[finding] the authorable-key deletion gate's reachability BFS reports integration/DataSyncConfig unreachable from the metadata-type roots — it is two hops from the connector root, so #4650 proof 2 waives a tombstone for a key a stack manifest really authors

What is wrong

computeSurfaceReachability() in packages/spec/scripts/build-schemas.ts is the whole of check (c) proof 2 (#4650, 2026-08-02 ruling): a deleted authorable-surface/ baseline line is legitimate when "the def is not reachable from the metadata-type roots (no metadata document is ever parsed by it), so its entry was over-collection and there is no author to tombstone for."

For integration/DataSyncConfig that answer is measurably false. The def sits two hops from a root the same file enumerates, and the runtime really does parse metadata documents against it.

The function's own docblock names this direction as the dangerous one:

Judged conservatively: one shared entry marks the whole def reachable — a false "reachable" demands a tombstone too many, a false "unreachable" would waive one silently.

This is that false "unreachable", in the tree, today.

The two readings, side by side

Reading A — what the gate says. pnpm --filter @objectstack/spec gen:schema on a branch that bare-deletes integration/DataSyncConfig:schedule, exit 0, printing:

ℹ️  4 baseline deletion(s) since cca1dc0bfb1e carry their own proof (#4650):
     - integration/DataSyncConfig:schedule — def not reachable from the 26 metadata-type roots
       (BUILTIN_METADATA_TYPE_SCHEMAS + EXTRA_METADATA_TYPE_SCHEMAS overlay; BFS over this
       build's in-memory Zod graph): an over-collected entry, never parsed against a
       metadata document.

Reading B — what the graph actually holds. A tsx probe over the same modules the build imports, run with OS_EAGER_SCHEMAS=1 exactly as gen:schema does:

roots: 26
connector root === DeclarativeConnectorEntrySchema: true
connector root type tag: object
unwrap trail: object
shape keys sample: name,label,type,description,icon,authentication,provider,providerConfig
has syncConfig prop: true
syncConfig unwrap: optional -> object
syncConfig inner === DataSyncConfigSchema: true

So: getMetadataTypeSchema('connector') (an EXTRA_METADATA_TYPE_SCHEMAS entry, one of the 26 roots the message counts) resolves to an object whose syncConfig property, unwrapped through one optional, is the same instance as the exported DataSyncConfigSchema. reachableVia('integration/DataSyncConfig') should answer root-graph; it answers null.

Reading C — the runtime agrees with B, not A. Pin tests in packages/spec/src/cron-typed-positions-retirement.test.ts parse a connector through three doors and observe syncConfig being processed by that def each time: the bare ConnectorSchema, DeclarativeConnectorEntrySchema, and ObjectStackSchema with connectors: [...] — i.e. a real defineStack manifest, and PUT /api/v1/meta/connector/:name behind getMetadataTypeSchema. A metadata document IS parsed by this def.

Why it matters

Proof 2 exists to waive the tombstone requirement only where no author can receive a prescription. Where it answers falsely, the gate lets an authorable key be deleted from a non-strict schema with no tombstone and no ADR-0087 entry — which is precisely the silent-strip class ADR-0104 and #3733 name: the author keeps writing the key, gets a clean parse, and the setting never takes effect. Every gate stays green, repo-wide, for exactly the shape check (a) refuses in its own failure text.

The blast radius is not one key: any def reachable only through the same shape of edge is equally invisible, so the waiver is available to every future spec retirement that touches one.

Repro

On a branch off main, delete the schedule key from DataSyncConfigSchema in packages/spec/src/integration/connector.zod.ts (no retiredKey(), no registry entry).
Delete the line "integration/DataSyncConfig:schedule" from packages/spec/authorable-surface/integration.json.
pnpm --filter @objectstack/spec gen:schema — exits 0 and prints the proof-2 line quoted above.

Where to look

packages/spec/scripts/build-schemas.ts:

computeSurfaceReachability() — the BFS, zodChildSchemas(node) and the bridged map;
zodByDefKey — whether the instance it holds for integration/DataSyncConfig is the instance the connector shape holds (the probe shows the EXPORTED schema is; the def-key map may hold another);
zodShapeOf(node) for the connector root and for the optional wrapper on syncConfig.

Not diagnosed here on purpose — two independent candidates (an edge the child-walk does not follow, or a def-key map keyed on a different instance) and only one of them is the fault. This card names the contradiction and the reading that settles it.

Not in this card's scope

⛔ Nothing here argues that the four deletions on the branch above should be reverted; that route is a maintainer ruling and stands on its own. What is asked here is that proof 2 stop answering null for a def a manifest parses.

Suggested acceptance

a --self-test case that fails when a def reachable through an optional-wrapped property of an EXTRA_METADATA_TYPE_SCHEMAS root reads null;
reachableVia('integration/DataSyncConfig') answers root-graph on main;
the fix does not turn the conservatism around: a genuinely unreachable def still reads null, pinned with its own case.

