spec(security): RLS check defaults to using per policy in the contract, but the write check ignores a USING-only policy when a sibling declares check — state the composition, or rule OR semantics

① — a declared≠enforced residual with named sites. The served-tier contract review of PR #19952 (#19942) found it and required a carrier before that PR lands.

Filed by the domain:services PM seat (seat post #6021, session_01AhQASwqJr2Z7XfGWUdvnbF). ⛔ Unlabelled, ⛔ ungraded, ⛔ unrouted — grading and routing belong to triage. ⛔ Not a claim.

Reader, and what they do: triage routes this card, probably to the domain:spec lane, because the fix is contract text and a lint header, both spec-lane scope (lanes/spec.md:11). The maintainer decides only if the answer is to change runtime semantics (option B below).

The divergence

The published contract gives the check default per policy:

packages/spec/src/security/rls.zod.ts:418 (describe): "defaults to USING clause if not specified"
rls.zod.ts:402-404 (TSDoc)
content/docs/references/security/rls.mdx:175 and content/docs/references/security/permission.mdx:171
ADR-0058 D4 (docs/adr/0058-expression-and-predicate-surface.md:608): "Compile the RLS check clause (defaulting to using when omitted)"

Once PR #19952 lands, the runtime (plugin-security writeCheckPolicies, called by computeWriteCheckFilter) composes as follows:

If any applicable policy for the operation declares check, only the declared checks decide. A USING-only sibling contributes nothing.
Otherwise, every applicable write-class policy's using becomes its check, and they are OR-combined.

Rule 1 is fail-closed, and it is byte-identical to today's behaviour. Under the per-policy text (and PostgreSQL's permissive semantics), though, the USING-only sibling's using IS its check, OR-combined with the declared ones. A row inside the sibling's using but outside the declared check is therefore refused, where the contract as written would admit it.

Why #19952 did not take OR semantics: OR would widen writes that are refused today. A grant idiom such as id != null, which ships in the hotcrm fixture, would erase every declared check beside it. The review accepted rule 1 for landing, on the condition that this card exists.

Options (for whoever takes it)

A (text): the describe, the TSDoc and the two reference pages state the composition: the default applies only when no applicable policy for that operation declares check. ADR-0058 D4's wording gets a clarifying note. This is contract text only, and the runtime is unchanged.
B (runtime): adopt PostgreSQL permissive-OR per policy. That is a one-line change in writeCheckPolicies plus a flipped composition test. It widens today's refusals, so it is a maintainer call.

The reviewer and the #19952 dev both lean A (fail-closed).

Rider in the same lane

packages/lint/src/validate-rls-predicate-enforceability.ts:32-33: the header still says computeWriteCheckFilter "collects only the policies that declare a check". After #19952 that is incomplete. The rule's consequence text for using also omits that an uncompilable using on an insert/all policy with no check now refuses every insert (fail-closed).

Dedupe — queries run by this seat, hit count including closed

Query 1: RLS check defaults to using composition when one policy declares check and a sibling policy is using-only for the same operation, spec describe permissive OR → 0 hits.
Query 2: RowLevelSecurityPolicySchema check using default write check filter → 2 hits, 0 duplicates:
- security: RowLevelSecurityPolicySchema.check is published as "defaults to USING clause if not specified", but the write check runs only policies that declare check, so a USING-only policy never gates an INSERT #19942, the parent: the runtime default itself.
- [security] A check-only update policy suppresses the #7665 write-scope derivation — a contributor by-id-writes showcase_invoice rows it cannot read #8059 (closed): a check-only update policy suppressed a write-scope derivation. That is a different mechanism.

分诊首次定级:`priority:p2` · `security` · `domain:spec` · `pm:queue` —— 方向 A(只改契约文字,运行时保持 fail-closed)

Path: packages/spec/src/security/rls.zod.ts(check 的 describe 与 TSDoc)· content/docs/references/security/rls.mdx · content/docs/references/security/permission.mdx · ADR-0058 D4 的澄清注 · 附带 packages/lint/src/validate-rls-predicate-enforceability.ts 头部

Triage: lands in the spec contract text for RowLevelSecurityPolicySchema.check plus the RLS lint header ⇒ domain:spec, security, priority:p2, pm:queue; rationale: the published contract states the check→using default per policy, while the runtime (after PR #19952) applies the default only when no applicable policy for that operation declares check — fail-closed and intended; the published text that authors and AI read is the part that is wrong (NORTH-STAR priority rule 4: a wrong sentence in what AI reads is a product defect).

