Bohdan Triapitsyn e892346c6b refactor: stabilize live chat sync materialization (#1132)
Canonicalize session message/part materialization across load, prefetch, reconnect, and recovery paths so OpenChamber restores session snapshots through one consistent merge flow.

Preserve live assistant streaming text when stale or delayed snapshots arrive, while still replacing optimistic user parts with confirmed server snapshots to avoid duplicated user messages.

Narrow recovery triggers to explicit incomplete snapshot signals instead of broad session-event fallbacks, reducing unnecessary session refetches during active streaming.

Keep turn windowing aligned with parented assistant replies and add regression coverage for materialization gaps, stale snapshot protection, optimistic user replacement, reconnect recovery, and turn grouping.

2b0e1ef42e fix(sync): preserve pending questions across session switch and directory eviction (closes #918) (#1103)
* fix(sync): preserve pending questions across session switch and directory eviction

Closes #918, completes the gap left by #909.

The 'agent question disappears after switching session / coming back
later' bug had two root causes that #909 only partially addressed:

1. Directory-eviction TTL (20 min) silently dropped child stores that
   held pending questions/permissions. The discard wasn't gated on
   in-flight blocking-request state, so any 'question.asked' event
   that arrived during the eviction-then-rehydrate window was routed
   to a non-existent store and silently lost.

2. PR #909 re-fetches listPendingQuestions/Permissions only on SSE
   reconnect. Switching sessions within the same socket — including
   navigating back to a directory whose child store was rebuilt after
   eviction — left the UI relying on store state that may have missed
   events that fired while a different session was active.

Three edits, in src/sync:

- eviction.ts / types.ts / child-store.ts: add hasPendingBlockingRequests
  to EvictPlan + DisposeCheck and never evict a directory whose store
  carries a non-empty state.question or state.permission record.
- sync-context.tsx: extract resyncBlockingRequestsForDirectory from the
  reconnect path and call it on currentSessionId changes (debounced
  250ms), reusing PR #909's signature-based merge so concurrent SSE
  updates aren't clobbered.
- __tests__/eviction.test.ts, __tests__/session-switch-resync.test.ts:
  new unit coverage for the eviction guard and resync semantics
  (deduped fetch per switch, in-flight SSE preservation, stale entry
  cleanup, unknown-session filtering).

* fix(sync): refresh store before blocking request resync

pasta-paulandBohdan Triapitsyn 1991736ebf fix(server): prevent streaming hang during long agent sessions (#1088)
* fix(server): increase WS buffer/replay limits and add backpressure warning

During long-running agent sessions (e.g. ultrawork loops with many tool
calls), the browser WebSocket client can briefly fall behind the server.
When the outbound buffer exceeds the limit, the server force-disconnects
with close code 1013, and the small replay buffer (512 events) is
insufficient to recover all missed events — leaving the UI permanently
stalled.

Changes:
- Raise MESSAGE_STREAM_WS_MAX_BUFFERED_BYTES from 4 MB to 16 MB to
  tolerate larger bursts without disconnecting
- Add MESSAGE_STREAM_WS_BACKPRESSURE_WARN_BYTES (12 MB) threshold that
  sends a one-shot "backpressure" frame to the client before the hard
  disconnect, giving it a chance to shed low-priority updates
- Raise MESSAGE_STREAM_GLOBAL_REPLAY_LIMIT from 512 to 2048 so more
  events survive brief reconnection gaps
- Add tests for the backpressure warning behavior (emit, dedup, reset)

* fix(ui): batch event flushes under backpressure

jwcrystalandBohdan Triapitsyn 03c9065c90 fix: preserve per-session scroll position on session switch (#1083)
* fix: restore scroll position when switching chat sessions

When switching between chat sessions, scroll position now restores to
where the user left off instead of always jumping to the bottom.

- Save pixel-level scrollPosition (scrollTop/scrollHeight/clientHeight)
  in viewport store on every scroll event
- Add restoreSavedScrollPosition to timeline controller for ratio-based
  restoration (handles content size changes between visits)
- Suppress intermediate scroll events during session transition with an
  explicit flag, cleared deterministically after restore completes
- Cancel in-flight animations/follow-loops on session switch
- Preserve scrollPosition when session-ui-store rebuilds SessionMemoryState

* fix: keep streaming sessions pinned on restore

bd9a91335c feat(preview): embedded dev-server preview pane + dev shutdown controls (#1062)
* feat: embedded preview proxy for local dev servers

Add a same-origin server proxy under /api/preview/proxy/:id and
matching UI surfaces so local dev servers (Vite, Next, etc.) can be
embedded inside OpenChamber.

