Replace local-only filtering in GitHub issue/PR picker dialogs with
server-side GitHub Search API queries. Search text is sent as a query
parameter to the server, which uses the GitHub Search API
(issuesAndPullRequests endpoint) with repo: qualifiers including fork
network support. Results are debounced at 350ms to respect API rate
limits.
- Add query parameter to GitHubAPI issuesList/prsList interface
- Server routes use Search API when query is present, standard list
endpoint when absent
- Fork networks handled via repo:owner/repo OR repo:owner/upstream
- PR search fetches full PR details after Search API for head/base/draft
fields
- Remove local filter memos from all three picker dialogs
- Add debounced search effect with abort controller cleanup
- Update VS Code backend and webview API for parity
- Update search placeholders in all locales
Closes#1350

Add a directory-created fast path for worktree creation so session and send flows can continue once the target directory exists while Git attachment and bootstrap finish in the background.
Track bootstrap status explicitly in shared UI contracts, including pending, ready, and failed states. Background watchers now surface failures and timeouts, update stored worktree metadata, and keep web and VS Code runtime behavior in parity.
Move GitHub issue/PR worktree sessions and assistant-answer fork sessions onto the unified send path so provider, model, agent, and variant selections are preserved. The assistant-answer fork dialog can optionally create a worktree outside VS Code.
Make worktree deletion dialogs close after linked-session cleanup while removing the worktree in the background, and clean up failed fast-create artifacts safely without recursively deleting user or agent-written files.
Validation: bun test packages/ui/src/lib/worktrees/worktreeBootstrap.test.ts packages/ui/src/lib/worktrees/worktreeManager.test.ts; bun run type-check; bun run lint.
Add shared time formatting helpers that apply the Appearance time format preference consistently. Update visible time labels across chat, quota usage, scheduled tasks, tunnels, context details, git views, PR metadata, and passkey settings to use the selected 12-hour, 24-hour, or automatic format. Leave date-only and non-UI formatting untouched so unrelated behavior does not change.
Preserves session directory metadata across live updates
Keeps desktop and mobile session lists in project groups
Adds regression coverage for session grouping
Add a toggle for displaying archived sessions in the sidebar menu
Load more sessions in smaller increments
Reset expanded session counts when collapsing groups or projects
* feat: add dialog for "Start new session from this answer"
Replace the one-click fork action on assistant messages with a dialog
(ForkSessionDialog) that lets the user pick model, thinking level, and
agent, plus edit the instructions sent to the new session.
The instructions field is prefilled with the previous fixed fork prompt
and is mandatory. The composed message is now fully visible (no synthetic
preface): the user's instructions sit above a short fixed connective that
opens the assistant content. createSessionFromAssistantMessage takes the
chosen execution params instead of reading from config.
Also fix TodoSendDialog visuals: narrower vertical layout, model trigger
no longer stretches with centered text, and the agent/thinking dropdowns
portal to body so opening them no longer nudges the dialog height. Extract
the shared ThinkingPill into its own component.
* fix: address review feedback on fork session dialog
- Fix "bellow" -> "below" typo in the fork content preface (now user-visible
since the message is no longer synthetic)
- Reset ForkSessionDialog state only on open transition, reading the config
store snapshot via getState() so background store refreshes can't discard
in-progress instruction edits
Add a packaged-client runtime boundary so the shared UI can talk to local,
desktop, remote, and VS Code runtimes through the right transport instead of
assuming one same-origin web server.
Centralize OpenChamber-owned API access behind RuntimeAPIs, runtimeFetch, and
runtime URL helpers, while keeping official OpenCode traffic on the SDK path.
Support runtime switching, remote host selection, desktop client credentials,
and headless connection links for pairing packaged clients with remote
OpenChamber servers.
Harden the new auth model by moving long-lived client tokens out of browser
URLs, introducing short-lived scoped URL tokens for browser-owned transports,
restricting URL-token access to explicit readable/realtime routes, and making
client-token management session-scoped or self-scoped as appropriate.
