* fix: preserve lastEventId in SSE path and add proxy heartbeat
- Extract event.id from SSE stream events in event-pipeline.ts so that
reconnects carry the correct Last-Event-ID header for gapless replay.
- Emit :heartbeat comment every 20s in the direct SSE proxy to keep
the UI heartbeat watchdog from aborting idle connections.
* fix: handle SSE metadata through SDK callback
* Guard SSE proxy heartbeats

* feat: make pinned folders expandable to browse subdirectories in project picker
Pinned folders in the Add Project dialog now show an expand/collapse
arrow. When expanded, subdirectories are lazily loaded and rendered as
a recursive tree, allowing users to browse into pinned parent folders
(e.g. a 'local-dev' folder) and pick any nested subfolder as a project.
* chore: trigger CI re-run
* fix: remove duplicate expand button in dropdown pinned tree variant
* fix: make pinned tree row tooltip conditional on pin state
* Fix pinned folder tree cleanup

* feat: improve agent and quick model picker behavior
* fix: keep the active model highlighted in the quick picker
* feat: streamline mobile model selection
Open the full mobile model picker directly and remove the intermediate controls drawer so mobile model changes follow the same core selection flow as desktop.
Add inline thinking-mode chips that show each model's remembered or default variant, apply model and variant together on tap, and fall back to a dedicated overflow panel for larger variant sets. Also keep favorites and recents searchable on mobile and fix clearing remembered default variants so the picker stays consistent across sessions.
* fix: polish desktop model picker interactions
Stabilize desktop model picker behavior by keeping keyboard and hover selection in sync, preventing hover-driven closes, and making the footer hints visually stable.
Also make quick-picker thinking mode changes apply consistently when switching plan/build or agent mode inside the picker, clamp left/right variant cycling at the ends, and keep thinking feedback visible even when the selected variant cannot move further.
* fix: condense mobile model picker rows
Tighten the mobile model picker to use a more compact, consistent row layout across favorites, recents, and provider sections while keeping context length and capability icons easy to scan.
Also preserve inline thinking-mode selection, improve metadata spacing, and keep the mobile controls readable without reintroducing the heavier drawer-based flow.
* fix: include all primary-like agents in picker cycling
Keep desktop Tab cycling and mobile tap cycling aligned with the rest of the selection UI by including agents marked as all or left unset, not just strict primary agents.
* fix: preserve remembered agent variants in picker flows
* Fix model picker variant restore
* Polish favorite model drag handle
* Fix Korean model picker locale

areRenderRelevantPartsEqual did not compare the tool part output field,
so when the AI updated a todo list (e.g., marking items completed) the
ToolPart memo comparator returned true and skipped re-render. The UI
stuck showing stale task status.
Fix: add output reference comparison for tool parts in
areRenderRelevantPartsEqual so streaming tool output updates trigger
re-renders correctly.

Files/directories/recentFiles render only on the 'files' tab; agents
only on 'agents'. Memoize visible slices and drop loading spinner when
the files tab is inactive.
Remove body position:fixed lock, visualViewport listener in MainLayout
(keyboard-inset heuristics, scroll-to-zero lock, focusin/focusout RAF),
[data-keyboard-avoid-active] translateY rule, and related CSS vars
(--oc-keyboard-inset, --oc-keyboard-avoid-offset, --oc-keyboard-home-indicator,
--oc-visual-viewport-offset-top). Strip data-keyboard-avoid* attrs and
keyboardAvoid props from Dialog/ScrollableOverlay and consumers. Drop
isKeyboardOpen from useUIStore.
With body unlocked and the layout plain flex-col (h-dvh), the browser
shrinks the viewport on keyboard open naturally — composer sits above
the keyboard, header stops lagging, input no longer jitters.
FilesView.nudgeEditorSelectionAboveKeyboard now derives the occluded
bottom locally from visualViewport + documentElement.clientHeight.
* feat: add 'Open files in preview mode' setting
- Add defaultFileViewerPreview setting to persist user preference for file viewer default mode
- Add checkbox in Settings → Sessions → Session Defaults to toggle the setting
- Files now open in preview mode by default when setting is enabled
- Respects per-file-type localStorage persistence for markdown/HTML/JSON files
- Setting persists across sessions via /api/config/settings endpoint
* fix: address PR review feedback
- FilesView: respect HTML localStorage preference in file-change effect,
falling back to global setting only when nothing stored
- DefaultsSettings: read defaultFileViewerPreview directly from config store
instead of redundant local state + separate fetch
- DefaultsSettings: extract duplicated toggle logic into
handleToggleFileViewerPreview callback
* fix: honor default preview setting for markdown files
Previously mdViewMode only read localStorage on mount (deps: []), so
when settingsDefaultFileViewerPreview was enabled and no MD_VIEWER_MODE_KEY
was stored, markdown files silently opened in edit mode — ignoring the
setting for the very file type users most want to preview.
Fold md init into the per-file-change effect, mirroring the html handling:
localStorage preference wins, falling back to the setting-derived default.
The saveMdViewMode callback stays untouched so user-initiated toggles
still persist.

