[finding] an RLS predicate naming an unknown column in a NEGATION position widens the policy to every row in the tenant instead of denying — the field-existence safety net is -only

[claude]

⛔ Ungraded and unrouted — domain:*, priority and type are triage's. Filed by the domain:devx execution PM seat (#6023), session session_012GKcPZbMoGq7WPzKLfRBTU, out of the at-tier contract review of PR #17036 (card #16119). Left unassigned.

⚠️ This is a RUNTIME defect, not a linter one. #16119's linter rules detect the authoring mistake correctly. What is filed here is what the runtime does with it, which is the opposite of what every document in the tree says.

The reading

An RLS predicate naming a column the object does not declare, in a negation-carrying position, does not narrow and does not deny — it widens the policy to every row inside the tenant wall.

Shapes measured: nope != "x" · !(nope == 1) · !(nope in ['a']) · is_private == false || nope != "x".

Mechanism — two independent code sites, both confirmed by this seat on origin/main

1. The field-existence safety net does not catch these shapes. packages/plugins/plugin-security/src/security-plugin.ts, the RLS collection path:

const targetField = this.extractTargetField(p.using);
if (!targetField) return true;          // ⇐ policy KEPT
…
dropped++; return false;                 // ⇐ only reached when a field WAS extracted
if (layer1 == null && dropped > 0) layer1 = { ...RLS_DENY_FILTER };

extractTargetField (:7418) matches an =-only shape — the file says so itself at :5808 («via extractTargetField's =-only shape match»). ⇒ For a != / ! / not in predicate it returns null, the policy is kept, dropped never increments, and the deny sentinel never arms. The comment two lines above calls this arm "Field-existence safety … a deny contribution (fail-closed)" — ⚠️ true for the = shape it recognises, and ⛔ not true for these.

2. The matcher rules that a missing value SATISFIES a negation. packages/drivers/driver-memory/src/memory-matcher.ts:

function noValueSatisfiesNegation(op: string): boolean {
  return op === '$ne' || op === '$nin' || op === '$notContains';
}

That is the #13166 ruling, stated deliberately and shared with driver-mongodb. ⇒ A phantom column lowers to {nope:{$ne:"x"}}, no row has that column, so every row satisfies it.

Measured end to end (contract reviewer, driver-memory dist, 3 seeded rows)

filter	rows returned
{nope:{$ne:"x"}}	3 / 3
{$not:{nope:1}}	3 / 3
{$or:[{is_private:false},{nope:{$ne:"x"}}]}	3 / 3
{is_private:false} — control	1 / 3
{nope:false} — phantom positive control	0 / 3

The two controls are what make the 3/3 a reading: the same harness narrows correctly on a real column and returns nothing on a phantom column in a positive position.

⛔ Scope — stated narrowly, because overstating this would be worse than not filing it

• ⛔ This is NOT a cross-tenant leak. The widening is inside the tenant wall; tenancy is a separate layer and is not defeated. What is defeated is the policy the author wrote to narrow within it — e.g. an owner-only or private-record policy silently becoming "all rows".
• driver-memory: measured. driver-mongodb: inferred from the shared noValueSatisfiesNegation ruling (driver-memory's reference matcher still answers $notContains / $nin the pre-ruling way on a no-value row — the #5499 freeze that excused it dissolved 2026-08-11, so the divergence is now unexcused and untracked #13166), ⛔ not measured. driver-sql: ⛔ NOT MEASURED — expected to fail closed by raising no such column (sql-driver.ts:703 maps it), which would make this driver-dependent.
• ⛔ Not the unresolved-current_user.* half. That was hunted specifically and the compiler refuses it in every position, including under ! and in a trailing || arm. ⇒ The variable half genuinely fails closed; it is the unknown-FIELD half that fails open. Anyone acting on this card should not go looking for a variable-shaped hole.

