* feat: add project actions in header with reliable terminal run flow
- Add per-project Actions settings with icons, platform filters, and default action

- Improve terminal UX with stable selection, resize handling, and smarter URL auto-open for localhost ports
* feat: add project actions UI with refined header dropdown behavior
* feat: add parent-session back button in chat
* fix: make web and desktop dev modes reliable and conflict-free
- Separate desktop and web dev ports to avoid collisions

* feat: add mobile project actions button with terminal tabs and tighter tab UI
* revert: remove experimental mobile terminal selection UI
* feat: show Add action button in header when empty
* fix: make retry countdown human-readable in status row
* fix: prevent nav rail actions from firing through overlays
* feat(session-folders): drag-to-folder DnD, sort by activity, and UX improvements
- Add DraggableSessionRow wrapping each session row so the whole row is
draggable; stopPropagation prevents outer group-reorder DnD from firing
- Add DroppableFolderWrapper + SessionFolderDndScope (inner DndContext
scoped per group) with closestCenter collision detection
- DragOverlay matches exact width/height of dragged row so cursor stays
aligned
- Folder header highlights (ring + primary colour) when a session hovers
over it during drag
- + button on folder header opens a dropdown: 'New session' / 'New folder'
- + button on each folder row creates a session scoped to that folder
- Empty folders are no longer auto-deleted (removed .filter(sessionIds.length>0)
from addSessionToFolder / removeSessionFromFolder / cleanupSessions)
- Sessions inside a folder are sorted by most-recent activity (same
compareSessionsByPinnedAndTime logic used everywhere else)
- Sort comparator now takes sessionAttentionStates so lastUserMessageAt /
lastStatusChangeAt is used when newer than session.time.updated; all
sort call-sites and their useMemo/useCallback deps updated accordingly
- Remove foldersMap from cleanup effect deps to prevent cascade re-renders
when folders change; read current value via getState() instead
* fix(session-folders): new session is placed into the correct folder
sendMessage() was calling useSessionManagementStore.createSession()
directly, bypassing the targetFolderId logic in useSessionStore.createSession.
Fix: read targetFolderId from draft at the top of the draft branch in
sendMessage, then call addSessionToFolder immediately after the session
is created and before the draft is closed. Also propagate targetFolderId
through openNewSessionDraft options and NewSessionDraftState type.
* feat(session-folders): add sub-folder support (one level deep)
- SessionFolder gains optional parentId field for hierarchy
- createFolder accepts parentId to create sub-folders
- deleteFolder cascades to remove all child sub-folders
- SessionFolderItem renders sub-folders before sessions in body;
new sub-folder button (RiFolderAddLine) visible at depth 0 only
- renderOneFolderItem in SessionSidebar builds the tree recursively;
sub-folders are indented via depth prop (ml-3 on root's children)
- Persist/hydrate parentId correctly from localStorage
* feat(session): add delete confirm dialogs and improve subtitle UX
- Add confirmation dialogs before deleting sessions or folders
- Show relative time (e.g., '2h ago', '35min ago') for recent sessions
- Replace +/- diff numbers with file change count (e.g., '3 files changed')
- New folders use default name without forcing rename
- Cleaner, less cluttered session list UI
* fix(session-folders): skip folder cleanup while sessions are loading
Prevents race condition on reload where cleanupSessions() runs before
the server returns the full session list, causing folder-session
assignments to be incorrectly wiped from localStorage.
* feat(files): add 'Reveal in Finder' to file tree context menus
Add a new context menu action to reveal files and folders in the system
file manager (Finder on macOS, Explorer on Windows, xdg-open on Linux).
- Add POST /api/fs/reveal server endpoint with cross-platform support
- Add revealPath() to FilesAPI interface and web implementation
- Add 'Reveal in Finder' menu item to SidebarFilesTree and FilesView
- Files are highlighted in Finder (open -R), folders are opened directly

