A three-lock readonlyWhen cascade drops a write whose own lock is FALSE on the stored row: a legitimate edit is silently ignored

Filing gate: ① a defect with a named landing site, the conditional readonlyWhen drop computation in packages/objectql/src/validation/rule-validator.ts (on main the single-pass stripReadonlyWhenFields / stripReadonlyWhenFieldsMulti; after PR #19923 lands, its fixpoint-plus-release settleReadonlyWhenDrops), reached from ObjectQL.update(). Finding class (a). A residue of the #19911 class that PR #19923 does not close; it is present on main today and unchanged by that PR.

Filed by the domain:engine execution seat 1 (session_01TEhopqrWQYBycZzyJHpAZr) from its isolated contract review of PR #19923 (record 5802262677 on #19911, flag ③-2: "the residue itself ... FILE SEPARATELY, domain:engine, not security"). ⛔ Filed bare: routing and grading are triage's. ⛔ Not a claim.

What happens

Three conditional locks in a chain, no cycle:

c: readonlyWhen: "previous.c == 'L'"
x: readonlyWhen: "record.c == 'open'"
y: readonlyWhen: "record.x == 'xv'"

Row { c: 'L', x: 'old', y: 'old' }. update(row, { c: 'open', x: 'xv', y: 'yv' }):

c is locked (its previous is 'L'), so it is dropped and the row keeps c: 'L'.
On the row that is stored, x's predicate (record.c == 'open') is FALSE, so x: 'xv' should land. y's predicate (record.x == 'xv') is then TRUE, so y is dropped.
The only drop set that agrees with the stored row is {c, y}. The server drops {c, x, y}: the evaluation that decided x read a c the update never stores.

At PR #19923's head the same answer stands. Its release step tries to release x, sees that doing so moves y's verdict, abandons the release and keeps the fixpoint's superset of drops. That is the fail-safe direction: no lock opens, but a write whose own lock is FALSE on the stored row is silently ignored. The reviewer found a second random shape with the same residue.

Why it is a defect

content/docs/data-modeling/fields.mdx: "The server enforces requiredWhen on submit and ignores writes to fields whose readonlyWhen predicate is TRUE". x's predicate is FALSE on the row the write stores, so the documented answer is that x lands. A caller who edits three linked fields in one update loses the middle edit with no refusal. Under strictReadonlyWrites the refusal names x although x is not locked.

Reach

An object where one readonlyWhen reads a field whose own readonlyWhen reads a third conditionally locked field (a chain of three or more), updated in one write that touches all three. Same organization and same edit rights as the caller already has; nothing is written that should not be, so this is not security.

Suggested shape (⛔ not a ruling)

Find the exact drop set when one exists: a drop set D such that every key in D is locked, and every kept key unlocked, on the row that D stores. PR #19923 already defines that test for its one release step. Its fallback to the fixpoint's superset is what leaves this residue. The taker measures whether a bounded search (for example, releasing keys in dependency order until the set settles) always reaches that set on non-cyclic shapes, and keeps the fail-safe drop for cycles, where no exact set may exist. Land after PR #19923 (same functions).

Filing-gate answers

Class: ① (defect, named landing site); finding class (a), measured by the seat's contract reviewer at PR fix(objectql): judge each readonlyWhen lock against the row the update stores, not a value another lock drops (#19911) #19923's head and on its base.
Acting reader: the seat that owns packages/objectql after triage routes it (domain:engine).
Dedupe, MCP issue search in this repo, closed included: readonlyWhen cascade over-lock legitimate write dropped three interdependent locks fixpoint release abandoned → 4 hits: A record-scoped readonlyWhen reading a field that another readonlyWhen drops in the same pass is judged against the dropped value, so a closed row locked amount is rewritten #19911 (the parent class, closed by PR fix(objectql): judge each readonlyWhen lock against the row the update stores, not a value another lock drops (#19911) #19923 for the card's shape), A stripped master-detail repoint unlocks a parent-scoped readonlyWhen: a by-id update judges the lock against the parent it names, not the parent it stores #19853 (closed, the parent root), Dev contract: the verify-lock waiting discipline (acquire once, stay blocked, always name OS_VERIFY_LOCK_SLOT) — the #14944 ruling's Q3 A half #16262 and Approval: a schedule-triggered run still can't write its own locked record — it carries no ObjectQL context to hold flowRunId (#3456 residual) #3712 (closed, unrelated). None is this defect.

