+# BooCode v1.1 — Batch 10
+
+**Theme:** BooTerm. Second container, dedicated to in-browser terminals. Per-session tmux. xterm.js + node-pty in-container. New pane type wires into the BooCode shell.
+**Status:** Planned. Largest batch in v1.1. Depends on Batch 3 (pane system), Batch 7 (settings drawer pattern reused).
+**Repo:** `/opt/boocode/` (shared monorepo). New `apps/booterm/` subdirectory.
+
+## Goals
+
+1. New container `booterm` running Fastify + node-pty + tmux. Per-session tmux session keyed by `(user, session_id)`.
+2. xterm.js terminal pane in the BooCode shell. Multiple terminal panes per session, each attached to a separate tmux window.
+3. PTY traffic over WebSocket. Auth via `Remote-User`.
+4. tmux as session manager so terminals survive WebSocket reconnects, page refreshes, even container restarts.
+5. Read+write capability scoped to project root. No `cd ..` escape.
+6. Path-based routing: `code.indifferentketchup.com/api/term/*` → booterm; `/ws/term/*` → booterm.
+
+## Architecture

+
+booterm container:
+  - Fastify (Node 20)
+  - node-pty
+  - tmux installed in container (apk add tmux)
+  - same Postgres (boocode_db)
+  - mounts projects rw (scoped)
+```
+
+### Mount strategy
+
+Decided: Option A. Per-project bind mounts in `docker-compose.yml`. Already applied: booterm has `/opt:/opt:rw` to keep parity with the existing boocode mount and avoid enumerating roots. Project root for any given session derives from `projects.root_path` and tmux launches with `cwd` set there.
+
+### tmux session naming
+
+Per-session tmux:
+
+```
+tmux session name: bc-<session_id>     (UUID, sanitized — alphanumeric + hyphen)
+tmux windows:      term-<pane_id>      (one window per terminal pane)
+```
+
+booterm spawns `tmux new-session -d -s bc-<sid> -c <project_root>` lazily on first attach. Subsequent attaches do `tmux new-window -t bc-<sid>` for additional panes, or `tmux attach -t bc-<sid>` and select window.
+
+## Data model
+
+| Column | On | Type | Default | Notes |
+|---|---|---|---|---|
+| (none) | — | — | — | terminals are tmux-managed, no DB rows |
+| `kind = 'terminal'` | `session_panes.kind` CHECK | — | — | Extend CHECK to include `'terminal'` |
+| `state.tmux_window` | `session_panes.state` JSONB | TEXT | NULL | Which tmux window this pane attaches to |
+
+Schema (already applied to live DB + schema.sql):
+
+```sql
+ALTER TABLE session_panes DROP CONSTRAINT IF EXISTS session_panes_kind_check;
+ALTER TABLE session_panes ADD CONSTRAINT session_panes_kind_check
+  CHECK (kind IN ('chat', 'file_browser', 'terminal'));