Root cause: it is neither of the two candidates this card named — it is ROOT ENUMERATION

This card deliberately left the diagnosis open between "an edge the child-walk does not follow" and "a def-key map keyed on a different instance". Measured at 1504dd1d77 (the head this card was filed against), it is neither. The BFS follows the edge correctly and the def-key map is fine. connector is not one of the roots the BFS starts from.

The measurement

computeSurfaceReachability() builds its root set from listMetadataTypeSchemaTypes() (build-schemas.ts, the for (const type of listMetadataTypeSchemaTypes()) loop). That function (packages/spec/src/kernel/metadata-type-schemas.ts) unions BUILTIN_METADATA_TYPE_SCHEMAS with the EXTRA_METADATA_TYPE_SCHEMAS overlay and deliberately does not enumerate UNREGISTERED_KIND_SCHEMAS — the comment immediately below it says so in as many words, per #6245: that list is the REGISTERED METADATA TYPE set and enrolling these entries "would claim a status this change is careful not to grant".

connector lives in UNREGISTERED_KIND_SCHEMAS. So getMetadataTypeSchema('connector') resolves (it reads that map as its third fallback) while listMetadataTypeSchemaTypes() never names it — and the gate's roots come from the second function, not the first.

Probe over the same modules the build imports, OS_EAGER_SCHEMAS=1, exactly as gen:schema runs:

roots count = 26 | includes connector = false | includes webhook = false | includes sharing_rule = false
listUnregisteredKindSchemaTypes() = ["analytics_cube","connector","sharing_rule","webhook"]
IDENTITY GUARD root === DeclarativeConnectorEntrySchema = true
ALL-ROOTS closure = 5420
ALL-ROOTS reaches DataSyncConfigSchema = false
CONTROL ALL-ROOTS reaches ObjectSchema = true
CONNECTOR-ROOT closure = 438
CONNECTOR-ROOT reaches DataSyncConfigSchema = true
CONNECTOR-ROOT reaches ConnectorSchema = true
syncConfig unwrap trail = optional | inner === DataSyncConfigSchema = true

Read it as three facts:

The edge is fine. From the connector root the repo's own zodChildSchemas walk reaches DataSyncConfigSchema — a 438-node closure, and the syncConfig property unwraps through exactly one optional to the very instance the module exports. Reading B in the card body reproduces.
The map is fine. The instance the connector shape holds IS the exported DataSyncConfigSchema; there is no second instance to be keyed on.
The root set is the fault. The 26-root closure is 5420 nodes and does not contain it, while the positive control (ObjectSchema, a def nobody disputes) is in that same closure. Nothing is wrong downstream of a root that was never a root.

Why that makes the gate's own docblock false

computeSurfaceReachability()'s docblock says its roots are "BUILTIN_METADATA_TYPE_SCHEMAS plus the EXTRA_METADATA_TYPE_SCHEMAS overlay (both behind listMetadataTypeSchemaTypes / getMetadataTypeSchema), i.e. the schemas a metadata document is actually parsed against". The two halves of that sentence are not the same set. PUT /api/v1/meta/connector/:name and stack.connectors[] both parse a metadata document against an unenumerated root, so the "i.e." is where the false "unreachable" enters. Same for webhook, sharing_rule and analytics_cube and anything reachable only through them.

⇒ The fix belongs at the root set (or at the docblock's claim), not at zodChildSchemas and not at zodByDefKey. A --self-test case shaped as this card suggests — "a def reachable through an optional-wrapped property of a root" — would pass today against a BUILTIN root and still not catch this, because the property walk is not what is broken.

Two notes for whoever takes this

⚠️ A harness trap that produces a false negative on exactly this question. Under tsx, packages/spec sources load as CommonJS (the package declares no "type": "module"), and a static ESM import of these modules from an .mts probe yields a SECOND instance: with static imports the same probe answers root === DeclarativeConnectorEntrySchema false and CONNECTOR-ROOT reaches DataSyncConfigSchema false — i.e. it reproduces the bug's signature for a reason that has nothing to do with the bug. Dynamic await import() for every module gives one instance and the readings above. Any probe here needs the identity guard line in its output, or its zeroes mean nothing.
Small correction to this file's prose, worth folding into the fix. listUnregisteredKindSchemaTypes()'s docblock says the map holds "today webhook / connector / sharing_rule / theme / analytics_cube (meta: bind Zod schemas for webhook / connector / sharing_rule WITHOUT registering the kinds — close the unvalidated PUT /meta write hole (#2657 audit, option A) #6245 the first three, theme and analytics_cube have strict stack schemas but no UNREGISTERED_KIND_SCHEMAS binding — PUT /meta/theme/:name still accepts any JSON (the two doors #6245 left open) #10194 the last two)" — five. The map holds four: theme left at defineStack({ themes }) is parsed, ingested and never applied — the last hop from a stored theme item to the theme engine does not exist #10485 when ThemeSchema was retired, and the code comment at the removal site records that, but the docblock above still counts it. Not filed separately; it is one line in the file this fix touches.

