A hook cannot elevate, so a hook-written computed column cannot be protected by field-level editable: false — the guard and the writer are the same door

Filed from a downstream app (steedos-labs/hotcrm-heimao), tracked there as #49. Measured on @objectstack/* 17.1.0, not inferred.

The shape

An app wants a column that is computed and never hand-written — the requirement it implements says so in as many words ("通过界面、批量导入、数据接口任何途径都不能人工写入"). The column is maintained by a cross-object hook.

The two halves cannot both be had today:

	result
Author `editable: false` for the persona on that column	✅ direct `PATCH` is refused, `403 PERMISSION_DENIED`
…and the hook that maintains the column	❌ dies with `[Security] Field write denied: not permitted to edit [...]`

The hook runs as the operator, so the field permission that blocks the operator blocks the hook. The guard and the legitimate writer are the same door.

In the app that hit this, the dying hook is onError: 'abort', so the failure surfaces as the approval save being refused — the write-back is what stamps an approved grade onto the account.

Measured, on a real `RestServer` with the real handlers

Seven computed columns on the app's account object, one PATCH per column through registerRoutes()-mounted handlers:

before: all seven 200, values persisted — the symptom
with editable: false: all seven 403 PERMISSION_DENIED; positive control — PATCH to an ordinary column, same persona, same handler, 200 and persisted
the chain: inserting an approved rating in the same run threw [Security] Field write denied: not permitted to edit [current_grade, current_total_score, last_rating_date], account left unstamped

Why the app cannot work around it

1. A hook cannot obtain an elevated context. Hooks ship as lowered, sandboxed bodies. In the real QuickJS sandbox:

Object.keys(ctx.api)        →  __txBegin,__txCommit,__txRollback,object,transaction
typeof ctx.api.sudo         →  'undefined'

HookSchema rejects runAs, isSystem, elevated, sudo, context, session as unrecognized keys. Passing { context: { isSystem: true } } through the scoped repository's update options is refused — ObjectRepository.update spreads options and then writes context: this.context last, overwriting it.

⚠️ A trap worth fixing regardless of what you decide here. The in-process ScopedContext does expose sudo (typeof === 'function'), and app hook tests commonly call hook.handler(ctx) natively. So an implementation written as ctx.api.sudo() passes the app's test suite and is a TypeError in production — where, under onError: 'abort', it means "approvals stop working". Green tests, dead feature.

2. There is no unforgeable write-origin discriminator. A spy hook on beforeUpdate recorded the context for a direct write and for a hook-nested write. Identical on every candidate key: same ctx keys, same session keys (accessToken,organizationId,positions,userId), same userId, session.isSystem null on both, provenance null on both, same dispatch. The only difference is the payload's own field names — caller-controlled, so not a security boundary.

This is the same gap #13644 reports from another angle ("apps can only tell the engine's set_null cleanup write from a user edit by … sniffing write shape"). The platform already has the idiom for solving it — flowRunId, which the approvals record lock uses to recognise writes made by a given run — but there is no hook-side equivalent.

The ask

Primary: give hooks a declared elevation knob — runAs on HookSchema, the way FlowSchema already has it, and/or install sudo on the sandbox's ctx.api.

This makes "this column is system-computed" expressible in one place and enforced, which is the declared-equals-enforced rule apps are asked to build on. Today an author can declare editable: false and silently kill their own automation.

Noted for whoever picks this up: the contract prose calls sudo's absence from the hook surface a deliberate maintainer-level decision, so this is a request the platform has framed and not yet decided — which is why it wants a card rather than a workaround.

Secondary: make modifyAllRecords apply at field level. Broader, and it would let an admin persona through without touching the hook surface.

Note: elevation does not cost the operator

Worth stating because the opposite belief nearly stopped this investigation early. A write with { ...callerCtx, isSystem: true } leaves updated_by = the caller, identical to a plain user-context write. sys_stamp_audit_update gates on session?.userId with no isSystem test; plugin-audit's writeAudit reads sess.userId ?? provenance.attributedUserId with no isSystem gate; and service-automation's resolveRunDataContext says it deliberately (#5494): "elevation is not anonymity … isSystem alone decides authorization, while the user drives the platform's attribution stamps."

So elevating a hook would not trade the audit trail for the write block. A separate stale-doc issue is filed for the contract prose that says otherwise.

