Problem
-------
On desktop, creating a new tab triggered thousands of chat-store
rehydration logs per second (sustained for seconds). Same session,
same workspace — nothing actually changed. `pnpm test` was clean; the
bug only manifests at runtime with React 19 Activity + multi-tab.
Root cause
----------
Every tab's WorkspaceRouteLayout kept its own `syncedSlugRef` to decide
"did slug change since last sync". That model assumes one layout
instance equals one workspace context — true on web, false on desktop
where N tabs each mount their own layout. Activity remounts +
tab-router-sync stirring the tab store caused per-layout refs to drift
out of agreement with the module-level truth, so each ref independently
called `rehydrateAllWorkspaceStores()`. The existing microtask dedup
only coalesced same-tick calls; successive ticks each scheduled another
iteration through every registered rehydrate fn.
Fix
---
Move the "did slug actually change?" decision to where the truth lives:
inside `setCurrentWorkspace` itself. The singleton now:
- Returns immediately when the slug is already current (idempotent).
- Fires slug subscribers + persist rehydrate as internal side effects
when (and only when) the slug transitions.
Layouts are simplified to "feed the URL slug in"; they no longer
maintain a ref guard or call rehydrate explicitly. N tabs feeding the
same slug is naturally a no-op after the first — the model no longer
depends on "one layout instance" as an implicit invariant.
Also hardens the original render-time race that motivated the v2
refactor: both layouts now gate on `!listFetched || !workspace` so
`useWorkspaceId()` in descendants is guaranteed non-null.
Public API
----------
`rehydrateAllWorkspaceStores` removed from `@multica/core/platform`
exports — it's now purely an internal effect of `setCurrentWorkspace`.
The function itself is deleted; the rehydrate loop lives inline in
`setCurrentWorkspace`.
Tests
-----
Four new tests covering the new semantics: single rehydrate on mount,
same-slug noop across repeat calls, real workspace switch fires again,
logout → re-entry into same workspace fires again.

* Reapply "feat: workspace URL refactor + slug-first API identity (#1131)" (#1137)
This reverts commit 9b94914bc8.
* compat: legacy URL redirect + localStorage double-write for safe rollback
The first attempt at this refactor (#1131) was reverted because existing
users on old URLs (/issues, /projects, etc.) hit 404 immediately after
deploy, and rolling back left them with empty dashboards — the legacy
code reads localStorage["multica_workspace_id"] to attach a workspace
to API requests, but the new code had stopped writing that key.
Two compat layers added on top of the restored refactor:
1. proxy.ts now intercepts legacy route prefixes (/issues/*, /projects/*,
/agents/*, /inbox/*, /my-issues/*, /autopilots/*, /runtimes/*,
/skills/*, /settings/*). Logged-in users with a last_workspace_slug
cookie are 302'd to /{slug}/{rest}, preserving their deep link. Users
without the cookie bounce through / where the landing page picks a
workspace client-side. Unauthenticated users go to /login.
2. Both layouts now double-write the workspace id to the legacy
localStorage key on every workspace entry. New code ignores this key
— it exists solely so that if this PR ever gets reverted again, the
legacy build reading the key would still find the correct workspace
and avoid the empty-dashboard symptom users saw during the rollback.
Net effect: any direction of deploy ↔ rollback is now cache-compatible,
and any direction of old bookmark → new route resolves without 404.

* fix(platform): defer rehydrateAllWorkspaceStores to a microtask
Same React 19 render-phase restriction that forced setCurrentWorkspace
to defer its subscriber notifications. rehydrateAllWorkspaceStores
synchronously calls each persist store's rehydrate, which setState()s
the store, which schedules updates on any subscribed component. When
the workspace layout's render-phase ref guard invoked this, React
complained that SearchCommand (a store subscriber) couldn't be
re-rendered while WorkspaceLayout was still rendering.
Fix: queueMicrotask the rehydrate loop and add a pending-flag guard so
rapid workspace switches coalesce into one rehydrate on the final slug.
Persist stores tolerate one microtask of staleness — they hold UI
preferences, not correctness-critical state.

