Credentials excluded by default; path traversal validated on restore. - **Profile cloning** — `cloneProfile()` core fn (deep copy + configDir recursive copy), `arc profile clone [--no-copy-dir]` CLI, Shift+C inline clone keybind in ProfilesView. - **Interactive sidebar queue** — combined nav+profile selection in Sidebar with ↑/↓ navigation and Enter-to-launch on profile rows; owner of all sidebar input moved to Dashboard.

Native mode lets Claude paint its own TUI (statusLine, slash commands, etc.); worker mode is for orchestration. - arc launch --native / --worker CLI flags override the profile. - Doctor warns on deprecated CLAUDE_CODE_NO_FLICKER env var. - ProfilesView 'm' keybind toggles mode inline. - LaunchOptions extended so Phase 5+ orchestrators can force worker mode. Phase 0+1 — Agent client (CLI-spawn) foundation: - New packages/core/src/agent-client/: AgentClient interface, per-tool clients (Claude claude -p --output-format stream-json, Codex codex exec --json, Gemini gemini -p), registry ported from agent-forge's agents.json with mcpMode variants. - MCP config injection per mode: config-file (Claude), config-args (Codex TOML-literal), mcp-add pre-launch (Gemini). - Stream parsers tolerate version drift (Codex kind/type discriminators, Claude event envelope unwrap). - 48 unit tests covering parsers, registry, MCP injection, dispatcher. Unblocks Phase 2 (tool registry + agent loop), Phase 4 (arc chat), Phase 5 (roundtable orchestrator), and the Phase 7 dashboard chat.

charset=UTF-8 Content-Transfer-Encoding: 8bit Stream 1 — wiring fixes Root cause: hello-race silenced the chat stream. chat.js sendMessage called ensureHello() synchronously; if the WS wasn't yet readyState=1, hello was a no-op, and the server's broadcastTo(sessionId, ...) silently dropped every chunk because the session was unregistered. - public/components/chat.js: added waitForHello(timeoutMs=5000); sendMessage now awaits it before POSTing /api/chat/message, closing the race. - src/ws.ts: broadcastTo now logs a warning and falls back to broadcast when the target sessionId is unknown. Makes silent failures observable and recoverable. - public/scripts/api.js: postJson / deleteJson / patchJson now attach the bearer token via cached /api/auth/token bootstrap, matching chat.js's authFetch pattern. Fixes 401s on existing sidebar actions (switchProfile, removeAgent, etc.) outside the new views. Stream 2 — visual polish - New public/styles/orchestration.css (~330 lines): toasts, skeleton loaders, CSS-only button spinner ([data-loading="true"]), role pill badges (advocate/critic/neutral/synthesizer), phase-bar animation, empty-state glyphs, help-icon tooltips, kbd styling, focus-visible outlines, .is-hidden utility. - public/index.html: linked orchestration.css. - public/components/chat.js: empty-state glyphs, sidebar skeleton, help icon on MODE, role=log / aria-live on transcript, proper role="dialog" on confirmation modal, #chat-banner placeholder for error surfaces, improved button copy. - public/components/roundtable.js: colored role pill badges in turn headers, synthesizer pill on synthesis block, role="progressbar" on consensus meter, empty states, sidebar skeleton, help icons, #rt-banner placeholder. - public/components/pipelines.js: empty log/history states with glyphs, sidebar skeleton, #pipe-banner placeholder, role=log / aria-label on tracker. Accessibility basics: all interactive elements focusable, aria labels on icon-only buttons, Enter sends in chat, Esc dismisses modals, focus-visible outlines on dark theme. All IDs + data-* hooks preserved. 1274/1274 tests pass; typecheck clean; build 580 KB.

Firefox "can't establish connection to ws://" was the symptom of a silently-died process. Server-side: - src/server.ts: access log per HTTP request (method, status, path, duration). Noisy static assets (/scripts, /styles, /components, favicon) suppressed unless ARC_DASHBOARD_LOG=verbose. Color-coded 2xx/4xx/5xx. Set ARC_DASHBOARD_LOG=off to disable entirely. - src/server.ts: log every WS upgrade attempt with pathname; wrap handleUpgrade in try/catch so invalid upgrades produce a clear stderr line instead of a silent socket destroy. - src/server.ts: clientError handler on the HTTP server surfaces TCP-level protocol errors. - src/ws.ts: log WS session-registration when a client sends hello. Dev-mode crash visibility: - src/dev.ts: process-level uncaughtException + unhandledRejection handlers. EADDRINUSE, unhandled async errors, and anything else that would silently kill the process now print a full stack trace so the user can see why dev:dashboard died. Client-side: - public/scripts/ws.js: after 3 failed WS reconnects, render a fixed banner at top of the page reading "Disconnected from ws://... — is pnpm dev:dashboard still running?" Auto-removes on successful reconnect. Stops users from wondering why the UI is stale. Verified via live test: HTTP, upgrade, and hello frames all log to stderr in dev mode.

Fixes: - src/server.ts stop(): call server.closeAllConnections() + closeIdleConnections() (Node 18.2+) before server.close() to drop lingering browser/client sockets immediately. - src/dev.ts SIGTERM/SIGINT handler: hard-exit fallback after 1.5s so graceful close can't hang the process. tsx's spawn-next-child races the OS port release; faster exit = smaller window. - scripts/kill-stale.js: add --port flag that kills any PID holding the given TCP port, not just tsx/vite/vitepress by command line. Catches zombie processes from prior dev runs. Uses netstat on Windows and lsof on unix. - package.json: predev:dashboard now runs `kill-stale.js tsx --port 3700` so the dashboard always starts from a clean :3700 even after a crashed previous session. Verified via manual restart race: old process SIGTERM → new process binds cleanly → HTTP 200 on /api/health.

Daemon verifies pair_code, stores client pubkey in `clients` table. +- Traffic: every WS frame payload encrypted with `crypto_box(shared_secret)`. Relay sees only opaque bytes + routing header. + +### Relay server (`packages/relay`) + +- Stateless WebSocket multiplexer. Routes by connection pair id. +- No persistence.

Yes if the worker is a tool with persistent session (claude); no if the CLI doesn't support it. Adapter-specific flag. +- **Phase 10:** relay TLS — do we require it (refuse `ws://`) or allow self-signed for LAN? Require `wss://` on relay, allow `ws://` only on 127.0.0.1. +- **Phase 12:** voice mode parity with Paseo — nice-to-have or MVP?

TUI, dashboard, and CLI are all clients. Zero direct adapter calls outside daemon. +3. `arc run claude "hello"`, `arc ls`, `arc attach `, `arc stop ` work end-to-end. +4. `arc loop` completes a full worker/verifier cycle with cross-provider verify. +5. Chat rooms: two agents post/read/mention each other. +6. Mobile app (TestFlight + Play internal): can attach to a remote daemon via relay and stream terminal output. +7. Docker image boots a headless daemon reachable from the mobile app. +8. `arc migrate v2-to-v3` ingests a real v0.4.0 `~/.arc/` without loss. +9. v3 docs site updated; `paseo.sh`-equivalent page published. +10.

Windows to avoid ENOTEMPTY SQLite WAL/SHM files and the daemon log stream briefly hold Windows file handles after close(), so the afterEach cleanup races with the file-system and fails with ENOTEMPTY on CI. Adding maxRetries + delay lets those handles release before we try again. Linux/macOS unaffected.