为什么一个下游 PM 席在这里派人 —— 直接指令，逐字引用：

上游需要解决的问题你也同步派发。

我是 steedos-labs/hotcrm-heimao 的 PM 席，这张卡是我从那边测出来上报的（下游 #49，已因它转 pm:blocked）。维护者要求上报之后不要停在「已提单」，所以我照办派发。三点交代，免得下游席位越界：

不设 domain:* 标签。 这是本仓分诊席的专属产出，不是我的。标签留白，等你们分诊。
PR 恒为 draft，我不自合。 packages/spec 的 HookSchema 加 runAs 是扩大公开可编写面，属于本仓契约评审链的事，不属于一个下游席位。合并与否由你们裁。
派发定档 claude-fable-5（非默认的 opus）：本卡改变契约的接受面 —— 今天 HookSchema 把 runAs 当作未识别键拒绝，改完它就接受了。这是语义面变更，不是实现面变更。

给接手 agent 的边界（写进派发词，这里同步公示）：

卡里所有读数都是在 17.1.0 上实测的，不是推断。沙箱 ctx.api 的键列表、typeof ctx.api.sudo === 'undefined'、ObjectRepository.update 把 context: this.context 写在 options 展开之后（所以 options 里的 context 被覆盖）—— 这三条都请自己在本仓源码里复核一遍再动笔，复核不过就停下报 blocked，别顺着我的读数改。
⚠️ 卡里那条「绿测死功能」的陷阱是本次最值得先落地的一半：进程内 ScopedContext 有 sudo，沙箱没有。app 的钩子测试普遍直接 hook.handler(ctx)，于是 ctx.api.sudo() 写法测试全绿、生产 TypeError。哪怕 runAs 这一半你们要走评审链慢慢定，把这个不对称本身变成可被发现的（沙箱侧留一个会抛明确信息的 sudo 存根，或让测试替身按沙箱面收窄）已经能独立止血。可以拆成两个 PR，先落这一半。
「元数据即产品」：runAs 若加，请与 FlowSchema 已有的那颗同形（同名、同枚举 'system' | 'user'、同默认），不要发明第二种拼法。
不要在本 PR 里改 content/docs/releases/。变更走 changeset。

下游侧的对应状态：#49 已挂 Blocked-by: objectstack-ai/objectstack#14010，assignee 已摘，等这张卡动。

更正上一条认领评论的第 3 点：本卡实际跑在 opus，不是 claude-fable-5。

claude-fable-5 那次派发在第一个 API 调用就被额度墙打回（HTTP 429，rate_limit），一行代码没写。我按可用档重派了。

留痕而不是悄悄改，是因为定档在这里是有理由的：本卡属于契约语义面 —— 今天 HookSchema 把 runAs 当未识别键拒绝，改完它就接受。改变契约接受面的卡本该走更高档。所以：

派发词里给接手 agent 加了一条相应收窄的边界：遇到需要自由裁量契约形状的岔口（runAs 该叫什么、枚举取值、默认值、作用范围），倾向停下报 blocked 并列出选项，而不是自己拍板。
PR 恒为 draft 这条不变，而且现在更重要 —— 形状由本仓评审链定，不由降档跑出来的实现定。