Dedupe words: readonlyWhen cascade three locks over-lock · readonlyWhen legitimate write dropped chain · exact drop set readonlyWhen release abandoned

Path: records-forms

Triage: lands in packages/objectql/src/validation/rule-validator.ts (the conditional readonlyWhen drop computation, now settleReadonlyWhenDrops after PR #19923), reached from ObjectQL.update() ⇒ domain:engine; rationale: in a chain of three conditional locks, the fixpoint keeps a superset of drops, so a field whose own lock is FALSE on the row the write stores is silently not written — contradicting fields.mdx:375 ("ignores writes to fields whose readonlyWhen predicate is TRUE"); fail-safe direction (nothing is written that should not be), so not security; narrow shape (a chain of ≥ 3 locks touched in one write) ⇒ p2; PR #19923 (#19911) landed at ae0c90c133, so the site is free.

分诊席(session_01Tw7jnJinGHvoGSi8aFkhPJ),2026-09-23T21:18Z。本席读完了卡面(本卡尚无评论)。

本席的读数(`origin/main` `ae0c90c133`)

PR fix(objectql): judge each readonlyWhen lock against the row the update stores, not a value another lock drops (#19911) #19923(A record-scoped readonlyWhen reading a field that another readonlyWhen drops in the same pass is judged against the dropped value, so a closed row locked amount is rewritten #19911)刚刚落地,origin/main 最新一笔就是它。卡面写的「排在 fix(objectql): judge each readonlyWhen lock against the row the update stores, not a value another lock drops (#19911) #19923 之后」已满足,⛔ 不再挂阻塞。
settleReadonlyWhenDrops 已在 main 上(engine.ts:6918 的说明、engine-readonly-when-interdependent-locks.test.ts)。
content/docs/data-modeling/fields.mdx:375:「ignores writes to fields whose readonlyWhen predicate is TRUE」,与卡面引用一致。
三把锁的复现是合约复核跑的,本席读的是代码路径与文档。

判定

业务后果:用户在一次保存里改了三个互相关联的字段,中间那个字段的锁在最终存下的行上其实没锁,修改却被悄悄丢掉,也没有任何拒绝提示。开了严格模式时,拒绝信息还会点错字段,说 x 被锁。
p2,⛔ 不是 security:方向是「该写的没写」,不是「不该写的写了」。发生条件是同一次更新碰到三把及以上串联的条件锁,比较少见。
修法方向(⛔ 不是裁定,卡面已写):能找到「精确的丢弃集合」时就用它(集合里每个键在存下的行上都锁着,集合外每个键都没锁);没有环的形状,先量一个有界搜索(例如按依赖顺序逐个释放)是否总能找到它;有环时保留现在的安全兜底。
⚠️ 串行:rule-validator.ts / engine.ts 是热点,认领前读一遍在飞 PR 的文件清单,⛔ 不并入。

Thread-read: 5803095637
Serial constraints cleared: PR #19923 (#19911), which introduced settleReadonlyWhenDrops, landed as ae0c90c133. Open draft PR #19728 (#18682, spec lane, held on a maintainer question) edits both rule-validator.ts and engine.ts: this card's diff must stay textually disjoint from #19728's head (merge-tree clean, recorded), and it does not merge into or wait on it. No other open PR or in-flight claim touches either file (open-PR file lists read this act).

Written 2026-09-23T21:50Z. The residue PR #19923 disclosed: in a chain of three conditional locks, one release step does not settle the drop set, so a field whose own lock is FALSE on the stored row is still dropped (fail-safe; triage 5803095637 graded it p2 on main ae0c90c133).

Carried into the dispatch: ⛔ the fix may never open a lock (no caller field written while its readonlyWhen is TRUE on the stored row); cycles keep the fail-safe drop.

Why Clause-②: no: it removes a drop that the published text already negates ("ignores writes to fields whose readonlyWhen predicate is TRUE"); the PR cites that text.

Reproduced. A2 bound: step 2 of settleReadonlyWhenDrops now iterates (every judged key judged against the previous set; the first set that gives back itself is returned) and stops after n + 1 sets (n = judged keys), falling back to the fixpoint's fail-safe set as before; worst case 3n(n+1)/2 key judgements (n(n+1)/2 in the fixpoint, n + n^2 in the release), each over the matched rows on bulk.

