The PTY runtime exported an empty NODE_CHANNEL_FD to override the daemon's
IPC descriptor, because bun-pty merges the native environ back into the
child and a JS-only delete does not stick. Node CLIs launched from the
shell (opencode, claude) then printed "warn: Failed to parse IPC channel
number ''" on exit.
The Linux-only env -u ARGV0 wrapper now applies on macOS and Linux and
also unsets NODE_CHANNEL_FD, so the variable is gone instead of empty.
Testing: runtime and inherited-env tests updated for the POSIX wrapper;
verified in the running app that exiting opencode no longer prints the
warning.
Opening the terminal panel sometimes showed stray fragments on the prompt
row: zsh's end-of-line mark and pieces of the prompt path. The shell had
laid its output out for one PTY width, but the client replayed that
history into an emulator of another width (an early size estimate, a
remount, or a renderer rebuild after fonts loaded). ghostty-web's reflow
then left fragments the shell's SIGWINCH redraw never clears.
The server now reports the PTY cols/rows in every snapshot, the transport
carries them through projections and accepted resizes, and the viewport
replays a sized snapshot chunk at that size before returning to the
fitted size. The container-based size estimate only seeds newly spawned
shells and is no longer sent to a running PTY.
Tests cover the sized replay, the store chunk size, the transport
projection, and the server snapshot; verified in a production build by
reloading with the panel open and switching tabs at a changed width.
* fix(sessions): keep a shared chat directory until its last session is deleted
Deleting a root chat session removed its managed scratch directory even
when forks, side threads, or subagents still lived in it; OpenCode then
failed every prompt in those sessions with FileSystem.realPath NotFound.
The directory is now removed only once no other known session resolves
to it. The deleted subtree does not count, because the server cascade-
deletes it, and an unloaded global cache keeps the directory instead of
guessing.
Closes#3312.
* fix(sessions): relocate a session whose worktree directory disappeared
A worktree removed outside OpenChamber, by the agent or by hand, left its
sessions pointed at a path that no longer exists: every terminal create
and restart failed with "Invalid working directory" and the tab stayed
stuck, while Git, Files, and prompts kept targeting the dead path.
The terminal server now names that one rejection (TERMINAL_CWD_MISSING)
instead of substituting a directory of its own. The shared UI reuses the
archived-restore fallback for live sessions: a server-confirmed missing
directory moves the session and its stranded subtree to the project's
primary directory through the control-plane move, clears the worktree
hint, re-selects the session, and tells the user where it went. It runs
from a terminal failure and on activation of any session whose directory
is neither a project root nor a managed chat directory; available,
unknown, and failed probes leave everything untouched.
Closes#3338.
* fix(scripts): make oc-dev load again after the changelog cleanup
The changelog cleanup referenced fs.existsSync in a module that imports
existsSync by name and never binds fs, so every oc-dev invocation failed
with "fs is not defined" before reaching its action.
* fix(sessions): probe directory availability on disk, not through OpenCode path resolution
OpenCode's /path never checks that a directory exists: it echoes the
requested path and resolves its project through Git discovery that
swallows errors, so a deleted worktree came back as a valid location and
every missing-directory fallback (draft recovery, archived restore,
session relocation) stayed inert on a real server. The probe now asks
OpenChamber's own /api/fs/list, which stats the path and reports
not-found and not-directory explicitly; anything else stays unknown.
* fix(sidebar): keep a worktree whose directory is gone visible as missing
git keeps a worktree registered after its directory is deleted outside
git and marks it prunable; the list parser ignored that line, so a
deleted worktree looked alive, and nothing in the app asked for a new
listing anyway. The server now reports prunable, the UI keeps such a
worktree in the topology with worktreeStatus missing and a warning icon
on its sidebar group, and relocating a session out of a confirmed-
missing directory raises an in-app topology signal the sidebar
rediscovers on. Dropping the worktree instead would hide every session
that lived there, and a hidden session can never be opened or relocated.
No idle polling is added.
* fix(sessions): never relocate a session to the filesystem root
OpenCode files a directory outside any Git repository under its global
project, whose worktree is the filesystem root. A managed chat whose
directory vanished would otherwise be moved to /. The relocation now
refuses a root destination, and the activation probe recognizes chat
directories through the home-based check as well, so it does not depend
on the chats root having been resolved yet.
* test(sessions): mirror the relocation action in the issue-2039 session-actions mock
session-ui-store now imports relocateSessionFromMissingDirectory, and the
mocked module in this test listed every other action but not that one, so
the file failed on import.
The tab list lived only in per-tab sessionStorage, so a new browser
tab, another device, or cleared storage showed an empty terminal
sidebar while PTYs kept running server-side, and orphans leaked until
the idle sweep. Add GET /api/terminal/sessions and adopt unknown
server sessions into the local tab projection (additive only; a failed
listing changes nothing).
The idle sweep also reaped terminals in background tabs because only
the active tab holds a WebSocket attachment. Add POST
/api/terminal/touch and have open clients periodically refresh
activity for every session their tabs reference.
Keep ARGV0/env-u assertions from this branch and the DA startup-reply
expectations from main's terminal PTY-before-viewport fix.
Co-authored-by: Serhii Dziupin <makeittech@users.noreply.github.com>
Terminal creation no longer waits for the Ghostty viewport to report its
size: it starts the PTY immediately with a container/font-derived
provisional size (falling back to 80x24), then resizes once the real
viewport dimensions are known, with a dedupe guard while sizing settles.
Starting the shell earlier means it can emit device/theme queries before
a browser terminal is attached to answer them, so the server now answers
primary device attribute queries itself (Fish blocks ~10s on this at
startup) and bun-pty buffers output emitted before a data subscriber
attaches. Also fixes a few WebSocket transport reconnect races surfaced
by session creation now overlapping renderer setup.
bun-pty merges the OS environ into PTY children, so deleting ARGV0 from the
JS env object alone left the AppImage path in the shell. Wrap Linux PTY
spawns with env -u ARGV0, clear native ARGV0 under Bun via libc unsetenv,
and always clear process.env even when no login-shell snapshot exists.