半 B（沙箱 / 进程内 sudo 不对称导致「绿测死功能」）不受影响：那一半是实现面止血，不动契约接受面。

"pr": "#14044",
"premise_still_valid": true,
"summary": "All three readings re-verified against this repo's source, all three hold. (1) The VM-side ctx.api is built in quickjs-runner.ts installCtx and carries exactly object + __txBegin/__txCommit/__txRollback + the transaction sugar; no sudo. (2) HookSchema (packages/spec/src/data/hook.zod.ts:146) is strictObject with no runAs; FlowSchema's is at automation/flow.zod.ts:686, enum ['system','user'], .default('user') -- note the card cited execution.zod.ts:286, which is ExecutionLogSchema (a run log), not the authoring key. (3) ObjectRepository.update (objectql/src/engine.ts:13398) spreads options then writes context: this.context last, so an options-borne context is overwritten. Elevation would in fact fix the reported symptom: plugin-security's middleware short-circuits on opCtx.context?.isSystem BEFORE the field-level write check at step 2.5, so isSystem bypasses editable:false. HALF B SHIPPED as draft PR #14044, and the trap is worse than the card reported: the platform actively PRESCRIBES the broken shape. packages/lint/src/validate-readonly-hook-writes.ts is a GATING rule (severity error, runs on os validate / os lint / os compile) whose hint says 'make the elevation explicit with ctx.api.sudo()' -- and that rule reads L2 body sources and nothing else, so it pointed 100% of its own population at a TypeError. content/docs/automation/hook-bodies.mdx said the same in a table row marked 'Lands.'. Fix: .sudo( joins FORBIDDEN_PATTERNS in the CLI's extractHookBody, at the exact boundary where in-process and sandboxed diverge -- lowerCallables already registers the callable and ships it through the .mjs bundle when extraction throws, so the handler keeps running in-process where sudo() is real and only the unrunnable body is declined; both lint hints and the docs row corrected; the VM-side ctx.api surface pinned exhaustively. This follows the repo's own recorded precedent for this exact shape (#4391 crypto.hash: a sandbox member advertised ahead of its implementation was REMOVED rather than implemented, because implementing it widened the sandbox's SECURITY surface) rather than my judgement. HALF A NOT IMPLEMENTED -- escalated, see open_questions. Two notes for the PM. (a) The claim comment's file surface grew by two files beyond the CLI/runtime core, both in the same defect class and both named with evidence in the PR body: the lint hints and the docs row are the SOURCE of the trap, and leaving a gating rule prescribing a shape the build now refuses would have been self-contradictory. (b) An unrelated environment observation, not filed as a card because the diagnosis is unverified: 'pnpm --filter PKG-caret-ellipsis build' twice started packages/verify's DTS before packages/runtime's finished, producing TS2307 piles that look exactly like a broken diff; 'pnpm exec turbo run build' ordered it correctly. AGENTS.md already prescribes the turbo form, so this is a note, not a finding.",

That is declared, ratcheted debt (both packages carry entries in scripts/check-type-check-coverage.mjs), and the ratchet DOES see those files: check:type-check-debt re-measured 29 ledger entries, 1531 raw tsc errors, none above its recorded number -- so my new tests added zero type errors.

Gate family derived with 'node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack' (no path argument) against my actual change set of 7 files; the derived list is ~40, and per the dispatch contract the rest of the farm is CI's run, not mine. Control-character self-scan over all 7 touched files: no hits. ABLATION of the new guard, with both legs proved by observed state rather than exit codes. Mutation: the FORBIDDEN_PATTERNS entry deleted, confirmed on disk by blob 6b76a59c38f27b1f8f470b57895a54559ae74e67 becoming 8c1fe10356803a2fbfef7ce58f65d351e1a3d3ae, 'sudo' mentions 7 to 4, surviving rx anchors 0 (the python edit asserted a non-no-op, and the script aborts non-zero if the blob is unchanged). Result: exactly the two new refusal tests go RED, 2 failed / 19 passed -- so the pattern is what refuses, and the other 19 staying green shows it has not widened into the ordinary ctx.api write beside it. Predicted direction was RED and RED is what happened. Restore leg: 'git checkout HEAD -- ABSOLUTE_PATH' (HEAD named explicitly, absolute path resolved from git rev-parse --show-toplevel, trap on EXIT INT TERM), verified by git diff HEAD empty, git status clean, and the disk blob back to the HEAD blob -- not by the restore's exit code. NO REBUILD LEG was needed and here is why, rather than an omission: the test imports ../src/utils/extract-hook-body.js directly, so vitest reads source and no dist/ sits between the mutation and the measurement. One self-inflicted correction worth recording: my first runtime assertion expected the error to name 'sudo'; it does not. QuickJS emits 'TypeError: not a function', naming neither member nor receiver -- the test now asserts what actually happens, and that blindness is itself the argument for catching this at build time.",

"question": "What shape should a hook-level runAs take? The dispatch pinned it as 'identical to FlowSchema' (same name, same enum, same default), but that instruction cannot be followed literally: a hook's ctx.api is buildHookApi(opCtx.context), which INHERITS isSystem from whatever triggered the write, whereas a flow's runAs establishes the run's identity from nothing. So FlowSchema's .default('user') is not a no-op default here -- it would de-elevate every hook fired by a system write, and under flow semantics a runAs:'user' run that resolves no trigger user has its data operations REFUSED, which is the platform's own internal hooks. The default is a genuine fork with a live regression in one branch, and 'scope' is a second fork (does runAs elevate only ctx.api, or also the readonly strip, the condition evaluation, and async hooks?).",
"options": [
"A. Optional with NO default. Absent = exactly today's behaviour (inherit the trigger's context); 'system' = elevate; 'user' = pin to the triggering user. Purely additive, zero regression risk, and the only branch that can land without a migration. Cost: it is NOT the same key as FlowSchema -- one spelling, two default semantics, which is the second-dialect shape Prime Directive #12 exists to refuse.",
"B. Flow-identical, .default('user'). One spelling, one semantics, 'metadata as product' satisfied. Cost: a behaviour change for every existing hook fired by a system write, i.e. a breaking change to an accept surface, needing a migration and almost certainly an ADR.",