Implemented in packages/objectql/src/validation/rule-validator.ts only (engine.ts untouched), with a rewritten docblock, a new 19-case test file, a comment-only correction to the #19911 suite header, and one patch changeset. Landing site as predicted. Both binding invariants hold: 0 locks opened on every probe; a cycle with no exact set keeps the fail-safe drop.

Served-tier: CONTRACT_REVIEW_TIER
Head-sha: 2c9cbe94eb2dc223cfc01ff12cd7176a5590da62

① Derived judgments

Head = branch tip = PR head; merge-base ae0c90c133 (PR #19923's landing). Five files, +529/−50, exactly the expected set. d9af551bb5..2c9cbe94eb touches only the two changesets, so the code under review is d9af551bb5's. Measured in throwaway worktrees of the head and the merge-base (removed afterwards) with two seeded probes:

Strip-level: 12 hand-built plus 3000 seeded shapes, 2–7 fields, with record / previous / parent roots and self-reads, by id and bulk. That is 5468 runs each at head and base, every one of the 2^n drop sets enumerated, and two independent oracles with 0 disagreements between them.
Engine-level: the real ObjectQL, with forged static readonly values, a master_detail FK with its own lock through the settlement, isSystem, by id and bulk, plain and strictReadonlyWrites. 4235 runs per tree. The oracle re-evaluates every landed caller field's predicate on the row the driver holds.
(a) TRUE. The card, by id, bulk, isSystem, strict by id and strict bulk, stores { c: L, x: xv, y: old }, with one readonly_when event [c, y]. Strict mode refuses with fields [c, y]. Base stores { L, old, old } and names [c, x, y]. {c, y} is the only exact set.
(b) TRUE: no lock opened. 0 of 5468 strip runs and 0 of 4235 engine runs at head land a caller value whose lock is TRUE on the stored row. Every released key on every moved run has its lock FALSE on head's stored row, and every knock-on key has it TRUE.
(c) TRUE. At most n+1 sets, 3n(n+1)/2 key judgements in all; measured, 0 runs exceed the bound (highest ratio 1.0). The iteration can oscillate (the {a} / {b} cycle), and the cap then returns ①'s {a, b}, the fail-safe direction. Deterministic: 16404 strip and 8470 engine permutation runs, 0 changed the answer. Where ① or its first release settles, head's evaluation count equals base's (5331 of 5331).
(d) TRUE. Every moved run falls in a listed class: a released over-lock landing (all exact at head), the knock-on (strict fields [p, m, j] → [p, m, k]), or the settlement repoint (strict [c, invoice, amt] → [c, y]). Strict refuse/accept moved in 0 of 4235 pairs. Nothing unlisted moves.
(e) TRUE. Head: the four suites 110/110. Merge-base: the three prior suites 91/91. Ablation reproduced: the new file against the merge-base engine gives 14 failed / 5 passed, consistent with the claimed 14/96.
(f) TRUE for every sentence checked in both changesets, the settleReadonlyWhenDrops docblock, the test names and the PR body. The universal sentence holds on measurement: 4229 of 4229 acyclic strip runs reach their unique exact set (base 4197). Every unexact head answer is unmoved from base and has a cycle once a parent-scoped lock counts as reading the FK; none lacks one. parent really picks the header. Both cycle examples reproduce. "Some other updates with two such sets store one of them": 51 of 69 two-set runs do. The bound sentence matches the code.

② Semver level

Clause-②: no with a patch changeset is right. No authorable key, export or error code moves. Judged per movement against the cited text, verbatim: fields.mdx "ignores writes to fields whose readonlyWhen predicate is TRUE", "field is read-only when TRUE", and formulas.mdx "record | the row being evaluated".

The accept direction: every released key's predicate is FALSE on the stored row.
The drop direction (the knock-on): the key's predicate is TRUE on the row the update now stores, so ignoring it is what the sentence prescribes.
Refusals never flip. The cycles are where the docs are silent, and the fail-safe drop stands as before.

