* feat: add draw.io diagram editor integration
Embed draw.io editor via react-drawio (MIT, zero deps) for inline
editing of .drawio files. Changes auto-save to disk. Includes
inline editor in FilesView with Visual/Source toggle, dark mode
support, template picker for new files, and chat file attachment
integration.
* fix: debounce diagram autosave to prevent reload loop
* fix: ignore watcher-triggered xml prop changes to prevent reload loop
* fix: remove auto-save-to-disk, add manual save button for diagrams
Autosave writes triggered file watcher cascade that reloaded the
draw.io iframe and reset zoom. Replaced with explicit Save button
in the toolbar (floppy disk icon). Editor XML is stable on mount
and ignores watcher-triggered prop changes.
* fix: remove auto-save write from DiagramView, add save button
* fix: hide draw.io save/exit buttons in editor
* fix: also hide save-and-exit button
* fix: brighten save button styling, add saved confirmation
* fix: remove autoSaveStatus toggle on diagram save to prevent toolbar collapse
* fix: add local save confirmation state for diagram button
* fix: remount drawio iframe on theme change, persisting XML across mounts
* fix: clear persisted xml on mount to prevent leaking between files
* fix: initialize dark mode synchronously, preserve edits across theme remount
* fix: auto-focus drawio iframe on mount/theme-change for keyboard shortcuts
* fix: add diagram i18n keys to Traditional Chinese locale
* fix: restore upstream HMR host and LAN address support
* fix: load sub-agent sessions on bootstrap for sidebar visibility
Two-phase session load: first fetch root sessions (for accurate
sessionTotal), then fetch all sessions and include child sessions
(sub-agent delegations). This ensures sub-agent sessions appear
in the sidebar immediately instead of relying on the async global
session store.
* remove opencode-drawio from PR branch
* fix: atomic file writes to prevent concurrent read/write truncation
Three-layer defense against the O_TRUNC race:
1. Write side (server): replace direct writeFile with write-to-temp-
then-rename. fs.rename is atomic on POSIX.
2. Read side (server): retry up to 3 times with 50ms backoff when
readFile returns empty but stat reported non-zero size.
3. FilesView client: refuse to save empty draftContent when the
original fileContent was non-empty.
* fix(dev): clean up orphaned OpenCode processes on Ctrl+C
* fix: allow empty file saves, log warning instead of blocking
Replaces the hard block on saving empty content with a console.warn.
The atomic write + read retry on the server side handle the O_TRUNC
race properly. The previous guard caused a UX regression by silently
preventing users from clearing a file and saving.
* fix: remove time window from sub-agent fallback for live tasks
While a task tool is active, the fallback now matches any session
with the correct parentID regardless of creation time. This allows
late-appearing child sessions to be found when the OpenCode server
is slow or the SSE event pipeline is delayed. The time window is
still applied once the task tool has completed, as a final sanity
check.
* fix: three diagram editor bugs from Greptile review
1. stableXmlRef now resets when xml prop changes — switching
between .drawio files renders the correct content.
2. Focus effect only runs on mount, not on isDark changes —
theme toggle no longer steals keyboard focus 600ms later.
3. saveDiagram updates xml state after writing — dirty-check
guard works correctly for subsequent saves.
* fix: route session.created SSE events to correct directory
Three-layer fix for sub-agent sessions not appearing in sidebar and
inline chat:
1. protocol.js: parseSseEventEnvelope now extracts directory from
properties.info.directory (where session.created/updated events
carry it) in addition to properties.directory. WS frames relayed
to the browser now carry the real directory instead of 'global',
so child sessions routed to the correct directory store.
2. event-pipeline.ts: same fallback in resolveEventDirectory for
defense-in-depth when SSE events bypass the WS relay.
3. resolveFallbackTaskSessionId.ts: time window lower bound now
allows 2s grace before taskStartTime to accommodate server timing
jitter (child session creation timestamps consistently precede the
tool's recorded start by ~6-9ms), fixing the 'Open subtask'
button not rendering in OpenChamber's inline chat.
