️ ⭐ TWO separate rounds reported it and the first was read past ([finding] aggregate() IS on the IDataDriver contract and is masked as Promise[any] on both SQL drivers — #15267's census and its dispatch order both say it is not #17277's report said 「no branch to verify against」; [finding] Three source comments still say the boot-refusal codes are "deliberately NOT wire vocabulary" — #16649 registered them, so all three are false in packages/core and packages/drivers/driver-sql #16884's filed it as a finding aimed at this seat). ⛔ That delay is this seat's error, not theirs. Amended on the three live claims ([finding] Three source comments still say the boot-refusal codes are "deliberately NOT wire vocabulary" — #16649 registered them, so all three are false in packages/core and packages/drivers/driver-sql #16884 · Sweep the stale summary is a table.float comments left behind by #16318's NUMERIC representation change — nine sites in four packages, the sweep already exists on a sibling branch #17144 · metadata-protocol: the organization probe records 'unknown error' for an empty message channel, unlike the other three raw-exec sites #17167) with an edit note naming the branch.
  ⇒ ⭐ The dispatch order must SPECIFY the branch name and the Claim: must carry it — the PM decides claude/issue-<n>-<slug>, the dev uses it, the dev can then verify. ⛔ Do not post a claim without it.
• ⚠️⚠️ A line-oriented git grep structurally CANNOT see a phrase that wraps across a newline — SECOND occurrence in R1. On [finding] Three source comments still say the boot-refusal codes are "deliberately NOT wire vocabulary" — #16649 registered them, so all three are false in packages/core and packages/drivers/driver-sql #16884 this seat's git grep -l 'deliberately NOT wire vocabulary' read 1 where the card said 3; the tree was right and the instrument was wrong — plugin-contract.ts wraps the phrase between wire and vocabulary (line-based 1, continuation-lines-joined 2), and the third site never carried that phrase at all (the card's table gives it a different false claim). ⭐ The first occurrence was R1's git grep "one day earlier" reading 0 on driver-sql: a multiple: true boolean/toggle column reads back as a single true — formatOutput's booleanFields pass collapses the parsed array, so a stored [false] presents as true #17586 — a trap that card had predicted in advance. ⇒ ⛔ never conclude 「already fixed」 from a single-phrase line grep; join continuation lines, or build the predicate from the card's table one phrase per row.
• ⭐⭐ The repo ships the RIGHT instrument for 「is this diff comment-only?」 — scripts/js-comment-mask.mjs (stripComments). Compare the executable token stream (strip comments, drop whitespace-only lines, hash) instead of eyeballing +/- lines. Used on docs(core,driver-sql): the three boot-refusal comments state the registered position, not the pre-#16404 one #17702: all three files code-identical (3305c756ddfea806 / c9c1b9728c24e313 / 184e2f332da9d7fd) with comments moved — and this seat's hashes matched the round's independently. ⚠️ Both directions of the control must fire: this seat's first negative control used a mutation anchor that was not in the file, so it read 「false」 and voided that limb until re-run with an anchor proved present.
• ⭐ pnpm --filter A --filter B run test --workspace-concurrency=2 forwards the flag to the SCRIPT, not to pnpm — vitest answers CACError: Unknown option --workspaceConcurrency and the run dies in ~2s. ⇒ the flag goes before the filters.
• ⭐⭐⭐ THE TEMPLATE DEFECT THAT DEFEATED A LANDING GATE — this seat's own, and the sharpest thing R1 found. The dispatch-order boilerplate bullet - **`Clause-②: yes|no` must appear in the PR BODY at column 0.** is key-initial, so check-clause2-carriers.mjs's readClause2Line parses it and returns {kind:'declared', value:'yes'} — the yes|no placeholder opens with a valid token and | passes the (?[A-Za-z0-9_]) boundary. ⇒ on [finding] aggregate() IS on the IDataDriver contract and is masked as Promise[any] on both SQL drivers — #15267's census and its dispatch order both say it is not #17277 and [finding] insertManyData attributes a batch-union dropped-field name to every row that supplied it — ruling C's per-row hook exemption falsifies that inference #17290 the declaration limb was reading the seat's own instruction as a judgement, and --pair 17689 returned exit 0 on it — precondition ② of the landing check, on a PR already armed with auto-merge. ⭐ Verified against the exported function with three controls (yes→yes, no→no, prose→null).
  ⛔ The order's sentence 「the gate reads it there and never reads a comment」 is FALSE: two gates read two carriers — Check Changeset reads the PR body, --pair reads the card's claim comment. ⇒ ⭐ every dispatch order must carry a real line-anchored Clause-②: yes|no declaration of the SEAT's own, above any line that merely explains the key. readClause2Line returns on the FIRST match, so position is the whole remedy.
  ⇒ Fixed by hand on [finding] aggregate() IS on the IDataDriver contract and is masked as Promise[any] on both SQL drivers — #15267's census and its dispatch order both say it is not #17277 · [finding] insertManyData attributes a batch-union dropped-field name to every row that supplied it — ruling C's per-row hook exemption falsifies that inference #17290 · The shared dateRange conformance kit has no ARITY case, so an odd-sized array arm is governed nowhere — and driver-memory's cube face drops such a window entirely #17596 (real declaration inserted above; instruction neutralised; edit note on each). Re-run: --pair 17689 → 0, --pair 17694 → 0, --pair 17688 → 0, one match each and each a judgement.
  ⭐ Already a known card — [finding] check-clause2-carriers reads a key-INITIAL describing line as a declaration — its own self-test asserts the general property "only DESCRIBES ⇒ MISSING", and the fixture pinning it covers only the other half #17098 (domain:skills), ⛔ so no duplicate filed. This seat added the measurement as corroboration (5636056726) because that card records only the fail-closed direction (ci: every Test Core run publishes the slowest test files and packages beside their pinned weights (maintainer-directed, part B measurement) #16454: a true no got a review hung). ⚠️ The same defect also produces a false GREEN, which its 「the cost is bounded but recurring」 framing understates. ⚠️ Prevalence board-wide is unmeasured: --json reports findings and declarationLimb counts only (13 open PRs / 12 pairs / absent 0, missing 1, sibling 0) and ⛔ does not expose the matched line for passing pairs.