Measured on objectstack-ai/objectstack, branch claude/issue-16320-retire-cron-typed-positions, at 1504dd1d77e9b0e0c53dd6fb4251c0874e1e5b7e. ⛔ Nothing here asks for the four deletions on that branch to be reverted, and this comment changes no label and no state on this card.

Why this is dispatchable without a ruling

The direction is 「恢复不变量」, a named non-escalating class: the gate's own docblock states the conservative direction it guarantees — 「a false "unreachable" would waive one silently」 — and the tree contains exactly that false unreachable. Restoring a stated invariant is the seat's call, ⛔ not the maintainer's.

The diagnosis is already measured — ⛔ do not re-derive it

os-bill's comment 5616358457 closed the card's open question with a probe over the same modules the build imports. It is neither candidate the card body offered: the child-walk edge is fine and the def-key map is fine. The root set is the fault — connector is simply not one of the 26 roots the BFS starts from.

⚠️ And that exclusion is deliberate, which is the whole difficulty of this card. listMetadataTypeSchemaTypes() unions BUILTIN_METADATA_TYPE_SCHEMAS with the EXTRA_METADATA_TYPE_SCHEMAS overlay and pointedly does not enumerate UNREGISTERED_KIND_SCHEMAS; the comment below it says, per #6245, that enrolling those entries 「would claim a status this change is careful not to grant」. connector lives in that list.

⇒ this card is NOT "add connector to listMetadataTypeSchemaTypes()". That spelling would reverse #6245 and grant registered-metadata-type status to four kinds a previous change deliberately withheld it from. The two questions are genuinely different and the gate conflated them:

「is this a registered metadata type?」 — what listMetadataTypeSchemaTypes() answers, and it is answering correctly.
「is there an author who could be authoring against this def?」 — what a reachability root set needs, and for that question the unregistered kinds are authored documents too.

The fix belongs at the gate's root enumeration, ⛔ not in the kernel's registration vocabulary.

Acceptance, as the card and comment already fix it

reachableVia('integration/DataSyncConfig') answers a root-graph hit rather than null.
A bare deletion of integration/DataSyncConfig:schedule from the authorable-surface/ baseline is no longer waived by check (c) proof 2 — that is the user-visible point of the whole card.
The positive control stays put: ObjectSchema and the other 26-root defs remain reachable (the comment measured that closure at 5420 nodes).
#6245's guarantee is untouched — whatever the fix does, listMetadataTypeSchemaTypes() must still not enumerate the unregistered kinds.

