MUL-5150: add project context to Chat (#5765)
* feat(chat): add project context Co-authored-by: multica-agent <github@multica.ai> * fix(chat): resolve MUL-5150 review blockers - Renumber project-context migrations to unique prefixes after current main: 206_chat_session_project -> 212 (column), 207_chat_session_project_index -> 213 (concurrent index). 206/207 collided with 206_agent_disabled_runtime_skills and main's 207-211 client_usage_daily set. - Add the 4 missing chat input.project_context keys to ja/ko locales so the locale parity test passes (en/zh-Hans already had them). - Lock the project-context control while a send is in flight (isSubmitting), not just while the agent is running. A brand-new chat creates its session lazily during send bound to the project at click time; switching project mid-send would create the session against the stale project and clear the editor as if the send landed on the new selection. Add a regression test. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: multica-agent <github@multica.ai> * fix(chat): complete project context handling * fix(chat): pin fresh chat to open session's agent on project switch Switching an existing session to a different project opens a fresh chat but only cleared the active session, dropping selection back to the stored `selectedAgentId`. When that preference was stale (open session belongs to agent B while the persisted pick is still agent A), the lazily-created session and its first send bound to the wrong agent (agent A). Extract the project-switch decision into a shared `planProjectContextChange` pure helper in use-chat-controller.ts and route both chat surfaces (the chat tab controller and the floating ChatWindow) through it, so the fresh chat is pinned to the open session's agent and the rule cannot drift between the two copies. Add a dual-entry regression test (pure-fn guard + controller integration) covering the stale selectedAgentId case. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: multica-agent <github@multica.ai> * chore(ci): re-trigger required checks on latest head The prior push updated the branch ref but GitHub did not emit a pull_request synchronize for it (PR head-sync lag), so CI/Mobile Verify never ran on the commit carrying the stale-agent project-switch fix. Empty commit to force a fresh synchronize on a head that includes it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: multica-agent <github@multica.ai> * fix(chat): renumber project migrations to 213/214 after main added 212 Current main added 212_agent_service_tier; the PR's 212/213 chat migrations collided with it on the merge ref, failing TestMigrationNumericPrefixesStay UniqueAfterLegacySet. Merge current main and move the chat column migration to 213 and the concurrent index migration to 214 (column before index preserved). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: multica-agent <github@multica.ai> * fix(chat): lock ProjectPicker clear control during send (keyboard path) The send-pending lock only put pointer-events-none on the wrapper, which blocks the mouse but leaves ProjectPicker's inline clear button in the tab order — a keyboard user could Tab to "Remove from project" and press Enter mid-send, detaching the project after the lazily-created session already went out with the old one (reopens the mid-send retarget path via keyboard). Add an explicit `disabled` capability to the shared ProjectPicker that locks the trigger, the menu (forced closed), and the inline clear button (disabled + out of the tab order). Defaults to false, so issue/create/autopilot callers keep their hover/keyboard clear. ChatInput passes disabled while the project selection is locked. Tests: real-ProjectPicker regression (keyboard activation of the clear control is inert when disabled; still works when enabled) + ChatInput wiring assertion that the picker is disabled mid-send.