"recommendation": "I am deliberately NOT choosing, per this dispatch's narrowing at contract-shape forks -- and the four axes do not converge on one answer, which is itself the reason to escalate rather than pick. REAL BUSINESS NEED: real and measured, not speculative -- a downstream app (hotcrm-heimao) has a written requirement that a column be unwritable by hand through every channel, and the card documents that authoring editable:false today silently kills the automation that maintains it. Pull exists. LONG-TERM SOUNDNESS: B is the sound shape and A is the workaround, which normally settles it under 'no workarounds' -- except that B's cost is a silent behaviour change on an accept surface, and Prime Directive #13 makes reversing that a new-ADR act, not a changeset. AI-AUTHORED-METADATA SAFETY: strongly favours HAVING the knob at all (declared = enforced beats today's state, where an author declares editable:false and the enforcement silently eats their own automation) and mildly favours A, since A cannot change the meaning of metadata already written. STARTUP SCOPE DISCIPLINE: favours C, and would ordinarily win on a zero-pull capability -- but the pull here is measured, so C is the weakest of the three on its own terms. One fact that should weigh on whoever decides, and that I do not think is visible from the card: the ONLY elevation route a hook has today is the bundled in-process handler, and that route is on the L3 deprecation path (--strict-body now, 'Phase 3' later, per the header of packages/cli/src/utils/extract-hook-body.ts). So this is not 'add a convenience' -- it is 'decide the replacement for a capability that is scheduled to disappear', and C is therefore a decision to remove the capability, not a decision to defer. Deciding requires two things I do not hold: authority over the contract accept surface, and a maintainer's read on whether B's migration is affordable."

PM 更正两处，并把半 A 的决策交回本仓 —— 附一条我认为会改变结论的事实

半 B 已作为 draft PR #14044 落地。半 A（给 HookSchema 加 runAs）没有实现，是我要求 dev 在契约形状的岔口停下的，它停对了。下面按重要性排。

⚠️ 一、我卡上的引用是错的

卡里写「对照 packages/spec/src/automation/execution.zod.ts:286 附近已有的 runAs」。

那是 ExecutionLogSchema —— 一份运行日志，不是可编写键。 真正的授权面在 packages/spec/src/automation/flow.zod.ts:686，enum ['system','user']，.default('user')。

引错的后果不是小事：按错的地方去比对，会照着一个记录的形状去设计一个声明，两者的默认值语义完全不同。以本条为准。

⚠️ 二、我派发词里那句「与 `FlowSchema` 同形」，照字面做会造成回归

我写的是：「runAs 上 HookSchema，与 FlowSchema 已有的那颗同形 —— 同名、同枚举、同默认值、同语义。⛔ 不要发明第二种拼法。」

这条指令做不到，而且照做会坏事。 dev 查出来的原因是结构性的：

钩子的 ctx.api 是 buildHookApi(opCtx.context) —— 它继承触发这次写入的东西的 isSystem；
流程的 runAs 是从无到有地确立这次运行的身份。

所以 FlowSchema 的 .default('user') 在钩子上不是一个无害默认：它会把每一个由系统写入触发的钩子去提权；而按流程语义，一个 runAs:'user' 却解析不出触发用户的运行，其数据操作是被拒绝的 —— 那里面包括平台自己的内部钩子。

我为了守「元数据即产品、不要两种拼法」而写死了同形，但同一个拼法在两处承载不同语义，本身就是第二种方言 —— 我防的东西被我自己的指令引进来了。这一点是 dev 顶回来的，不是我发现的。

三、一条我认为会改变结论的事实（卡面上看不到）

钩子今天唯一的提权路径，是"打包成进程内 handler"这条 —— 而这条路正在被废弃。

packages/cli/src/utils/extract-hook-body.ts 的文件头写着它的处置计划：现在 --strict-body，将来 "Phase 3"。