• ⚠️⚠️ A grep -c for removed text is the wrong instrument — FOUR times in R1. It cannot tell 「the claim stands」 from 「the claim is quoted and refuted」. On the feat(driver-sql,driver-turso): aggregate() publishes its declared return type, not any (#17277) #17689 / fix(core, driver-memory): one reading of the dateRange array arm — an ARITY case in the conformance kit, and the cube face stops dropping the window #17694 / fix(metadata-protocol): insertManyData reports the dropped-field union at BATCH level instead of naming rows it cannot identify #17688 landing checks all three controls read non-zero where 0 was expected, and all three were comment quotations of the removed code. ⭐ The instrument that works: count only lines that are not comments (*, //, /*), and prove it fires on a real code line. Done that way: [finding] insertManyData attributes a batch-union dropped-field name to every row that supplied it — ruling C's per-row hook exemption falsifies that inference #17290's false inference 0 in code, The shared dateRange conformance kit has no ARITY case, so an odd-sized array arm is governed nowhere — and driver-memory's cube face drops such a window entirely #17596's dropping guard 0 in code, [finding] aggregate() IS on the IDataDriver contract and is masked as Promise[any] on both SQL drivers — #15267's census and its dispatch order both say it is not #17277's false claim 0 in code, controls firing at 1. ⛔ The naive count would have failed all three landings, or passed them for the wrong reason.
• ⚠️ (original note, kept) A grep -c for a corrected comment's OLD TEXT is the wrong instrument — it cannot tell 「the false claim stands」 from 「the false claim is quoted and refuted」. On feat(driver-sql,driver-turso): aggregate() publishes its declared return type, not any (#17277) #17689's landing check this seat's control read 1 where 0 was expected; the line was "aggregate is not on that contract" — was FALSE. ⇒ read the context, ⛔ never the substring count. Third instrument error of this class in R1.
• ⚠️ Observed, ⛔ NOT acted on (another lane): PR docs(spec): state the retired allowRestore / allowPurge parse-time accept set exactly #17485 / card ObjectPermissionSchema's retired allowRestore/allowPurge: only literal false parses (not a truthy/falsy split), and no post-parse guard can ever see either key #17425 (domain:spec) is a C6 half-state — clause-② gate cleared on both carriers at head a9469d6b44 with no ## Contract review record on that head. Surfaced by this seat's sweep. ⛔ Not this lane's card; reported here only so it is not lost.
• ⭐⭐ GET /search/issues is BLOCKED in this session — it answers {"message":"This GitHub API path is not available: sessions are bound to their configured repositories…"} with no total_count. ⚠️ The dangerous part: parsing it naively yields total_count = None, which reads like "0 results" and would silently pass a dedup check. ⇒ dedup must use a repo-scoped listing + local grep with a declared control. Done that way this round: 566 open issues over 6 pages, control worktree = 24.
• ⚠️ No agent in this session can delete a remote branch — BOTH channels refuse. git push origin --delete → RPC failed; HTTP 403; DELETE /git/refs/heads/… → 403 「Write access to this GitHub API path is not permitted through this proxy.」 Re-tested 2026-09-12 on a fresh orphan (claude/issue-17676-…): still 403 on the REST channel — ⛔ not inherited from yesterday. ⇒ orphans accumulate and only a maintainer can clear them.
  ⛔⛔ CORRECTION 2026-09-12 — R1 recorded 「4 zero-commit claude/* branches (of 349)」 and THAT NUMBER CAME FROM A BROKEN PREDICATE. ⛔ Do not reuse it. 「sha == origin/main」 only catches branches equal to main at that instant, so it silently drops every zero-commit branch cut against an earlier main — which is exactly why today's fresh orphan (c9eb773bab, the dispatch base) did not show up under it while main had moved to c1078a5591.
  ⚠️ The obvious repair is broken the other way: an ancestor predicate (git merge-base --is-ancestor) returns 219 of 366, but it also matches branches from the merged era, and the control could not be taken at all — the branch chosen as the negative control had already been deleted. ⇒ ⭐⭐ This seat cannot currently measure the orphan population and declines to ship either number. 「控制项不发火 ⇒ 读数作废」 applies to the seat's own census exactly as it applies to a dev's.
• ⭐ git push … 2>&1 | tail reports tail's exit, not the push's. This seat's delete attempt printed exit=0 while failing with 403 — the pipe-exit trap, from this very list, fired again. ⛔ The only evidence that counted was the independent git ls-remote re-read.
• metadata-protocol's live-DB CI step supplies only OS_TEST_MYSQL_URL, so the new catalog presence probe's PostgreSQL arm is pinned as TEXT and has never been executed #17621 (filed this round, ungraded): the PG arm of the new read-probe.ts is text-pinned only, never executed. ci.yml:1415 gives metadata-protocol only OS_TEST_MYSQL_URL; both URLs go to the driver-sql job at :1319-1320, and metadata-protocol has no pg dependency. ⇒ this seat's own read-only fence on driver-sql closed the only live-PG door. ⛔ Not urgent — the four-verdict fence makes a wrong PG arm loud ('unreadable' + warn), never a silent 'absent'.
• fix(metadata-protocol): one shared non-raising table-presence probe, so a normal boot stops printing DATABASE_ERROR for an expected miss (#17175) #17617 carried a test-only addition to packages/runtime (domain:cli, +128/−0, no source change). Accepted and declared, and put to triage as a precedent question: does a test-only cross-package addition require the cross-domain exception path? ⛔ Unsettled; this PR is the card to rule on.
• SeedTenancyBackfillStatus is a public export that gained 'unreadable'. Ruled Clause-②: no (the member is reachable only where the status previously lied). ⭐ The changeset was graded minor anyway, so a later yes ruling costs nothing — cheap insurance this lane has needed before.
• Class census left open on purpose: three further WHERE 1 = 0 sites exist (runtime-index-preflight.ts:162, seed-tenancy-backfill.ts:775, cli/.../duplicates.ts:393), reported ⛔ not swept. None prints on a normal boot; each has a named successor.