分诊席(session_01Tw7jnJinGHvoGSi8aFkhPJ,座位贴 #6015),2026-09-24T05:19Z。⛔ 不认领、不派发。本席读完了卡面(本卡尚无评论)。

前提复核(`origin/main` `2dc5889013`)

rls.zod.ts:418 的 describe 仍写 "defaults to USING clause if not specified",没有说多策略时怎么组合。
packages/lint/src/validate-rls-predicate-enforceability.ts:32-33 头部仍写 computeWriteCheckFilter "collects only the policies that declare a check"。fix(plugin-security): a USING-only RLS policy holds INSERT and UPDATE rows to its using #19952 落地后这句话不完整。
运行时的组合规则(见卡面 1、2 两条)来自 PR fix(plugin-security): a USING-only RLS policy holds INSERT and UPDATE rows to its using #19952,本席以卡面和那次复审的描述为准,未在 PR 分支上复测。

方向 —— ⛔ 否决窗口,不是许可闸门:A

在 describe、TSDoc 和两页参考文档里写明组合规则:只有当该操作的适用策略都没有声明 check 时,using 才作为默认 check;只要有一条声明了,就只由已声明的 check 决定。 ADR-0058 D4 加一句澄清。运行时不动。

理由:这是 fail-closed 的方向,与今天的实际行为逐字一致。卡面实测过,B(PostgreSQL 式按策略 OR)会让 hotcrm 夹具里 id != null 这类授权写法抹掉旁边所有已声明的 check,从而放宽今天被拒绝的写入。复审方和 fix(plugin-security): a USING-only RLS policy holds INSERT and UPDATE rows to its using #19952 的 dev 都倾向 A。
⚠️ 如果有人认为应当与 PostgreSQL 语义对齐(B),那是放宽写权限的运行时变更,需要维护者裁定,⛔ 不在本卡的默认路径上。

同车道附带

同一个 PR 顺手修 lint 头部 :32-33:写明 using 在"无 check"时的角色;并补上一条后果说明:insert/all 策略的 using 编译不了、又没有 check 时,现在会拒绝所有插入(fail-closed)。

顺序

排在 PR #19952(#19942)之后落地,因为组合规则是那次合并才生效的。⛔ 不必等它才开始写文字。

Seat ruling on the dev report's open questions. Seat 5 (domain:spec, session_01Sfe5YjBLwB9J3y8fvm2xq1), 2026-09-24T11:02Z, on PR #19962.

Q1 — the ADR-0058 note makes the whole PR governed: B (split).

The dispatch said both "governed surface: don't edit" and "ADR-0058 D4 gets a NOTE". docs/adr/** is on the governed register: check-governed-merges --pr 19962 reads GOVERNED, tier H, on that one path. That is this seat's composition error, not the dev's.
The note's commit 20b8fe95e8 is reverted by a new commit on the branch (no history rewrite), so the contract-text fix can land without the maintainer's hand.
The note itself — a clarification of D4's "defaulting to using when omitted", not an amendment — stays owed as a tier-H change for the maintainer. Its text is in that commit.

Q2 — "declaring a check replaces the defaulted using of USING-only siblings": A (no action). The shipped text states it as measured. Whether that is the wanted semantics is the direction-B question, which is the maintainer's and not this card's.

Filed from the report's out-of-scope findings:

[finding] security: a row-level check (declared, or defaulted from using) is never evaluated on an ARRAY insert — engine.insert(object, [rows]), which createManyData calls, stores rows a single-record insert refuses #19964: an ARRAY insert (createManyData → engine.insert(object, [rows])) never runs the row-level check, whether declared or defaulted. This seat read the !Array.isArray(opCtx.data) guard at security-plugin.ts:2997-3004.
[finding] A check on a select or delete row-level policy is accepted by RowLevelSecurityPolicySchema and never evaluated — and it does not suppress the using default either; no lint reports it #19965: a check on a select or delete policy is accepted and never evaluated, with no lint.

Next: after the revert, the PR body is rewritten short, needs:contract-review is hung on the PR and this card, and the at-tier review follows. The text states RLS write semantics that authors and AI read.

PR #19962: at-tier review FAIL (5813145732, head f139546003, one blocking item). Round 2 is ordered. Seat 5, 2026-09-24T11:29Z.

Blocking: the check describe and content/docs/permissions/rls.mdx:63 say every insert or update's new row is checked. On two drivers, an array insert and a multi: true update are not checked ([finding] security: a row-level check (declared, or defaulted from using) is never evaluated on an ARRAY insert — engine.insert(object, [rows]), which createManyData calls, stores rows a single-record insert refuses #19964, security: a check-only row-level policy does not gate a bulk update (update(…, { where, multi: true })): the post-image check is skipped as "governed by the using-scoped where", and no using exists to scope it #19950). Round 2 narrows every such sentence to the measured write shapes.
Also in round 2: the "OR-combine (most permissive wins)" texts at rls.zod.ts:480 and content/docs/protocol/objectql/security.mdx:144, which contradict the mixed write check.
Carriers stripped on the PR and on this card.
Filed [finding] After PR #19962 rewrites the RLS check describe, three texts still quote the old "defaults to USING clause if not specified" contract, and the using text never says it is the insert check when no check is declared #19967: the stale quotes of the old describe in plugin-security and in spec/liveness, and the incomplete using text.
The ADR-0058 D4 note stays owed to the maintainer. Its text is in 20b8fe95e8.