AppImage exports ARGV0 into the process environment. zsh treats that as
argv[0] for every external command, which broke Python venv detection in
the integrated terminal and managed OpenCode sessions.
Clear ARGV0 in Electron before login-shell probing, refuse to re-apply it
from shell snapshots, and strip it from terminal PTY and managed OpenCode
launch environments.

Replace the legacy terminal flow with a shared authenticated WebSocket
runtime used across web, desktop, relay, and mobile surfaces.
- introduce the v3 terminal protocol with scoped attachments, snapshots,
ordered output, bounded replay history, reconnects, and explicit lifecycle
- harden PTY creation, restart, resize, close, force-kill, idle cleanup,
shell selection, login mode, environment sanitization, and appearance sync
- add runtime-aware terminal APIs with relay authentication and Electron parity
- add a fullscreen mobile terminal workspace with touch scrolling,
long-press selection, safe-area controls, quick keys, and Ctrl/Alt input
- add terminal selection attachments, preview detection, project actions,
shell settings, and localized UI
- harden Ghostty rendering, resize recovery, Unicode handling, block
characters, line height, and stale-row behavior
- remove the obsolete terminal SSE path and update reverse-proxy guidance
- expand terminal runtime, transport, input, selection, and store coverage
- avoid duplicate web builds when preparing mobile assets in root CI builds
C.UTF-8 does not exist on macOS, causing the terminal to fall back
to ASCII encoding when LANG is unset. Use en_US.UTF-8 on macOS and
C.UTF-8 on Linux. Also set LC_CTYPE with the platform-appropriate
value (UTF-8 on macOS, C.UTF-8 on Linux) for additional safety.
* 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.

