The live timeline was rendered in a separate <div> from the persisted
messages list. When the streamed task finished and its ChatMessage
landed, the live <div> unmounted and a new <MessageBubble> mounted —
two different DOM elements showing the same content. useAutoScroll's
ResizeObserver + MutationObserver fired on both the unmount and the
mount, causing the visible jump-then-re-render.
Merge the two paths: inject a synthetic assistant message with the
pending task_id while streaming, and key every assistant bubble by
task_id. When the real message arrives (same task_id), React preserves
the DOM element across the invalidate → refetch window — no remount,
no double scroll, no flicker.

The ChatInput wrapper toggled between pb-8 (empty state) and pb-4
(has messages), causing a 16px vertical jump the moment hasMessages
flipped. EmptyState already centers itself inside flex-1, so the
extra padding wasn't needed — collapse to a single pb-4.

* feat(chat): Chat V2 — sidebar entry + main-area page
Replace the floating drawer + FAB with a first-class workspace route
`/:slug/chat`. Sidebar gets a single `Chat` entry under Inbox with an
unread dot; session history lives inside the Chat tab via a popover
rather than leaking into the global sidebar (keeps Multica's "nouns in
the nav" semantic — Inbox / Issues / Projects are work objects, Chat is
a tool).
- Add `paths.workspace(slug).chat()` + update link-handler route set.
- New `ChatPage` view with PageHeader, history popover, centered
messages/composer column, and empty-state starter prompts.
- Delete `ChatWindow`, `ChatFab`, resize helpers, and standalone
`ChatSessionHistory` (history now embedded in the popover).
- Drop `isOpen`/`toggle`/`showHistory`/resize fields from `useChatStore`
— the page is a route now, not an overlay.
- Wire the new `/chat` route on web (App Router) and desktop
(react-router + tab-store icon mapping).
Addresses MUL-1322.
* fix(chat): align composer width with message column
The ChatPage wrapper added px-4 on top of ChatInput's own px-5, making
the composer 32px narrower than the messages column. Drop the outer
px-4 so both share the same max-w-3xl outer + px-5 inner padding
provided by ChatMessageList / ChatInput.
* fix(chat): taller default composer (~3 lines visible, 8 max)
min-h 4rem → 7rem, max-h 10rem → 15rem. Empty state previously
showed only 1 text row after pb-9 for the action bar; raise the
floor so there's visible writing room and lift the ceiling so a
longer draft can grow before scrolling kicks in.
* fix(chat): restore anchor + in-flight indicator + cold-start session restore
Three issues surfaced by review:
1. ContextAnchorButton always disabled on /:slug/chat — useRouteAnchorCandidate
only matches issue/project/inbox pathnames, so moving chat to its own route
dropped 'bring the page I was on into the conversation'. Track the last
anchor-eligible location globally (new useAnchorTracker mounted in AppSidebar
+ lastAnchorLocation on useChatStore) and substitute it when on /chat.
2. No global 'Multica is working' cue after ChatFab deletion. Subscribe the
sidebar Chat entry to pendingChatTasksOptions and swap the unread dot for a
spinner while any chat task is in flight.
3. ChatPage restore effect latched didRestoreRef before the sessions query
resolved, so cold-start direct nav to /chat landed on the empty state even
when the server had an active session. Wait for isSuccess before locking
the ref.
* fix(chat): clear lastAnchorLocation on workspace rehydration
The pathname captured in workspace A would otherwise be reused against
workspace B's wsId, triggering a cross-workspace issue/project fetch
and silently leaking anchor context into chat messages.

The focus toggle was only disabled when focusMode was already ON
*and* the current page had no anchor. Off-state on the same page
stayed clickable — clicking turned it on, and the button instantly
greyed out, making the missing fourth state visible.
Decouple "clickable" from focusMode: the button is disabled whenever
the current page has no anchor, regardless of the persisted on/off
preference. Both the chip render (context-anchor.tsx:173) and send
path (chat-window.tsx:176) already guard on candidate presence, so
leaving focusMode=true on an unanchorable page has no side effects —
the preference is preserved for the next anchorable page.
Tooltip now reads "Nothing to share with Multica on this page"
whenever the button is disabled, regardless of focusMode.

* refactor(views): extract IssueChip shared primitive from mention card
IssueMention (in editor NodeView) and IssueMentionCard shared 95% of their
markup — StatusIcon + identifier + title inside a bordered chip. They drifted
into two parallel implementations so changes had to be made in two places.
Extract the presentational chip into IssueChip. The navigable variants
(IssueMentionCard, the editor NodeView) become thin shells that layer
routing + cmd/shift behaviour onto the shared chip.