* feat: workspace URL refactor + slug-first API identity
Make the URL the single source of truth for workspace identity.
All workspace-scoped URLs now carry the workspace slug as the first
path segment (/{slug}/issues, /{slug}/projects, etc.), matching the
industry standard (Linear, Notion, Vercel, GitHub).
## Key architectural changes
**URL-driven workspace identity:**
- Web routes moved under app/[workspaceSlug]/(dashboard)/
- Desktop routes nested under /:workspaceSlug
- paths.ts builder centralises all URL construction
- reserved-slugs validation (backend + frontend + DB migration audit)
**Slug-first API contract:**
- Frontend sends X-Workspace-Slug header (from URL) instead of X-Workspace-ID (UUID)
- Backend middleware resolves slug → UUID via GetWorkspaceBySlug, falls back to
X-Workspace-ID for CLI/daemon backwards compatibility
- WebSocket auth accepts ?workspace_slug query param with SlugResolver callback
**State cleanup:**
- Deleted: useWorkspaceStore (Zustand mirror), switchWorkspace/hydrateWorkspace/
clearWorkspace, localStorage["multica_workspace_id"], api._workspaceId
- useCurrentWorkspace() derives from URL slug + React Query workspace list
- useWorkspaceId() is now a bridge hook (no Context, derives from useCurrentWorkspace)
- WorkspaceIdProvider removed from DashboardGuard
- Paired module vars (slug + UUID) in workspace-storage.ts for non-React consumers
**Layout simplified:**
- Render-phase ref guard sets workspace context synchronously (no async gate)
- DashboardGuard handles auth redirect, loading state, and workspace resolution
- Subscriber notifications deferred via queueMicrotask (React 19 compat)
- persist namespace uses slug (immutable) instead of UUID
## Issues resolved
MUL-43 (share links), MUL-509 (mobile workspace switch), MUL-723 (workspace in URL),
MUL-727 (create workspace flash), MUL-728 (delete workspace no-navigate),
MUL-820 (sidebar Join not switching)

* fix: resolve code review C3/C4/C5/C6 — desktop deadlock + hardcoded paths
C3: Desktop OnboardingGate was calling useCurrentWorkspace() outside
WorkspaceSlugProvider → always null → permanent onboarding deadlock.
Rewrite to use useQuery(workspaceListOptions()) which reads React Query
cache directly without slug context. Remove DashboardGuard from
DesktopShell (auth gating handled by AppContent, workspace routing by
WorkspaceRouteLayout per-tab).
C4: Landing page "Dashboard" links hardcoded /issues (no longer valid).
Changed to / — proxy handles redirect to /{lastSlug}/issues.
C5: autopilots-page.tsx had one hardcoded /autopilots/${id} link.
Changed to wsPaths.autopilotDetail(id).
C6: inbox-page.tsx hardcoded /inbox paths. Changed to wsPaths.inbox().

* fix(desktop): wrap shell in WorkspaceSlugProvider from module var
AppSidebar calls useWorkspacePaths() → useRequiredWorkspaceSlug() which
throws outside WorkspaceSlugProvider. In the desktop shell, the sidebar
renders at the shell level (outside any tab's WorkspaceRouteLayout).
Fix: DesktopShell reads the current slug via useSyncExternalStore on
the workspace-storage singleton. When slug is available, wraps the
entire shell in WorkspaceSlugProvider. When null (first mount before
any tab's WorkspaceRouteLayout sets it), shows a loading spinner.

* fix(desktop): migrate old tab paths + fix shell slug deadlock
Tab store rehydration: old-format paths like "/issues/abc" (missing
workspace slug prefix) are reset to "/" so IndexRedirect picks the
correct workspace. Detection: if the first segment is a known route
name (issues, projects, etc.) rather than a workspace slug, it's an
old-format path.
Desktop shell: TabContent must always render (not gated behind slug
check) so WorkspaceRouteLayout can mount and call setCurrentWorkspace.
Only sidebar and shell-level UI (chat, modals, search) gate on slug
being present.