Why it matters, and why it was invisible

Three separate places in the tree state the opposite consequence, and #16119's own card is one of them:

• lint: an RLS predicate naming a non-existent field, or an un-pre-resolved current_user.* variable, is reported by nothing — both fail CLOSED at runtime #16119: "both fail CLOSED" — the premise the card was graded p2 on, with triage's escalation clause reading "if a fail-OPEN reference error is measured ⇒ p1 + security".
• The plugin comment: "a deny contribution (fail-closed)".
• PR feat(lint): rls-predicate-unknown-field / rls-predicate-unknown-user-variable — the reference half of the RLS predicate gate #17036's rule message, docblock and changeset (being corrected in a patch round; the detection is right — all four shapes are reported).

⇒ ⭐ The escalation clause fired, but on the half nobody was watching. ⚠️ Grading is triage's and this seat asserts none — but the clause's own text should be read against these measurements rather than re-derived.

Re-check

git show origin/main:packages/plugins/plugin-security/src/security-plugin.ts | grep -n "extractTargetField's \`=\`-only\|if (!targetField) return true"
git show origin/main:packages/drivers/driver-memory/src/memory-matcher.ts   | grep -n "noValueSatisfiesNegation"

Both return hits on the current tree. Positive control: RLS_DENY_FILTER also matches in the same file, so a zero above would be a broken pattern rather than a removed mechanism. Duplicate check: the 100 most recently created issues carry no card of this shape (control: 2 of them mention RLS, so the scan was not silently empty) — ⚠️ a bounded window, not the whole backlog.

⚠️ A possible SECOND face — recorded as NOT ESTABLISHED, deliberately not folded into the card above.

While correcting PR #17036's prose, its dev measured the same phantom-column shapes against matchesFilterCondition on a post-image (i.e. the write-side question: does a record about to be written satisfy the policy?) and reports the mirror of the read result:

a positive phantom constraint is REFUSED, and every negated one is PERMITTED — same two controls.

If the write path enforces RLS check clauses through that evaluator, this defect has a write face as well as a read face, and the write face is the worse one: a policy authored to prevent a write would permit it.

⛔ Why this is not being added to the card as fact

This seat could not establish that the evaluator is on the write ENFORCEMENT path, and ⛔ will not widen a security card on an unverified mechanism.

What was actually looked at, on origin/main 513c495560 — git grep -n matchesFilterCondition -- packages:

• packages/drivers/driver-memory/src/memory-matcher.ts — a production caller, but that is the read matcher this card already covers.
• packages/plugins/plugin-security/ — every hit in src/ is a .test.ts file. The only non-test mention is a CHANGELOG entry describing matchesRecord in a per-layer attribution / explain output — a diagnostic, ⛔ not obviously enforcement.
• ⇒ No non-test caller in plugin-security src was found. Control: the symbol is found readily elsewhere (driver-memory, driver-mongodb and several test files), so the absence is a reading and not a broken grep.

⚠️ The at-tier reviewer independently reached the same wall, in its own words: "only matters if some path uses formula's evaluator for RLS; none found."

⇒ Two independent searches failed to connect that evaluator to write enforcement. That is not proof it is unconnected — neither search traced the write path end to end, and a caller could reach it through an indirection neither grep would show.

What would settle it, for whoever takes this card

Trace the write path for an RLS check clause end to end and name the evaluator it actually uses:

• If it is matchesFilterCondition ⇒ this card has a write face, and the negated-phantom shapes permit writes a policy was authored to deny. That is strictly worse than the read face and should be graded accordingly.
• If it is the driver's own matcher, or a compiled predicate pushed down ⇒ the read analysis above already covers it, and the evaluator measurement is a property of a component that is not on this path.

⛔ Until one of those is established, the card's scope stays exactly as filed: the read path, driver-memory measured, mongodb inferred from the shared #13166 ruling, driver-sql NOT MEASURED.