* fix: sub-agent sidebar visibility, file zeroing guard, inline badge fallback
- Sync watchdog: periodic child session discovery poll (every 15s) detects
sessions created by other OpenCode instances, triggers parent materialization
- protocol.js: parseSseEventEnvelope extracts directory from
properties.info.directory for session.created/updated events
- event-pipeline.ts: same fallback in resolveEventDirectory for defense-in-depth
- resolveFallbackTaskSessionId: don't require taskStartTime (cross-OpenCode);
pick most recent child when multiple idle candidates exist
- readTaskSessionIdFromOutput: parse <task id="ses_xxx"> format from output
- FilesView: reinstate empty-draft guard (block save when draftContent='' but
fileContent had content) to prevent file zeroing on tab switch
* Fix diagram autosave reload loop
* Highlight drawio files as XML
* Use diff-compatible highlighting for drawio files
* Restore drawio file icon mapping
* Stabilize drawio source preview toggle

startup enable snapshots your current environment into the native service so startup behaves like you launched openchamber from the same shell. This preserves provider tokens, PATH, SSH agent settings, and other CLI auth/config env vars. Use --no-env-snapshot if you want a minimal service env.
This runs OpenChamber as an API-only server without the desktop app or browser UI assets on that machine, then creates a link for Desktop to import. --lan makes the server reachable from other machines. --server is the address Desktop should use.
When OpenChamber was started with --lan or --host 0.0.0.0, connect-url automatically uses a detected LAN IP instead of 127.0.0.1. Use --server http://host:3000 to override the advertised address, and include --lan when connect-url needs to start the server for LAN access.
Paste the printed openchamber://connect?... link in Desktop under Settings -> Remote Instances -> Direct Instances -> Import Link. The link contains the server URL and a client token. It does not enable browser UI password protection; use --ui-password when exposing a server beyond localhost.
systemd service (VPN / LAN access)
Run OpenChamber and OpenCode as separate persistent services — useful when you want to access your
dev machine over a VPN (e.g. Tailscale) or LAN without a Cloudflare tunnel.
How it works:
OpenCode runs as its own service, binding only to localhost.
OpenChamber connects to it via OPENCODE_HOST and --lan makes it reachable on your VPN IP.
--foreground keeps the CLI process alive so systemd can track and restart it.
Why set PATH and SSH_AUTH_SOCK?
systemd user services start with a minimal environment — no shell profile is sourced.
Without an explicit PATH, OpenCode won't find tools installed via Homebrew, npm, or ~/.local/bin.
Without SSH_AUTH_SOCK, git operations over SSH (push, pull, clone) will fail because the agent socket isn't inherited.
Adjust the PATH to match your own tool installation paths.
%t expands to $XDG_RUNTIME_DIR (e.g. /run/user/1000), where most SSH agents write their socket.
OpenChamber will be reachable at http://<your-vpn-hostname>:3000 from any device on your VPN.
Note:--host 0.0.0.0 is required to listen on all interfaces. The default
bind address is 127.0.0.1 (localhost only). Use --host <ip> or
OPENCHAMBER_HOST=<ip> to bind to a specific interface instead.
Managed-local path note: OPENCHAMBER_TUNNEL_CONFIG must point to a path inside the container user home (/home/openchamber/...). If your Cloudflare config references a credentials JSON file, that file path must also be accessible inside the container (mount with volumes).
Website docs source lives at packages/docs/content/docs/reverse-proxy.mdx.
Tunnel behavior notes
OpenChamber supports one active tunnel per running instance (port).
Starting a tunnel with a different mode/provider on the same instance replaces the current tunnel.
Replacing or stopping a tunnel revokes existing connect links and invalidates remote tunnel sessions for that instance.
Connect links are one-time tokens; generating a new link revokes the previous unused link.
Data Directory Permission Note: The data/ directory is mounted into the container for persistent storage (config, sessions, SSH keys, workspaces). Before running, ensure the directory exists and has proper permissions:
