fix(chat): store a delivered reply before announcing it#6037YellowSnnowmann wants to merge 5 commits into
Conversation
An interactive reply reached disk only if the viewing client persisted the `chat_done` it received, which made the renderer the single writer of an answer the core had already produced. One failed `threads_message_append`, one socket reconnect (a new `client_id` leaves only the `thread:<id>` room as a route), or one webview reload during a long turn, and the reply was gone from the thread while the agent's own session history still held it. `deliver_response` now writes an unsegmented reply under `agent:<request_id>` before it publishes the terminal event, the way `task_session::append_final` already did for autonomous turns, and the client's append collapses onto that row because both derive the same id. The workspace rides on the turn result rather than being re-read at delivery, so an account switch mid-turn cannot file a reply under whoever is signed in when it happens to finish. A segmented delivery is excluded: the client owns one row per segment there, so the core stores none. Two client-side gaps that made a lost event permanent are closed with it. A failed append now re-reads the thread instead of only logging, which surfaces the core's copy without the user re-asking. And a reconnect rejoins the rooms of the threads a disconnect orphaned and re-reads them, so a turn that finished during the gap is not invisible until the thread is reselected. Closes tinyhumansai#6034

ChatRuntimeProvider so that when refetch succeeds but the expected reply remains
absent after both persistence attempts, it dispatches the existing user-visible
delivery error or retry state before returning instead of only calling
console.error. Ensure the subsequent finishChatDoneTurn flow cannot present a
completed turn with no reply.
- Around line 1591-1612: Update the reconnect healing effect and
socketService.subscribeThread flow so subscribeThread reports whether it
actually emitted; only remove each thread from interruptedThreadsRef after a
successful subscription, and retain failed thread IDs for the next connection.
Ensure loadThreadMessages is triggered only after subscription succeeds,
allowing retries when the socket is not truly connected.

…ministic Review found the core row is the one the reader ends up with: the client's append is deduped onto it and the cache takes whatever the store returns, so a row carrying only scope and request id silently dropped citation chips — on screen and after reload. The stored row now carries the turn's citations under the same key the client would have written, and the doc comment says why any field added there belongs here too. Recovery gets two fixes it was missing. `thread:subscribe` is acknowledged server-side and the client awaits that ack before re-reading the thread, so the read can no longer land before the socket is in the room and miss a reply announced a moment later; a core that never acks falls back to the previous unordered behaviour on a timeout rather than stalling. And a thread whose join never emitted, because the socket dropped again, stays in the interrupted set instead of being cleared, so the next connection retries it rather than stranding it until the user reselects the thread. A reply that neither writer stored is now a user-visible notice (`reply_delivery_failed`) rather than a console line. An in-thread message was not an option: writing one needs the same append that just failed. Closes tinyhumansai#6034

Pushed Fixed
Answered, not changed
Verification — Rust |
`subscribeThread`'s resolved value decides whether the runtime re-reads a thread and whether it keeps that thread queued for the next connection, and the provider tests mock the module out entirely — so nothing covered the ack, the bounded wait for a core that never acknowledges, or the disconnected case that must leave the thread queued rather than emitting.

interruptedThreadsRef.current. A thread retained after an unsuccessful room join is removed when a later disconnect tracks a different active thread.

Add a regression test for a failed join on thread A, followed by a disconnect with thread B active.

The subscribe acknowledgement was hardcoded to true, so a failed `socket.join` still told the client it was in the room. The client uses that answer to stop queueing the thread for retry and to read on the strength of the room, which reproduces the invisible reply this room exists to prevent. `join_room_logged` now reports the outcome and the handler sends it; the two log-only call sites ignore it explicitly. Also corrects two translations: `récupérée` rather than the literal `relue` in French, and `riletta` to agree with `risposta` in Italian.

Summary
agent:<request_id>before it publisheschat_done, extending the core-persists-first contract fix(chat): persist autonomous replies once under a core-owned id #5956 established for autonomous turns to interactive and forked ones.chat_doneappend reuses that id, so the two writers collapse onto one row instead of leaving a duplicate answer (Bug: Agent response renders twice in chat — once in bubble, once as duplicate plain text below #5933).threads_message_appendnow re-reads the thread instead of only writing a debug log, so the core's copy renders without the user re-asking.Problem
An interactive reply reached disk only if the viewing client persisted the
chat_doneit received. The core wrote nothing on that path —presentation.rssaid so explicitly, pointing attask_session::append_finalas the thing autonomous turns do instead. That made the renderer the single writer of an answer the core had already produced, and three ordinary events lost it outright:addInferenceResponseis not optimistic — the row enters the cache only in thefulfilledreducer,rejectedis a no-op, and the only handling wasrtLog('chat_done_append_failed'), which is dev-only. The streamed preview is cleared synchronously just before, so the answer left the screen and never reached disk.client_id, so only thethread:<id>room can still reach the client — and the provider clears every active-thread marker on disconnect, which is exactly the listsocketServicere-subscribes from, leaving only the selected thread rejoined.finishChatDoneTurnrefetches usage, the user snapshot and the turn-state timeline, never the thread's messages.loadThreadMessagesruns on thread selection only.The agent's own session transcript still held the reply, which is why the reported symptom was "the agent says it answered and I see nothing", and why re-asking made it reappear.
Solution
deliver_responsetakes the workspace the turn ran in and calls the newweb_chat::reply_persistence::persist_delivered_replybeforepublish_chat_done. The id isrun_reply_message_id(request_id), the sameagent:shape the conversation store's idempotency lookup keys on, so the client's later append returns the stored row rather than adding a second one.Design decisions worth reviewing:
deliveredReplyMessageIdmirrors that exclusion on the client, so segments keep generated ids. Worth knowing while reading:deliver_responsesetslet segments = [full_response.to_string()]unconditionally today, so the segmented branch is dead on this path — the split is defensive, not hypothetical dead weight.workspace_diris carried onWebChatTaskResult, not re-read at delivery. Re-resolving config after the turn would file the reply under whichever workspace is current when it finishes; a sign-out or account switch moves that path.chat_errorkeepscorePersistedMessageId(system-only). Widening the deterministic id to failures would let a success row already stored under that id swallow a later failure row for the same request.None.finalize_flow_streamhas no config in scope, so flow turns keep the pre-existing client-only behaviour rather than growing a config load on that path.Submission Checklist

Desktop only; no migration, no config, no new dependency. On-disk shape changes for interactive replies: the row is now written by the core with a deterministic
agent:<request_id>id instead of by the client with a UUID. Row count per turn is unchanged — the client's append collapses onto it — and both writers usesender: "agent", which is what title generation and every renderer key on. Threads written before this keep their existing ids and are unaffected.One added write per turn on the delivery path, into a store already serialised behind
CONVERSATION_STORE_LOCK; the client's subsequent append now takes the idempotency lookup, which is a raw-line scan gated on theagent:prefix (the path #5956 added and measured).Related