MUL-4864 fix(chat): use a single New Chat draft, keyed by session not agent (#5519)
* fix(chat): use a single New Chat draft, keyed by session not agent (MUL-4864)
An uncreated chat kept one draft per agent (`__new__:<agentId>`), so
switching the agent picker mid-compose swapped the draft out from under
the user and left invisible per-agent drafts behind. That slot shape was
never a product decision: it fell out of

fix(chat): defer cancellation-time finalization until the task transcript is stable (#5246)
A quick Stop before the agent's first token no longer races a late reply. Started-but-empty cancellations defer the empty/non-empty judgment until the daemon acks its transcript flush (or a grace-period sweeper fires), then settle to a single outcome. Empty outcomes persist a durable, creator-authorized draft restore (fetched/consumed via a dedicated endpoint, reconnect-safe and at-most-once) instead of broadcasting the prompt over the workspace bus. Closes #5219 |

feat(chat): Chat V2 — first-class IM-style Chat tab (MUL-4171) (#5076)
* feat(chat): Chat V2 — first-class IM-style Chat tab (MUL-4171) Replace the floating chat FAB/window with a first-class Chat tab under Inbox, laid out as an IM-style two-pane surface (thread list + conversation). Highlights: - New Chat page (packages/views/chat/chat-page.tsx) with URL-addressable session selection; web + desktop routing wired up. Removes the old chat-fab / chat-window / resize-handles / context-items paths. - IM thread list: agent avatar + last-message preview + IM timestamp, red unread *count* badge (read-cursor model), presence-gated typing vs waiting. Rename lives only in the conversation header ⋯ menu (not the list hover). - Per-session conversation header (rename / view agent / delete), agent-aware empty state (avatar + name + description + starter prompts), and a deterministic clean-title derivation from the first message. - Server: read-cursor unread model (migration 145) and per-user pinned agents (migration 146, dedicated chat_pinned_agent table + handler/queries). New-agent welcome chat auto-enqueues a real agent run (LLM intro, no static template). - Design: fade the global --border token; borderless list headers on Chat/Inbox, kept (faded) on the conversation header. Verified: pnpm typecheck (all packages), go build ./..., go vet, gofmt. Co-authored-by: multica-agent <github@multica.ai> * feat(chat): make new-agent welcome read as an agent-initiated intro (MUL-4230) The "meet your new agent" chat used to insert a fake user message ("👋 Hi! Please introduce yourself …") and have the agent reply to it, so the thread looked like the creator prompting the agent. Drop the persisted user message. Flag the auto-created session is_agent_intro (migration 147) and drive the intro run server-side: the daemon builds a proactive self-introduction prompt for such sessions (buildChatPrompt) instead of a "reply to their message" prompt. The intro stays LLM-generated; the thread now opens with the agent's own message, as if it reached out first. - migration 147: chat_session.is_agent_intro - CreateChatSession carries the flag; sendAgentWelcomeChat no longer persists/publishes a user message - daemon: ChatIntro threaded from session flag → intro prompt Co-authored-by: multica-agent <github@multica.ai> * feat(chat): Settings toggle for the floating chat window (MUL-4235) (#5080) * feat(chat): Settings toggle for the floating chat window (MUL-4235) Re-introduce the floating chat overlay on top of Chat V2 as an optional, Settings-gated surface instead of deleting it outright. - Settings → Preferences → Chat: a switch (floatingChatEnabled, persisted client preference, default ON) to show/hide the floating window. - FloatingChat wrapper owns the two gates: the preference, and the /chat route (hidden on the tab so the same activeSessionId isn't shown twice). - ChatFab + a compact ChatWindow that reuse the shared useChatController and conversation components, so activeSessionId stays in lockstep with the tab. - Restore use-chat-context-items so the overlay's @ surfaces the current issue/project (the 'current context' affordance) — the tab stays manual. - i18n (en/zh-Hans/ja/ko), store unit tests. typecheck: core/views/web/desktop green. tests: chat store 9, settings 82, chat 39 pass. Co-authored-by: multica-agent <github@multica.ai> * feat(chat): dedicated Chat settings tab, floating window opt-in (MUL-4235) Address review: give Chat its own Settings tab instead of a section inside Preferences, and default the floating window OFF (opt-in). - New Settings → Chat tab (chat-tab.tsx) under My Account; moves the floating-window toggle out of the Preferences tab. - floatingChatEnabled now defaults OFF — only an explicit enable from the Chat tab mounts the FAB/overlay. - i18n: page.tabs.chat + a top-level chat block (en/zh-Hans/ja/ko); revert the Preferences chat section and its test mock; store tests updated for the opt-in default. Co-authored-by: multica-agent <github@multica.ai> --------- Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * refactor(chat): drop