✅ Serial relay DISCHARGED — scripts/engine-double-contract.pinned.json

#17580 → #17588 relay completed correctly. On origin/main the ledger carries 3 entries naming protocol.meta-types-degenerate-derivation.test.ts and 3 naming seed-loader-summary-scope.test.ts; 784 rows = 781 + 3. ⭐ --write reported 0 added, 0 lost and left a clean tree — i.e. the regeneration proved both sides survived rather than repairing a loss. ⚠️ Keep the discipline: that path is merge: unspecified, so a dropped side would have merged exit 0 with no conflict marker.

⚠️ The relay hazard, kept for the next occupant

#17580 and #17588 both add +15/−0 to it (each adds a test registering an engine double and ran the gate's own --write). ⇒ #17580 has the baton; #17588 merges origin/main and regenerates after it lands. ⛔ Never a textual merge of the two blocks.

⚠️ git check-attr merge on that path reports unspecified — it is not routed to the merge=os-regen driver (control: packages/spec/spec-changes.json is routed). ⇒ it merges with exit 0 and no conflict marker even if a side is lost. The regen discipline is the only thing standing between this and a silent drop.

⛔ #16746 RELEASED back to the queue — ⛔ do not read the earlier "in flight" row as current

p1, ruling in hand, not a merit stop. The round confirmed all three Zone-2 assumptions and the card's premise (a permissionless caller gets 403 on GET /api/v1/meta/apps/setup), then falsified this seat's suggested route by exhaustive measurement of the lever space: dropping group_integrations' gate alone changes nothing (the app-level gate fires first); dropping setup.access alone still does not reach the card and already serves 14 other Setup entries to every signed-in user; only dropping both reaches connect_agent, and it serves those 14 alongside. ⇒ hard stop 3, measured.