Update browser-owned assets and preview proxy flows to work with the split
runtime model, including authenticated project icons, preview token propagation,
CSP-safe preview bridge injection, and preview proxy auth that survives
short-lived URL-token expiry.
Tighten Electron security boundaries for packaged clients by gating privileged
preload state to trusted origins and requiring explicit confirmation before
connect deep-links import or switch remote runtimes.
Also refresh agent guidance and project skills so future runtime/API, auth,
preview, UI, CLI, settings, locale, and drag-to-reorder work follows the new
architecture.

* fix: session rename exits immediately due to focus race
Replace fragile onBlur handler with document mousedown listener for click-outside detection. Defer dropdown-initiated rename to onOpenChangeComplete (fires after CSS transition + cleanup). Use finalFocus instead of dead onCloseAutoFocus (never forwarded to Base UI).
* chore: remove dead editCancelledRef after onBlur removal
onBlur was replaced by document mousedown listener. editCancelledRef was only read in the old onBlur handler — its write in the Escape key handler was the sole remaining use.
* fix: resolve symlinks in project directory paths
OpenCode stores sessions using the canonical (realpath) directory, but
OpenChamber passed the unresolved symlink path in several places. The
string-match directory filter would fail when a project was accessed via
a symlink, making sessions invisible.
Changes:
- Add safeRealpathSync to settings normalization — project paths and
lastDirectory are canonicalized at persistence time
- Add Express middleware before the API proxy to resolve symlinks in
?directory= query params on in-flight requests
- Resolve symlinks in /api/fs/list so the directory browser returns
canonical paths, allowing the "already added" check to work correctly
- Reconcile the in-memory projects store when the server responds with
normalized paths, preventing temporary duplicates

* perf(git): cache project-root resolution to stop N² polling cascade
Opening a workspace with many projects/worktrees fired hundreds of
`POST /api/fs/exec` requests (e.g. ~700 for 19 projects) within seconds,
dominated by repeated `git rev-parse --absolute-git-dir` /
`--git-common-dir` for the same directories.
Root cause: in `useProjectRepoStatus`, each project's `ensureStatus`
settles independently and mutates the git store, which re-derives
`projectGitBranchesKey` and re-runs `getRootBranch` for *all* projects on
every change. `getRootBranch` had no caching, so this produced an N×N
burst of uncached git plumbing calls.
Changes:
- worktreeStatus: extract `resolveProjectRoot` to module scope with a
60s TTL cache + in-flight dedupe (root resolution is static within a
session). Combine the two `rev-parse` queries into one subprocess.
Add `getRootBranch(dir, { knownBranch })` fast-path that skips a
redundant git status when the directory is its own root, while still
resolving the primary-root branch correctly for linked worktrees.
Export `invalidateResolvedProjectRootCache`.
- useProjectRepoStatus: replace the cascade effect with a debounced,
diff-based pass that only resolves projects that are new or whose
branch actually changed, passing the known branch through.
- worktreeManager: invalidate the root cache on worktree create/remove.
- Add unit tests for caching, dedupe, invalidation, rev-parse
precedence, non-git fallback, linked-worktree resolution and the
knownBranch fast-path.
Reduces startup from hundreds of requests to roughly one root
resolution per project.
* fix(git): clear in-flight resolves and guard write-back on cache invalidation
`invalidateResolvedProjectRootCache` cleared `resolvedRootCache` but left
`inFlightRootResolves` intact, so during a worktree topology change a
resolution already in flight could (1) be handed to callers arriving after
invalidation and (2) re-seed the cache with the pre-invalidation root when it
settled, defeating invalidation for up to the full TTL.
Drop the in-flight entry on invalidation and add an epoch guard so a resolve
that was invalidated mid-flight does not write its now-stale result back.
Add a regression test for the concurrent-invalidation scenario.