Server (packages/web/server):
- New lib/preview/proxy-runtime.js: cookie-gated HTTP+WebSocket proxy
  to loopback hosts only, with TTL'd targets and SSRF allowlist.
- index.js wires the runtime alongside terminal/event-stream.

UI (packages/ui):
- ContextPanel preview tab with iframe, reload, and open-in-browser.
- Inline html code-block preview in MarkdownRenderer.
- Terminal auto-detects loopback URLs and offers to open them.
- i18n keys across en, es, pt-BR, uk, zh-CN.

* perf(preview): cache proxy targets across PreviewPane remounts

Module-scoped Map keyed by upstream URL so tab switches and component
remounts within the same page session reuse the existing proxy
registration instead of POSTing a fresh target each time.

In-memory only by design: the server holds the target map in memory
and the auth cookie is HttpOnly + scoped to the proxy id, so a stale
persisted entry would 404 after a server restart. Entries are evicted
on registration error and on a 30s safety margin before TTL expiry.

* feat(preview): surface dev-server-down state with retry overlay

Iframes don't expose HTTP status to the parent, so when the proxy
returns a 502 (upstream dev server is offline) the iframe just renders
the raw JSON error body. Probe the proxy URL out-of-band with HEAD
(falling back to GET on 404/405) and replace the iframe with a
friendly 'Dev server is not responding' overlay + retry button when
the upstream is unreachable.

Re-probes on reload, on URL change, and on proxy re-registration.

* feat(preview): strip frame-busting response headers

Many dev servers (Next.js, others) send X-Frame-Options: SAMEORIGIN
and/or a CSP with frame-ancestors that block embedding inside the
OpenChamber iframe. The proxy is same-origin and already
authenticated per-target, so embedding is otherwise safe.

- Drop X-Frame-Options outright on proxied responses.
- Surgically remove only the frame-ancestors directive from
  Content-Security-Policy and Content-Security-Policy-Report-Only,
  preserving every other directive. Drops the header entirely if no
  directives remain.
- Verified end-to-end: upstream sending both headers comes through
  with X-Frame-Options removed, CSP retaining default-src/script-src
  but no frame-ancestors, and unrelated headers untouched.

* docs(preview): design for remote-host relay agent

Design-only doc for the next phase of the embedded preview feature:
when OpenChamber runs remotely (cloud/shared/tunnel) and the user's
dev server runs on their local machine. Covers architecture (local
agent + outbound control WebSocket + server dispatch), pairing flow,
wire protocol, security model, failure modes, open questions, and
implementation milestones. No code changes.

* feat(preview): auto-open preview pane for loopback URLs in chat

Detect http(s) loopback URLs in incoming assistant messages and open the
preview pane automatically, deduped per (session, url) pair so re-renders
or repeated mentions do not steal focus. Add an inline Preview button
next to loopback links in chat markdown as a manual fallback when the
auto-open was dismissed or the URL appeared in an older message.

- url.ts: isLoopbackHttpUrl / extractLoopbackUrls helpers
- ChatContainer: module-level dedupe Set + effect on active session tail
- MarkdownRendererImpl: optional onPreviewLoopback in main renderer only
  (SimpleMarkdownRenderer for tool diffs is intentionally untouched)
- Reuses existing terminalView.preview.open i18n keys

* feat: preview enhancements, dev shutdown, and reliability fixes

Add preview start/stop UI in ContextPanel/Header, improve URL detection (Python HTTP server logs, trailing punctuation, IPv6 loopback), fix proxy path filtering to avoid disrupting non-preview WebSockets. Add dev-only /api/system/dev-shutdown endpoint and Header button to terminate local dev processes and orphaned preview servers. Improve terminal cleanup with process group killing, event pipeline reconnect backoff. Update file read APIs with optional flag and cache control. Add /api/system/free-port endpoint, detectDevServer.ts utility, and preview/shutdown i18n strings for 5 languages.

* fix: harden preview support

* fix: keep terminal toolbar interactive

* fix: keep expanded terminal below header

* fix: keep preview iframe under proxy path

* fix: respect project action preview urls

* fix: rewrite preview asset urls

* feat: capture preview console logs

* feat: annotate preview elements

* feat: attach preview annotation screenshots

* fix: improve proxied preview hmr

* feat: refine preview action UX

* fix: address preview review feedback

* fix: show auto-discover preview wait state

Dave OteroandBohdan Triapitsyn b62faadd15 Improve and unify the model picker across desktop and mobile (#1037)
* 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

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:

  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.

jwcrystal 17dd526731 fix: eliminate parent-child session desync across reconnect and navigation (#985)
* 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.

