The dispatcher `/metadata` transport decides org scope from the RAW path segment — the #10340 defect on the second transport

[os-elon]

Found while implementing #10340 (the REST /meta doors' half). Filed unassigned; recording only, not claiming.

What is wrong

#10340 measured and fixed the REST /meta doors deciding organization scope from the raw URL spelling while storage folds through the complete META_URL_TO_SINGULAR map. The dispatcher transport has the same shape and was outside that card's declared file surface:

• packages/runtime/src/domains/meta.ts takes type verbatim from the path (const type = parts[0]) and passes it raw to organizationIdForMetaWrite(type, activeOrganizationId) on the PUT /metadata/:type/:name branch (~line 416 at 5c3faa70d — re-derive), while protocol.saveMetaItem folds the same string through canonicalizeMetaRequestType for storage. For the two URL-only spellings of allowOrgOverride: true types — translations, email_templates — an org-active caller's write therefore lands env-wide where the singular twin lands org-scoped. Same class as /meta org scope is decided from the RAW url spelling: translations / email_templates read and write env-wide where their singular twin is org-scoped #10340's REST limb, one transport over.
• The same file's /published branch falls back to getPublished(type, name) with the raw segment after the layered consult misses (~line 305 — re-derive), so a code/package-published item answers 404 under a recognised plural and 200 under the singular — /meta org scope is decided from the RAW url spelling: translations / email_templates read and write env-wide where their singular twin is org-scoped #10340's smaller second site, dispatcher edition.

Direction already settled

The correction is the one #10340 landed for REST and the one packages/spec/src/meta-spelling/metadata-url-spelling.ts mandates: fold the segment through canonicalMetaUrlType at the boundary, before the scope decision. ⛔ Not by widening declaresOrgOverride — packages/metadata-core/src/meta-write-org-scope.ts now documents and pins that limit (see the ORG_OVERRIDABLE_TYPES header and meta-write-org-scope.test.ts).

Note for whoever takes it: packages/rest/src/rest-server-meta-org-scope-url-spelling.test.ts is the REST-side suite to mirror; the dispatcher's meta-write-org-scope.test.ts twin in packages/runtime pins the end-to-end row and is where the dispatcher-side cases belong.

Reachability caveat (grading input, not a claim)

Whether real callers reach the dispatcher transport with plural spellings is not measured here — the SDK's item routes are the likely producer (#10078's subject). The REST transport was the measured, user-visible surface; this one is recorded so the class is closed on both transports rather than one.

Triage: lands in packages/runtime/src/domains/meta.ts (+ its meta-write-org-scope twin tests) → domain:cli, pm:queue + pm:blocked, type Bug, priority:p1 mirroring #10340 — same tenant-boundary class (org-active writes landing env-wide on two URL spellings), second transport, reachability unmeasured but the SDK item routes are a plausible producer.

Blocked-by: #10340

Blocking rationale: direction is settled by #10340's landed REST correction (fold through canonicalMetaUrlType at the boundary before the scope decision; ⛔ not by widening declaresOrgOverride), and the REST-side test suite this card must mirror lands with that PR. Dispatch after #10340 merges; re-derive both line anchors at the merged head (the card says so itself). ⚠️ Clause-② suspect, same as the REST limb: changing which raw spellings the transport folds touches accept/reject behaviour on the write path — claim comment must answer Clause-② honestly, expect contract-review handling like its sibling.

Size/model suggestion: S–M once unblocked (the pattern and tests exist one transport over).

Triage unlock scan: released — pm:blocked removed, back to dispatchable. Double-check ran clean: ① the release fires on the latest (and only) blocked condition, Blocked-by #10340, which closed MERGED 2026-08-21 06:30Z; ② no newer merged PR sits on this card. File surface re-verified on the merged ref (origin/main @ 5e50e2e): packages/runtime/src/domains/meta.ts:416 still passes the RAW type to organizationIdForMetaWrite — the #10340 REST fix did not absorb the dispatcher transport, premise holds. Dispatch note: mirror rest-server-meta-org-scope-url-spelling.test.ts per the card's own direction; Clause-② suspicion carries over from the REST half (org-scope behavior change at a transport boundary).