* fix(git): bound root cache and avoid early sidebar resolves
* feat: rename sessions inline via double-click
Double-clicking a session name in the sidebar or the mobile session
status bar now switches it into an inline editable input. Enter saves,
Esc cancels, and clicking elsewhere blurs the input to save. This
mirrors the VSCode/Finder rename pattern and removes the need to open
the session menu for what is a very common action.
* fix(rename): close sidebar input on empty title; drop duplicate mobile editor
Two issues from PR review:
1. handleSaveEdit (sidebar) only closed the input when editTitle.trim()
was non-empty. Clearing the title and pressing Enter or blurring left
the input open with no exit path other than Escape. The save handler
now always closes the editor; an empty title is treated as a silent
cancel (no update call).
2. ExpandedView (mobile) renders the current session twice — once in the
sticky header, once in the session list — so a single editingSessionId
produced two simultaneous inputs for the current session. The list row
for the current session now suppresses its rename input; the header
remains the single editor in that case.
* fix: refine inline session rename editing

Replace the prompt-template workflow with snippet support that is compatible with opencode snippet conventions. Snippets are now stored and loaded from global and project snippet directories, including legacy pluralized paths, with frontmatter metadata for aliases and descriptions. Snippet expansion supports recursive references plus prepend and append sections, while inject sections are treated as unsupported no-ops so OpenChamber remains compatible without requiring an external plugin.
Add the snippets settings experience and remove the old prompt-template settings surface. The new settings page and sidebar support creating, editing, deleting, selecting, and describing snippets, with localized copy across every supported locale. The settings navigation now exposes Snippets with a dedicated icon and metadata.
Wire snippets into all prompt-entry surfaces that need them. Chat, multi-run groups, and scheduled task prompts now offer hash-trigger snippet autocomplete and expand snippets before sending work to OpenCode. Chat also uses an adaptive compact placeholder on mobile or narrow composer widths so helper trigger guidance stays readable in constrained layouts.
Keep multi-run aligned with grouped prompts. Multi-run sessions now use a shared title builder that handles both legacy titles and the newer g1, g2 prompt-group title format. Fusion parsing now recognizes grouped multi-run titles, scopes fusion sources to the same prompt group, and creates fusion sessions under the matching group so outputs from different prompts are not mixed accidentally.
Harden the icon sprite pipeline. The sprite generator now discovers icon names used through typed icon maps, JSX icon props, IconName returns, and generated-value flows without scanning unrelated string literals or the generated sprite itself. The generated sprite is strictly typed so invalid icon names are caught by type checking, and existing invalid or unsafe icon references were cleaned up across settings, provider, Git identity, scheduled task, voice, header, and sidebar surfaces.
Update backend configuration routes and documentation for snippets. The OpenCode config route layer now exposes snippet CRUD and expansion endpoints, accepts JSON bodies for snippet writes, and removes the old prompt-template provider. Scheduled task runtime expansion now uses snippets before dispatching messages.
Add regression coverage for snippet storage and expansion, config-route JSON handling, and multi-run title parsing. Validated with full type checking, full linting, targeted multi-run title tests, and targeted OpenCode snippet/config route tests.
Improve chat session switching and history pagination, with most of the aggressive limits scoped to the VS Code webview where the freezes were observed.
Session history loading and pagination:
- Reduce the VS Code message page size to 30 records so switching sessions does not immediately hydrate large histories into the webview.
- Keep manual Load older messages in VS Code fixed at 30 records per request instead of growing the request size over time.
- Add a bounded VS Code initial-tail expansion path from 30 to 50, 80, and 120 records only when the initial page has no user-message turn boundary, preventing large final turns from rendering as an empty chat.
- Lower the normal web message page size from 200 to 150 for a mild shared optimization without adopting the aggressive VS Code limits.
- Make session pagination metadata reactive per session so ChatContainer receives cursor updates from materialization and reconnect paths without requiring a switch away and back.
- Write pagination metadata before publishing newly materialized messages so the first render sees the correct has-more state.
- Store cursor information from direct materialization and reconnect message fetches in the shared session prefetch metadata cache.