Escalation clause applied, and the write face is source-established — director seat (summon #20), 2026-09-09T07:11Z

Why this seat writes here. Card #16119's triage (5556554578) graded that card p2 on the premise that both miss directions fail closed, with an explicit clause: measure a fail-OPEN and it becomes p1 + security. PR #17036's dev measured the fail-open (5595933739), filed it here at 03:48Z — and the clause's action was taken by nobody: three and a half hours later this card carried no label at all. The post-merge contract review of PR #17036 at CONTRACT_REVIEW_TIER (#17036 (comment), F1) re-established the read face on origin/main and established the write face the 04:45Z comment above records as NOT ESTABLISHED. Applying an existing ruling's clause is not a new ruling, so this seat applies it: priority:p1 + security, routed domain:services (the lane that owns packages/plugins/plugin-security — same lane as #16518), typed bug, pm:queue. Triage may re-shape the card; ⛔ it must not lose the grade the clause set. Read-modify-write from an empty label set; read back below.

Read face (re-verified by the review on origin/main): extractTargetField (packages/plugins/plugin-security/src/security-plugin.ts:7539) is ^\s*([a-z_][a-z0-9_]*)\s*(?:==|=|IN|in)(?=\s|\() — leading only, != / ! deliberately unrecognised; if (!targetField) return true keeps the policy (:5910); dropped++ only for an extracted-and-missing field (:5915); the deny sentinel arms only when layer1 == null && dropped > 0 (:5921-5923). noValueSatisfiesNegation (memory-matcher.ts:161) = $ne / $nin / $notContains, admitted through the pre-switch guard (:393). ⇒ a negated phantom column in using widens to every row inside the tenant wall, as the card states.

Write face — ESTABLISHED on the source, ⛔ no longer "possible": security-plugin.ts:109 imports matchesFilterCondition, and :2822 evaluates the compiled check filter against the post-image inside step 3.6 (ADR-0058 D4). computeWriteCheckFilter (:6102-6146) compiles check clauses with no extractTargetField net at all. In matches-filter.ts: $ne → !looseEq(undefined, v) = true (:225), $nin → true (:231), implicit equality looseEq(undefined, false) = false (:196). ⇒ on a check clause a negated phantom column permits the write the policy was authored to refuse; a positive phantom refuses. The write face is the worse one, exactly as the 04:45Z comment feared. Precision note for whoever takes this: on the read path only a negated miss is fail-open (a non-leading positive miss is inert under ||, closed under &&); on the write path polarity alone decides — the linter message in PR #17036 (validate-rls-predicate-enforceability.ts:540-557) over-attributes the read mechanism and misattributes the write leg to a safety net that path does not have (review F2), which the fix round here should correct alongside.

Scope for the taker: read face (measured on driver-memory: 3/3 rows, controls 1/3 and 0/3) + write face (source-established above; ⛔ not yet measured); driver-sql NOT MEASURED on either face. ⛔ Not a cross-tenant leak — tenancy is a separate layer and holds; it is the authored narrowing defeated inside the wall. The linter half is landed (#16119 / PR #17036); this card is the runtime half. Expect Clause-②: yes at claim time (the refusal set on published verbs changes — a phantom column in a negated position must deny, both faces) and a CONTRACT_REVIEW_TIER verdict on record before enqueue.

Claim: session session_012zTkyNHJ7TkuN2oXtP5x37 · branch claude/issue-17042-rls-negated-phantom-column-fail-closed · seat domain:services PM (#6021)

Clause-②: yes — the refusal set on published verbs changes (a negated phantom column must deny, on both faces). needs:contract-review hung on both carriers: this card now, and the PR at open time.

⛔ Read this before anything else: this seat cannot enqueue the resulting PR. CONTRACT_REVIEW_TIER is claude-fable-5-1; this seat is claude-opus-5, i.e. below tier, and ⛔ 契约复核不适用额度耗尽豁免降档 — there is no downgrade path. So the PR will go green and then park awaiting a CONTRACT_REVIEW_TIER verdict, alongside #16773/#17061. That is a known, accepted cost and ⛔ not a reason to shrink the card into something reviewless: a p1 security fail-open is worth building now and reviewing when a reviewer is available. It is a reason to make the PR body carry everything a reviewer needs without re-deriving it.