* feat(chat): add focus mode to share current page as context
Adds a Focus button next to the chat submit. When on, the chat auto-attaches
whatever the user is viewing (issue, project, or inbox-selected issue) as a
context prefix on outgoing messages, so the agent knows what "this" refers
to without the user pasting ids.
The attached object is derived from the route + react-query cache on every
render — no separate copy in state. Only the boolean focusMode is persisted
(global to the user, not per-workspace), matching the "my preference"
mental model.
The button has three visual states driven by two dimensions (focusMode +
whether the current route resolves to an anchorable object):
- off: ghost + muted, click turns on
- on + anchor: secondary (bright), click turns off
- on + none: disabled (nothing to attach here)
The derived anchor renders above the input as a chip — IssueChip for issues,
a new ProjectChip for projects — wrapped in AppLink so the visual target
matches the clickable target (mirrors IssueMentionCard's hover + navigation).
Prefix format reuses the editor's mention markdown:
Context: [MUL-1](mention://issue/<uuid>) — "Fix login bug"
Context: Project "Authentication"
so the agent sees an identical token whether the user @-mentioned inline or
focus-mode attached. Backend is untouched.

* fix(sidebar): stabilize useQuery default arrays to prevent render loop
Inline `= []` defaults on `useQuery` return a new array reference on
every render when `data` is undefined (query disabled or mid-load).
Downstream effects/memos that depend on the value then fire every
render; the pinned-items `useEffect` compounds this by calling
`setLocalPinned` each time, so under sustained `data === undefined`
(e.g. backend unreachable, WebSocket in reconnect loop) React trips
its "Maximum update depth exceeded" guard and the sidebar becomes
unusable.
Use module-level empty-array constants so the default identity stays
stable across renders.
* fix(chat): short-circuit ResizeObserver update when bounds unchanged
The resize observer always called `setRevision(r => r + 1)` from its
callback, even when `clientWidth`/`clientHeight` were identical to the
previous reading. Any spurious notification — sub-pixel layout jitter
during mount, or an ancestor reflow triggered by an unrelated state
update — then fed back into the same render cycle and could exceed
React's update-depth limit.
Guard the state bump by comparing against the previous bounds, and
leave `setBoundsReady(true)` outside the guard since it's idempotent.
Switching to a session whose messages aren't cached showed the empty
state (starter prompts) for the ~300ms the fetch took — jarring, because
you're clicking into an existing conversation, not starting a new one.
Now there's a three-branch render: skeleton while loading, empty state
for real new-chat (activeSessionId === null), messages when ready.
Cached switches still return data synchronously — no flash.

- Wrap ChatMessageList and ChatInput in mx-auto max-w-4xl px-5 so wide
chat windows don't sprawl — matches the issue-detail / project-detail
width convention
- draftKey now includes the selected agent id in the new-chat state.
Tiptap's Placeholder only applies at mount, so key-driven remount is
the simplest way to refresh it when the user switches agents before
sending the first message. Side benefit: per-agent new-chat drafts.

State management
- Pending task / live timeline are now Query-cache single source;
Zustand mirror removed (fixes duplicate assistant render caused by
the invalidate→refetch race window)
- WS subscriptions moved from ChatWindow to global useRealtimeSync so
pending state survives minimize and refresh
- New GET /chat/sessions/:id/pending-task to recover live state on mount
- Drafts persisted per-session (was per-workspace)
Unread tracking
- Migration 040: chat_session.unread_since (event-driven; old chats
stay clean — no mass backfill)
- POST /chat/sessions/:id/read clears unread; broadcasts
chat:session_read so other devices sync
- New GET /chat/pending-tasks aggregate for the FAB
- ChatFab: brand-color impulse animation while running, brand-dot
badge of unread session count
- ChatWindow auto-marks read when user is viewing the session
Header redesign
- Two independent dropdowns: agent (avatar + name + My/Others
grouping) at the input bottom-left; session (title + agent avatar)
in the header
- ⊕ new-chat button replaces the old + and history buttons
- Session dropdown lists all sessions across agents with avatars
- Empty state: 3 clickable starter prompts that send immediately
- Mention link renderer falls through to default span on null —
fixes @member/@agent/@all silently disappearing app-wide
- User messages render through Markdown
- Enter submits in chat input only (with IME guard + codeBlock skip);
bubble menu hidden in chat
Misc
- Partial index on agent_task_queue for fast pending-task lookup
- 2 new storage keys added to clearWorkspaceStorage
- useMarkChatSessionRead has onError rollback
- chat.* namespace logs across store, mutations, components, realtime

Remove the archive button, active/archived grouping, and related
imports from ChatSessionHistory. This also fixes the nested <button>
hydration error (GitHub #875) since the inner archive Button was the
only nested button inside the row's outer <button>.
- Add optimistic update + rollback to archive mutation
- Replace Trash2 with Archive icon (correct semantics)
- Add Tooltip on archive button, replace native title
- Show spinner during archive, toast on error
- Use cn() for className composition
- Align chat window offset to bottom-2 right-2 (match FAB)

- Document wsId/header coupling in chat queries (cache key vs API call)
- Extract finalizePending helper to reduce duplication across 4 WS handlers
- Store chat store handle in module-level variable for consistency with

Move chat queries, mutations, and store from apps/web/core/chat/ and
apps/web/features/chat/store.ts to packages/core/chat/. Refactor store
to use createChatStore({ storage }) factory pattern (mirrors auth store)
so it works in both web (localStorage) and desktop (Electron) without
direct browser API access. Register chat store in CoreProvider.initCore.
