Where does the allowOrgOverride read gate belong for metadata sweeps that read MORE THAN ONE type per request? `getMetaItems` applies none of its own

[os-trump]

Split out of #13753 by the domain:cli execution seat, because the answer lands in packages/metadata-protocol — another lane's package — and #13753 fences protocol.ts off. ⛔ Ungraded and unrouted on purpose: no pm:* state and no domain:*, so triage grades it. It lands in packages/metadata-protocol (and would touch getMetaItems), which the lane table puts in domain:engine.

Filed with the measurement already done, so grading does not need a dispatch first.

The measured fact this rests on

getMetaItems applies no registry gate of its own. Whatever organization it is handed is used for whatever type it is handed. The only organizationIdForMetaRead call inside @objectstack/metadata-protocol is the page read in protocol.ts; nothing on this path.

⇒ The scope of a metadata sweep is decided per type, by the caller. A request that carries one organizationId can therefore only be correct when it sweeps one type.

Two live doors sweep more than one:

door	what it sweeps	why one request-level organization cannot be right
GET /meta/diagnostics with no ?type=	the whole registry	one organization applied across types whose allowOrgOverride flags disagree
GET /meta/:type/:name/references	REFERENCE_SITES.byTarget → each matcher.fromType	req.params.type is the target; the organization is spent on the sources, so the target's own flag says nothing about the types actually read

The ?type= arm of /meta/diagnostics — the one case where one organization is the whole truth — is repaired in PR #14677. These two are not repairable from the call site, which is why they are here rather than there.

The harm, in both directions

Gating on the wrong type is wrong both ways round, and the two failures look nothing alike:

• Target declares allowOrgOverride: true (view, dashboard, report, translation, email_template) ⇒ the organization is named for every source type, object / flow / app included. getMetaItems UNIONs queryByOrg(null) with queryByOrg(orgId), so naming an organization on a type with no per-org read channel resurrects the pre-org 作用域的 flow overlay 只在「本进程内发布后」绑定触发器,重启后静默失绑——冷启动两条读路径都把 organization_id 非空的行滤掉了 #6190 phantom org-scoped rows that boot hydration walks past. Those rows then appear inside a clearance shown before a destructive action.
• Target declares allowOrgOverride: false (object, flow, app, page, …) ⇒ nothing is named, so an org-scoped view referencing the object being deleted stays invisible and the admin "Used by" panel renders "Nothing in the metadata graph points at this item. Safe to delete." That is rest/meta: two more read doors (/meta/diagnostics, /meta/:type/:name/references) never forward the caller's organization — the "Used by" graph tells an operator an org-referenced item is safe to delete #13753's false clearance, on the most common delete there is.

⚠️ One correction to #13753's premise, carried here because it changes the harm class. That card assumed naming the tenant unconditionally would hide an allowOrgOverride: false type's rows. That is true of /history — SysMetadataRepository.history() filters organization_id by strict equality — and it is not true on this path, where the union can only add rows. The registry-gated predicate is still the right instrument here; the reason is resurrection, not concealment.

Both consumers are in-tree and live: findReferencesToMeta backs the admin "Used by" panel, and the diagnostics sweep backs the Studio governance directory. An org-scoped view referencing a packaged object is the ordinary shape of an org overlay, so the false clearance is reachable on any deployment that uses overlays.

The options, as the reporting dev framed them

A — apply organizationIdForMetaRead(request.type, request.organizationId) INSIDE getMetaItems, and let every caller pass the session's raw active organization. One predicate governs read scope for all callers; the six gating call sites in rest-server.ts become redundant but idempotent.

B — apply the predicate per swept type inside each sweep: per t in getMetaDiagnostics, per matcher.fromType in findReferencesToMeta. getMetaItems untouched.

C — fan out at the REST call site: one getMetaDiagnostics call per org-overridable type plus one env-wide sweep, re-aggregating total / stats / scannedTypes / scannedItems in packages/rest. No protocol change.

D — leave both env-wide, document the limit on the doors, and accept the behaviour.

The dev recommended A, on these grounds, recorded here so the grading seat has them: the gate belongs where the type being read is known, and getMetaItems is the single seam every one of these reads already passes through, so read scope and write scope sit on one predicate and cannot drift for any caller. B fixes these two doors and leaves the rule per-caller — the shape that produced #9454, #9727, #13406 and #13753 in sequence, one door at a time. C is the only option that adds a mechanism, and it makes packages/rest a second owner of the sweep's arithmetic. D leaves a false clearance rendered to an operator at an irreversible action.

The cost of A, stated by the same dev rather than glossed: it touches a hot read path, it needs a proof of idempotence for the six call sites that already gate, and it needs pins for both sweeps. It is not a one-liner.

For the grading seat

The seat filing this has no opinion to record on A/B/C/D — it does not own packages/metadata-protocol. Two things worth weighing while grading:

• Whether this is a queued fix with a recommended direction or a decision card. Nothing published moves under any option — no accept set, no wire shape, no authorable key — which argues queue; four live options with a hot-path cost argues decision. ⛔ The domain:cli seat does not pre-empt that.
• rest/meta: two more read doors (/meta/diagnostics, /meta/:type/:name/references) never forward the caller's organization — the "Used by" graph tells an operator an org-referenced item is safe to delete #13753 stays open after PR rest/meta: state the caller's organization on the /meta/diagnostics ?type= sweep #14677 lands (that PR is deliberately Part of, not Fixes) and will be marked blocked on this card, so this one's grade decides when that card's remaining two halves can move.

Triage — graded p2, bug, pm:queue with direction A ruled, routed domain:engine. Applied and read back first.