starter prompts from chat empty state (MUL-4237) (#5081) The three starter prompts (List my open tasks by priority / Summarize what I did today / Plan what to work on next) read as filler more than help, so remove them along with the now-unused returning_subtitle ("Try asking"). The empty state keeps its agent-aware header — avatar + "Chat with {name}" + optional description — and the composer stays the entry point. Locale keys dropped across en/zh-Hans/ja/ko (parity preserved). Based on the Chat V2 branch (parent MUL-4171, #5076), not main. Co-authored-by: Lambda <lambda@multica.ai> * feat(chat): pin a chat to the top of the Chat list (MUL-4240) (#5082) Builds on Chat V2 (#5076). Adds a per-conversation pin so a user can keep important chats at the top of the IM-style thread list, above the activity-sorted rest. Backend: - migration 148: chat_session.pinned_at (nullable) + partial index; the timestamp doubles as the pinned-group sort key and the boolean flag. - list queries order pinned-first, then by most-recent activity. - SetChatSessionPinned query + PATCH /api/chat/sessions/{id}/pin handler; pinning never bumps updated_at, so an unpinned chat won't jump the list. - ChatSessionResponse.pinned + chat:session_updated carries the new state. Frontend: - ChatSession.pinned; setChatSessionPinned API + useSetChatSessionPinned with optimistic re-sort; shared sortChatSessions comparator. - thread list: pin indicator on pinned rows + pin/unpin hover action; list sorted pinned-first so it stays ordered after cache patches. - realtime patch re-sorts on pin change; en/ja/ko/zh-Hans strings. Tests: SetChatSessionPinned handler test, sortChatSessions unit tests. * feat(chat): round send button, move file upload into a + menu (MUL-4250) (#5088) Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * fix(inbox): match chat list selected-item style (inset padding + rounded) (#5093) Wrap the inbox list in p-1 and give each row rounded-md/px-3 so the selected bg-accent reads as an inset rounded card — same treatment the chat thread list already uses — instead of a full-bleed, sharp-cornered highlight. Content stays 16px-inset (p-1 + px-3 == old px-4). MUL-4253 Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * fix(chat): rename + menu upload item to "Image or files" (MUL-4250) (#5092) Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * fix(chat): stop welcome intro session repeating the same introduction (MUL-4259) The is_agent_intro flag on chat_session is persistent, so every follow-up turn on a welcome session re-selected the self-introduction prompt in buildChatPrompt and the agent kept replying with the same intro instead of answering the user. Gate resp.ChatIntro at claim time on the session still having zero human (role='user') messages via a new ChatSessionHasUserMessage query: the first, message-less server-driven turn introduces the agent; once the creator replies, later turns fall back to the normal reply prompt. Co-authored-by: multica-agent <github@multica.ai> * fix(chat): address review findings + unbreak CI (MUL-4171) - task:failed now refreshes the sessions list (invalidateSessionLists), so the thread-list preview / unread / sort stays correct after an agent failure — FailTask persists a failure chat_message but only broadcasts task:failed, mirroring the chat:done success path. - Self-heal stale chat deep links: once the sessions list has loaded and a ?session= id isn't in it (deleted / no access / never existed) with nothing in flight, clear the selection instead of rendering an editable empty chat that would POST into a nonexistent session. Freshly-created sessions are exempt (they carry optimistic messages + a pending task). - CI: add the new parameterless `chat` route to link-handler's WORKSPACE_ROUTE_SEGMENTS and to paths/consistency.test.ts (route set + expectedSegments) — keeps the two in sync, fixes the failing @multica/core test. - Fix a MUL-4235/MUL-4237 merge collision that broke @multica/views typecheck: chat-window.tsx still passed the removed `onPickPrompt` prop to EmptyState. Co-authored-by: multica-agent <github@multica.ai> * fix(chat): self-heal dangling session in shared controller, not just ChatPage (MUL-4171) Re-review follow-up: the stale-session self-heal only lived in ChatPage, so the floating ChatWindow still entered from a persisted activeSessionId and would render an editable empty chat (then POST into a nonexistent session) when the selected session was deleted / lost access off the /chat route. - Move the self-heal into the shared useChatController so every surface (tab and floating window) drops a dangling activeSessionId once the sessions list has loaded and doesn't contain it. - Harden ensureSession: trust the current id only when it's in the loaded list or is a just-created session still awaiting the refetch; a dangling id falls through to create a fresh session instead of POSTing into a 404. - Exempt just-created sessions via an OPTIMISTIC-write signal (hasOptimisticInFlight: pending task or optimistic- message), not