* refactor: extract server modules from monolithic index.js
Split proxy, routes, runtime helpers, and notification emitter
into dedicated modules under packages/web/server/lib/.
* refactor: replace session/message stores with SSE-driven sync layer
Delete ~9200 lines of old architecture (useEventStream, messageStore,
sessionStore, useSessionStore, questionStore, useTodoStore, client SSE).
New sync layer: event pipeline with coalescing + 16ms flush, pure event
reducer, per-directory child stores with LRU eviction, cursor pagination,
optimistic updates, deferred timeline staging, text throttle.
Migrate all UI consumers to sync hooks (useSessionMessages,
useSessionMessageRecords, useSessionStatus, useSessionPermissions, etc).
Strip session-ui-store to UI-only state, delegate SDK ops to
session-actions with abort-if-busy, optimistic store updates, and
response merging for revert/fork/archive/delete.
Add notification-store for SSE-driven session attention tracking,
cross-directory GlobalSessionStatusStore for sidebar indicators,
client-side diff snapshot sanitization to prevent memory bloat,
and revert message filtering via useVisibleSessionMessages.
* feat: notification store, session actions, activity detection
Add notification-store.ts for SSE-driven attention tracking.
Add sanitize.ts to strip diff snapshot memory bloat.
Add session-actions.ts with optimistic revert/fork/archive/delete.
Improve useSessionActivity with incomplete-message fallback.
Delete useServerSessionStatus polling hook.
* fix: add directory param to all SDK calls, fix command/shell/abort routing
All SDK calls in session-actions.ts now pass directory parameter —
required by OpenCode server to scope session operations. Without it,
abort, commands, revert, fork, and other operations returned 500.
Add routeMessage() in session-ui-store for shell mode (session.shell),
slash commands (session.command), and normal prompts. Command lookup
checks both sync child store and useCommandsStore. Handle /compact
locally via session.summarize().
Implement getContextUsage() to restore header context usage display —
reads token counts from last assistant message in sync store.
* refactor: replace custom API proxy with http-proxy-middleware
Remove ~280 lines of custom proxy code: forwardSseRequest,
forwardGenericApiRequest, collectRequestBodyBuffer, header
manipulation, hop-by-hop filtering, SSE block buffering.
Replace with single createProxyMiddleware() call that handles
SSE streaming, large bodies, and timeouts out of the box.
Dynamic router for OpenCode port changes after restarts.
Auth headers injected via proxyReq hook.
Keep: readiness gate, Windows session merge, API prefix detection.
* perf: targeted event draft cloning to fix streaming render cascade
Event handler was eagerly cloning all state slices on every event,
breaking Zustand selector referential equality. During streaming
(~60 events/sec), this caused every subscriber to re-render regardless
of which slice actually changed.
Now only clones fields the specific event type mutates. Also extracts
StatusRowContainer to isolate high-frequency useAssistantStatus
subscription, removes dead messageStreamStatesMap subscription from
ChatContainer, and narrows useAssistantStatus to only track last
assistant message parts.
MessageList renders: 1972 → 296 per streaming session (-85%).
* fix: null safety for sync state slices
Add defensive ?? {} guards on permission, question, session_status,
and message record access. Prevents crashes when child store state
is partially initialized during bootstrap.
* perf: dedup inflight SDK calls, extract concurrency util, delay PR tracking
Extract mapWithConcurrency to shared lib/concurrency.ts. Add in-flight
dedup for loadProviders/loadAgents to prevent concurrent duplicate SDK
calls. Delay initial PR background tracking by 5s to reduce startup
CPU burst.
* fix: header session lookup across all child stores
Session title and context panel click failed when session belonged to
a different directory than the current child store. Fall back to
getAllSyncSessions() to search all initialized stores.

to prevent one failure from blocking the other. Add retry logic to session
API calls and skip large files during diff prefetch to improve performance.

instant feedback. Messages appear immediately in the UI while the API
call executes in the background, with automatic rollback on errors.