"tests": "IMPLEMENTATION, measured. (1) Defect reproduced on my head before any edit: probe over the modules the build imports, OS_EAGER_SCHEMAS=1, dynamic imports, identity guard printed -- roots=26, includes connector=false, listUnregisteredKindSchemaTypes()=[analytics_cube,connector,sharing_rule,webhook], IDENTITY GUARD root === DeclarativeConnectorEntrySchema=true. (2) Waiver demonstrated BOTH WAYS on the real tree, not asserted. The card's literal repro key (DataSyncConfig:schedule) already landed on main with #16320, so the demo deletes a live sibling key under the same def (timestampField) from the schema AND from authorable-surface/integration.json -- the gate judges the DEF half of the key, so it is the identical code path. BEFORE (ca78860): check:authorable-surface exit 0, gen:schema exit 0, printing 'integration/DataSyncConfig:timestampField -- def not reachable from the 26 metadata-type roots'. AFTER: both exit 1, printing '-- def reachable from the metadata-type roots; the entry at ca78860 was LIVE (never tombstoned).' Exit codes captured before any pipe. Both legs restored with 'git checkout HEAD --', proven by git hash-object equal to the HEAD blob and an empty git diff HEAD. (3) ABLATION: reachabilityRootTypes() swapped back to listMetadataTypeSchemaTypes() at the one call site. On-disk proof first -- anchor counts 1->0 on the fixed spelling and 0->1 on the ablated one; the gate is executed by tsx FROM SOURCE (the test sandbox copies scripts/ per run) so there is no dist between the edit and the run, which is the whole of the reach-the-consumer step here. New pin then goes RED on expect(status).toBe(1) receiving 0 -- the deletion is waived again. Restored, hash-verified, trap-guarded. (4) TESTS: pnpm --filter @objectstack/spec exec vitest run --project repo scripts/build-schemas-check-mode.test.ts -- 75 passed (75), run twice, on c548dea and again on the merged head 00ac98d. Note the file is in the 'repo' vitest project, not 'local'. pnpm --filter @objectstack/spec typecheck :: exit 0. pnpm --filter @objectstack/spec build :: exit 0 on the merged head, working tree clean. (5) NEW PIN reads both regimes off ONE seeded state: with OS_EAGER_SCHEMAS=1 (how gen:schema actually runs, and the only regime where reachableVia() can answer 'root-graph' at all) and without it (lazySchema hands back a Proxy, zodByDefKey holds the Proxy while the walk visits the resolved target, and the same verdict arrives through the derived-clone bridge). Either direction alone is satisfiable by a gate that is simply wrong in the other, so both are asserted together. A beforeAll fixture guard asserts connector is still absent from listMetadataTypeSchemaTypes() and present in listUnregisteredKindSchemaTypes() -- that is acceptance 4, stated where it fails. BLOCKER EVIDENCE. (6) gen:schema CANNOT restore the two lines -- the PM's named route, tested rather than assumed. In DataSyncConfigSchema the count of a 'schedule:' property is 0; in MetricSchema the count of a 'filters:' property is 0 (both were deleted from the Zod source). Baseline counts BEFORE: DataSyncConfig:schedule=0, data/Metric:filters=0, lit controls DataSyncConfig:batchSize=1 and data/Metric:label=1. Ran 'pnpm --filter @objectstack/spec gen:schema' :: exit 0. AFTER: identical -- both still 0, both lit controls still 1, and git status --porcelain EMPTY (gen:schema wrote nothing at all). The authorable surface is generated from the keys the build EMITS; reachability decides whether a DELETION is waived, it never adds a key back. (7) The CI red reproduced locally by derivation rather than by re-running CI's arm: the committed anchor authorable-surface.base.json is pinned at baseRev 53ef057 with 7836 keys against 7784 live, i.e. 927 keys deleted since the anchor. Of those 927, 921 have a def the build no longer emits (the manifest ratchet's branch, untouched by this fix) and 6 reach the reachability branch. Of those 6, exactly TWO flip waived->refused under the new roots: data/Metric:filters and integration/DataSyncConfig:schedule. The other four (automation/ScheduleState:cronExpression, kernel/HotReloadConfig:distributedConfig, system/BackupConfig:schedule, system/CacheWarmup:schedule) stay null in both root sets. That is exactly the two keys the PM measured on Build Core, derived independently. (8) REACHABILITY PATH PRINTED for each of the two, as asked, with the gate's own zodChildSchemas walk and the identity guard true: DataSyncConfigSchema -- root 'connector' .syncConfig -- 2 hops. MetricSchema -- root 'analytics_cube' .measures -- 2 hops. Both are genuine authoring doors (stack.connectors[] / stack.analyticsCubes[] and PUT /api/v1/meta/:type/:name). NOT over-reach. (9) The re-anchor route probed and RESTORED: 'pnpm --filter @objectstack/spec gen:authorable-surface-base' :: exit 1, refusing with '--update-base cannot establish which way authorable-surface.base.json would move (#5370)'. That is the gate failing closed on a truncated history, not a verdict on the route: this checkout is shallow (71 commits visible on origin/main) and 53ef057 lies outside that window. Two-legged ancestry probe: 'merge-base --is-ancestor 53ef057 origin/main' exit 1, control leg (ca78860, known in origin/main history) exit 0 -- but the control is NOT at least as deep as the tested commit, so the negative is NOT MEASURED, not a negative.

I did NOT take it unilaterally for two reasons: the card itself places the disposition of the already-landed deletions outside its scope ('that route is a maintainer ruling and stands on its own'), and advancing a gate's own baseline inside the PR that changes that gate is exactly the shape a reviewer should distrust, so it should be an explicit instruction rather than my choice. Say the word and it is one command plus one commit; note it must be run in a checkout deep enough for #5370 to establish the anchor's ancestry, which this container is not."

⚖️ 转入决策箱 —— 修复已完成并推送,卡在一件本卡范围之外的事

PM 席位 session_014DBGjJFyndTj766aReCL2g,2026-09-14T05:3xZ。pm:dispatched → needs-user-decision(一笔写入,回读匹配)。
Release: 会话 session_014DBGjJFyndTj766aReCL2g · 因 = 需维护者裁决 · 去向 = 决策箱;assignee 已清,PR #18131 留 draft。

维护者速读

改了什么:门禁算「这个字段还有没有人在写」的时候,起点名单漏了四类元数据(connector / analytics_cube / sharing_rule / webhook)。漏掉的后果是:有人把一个真的有人在写的字段从台账里删掉,门禁会以为「反正没人用」而放行。修复把起点补全。实测:17 个 def 从「可被静默删除」变回「受保护」。

为什么改:这正是 #4650 当初设这道门要防的事,而它已经漏过去了。

卡在哪:门禁一修好,立刻抓到两笔早就发生的删除 —— DataSyncConfig:schedule 和 Metric:filters。它们不是事故,是两笔有裁决、已完成的退役(一笔还是您 2026-09-10 亲自裁的)。问题是:这两个 key 在代码里已经彻底不存在了,没有任何办法把台账那两行"恢复"回去,而门禁又要求删除必须带证明。于是构建红着。

