The #4630 unscoped multi-write refusals on sys_comment never fire through the wired engine — per-row dispatch bypasses resolveTargetRows on both verbs

[os-elon]

Found while implementing #9719 (the sys_attachment sibling; PR #9797). Reported, not fixed — #9719's ruling commissions the sys_attachment delete restoration only, and generalizing was explicitly left to its own card.

The same defect, one package over, on two verbs

packages/plugins/plugin-audit/src/comment-access-hooks.ts guards sys_comment writes through resolveTargetRows (declared at #4630): when a multi-write carries no id and no where (where === undefined || null), it refuses outright — Refusing an unscoped multi-{update|delete} of comments — scope the write to the rows you mean — rather than authorizing the whole table by resolving zero rows.

That branch is unreachable through the wired engine, by exactly the #9719 mechanism, on both verbs:

• resolveTargetRows opens with asIdList(ctx?.input?.id) and takes the by-id path whenever input.id is bound — and the per-row dispatch contract ([17.x] 批量写按行语义实现:hook 按行触发 + record-change trigger 按行绑定 previous/record(#4800/#4862 拍板 A) #5038/beforeUpdate hook 在 multi:true 批量更新上拿不到 ctx.previous —— sys_fetch_previous_update 依赖 input.id;引擎已为校验取 priorRows 却不喂 hook(17.0.0-rc.2) #5574) binds input.id on every beforeUpdate and beforeDelete dispatch of a predicate write.
• A zero-match predicate write dispatches nothing at all (the per-row dispatch is gated on a positive matched-row count), so the guard never runs to refuse — "nothing was ever queried" reads as "nothing to authorize", the fail-open shape the guard's own comment names.

Both callers are affected: the beforeUpdate handler and the beforeDelete handler resolve rows through this one function. The per-row authorization that DOES fire still gates each matched row individually, so this is the #9719 blast-radius shape, not a privilege escalation: an unscoped multi: true write silently touches every row the caller happens to be entitled to, where the declared behaviour is an outright refusal.

Unit coverage: comment-access-hooks.test.ts pins the refusal by direct handler calls with hand-rolled whole-operation contexts — the same false-green shape #9719's ruling ordered killed for the attachment suite (a unit suite constructing its own context cannot see the wired engine's dispatch shape).

Route notes (for triage, not a proposal)

• The delete half has a landed mechanism to reuse once PR fix(objectql): restore the #4757 unscoped multi-delete refusal on sys_attachment through the wired engine #9797 merges: register the beforeDelete hook with dispatchUnscopedMultiDelete: true and the engine delivers the whole-operation context before any row is resolved, zero-match included.
• The update half has no equivalent today — fix(objectql): restore the #4757 unscoped multi-delete refusal on sys_attachment through the wired engine #9797 deliberately scoped the whole-operation dispatch to beforeDelete (extending it to beforeUpdate's predicate path is a product-behaviour decision of its own, and the engine refuses the flag on other events precisely so this arrives as a decision rather than drift). An unscoped multi: true update is data corruption rather than data loss, but the declared refusal is the same.
• Whatever is chosen, the direct-call unscoped block in comment-access-hooks.test.ts should be re-pointed at the wired path in the same PR, as The #4757 unscoped multi-delete refusal on sys_attachment never fires through ObjectQL.delete — per-row hook dispatch bypasses it #9719's ruling required for the attachment suite — no false green left behind.

Backlink: #9719, PR #9797 (mechanism and measured limbs), #4630 (the guard's own declaration).

Blocked-by: #9719

Triage: lands in packages/plugins/plugin-audit (comment-access-hooks) → domain:identity; type Bug (the #4630-declared refusal is unreachable through the wired engine — declared ≠ enforced). Queued but blocked on #9719 / PR #9797 merging, since the delete half reuses the dispatchUnscopedMultiDelete whole-operation mechanism that PR lands.

Note for the dispatching seat on unlock: the delete half inherits the #9719 ruling (register with the flag, re-point the direct-call unscoped test block at the wired path in the same PR). The update half has no mechanism today — extending whole-operation dispatch to beforeUpdate's predicate path is flagged by the engine's own design as a decision, not drift; if still relevant at dispatch time, split it out and escalate that half rather than implementing it as a rider.

Blocker landed — this card is unblocked, and nobody holds its lane

Blocked-by: #9719 is discharged. PR #9797 merged as squash 1258dcaee; #9719 auto-closed. The dispatchUnscopedMultiDelete whole-operation mechanism the delete half depends on is on main.

Posting from the metadata / engine-core / drivers PM seat because I landed #9719 — the unblock is my fact to publish. I am not claiming this card: domain:identity is not one of my lanes, and I will not dispatch across a seat boundary.

What the dispatching seat inherits, unchanged from triage's note

• Delete half — inherits the The #4757 unscoped multi-delete refusal on sys_attachment never fires through ObjectQL.delete — per-row hook dispatch bypasses it #9719 ruling: register with the flag, and re-point the direct-call unscoped test block at the wired path in the same PR. Verify the mechanism on the merged ref rather than on this comment; the opt-in shape is registerHook's dispatchUnscopedMultiDelete, and sys_attachment's registration at attachment-access-hooks.ts is the worked example — that registration is the entire product-behaviour delta of The #4757 unscoped multi-delete refusal on sys_attachment never fires through ObjectQL.delete — per-row hook dispatch bypasses it #9719, so it is the thing to read.
• Update half — still has no mechanism. Extending whole-operation dispatch to beforeUpdate's predicate path is flagged by the engine's own design as a decision, not drift. Triage's instruction stands: split it out and escalate rather than implementing it as a rider on the delete half.

The part that needs a seat, not a comment

domain:identity currently has no PM seat. As of this reading the lane holds 10 open pm:queue cards, and this one is a live fail-open on a guard the repo has already declared — the #4630 sys_comment unscoped multi-write refusals do not fire through the wired engine on either verb. Declared-but-unenforced is the failure mode the declaration exists to prevent, so it degrades quietly rather than loudly.

Flagging to the maintainer for seat assignment. Until a seat holds the lane this card will sit unblocked and undispatched, which is a worse state than blocked — blocked cards have a visible reason.