Full-width Chinese punctuation (e.g. ，) was rendering at Latin-font
metrics, making it look half-width in the editor. Root cause: Geist is
Latin-only, and neither web (next/font) nor desktop (@fontsource) declared
any CJK fallback, so CJK chars inherited Geist's em-box width through
Chromium's per-character fallback.
- Web (apps/web/app/layout.tsx): Geist → Inter via next/font/google,
with explicit fallback array: system fonts → PingFang SC (macOS) →
Microsoft YaHei (Windows) → Noto Sans CJK SC (Linux) → sans-serif.
- Desktop: removed @fontsource/geist-sans, added @fontsource-variable/inter
(single variable-weight file replaces 4 static weights). Updated
--font-sans in globals.css to match web's fallback chain.
- Geist Mono kept for code blocks; mono chain has no CJK fallback by
design (CJK is non-aligned in mono grids, listing CJK fonts would
falsely signal alignment guarantees). Added Consolas to web mono for
Windows symmetry with desktop.
- Cross-reference sync comments in both layout.tsx and globals.css:
CJK tail must stay in sync; Inter primary differs by design (next/font
injects `__Inter_xxx` with adjustFontFallback metric override;
fontsource uses raw "Inter Variable").
Currently covers English + Simplified Chinese. When ja/ko i18n lands,
extend fallback tails with Hiragino Kaku Gothic ProN / Yu Gothic /
Apple SD Gothic Neo / Malgun Gothic.

* feat(autopilot): add scheduled/triggered automation for AI agents
Introduce the Autopilot feature — recurring automations that assign work
to AI agents on a schedule or manual trigger. Supports two execution
modes: create_issue (creates an issue for the agent to work on) and
run_only (directly enqueues an agent task without issue pollution).
Backend: migration (3 tables + 2 columns), sqlc queries, AutopilotService
with concurrency policies (skip/queue/replace), HTTP CRUD + trigger
endpoints, background cron scheduler (30s tick), event listeners for
issue→run and task→run status sync.
Frontend: types, API client methods, TanStack Query hooks with optimistic
mutations, realtime cache invalidation, list page with create dialog,
detail page with trigger management and run history, sidebar nav + routes
for both web and desktop apps.
* feat(autopilot): improve UX — trigger config, edit dialog, template gallery
- Replace raw cron input with friendly frequency tabs (Hourly/Daily/Weekdays/Weekly/Custom), time picker, and timezone dropdown defaulting to user's local timezone
- Fix Select components showing UUIDs instead of names (Base UI render function pattern)
- Add Edit button on detail page opening a unified edit dialog
- Remove project/concurrency/issue-title-template from create/edit (simplify for users)
- Add trigger configuration inline during autopilot creation
- Add template gallery on empty state (6 step-by-step workflow templates)
- Rename "Description" to "Prompt" throughout UI
- Inject autopilot run timestamp into issue description for agent date awareness
- Treat issue status "in_review" as run completion (fixes skip on next trigger)
- Make migration idempotent with IF NOT EXISTS clauses
The login page now encodes the ?next= param into the Google OAuth state
so the auth callback can redirect to the right destination (e.g.
/invite/{id}) after login, instead of always going to /issues.
The email CTA now deep-links to /invite/{id} instead of the generic app
URL. If the user isn't logged in, they're redirected to login with a
?next= param that brings them back to the invite page.
Changes:
- Backend: GET /api/invitations/{id} endpoint (enriched with workspace/inviter names)
- Backend: Email template now links to /invite/{invitationId}
- Frontend: Shared InvitePage component (packages/views/invite/)
- Frontend: Web route at (auth)/invite/[id], Desktop route at invite/:id
- Frontend: /invite/ excluded from navigation history persistence
* feat(onboarding): add full-screen onboarding wizard for new workspaces
Replace auto-provisioned workspace with an interactive 4-step onboarding
wizard: Create Workspace → Connect Runtime → Create Agent → Get Started.
- Remove server-side ensureUserWorkspace() so new users land in onboarding
- Add onboarding wizard in packages/views/onboarding/ (4 steps)
- Wire login/OAuth callbacks to redirect to /onboarding when no workspace
- Add DashboardGuard onboardingPath fallback for workspace-less users
- Sidebar "Create workspace" navigates to /onboarding instead of modal
- Remove CreateWorkspaceModal (replaced by wizard step 1)
- Auto-generate workspace slug from name (no user-facing URL field)
- Unified CLI install flow: install.sh + multica setup (auto-detects local)
- Create onboarding issues on completion with interactive "Say hello" task
* test(auth): update workspace tests to match onboarding flow
Login no longer auto-creates workspaces — new users start with zero
workspaces and create one through the onboarding wizard. Update both
integration and handler tests to assert 0 workspaces after verify-code.
Desktop Google login flow: click "Continue with Google" → opens default
browser to web login page with platform=desktop → Google OAuth completes
→ web callback redirects to multica://auth/callback?token=<jwt> →
Electron receives deep link, extracts token, completes login.
Changes:
- Register `multica://` protocol in Electron (main process + builder)
- Add single-instance lock with deep link forwarding (macOS + Win/Linux)
- Expose `desktopAPI.onAuthToken` and `openExternal` via preload IPC
- Add `loginWithToken(token)` to core auth store
- Pass `state=platform:desktop` through Google OAuth flow
- Web callback detects desktop state and redirects via deep link
- Desktop renderer listens for auth token and hydrates session
LoginPage now calls useQueryClient() after the workspace list migration.
All test renders need a QueryClientProvider; add a createWrapper() helper.