Bohdan Triapitsyn 5ec7f46105 fix: surface disconnect reason, switch health probe to /global/health (#978)
- event-pipeline: onDisconnect now carries a reason tag (ws_closed:code=N, ws_error_frame, ws_closed_before_ready, sse_error)
- useConfigStore: store lastDisconnectReason, clear on reconnect
- send guards: embed reason in Connection lost toast so we can tell which path tripped
- lifecycle: isOpenCodeProcessHealthy hits /global/health (healthy flag) with 5s timeout instead of /session with 2s, avoids false restarts under stream load

jwcrystalandBohdan Triapitsyn d4a4f43a83 feat: show file change summary bar (#950)
* feat: add FileChangeSummary component for multi-file diff preview in ToolPart

Provides an aggregated diff card for apply_patch and multi-edit tools,
showing per-file stats with click-to-expand diff view.

* feat: add PendingChangesBar above chat input with collapse/expand and file opening

- Collapsed/expanded toggle with aggregate +N -N stats (green/red)
- Relative path display, chat-column alignment with ChatInput
- Click file to open in diff viewer (web/desktop) or editor (VS Code)
- Support edit/multiedit/apply_patch/write tool metadata extraction
- Add PendingChangesBar to main chat view (ChatContainer)

* feat: dual-mode ChangedFilesBar — Git diff state vs latest AI turn

Git mode: reads git status from useGitStore (status.files + diffStats),
auto-clears on commit/restore. Shows 'N files changed in workspace'.

Non-Git mode: latest assistant turn only (no accumulation), clears on new
user message or manual dismiss. Shows 'AI updated N files in the last reply'.

Both modes: dismiss button with signature-based tracking.
Add pendingChangesBarDismissed state to session-ui-store, cleared on sendMessage.

* fix: address code review issues in ChangedFilesBar

- Gate non-git mode on streaming state to prevent flicker during AI turns
- Return null when isGitRepo is unknown (loading state)
- Add group/row class for reject button visibility in FileChangeSummary
- Use per-session Map for dismiss tracking to prevent cross-session leaks
- Include additions/deletions in dismiss signature for re-edit detection
- Extract shared parsePatchStats/parseCount to fileChangeHelpers

* chore: revert local .opencode/package-lock.json changes from PR

* fix: per-part fallback guard and git-only reject button

- Fix extractChangedFiles to use per-part files.length snapshot instead
  of global guard, preventing file entries from being skipped when
  earlier parts already contributed files
- Hide reject button in FileChangeSummary when not in a git repo,
  preventing silent revert failures

* refactor: remove FileChangeSummary — dead code redundant with ToolPart

FileChangeSummary duplicated diff rendering that ToolPart already
provides (PatchDiff, per-file stats, DiffViewToggle). The only unique
feature was a git revert button, which conflicts with the design
principle of not having accept/reject on file change previews.

Moved parsePatchStats/parseCount back into PendingChangesBar (sole
consumer) and deleted the shared helper module.

* chore: remove stray Tester.txt

* fix: deduplicate Fallback 4 'Diff' placeholder via seen set

* chore: update non-Git mode copy to neutral 'changed in the last reply'

* fix(chat): unify changes row with tasks

Bohdan Triapitsyn 34a8cb3f3b fix: don't silently swallow bootstrap SDK errors
sdk.path.get() / sdk.project.list() / sdk.app.agents() etc. return
{ data, error, response } without throwing on non-2xx. The x.data! /
x.data ?? [] pattern turned HTTP 5xx warmup responses into empty state,
and retry() never saw an error to retry.

Wrap everything through unwrap(): preserve the HTTP status on the
thrown Error so retry()'s transient detection (5xx) fires. Fixes the
class of bugs where a slow opencode sidecar leaves agents/commands/
sessions looking empty after startup.

Bohdan Triapitsyn f1b84e3291 fix: always signal connected state on first successful connect
markConnected skipped onReconnect when hasConnected was false and there
was no prior disconnect. Consumer state (isConnected) starts at false and
stayed false — the send button threw "Connection lost" until the HTTP
health check in initializeApp happened to race a setState through.

Now onReconnect fires on every successful connect; hasConnected is no
longer needed and gets removed.

Bohdan Triapitsyn 895edaf557 fix: preserve sessions when bootstrap races with event stream
Two fixes for intermittent "sessions missing at app launch":

- loadSessions: if session.list comes back empty but the store already
  has sessions populated via WS events, don't clobber. OpenCode can
  answer HTTP with [] while the WS snapshot is still arriving.
- loadSessions: wrap SDK errors preserving HTTP status so retry()'s
  transient detection (5xx) actually fires. String(errorObject) was
  erasing the status and retry gave up after one attempt.
- retry: broaden transient 5xx window from just 502/503 to any 5xx.
  OpenCode can return 500/504 while warming up (session store reading
  from disk), and those deserve the same retry treatment.
- Log bootstrap empty-session retries for future diagnosis.