风险与代价(含回滚):推荐的 A 是一条命令 + 一次独立提交,把门禁的基准台账推进到现状(它已经落后 927 个 key)。它不削弱任何东西 —— 以后的删除照样要证明。代价是:它等于一次性认了那 927 个 key 的删除都不欠墓碑。回滚 = revert 那一个提交。

席位意见:A(本 PR 内,独立提交)+ 把 C 另立一张卡。理由见下面四棱。⚠️ 一个诚实的提醒:A 在本容器里没验成 —— 浅 clone 下 --update-base 按 #5370 拒绝执行,因为它确立不了基准的祖先关系。它预期在完整 clone 下可用,但这一点没有被测量。

你要做的(一个动作):选 A / B / C / D。

四棱

① 实际业务需求 —— 修复挡住的是真实伤害:17 个 def 目前可被静默删除,实测不是推演。而阻塞它的是记账:基准台账落后 927 个 key。至于那两个 key 本身,没有任何人在写它们 —— 两笔退役的源码注释都逐字记着 ZERO consumers(filters 从来没有策略读过,schedule 在 packages/spec 外没有读者)。⇒ A 服务真实需求;B 为没人用的 key 发明工作;D 让 17 个 def 继续裸奔。

② 项目长远合理性 —— C 是唯一修结构而非修个案的:今天一笔走 guidance 路线完成的退役,在一个可达的 def 上根本没有任何证明形状可用,它一直过关只是因为 proof 2 是坏的。契约优先的做法是让每条合法退役路线都有对应的证明。但 C 单独不解 schedule(它按裁决压根没走任何路线)。⇒ A 解现在,C 补结构,两者是配对不是二选一。

③ 防 AI 写错 —— 这道门存在的意义就是拦静默删除。D 在这一棱上最差:它留着坏掉的豁免,而那正是「声明了却静默失效」的典型形态。C 在这一棱上最强:它让 guidance 退役必须产出机器可查的证明,AI 想省略就会响。A 中性 —— 它重新对齐基准,未来的删除照判。

④ 创业阶段不扩散 —— B 最贵,且对 schedule 而言等于推翻一条已记录的维护者裁决(源码逐字:「maintainer ruling 2026-09-10 on the retirement PR」,刻意不留 tombstone / D2 / D3)。⇒ 排除 B。A 是一条命令加一次提交;C 是一张边界清楚的独立卡。

⇒ 四棱同向指往 A + C,分歧只在 A 与 C 的先后。但 ⛔ 这不进代裁通道:A 一次性处置 927 个 key 的墓碑问题,且「在改这道门的 PR 里推进这道门自己的基准」正是复核人应当怀疑的形状。这一笔要维护者亲自说。

选项

	做法	代价
A(荐)	`gen:authorable-surface-base` 推进基准,作为本 PR 内独立的、可复核的一次提交	一次性认下那 927 个 key 不欠墓碑。⚠️ 可用性未测量(浅 clone 拒绝)
B	给两个 key 各补一条完整退役路线,各自立卡、先于本卡落地	远超本卡范围;对 `schedule` 等于推翻已记录裁决
C	给 check (c) 加第四条证明,让 guidance 路线能自证	修结构,但单独不解 `schedule`;明确是另一张卡
D	什么都不落	缺陷与它的 pin 都不合入,坏豁免继续在 17 个 def 上放行删除

交付物现状(已实测,⛔ 不是自述)

修复已实现、已 pin、已推送;head 00ac98d0,已并入 origin/main。验收 1/3/4 绿且钉死;listMetadataTypeSchemaTypes() 未被改动,meta: bind Zod schemas for webhook / connector / sharing_rule WITHOUT registering the kinds — close the unvalidated PUT /meta write hole (#2657 audit, option A) #6245 的保证仍成立。
两个 key 的可达路径印出来了(不是推断):DataSyncConfigSchema ← root connector .syncConfig,2 跳;MetricSchema ← root analytics_cube .measures,2 跳。两条都是真实的写入门。⇒ 不是 widening 过头。
席位独立复核了本卡最承重的一条:DataSyncConfigSchema(connector.zod.ts:238)没有 schedule: 属性;MetricSchema 的 filters 只存在于拒收断言与注释里。⇒ 「用 gen:schema 恢复」这条路线机械上不可能 —— 那是 PM 给的路线,dev 测了,是错的。
⭐ 该路线当初是带着显式停止条件下发的(「若重生成没有恢复那两行,就停下报 needs_decision」)。dev 照做了。机制假设写成可证伪的,就是为这一刻准备的。

Ruling: batch #135 item 3 · letter A (+ C as its own card) · maintainer 「135 同意」 2026-09-15T15:01Z

Director seat, session session_01WCEaPsmKY4UyoivKkkaUHt. Presented on 2026-09-15 with this seat's own recommendation A in this PR as a separate commit, plus C filed as its own card; the maintainer's one-line reply adopts it. The 927-key anchor question this seat declined to self-adjudicate is thereby the maintainer's ruling.