hasMessages — a session deleted elsewhere with real cached history stays eligible for self-heal. Add a unit test for the discriminator. Co-authored-by: multica-agent <github@multica.ai> * test(views): fix app-sidebar useWorkspacePaths mock for the new chat nav (MUL-4171) The AppSidebar personal nav gained a `chat` item, so it calls `useWorkspacePaths().chat()` at render. The app-sidebar.test.tsx mock hadn't been updated, so `p.chat` was undefined and every render threw `TypeError: p[item.key] is not a function`, failing @multica/views#test in CI. - Add `chat: () => "/acme/chat"` to the mocked useWorkspacePaths. - Route the chat-sessions query key through a mutable `chatSessions` fixture. - Add coverage for the Chat nav: renders the link, badges the summed unread_count, and hides the badge when all sessions are read — so this drift is caught next time. Co-authored-by: multica-agent <github@multica.ai> * fix(chat): use the original floating window, not the rewritten one (MUL-4235) (#5102) Follow-up to the merged #5080, which shipped a hand-written, simplified ChatWindow and lost the original's animations / drag-resize / expand-minimize. The floating window is just a quick entry point — it should be the original UI, not a rewrite. - Restore chat-window.tsx, chat-fab.tsx, chat-resize-handles.tsx and use-chat-resize.ts verbatim from main (0-diff): motion animations, drag resize, expand/minimize and the session dropdown are back. - Restore the empty_state.returning_subtitle + starter_prompts i18n keys the original window renders (V2 had dropped them); drop the now-unused window.open_full_tooltip key the rewrite added. - Settings gating is unchanged: FloatingChat still wraps the original FAB + window, gated by floatingChatEnabled (default off) and hidden on /chat. typecheck: core/views/web/desktop green. tests: chat + settings views 126 pass. Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * feat(chat): archive chats from the list, delete only from Archived (MUL-4263) (#5098) Restore an archive flow as the reversible sibling of delete: - Chat list hover now offers Archive (not Delete); pin/stop unchanged. - A footer entry ('Archived · N') opens an Archived view listing archived chats; hard delete lives only there (hover -> unarchive + delete, with the existing inline confirm). - Conversation header ⋯ menu mirrors this: active chats archive, archived chats unarchive/delete. Backend: PATCH /api/chat/sessions/{id}/archive flips status active<->archived (SetChatSessionArchived), broadcasts status on chat:session_updated so other tabs re-sort into the right list. SendChatMessage already refuses archived sessions, so archived chats stay read-only until unarchived. Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * feat(chat): handle archived agents in Chat V2 list & conversation (MUL-4265) (#5100) * feat(chat): handle archived agents in Chat V2 list & conversation (MUL-4265) Co-authored-by: multica-agent <github@multica.ai> * refactor(chat): drop chat-list archive marker, keep conversation read-only (MUL-4265) Co-authored-by: multica-agent <github@multica.ai> * feat(chat): apply archived-agent read-only to the floating chat window (MUL-4265) Co-authored-by: multica-agent <github@multica.ai> --------- Co-authored-by: Lambda <lambda@multica.ai> Co-authored-by: multica-agent <github@multica.ai> * fix(chat): address floating-window + archived-agent review blockers (MUL-4171) Re-review follow-up on the restored floating ChatWindow + archive flow: 1. Floating stale-session self-heal. The restored ChatWindow doesn't use the shared controller, so its ensureSession trusted any non-empty activeSessionId and there was no dangling-session cleanup — a deleted / no-access persisted session could send into a nonexistent session. Ported the same guard used for the tab: a self-heal effect that clears a dangling activeSessionId once the sessions list has loaded, and ensureSession only trusts an id that's in the list or has an in-flight optimistic write (hasOptimisticInFlight, reused from use-chat-controller). handleSend seeds the optimistic message + pending task before setActiveSession, so a freshly-created session is never mis-cleared. 2. Floating dropdown bypassed archive-first safety. Its active rows offered a hard-delete, letting the floating window destroy active chats and skip the "archive first, delete only from Archived" model. Active rows now ARCHIVE (reversible, one-click) like ChatThreadList; the floating window offers no hard-delete — unarchive/delete live only in the full Chat page's Archived view (reachable via expand). Removed the now-dead delete-confirm machinery. 3. Orphan user message on archived-agent send. SendChatMessage created the chat_message before EnqueueChatTask, which rejects an archived / runtime-less agent — a stale client would land a user message then get a 500, orphaning it. Added a preflight that checks the session agent's archived / runtime state and returns 409 before any mutation, plus a handler test asserting the send is rejected with no message persisted.