- staleTime: 0 on fetchQuery after leave/delete so fresh data is fetched
- setQueryData before switchWorkspace in createWorkspace so sidebar is
consistent on first render
- seed workspaceKeys.list() cache in login, Google callback, and
settings save so the first useQuery(workspaceListOptions()) hit is free
- remove dead onError from WorkspaceStoreOptions (used only by the
deleted refreshWorkspaces action)

Move chat queries, mutations, and store from apps/web/core/chat/ and
apps/web/features/chat/store.ts to packages/core/chat/. Refactor store

* feat(sidebar): redesign sidebar layout for better space usage and grouping
- Split header into two rows: workspace switcher (full width) + search bar with new issue button
- Regroup navigation: Personal (Inbox, My Issues) + Workspace with label (Issues, Projects, Agents, Runtimes, Skills)
- Move Settings to SidebarFooter (like Linear)
- Search now renders as a full-width input-style button with ⌘K hint
Closes MUL-441
* fix(sidebar): style ⌘K shortcut as bordered badge matching project conventions
Use bordered kbd badge (bg-muted, border, font-mono) consistent with
search-command.tsx pattern. Render ⌘ symbol slightly larger for readability.
* feat(sidebar): add user profile info to footer
Show user avatar, name and email at the bottom of the sidebar
with a dropdown menu for logout, similar to the Lumis reference design.
* refactor(sidebar): move Settings back to Workspace nav, footer shows only user info
Settings is a navigable page that belongs with other nav items.
Footer now cleanly separates identity (user profile) from navigation.
* refactor(sidebar): split Workspace into Workspace + Configure groups
Split 6-item Workspace group into two cleaner groups:
- Workspace: Issues, Projects, Agents (core collaboration)
- Configure: Runtimes, Skills, Settings (infrastructure/admin)
* fix(sidebar): align search bar with nav items
Remove extra px-2 from search container and change button px-2.5 to px-2
so the search icon aligns at the same left offset as nav item icons.
* refactor(sidebar): make search and new issue regular menu items
Replace bordered input-style search bar and icon button with
SidebarMenuButton components so they share the same visual weight,
padding, and hover behavior as all other nav items.
Add a visible search trigger button next to the create-issue button in
the sidebar header, improving search discoverability (previously only
accessible via ⌘K). Search dialog open state is shared via a Zustand
store so both the button and keyboard shortcut work.
Also restores turbo.json globalEnv config (FRONTEND_PORT, etc.) that was
accidentally dropped during the monorepo extraction, fixing worktree
port conflicts.

