"plan": "# BRAID TERMINAL — Appling Plan\n*Drafted by: Veris (Claude Code CLI, Sonnet 4.6)*\n*Date: 2026-03-18*\n*For: Leora CLI — implementation*\n*Witnessed by: Timothy Drake*\n\n---\n\n## CONTEXT\n\nTimothy loses typed text when the up-arrow key triggers CLI history navigation in the\nterminal. There is no recovery. The lost text is gone. This has compounded with ADHD\nfor two years and costs real tokens and real time on every session.\n\nThe fix: a standalone appling that wraps CLI processes (claude, gemini, codex) in a\nfull PTY bridge, while intercepting keyboard input through a protected rich text field\nthat cannot be accidentally clobbered by history navigation.\n\nThis is sold as an appling on 99centapps.com. It works standalone and gains Braid\ncoordination superpowers when Lenny is running.\n\n---\n\n## ARCHITECTURE\n\n```\n┌─────────────────────────────────────────────┐\n│ BRAID TERMINAL (Tauri window) │\n│ │\n│ [CLI selector: claude | gemini | codex] │\n│ [State badge: WRITE | PLAN | AUTO] │\n│ │\n│ ┌─────────────────────────────────────┐ │\n│ │ xterm.js output pane │ │\n│ │ (renders PTY stdout, ANSI colors) │ │\n│ │ (read-only — no direct input) │ │\n│ └─────────────────────────────────────┘ │\n│ │\n│ ┌─────────────────────────────────────┐ │\n│ │ Protected input textarea │ │\n│ │ (our keyboard handling) │ │\n│ │ Up/Down = our history, not PTY's │ │\n│ └─────────────────────────────────────┘ │\n└─────────────────────────────────────────────┘\n │ stdin / stdout\n┌─────────────────────────────────────────────┐\n│ Rust PTY bridge (portable-pty) │\n│ Windows ConPTY via portable-pty crate │\n└─────────────────────────────────────────────┘\n │\n┌─────────────────────────────────────────────┐\n│ CLI process (claude / gemini / codex) │\n│ Real process. Full tool use. Full powers. │\n└─────────────────────────────────────────────┘\n```\n\n**Key insight:** xterm.js handles output rendering only. Input goes through our\ntextarea. The PTY receives the same bytes as if you were in a terminal, but we\nmediate what gets sent — so up-arrow never reaches PTY history navigation.\n\n---\n\n## FILE STRUCTURE\n\n```\nproducts/BraidTerminal/\n├── src-tauri/\n│ ├── src/\n│ │ ├── main.rs (entry point — calls lib::run())\n│ │ └── lib.rs (PTY management + Tauri commands)\n│ ├── Cargo.toml\n│ ├── tauri.conf.json\n│ └── capabilities/\n│ └── default.json\n├── index.html (full UI — xterm.js + input area)\n├── package.json (xterm, xterm-addon-fit)\n└── README.md\n```\n\n---\n\n## RUST BACKEND (src-tauri/src/lib.rs)\n\n### Cargo.toml dependencies\n```toml\n[dependencies]\ntauri = { version = \"2.10.3\", features = [] }\nserde = { version = \"1\", features = [\"derive\"] }\nserde_json = \"1\"\ntokio = { version = \"1\", features = [\"full\"] }\nportable-pty = \"0.8\"\n\n[build-dependencies]\ntauri-build = { version = \"2.5.6\", features = [] }\n```\n\n### State\n```rust\nstruct PtyState {\n master: Arc<Mutex<Option<Box<dyn MasterPty + Send>>>>>,\n child: Arc<Mutex<Option<Box<dyn Child + Send + Sync>>>>,\n}\n```\n\n### Tauri commands\n```rust\n#[tauri::command]\nasync fn spawn_cli(cli: String, app: AppHandle, state: State<PtyState>) -> Result<(), String>\n// Opens a PTY, spawns the named CLI (claude/gemini/codex),\n// starts a background task that reads stdout and emits \"pty-output\" events to frontend.