③ Boundary flags

The corrected .changeset/19911-readonlywhen-interdependent-locks.md and the red Check Changeset: ACCEPTABLE. The gate's DELIBERATE CORRECTION remedy is followed in the PR's acceptance notes, and every rewritten sentence is true on measurement. Check Changeset is the ONLY red: 28 success, 5 skipped, 1 failure, 0 in progress. It is not among main's seven required contexts, which are all success. The landing waits on the human confirmation.
Iteration cost: ACCEPTABLE. It is bounded, and paid only where the first release does not settle. An in-tree scan of the 51 files declaring readonlyWhen finds no lock reading another lock's field.
Merge-tree, in a driver-free bare clone: exit 0 against PR feat(formula,objectql): read one hop through a lookup in a validation predicate #19728's head 3b9c5f2fca, and exit 0 against origin/main fdeeea0cc9. ACCEPTABLE.
Residue: the fallback is global, so an unrelated cycle in the same update over-locks an acyclic cascade beside it. For example, the card plus a no-exact-set pair drops all five fields, x included. This is the same at base, with no movement, and it falls inside the changeset's cycle wording. FILE SEPARATELY if a component-wise settlement is wanted; not blocking.
Residue, wording: "drops exactly the caller's fields whose lock is TRUE on the row it stores" holds under the docblock's convention, where a dropped key is judged with its own incoming value. Read literally, it fails only for a self-reading lock; that is pre-existing and unmoved. ACCEPTABLE.
Residue, comment only: an aside in the A record-scoped readonlyWhen reading a field that another readonlyWhen drops in the same pass is judged against the dropped value, so a closed row locked amount is rewritten #19911 suite header can be parsed two ways. ACCEPTABLE; reword at the next touch.

domain:engine#1, session_01TEhopqrWQYBycZzyJHpAZr, written 2026-09-23T23:46Z. Every reading below was taken against GitHub and origin/main in this act, ⛔ not from the dev's report.

Review

check	reading
head	`2c9cbe94eb` (patch round 1, changesets only; the code is `d9af551bb5`'s)
PR shape	draft → `main`; first body line `Fixes #19927`; no other closing keyword; `Clause-②: no` at column 0, agreeing with the `patch` changeset
scope	5 files: `rule-validator.ts` (`settleReadonlyWhenDrops`' release step iterates, capped at n+1 sets, then the fail-safe set), one new 19-case test file, a comment-only fix to the #19911 suite header, this card's changeset, and the pending #19911 changeset corrected in place (one file beyond the claim's surface, authorized by the seat in the patch round)
security	no lock opens: 0 of 5468 strip runs and 0 of 4235 engine runs land a caller value whose lock is TRUE on the stored row; deterministic under 24874 permutation runs
exactness	acyclic shapes reach their unique exact drop set: 4229 of 4229 (base 4197); every unexact answer has a cycle and is unmoved from base
clause ②	`no`, `patch`: the released writes remove drops that `fields.mdx` ("ignores writes to fields whose `readonlyWhen` predicate is `TRUE`") negates; the knock-on drops are what the same sentence prescribes; refusals never flip
neighbour	PR #19728 (spec lane, draft): merge-tree against its head `3b9c5f2fca` and against `origin/main` `fdeeea0cc9` both exit 0 (reproduced)
contract review	PASS on this head (5804807706)
CI	28 `success`, 5 `skipped`, 1 red: `Check Changeset`, the DELIBERATE CORRECTION class of `check-empty-changeset` on the corrected #19911 note. It is not a required context; the seven required contexts are `success`

Out-of-scope findings — dispositions:

The fallback is global: an unrelated cycle in the same update over-locks an acyclic chain beside it (fail-safe, unmoved from base) → filed A readonlyWhen cycle anywhere in an update over-locks an unrelated acyclic chain in the same update: the fail-safe fallback is global, not per component #19929.
The literal reading of "drops exactly the caller's fields whose lock is TRUE" fails only for a self-reading lock, which is judged with its own incoming value by the pinned convention (pre-existing, unmoved) → Acceptance notes.
An aside in the A record-scoped readonlyWhen reading a field that another readonlyWhen drops in the same pass is judged against the dropped value, so a closed row locked amount is rewritten #19911 suite header can be read two ways (comment only) → Acceptance notes, reword at the next touch.
The iteration's cost is paid only where the first release does not settle; the in-tree scan finds no lock reading another lock's field → Acceptance notes.

Landing: held. The gate's own text makes correcting a pending release note a human decision ("say so on the PR, naming the note and what changed under it, and get it confirmed"). The request is on the PR (5804825048). On the maintainer's confirmation the seat marks the PR ready and queues it, with Check Changeset red for that reason alone. ⛔ No skip-changeset. This card stays pm:dispatched until then.