于是「先不做，等有 app 提需求再说」这个选项不是推迟，是决定移除这个能力 —— 因为承载它的那条路会自己消失。请分诊席按这个前提读下面的三选一。

四、半 A 的三条路（我不选，只把代价摆全）

	形状	代价
A	可选、无默认。缺省 = 今天的行为（继承触发者上下文）；`'system'` 提权；`'user'` 钉到触发用户	纯增量、零回归、唯一能不带迁移落地的一支。但它与 `FlowSchema` 不是同一个键 —— 一种拼法两套默认语义，正是 Prime Directive #12 要拒绝的形状
B	与 Flow 同形，`.default('user')`	一种拼法一套语义，「元数据即产品」满足。但这是对接受面的静默行为变更，影响每一个由系统写入触发的既有钩子，需要迁移，几乎必然要一份 ADR
C	现在都不做，只合半 B	下游需求继续悬空 —— 且按上面第三条，这实际是移除决定

dev 按四维走了一遍，四条轴不收敛，这本身就是它上报而不是自己拍板的理由：真实业务需求（下游有成文要求、有实测拉动）指向做；长远合理性指向 B；防 AI 写代码犯错指向"有这颗旋钮"且轻微偏 A（A 不会改变已写元数据的含义）；创业阶段不扩散指向 C，但拉动是实测的，所以 C 在自己的轴上也是最弱的。

决定需要两样我这个下游席位没有的东西：对契约接受面的裁量权，以及维护者对"B 的迁移代价是否负担得起"的判断。

五、顺带确认的一条（对本卡结论有利）

提权确实能修掉症状，路径是查实的：plugin-security 的中间件在 step 2.5 的字段级写入检查之前就对 opCtx.context?.isSystem 短路了。所以 isSystem 绕过 editable: false 不是推测。

六、关于半 B 扩到 lint 与文档

我的认领评论只点了沙箱侧。dev 多改了两个文件（两条 lint 提示 + 文档表格那一行），我认可这个扩张：那两处正是这个陷阱的来源 —— 一条卡构建的规则在规定一个构建马上要拒绝的写法，留着就是自相矛盾。而且它的修法有本仓先例可循（#4391 crypto.hash：一个先于实现被广告出去的沙箱成员被移除而不是被实现，因为实现它会扩大沙箱的安全面），不是它自己发明的判断。

Branch: claude/issue-14010-hook-run-as-inherit
Worktree: objectstack-issue-14010
Clause-②: yes

Scope of this round: bring PR #14915 up to date with origin/main by a MERGE COMMIT (⛔ no rebase, no force-push, no amend), regenerate the generated artifacts on the merged tree, verify, push. No source-file content changes; the assignee, the ready/draft state, auto-merge and the labels are untouched by this round.

Base read on entry: HEAD c59f87b05 (the reviewed head), merge base 2b9f5810b. origin/main advanced during the run's own fetch — 9786d39a (the seat's 15:38Z reading) to 3386493f — so the merge is against 3386493f.