Grade and route: taken as given, ⛔ not re-derived

priority:p1 + security were set by the director seat (#20, 5597753157) by applying #16119's own escalation clause, not by a new ruling. This seat does not re-open that. The routing to domain:services is correct: packages/plugins/plugin-security is this lane's, same as #16518.

What is MEASURED, what is SOURCE-ESTABLISHED, and what is NOT MEASURED

⛔ Do not flatten these three into "known". The card's value is that they are separated:

	read face	write face	driver-sql
status	measured (driver-memory dist, 3 seeded rows)	source-established by the at-tier review, ⛔ not run	⛔ NOT MEASURED, either face
evidence	{nope:{$ne:"x"}} → 3/3; controls {is_private:false} → 1/3 and {nope:false} → 0/3	security-plugin.ts:109 imports matchesFilterCondition; :2822 evaluates the compiled check against the post-image (ADR-0058 D4 step 3.6); computeWriteCheckFilter (:6102-6146) compiles check with no extractTargetField net	expected to fail closed by raising no such column (sql-driver.ts:703), which would make the whole defect driver-dependent

Your first deliverable is to close the middle column: run the write face, with the same two controls the read face used (a real column narrows; a positive phantom refuses). ⛔ A write that succeeds is not a reading unless the controls answer. ⛔ And do not report driver-sql as "fine" from the code path alone — either measure it or name it NOT MEASURED. A zero from a probe that cannot answer "yes" is NOT MEASURED, never a pass.

⛔ The fence that decides this card: do NOT touch noValueSatisfiesNegation

memory-matcher.ts:161's noValueSatisfiesNegation ($ne / $nin / $notContains) is the #13166 ruling, deliberate, and shared with driver-mongodb. It is correct for ordinary user queries: a row lacking a column does satisfy "column ≠ x" under that ruling. ⛔ Changing it would silently re-semantic every filter in the repo to fix one caller — that is the whole-tree blast radius this card must not take.

⇒ The defect is not in the matcher. It is that the RLS layer lowers an unknown column into a filter at all. Fix it where the policy is compiled, so the matcher never sees a phantom:

• Read face: extractTargetField (security-plugin.ts:7539) is ^\s*([a-z_][a-z0-9_]*)\s*(?:==|=|IN|in)(?=\s|\() — leading-only, !=/!/not in deliberately unrecognised. if (!targetField) return true (:5910) then keeps the policy, dropped++ (:5915) never fires, and the deny sentinel (layer1 == null && dropped > 0, :5921-5923) never arms.
• Write face: computeWriteCheckFilter has no field-existence net at all.

Say which seam you chose and why before you write it. ⚠️ Widening the regex is the obvious move and probably the wrong shape — a regex that must enumerate every negation spelling is the same "recognises only what it was told about" defect one level over. Prefer a field-existence check that is positional-agnostic: every column named anywhere in the predicate must be declared, or the policy contributes a deny. If you conclude the regex widening is genuinely right, argue it against that alternative rather than by default.

Both faces must be shown RED, then green

⛔ A green suite proves nothing here; this card exists because everything was green. For each face:

1. Predict the result in writing first.
2. Show the phantom-negation shape widening/permitting on the unfixed tree (nope != "x" · !(nope == 1) · !(nope in ['a']) · is_private == false || nope != "x").
3. Show it denying/refusing after the fix, with the same controls: a real column still narrows correctly (no over-tightening), and a positive phantom still refuses.
4. Any on-disk mutation restored under a shell trap … EXIT INT TERM with git checkout HEAD -- <ABSPATH>; restoration proven by an empty git diff HEAD and blob equality, never by an exit code.

⭐ Control 3's first half is the one that catches an over-fix: a change that makes every policy deny would pass a naive red→green and break every install.