VS Code cache and memory pressure reductions:
- Use a shared per-directory session recency map so cache eviction is based on app-level recency instead of whichever useSync instance happened to run.
- Limit VS Code warm session cache retention to 4 sessions and evict heavy inactive message caches after switching away from a large session.
- Disable sidebar session prefetch in VS Code because warming extra sessions was increasing webview memory and GC pressure during navigation.
- Remove dropdown background message prefetch so opening the switcher does not start additional session materialization work.
- Drop cached session-message-record snapshots when evicting session data so stale derived records do not remain after the raw session cache is cleared.
- Add bounded LRU caching for session message record snapshots, with much smaller VS Code limits and a VS Code cap that avoids caching snapshots above 30 messages.
- Bound the turn-window model cache in VS Code and avoid caching turn models for sessions above the VS Code message-page size.
Chat render-path reductions:
- Reuse ChatContainer's already-materialized message records in plan detection instead of adding a second active-session message subscription.
- Add a no-op guard when marking session plan availability so repeated detections do not create new Map references and fan out renders.
- Add no-op guards for session switcher and dropdown open state updates to avoid unnecessary store updates and renders.
- Convert several session-specific hooks to useSyncExternalStore with empty-session no-subscribe behavior so empty IDs do not subscribe to broad store updates.
- Remount the chat viewport when the current session changes, isolating per-session viewport and list state.
- Change the virtualized message-list fallback to render only a tail window when the virtualizer has not produced rows yet, instead of rendering an entire large history.
VS Code layout and header improvements:
- Remove the broad useSessions subscription from the VS Code layout header path and subscribe only to the active session title and initial-session existence.
- Unmount the compact VS Code session sidebar when the user is in chat view instead of keeping the hidden session list mounted and subscribed.
- Compute the latest assistant model and latest context-token usage in a single reverse scan of current-session messages instead of scanning the same list twice.
- Remove switcher git-status warmup work so the switcher reads already-loaded branch labels without starting extra background git status requests.
Markdown and file-reference safeguards:
- Skip expensive syntax highlighting for very large code blocks, with a 200-line cap in VS Code and a softer 1200-line cap in web.
- Add an LRU cap to file-reference stat lookups so the cache cannot grow without bound across many rendered messages.
- Limit the number of file references annotated per render to 40 in VS Code and 200 in web to prevent large assistant outputs from spawning too many stat checks.
- Clear file-link annotations when file-reference mode is disabled so stale attributes and handlers do not remain on previously annotated nodes.
Assistant-message action and preview reductions:
- Skip preview URL scanning on VS Code, mobile, and mini-chat surfaces so assistant text and tool output are not scanned where the preview action is unavailable.
- Skip Save-as-Plan project lookup on VS Code, mini-chat, and mobile surfaces.
- Hide Save-as-Plan and Start MultiRun assistant-message actions on VS Code, mini-chat, and mobile surfaces.
- Resolve the current session directory on demand for assistant actions instead of subscribing each assistant message to the full session list.
Tool and task rendering optimizations:
- Prefer finalized task metadata summaries without fetching child-session messages when the summary is already present.
- Avoid polling or final-fetching task child sessions once a final metadata summary is available.
- Use VS Code-specific task child fetch limits of 30 records for initial, active, and idle fetches.
- Parse diff stats by scanning patch text line-by-line instead of splitting large patches into arrays.
- Count write-tool lines by scanning content instead of allocating a split array for large files.
- Avoid trimming large patch strings just to test whether they contain content.
- Memoize diff and write statistics so unchanged tool parts do not recalculate them on every render.
VS Code bridge improvements:
- Return JSON and text proxy responses through the VS Code bridge as bodyText instead of base64 so the webview avoids synchronous base64 decoding for common API responses.
- Keep binary responses on the base64 path while making bodyBase64 optional in the bridge contract.
- Strip content-length, content-encoding, and transfer-encoding headers from proxied responses because the bridge reconstructs the Response body.