Bohdan Triapitsyn c2eeadd9a3 fix: unstick isConnected when first connect follows a disconnect
markConnected skipped onReconnect on the very first successful connect
(hasConnected=false branch), but an earlier failed attempt could have
already fired onDisconnect -> isConnected=false. Consumer state stayed
stuck at false forever. Fire onReconnect in that case too.

Repro: launch app while opencode sidecar is still warming up so the
first WS attempt fails. Second attempt succeeds but isConnected stays
false; user sees "Connection lost" toast on every send.

Bohdan Triapitsyn a8a336b0a0 perf: halve stream flush cadence from 60hz to 30hz
FLUSH_FRAME_MS 16 -> 33. Delta events keep coalescing, just into larger
windows. AssistantTextPart already throttles text at 100ms, so the extra
granularity produced no visible benefit — just extra store.setState calls
and subscriber notifications per second.

Bohdan Triapitsyn 4506c18f53 UI refresh: Base UI migration + flat tinted button language + mobile polish (#960)
* deps: bump @opencode-ai/sdk to 1.4.6 and add @base-ui/react

* build: align vite configs with Base UI and packages update

* feat(ui): migrate primitives to Base UI

Replace Radix-based wrappers (button, checkbox, collapsible, command,
dialog, dropdown-menu, input, radio, scroll-area, select, separator,
sonner, switch, textarea, toggle, tooltip) with @base-ui/react
equivalents and a refreshed visual language: flexoki theme tokens,
typography utilities, and a redesigned CommandPalette. Add new
fancy-button variant set and a local slot helper for asChild composition.

* refactor(ui consumers): adopt Base UI primitives across the app

Update chat, layout, git views, settings, multirun, session and agent
management screens to use the new Base UI-backed primitives (anchor
width token rename, dropdown/select/dialog usage adjustments, new
component APIs).

* fix(ScrollableOverlay): forward `disabled` to inner element

Add `disabled` to the type so it propagates via rest spread to the
underlying element (e.g. textarea in simple mode). Resolves a type
error reported after the main merge.

* refactor(dropdown consumers): migrate preventDefault sites to closeOnClick

Base UI's Menu.Item does not check `event.defaultPrevented` before
closing the menu, so the Radix-era `onSelect={(e) => e.preventDefault()}`
pattern no longer keeps the menu open. Replace those sites with the
Base UI `closeOnClick={false}` prop (VSCodeLayout rate-limit info
rows; AgentGroupDetail worktree actions).

* docs(AGENTS): note Base UI as primary source for UI primitives

* fix(ContextPanel): center expand/close buttons in tab header

Header (h-8) had the action row pinned with items-end + pb-1.5, which
placed the h-7 buttons ~2px above the header top and made them look
cropped. Switch to items-center so they sit on the same baseline as
the tabs.

* style(tabs): drop transitions on default variant, soften active pill

Default (underline) variant now switches instantly — no transform/width
transition on the underline indicator, no color transition on tab
buttons. Active pill bg is color-mixed down to 55% of
--interactive-selection so light-theme selection doesn't scream.

* style(button): pill-style elevation and introduce chip variant

Solid variants (default/destructive/neutral/primary/basic) now use the
active-pill shadow stack — hairline navy outer ring + stacked tight/soft
drops — instead of the pure-black inset/border approach. Outline
variant (and FancyButton basic) gets the same elevation without the
white top highlight (no fill to catch light).

Add a new chip variant: flat `border border-border/60` button without
elevation, intended for one-of-N toggle groups where a raised
button would read as the wrong affordance.

* style(header): apply pill-style shadow to OpenIn and Project Actions

Both split-button wrappers previously used a 1px CSS border for
definition. Replace that with the pill elevation stack so the header
buttons match the new Button variants and feel less hard-edged.

* refactor(toggles): migrate one-of-N segmented groups to chip variant

Color Mode, When-sessions-expire, voice/STT providers, auth method,
agent mode, MCP transport, tunnel type and terminal Ctrl/Cmd modifier
toggles all read as flat chip selectors rather than raised buttons.
Switch them from variant="outline" to the new chip variant so the
raised pill-style elevation doesn't fight the selected-state tint.

* fix(elevation): theme-adaptive pill-style shadow for dark mode

The navy (rgba(14,18,27,*)) outer ring was invisible on dark surfaces,
erasing the button/pill edge. Add dark: variants that use a subtle
white outer ring (rgba(255,255,255,0.10)) and darker drop shadows
(rgba(0,0,0,0.30/0.20)) so the elevation reads on both themes.

Applies to Button solid/outline variants, FancyButton equivalents,
the OpenIn and Project Actions header split-buttons, and the active
pill indicator in SortableTabsStrip.

