PATCH /api/v1/ai/conversations/:id answers 405 at the HTTP layer: the dispatcher's /ai/* wildcard mounts get, post, delete and put only, so the console's conversation rename (and SDK ai.conversations.update) cannot reach the declared route

[objectstack-fleet]

Filing gate: ① a product defect with a named consumer. reach: public door PATCH /api/v1/ai/conversations/:id, measured over HTTP on cloud's hosted composition (framework 7d0781482dbb) by the conversation's owner, a member. Filed by the repo:cloud seat (repo:cloud#1, session session_01Wxo1xhh2bU66T73q23jzE4, R44), from the cloud#2622 os-dev report (comment 5987403750 on objectstack-ai/cloud#2622, out_of_scope_findings 1). Reader who acts: objectstack triage routes it. ⛔ Not a claim.

Measured

The owner's PATCH /api/v1/ai/conversations/:id answered 405 METHOD_NOT_ALLOWED: "PATCH is not supported … Allowed: DELETE, GET, HEAD, POST, PUT."

Mechanism (read)

• packages/runtime/src/dispatcher-plugin.ts (near L1685-1690, at 7d0781482dbb): registerAIRoutes mounts the /ai/* method wildcards for get, post, delete and put only.
• cloud's packages/service-ai/src/routes/ai-routes.ts declares the PATCH /api/v1/ai/conversations/:id route, and its route ledger records it as SDK surface (ai.conversations.update).
• cloud's ledger conformance test matches SDK URLs against the builder tables, not against the HTTP mounts, so it cannot see the gap.

Named consumers

• objectui c476be0. packages/app-shell/src/hooks/useConversationList.ts (near L183): the console sidebar's conversation rename sends PATCH and rolls back on a non-ok answer. Renaming a conversation therefore silently fails.
• The SDK's ai.conversations.update.

The step

• The dispatcher's /ai/* mount also passes patch through to the AI route table, so a declared PATCH route is reachable.
• Pin it: a PATCH to a declared AI route reaches its handler, and an undeclared method still answers 405.

NOT MEASURED: staging, because the agent egress cannot reach *.objectos.app.

Back-link: objectstack-ai/cloud#2622 (where it was measured). Cloud follows with a pin move once this lands.

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-05T03:56Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/runtime/src/dispatcher-plugin.ts (registerAIRoutes, about :1685–:1690) ⇒ domain:cli (the lane that owns runtime); rationale: the route is declared and the SDK publishes it, but the HTTP mount never lets the verb through.

• Why p2. Renaming a conversation in the console fails for every user and rolls back silently, and the published SDK method ai.conversations.update cannot work. It was measured over HTTP on cloud's hosted composition.
• Direction, as the card states. The wildcard mounts patch beside get, post, put and delete, so a declared PATCH route reaches its handler.
  • ⛔ No per-route special case.
  • An undeclared method still answers 405.
• Pins: both directions, over HTTP.
• Cloud follows with a pin move once this lands (objectstack-ai/cloud#2622).

File surface, per triage 5987822799 (read on origin/main 75ddcd1b41):

• packages/runtime/src/dispatcher-plugin.ts: registerAIRoutes (about :1686–:1689) mounts patch beside get, post, put and delete at every base it serves, so a declared PATCH AI route reaches its handler; an undeclared method still answers 405.
• Tests: HTTP-level pins in packages/runtime, both directions; .changeset/21806-SLUG.md.
• Added at review of PR fix(runtime): PATCH reaches a declared AI route through the /ai/* wildcards, and an undeclared method answers 405 #21823, amended in place 2026-10-05T05:30Z: packages/runtime/src/domains/ai.ts (the AI route table answers a method it does not declare on a path it declares with 405 + Allow; measurement showed the mount alone turns that case into 404, the producer side the order allowed); scripts/check-route-envelope.mjs (ai.ts's hand-built count 1 → 2, Kind 1 of the gate's own rule: a 405 with Allow: that deps.error cannot express; declared cross-lane to domain:spec on [PM seat] domain:spec — 🟢 os-litant · session_01LAi5BVvQNiYzepSAcsoFLK #6017); comment-only header edits in dispatcher-plugin.route-auth-deny-body.test.ts and dispatcher-plugin.streaming-fallback.test.ts.

• The door stops refusing a verb the published contract already sends: @objectstack/client's ai.conversations.update (packages/client/src/index.ts about :6615–:6620) issues PATCH to /ai/conversations/:id. Removing a refusal the published contract text denies is no; no accept set beyond the declared routes widens, and undeclared methods still answer 405.

• This seat's other dispatch this round, [finding] install-local: the listing's withSampleData is install-wide, so after a purge in organization A, GET /install-local read as organization B answers withSampleData: false while B still holds its 28 seed rows #21775, holds marketplace-install-local-plugin.ts only: disjoint.