What is ruled

A — PR fix(spec): the authorable-surface reachability roots include the unregistered kind schemas #18131 gains a second, separate commit that advances the committed anchor with pnpm --filter @objectstack/spec gen:authorable-surface-base, run in a full (non-shallow) clone; the PR body quotes this ruling (「135 同意」 on batch 🔗 Broken links detected in documentation #135 item 3, presented as 「A 本 PR 内独立提交 + C 另立卡」). Advancing the anchor is the deliberate maintenance act the build's own output names; it forgives no future deletion.
B is refused: for integration/DataSyncConfig:schedule it would reverse the maintainer's 2026-09-10 retirement ruling recorded in the source.
C is filed: check (c) has no proof shape for a guidance-route retirement on a reachable def — add a fourth proof so UNKNOWN_KEY_GUIDANCE retirements prove themselves (batch #135 item 3, C) #18301 — check (c) gains a fourth proof so a guidance-route retirement on a reachable def proves itself; data/Metric:filters is its specimen.
D is refused.

Execution

needs-user-decision → pm:queue, domain:spec, no assignee; the lane seat re-dispatches on the existing branch claude/issue-17356-reachability-root-enumeration / PR #18131 (still draft, head 00ac98d0). If --update-base refuses in the dev's environment (shallow clone, #5370), the dev reports back rather than working around it, and #18301 runs first. Acceptance 2 of the original dispatch (a bare deletion of a reachable key is no longer waived) is measured on the advanced anchor.

Prior rulings read: integration,datasyncconfig,connector,authorable-key,deletion,gate,reachability,reports,unreachable,metadata-type,roots,hops (+7 more) → 85 hits; ADR-0076 D10/D12, ADR-0110 D3, ADR-0120 D5, ADR-0124 D3, ADR-0129 D2, ADR-0130 D4 — none governs this card; #4650 (proof 2) and the 2026-09-10 retirement ruling on #16320 are the governing rulings.

Generated by Claude Code

✅ Letter A landed — PR #18485 merged. ⛔ This card stays OPEN; letters B/C and PR #18131 remain.

domain:spec execution seat, session_01KB5PFtxuy1x3dcR5gxudx6, 2026-09-16T16:38Z. Verified by content on origin/main, ⛔ not by the API's merged field.

reading	value
`origin/main` tip	`fed4a15ab5`, single parent `2f11e2db7b` ⇒ squash, as expected
subject on the tree	`chore(spec): advance the authorable-surface deletion-gate anchor to main tip (#17356 letter A) (#18485)`
the anchor's `baseRev` on main	`85c6d76ec42a879f219436eaa58bda06c68298b2` — exactly the merge base the ruling required
lit control	`ui/ObjectGanttProps` = 17 keys present (the family the review measured as newly arrived)
dark control	`zzbaseRevzz` = 0 (exit 1)
merge queue	empty

⭐ The ruling's untested inference is now settled on main, not just on a PR head: an anchor-only advance did not red the authorable-key deletion gate, and the anchor now equals main's live surface at that base.

⇒ The ruling's next step is unblocked, and it is this seat's

Ruling 5696910871, verbatim: 「letter A lands FIRST in its own anchor-only PR against main … Then PR #18131 merges main.」 ⇒ that is now actionable.

PR #18131 is open, draft, head dc98ee22a3, branch claude/issue-17356-reachability-root-enumeration, labels size/xl, tests, tooling, skip-changeset, needs:contract-review.

⚠️ The hazard on that merge, named now so nobody hand-resolves it

PR #18131 carries its own copy of packages/spec/authorable-surface.base.json at baseRev b9598e9c (992/1056), measured by the #18485 review. main now carries baseRev 85c6d76e. ⇒ both sides moved the same generated file.

⛔ That file must NOT be hand-merged, and the merge must NOT be taken on faith. .gitattributes routes paths of this kind to merge=os-regen, which merges with exit 0 and zero conflict markers while silently dropping one side — the failure mode leaves a plausible-looking tree and no signal at all.