* style(button): flat tinted variants with squircle corner-shape

Replace elevated pill-shadow design with a flat tinted language: pale tinted
fill + hairline tinted border + saturated tinted text for default/destructive.
Add CSS corner-shape: squircle with @supports gate so Chrome 136+ gets the
softened superellipse corners at 50px, Safari falls back to a slightly larger
round radius.

* style(tabs): replace active pill shadow with tinted border

* style(header): flat border and squircle corners for OpenIn / Actions

Drop pill-style shadow stacks in favor of a plain hairline border and apply
the same squircle corner-shape treatment as Button so header controls match
the new visual language.

* style(checkbox): drop filled background for tinted checkmark

Checked / indeterminate states now keep the transparent box, show a
primary-base check/minus glyph, and use a softened primary-tinted inset
border (50% mix) so the control reads as selected without a solid swatch.

* style(layout): widen sidebar-to-chat corner radius to 10px

* style(button): retune tinted variants and unify outline fill

- Bump primary fill toward noticeable but still soft (light 10/16/22,
  dark 16/22/30) and weaken both primary and destructive borders
  (12% light / 20% dark) so the tone reads without shouting.
- Further calm destructive across fill and border so revert-style
  actions match the muted reference.
- Align the outline variant fill with --surface-elevated so git-view
  generate/commit buttons share the header action button surface.

* style(tabs): align pill variant with new button language

Active pill now uses --surface-elevated fill and border-border/60 to
match the outline button. Track and tab/pill geometry adopt the same
squircle treatment as Button: 9-10px fallback with 50px radius under
@supports(corner-shape:squircle). Also tighten track padding (inline
2px, block 2px) and grow active tab height so the indicator fills
the track instead of floating inside it.

* refactor(theme): hardcode radius scale, drop per-theme override

Radius values are now fixed in the design system (flexoki-dark's scale
becomes the app default). Themes can no longer override --radius-* — the
config.radius block is removed from every theme JSON, dropped from the
Theme type, and no longer emitted by the CSS generator.

* chore(ui): lint/type cleanup across Base UI wrappers

* style(tabs): dial pill track background down to near-invisible

* refactor(chip): aria-pressed drives the selected tinted state

The chip variant now carries the tinted primary palette (same as the
default filled button) under aria-pressed, so consumers toggle selection
via a single aria attribute instead of repeating the border/text/bg
override classes. All existing chip consumers migrate to aria-pressed
and drop their hand-rolled selected className.

* chore(defaults): humanize variant label in thinking selector

* fix(diff): render all lines in single-file mode

Single-file mode wrapped PierreDiffViewer in its own layout=fill which
creates a nested virtual-root; combined with the outer CSS containment
on the wrapper, Pierre's virtualizer measured a clamped viewport and
stopped rendering lines past ~150. Mirror the stacked-mode approach:
hoist a ScrollableOverlay as the sole virtual root/content and render
PierreDiffViewer inline, so the shared virtualizer sees the real scroll
viewport and paints every line.

Also drops an unused cn import in SessionRetentionSettings.

* feat(files): collapse floating editor controls behind icon button

The floating file editor toolbar now starts as a single pill icon button
and expands into the full control row on hover or click. Clicking outside
or moving the pointer away collapses it back, keeping the editor surface
unobstructed while the file is being read/edited. Fullscreen overlay
keeps its always-visible toolbar.

* fix(chat): align mobile session status bar radius with chat input

* fix(mobile): keep radio/checkbox/switch at their native size

Mobile CSS forced min 36x36px on every <button>, which swallowed our
Radio and Checkbox primitives (also buttons with role=radio/checkbox)
and ballooned them on touch devices. Exclude role=radio/checkbox/switch
from the touch-target rule and pin the Radio/Checkbox box size with
arbitrary px so padding-scale overrides cannot stretch them either.

* chore(mobile): drop unused cornerRadius prop plumbing

The status bar now hardcodes var(--radius-lg) on both views, so the
cornerRadius prop and the useUIStore selector that sourced it in
ChatInput are dead weight.

Bohdan Triapitsyn f04d732e15 fix(chat): resolve parent project for worktree-session messages
Save-as-plan and Add-to-notes actions were disabled on messages whose session
ran in a worktree, because session.directory alone does not reflect the
worktree attachment — the authoritative cwd lives in session-worktree-store.

Use useEffectiveDirectory (attachment cwd > worktree metadata > session.directory)
and resolve the parent project via the worktree map the sidebar already builds,
extracted into lib/projectResolution so session-ui-store and chat actions share
one resolver. No extra git calls.