+server → client: {type: "exit", code} on window close
+```
+
+### Auth + scoping
+
+- `Remote-User` required on WS upgrade.
+- `session_id` validated: lookup in `sessions` table; require row exists.
+- `pane_id` validated: must exist in `session_panes` with `kind = 'terminal'` and matching `session_id`.
+- Project root derived from `sessions.project_id → projects.root_path`. tmux starts `cd <root>` in that dir. **No chroot.** User can `cd /` and read anything mounted into the container.
+  - Future hardening: namespace/chroot. Out of v1.1 scope.
+
+### tmux config
+
+`apps/booterm/tmux.conf` bundled into image at `/etc/booterm/tmux.conf`; tmux invocations use `-f /etc/booterm/tmux.conf`:
+
+```
+set -g default-terminal "screen-256color"
+set -g history-limit 50000
+set -g mouse on
+setw -g mode-keys vi
+set -g status off
+set -g destroy-unattached off
+```
+
+Boolab pattern (from `services/tmux_session.py`).
+
+## Frontend
+
+| File | Change |
+|---|---|
+| `apps/web/src/components/panes/TerminalPane.tsx` (NEW) | xterm.js mount, WS attach, resize handler |
+| `apps/web/src/api/client.ts` | `api.terminals.start(sessionId, paneId)`, `api.terminals.resize(...)`, `api.terminals.kill(...)` |
+| `apps/web/src/components/Workspace.tsx` | Add 'terminal' to the pane kind enum; spawn button → POST start → render TerminalPane. Tab UI lives in Workspace.tsx — there is no PaneTab.tsx file. |
+| `apps/web/package.json` | `xterm` + `xterm-addon-fit` + `xterm-addon-web-links` |
+
+### TerminalPane
+
+```tsx
+useEffect(() => {
+  const term = new Terminal({ fontFamily: 'JetBrains Mono', fontSize: 14, theme: ... });
+  const fit = new FitAddon();
+  term.loadAddon(fit);
+  term.loadAddon(new WebLinksAddon());
+  term.open(containerRef.current);
+  fit.fit();
+
+  const proto = window.location.protocol === 'https:' ? 'wss:' : 'ws:';
+  const ws = new WebSocket(`${proto}//${window.location.host}/ws/term/sessions/${sid}/panes/${pid}`);
+  ws.binaryType = 'arraybuffer';
+  ws.onmessage = e => term.write(typeof e.data === 'string' ? e.data : new Uint8Array(e.data));
+  term.onData(data => ws.send(data));
+  term.onResize(({ cols, rows }) => api.terminals.resize(sid, pid, cols, rows));
+
+  const ro = new ResizeObserver(() => fit.fit());
+  ro.observe(containerRef.current);
+
+  return () => { ws.close(); term.dispose(); ro.disconnect(); };
+}, [sid, pid]);
+```
+
+Dev: vite.config.ts needs `/api/term` and `/ws/term` proxy entries mirroring the existing `/api` and `/ws` ones.
+
+## Send-to-terminal from chat
+
+Boolab pattern: select text in a message → "Send to terminal" button → text becomes terminal input.
+
+- Right-click context menu on selected text in chat → "Send to terminal" submenu lists open terminal panes.
+- Click target → sends `<text>\n` to that pane's WS.
+
+Implementation:
+
+| File | Change |
+|---|---|
+| `apps/web/src/components/MessageBubble.tsx` | Selection handler + context menu |
+| `apps/web/src/lib/events.ts` | New event `send_to_terminal` with payload `{pane_id, text}` |
+| `apps/web/src/components/panes/TerminalPane.tsx` | Subscribe to event for its `pane_id`, write to WS |
+
+## Docker compose (already applied)
+
+booterm service is already in `docker-compose.yml` with:
+- build context `.`, dockerfile `apps/booterm/Dockerfile`
+- port `100.114.205.53:9501:3000`
+- `/opt:/opt:rw` mount
+- `DATABASE_URL` env pointing at `boocode_db`
+- `boocode_net` network
+- depends_on: `boocode_db`
+
+Do not re-edit compose.
+
+## Backend dependencies
+
+`apps/booterm/package.json`:
+- `fastify`
+- `@fastify/websocket`
+- `pg`
+- `zod`
+- `node-pty`
+- `tslib`
+
+`node-pty` requires native build. Dockerfile installs `python3 make g++` in build stage and `tmux` in runtime stage:
+
+```dockerfile
+FROM node:20-alpine AS build
+RUN apk add --no-cache python3 make g++ tmux
+WORKDIR /app
+COPY ...
+RUN pnpm install --frozen-lockfile && pnpm build
+
+FROM node:20-alpine
+RUN apk add --no-cache tmux

+COPY --from=build /app/apps/booterm/dist ./dist
+COPY --from=build /app/node_modules ./node_modules
+EXPOSE 3000
+CMD ["node", "dist/index.js"]
+```
+
+## Files to touch
+
+**New app:**
+
+- `apps/booterm/` (entire subtree)
+
+**Existing changes:**
+
+- `apps/web/package.json`
+- `apps/web/src/api/client.ts`
+- `apps/web/src/api/types.ts`
+- `apps/web/src/components/Workspace.tsx`
+- `apps/web/src/components/MessageBubble.tsx`
+- `apps/web/src/components/panes/TerminalPane.tsx` (NEW)
+- `apps/web/src/lib/events.ts`
+- `apps/web/vite.config.ts` (proxy entries)
+
+**Already done by user — do not touch:**
+
+- `docker-compose.yml` (booterm service added)
+- `apps/server/src/schema.sql` (terminal CHECK constraint)
+- Live DB constraint applied
+
+## Verification
+
+1. `docker compose up -d --build booterm` → container healthy.
+2. `curl -s http://100.114.205.53:9501/api/term/health -H 'Remote-User: sam'` → 200.
+3. Browser smoke test:
+   - Open a session. Workspace → "+ Terminal" → terminal pane appears with shell prompt in project root.
+   - Type `ls -la` → output.
+   - Type `vim test.txt`, write something, save, `:q` → file exists on host (since rw mount).
+   - Refresh browser → terminal reconnects, history intact (tmux persistence).
+   - Open second terminal pane → same project, separate tmux window. Both work independently.
+   - Select code in chat → right-click → "Send to terminal" → terminal pane receives the text.
+   - Container restart (`docker compose restart booterm`) → on reconnect, tmux session resumes from where it left off.
+   - Close pane via tab context menu → tmux window killed. Reopen pane → fresh shell.
+
+## Constraints
+
+- node-pty is a native dep. Image size grows.
+- tmux history capped at 50k lines per window.
+- WebSocket frames are bidirectional binary; `binaryType = 'arraybuffer'`.
+- Resize debounced 100ms client-side; backend `tmux resize-window` per resize.
+- No chroot/namespace isolation in v1.1. User has full read+write under `/opt/`. Acceptable for single-user homelab.
+- Don't expose 9501 on 0.0.0.0. Tailscale binding only (already configured in compose).
+
+## Open
+
+- Color theme matching for xterm.js. Defer.
+- File-drop into terminal (upload via terminal pane). Out of scope.
+- Multi-user (each user gets own tmux server) — defer until BooCode goes multi-user, which isn't planned.
+- BooCoder container — same skeleton as booterm but with edit_file / create_file tools instead of PTY. Will follow this pattern when built.