the banner is shown. Now it extracts conflict files directly from the
git status (files with 'U' status) and properly sets up the conflict
dialog state before opening it.
- Remove legacy worktree API usage and related state
- Add Manage Branches button in the Git header for quick access
- Introduce worktree status utilities to derive root branch hints
## What / Why
This PR finishes the desktop refactor: the Tauri app is now a thin shell that launches the web server as a sidecar and loads the UI from `http://127.0.0.1:<port>`. All real backend logic lives in `packages/web/server/index.js`; desktop Rust keeps only native integrations (menu/dialog/notifications/updater/deep-link + window chrome).
This unblocks:
- consistent behavior across web/desktop/vscode (single backend)
- simpler desktop maintenance (no duplicated Rust backend)
- host switching between Local + remote instances in desktop
- reliable cold-start behavior on slow machines (VSCode + desktop)
## Key changes
- Desktop sidecar runtime
- build pipeline to bundle web dist + `openchamber-server` sidecar (`packages/desktop/scripts/build-sidecar.mjs`)
- robust local port selection (prefer saved/default, fallback to random; persisted in `~/.config/openchamber/settings.json`)
- improved PATH handling so the sidecar can locate `opencode` CLI (incl `~/.opencode/bin`, overrides, common bins)
- disable native right-click context menu in production builds (dev keeps it)
- Desktop instance switcher (Tauri-only)
- header button + modal to add/edit/delete remote hosts, set default, probe status/ping, switch back to Local escape hatch
- auth gate includes host switcher so you can recover when a remote host is broken/auth-required
- host list stored desktop-locally (not tied to the currently selected remote server)
- Notifications
- decision logic moved server-side; desktop notifications emitted via sidecar stdout and shown natively by Tauri
- prevent double-notifications on desktop Local origin (UI ignores SSE notification when native path is active)
- restore macOS notification sound
- Updates
- Tauri updater used only when viewing Local instance in desktop shell (avoid “remote web update” triggering desktop restart)
- Settings persistence & UX polish
- persist model favorites/recents via `/api/config/settings` (works for web + desktop; not origin-dependent)
- persist per-project sidebar collapse state in `projects[].sidebarCollapsed` via `/api/config/settings` (with debounce on toggles)
- macOS header sizing/traffic-lights offsets fixed (marketing macOS major injected from desktop; MultiRun header aligned)
- VSCode cold-start: keep retrying provider/agent loads after connection to avoid empty UI on slow machines
- misc lint/type fixes + bun.lock sync
- Desktop bootstrap / resiliency
- show onboarding screen when OpenCode CLI is missing (desktop Local origin), with retry hook to restart OpenCode after install
## Testing notes
- Desktop (macOS): switch Local <-> remote, set default host, verify auth gate recovery, native notifications (with sound), updater gated to Local
- Web: favorites/recents + per-project collapsed state persist across reload/restart
- VSCode: slow startup no longer results in missing providers/agents/models

- Ensures icons are visible by default instead of only on hover/focus.
- Addresses user feedback about empty space at the bottom of chat bubbles.
* fix(ui): make chat message action icons always visible
- Removes opacity-0 and pointer-events-none classes from UserMessageBody action buttons container.
- Ensures icons are visible by default instead of only on hover/focus.
- Addresses user feedback about empty space at the bottom of chat bubbles.
* fix(ui): prevent diff comment input from closing on click (#3)
Replaced global `document.querySelector('[data-comment-ui]')` with a local `useRef` to detect clicks inside the comment input area. This fixes an issue where clicking the input in one diff viewer would close it if another diff viewer (found first by querySelector) existed in the DOM.
- Added `commentContainerRef` in `PierreDiffViewer.tsx`.

* Expose Opencode Core, Web, and Chamber via Cloudflare tunnels (#19)
This commit updates the GitHub Actions workflow and monitoring script to:
1. Install `wetty` to expose the core Opencode TTY over the web (interpreted from user request for "WiTTY").
2. Start `opencode web` (8080), `openchamber` (9090), and `wetty` (3000) concurrently.