feat(chat): workspace-scoped attachment binding + fire-and-forget send (#4249)
* feat(chat): workspace-scoped attachment binding + fire-and-forget send Uploads are now workspace-scoped: the chat session is created and attachments are bound to the message at send time, so a paste/drop no longer creates an empty session the user never sends. - LinkAttachmentsToChatMessage returns the ids it actually bound; the client diffs requested-vs-bound and warns on partial bind, replacing an extra listChatMessagesPage fetch. - Cancelling an empty chat task detaches attachments before deleting the user message (attachment FK is ON DELETE CASCADE) and returns them via cancelled_chat_message.attachments, so a restored draft can re-bind. - SendChatMessageResponse.attachment_ids has no omitempty: "requested but bound zero" serializes [] so the client can tell it apart from an older server and still warn. - Send is fire-and-forget: it no longer steals focus when the user has navigated to another session (guarded on the live store + new-chat agent id); the reply surfaces via the unread dot. commitInput gets clearEditor so a navigated-away commit doesn't wipe the editor now showing another session, while still clearing the sent draft's data. - Draft restore is session-aware so a failed fire-and-forget send restores into the session it was sent from, never the one the user moved to. - Removed the now-unreferenced migrateInputDraft store action. Verified: core/views typecheck, chat-input (15) / store (3) / api client (24) unit tests, go build + vet, handler SendChatMessage + CancelTaskByUser DB tests. Full make check / E2E left to CI. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(chat): guard attachment survival on empty-chat cancel Cancelling an empty chat task deletes the user message, and attachment.chat_message_id is ON DELETE CASCADE (migration 083), so the detach-before-delete in finalizeCancelledChatMessage is the only thing keeping the user's attachment from being silently destroyed. Nothing covered it. Add a DB regression test that binds an attachment to the cancelled user message and asserts: the row survives the cascade (chat_message_id NULL, chat_session_id retained), the cancel response returns it via cancelled_chat_message.attachments, and a resend re-binds it to the new message. Verified red when the detach step is removed. Related issue: MUL-3364 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Co-authored-by: multica-agent <github@multica.ai> * fix(comment): pessimistic submit for comment/reply composers The comment and reply composers cleared the editor after `await onSubmit` returned, with no in-flight lock. On a slow send the WS `comment:created` event already dropped the real comment into the timeline while the box still held the same text + spinner, so it read as two comments. And because `submitComment`/`submitReply` swallow errors (toast, no rethrow), a failed send still reached `clearContent` and silently discarded the user's draft. Recover the comment/reply portion of the closed #4236: make the submit callback resolve a success boolean (true on success, false on the caught failure), lock the editor while in flight (pointer-events-none + dimmed wrapper + aria-busy, since ContentEditor can't toggle Tiptap `editable` post-mount), keep the button spinning, and clear only on success — a failed send keeps the draft. Chat composer is out of scope (already reworked on this branch); attachment binding is untouched. Adds two view tests (in-flight lock then clear-on-success; failed send keeps the draft); both verified red against the un-fixed code.

fix(editor): don't wipe in-flight uploads on external content sync (#4196)
* fix(editor): don't wipe in-flight uploads on external content sync When a brand-new chat's first file upload triggers lazy session creation, `setActiveSession(null → uuid)` flips ChatInput's draft key mid-upload, which changes `defaultValue` to the new (empty) session draft. ContentEditor's "sync external defaultValue" effect then ran `setContent` over a document that still held the `uploading` image/fileCard node, wiping it — so the upload's finalize could no longer find the node. The file vanished and the draft was left with an empty `!file[name]()`. The editor was never remounted (instance stays alive); the node was removed by the content-sync effect. An uploading node is local state an external sync must not overwrite, exactly like the existing dirty/focused guards. Add a guard that bails the sync while any `uploading` node is present. Pure frontend; affects only the first upload in a new chat (subsequent uploads hit an existing session, so no draft-key flip). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(editor): cover the in-flight-upload content-sync guard The content-sync effect now reads `editor.state.doc.descendants` on every run to detect uploading nodes; the mocked editor didn't implement it, crashing all ContentEditor tests. Add `descendants` (driven by `editorState.uploadingNodes`) to the mock and a regression test asserting an external `defaultValue` change does not setContent while an upload is in flight, and resumes once it settles. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(chat): migrate new-chat draft onto the session id on lazy create The first file upload in a brand-new chat lazily creates the session, flipping ChatInput's draft key from `__new__:agent` to the session id mid-upload. The in-progress (empty-href) file-card markdown the editor had already written into the `__new__:agent` draft was neither migrated nor cleared, so it stayed stranded under that key — and resurfaced as a stale `!file[name]()` the next time a new chat opened for the same agent (the send only cleared the session-keyed draft). Migrate the `__new__:agent` draft onto the new session id the moment the session is created (upload path only — text send already clears the pre-flip key via `keyAtSend`). Add a shared `newSessionDraftKey` helper so ChatInput and ensureSession agree on the slot name, and a `migrateInputDraft` store action.