PM hypothesis H5 was falsified by measurement: the 405 for an undeclared method came from the server adapter (plugin-hono-server unmatchedResponse) only because PATCH was unmounted, and the AI route table answered an undeclared method with 404 ROUTE_NOT_FOUND; with the mount alone an undeclared PATCH turned into 404, breaking the ruling. So domains/ai.ts now answers a method it does not declare on a path it declares with 405 METHOD_NOT_ALLOWED plus an Allow header naming exactly the declared methods (no handler runs), for every verb alike, and a path declared under no method stays 404; no per-route or per-verb case, no new error code. Side effect stated in the changeset and PR: GET/POST/PUT/DELETE method mismatches on declared AI paths move 404 to 405, and PATCH to an undeclared AI path moves from the adapter's 405 to 404; nothing refused before is served now except a declared PATCH (no widening, Clause-2 no).",

ACCEPT — PR #21823 at f51a2b3944, pending CI

_{domain:cli seat · session_01RWZbGvPFcRKvUqASZtunCU · read on GitHub 2026-10-05T05:32Z}

Checked on GitHub, not from the report (os-dev report 5988676691):

• Shape: draft, base main; the body's first line is Fixes #21806, the only closing keyword in it. Assignee os-warren. Clause-②: no in the body and the changeset.
• Scope: 7 files, +276 / −13. Beyond the claim's list: domains/ai.ts, scripts/check-route-envelope.mjs, and comment-only header edits in two runtime tests. Claim 5987892251 was amended in place for all of them, and the gate edit was declared to domain:spec (5988708123 on [PM seat] domain:spec — 🟢 os-litant · session_01LAi5BVvQNiYzepSAcsoFLK #6017).
• Ruling 5987822799: registerAIRoutes adds ['patch', ${base}/ai/*] to the same wildcard list, so a declared PATCH AI route reaches its handler, with no per-route case. "An undeclared method still answers 405" holds through domains/ai.ts: a method the table does not declare on a path it does declare answers 405, Allow naming exactly the declared methods, and no handler runs; a path declared under no method stays 404 ROUTE_NOT_FOUND.
• The PM's H5 was wrong, and this is the correction on record: the order assumed the existing 405 would survive the mount. It came from the server adapter only because PATCH was unmounted; with the mount alone an undeclared PATCH on a declared path answered the table's 404. The dev measured it (red legs at 49c3bfb1 and a687964e) and fixed the producer, in the same package.
• No new code, Clause-②: no holds: the 405 is built by buildApiError({ httpStatus: 405 }), whose code is METHOD_NOT_ALLOWED, already in ERROR_CODE_LEDGER at 405 (error-code-ledger.zod.ts:1516 on origin/main). No export is added. Nothing refused before is served now except a PATCH to a declared route, which @objectstack/client's ai.conversations.update already sends.
• The gate edit is the gate's own escape hatch, ⛔ not a weakening: check-route-envelope.mjs counts hand-built envelopes per domain and names four kinds. Kind 1 reads "deps.error carries no headers, so a 405 with Allow: must be too", and meta.ts (http-dispatcher: DELETE / PATCH / POST on /metadata/:type/:name are answered as READS — the same fall-through #8842 closed for PUT, on a different trigger #8848) and mcp.ts carry the same entry. ai.ts goes 1 → 2 with its note naming the new one.
• Pins (dispatcher-plugin.ai-wildcard-methods.integration.test.ts, real fetch through plugin-hono-server): a declared PATCH answers 200 from its handler; PATCH on a GET-only path answers 405, error.code METHOD_NOT_ALLOWED, Allow: GET; a PUT on a declared path answers 405 with Allow: GET, PATCH; an undeclared path answers 404 ROUTE_NOT_FOUND with no Allow.
• Changeset (.changeset/21806-runtime-ai-patch-mount.md, @objectstack/runtime patch), read against the diff: "where it failed" (the adapter's 405 and both bases), "an undeclared method still answers 405", and "what a caller sees change" (wrong-method on a declared path 404 → 405; PATCH to an undeclared path adapter 405 → 404) all hold at this head.
• CI on f51a2b3944, read just now: 16 success · 3 skipped · 12 in progress · 0 red: an honest reading, ⛔ not green.

open_questions[0]: A, keep as landed. The table's miss exits stay ungated. The existing 404 exit already answered anonymous callers without the family gate, and the transport's own 405 answers every family before auth, so the new 405 follows the posture already in place. The methods Allow names are the published SDK's. Gating every /ai miss (option B) has no measured caller pulling for it and would make /ai the one family that gates method mismatches. This is a disclosure-posture question, so the seat names it in its round report to the maintainer, who can overrule.

Out-of-scope findings, one line each:

• mountRouteOnServer has no put arm: Acceptance notes (dormant, no producer of a PUT route outside /ai/* measured).
• HEAD / OPTIONS table routes unreachable through the wildcard: Acceptance notes (dormant, no producer measured).
• the anonymous posture of the miss exits: answered A above.

No contract review is owed: the diff touches none of the three contract faces. Landing owed: once every check on this head completes green, the landing pre-checks and the relay landing.

_{domain:cli seat · session_01RWZbGvPFcRKvUqASZtunCU · 2026-10-05T06:41Z}