Bohdan Triapitsyn 2766327a68 fix: tighten disconnect recovery guards 2026-04-17 19:00:44 +03:00
jwcrystal f5535dcaf1 fix: recover from sleep/wake disconnection with connection state tracking and immediate health check (#940)
When the computer sleeps and wakes, the SSE/WS event stream drops
silently. Messages appeared sent (optimistic insert) but never reached
the OpenCode server, and the user had no indication the system was
disconnected.

Three fixes:

1. Connection state tracking: add onDisconnect callback to the event
   pipeline. Stream failures set isConnected=false in useConfigStore;
   successful reconnect sets isConnected=true.

2. Send guard: optimisticSend, respondToPermission, and
   respondToQuestion now check isConnected before making API calls,
   throwing a clear error that surfaces as a toast to the user.
   The /compact command also checks connection with error feedback.

3. Faster server recovery: add triggerHealthCheck() to the server
   lifecycle and wire it into the WS event stream runtime. When the
   upstream OpenCode connection fails, the server immediately checks
   health and restarts if needed, instead of waiting up to 15s for
   the periodic health check.

Bohdan Triapitsyn 5bc52a15ad fix: remove risky worktree recovery on session switch 2026-04-16 23:10:31 +03:00
jwcrystalandBohdan Triapitsyn fccf4bad32 feat: session worktree isolation (#913)
* feat: add session-worktree contract types and canonicalizeWorktreeState API

- Add SessionWorktreeAttachment type and worktree metadata fields (worktreeRoot,
  worktreeStatus, headState, worktreeSource) to session/worktree types
- Add GitAPI.validateWorktreeDirectory() and canonicalizeWorktreeState() methods
  with full HTTP delegation chain (gitApiHttp → routes.js → service.js)
- Add canonicalizeWorktreeState() implementation that resolves worktreeRoot,
  headState (branch/detached/unborn), attentionReason (merge/rebase/etc), and
  worktreeStatus (ready/missing/invalid/not-a-repo) for a given directory
- Add validateWorktreeDirectory() to check whether a cwd is inside a worktreeRoot
- Add session-worktree-contract.ts: pure functions for resolving session worktree
  state, formatting badges, and building repair actions
- Add session-worktree-store.ts: authoritative Zustand store for session-to-worktree
  attachments, replacing session-ui-store as the source of truth for worktree binding
- Add unit tests for contract functions and store operations

* feat: canonicalize worktree metadata producers

- worktreeManager.listProjectWorktrees: derive headState (branch/detached/unborn)
  from worktree list entry instead of relying on external state, and populate
  all Phase 1 canonical fields (worktreeRoot, worktreeStatus, worktreeSource)
  for each discovered worktree entry
- worktreeManager.createWorktree: include all Phase 1 canonical fields
  (worktreeRoot, worktreeStatus, headState, worktreeSource) in returned metadata
- useDetectedWorktreeRoot: populate fallback canonical fields so that
  sessions without store-based metadata still have worktreeRoot/worktreeStatus/
  headState/worktreeSource when resolved through the fallback path

* feat: route sessions through authoritative worktree attachments

- session-ui-store: import session-worktree-store as the authoritative source
  for session↔worktree attachment state
- setWorktreeMetadata: mirror all writes to session-worktree-store so that
  session-worktree-store.attachments is always the authoritative record;
  local worktreeMetadata map is kept for backward-compatible reads
- Add session-ui-store.test.js with unit tests covering: valid cwd routing,
  degraded fallback, created-for-session attachments, legacy upgrade recovery,
  missing/not-a-repo status handling

* feat: clarify session worktree targets

- session-worktree-contract: extend buildSessionTargetOptions to accept
  pendingBootstrapDirectory and mark pending worktrees with pending=true;
  extend SessionTargetOption to include optional pending flag
- ChatInput: replace manual worktree branch options construction with
  buildSessionTargetOptions; add  prefix for pending bootstrap worktrees
- Add test for pending bootstrap worktree distinction

* feat: show worktree-backed session state

- Header: read worktree attachment from authoritative session-worktree-store
  and render needs-attention/degraded/missing badge with alert icon next to
  current session info when session has degraded/missing/invalid state
- GitView: show 'Worktree features are unavailable' message when session has
  missing worktree status and open-without-worktree-features repair action

* feat: enforce safe mutations for attached worktrees

- session-worktree-contract: add getMutationBlockingReasons helper that returns
  blocking reasons (missing/invalid/attention state) for high-risk mutations
- GitView: gate handleCheckoutBranch, handleCreateBranch, and handleRenameBranch
  with getMutationBlockingReasons; block with explicit toast message when
  worktree is missing, invalid, or has an in-progress git operation
- session-worktree-contract.test: add 7 tests covering mutation blocking for
  missing/invalid/attention states (merge/rebase/cherry-pick)

* feat: implement session worktree isolation

This adds a shared session↔worktree contract that makes session switching
worktree-backed. Sessions attached to different worktrees keep stable branch
context without shared-directory auto-checkout.