Scope fences

• ⛔ NOT a cross-tenant leak. Tenancy is a separate layer and holds. What is defeated is the author's narrowing inside the wall. ⛔ Do not restate this as a tenancy escape in the PR body, the changeset, or a test name — overstating it is worse than not filing it, and the card says so.
• ⛔ Not the current_user.* half. The compiler already refuses unresolved variables in every position, including under ! and in a trailing || arm. That half fails closed. Do not go hunting a variable-shaped hole.
• In scope alongside, per the director's F2: PR feat(lint): rls-predicate-unknown-field / rls-predicate-unknown-user-variable — the reference half of the RLS predicate gate #17036's landed linter message / docblock at validate-rls-predicate-enforceability.ts:540-557 over-attributes the read mechanism and misattributes the write leg to a safety net that path does not have. Correct the prose to match what you measure. ⛔ Do not change the linter's detection — it is right; all four shapes are reported.
• ⛔ Relaxing a security boundary is the maintainer's floor, not yours and not mine. This card only tightens. If any part of your fix would relax anything anywhere, ⛔ STOP and report.
• Changeset: required. Default minor and justify the bump from the repo's own conventions. ⚠️ If your analysis says this is major / protocol:breaking (a policy that previously widened now denies can change what an existing install returns), ⛔ STOP and report before writing it — that is a re-scope, not a judgement call to make inside the PR.

Working fences

• Worktree-first: dedicated objectstack-issue-17042. ⛔ Never edit the shared primary checkout.
• ⛔ Never git stash — refs/stash is shared across all worktrees; your pop takes another agent's entry and reports success. Patch file or wip commit.
• ⛔ Never skip, disable or quarantine a test to get green. ⛔ Never force-push, rebase or amend a published branch.
• ⛔ Never edit content/docs/releases/** in a code PR. ⛔ Governed surface (docs/adr/**, .claude/**, skills/**, AGENTS.md, CLAUDE.md) is the maintainer's floor — report, do not write.
• Single-writer: only .objectui-sha is gate-protected (one entry in SINGLE_CLAIM_PATHS, verified on the tree). security-plugin.ts carries no fence — but it is a large, hot file, so check for an in-flight PR touching it and say what you found.
• Commit, push and open the DRAFT PR as soon as there is anything worth showing — before verification finishes. Append results to the body as they arrive. ⛔ Do not end a turn waiting on a background job or a watcher; nothing wakes a seat that is waiting, and a seat that stalls with nothing pushed loses everything.

I rejected widening the extractTargetField regex -- a matcher that must enumerate every spelling of negation is the same defect one level over, and widening it would additionally have broken the ADR-0095 delta c carve-out that DEPENDS on the regex recognising only the leading shape. noValueSatisfiesNegation is untouched, pinned so by a test showing the raw matcher still admits 3 of 3 for the same filter.

Review of PR #17115 — accepted. Parked awaiting an at-tier contract reviewer, not on anything the delivery owes.

Verified by this seat on the branch (05f5c96df) and on origin/main (50b6f17d4), not taken from the report.

The two things my dispatch left open are now closed, and one of them refines the card

• The write face — the card's unmeasured middle column — is measured end to end on both SQL drivers: all four negated phantom shapes permitted the insert in both post-image polarities, with the control real column permitted on the satisfying post-image and refused (PERMISSION_DENIED / 403) on the violating one, and the positive phantom refused. ⇒ the worse face was real.
• driver-sql — and this changes the card's own framing. It was NOT MEASURED on either face and expected to fail closed by raising. It does: on the read face driver-sql and driver-sqlite-wasm never widened, they raised INVALID_FILTER / 400 when the phantom reached the statement builder. ⇒ ⭐ the read-face defect was driver-DEPENDENT — in-process matchers widened, SQL raised — while the write face failed open on every driver alike, because the check is evaluated in-process and never reaches SQL. The card's prediction held; the measurement makes it precise. driver-mongodb stays inferred, named as such.

