* perf: drastically improve cold-start, bundle size, and streaming performance
Cold-start optimizations:
- main.tsx: Remove blocking await on prefs I/O — render immediately with
defaults, hydrate persisted settings asynchronously. Cuts 50-200ms from
time-to-first-paint.
- bootstrap.ts: Split directory bootstrap into 3 phases:
* Phase 1 (blocking): path, config, provider, session status — minimum
data needed to render UI. Mark status complete after this phase.
path.get and session.status must both succeed; they have no fallback.
* Phase 2 (deferred): agents, commands, mcp, lsp, vcs, questions,
permissions — fetched after first paint without blocking.
* Phase 3 (lazy): session messages — loaded without blocking init.
- App.tsx: Keep identical provider tree before/after init to prevent
full subtree remount when isInitialized flips. FireworksProvider and
VoiceProvider are lightweight shells; overlays deferred until init.
Bundle-size optimizations:
- App.tsx + MainLayout.tsx + VSCodeLayout.tsx: Code-split heavy views
(SettingsView, GitView, DiffView, TerminalView, FilesView, PlanView,
OnboardingScreen, SettingsWindow, MultiRunWindow) with React.lazy.
Views load on demand when user switches panels.
- vite.config.ts: Lower chunkSizeWarningLimit from 1200KB to 500KB.
Streaming render optimizations:
- streaming.ts: Throttle streaming store writes ~60Hz → ~1Hz. Busy-session
only scan (Set, O(1)).
- MessageList.tsx: Lower virtualization threshold 40 → 15.
- ChatMessage.tsx: React.memo with areRenderRelevantMessagesEqual.
- MarkdownRenderer.tsx: React.memo with explicit prop comparators.
* fix: address Greptile review feedback on bootstrap and provider tree
- bootstrap.ts: Tighten Phase 1 error guard. path.get and session.status
must both succeed; they have no global fallback.
- bootstrap.ts: Replace dead .catch() on Promise.allSettled() with .then()
that inspects individual results for errors.
- App.tsx: Keep identical provider tree before/after init to prevent full
subtree remount when isInitialized flips.
* perf: lazy-load heavy dependencies (MarkdownRenderer + CodeMirror languages)
MarkdownRenderer dynamic import:
- Move heavy implementation (marked, react-markdown, beautiful-mermaid,
react-syntax-highlighter, ~1500 lines) to MarkdownRendererImpl.tsx
- Replace MarkdownRenderer.tsx with thin lazy wrapper using React.lazy
- All 11 existing imports work unchanged — no consumer code modified
- Full markdown stack loads on first render of markdown content
CodeMirror language lazy loading:
- languageByExtension.ts: remove static imports for 10+ less-common
language packages (@codemirror/lang-go, lang-rust, lang-sql, etc.)
- Keep only 6 most common languages static: javascript, json, css, html,
markdown, python, shell
- Less common languages return null from languageByExtension, causing
callers to fall back to loadLanguageByExtension which dynamically
loads from @codemirror/language-data
- Reduces initial bundle by ~200KB+ of language parsers

Security note: binding to 0.0.0.0 exposes the server on all network interfaces — use only on trusted networks and protect with firewall rules or --ui-password.
Managed-local path note: OPENCHAMBER_TUNNEL_CONFIG must use a container path under /home/openchamber/.... If the config file references credentials-file, ensure that JSON path is also mounted and reachable inside the container.
Data directory: mount data/ for persistent storage. Ensure permissions:
openchamber # Runs in background by default
openchamber stop # Stop background server
systemd service (VPN / LAN access)
Use --foreground to keep the CLI process alive so systemd (or any other process manager) can track and restart it. Combine with OPENCODE_HOST to connect to an OpenCode instance running as a separate service.
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.
%t expands to $XDG_RUNTIME_DIR (e.g. /run/user/1000), where most SSH agents write their socket.
--host 0.0.0.0 is required to listen on all interfaces (the default is 127.0.0.1). Use --host <ip> or OPENCHAMBER_HOST=<ip> to bind to a specific interface instead.