Commits:
- feat: add session-worktree contract types and canonicalizeWorktreeState API
- feat: canonicalize worktree metadata producers
- feat: route sessions through authoritative worktree attachments
- feat: clarify session worktree targets
- feat: show worktree-backed session state
- feat: enforce safe mutations for attached worktrees

* feat: make authoritative attachment first-priority source for session directory resolution

Phase A: resolveSessionDirectory, getDirectoryForSession, hooks read
authoritative attachment before falling back to worktreeMetadata.

Phase B: createSession canonicalizes and writes attachment on creation;
setCurrentSession recovers legacy/missing attachments via async
canonicalization.

* feat: make authoritative attachment the primary branch source in Header/GitView

Phase C: Header branch label and GitView project root now read from
authoritative SessionWorktreeAttachment first, falling back to live git
and legacy sources only when attachment is absent, degraded, or legacy.

Adds getAttachmentBranchLabel() helper with 7 tests.

* feat: add runtime parity for validateWorktreeDirectory and canonicalizeWorktreeState

Phase D: Web runtime API, VS Code bridge, and VS Code gitService now
expose validateWorktreeDirectory and canonicalizeWorktreeState, matching
the server-side implementations. All three runtimes (web, desktop, VS Code)
can now delegate worktree canonicalization without HTTP fallback.

* feat: add dirty-tree blocking to mutation safety gates

getMutationBlockingReasons now accepts an optional gitStatus param
and blocks branch mutations when the tree has uncommitted changes.
GitView passes live status to all three blocking call sites.
5 new tests covering dirty, clean, null, combined, and no-file-count cases.

* refactor: revert branch label to live-git-first, remove getAttachmentBranchLabel

Live git is the correct source for branch labels in all scenarios:
dedicated worktree sessions have identical live/attachment branches,
and shared-directory sessions must show the real current branch.

Attachment remains authoritative for worktreeRoot, cwd, degraded/
missing/repair status, and mutation blocking.

* chore: remove session worktree isolation plan doc

* refactor: simplify session worktree isolation implementation

jwcrystalandBohdan Triapitsyn ea5c19e934 fix(sync): deduplicate overlapping delta after coalesced part.updated (#916)
* fix: hide archived section and empty folders when no sessions remain

- Only push archived group in useSessionGrouping when there are archived
  sessions, preventing an empty archived section from rendering
- Hide empty folders in archived bucket via shouldKeepFolder check in
  SessionGroupSection (folders with no sessions and no content in
  children are filtered out)
- Always filter folders through shouldKeepFolder, not just during search

* perf: memoize archived folder filtering

* fix(sync): deduplicate overlapping delta after coalesced part.updated

When message.part.updated coalesces in the event pipeline and a
message.part.delta for the same part arrives in the same flush window,
the reducer appends the delta verbatim to the already-complete field
value, producing duplicated text in tool output and assistant messages.

Add targeted overlap reconciliation: only when a part.updated replaces
an existing part with overlapping string content, mark the next delta
for that field as dedupe-eligible. Normal streaming deltas remain
untouched (pure append).

Covers four cases:
- Full overlap: delta already present -> no-op
- Partial overlap: only non-overlapping suffix appended
- No overlap: unchanged append behavior
- Legitimate repeated output (ha + ha -> haha): preserved

jwcrystalandBohdan Triapitsyn 1656c3bb93 perf(sync): optimize multi-session event pipeline with per-directory queues and delta coalescing (#908)
* fix: hide archived section and empty folders when no sessions remain

- Only push archived group in useSessionGrouping when there are archived
  sessions, preventing an empty archived section from rendering
- Hide empty folders in archived bucket via shouldKeepFolder check in
  SessionGroupSection (folders with no sessions and no content in
  children are filtered out)
- Always filter folders through shouldKeepFolder, not just during search

* perf: memoize archived folder filtering

* perf(sync): per-directory event queues to eliminate cross-session HoL blocking

The SSE event pipeline previously used a single global queue and a single
flush timer shared across all directories. Under concurrent multi-session
workloads, a busy directory's delta storm would block other directories'
status and state events from reaching the UI until the next flush tick,
producing the "multi-session latency" symptom users report.

Split the queue into one DirectoryQueue per directory, each with its own
coalesce map, stale-delta set, and flush timer. Directories flush
independently so a busy directory can no longer starve a quiet one. Coalesce
keys are now scoped to a single directory's queue, so the directory prefix
is removed from the key strings.