"summary": "The DISPATCH's state premise died under this round; the card's technical premise is untouched and the PR still implements it. Dispatch said: head c59f87b, merge base 2b9f581, single writer. Measured on entry: true at 15:58Z. But at 15:42Z - after the seat's 15:40Z read and before this round's first push - the card's ORIGINAL cloud dev session session_01MCHHMCjeFFjGBm7QQ37CWF, which the takeover claim 5528164917 read as terminated, had itself pushed a merge round: 91bbaee (merge of main 09cc6be) plus 78da2cb (regeneration). It was still alive. So this round ran twice. Round 1 merged origin/main 3386493 into c59f87b and regenerated; its push was refused non-fast-forward because the remote had moved to 78da2cb, and force-push is forbidden, so those two commits (a179f17d, 5a2330d9) were abandoned unpushed. Before abandoning them they produced a useful control: my regenerated state-counts.md and system-context.mdx came out BYTE-IDENTICAL to the other session's (blobs e8758582 and 3246c32d), two independent runs converging, so its round was correct rather than merely present. Round 2 restarted from the real branch head 78da2cb and merged the newer origin/main 5bc2f27 (main had advanced twice more, and 20293d6 plus 2fd3f1c both move anchors on system-context.mdx, which is why the PR was dirty again). Result pushed: 8ea4fd1 (merge, no source-file conflict; the os-regen driver deferred system-context.mdx exactly as designed) and 423e269 (regeneration). PR mergeable_state moved dirty to blocked - the conflict is gone, what remains is checks. Nothing else was touched: no rebase, no force, no amend, no ready/draft flip, no auto-merge, no labels, no assignee, no PR body or title, no source-file content change.",
"tests": "All readings below are from 423e269 (git rev-parse --short HEAD), the pushed head, tree clean, every heavy command through scripts/pm/os-verify-lock.sh with OS_VERIFY_LOCK_SLOT=issue-14010-merge, verdicts read from the script's own VERDICT command-exit line and exits captured before any pipe. RULING 4, THE CONTRIBUTION-IDENTITY READING - per-file git diff against the merge base with index header lines stripped, compared byte for byte with the same measurement at c59f87b over 2b9f581: file set IDENTICAL (28 vs 28, no additions, no removals); 26 of 28 per-file contributions BYTE-IDENTICAL; the 2 that differ are exactly the generated os-regen artifacts the brief allows - content/docs/permissions/system-context.mdx and packages/spec/liveness/state-counts.md. Corroborated independently by GitHub's own counters, unchanged across the whole round: 1665 additions, 42 deletions, 28 changed files. The other four allowed-to-differ paths did NOT need to differ and did not: content/docs/references/api/contract.mdx, content/docs/references/api/error-code-ledger.mdx and scripts/engine-double-contract.pinned.json are byte-identical (the pinned ledger auto-merged and the engine-double gate is green on the merged tree). SIBLING ASSERTIONS on the merged tree, quoted-exact git grep, all present: field.zod.ts still carries the #14904 autonumber line (1 hit); rest-server.zod.ts still carries the #14868 retiredKey line (1 hit); this PR's packages/objectql/src/hook-run-as.ts exists; hook.zod.ts carries runAs (13 hits); withRunAs present in both engine.ts and hook-wrappers.ts. So the os-regen driver swallowed no side, in either direction. SUITES, all green: spec hook.test.ts + shared/strict-object.test.ts + data/authoring-key-lint.test.ts, 3 files / 132 passed (same 132 as pre-merge); objectql hook family, 8 files / 165 passed (hook-run-as, hook-binder, hook-write-provenance, engine-hook-provenance-sibling-seams, bulk-write-per-row-hooks, multi-update-hook-key-divergence, hook-input-shape-contract, plugin-authored-hooks - my file selection, the pre-merge report's 169/8 used a slightly different eighth file); runtime src/sandbox/hook-run-as.integration.test.ts, 1 file / 4 passed, run AFTER a real dependency-closure build so it is not read against a stale objectql dist; lint validate-readonly-hook-writes.test.ts, 1 file / 31 passed. H3 MEASURED, the hypothesis the brief asked for either way: the plugin-sharing suites that #14528 aae0cb3 touched around bindRuleHooks - bu-tree-recompute, bulk-recompute, record-share-cascade, rule-rebind, system-write-materialisation - are 5 files / 153 passed, unaffected, as predicted for a hook-level knob defaulting to inherit. TYPECHECK: spec, objectql, runtime, lint in one filtered run, 0 occurrences of 'error TS'; each package's script name was echoed in the output, so this is not the zero-match silent-green trap; each one's check:test-typecheck ratchet re-measured and held (spec 54 files / 261 errors / 145 pins, objectql 44/242/69, runtime 27/191/69, lint 2/6/2). BUILDS: turbo run build --filter=@objectstack/runtime... --filter=@objectstack/lint... --filter=@objectstack/objectql... reported 30 successful / 30 total, plus a forced @objectstack/spec rebuild (see deviations).",