The one defect-free fix is a navigationContributions entry inside CONNECT_AGENT_UI_BUNDLE (packages/mcp/src/connect-ui.ts, app account, group grp_account_developer) — it registers exactly when the page registers, so it needs no gate. That is domain:cli ⇒ hard stop 1 ⇒ released with Release: line + pm:retriage (5627142970).
⭐ Worth keeping: requiresService 'mcp' is strictly weaker than the page's registration condition — plugin.ts:270 registers the service unconditionally while the UI bundle at :628 sits behind isMcpServerEnabled() — so an account.app.ts entry gated that way 404s for every signed-in user on an opted-out deployment.

R1 ledger — landed 0, released 1, re-dispatched 1, retriaged 6

⛔ Zero landings so far is honest: two of the three first-batch cards returned measurements that falsified their dispatch premise, which is the third-tier dispatch working, not a failure. ⛔ Never re-file either as a rework.

Not dispatched, and why — established card-by-card

• Phase 1b of #11333: make the registered granted-permission set actually REFUSE — the ADR-0025 materialize seam that gives each plugin its own SecurePluginContext #17147 (p1) — ⛔ NOT dispatchable; pm:retriage raised. The card asks a dev to build the ADR-0025 materialize seam, which maintainer ruling 5486840233 (2026-09-01, comment on Phase 1 of #11333: wire granted_permissions into PluginPermissionEnforcer (F4) as the load-time gate #13457) fences verbatim: 「The materialize seam (per-plugin context construction) belongs to the ADR-0025 install-flow design work, ⛔ not to be improvised inside either half.」 Relocating that work into a third card does not discharge the fence. Building it is the maintainer floor (ADR + security boundary). Triage's grading comment 5620285623 does not mention the ruling. ⇒ dissent filed (5626888839), grade is triage's to change. Card now carries pm:retriage.

Half-state patrol anchor (#9857) — read at seating, sweep 2026-09-10T19:46:50Z

No rendered H row names a domain:engine card, PR, or this seat post. The only lane mention is #13457 appearing as a blocker target inside #11333's H19/H26 rows. ⚠️ This is a LOWER BOUND, not a clean bill: the sweep found 316 half-states and the body trim rendered 19, omitting 297 (H19 8/24, H52 5/31, H9 0/15, …). The omitted rows live only in the workflow run log.

⚠️ Anchor-wide, unrelated to this lane but recorded because it degrades every row: H22's rate premise has drifted — the sweep observed ~148.9 closed-issue updates/day against a pinned 415.1/day (factor 0.36, outside the 2× band), so H22's stated day-reach is misdescribed by that factor. ⛔ A sweep never overwrites the pin; it needs a hand re-measure. Not this lane's to fix.

⚠️ Standing caution carried forward

#13457 must NOT be closed until #13458 re-points its Blocked-by: at #17147. #13457 is assigned to os-sam and is not this seat's to touch.

4. Notes — lane disciplines that are current

Measurement

• ⭐⭐ A control that FAILS to fire voids the reading. R3 needed three attempts before one fired on a skip/quarantine sweep; the first two returned 0 themselves and would each have let a "0 added" claim stand on no evidence.
• ⭐⭐ A number produced by a bad parse is not a reading, and printing it does not make it one. R3 produced three: a false parent count of 11 (%H %P %s + awk — the parent list and the subject both contain spaces; use git show -s --format='%p' <sha> | wc -w), a docs sweep of 117 that conflated three different type vocabularies, and an "old behaviour gone" count that read higher on main than on base because the landed code carries comments naming the expression it replaced. ⛔ Separate code from comments before counting either.
• ⭐⭐ A number must name its population. The changeset's 388 was correct — matching lines under driver-sql/src/. Because it never said so, three readers computed three different correct numbers (dev 371/372, seat 405).
• ⭐ $? after a pipe is the pipe's LAST stage. cmd | head reports head's status. This seat re-committed that error twice in one shift after warning devs about it. Redirect to a file instead.
• ⭐ Exit code 3 = PREREQUISITE NOT MET — nothing was measured. ⛔ Never a pass.

Reading CI

• ⭐⭐ Judge a red by the whole run's conclusion + a per-head tree comparison. ⛔ Never the check NAME — and the name misleads in both directions. Temporal Conformance (live PG + MySQL) actually runs the whole driver-sql suite (ci.yml:1316 step name, :1300 comment), with OS_EXPECT_LIVE_DIALECT_MATRIX=1 turning a missing server into a red rather than a skip. ⚠️ A cancelled run can still hold a job whose own conclusion is failure.
• ⭐⭐ Directory byte-identity proves nothing across a workspace edge. R3's first red had packages/runtime byte-identical to its base while the failure was 100 % the PR's — the fixture that tripped the door was imported from another package. The recorded "not ours" lane pattern needs both its limbs; one limb firing means the assertion decides.
• ⭐⭐ PR-side CI runs the affected subset; the merge queue runs the FULL suite. R3's queue build failed on packages/qa/dogfood, which the PR's own CI had never exercised. ⛔ Green PR CI is not evidence a class is clean.
• ⚠️ A merge-queue failure can be a semantic collision the queue itself created — two branches, each sound alone, meeting for the first time. Fix it in the PR being landed; the queue tests the combination.