* perf: drastically improve cold-start, bundle size, and streaming performance
Cold-start optimizations:
- main.tsx: Remove blocking await on prefs I/O — render immediately with
defaults, hydrate persisted settings asynchronously. Cuts 50-200ms from
time-to-first-paint.
- bootstrap.ts: Split directory bootstrap into 3 phases:
* Phase 1 (blocking): path, config, provider, session status — minimum
data needed to render UI. Mark status complete after this phase.
path.get and session.status must both succeed; they have no fallback.
* Phase 2 (deferred): agents, commands, mcp, lsp, vcs, questions,
permissions — fetched after first paint without blocking.
* Phase 3 (lazy): session messages — loaded without blocking init.
- App.tsx: Keep identical provider tree before/after init to prevent
full subtree remount when isInitialized flips. FireworksProvider and
VoiceProvider are lightweight shells; overlays deferred until init.
Bundle-size optimizations:
- App.tsx + MainLayout.tsx + VSCodeLayout.tsx: Code-split heavy views
(SettingsView, GitView, DiffView, TerminalView, FilesView, PlanView,
OnboardingScreen, SettingsWindow, MultiRunWindow) with React.lazy.
Views load on demand when user switches panels.
- vite.config.ts: Lower chunkSizeWarningLimit from 1200KB to 500KB.
Streaming render optimizations:
- streaming.ts: Throttle streaming store writes ~60Hz → ~1Hz. Busy-session
only scan (Set, O(1)).
- MessageList.tsx: Lower virtualization threshold 40 → 15.
- ChatMessage.tsx: React.memo with areRenderRelevantMessagesEqual.
- MarkdownRenderer.tsx: React.memo with explicit prop comparators.
* fix: address Greptile review feedback on bootstrap and provider tree
- bootstrap.ts: Tighten Phase 1 error guard. path.get and session.status
must both succeed; they have no global fallback.
- bootstrap.ts: Replace dead .catch() on Promise.allSettled() with .then()
that inspects individual results for errors.
- App.tsx: Keep identical provider tree before/after init to prevent full
subtree remount when isInitialized flips.
* fix: ensure settings watchers always start and harden bootstrap phase-1 guard
- main.tsx: Start appearance/model/typography watchers unconditionally
after initializing appearance preferences. Previously they only started
inside the secondary settings Promise.all().then(), so a transient I/O
failure would silently leave auto-save disabled for the entire session.
- VSCodeLayout.tsx: Move React.lazy SettingsView const after all imports
to satisfy ESLint import/first rule.
- bootstrap.ts: Replace fragile hardcoded array indices in Phase 1 guard
with destructuring so reordering the Promise.allSettled array won't
silently break the critical-failure check.

- Replace MarkdownRenderer.tsx with thin lazy wrapper using React.lazy
- All 11 existing imports work unchanged — no consumer code modified
- Full markdown stack loads on first render of markdown content
CodeMirror language lazy loading:
- languageByExtension.ts: remove static imports for 10+ less-common
language packages (@codemirror/lang-go, lang-rust, lang-sql, etc.)
- Keep only 6 most common languages static: javascript, json, css, html,
markdown, python, shell
- Less common languages return null from languageByExtension, causing
callers to fall back to loadLanguageByExtension which dynamically
loads from @codemirror/language-data
- Reduces initial bundle by ~200KB+ of language parsers

