Follow-up to #2759 / #2776.

Researcher #11471 identified two completion-path gaps on the original #2759 implementation:

ACTIVITY_LOGGED error branch must preserve message_id. The current implementation already extracts payload.message_id and passes it to onSendComplete/onSendError; this PR adds regression tests proving token-specific error completion and fallback behavior when message_id is absent.
Batch agent-message consume must complete every token. The current implementation already loops over consumed messages and calls onSendComplete(m.messageId) for each; this PR adds a regression test proving a two-message batch completes both tokens.

The #11470 safe no-messageId fallback (exact-one conservative) is already covered by existing useChatSend.concurrentReplies tests and remains unchanged.

Test plan

npx vitest run src/components/tabs/chat/hooks/__tests__/useChatSocket.test.tsx — 8/8 pass.
npx vitest run src/components/tabs/chat — 340/340 pass.

Follow-up to #2759 / #2776. Researcher #11471 identified two completion-path gaps on the original #2759 implementation: 1. **ACTIVITY_LOGGED error branch must preserve `message_id`.** The current implementation already extracts `payload.message_id` and passes it to `onSendComplete`/`onSendError`; this PR adds regression tests proving token-specific error completion and fallback behavior when `message_id` is absent. 2. **Batch agent-message consume must complete every token.** The current implementation already loops over consumed messages and calls `onSendComplete(m.messageId)` for each; this PR adds a regression test proving a two-message batch completes both tokens. The #11470 safe no-messageId fallback (exact-one conservative) is already covered by existing `useChatSend.concurrentReplies` tests and remains unchanged. ## Test plan - `npx vitest run src/components/tabs/chat/hooks/__tests__/useChatSocket.test.tsx` — 8/8 pass. - `npx vitest run src/components/tabs/chat` — 340/340 pass.

test(chat): regression coverage for #11471 error-path message_id + batch consume b16371930c

Researcher #11471 flagged two gaps on the #2759 follow-up:

1. ACTIVITY_LOGGED error branch must pass message_id to onSendComplete/
   onSendError so error-path completion is token-specific and does not
   fall back to the coarse legacy release when a message_id is present.
2. pendingAgentMsgs consume must complete EACH message's token by its
   message_id, not just the first.

The current implementation already handles both correctly; this commit
adds explicit regression tests so future refactors cannot silently regress
back to the old coarse behavior or single-message batch completion.

- Mock consumeAgentMessages in useChatSocket.test.tsx so it returns and
  clears per-workspace message arrays.
- Add test: error broadcast with message_id passes it through.
- Add test: error broadcast without message_id falls back to undefined.
- Add test: batch consume completes all messages by message_id.

Test plan:
- npx vitest run src/components/tabs/chat/hooks/__tests__/useChatSocket.test.tsx (8/8 pass)
- npx vitest run src/components/tabs/chat (340/340 pass)

APPROVED on head b1637193.

This is test-only and the added cases are not tautological. The ACTIVITY_LOGGED error test drives the actual socket handler branch with status: "error" and verifies both onSendComplete(message_id) and onSendError(_, message_id), so it would catch a regression that drops message_id on the error path. The legacy no-messageId case explicitly omits message_id and pins the coarse fallback argument as undefined.

The batch-consume test is also meaningful: the mocked store now implements destructive consumeAgentMessages, seeds two pending messages with distinct messageIds, and verifies both onAgentMessage and onSendComplete fire twice in order. That exercises the production loop over consumed messages, not just a mocked callback.

No security or performance surface is changed. The mocking is scoped to the hook dependencies and does not hide the branches under review. CI/all-required is green on this head.

APPROVED on head b1637193. This is test-only and the added cases are not tautological. The `ACTIVITY_LOGGED` error test drives the actual socket handler branch with `status: "error"` and verifies both `onSendComplete(message_id)` and `onSendError(_, message_id)`, so it would catch a regression that drops message_id on the error path. The legacy no-messageId case explicitly omits `message_id` and pins the coarse fallback argument as `undefined`. The batch-consume test is also meaningful: the mocked store now implements destructive `consumeAgentMessages`, seeds two pending messages with distinct `messageId`s, and verifies both `onAgentMessage` and `onSendComplete` fire twice in order. That exercises the production loop over consumed messages, not just a mocked callback. No security or performance surface is changed. The mocking is scoped to the hook dependencies and does not hide the branches under review. CI/all-required is green on this head.

Post-merge audit on landed head b16371930c0d3fc100f2c27702ee4435b31beb35 (PR was already merged before my reviewer-2 pass completed): clean.

I verified the change is test-only in canvas/src/components/tabs/chat/hooks/__tests__/useChatSocket.test.tsx and the assertions are not tautological:

The ACTIVITY_LOGGED error test drives the captured socket handler through the real status === "error" branch and verifies message_id reaches both onSendComplete("msg-a") and onSendError(..., "msg-a").
The legacy test omits message_id and pins the intended undefined fallback, preserving mixed-version behavior.
The batch-consume test uses the mock store's destructive consumeAgentMessages() implementation and seeds two distinct messageId values, proving the hook completes every consumed message rather than only the first.

CI on the merged head was green for CI / all-required, CI / Canvas (Next.js), and E2E Chat. No residual issue found.