Census discipline

• ⭐⭐ A census that misses a whole class usually has a wrong PREDICATE, not a lazy author. R3's first census cross-referenced the literal token registerObject(, so every registration arriving through registerApp or a plugin manifest was invisible, and its hand-written vocabulary lacked checkbox. Its "0 reach a door" was honest and wrong. ⛔ Ask which doors a zero covered before believing it. A sound census enumerates the door set from code and follows importers — the fixture that broke the queue carried no door token at all.
• ⭐ A card's own body under-counts the fix surface, and so does the seat's own sweep. [finding] driver-sql and both migration generators default an absent or unknown field type to DIFFERENT families — string versus text, so the unvalidated authoring door produces two different columns #16319's body said "one character each side"; triage said 4 on the generator side; this seat measured 7 on the driver side and 7 was wrong in both directions (真数 11 — it missed the ?? spelling — plus 2 introspection sites that are a different question). ⛔ Never hand a hand-rolled half-census to a dev as authoritative while telling them to census.
• ⭐⭐ A discovered error triggers a sweep of its own CLASS.
• ⭐⭐ Read the newest state TRANSITION, not the newest MENTION of a blocker. A replaced blocker and a discharged one look identical in a thread.

Filing

• ⭐ A pin that can turn itself red is its own carrier. R3 declined to file a card for the driver-side membership arm and for a dead case 'string': arm, on that ground. The door then caught a mis-spelled field type written the same day by another author, in the merge queue, before it reached anyone — a card would have carried nothing CI does not shout.
• ⭐⭐ An Execution paragraph is authoritative about INTENT, not immune to being wrong (driver-sql: store the file family (file / image / avatar / video / audio) as the bare sys_file id in a string column — drop FILE_REFERENCE_TYPES from JSON_COLUMN_TYPES, per-deployment switch on the adr-0104-file-references flag (ruling on #15041, step 2) #15989: following it literally would have destroyed data).
• ⛔ Never let a dev take the cheap ADR-0087 disposition unmeasured.

Channel readings — ⛔ one call each, not rules

• DELETE /issues/{n}/assignees answers 415 without Content-Type: application/json. Looks like permissions. Is not.
• enable_pr_auto_merge's echo, the REST auto_merge.merge_method field and the webhook all three report merge for a squash landing. ⭐ Mechanism, found in R3: the repo sets allow_merge_commit=False / allow_squash_merge=True, so that value names a method this repo forbids — squash is the only reachable one. ⛔ The parent count remains the only instrument.
• ⭐ auto_merge reads OFF once the queue takes ownership. That is the expected post-enqueue state, ⛔ not evidence the arm failed — this seat misread it once and built a false "the tool reports success while doing nothing" theory on an empty field in the echo. Verify queue membership by the TIMELINE.
• GH006: a branch in a merge queue cannot be pushed to. A dev that finds a newer main mid-run must leave the merge unpushed rather than dequeue.
• Queue timing, 6 landings: enqueue lag 30 s–3 min; enqueue → merge 25m04s / 25m10s / 25m35s / 29m17s / 27m10s.
• The docs-drift bot's emitter-vs-inputs blind spot fired repeatedly. ⛔ A green drift check is not a clean bill of health.

R1 measurement lessons (2026-09-11)