Add /review command with high-signal diff review instructions
Expose workspace review prompts in Magic Prompts settings
Show /review in command autocomplete with OpenChamber command metadata
Show commands with identical names from different sources
Add stable command IDs so selection no longer depends on name dedupe
Keep command insertion flow working across chat and prompt editors
Typing /summary (optionally with a topic hint) produces a structured
summary as a normal assistant message — without compacting or mutating
session history. Reuses the existing "Start new session from this answer"
button for hand-off.
Prompts are customizable in Settings → Magic Prompts under a new Session
group. Autocomplete shows an 'openchamber' badge to distinguish our
commands from OpenCode-built-in ones.
Recover stalled event streams without dropping the session
Wait briefly for reconnection before showing connection lost errors
Persist Electron server logs for easier disconnect debugging
* fix(pipeline): distinguish transport switch from real disconnect
WS_FALLBACK errors (e.g. ready timeout → SSE fallback) are transport
switches, not disconnections. No events are lost because lastEventId is
preserved across the switch.
Previously, every WS timeout triggered onDisconnect → onReconnect with a
full resyncDirectoryAfterReconnect, which:
- Missed idle parent sessions in candidate selection (root cause 1)
- Could overwrite in-flight SSE state with stale fetch data (root cause 4)
- Caused isConnected to flash false→true
Now: WS_FALLBACK fires onTransportSwitch (sets isConnected only).
Real disconnections (heartbeat timeout, network error) still fire the
full onDisconnect → onReconnect → resync cycle.
* fix(sync): relationship-aware reconnect with merge-not-replace
Two changes to resyncDirectoryAfterReconnect:
1. Candidate selection now also includes parent sessions of any child
sessions in the directory. Previously, if a child completed during
the disconnect gap (busy→idle), neither child nor parent was selected
because both appeared idle. The parent's task tool part would remain
permanently stale.
2. Parent resync merges parts instead of replacing. Previously, the
resync deleted parts for messages not in the fetch snapshot, which
could erase parts delivered by SSE events that arrived between the
fetch and the setState. Now only parts for messages in the snapshot
are overwritten; everything else is preserved.
* fix(sync): demand-load child session messages on access
Bootstrap only loads session metadata — messages are populated
exclusively by SSE events. When a user navigates to an old session
that spawned subagents, child session messages were never in the store.
Add useEnsureSessionMessages hook that detects this gap (session exists
in state.session but state.message[sessionID] is absent) and triggers a
background API fetch to load messages and parts.
ToolPart already calls useSessionMessageRecords(taskSessionId) which
returns empty when not loaded. Now it also calls useEnsureSessionMessages
to populate the store on first access.
* fix(sync): unmount-safe parent resync when child session goes idle
When a child session transitions to idle (completes), the sync layer
now schedules a targeted parts repair for the parent session's task
tool part. Previously this only happened when the ToolPart component
was mounted and had observed the child being active (taskChildSeenActive).
This covers:
- User navigated away while child was running
- App restarted with active subagent sessions
- SSE reconnect where child completed during disconnect
Uses the existing repairSessionParts mechanism with its 5s cooldown
to avoid redundant fetches.
* fix: type-check fixes for sync-layer parent resync
Fix TypeScript errors in Fix 5 implementation:
- Convert currentSessionId from null to undefined for resolveFallbackTaskSessionId
- Add default empty string for dir parameter in getScopedSdkClient
- Use explicit sessionID parameter for scopedClient.session.messages
All type-checks now pass.
* fix(sync): address PR review feedback on deduplication
- Use enqueuePartsRepair for session.idle parent resync instead of
direct repairSessionParts call. enqueuePartsRepair already has a 5s
cooldown to prevent redundant parallel API calls when multiple child
sessions go idle concurrently.
- Move useEnsureSessionMessages loading guard from component-scoped
React.useRef to a module-level Set keyed by directory:sessionID.
Prevents parallel fetches when multiple ToolPart instances mount
for the same child session.
* fix(sync): add missing semicolon on useEnsureSessionMessages call
Address Greptile P2 review comment on ToolPart.tsx:1931.
variant=default applied dark: primary-tinted bg/border that overrode the
status-info overrides (which only set light-mode). Add dark: variants so
the pill stays blue end-to-end.
Client previously built `${homeDirectory}/.config/openchamber/sessions-directories.json`
using client-side homeDirectory, which in some boot paths resolved to the
active workspace and wrote the file inside the project. Replace with
GET/POST /api/session-folders — server uses os.homedir() directly, so the
file always lands in ~/.config/openchamber/ regardless of client state.
Server now mirrors client-side Permission Auto-Accept via
POST /api/notifications/auto-accept and short-circuits permission.asked
dispatch (walking the session parent chain). Prior 500ms debounce raced
the client auto-response and leaked notifications.
Also hint under Summarize Last Message that templates must contain
{last_message} for the setting to take effect.
- ScrollShadow: 1px subpixel tolerance so bottom fade clears at scroll end
on Retina (fractional scrollTop was keeping data-bottom-scroll stuck)
- StatusRow: hide tasks indicator when no in-progress/pending todos remain
- Paginate /experimental/session via time.updated fallback so sidebar
loads past the 200-item first page when server omits x-next-cursor.
- VSCode extension persists all settings in shared
~/.config/openchamber/settings.json (not only opencodeBinary),
matching Desktop and Web. Canonical read from disk with globalState
fallback for eager migration of pre-existing users.
- Desktop settings sync: guard the contextBridge read-only
__OPENCHAMBER_HOME__ assignment that was silently throwing a TypeError
and skipping the whole applySettings chain — leaving server-synced
values (autoDeleteAfterDays, autoDeleteEnabled, sessionRetentionAction)
stuck at local defaults. Also wait for Zustand persist hydration before
applying server settings to avoid overwrite races.
