- Bun server on port 13337. Serves the client at `/`, upgrades `/ws` to WebSocket.

-

- - `web.ts` owns the Bun fullstack surface only: the SPA HTML shell (dev bundler + HMR / prebuilt `dist/`), the two WebSocket channels (`/ws` chat, `/api/workspaces/ws` live events), and graceful shutdown. Every HTTP API request is delegated to the Hono app via `fetch`.

- - `api.ts` is the Hono REST API (all `/api/*` routes). `withWorkspace` middleware resolves `:id` → workspace (404 if missing) and stashes it on the context, so handlers read `c.get('ws')`. Its catch-all serves the prebuilt client from `dist/` in prod via Hono's `serveStatic` (cached, traversal-safe).

- - `static.ts` exposes the `dist/` location (`DIST_DIR`), the `prebuilt` flag, and the prod SPA `distShell`. `events.ts` holds `publishEvent` (server→client live-event broadcast over `/api/workspaces/ws`) decoupled from `web.ts` to avoid an import cycle; `web.ts` wires it via `setEventServer`.

- - `state.ts` holds global mutable state (messages, session, connected clients). `record()` appends, persists, and broadcasts.

- - `agent.ts` sends prompts to Claude via `query()` from the agent SDK. Streams responses back as typed messages. Sessions are resumable.

- - WebSocket protocol: server sends `ServerMessage`, client sends `ClientMessage` — both defined in `lib/types.ts`.

- - Agent runs in `workspace/` with bypass permissions. Chat history persisted to `workspace/messages.json`.