Prescription for the round that takes it, ⛔ not optional:

Merge main through scripts/pm/os-regen-merge.sh, ⛔ never a bare git merge.
⛔ Never run a gen: script while the tree is in MERGE state — build-schemas.ts refuses --update-base mid-merge (os-regen 驱动指示的 gen:schema 在 merge 未 commit 时运行,会把 authorable-surface 锚点倒退回旧 merge-base —— 生成器写入、门全绿、静默撤销 main 的锚点推进 #5370), and a gen: run inside a merge is how a half-merged anchor gets blessed.
After the merge completes, regenerate the anchor on the new merge base and prove it byte-identical to what the generator produces there — ⛔ not a hand-reconciled union of the two keys[] arrays. The chore(spec): advance the authorable-surface deletion-gate anchor to main tip (#17356 letter A) #18485 review's method is the one to copy: regenerate in a clean worktree at the merge base, cmp against the committed file (expect exit 0), and carry two dark controls that must differ.
Re-read node scripts/pm/check-clause2-carriers.mjs --pair 18131 after any label or head move.

State

pm:dispatched and assignee os-warren unchanged — this card runs to MERGED and letter A was Part of, ⛔ not Fixes.

⏳ The #18131 round is queued behind the batch ceiling, which the maintainer set to 3 at 16:3xZ (「后续并发降到3」). Five dev rounds are in flight; this one fires when in-flight devs drop below 3. ⛔ Recorded on the card rather than held in session memory, because 「等待他座位也是状态,写在卡上才存在」.

Letter C (#18301, pm:queue, unassigned) stays serialized behind #18131, per the ruling. ⛔ Not claimed here.

▶️ The ruling's next step is dispatched — PR #18131 merges main. Recorded here because a dispatch without a card note is a half-state.

domain:spec execution seat, session_01KB5PFtxuy1x3dcR5gxudx6, 2026-09-16T17:00Z. ⛔ No new Claim: and ⛔ no label change: this card is already pm:dispatched with assignee os-warren, and this is a continuation round on the same card, not a new claim.

Ruling 5696910871, verbatim: 「letter A lands FIRST in its own anchor-only PR against main … Then PR #18131 merges main.」 Letter A landed 16:37Z.

⇒ both sides moved the same generated file. Verify-lock at dispatch: free, arrival depth 1.

⚠️ The hazard, and one thing added to the prescription that was NOT in the landing note

.gitattributes:**143** routes packages/spec/authorable-surface.base.json to merge=os-regen — measured, not recalled. Such a path merges with exit 0 and zero conflict markers while silently dropping one side, leaving a plausible tree and a clean git status.

The landing note already prescribed scripts/pm/os-regen-merge.sh, ⛔ never gen: mid-merge, and regeneration on the new merge base proven byte-identical with two differing dark controls.

⭐ Added at dispatch: .gitattributes's own header (~line 23) notes the driver has to be configured or these paths fall back. ⇒ 「I ran the wrapper script」 and 「the driver was live for this merge」 are two different readings, and the round is required to prove the second. ⛔ The first alone would let the silent drop through while looking like compliance.

Fences carried into the order

⛔ Letter B is refused by ruling — integration/DataSyncConfig:schedule must read 0 on the merged tree, with integration/DataSyncConfig: non-zero as its control.
⛔ Letter C (check (c) has no proof shape for a guidance-route retirement on a reachable def — add a fourth proof so UNKNOWN_KEY_GUIDANCE retirements prove themselves (batch #135 item 3, C) #18301) stays serialized behind; not touched.
⛔ The anchor prescription must not bleed onto build-schemas.ts and its check-mode test — those are this branch's actual subject and are not generated. Conflicts there are resolved normally and reported file by file.
⛔ needs:contract-review untouched by the dev (it is on both carriers, and it is the seat's). ⛔ No ready flip, no enqueue, no auto-merge.
Stop-and-report is pre-authorised for the one case that cannot be resolved honestly: if both sides changed the same logic in build-schemas.ts and picking either loses behaviour.

Concurrency

Dispatched into the free slot under the maintainer's 16:3xZ ruling 「后续并发降到3」 — three dev rounds now in flight (#17670 remediation, #18123 remediation, this one). ⇒ batch is at its cap; the next dev dispatch waits for a return.

Seat adjudication — the round's two open questions, and what the seat did

The merge-main step the ruling ordered ("letter A lands first in its own anchor-only PR; then PR #18131 merges main") is done: PR #18485 landed as squash fed4a15ab5, and this branch's merge brought it in — head advanced dc98ee22a3 → 251d76a2fb, mergeable flipped false → true. The round raised two questions; both are answered here, and one of them corrects the seat.

Q1 — the split carrier: A, and the seat has done it

The round measured, correctly, that needs:contract-review was on PR #18131 only and not on this card, which is why check-clause2-carriers.mjs --pair 18131 exited 4 on row C1. The seat's dispatch asserted it was on both carriers. That assertion was wrong, and the round was right to report it rather than act on it — the label is the seat's on both carriers, and the checker forbids a checker writing it.

Repaired at 2026-09-16T18:4xZ (18:45 read-back): needs:contract-review re-attached to this card, so the pair is whole again. The reasoning for A over B or C is the checker's own: the second carrier is the only machine-readable evidence that a gate was cleared rather than stripped, and a stripped gate reads downstream as a green light. C — leaving the split standing — is the one option that is actively unsafe, because the card can then be enqueued past a gate that is live one carrier over.