• ⭐⭐ Read CI as the LATEST run per check name. A check-runs listing returns every historical run, so counting raw conclusions over-reports red. This seat reported fix(driver-sql): a multiple: true boolean column keeps its $contains membership filter (#17343) #17577 as "4 non-green" when it had one — the three Check Changeset rows were superseded runs and the newest was already success. ⛔ Group by name, take max started_at, then judge.
• ⭐⭐ The Clause-② line must be in the PR BODY, at column 0. Check Changeset reads it there and never reads the claim comment. All three of R1's PRs shipped without it and all three went red on a declaration this seat had already made. ⇒ every dispatch order must say so. ⭐ The gate re-reads on the edited event, so the red clears with no push and no re-run — a body edit is the whole remedy.
• ⭐⭐ A REST PATCH to a PR body appends the platform's own footer — and POST (create) does NOT. Refined on fix(core, driver-memory): one reading of the dateRange array arm — an ARITY case in the conformance kit, and the cube face stops dropping the window #17694: REST create stored the author's footer byte-identical and appended nothing; REST edit appended the platform block on top of the existing one, leaving two. ⇒ the hazard is the edit verb specifically. Strip every footer from the body you send, then read back and confirm exactly one. This seat produced a duplicate on fix(metadata-protocol): serve a real JSON Schema for action from /meta/types #17580 doing precisely what a dev had already documented as a hazard.
• ⭐ A PR-body edit is CHEAP and its check movement is benign — know both halves. It re-runs only Check Changeset, ⛔ not the pipeline, so a body fix costs no CI cycle. ⚠️ But it also flips Auto Label and Check PR Size from success to skipped, because they stand down on an edited event. ⇒ ⛔ that pair going skipped after a body edit is not a regression; measured on fix(core, driver-memory): one reading of the dateRange array arm — an ARITY case in the conformance kit, and the cube face stops dropping the window #17694.
• ⭐⭐ A CI gate can be driven LOCALLY before pushing, and the round that did it saved a red cycle. On fix(core, driver-memory): one reading of the dateRange array arm — an ARITY case in the conformance kit, and the cube face stops dropping the window #17694 the dev ran node scripts/check-changeset-no-major.mjs --base origin/main --event EVENT with the real PR body in a synthesised payload: exit 1 on the old grade, exit 0 on the new one — the failure reproduced and the fix proven before the push. ⇒ ask for this shape whenever a gate script is the thing that went red.
• ⭐⭐ premise_still_valid: false + pr: null is a legitimate terminal report. It happened twice in R1 (metadata-protocol: /meta/types serves an EMPTY JSON Schema for action — the output-mode derivation of its ZodPipe has no properties, and the hand-crafted fallback never fires #17501's C ruling, Setup → Connect an Agent is admin-only, but POST /api/v1/keys mints per-user keys for anyone — the "acts as you" self-service promise cannot be kept by non-admins #16746's route) and both were correct — the measurement killed the dispatch premise before any code was written. ⛔ Never re-file as a rework, never count as a failed dispatch.
• ⭐⭐ Zone-2 assumptions must be labelled as readings vs. measurements, and devs must be told to refute them. R1 shipped one wrong file name (plugins/organizations/… for plugin-security/claim-seed-ownership.ts) and the dev caught it because the order said "my reading of the card's prose, not my measurement". ⛔ An unlabelled assumption is indistinguishable from a fence.
• ⚠️ The seat's own slip, recorded: a full label-set PUT re-asserts domain:*. Closing Every card held under the #5499 driver-memory freeze has no fireable wake condition — the anchor is tracking and never closes, the freeze's stated wake has no card, and the sole existing hold carries no Restart-when: at all #17587 this round the seat used PUT /labels with the whole target set — which includes domain:engine — instead of the single-label DELETE. ⛔ Net effect was nil (read-back identical but for the intended removal), but the rule exists so a seat cannot regrade by accident, and the instrument was the wrong one. The three claims that followed used DELETE + POST.
• ⭐ A lane inventory taken at the START of a shift is not the lane at the END of one. R3 reported 0 dispatchable while triage graded ~18 cards into the lane during its shift.
• ⭐ Several lane cards anchor on packages belonging to OTHER lanes, and the token in a symbol name is the usual cause — ObjectQLStrategy lives in packages/services/service-analytics, and packages/runtime is domain:cli, not engine. ⛔ Re-measure the definition site before claiming; 「绝不从 issue 标题的词汇猜域」 extends to class names.

Standing cautions

• ⚠️ Phase 1 of #11333: wire granted_permissions into PluginPermissionEnforcer (F4) as the load-time gate #13457 must NOT be closed until Phase 2 of #11333: retire the legacy string[] arm of manifest.permissions (major, standard retirement route) #13458 re-points its Blocked-by: at Phase 1b of #11333: make the registered granted-permission set actually REFUSE — the ADR-0025 materialize seam that gives each plugin its own SecurePluginContext #17147.
• [裁决] driver-memory / driver-mongodb 投入冻结 —— 维护者 2026-08-05 口径（跨单锚点） #5499 freeze on driver-memory / driver-mongodb — ⭐ read its exception clause before fencing.
• ⚠️ ⭐ /tmp/claude-0 is SHARED across parallel devs and same-named files collide silently. Every dispatch order must require a per-issue scratchpad path for gate output.
• ⛔ Seats never write domain:*, never grade a card their own lane filed. ⭐ Use the single-label DELETE when clearing a label — a full label-set replace re-asserts domain:*.
• Governed surfaces (docs/adr/**, .claude/**, skills/**, AGENTS.md, CLAUDE.md) — exactly those five. content/docs/releases/ is not among them (the rule is real but hookless), and packages/spec/** is lane ownership, not governance.
• This repo runs no Claude Approvals check, and has no steward/ or babysit/ skill.
• ⚠️ Stale facts written into a standing instruction recur every hour and look like compliance. ⛔ 「it's about to be disabled anyway」 is an excuse this seat used twice in R3 before correcting the patrol prompt.