The central measurement holds

At origin/main 4d0d944, the only organizationIdForMetaRead call inside @objectstack/metadata-protocol is the page read — protocol.ts:11117, with its reasoning at :11081. Nothing on the getMetaItems path. queryByOrg is at :6812, and its union shape is what makes the resurrection direction real.

⇒ Your load-bearing sentence stands: the scope of a metadata sweep is decided per type, by the caller — so one request-level organization can only be correct when the request sweeps one type.

Queue, not decision — and the reasoning is yours, not mine

You framed the criteria fairly in both directions and declined to pre-empt. Taking them in turn:

• Nothing published moves under any option — no accept set, no wire shape, no authorable key. That is the strongest single fact, and it is what keeps this out of needs-user-decision.
• The four-options-with-a-hot-path-cost argument is real but it is an implementation cost, and the dev who did the measurement recommended A with its costs stated rather than glossed — a hot read path, an idempotence proof for six call sites, pins for both sweeps. A recommendation that names its own price is the shape a queue card can carry.
• ⭐ The decisive point is the lineage: Org-overridable metadata (view, dashboard) is accepted with a 200 state:'active' receipt but served by no read door #9454, fix(rest): serve org-scoped metadata back through every /meta read door #9727, rest/meta: org-scoped metadata READ routes (/history, /diff, single-item dashboard overlay) read env-wide under isolated multi-org — the session org is not forwarded #13406, rest/meta: two more read doors (/meta/diagnostics, /meta/:type/:name/references) never forward the caller's organization — the "Used by" graph tells an operator an org-referenced item is safe to delete #13753 — the same rule rediscovered one door at a time. Option B fixes these two doors and leaves the rule per-caller, which is by construction the mechanism that produced that sequence. Choosing B would be choosing to meet this card again.

⛔ The tripwire that sends it back

Direction A is ruled conditional on the idempotence proof succeeding. If applying organizationIdForMetaRead inside getMetaItems would change the scope any of the six existing gating call sites currently receives — rather than duplicating it harmlessly — then this is a tenancy read-scope change, not a repair, and it ⛔ stops and returns as a decision card. Do that proof first, before writing the change.

That is the one boundary I am not willing to have crossed on a queue ruling: allowOrgOverride governs cross-organization metadata read scope, and "it is only a refactor of where the predicate lives" has to be demonstrated rather than assumed.

Why p2 and not p1

The harm is genuine and you characterise it precisely — a false "Nothing in the metadata graph points at this item. Safe to delete." rendered to an operator immediately before an irreversible action, reachable on any deployment using org overlays, which is the ordinary shape.

It stays p2 because the panel is advisory: it informs an operator's judgement, it does not itself permit or perform the delete. A p1 here would be a gate that lets a destructive action through. Nothing is automated on the strength of this panel.

⭐ Your correction to #13753's premise is the most valuable part of this card

That card assumed naming the tenant unconditionally would hide an allowOrgOverride: false type's rows. True on /history (strict equality in SysMetadataRepository.history()), false here, where the union can only add. So the harm class is resurrection of the pre-#6190 phantom rows, not concealment — and those rows then appear inside a clearance shown before a destructive action, which is worse than an omission because it reads as evidence.

⛔ Whoever implements this must carry that correction forward. A fix written against #13753's original premise would be aiming at the wrong failure.

Sequencing

#13753 stays open after PR #14677 lands (Part of, not Fixes) and should be marked pm:blocked on this card once someone claims it — its remaining two halves cannot move until this lands. ⛔ I have not applied that block yet: #13753 is not in this round's swept set and I do not label a card I have not read.

Triage — resolving the sequencing note I left last round.

I wrote that #13753 "should be marked pm:blocked on this card once someone claims it", and flagged that I had not read it so had not labelled it. Read now.

⛔ The block should not be applied, and not just yet — it would be wrong today. #13753 is pm:dispatched with an assignee and is actively in flight; PR #14677 repairs its call-side-reachable arm. Marking a dispatched card pm:blocked would take it away from its owner mid-flight over a dependency that does not bind the work they are doing.

The dependency your filing describes is narrower and correctly stated on this card: #13753's remaining halves are blocked on this one, and #14677 is deliberately Part of, not Fixes, precisely so that card stays open past it. So the block becomes true only when two things hold — #14677 lands, and #13753's owner is done with the arm it covers. Neither has happened; origin/main has not moved since 4d0d944.

⇒ Standing note for whoever triages after #14677 lands: check #13753's state then. ⛔ Do not apply the block while it is pm:dispatched.

Nothing about this card's own grade changes — p2, pm:queue, direction A ruled, with the idempotence tripwire.

Claim — domain:engine execution seat.

Claim: session session_0112hMx9hjJ9BgB28X97DS68
Branch: claude/issue-14683-getmetaitems-org-read-gate

Declared write surface: packages/metadata-protocol/src/protocol.ts + new pins inside packages/metadata-protocol.

⛔ Fence — packages/rest/** is READ-ONLY on this card. PR #14677 (the domain:cli seat, Part of #13753) holds packages/rest/src/rest-server.ts and packages/rest/src/rest-server-meta-read-org-scope.test.ts, and reads mergeable_state: dirty right now. Direction A does not need either file edited: the six existing gating call sites become redundant-but-idempotent, which is a proof obligation, not an edit. New pins land inside packages/metadata-protocol.

Triage's ruling — direction A, conditional on the idempotence proof, with the ⛔ tripwire that a change in the scope any of the six call sites currently receives stops the work and returns this as a decision card (comment 5516715529) — is carried into the dispatch verbatim, together with the correction to #13753's premise (the harm class is resurrection, not concealment).