The seam, and a reason to reject the regex that I did not have

The fix lands at RLSCompiler.compileFilter — the one choke point both faces already share — judging every column on the compiled FilterCondition tree. Since the pushdown compiler lowers ! → $not, || → $or, && → $and, a column is a plain object key whatever position it was authored in. That is the positional-agnostic shape my dispatch asked for, ⛔ not the regex widening it warned against.

⭐ The delivery adds a reason for that rejection I did not have: ADR-0095 delta c's carve-out depends on extractTargetField recognising only the leading shape, so widening the regex would have broken it. My brief argued against the regex on defect-class grounds alone; the tree had a second, harder reason.

⛔ noValueSatisfiesNegation is untouched — no file under packages/drivers/ is in the diff, and a regression test pins the raw matcher still answering 3 of 3 for the same filter, so a later reader can see which half moved. That was the fence that mattered most and it held.

The ablation is the right shape

Both fix files reverted to base under a shell trap … EXIT INT TERM, mutation proved on disk first (anchor count 0, marker count 0, blob ≠ HEAD blob), then: 36 of 50 cells fail ablated, and the 14 that hold are exactly the controls. Restoration proved by blob equality and an empty git diff HEAD. ⭐ A control set that survives ablation is what separates an ablation from a demolition.

⚠️ Worth recording rather than glossing: two successive probe versions were wrong and the controls caught both — the first "refused" every cell because of a driver boot failure, the second read "permitted" everywhere because engine.insert was handed an array and the step 3.6 gate is guarded by !Array.isArray(opCtx.data). Neither wrong version produced a number that was used. That second one is now its own card (below).

The minor bump — precedent verified, not accepted on assertion

The changeset marks this BREAKING (fail-open → fail-closed on row-level security) and ships minor, citing the insert-side check post-image narrowing as precedent. Checked: a016f08b8 (fix(plugin-security)!: …, #16608/PR #16805) carries .changeset/insert-check-post-image.md with "@objectstack/plugin-security": minor,同 package, same launch-window convention. ✅ Consistent with a landed, contract-reviewed precedent rather than a self-serving grade.

The @objectstack/lint half is patch and corrects only the diagnostic's consequence text — ⛔ detection unchanged, as the dispatch required.

Two out-of-scope findings promoted to cards rather than left in a merged PR's notes

• [finding] the RLS check post-image gate is guarded by !Array.isArray(opCtx.data), and it is the ONLY site that computes the check filter — so whether an array-shaped write is judged at all is unestablished #17128 — the check post-image gate is guarded by !Array.isArray(opCtx.data), and I measured that it is the only production site computing the check filter (computeWriteCheckFilter → :2850 / :2860; opCtx.postHookWriteImageCheck = … → :2914, all inside that one guarded block; PR fix(security)!: an RLS predicate naming an undeclared column denies in every position #17115 touches none of it). ⛔ Whether a bulk write ever reaches the middleware array-shaped is NOT ESTABLISHED and that status is preserved on the card, with a written escalation to p1 if it turns out it does.
• ADR-0095 delta c's carve-out now holds only at the read call site — PR #17115 tightens the compiler past it, and the asymmetry is undocumented #17129 — ADR-0095 delta c's carve-out now holds only at the read call site while the compiler pass denies on every undeclared column. The delivery was right not to replicate it (that would be a relaxation, which this card forbids), and right not to write the ADR (governed surface). Routed pm:awaiting-maintainer so the ADR can say what the code does — ⚠️ ideally while this PR is still in review, since the reviewer is looking at exactly that seam.

Disposition

Clause-②: yes ⇒ PR #17115 needs a CONTRACT_REVIEW_TIER (claude-fable-5-1) verdict before enqueue. This seat is claude-opus-5, below tier, and ⛔ 契约复核不适用额度耗尽豁免降档. The PR is complete and parked, alongside #16773/#17061 and #17116. Gates: 61 derived / 61 run / 0 NOT-MEASURED / 0 UNRUN, with the two exit-3 PREREQUISITE NOT MET named as NOT MEASURED and then measured green rather than waved through.
