* ⚡ feat: Immediate Conversation Title Generation Generate conversation titles as soon as the request is made (in parallel with the response, from the user's first message) as the new default, fixing the #13318 race where a transient /gen_title 404 left new chats stuck on "New Chat". - Add per-endpoint `titleTiming` ('immediate' | 'final') to baseEndpointSchema; `endpoints.all` acts as the global default, unset = immediate. Resolve via a new `resolveTitleTiming` helper (`all` takes precedence). - Fire title generation in parallel with `sendMessage`; `titleConvo` waits (bounded, abortable) for the agent run and titles from the user input only. Persist after the conversation row exists; defer `disposeClient` until the title settles. - Expose `titleGenerationTiming` via startup config; `useTitleGeneration` fetches eagerly in immediate mode with a bounded 404 retry and never treats a transient 404 as final. Skip title queueing for temporary conversations. - Supersedes #13329 while incorporating its bounded 404-retry. * 🩹 fix: Address Copilot review findings on title timing - Guard against an undefined conversationId in addTitle (skip + warn) so the gen_title cache key can't collide as `userId-undefined` and saveConvo is never called without a conversationId. - Gate the title `useQueries` on `enabled` so no /gen_title request fires while unauthenticated (e.g. after logout) even if the module queue holds IDs. - Drop the stale `conversationId` param from the titleConvo JSDoc. - Add a regression test for the undefined-conversationId guard. * 🧵 fix: Harden immediate-title edge cases from codex review - Cancel in-flight immediate title generation when the request aborts: thread job.abortController.signal through addTitle so pressing Stop on a new chat neither consumes the title model nor surfaces a title for a cancelled turn. - Preserve a locally-applied title when the final SSE event's conversation carries no title yet (built before the title was saved), so long immediate-mode responses no longer revert the chat to "New Chat" until reload. - Guarantee one full post-completion gen_title fetch cycle before giving up, so a `final`-mode title (generated only after the stream ends) is still fetched under a global `immediate` default instead of being stranded. - Add regression tests for the abort propagation and the undefined-conversationId guard. * 🔁 fix: Correct title abort, post-completion refetch, and replacement ordering Follow-up to codex review of the immediate-title fixes: - Use a dedicated title AbortController instead of `job.abortController`. The latter is also aborted by `completeJob` on *successful* completion, which cancelled any title slower than a short response. The title is now cancelled only on a real user Stop or when the stream is replaced; a completed-then- aborted title is discarded (no save, cache cleared) rather than persisted. - Reset (not remove) the post-completion title query: `resetQueries` refetches the mounted observer with a fresh retry budget, whereas `removeQueries` left it stuck in its error state, so the promised post-completion cycle never ran. - Run the job-replacement check before resolving `convoReady`, and on a replaced stream cancel/discard the stale title so a discarded prompt can't persist a title. * 🧷 fix: Tighten title abort ordering and endpoint-level timing resolution Follow-up to codex review: - Abort the title controller before resolving `convoReady` on a stopped turn, so the title task can't resume and persist before the later abort. - Cancel the title and unblock its waits on ANY send failure (not just user aborts): a preflight/quota failure before the run exists otherwise hangs `_waitForRun`, deferring client disposal until the 45s title timeout. - Resolve `titleTiming` for custom endpoints via `getCustomEndpointConfig` (their config lives under `endpoints.custom[]`, not `endpoints[endpoint]`). - Derive the startup `titleGenerationTiming` via `resolveTitleTiming` for the agents endpoint so an endpoint-level `final` (without `endpoints.all`) is honored client-side instead of defaulting to immediate and burning eager gen_title polls. * 🪢 fix: Per-agent title timing and safer abort/replacement handling Follow-up to codex review: - Resolve `titleTiming` from the agent's actual endpoint after initialization, so a per-endpoint `final` override on a custom/provider endpoint backing an (ephemeral) agent is honored instead of always using the `agents` endpoint's value. - Don't preserve a locally-fetched title on a stopped (unfinished) turn: the server cancels and discards that title, so keeping it client-side would diverge from server state and leave the stopped chat titled until reload. - On abort/replacement, only delete the cached title if it still holds THIS task's value — a replacement stream shares the `userId-conversationId` key and may have already cached its own valid title that must not be removed. * 🪞 fix: Mirror AgentClient title-config resolution for titleTiming Per maintainer guidance, keep titleTiming resolution identical to how `AgentClient#titleConvo` already resolves the endpoint config — `endpoints.all` is the intended global override and the agent's actual provider endpoint is used: - Resolve via `endpoints.all ?? endpoints[endpoint] ?? getProviderConfig(endpoint) .customEndpointConfig` (was using `getCustomEndpointConfig` directly). Going through `getProviderConfig` picks up its case-insensitive fallback for normalized provider names (e.g. `openrouter` → `OpenRouter`), so a custom endpoint's `titleTiming` is honored like its other title settings. - Add `titleTiming` to the Azure endpoint schema `.pick()` so `endpoints.azureOpenAI.titleTiming` is no longer silently stripped by Zod. Note: per-endpoint title settings being skipped when `endpoints.all` is present is the existing, intended global-override behavior — not changed here. * 🧪 test: Cover useTitleGeneration effect logic (integration) Adds a deterministic white-box integration test that drives the real hook's React effects with a controllable react-query surface, locking down the stateful decisions that previously had no coverage: - immediate mode fetches a queued conversation while its stream is still active - final mode gates until the stream completes, then becomes eligible - success applies the fetched title to the conversation caches - a 404 while active defers (removeQueries) instead of giving up - a 404 after completion forces a fresh fetch via resetQueries (post-completion remount) * feat: Stream immediate title events * style: Format title SSE handler * test: Preserve data-provider exports in OAuth mock * test: Isolate OAuth route API mock * test: Keep OAuth callback factory capture * fix: Replay streamed title events on resume * fix: Honor agents title timing precedence * style: Format title timing fixes |