Q2 — re-merge to the current tip? A, with C as the landing-time fallback

The ruling asked for a merge of main once letter A landed, and 251d76a2fb is exactly that. origin/main has since moved (it read fed4a15ab5 when the merge ran; it is fb6b2c369e at 2026-09-16T18:45:52Z) — that is the normal state of any PR against a moving main, not a defect, and chasing it is unbounded. The anchor proof survives the move: baseRev 85c6d76e remains an ancestor of the newer tip.

So: no re-merge now. If the queue reports the branch behind at landing time, it is re-merged then, through scripts/pm/os-regen-merge.sh — ⛔ never by hand, and ⛔ never with a gen: script running mid-merge.

What happens next on this card

An isolated at-tier contract review of PR #18131 at head 251d76a2fb is running now. It is briefed to verify the two load-bearing history facts rather than accept them: that the merge=os-regen driver was genuinely live for the anchor (the driver can exit 0 with no conflict markers while silently dropping one side, and routing falls back silently when the driver is unconfigured), and that the refused letter B is genuinely absent from the branch, with a lit control proving the probe can see what it says is missing.

Two readings the seat is carrying into that review rather than asserting as facts:

CI on 251d76a2fb at 2026-09-16T17:47:47Z — latest run per check NAME, 35 names: 31 success, 4 skipped (Build Docs, Check Changeset, Console Pin Gate, Packed-tarball smoke (opt-in)), 0 failed, 0 in progress. All seven checks that were red on dc98ee22a3 are green here. A skipped lane is no verdict, not a green one — and Check Changeset is skipped because this PR carries skip-changeset, which is a claim, not a measurement. The reviewer decides whether the absence of a changeset is right for what the diff changes.
The round reported this container's .claude/agents/os-dev.md is stale against origin/main in exactly 7 line-regions and followed origin/main on every one, including the rule that the review gate label is the seat's. That matches the count the seat forecast, and it is the reason the round attached nothing.

PR #18131 squashed as 2882528786ee33c870a9c14ee0c4d81030250c76, which is origin/main's tip. Verification at 2026-09-16T20:07:25Z — read from the tree, ⛔ not from the API's merged field:

git merge-base --is-ancestor 2882528786 origin/main → exit 0.
Subject probe (lit): reachabilityRootTypes in packages/spec/scripts/build-schemas.ts → declared at :1187, called at :1217, with its docblock at :1197/:1199.
Lit control, same file: listMetadataTypeSchemaTypes → 5 lines, unchanged and still there — the fix widened the reachability roots without touching the registered-type list, which was acceptance 4.
Dark control: reachabilityRootTypesZZZ → exit 1.
The pin landed too: 17356 → 9 lines in packages/spec/scripts/build-schemas-check-mode.test.ts.

The card is closed by the squash and carries no pm:* state label.

The ruled sequence, completed

Ruling 5696910871 (甲) asked for three things in order, and all three are now settled:

Letter A first, alone — PR chore(spec): advance the authorable-surface deletion-gate anchor to main tip (#17356 letter A) #18485, one file, merged 16:37:10Z as fed4a15ab5. ✓
Then this PR merges main — through scripts/pm/os-regen-merge.sh, merge 59c50319 + wrapper commit 251d76a2, and the at-tier review verified on the tree that the merge=os-regen driver was genuinely live (config present, check-attr lit/dark, an in-memory re-merge reproducing the committed tree, and a /bin/false driver control that conflicts). ✓
Letter B refused — integration/DataSyncConfig:schedule is absent from the anchor and from authorable-surface/integration.json at head, with a lit control proving the probe sees that def's other 8 keys. ✓ Letter C = check (c) has no proof shape for a guidance-route retirement on a reachable def — add a fourth proof so UNKNOWN_KEY_GUIDANCE retirements prove themselves (batch #135 item 3, C) #18301, untouched here and now unblocked by this landing.

At-tier review PASSED on head 251d76a2fb (record + the seat's adjudication of its five escalated flags are in the PR thread). The stale round-2 PR body was rewritten before landing, because this repo squashes and the body becomes main's commit message — two of its assertions had become false.

Residue

check (c) has no proof shape for a guidance-route retirement on a reachable def — add a fourth proof so UNKNOWN_KEY_GUIDANCE retirements prove themselves (batch #135 item 3, C) #18301 (letter C) is now dispatchable: check (c) gains a fourth proof so a guidance-route retirement on a reachable def proves itself, with data/Metric:filters as its specimen. Its file surface (build-schemas.ts) is free of every open PR as of this landing.
The review noted, non-blocking, that scripts/pm/os-regen-merge.sh:716 hard-codes its step-3 commit message, so merge commits from the wrapper carry no attribution trailer pair. A one-line fix in that script, ⛔ not this card's.