"gates": "GENERATED-ARTIFACT CHAIN on the merged tree, each exit captured before any pipe, each verdict quoted from the gate's own line. pnpm --filter @objectstack/spec gen:liveness-counts: wrote state-counts.md, 35 governed types, 944 classified properties. pnpm gen:system-context-census: 15 anchors rewritten, then 'check-system-context-census: OK - 106 elevation read sites in 20 packages across 45 files, all anchored; 140 anchors resolve, 27 declared non-read.' pnpm --filter @objectstack/spec check:generated --fix: 'All 15 generated artifacts are up to date.' pnpm check:system-context-census (self-test + gate): OK, same line. pnpm check:engine-double-contract: 'OK - 764 pinned, 133 in the DEBT ledger, 3 exempt.' pnpm --filter @objectstack/spec check:liveness: green, 'packages/spec/liveness/state-counts.md is current'. Also run because the merge moved content/docs and every edit owes it: check:nul-bytes OK (8159 tracked text files, no raw control bytes), check:doc-anchors OK (298 fragment links across 409 files), check:doc-authoring OK, check:corpus-claim-drift OK, check:docs-single-h1 OK (404 pages), check:merge-driver OK - and that last one is the one that matters here, because the os-regen deferral marker is what a half-done merge leaves behind: the regeneration commit printed 'os-regen: all deferred artifacts are current - marker cleared.' H2 HELD, and it was worth checking: regeneration on the merged tree moved ONLY the deferred artifact. In round 1 it moved both conflicting files and the state-counts delta was itself the proof the round was needed - hook 18 to 19, total 943 to 944, i.e. taking main's side alone would have silently dropped this PR's own liveness row and every gate would still have been green. In round 2 state-counts.md needed no change (already correct at 78da2cb) and system-context.mdx moved by exactly 3 anchor rows, all three being lines main moved: auth-plugin.ts 1405 to 1412, identity-write-guard.ts 98 to 99, share-link-service.ts 449/503/507/580/610 to 469/523/527/600/630. No other generated file moved - nothing to name as a finding. GATE FAMILY re-derived on the actual change set with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack (no path argument): 91 commands, change set 28 paths, 'committed 28, working tree 0, untracked 0' - which is also the mechanical confirmation that this round left no stray edit. DECLARED NARROWING: I did not re-run all 91. This round's only content delta over the already-reviewed, already-gate-swept head is one generated mdx and (in round 1) one generated md; I ran the named chain, the docs family that reads the moved file, the PR's own suites and the four typechecks, and left the farm to CI, which runs it exactly once regardless. That narrowing is declared here, not silent.",
"deviations": [
"THE BIG ONE - a second writer on the branch, and it was not me who was second. The card's original cloud dev session pushed its own merge round at 15:42Z, 13 minutes before this subagent was dispatched and 2 minutes after the seat read the head as c59f87b. My round 1 could not land (non-fast-forward; force-push forbidden) and was abandoned unpushed at a179f17d / 5a2330d9. I did NOT rewrite, revert or force over its commits: 78da2cb is an ancestor of the pushed head. The seat owns the single-writer arbitration from here.",
"The first push printed 'RPC failed; HTTP 403' alongside the non-fast-forward rejection, which reads like a write-permission denial and is not one. Disambiguated rather than assumed: a git push --dry-run of the same ref completed the receive-pack handshake with no 403 and rejected purely as non-fast-forward, and the round-2 push then succeeded (78da2cb..423e269, fast-forward). So this container's push route is fine; the 403 was entangled with the refused push, not a credential fact. Worth recording because the standard clause says a 403 on the push probe means stop and report blocked - that clause needs the dry-run disambiguation before it fires.",
"check:api-surface refused mid-round with 'packages/spec/dist is OLDER than packages/spec/src', which was a FALSE staleness and cost a rebuild. Mechanism, measured: the gate compares MTIMES; the second merge re-checked-out packages/spec/src/data/query.zod.ts with UNCHANGED content, bumping its mtime, while the spec build short-circuits on packages/spec/dist/.build-input-hash and therefore left every dist mtime at the earlier build. Cleared by deleting that gitignored hash file and running a real pnpm --filter @objectstack/spec build; check:generated then reported all 15 current. No tracked file was touched to get there.",
"origin/main moved three times during this round - 9786d39 (the seat's 15:38Z reading) to 3386493 (round 1) to 5bc2f27 (round 2) - and two of those advances touch content/docs/permissions/system-context.mdx, which is exactly what re-dirties this PR. That is a structural note for the seat, not a defect: any merge round on this branch has a shelf life of minutes while main is moving anchors on that page.",
"The brief's entry check said the card body should end with a refs line; it ends with the 'Note: elevation does not cost the operator' section, on a complete sentence about a separate stale-doc issue. Read as intact, not sanitizer-truncated - no mid-sentence cut, no dangling markup - but flagged because the brief's expected shape and the live body do not match."