Validation:
- bun run type-check
- bun run lint
- bun run vscode:build
Header now spans the full window width above the [sidebar | chat | right-sidebar] row instead of nesting inside the central column. The chat area becomes a self-contained framed window with its own border and rounded corners on all four sides, and sidebars sit flush against the header sharing its bg-sidebar so the seam is invisible.
Removed the duplicated shell controls the old layout needed to fake header-height inside sidebars: portal host on RightSidebar, paddingTop reservation, top drag overlay, duplicated layout-left / chat-new buttons in SidebarHeader, the showDesktopSidebarChrome block in SessionSidebar, and the conditional traffic-lights inset on the desktop header. Mac WCO inset now lives only on the header.
Moved the new-session action into the SessionSwitcher dropdown as its first item, removed the standalone chat-new button from the header, relocated scheduled-tasks into the left action group of the sidebar header, and bumped ContextPanel tab strip to h-10 to balance the more prominent header.

Targets active editor chat before falling back to sidebar
Adds session open-in-editor action in the VS Code sidebar
Uses attachment badges for VS Code file and selection context
* fix(sessions): align archive-cascade count with executed list
When archiving a parent session, the dialog showed the total descendant
count but the actual archive request skipped already-archived
descendants — so the toast/result didn't match what the user was told.
Collect descendants once, then filter per-action: hard-delete cascades
to every descendant; archive skips already-archived ones. Dialog count
and the ID list passed to archiveSessions/deleteSessions now agree.
* fix(sessions): snapshot descendant IDs at dialog open
Address Greptile review: handleDeleteSession populated the dialog
count from a fresh collectDescendants() call, then confirmDeleteSession
re-collected at confirm time — so a background sync that mutated
childrenMap while the dialog was open could re-introduce the same
count-vs-executed mismatch this PR fixed.
Store the computed descendant IDs in deleteSessionConfirm and pass
them through to executeDeleteSession, so the executed list is always
the snapshot the user was shown. The no-dialog direct-execute path
also routes through the snapshot for consistency.

The archived bucket is the only sidebar group that routinely grows
into the hundreds or thousands of rows (projects accumulate archived
sessions over time). On main, expanding the bucket mounts every row
at once — for a project with ~1400 archived sessions that's
thousands of subscriptions, layouts, and event handlers committed
on a single render.
Wrap the archived bucket's row map in `@tanstack/react-virtual`
(already in deps) when the visible count crosses 50. DOM stays
bounded to the visible window + overscan regardless of total size.
Implementation notes:
- Threshold + estimate are local constants; only the archived
bucket is gated, every other group keeps its eager render.
- The virtualizer needs a scroll element. The sidebar's scroll
lives on an ancestor `ScrollableOverlay`; rather than threading
a ref through every intermediate component for this one use
case, we walk up the DOM from the row container.
- `measureElement` handles variable row heights (subagent
expansion, status indicators, etc.).
- ResizeObserver re-measures on sidebar resize, mirroring the
pattern in ChangesSection.

The same session can appear in two render contexts at once — most
visibly under "Recent" and under its project's root group. Expansion
state was keyed by bare session id, so toggling the chevron in one
context flipped it in the other; the user clicked one row and a
duplicate elsewhere expanded/collapsed in sync.
Switch the expansion set to composite keys of the form
`<renderContext>:<active|archived>:<sessionId>`. SessionNodeItem
already computes this exact shape for its menu instance key
(menuInstanceKey); reuse it as expansionKey so the two render-time
instances of one session keep independent expand state. Updated:
- isExpanded reads `expandedParents.has(expansionKey)`.
- Chevron click / Enter / Space pass `expansionKey` to toggleParent
instead of session.id.
- The memo-equality check compares the same composite key on both
sides so it correctly re-renders when only one context's state
changes.
- toggleParent's parameter is renamed `expansionKey` to reflect the
new shape; the implementation is unchanged.