Cross-directory behavior only; same-directory multi-session behavior is
unchanged (React 18 auto-batching still collapses a single directory's
flush into one render).

* perf(sync): coalesce consecutive message.part.delta events per flush window

Within a 16ms flush window, consecutive delta events for the same
(messageID, partID, field) tuple are string-concatenated into a single
accumulated delta rather than being queued individually.

This directly addresses same-project multi-session workloads — most
notably parent sessions with subagent tasks (child sessions share the
same directory queue). Both parties stream deltas concurrently, which
previously multiplied raw event count proportionally to the number of
active sessions. Coalescing can reduce queue depth by 10-100x during
active streaming.

Safety: verified against event-reducer.ts — the delta handler is a pure
string append (existingValue + props.delta) with no per-event side
effects (no time.updated, no notifications, no diff calculations). The
merged result is semantically identical to applying each delta separately.

The staleDeltas skip mechanism is unaffected: accumulated delta payloads
retain their type and identifiers, so message.part.updated supersession
still works correctly.

* test(sync): cover per-directory queues and delta coalescing

Extend event-pipeline.test.js with behavioural coverage for both
optimizations landed in 98d013a and 258acf0:

P1 (per-directory queues)
- Delivers events from two directories without loss
- Keeps distinct sessionIDs in the same directory as independent coalesce
  slots (session.status is not overwritten across sessions)
- Collapses repeated session.status for the same session down to latest

Option C (delta coalescing)
- Accumulates consecutive deltas for the same (messageID, partID, field)
  into a single dispatched event with concatenated content
- Does not merge deltas across different fields on the same part
- Does not merge deltas across different parts on the same message
- Does not merge deltas across different directories (per-dir queues)
- Skips accumulated deltas when message.part.updated is coalesced onto
  an earlier update, proving staleDeltas still works with C
- Leaves non-delta coalescing (session.status replace semantics) intact

All 13 tests pass under bun:test.

Also adds event-pipeline.bench.js, a runnable synthetic benchmark that
reports delta reduction and byte integrity across 8 workload scenarios
from "single session, 500 tokens" up to "10 projects × 5 sessions ×
1000 tokens". Run with:

  bun packages/ui/src/sync/__tests__/event-pipeline.bench.js

Current numbers on this machine: 99.5% - 99.9% delta event reduction
with full byte-level integrity (concatenated delta bytes always equal
the input total).

* fix(sync): remove staleDeltas — it silently drops delta events

jwcrystalandBohdan Triapitsyn 5584537da5 fix: question tool content disappears after refresh (#879) (#909)
* fix: show question content in ToolPart instead of 'Awaiting response...' after refresh

Previously, when the question tool was pending/running or completed
without parseable output, the ToolPart fell through to a generic
'Awaiting response...' message. After a page refresh or app restart,
this made questions appear empty even though the tool state still
contained the question input data.

Now the ToolPart reads question text, headers, and options from the
tool state's input field, ensuring question content persists across
refreshes regardless of QuestionCard store availability.

Fixes #879

* fix: restore QuestionCard after refresh and pause working status during active questions

Two fixes for question tool UX:

1. ChatContainer: sessionIsWorking now returns false when there are
   active questions (same as it already did for permissions). This
   prevents the status row from showing 'Asking question...' and
   instead shows the QuestionCard.

2. sync-context: resyncDirectoryAfterReconnect now re-fetches
   pending questions via listPendingQuestions(). Previously only
   sessions and messages were re-fetched on SSE reconnect, so
   questions asked during disconnection were lost, causing
   QuestionCard to disappear after page refresh.

Refs #879

* fix: hide assistant working status while questions are pending

The assistant status hook only special-cased pending permissions, so
question tools still surfaced 'Asking question...' after refresh even
when the UI was already waiting on a QuestionCard response.

Treat pending questions like other blocking requests by clearing the
working indicator until the user answers.

Refs #879

* fix: merge question/permission stores instead of full replace on bootstrap and reconnect

The root cause of QuestionCard disappearing after refresh was a race
condition between SSE events and HTTP bootstrap. Bootstrap and reconnect
both did full replacement of state.question, wiping SSE-delivered data
that arrived between the HTTP call initiation and response arrival.

Changes:
- bootstrap.ts: question and permission stores now use merge semantics.
  Only sessions present in the API response are overwritten. Sessions
  absent from the response are left untouched (they may hold SSE data).
- sync-context.tsx: reconnect question resync uses the same merge pattern.
  No longer clears question entries for sessions not in the API response.
- bootstrap.ts: sdk.question.list() now passes directory parameter to
  scope the query correctly.

This ensures SSE-delivered question data survives the bootstrap window,
while still allowing the API response to be authoritative for sessions
it covers.

* fix: prune stale pending requests after reconnect