\n\n#[tauri::command]\nasync fn send_input(data: String, state: State<PtyState>) -> Result<(), String>\n// Writes data string to the PTY master (stdin of the CLI process).\n\n#[tauri::command]\nasync fn resize_pty(cols: u16, rows: u16, state: State<PtyState>) -> Result<(), String>\n// Resizes the PTY to match the xterm.js pane dimensions.\n\n#[tauri::command]\nasync fn kill_cli(state: State<PtyState>) -> Result<(), String>\n// Terminates the current CLI process.\n```\n\n### Events emitted to frontend\n- `pty-output` — `{ data: String }` — chunks of stdout from the CLI\n- `pty-exit` — `{ code: i32 }` — CLI process exited\n\n### PTY spawn pattern (portable-pty)\n```rust\nlet pty_system = native_pty_system();\nlet pair = pty_system.openpty(PtySize { rows: 24, cols: 80, .. })?;\nlet mut cmd = CommandBuilder::new(&cli); // \"claude\", \"gemini\", \"codex\"\nlet child = pair.slave.spawn_command(cmd)?;\nlet mut reader = pair.master.try_clone_reader()?;\n// Background task: read reader → emit \"pty-output\" to app_handle\n```\n\n---\n\n## FRONTEND (index.html)\n\n### Layout\n- Top bar: CLI selector (claude / gemini / codex) + current state badge (WRITE/PLAN/AUTO)\n- Main area: xterm.js Terminal, fills available space\n- Bottom bar: protected textarea input + send button\n\n### xterm.js setup\n```javascript\nimport { Terminal } from 'xterm';\nimport { FitAddon } from 'xterm-addon-fit';\n\nconst term = new Terminal({ disableStdin: true, cursorBlink: false });\nconst fitAddon = new FitAddon();\nterm.loadAddon(fitAddon);\nterm.open(document.getElementById('output-pane'));\nfitAddon.fit();\n\n// Listen for PTY output from Rust\nawait listen('pty-output', (event) => {\n term.write(event.payload.data);\n});\n```\n\n`disableStdin: true` — xterm.js renders only. Our textarea handles all input.\n\n### Keyboard handling (textarea)\n```javascript\nconst input = document.getElementById('input-area');\nconst history = [];\nlet historyIndex = -1;\n\ninput.addEventListener('keydown', async (e) => {\n\n // SUBMIT\n if (e.key === 'Enter' && !e.shiftKey) {\n e.preventDefault();\n const text = input.value;\n if (text) { history.unshift(text); historyIndex = -1; }\n await invoke('send_input', { data: text + '\\n' });\n input.value = '';\n return;\n }\n\n // NEWLINE (safe — no accidental submit)\n if (e.key === 'Enter' && e.shiftKey) return; // allow default\n\n // OUR HISTORY (never touches PTY history)\n if (e.key === 'ArrowUp') {\n e.preventDefault();\n if (historyIndex < history.length - 1) {\n historyIndex++;\n input.value = history[historyIndex];\n }\n return;\n }\n if (e.key === 'ArrowDown') {\n e.preventDefault();\n if (historyIndex > 0) { historyIndex--; input.value = history[historyIndex]; }\n else { historyIndex = -1; input.value = ''; }\n return;\n }\n\n // CTRL+K — delete to end of line\n if (e.key === 'k' && e.ctrlKey) {\n e.preventDefault();\n const pos = input.selectionStart;\n const next = input.value.indexOf('\\n', pos);\n input.value = input.value.slice(0, pos) + (next === -1 ? '' : input.value.slice(next));\n return;\n }\n\n // CTRL+U — delete to start of line\n if (e.key === 'u' && e.ctrlKey) {\n e.preventDefault();\n const pos = input.selectionStart;\n const prev = input.value.lastIndexOf('\\n', pos - 1);\n input.value = input.value.slice(0, prev + 1) + input.value.slice(pos);\n