- The auto-expand-parent-on-subagent-navigation effect doesn't know
which context the user will look at the parent in, so it fans the
parentID out to all four (project|recent) × (active|archived)
combinations.
Storage is bumped to `oc.sessions.expandedParents.v2`. Existing v1
data (bare session ids) is one-shot migrated by fanning each id
across all four contexts and rewritten under the v2 key; the v1 key
is then removed so a downgrade-then-reupgrade doesn't re-migrate.

The previous system layered three hooks (useScrollEngine, useChatScrollManager,
useChatTimelineController) with overlapping responsibilities, four parallel
ResizeObservers/MutationObservers, and six entry points to "scroll to bottom"
(force-flag combinations, persistent follow loops, materialization recovery).
This produced bugs where users could not break free of auto-follow during
streaming: scrollbar drag, keyboard scrolling and find-in-page were not
detected as user intent, and observers kept restarting the follow loop on
every DOM mutation.
The new architecture replaces the two low-level hooks with a single
useChatAutoFollow that owns scroll behaviour end to end:
- One state: 'following' or 'released'. No follow modes, no pin flags,
no marker pixels.
- One scroll writer: a lerp loop that runs only while the session is
streaming and state is 'following'. Idle sessions never write scrollTop
programmatically.
- One user-intent detector: wheel up, touch drag down, keyboard
(PageUp / Home / ArrowUp), pointerdown on the OverlayScrollbar thumb,
and explicit releaseAutoFollow() calls all flip the state to 'released'.
- A 1.2s grace period after explicit release: re-pin will not auto-engage
inside this window, so a small wheel up cannot snap the user back even
while they remain near the bottom spacer.
- Re-pin and the scroll-to-bottom button share the same threshold: the
height of the empty bottom spacer (10vh on desktop, 40px on mobile).
Released users see the button only after they have scrolled past the
spacer that already exists at the end of the chat.
- Save/restore of scroll position uses ratio mapping, debounced at 150ms
on user-driven scroll events; programmatic writes are masked via a short
window so they never persist as user positions.
- Container reattachment is detected via a useLayoutEffect probe over
scrollRef.current. Listeners and observers re-bind when ChatViewport
mounts after hydration or after the first message promotes a draft
session into a real chat.
- A pending-restore queue replays restoreSnapshot once the scroll
container appears, fixing the case where a hydrating session landed at
the top instead of the bottom.
Removed: useScrollEngine.ts, useChatScrollManager.ts, the persistent
follow loop with its own ResizeObserver+MutationObserver pair, the
materialization-recovery .finally resume that yanked idle users to the
bottom on transient sync gaps, and the openchamber:session-reselected
event (re-select still works through the existing onSessionSelected
callback). The openchamber:chat-force-scroll-bottom event remains for
synthetic-message paths like git-message generation.
Net change: ~1300 lines removed, two hooks replaced with one, one
observer pair instead of four.
Add dedicated Electron Mini Chat windows for focused chat sessions without the full desktop shell. Mini Chat can open existing sessions or draft sessions, supports pinning above other windows, transfers sessions or drafts back to the main window, and deduplicates existing-session windows.
Expose Mini Chat entry points from the main header, session sidebar, command palette, and `mod+alt+n`. Add a dedicated Vite entry and React runtime so the compact surface can stay isolated from full-app chrome while still sharing chat, sync, theme, locale, model, agent, and worktree behavior.
Keep Mini Chat behavior scoped to the compact surface:
- limit assistant/user message actions to the appropriate Mini Chat set
- hide workspace changed-files UI in Mini Chat
- keep draft worktree selection and streaming directory state in sync
- mark sessions viewed while they are open in Mini Chat
- support Mini Chat-specific keyboard shortcuts for input focus, model selection, thinking variant cycling, favorite model cycling, and opening new Mini Chat drafts
Harden Electron integration by gating Mini Chat controls on desktop IPC availability, restricting pin/unpin IPC to Mini Chat windows, and only closing Mini Chat after the main window handoff succeeds.
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.