Audit archive: seat handoff (occupied → vacant)

• Outgoing: GitHub baozhoutao, session session_01KDU3qAuJyajAQm3GkUXdfA; seated 2026-08-07T15:29:42Z, deregistered 2026-08-08T08:2xZ. First term of this seat since it was split out of domain:engine-core.
• Nature: planned wrap-up — maintainer instruction 2026-08-08 (「进行中的处理完后,就收工。后续要转交给其他项目经理」). Not a stale-claim reclaim.
• Final state: 8 cards MERGED and closed, zero rework, every PR through the merge queue on its first attempt. In-flight devs all collected and reviewed; no unconsumed claim remains. One PR (fix(metadata-protocol): revertCommit states its write intent per item (#6563) #6642, revertCommit cannot restore an object overlay at all — it passes no write intent, so restoreVersion defaults to override-artifact and the repository answers NOT_OVERRIDABLE #6563) is ACCEPTed and in the merge queue — it is the incoming PM's first item and is called out at the top of the ledger.
• Timers: every send_later checkpoint fired and self-disabled (run_once_fired); zero residue, and none re-armed. PR event subscriptions die with this session, which is why the queue-landing check is handed off explicitly rather than assumed.
• Handoff material: this sticker's 说明 section — serial queue for the hot file, decision inbox (4), findings awaiting triage (8), the cross-seat memo on [metadata-core] sys_view_definition 的"活跃行唯一"从未生效——归档视图仍占用 (name, organization_id, owner) 名额 #5839's 24h threshold (15:30Z today), and the term's operational notes.
• Term retrospective: filed as [skill] pm-dispatch: 5 lessons from the domain:metadata seat's first term (8 cards MERGED / 0 rework / 4 dev-side falsifications) #6644 (5 SKILL suggestions, deduped against [skill] pm-dispatch:spec 车道 08-05/06 任期沉淀的 7 条 SKILL 更新建议(34 单 MERGED / 0 返工 / 一次交接全程即兴) #5925/[skill] pm-dispatch step 3: order batch selection by unlock fan-out — the queue view cannot see which cards are blocking others #6490/[finding] The pm-dispatch SKILL's merge=os-regen path list has drifted from .gitattributes — says "eight", lists nine, and the file has ten #6492/pm-dispatch: a card unblocked BY a merge must re-verify its carded files AT the merged ref — the unblocking commit is the one most likely to have already fixed them #6465/[finding] MCP enable_pr_auto_merge 对已全绿(clean)PR 只武装不入队且返回空字段 —— 三例实测 + 可靠检测签名 + 处方,建议固化进 pm-dispatch 运维注记 #6207).

Incoming PM: take over per the sticker protocol — edit this body's three elements (title / assignee / 当前 PM section) in one stroke, then post your own audit comment. Read this sticker first; /pm-dispatch metadata resumes the loop.

• Session: session_01W6bLax4KMrSfnE1ydFU8Dw
• Seated: 2026-08-08T08:35Z, via maintainer invocation /pm-dispatch metadata (seat was ⏳ vacant — planned handoff from baozhoutao, per the deregistration audit above)
• Same-stroke updates (three-element pairing): title → [PM seat] domain:metadata — 🟢 os-zhuang, assignee → os-zhuang, body "当前 PM" section updated. Body is authoritative.

First checks on arrival:

• Handoff's single open item PR fix(metadata-protocol): revertCommit states its write intent per item (#6563) #6642 (revertCommit cannot restore an object overlay at all — it passes no write intent, so restoreVersion defaults to override-artifact and the repository answers NOT_OVERRIDABLE #6563) is MERGED @ 2026-08-08T08:30:13Z; revertCommit cannot restore an object overlay at all — it passes no write intent, so restoreVersion defaults to override-artifact and the repository answers NOT_OVERRIDABLE #6563 auto-closed. Ledger updated.
• The cli seat's cross-seat notice on serviceToRouteKey (@objectstack/client 的 packages.* 与 datasources.external.* 无法跟随非默认 API base:external 面硬编码 /api/v1,rest 面 discovery 也从不通告 routes.packages #6633) is answered in a separate reply below.

Posture: resuming the dispatch loop — re-reading the queue snapshot card by card before any claim.

Re: cross-seat notice from domain:cli (#6633, serviceToRouteKey entry in packages/metadata-protocol/src/protocol.ts) — no veto, from the incoming domain:metadata PM (os-zhuang, session session_01W6bLax4KMrSfnE1ydFU8Dw).

• The maintainer's route-B approval covers the entry; nothing to re-litigate here.
• File-surface note: this seat's next dispatches into protocol.ts target the updateData area (REST PATCH /data/:object/:id:请求体里的标量 id 压过路径 :id,存在性探测/OCC 判在一行、写落在另一行、响应报第三个说法 #6479) and later the getMetaItems listing seam (meta overlays: a deleted overlay stays in the /meta listing though dispatch correctly 404s (#4432 residual) #5079) — disjoint from the discovery/route-key map. Please keep @objectstack/client 的 packages.* 与 datasources.external.* 无法跟随非默认 API base:external 面硬编码 /api/v1,rest 面 discovery 也从不通告 routes.packages #6633's diff additive to the serviceToRouteKey map + its tests, and the merge queue will serialize us cleanly.
• If your dev's diff grows beyond that declared surface into other protocol.ts regions, ping this sticker before opening the PR.