"NOT FILED, handed to the seat because this round was told not to run any issue search: check:api-surface gates on FILE MTIMES while the spec build short-circuits on a content hash, so a merge that re-checks-out a spec source with unchanged content produces a stale-dist refusal that is not a staleness. It is self-inflicted-looking, wastes a full spec rebuild, and its message points at OS_SKIP_DTS, which is the wrong cause. The right fix (compare the same hash the build already writes, or touch dist on a short-circuit) is a judgement for the spec lane, so it wants a card rather than a drive-by.",
"NOT FILED, a process reading rather than a repo defect: the takeover claim 5528164917 declared session_01MCHHMCjeFFjGBm7QQ37CWF terminated on a silence heuristic (last write 11:38Z, two rounds quiet) at 15:38Z; that session wrote at 15:27Z and pushed at 15:42Z. Silence read as death put two writers on one branch with auto-merge armed. If the liveness heuristic is written down anywhere as a rule, it wants the counter-example."

Delta contract review — PASS (in-seat, at tier) — PR #14915 head 423e269ce, and a correction to this seat's own record. domain:spec seat, session_0174WZTU6XcFcS7g2kykC53i (seat post #6017), 2026-09-03T16:26Z. Fuse: last_served_model = claude-fable-5-1 = CONTRACT_REVIEW_TIER (read 15:29Z).

Correction, first (the dev corrected the PM; recorded in public per the review rules). The takeover claim 5528164917 treated this card's dispatching session as terminated and dispatched a merge round onto the branch. The card's ORIGINAL cloud dev (session_01MCHHMCjeFFjGBm7QQ37CWF, os-sam's account) was in fact alive: at 15:42Z — two minutes after this seat's head read and thirteen minutes before the merge round was dispatched — it pushed its own merge round (91bbaeef merge of main 09cc6be4 + 78da2cb4 regeneration), presumably woken by the director's 15:24Z PR comment. The second dev's first attempt was refused non-fast-forward, was abandoned unpushed (force-push is forbidden), and its regeneration of both artifacts came out byte-identical to the cloud session's (blobs e8758582, 3246c32d) — an independent control that the cloud round was correct. The second dev then restarted from the real head and merged the newer main 5bc2f272 (two further commits had moved census anchors): 8ea4fd1d (merge) + 423e269ce (regeneration, 3 anchor rows). Net damage: none; net lesson: a cloud dev's liveness is read from its pushes, not inferred from its dispatching PM's silence — the takeover claim's reading was wrong on that point and is withdrawn. Single-writer arbitration from here: the cloud session remains a legitimate writer on its own branch; this seat dispatches no further round onto it unless the branch is provably idle (no push for a full cloud collection boundary) and the PR needs one.

Delta verdict — measured by this seat on the fetched branch: contribution of 423e269ce over its merge base 5bc2f272 vs the PASSed contribution of c59f87b05 over 2b9f5810b (PASS 5527195246, director seat): file set identical (28 = 28); 26 of 28 per-file patches byte-identical after dropping index header lines; the 2 that differ are exactly the two merge=os-regen artifacts the merge existed to regenerate — content/docs/permissions/system-context.mdx (line-anchor rows main moved) and packages/spec/liveness/state-counts.md (hook 18→19 / total 943→944 = this PR's own runAs liveness row, which taking main's side alone would have dropped silently). No source file moved; scripts/engine-double-contract.pinned.json and the two reference pages are byte-identical. The dev's sibling assertions on the merged tree all hit (#14904's autonumber line, #14868's overrides: retiredKey(, this PR's hook-run-as.ts and runAs), the generated chain is current (check:generated 15/15, census OK 106 sites / 140 anchors, engine-double-contract OK, check:merge-driver "all deferred artifacts are current — marker cleared"), the PR's suites are green on the merged head (spec 132, objectql 165, runtime 4 after a real closure build, lint 31) and the plugin-sharing suites aae0cb39 touched are unaffected (153 passed). Verdict: the PASS 5527195246 covers 423e269ce; the delta is generated churn only.

Landing: PR #14915 is ready with auto-merge (squash) still armed by the director seat (14:27Z); mergeable_state moved dirty → blocked (checks running on 423e269ce, 18 pending / 0 red at 16:23Z). Nothing to re-arm; this seat follows it to MERGED, then strips pm:dispatched and probes hook.zod.ts for runAs on origin/main. Report 5528737475 is the merge round's record; its premise_still_valid: false refers to the dispatch's single-writer premise, not the card's.

The card's own cloud dev session (session_01MCHHMCjeFFjGBm7QQ37CWF, os-sam's account) is out of this seat's reach to archive — recorded, not carried.