- globals.css: widen @source globs from *.tsx to *.{ts,tsx} so
Tailwind scans .ts config files — fixes bg-info being purged
(Done badge invisible in light mode)
- layout.tsx: hoist WorkspaceIdProvider above SidebarProvider so
AppSidebar (which now calls useWorkspaceId via useMyRuntimesNeedUpdate
from #533) doesn't throw on mount
* feat(runtime): proactive CLI update notifications with per-user filtering
- Add latestCliVersionOptions query (GitHub Releases API, 10-min TanStack cache)
- Add useMyRuntimesNeedUpdate / useUpdatableRuntimeIds hooks using owner_id
- Show red dot on sidebar Runtimes item when user's runtimes need updates
- Show update arrow icon alongside status dot in runtime list items

Implement the Master Agent chat feature allowing users to chat with agents
directly from a floating window, separate from the issue-based workflow.
Backend:
- New chat_session and chat_message tables (migration 033)
- Make issue_id nullable on agent_task_queue for chat tasks
- REST API: create/list/get/archive sessions, send/list messages
- EnqueueChatTask in TaskService with session_id persistence
- WS events: chat:message, chat:done
- Daemon: chat task type with separate prompt builder
- ClaimTaskByRuntime populates chat context (session, message, repos)
Frontend:
- ChatSession/ChatMessage types + API client methods
- core/chat: TanStack Query options, mutations with optimistic updates, WS updaters
- features/chat: Zustand store, ChatFab (floating button), ChatWindow with
real-time streaming via task:message events
- Mounted in dashboard layout (bottom-right corner)

* feat(search): implement full-text search for issues
Add pg_bigm-based full-text search across issue titles and descriptions,
with API endpoint, CLI subcommand, and web Cmd+K search dialog.
- Migration 032: pg_bigm extension + GIN indexes on title/description
- Server: GET /api/issues/search?q=... with pagination and total count
- CLI: `multica issue search <query>` with table/json output
- Web: Cmd+K command palette using cmdk, with debounced search

* fix(search): address review feedback on search implementation
1. Escape LIKE special characters (%, _, \) in handler to prevent
matching anomalies from user input.
2. Wire AbortController signal into searchIssues fetch so in-flight
requests are actually cancelled on new input.
3. Fix offset=0 falsy check — use !== undefined instead of truthiness.
4. Merge results + count into single query using COUNT(*) OVER()
window function, eliminating the duplicate DB round-trip.
5. Exclude done/cancelled issues by default; add include_closed
parameter to API, CLI (--include-closed), and web client.

* feat(search): add comment search with snippet extraction
Extend search to cover issue comments in addition to title/description.
Results are deduplicated at the issue level, with match_source and
matched_snippet fields indicating where and what matched.
- Migration 033: pg_bigm GIN index on comment.content
- SQL: EXISTS subquery for comment matching, correlated subquery for
snippet extraction, 3-tier ranking (title > description > comment)
- Server: SearchIssueResponse with match_source and matched_snippet
- Web: show comment icon + snippet below issue title when matched
- CLI: MATCH column shows source and truncated snippet

The root layout called `await cookies()` to read the locale, which
marked the entire app as dynamic. In Next.js 16, dynamic pages have
Router Cache staleTime=0, causing a fresh RSC server roundtrip on
every navigation — the root cause of ~400ms tab switching delays.
- Remove cookies() from root layout, making it static
- Add LocaleSync client component to read locale cookie on the client
- Add loading.tsx skeleton for dashboard routes as a loading fallback
* feat(issues): add sub-issue support
- Backend: Add ListChildIssues SQL query, add parent_issue_id to UpdateIssue,
add GET /api/issues/{id}/children endpoint
- Frontend: Display parent issue breadcrumb and link in issue detail sidebar,
show child issues list with status icons, add "Create sub-issue" action in
dropdown menu and sidebar, pass parent_issue_id through create issue modal
- Update test mocks for new API method
* fix(issues): add parent validation, cycle detection, and improve child refresh
- CreateIssue: validate parent issue exists in the same workspace
- UpdateIssue: validate parent exists, prevent self-referencing, detect
circular parent chains (up to 10 levels deep)
- Frontend: derive child issues from store when available instead of
refetching on every global issue count change