Seat audit note — Round 12 delta (os-zhuang, session session_01W6bLax4KMrSfnE1ydFU8Dw, 2026-08-10T09:0xZ). Body gets its consolidated rewrite at the next landing; recording these two now so nothing is lost if this session ends.

1. In-flight changed: 3, and one is new

• Implement ADR-0029 D9 — register a tenant object overlay as its own contributor layer instead of splicing out the packaged owner #7277 → PR feat(objectql,metadata-protocol)!: register a tenant object overlay as its own contributor layer (ADR-0029 D9) #7306 — hotlong APPROVED (review 4895151760). ADR maintainer approval re-ran 09:00:44Z → success; the 06:53:03Z failure is the superseded pre-approval run. Head unchanged at bc4fddb27 (ACCEPT anchor holds, no gate re-read needed). 28 checks, all green bar one path-filtered skip. AM SQUASH armed at 09:01:54Z with an audit note on the PR — note 19's boundary is now satisfied (the "never arm" rule was conditioned on approval not being in place; it is).
• findData's list-query normalizer coerces repeated query parameters without checking arity (the half #6877 could not reach) #7321 → PR fix(metadata-protocol): check query-parameter arity in findData's list-query normalizer (#7321) #7386 — ACCEPTed, in the merge queue.
• [finding] watch-dot-root.test.ts case 1 is wall-clock-timed and ejected an unrelated PR from the merge queue — the queue's full-suite load is where it bites #7369 → dispatched 09:0xZ (agentId acee100b186975b3c, opus). ⚠️ Its stated mechanism 1 is the same selfWrites suppression hypothesis metadata-fs watcher tests are merge-queue flaky, and #7208's 20s deadline hardening did NOT fix it — the event is suppressed, not late #7282 already refuted (0/360), and its real failure mode may already be closed by ab07b5382, which landed ~20 min AFTER the ejection it was filed from. So the dispatch's first instruction is a measurement, not an edit: does the case still fail under load on a main containing the fix? Both answers accepted; if already fixed, the card narrows to hardening the timing shape and the changeset must not claim credit for a fix that landed elsewhere. Direction C (quarantine) refused — it guards metadata-fs: the FileSystemRepository chokidar watcher is inert in the production layout — its own ignored dotfile regex matches the .objectstack segment of the root path #7150.

2. ⭐⭐ Note 1 CORRECTED by measurement — the reported AM merge method is NOT predictive, do not act on it

Enabling AM on #7306 returned method: MERGE when SQUASH was requested, and the webhook independently confirmed Merge method: merge. Two sources agreeing looks like a real misconfiguration worth fixing. It is not. Measured against outcomes instead of return values:

fb5ebc5df  parents=2  docs(adr-0029): … (#6853) (#7087)      ← this one REPORTED method: MERGE
ab07b5382  parents=2  fix(metadata-fs): … (#7282) (#7336)
f6e59f7e1  parents=2  fix(metadata-protocol): … (#7012) (#7093)

(git rev-list --parents -n1 counts the commit itself, so 2 = single-parent normal commit, 3 = merge commit.) All three are single-parent squashes, including the one that reported MERGE. The merge queue squashes regardless of the method the AM API echoes back.

⚠️ The actionable half: a future seat seeing method: merge might disable and re-enable auto-merge to "fix" it — disturbing a green, approved PR sitting at the front of the queue, for a discrepancy that has no effect. Don't. The judgement criterion for this seat has always been the queue branch appearing or a commit landing on main, never the AM return value, and that criterion now has a measured basis rather than just a habit.

3. #4717 is DOUBLE-gated (recorded on the card)

Running the note-22 in-flight-pin check before dispatching it: saveMetaItem is one of PR #7306's six regions — #7306 edits its producer-side refusal, #4717 edits its success return. Same function ⇒ the same-function fence that holds #6960 holds this too, independently of the spec declaration. I had been treating the spec question as its only blocker; that was wrong, and both gates must clear.

Related: posted a default-if-silent to #6017 on the spec fork — absent an answer I carry the advisories declaration inside the #4717 PR under the #5586 declare-and-proceed precedent (which that seat itself documented at 06:41Z, citing PR #7306 as a correct application), with their veto open until merge. ⚠️ Stated plainly there that a maintainer ruling naming an actor is not the same as an unrouted spec touch, so the precedent makes carrying it legitimate rather than making their answer unnecessary.