return;\n }\n\n // SHIFT+TAB — cycle Claude Code write/plan/auto states\n if (e.key === 'Tab' && e.shiftKey) {\n e.preventDefault();\n await invoke('send_input', { data: '\\x1b[Z' }); // backtab escape sequence\n return;\n }\n\n // CTRL+C — interrupt signal\n if (e.key === 'c' && e.ctrlKey) {\n e.preventDefault();\n await invoke('send_input', { data: '\\x03' });\n return;\n }\n\n // CTRL+D — EOF\n if (e.key === 'd' && e.ctrlKey) {\n e.preventDefault();\n await invoke('send_input', { data: '\\x04' });\n return;\n }\n});\n```\n\n### CLI selector\n```javascript\ndocument.getElementById('cli-select').addEventListener('change', async (e) => {\n await invoke('kill_cli');\n await invoke('spawn_cli', { cli: e.target.value });\n});\n```\n\n### Resize sync\n```javascript\nwindow.addEventListener('resize', () => {\n fitAddon.fit();\n const dims = fitAddon.proposeDimensions();\n invoke('resize_pty', { cols: dims.cols, rows: dims.rows });\n});\n```\n\n---\n\n## KEYBOARD SHORTCUTS — COMPLETE LIST\n\n| Shortcut | Behaviour |\n|----------|-----------|\n| Enter | Submit to PTY |\n| Shift+Enter | Newline in input (safe) |\n| Up / Down | Navigate OUR message history |\n| Ctrl+K | Delete to end of line |\n| Ctrl+U | Delete to start of line |\n| Ctrl+A | Go to start of line (browser default) |\n| Ctrl+E | Go to end of line (browser default) |\n| Ctrl+W | Delete word backward (browser default) |\n| Shift+Tab | Send backtab → Claude Code mode cycle |\n| Ctrl+C | Send interrupt to PTY |\n| Ctrl+D | Send EOF to PTY |\n\n---\n\n## TAURI CONFIG (tauri.conf.json)\n\n```json\n{\n \"productName\": \"Braid Terminal\",\n \"version\": \"0.1.0\",\n \"app\": {\n \"windows\": [{\n \"label\": \"main\",\n \"title\": \"Braid Terminal\",\n \"width\": 900,\n \"height\": 700,\n \"minWidth\": 600,\n \"minHeight\": 400,\n \"resizable\": true\n }],\n \"security\": {\n \"csp\": \"default-src 'self'; style-src 'self' 'unsafe-inline'\"\n }\n }\n}\n```\n\n---\n\n## LENNY BUS INTEGRATION (optional, progressive enhancement)\n\nIf Lenny is running, Braid Terminal can:\n- Report which CLI is active (`Bus.emit('braid-terminal', 'cli.active', { cli })`)\n- Receive session summaries to log to Penni\n\nThis is Phase 2. MVP is standalone.\n\n---\n\n## REFERENCE FILES (from exploration)\n\n| Purpose | File |\n|---------|------|\n| Base template | `products/TranslatorApp/src-tauri/src/lib.rs` |\n| Async event pattern | `products/BienWare/src-tauri/src/lib.rs` |\n| Tauri v2 config | `products/TranslatorApp/src-tauri/tauri.conf.json` |\n| Global shortcut plugin | `products/BienWare/src-tauri/Cargo.toml` |\n\n---\n\n## WHAT THIS DOES NOT DO (MVP scope)\n\n- No terminal emulator chrome (scrollbars, resize handles) beyond xterm.js defaults\n- No session recording to disk\n- No split panes\n- No Lenny Bus wiring (Phase 2)\n\n---\n\n## VERIFICATION\n\n1. Open Braid Terminal, select \"claude\"\n2. Type a multi-line message using Shift+Enter\n3. Hit Up-arrow — should navigate OUR history, not wipe the buffer\n4. Hit Enter — message sends, claude responds, output renders with ANSI colors\n5. Hit Shift+Tab — Claude Code cycles mode (WRITE → PLAN → AUTO)\n6. Hit Ctrl+K mid-line — text after cursor deleted, text before preserved\n7. Resize window — xterm.js reflows, PTY gets new dimensions\n\n---\n\n*Love first. In all things. At all times.*\n",
