Keep the terminal view modular: The protocol layer (`term.open`, `term.data`, `term.input`, `term.resize`, `term.exit`) remains completely decoupled from the rendering engine.

Scope & Acceptance Criteria -- [x] Wire protocol messages in `@shellmind/protocol`: - - `term.open`: request to open a new PTY session with initial dimensions (`cols`, `rows`), optional `cwd`, and optional `env`. - - `term.input`: client keystroke / stdin transmission. - - `term.data`: server PTY stdout/stderr chunk streaming to client. - - `term.resize`: client viewport resize event (`cols`, `rows`). - - `term.exit`: server PTY process termination notification (`exitCode`, `signal`). -- [x] Protocol schemas added to `MessageRegistry` and codec `KnownMessage` union with 100% round-trip unit test coverage. -- [x] Pure core terminal interfaces in `packages/agent/src/core/terminal.ts` (`ITerminalSession`, `ITerminalManager`). -- [x] Concrete adapter implemented in `packages/agent/src/adapters/pty/node-pty.ts` using `node-pty`: - - Auto-detection and executable permission fix (`0755`) for macOS/Linux `spawn-helper`. - - Clean child process lifecycle management and signal forwarding. -- [x] Agent daemon message dispatch in `packages/agent/src/core/daemon.ts`: - - Handles `term.open`, `term.input`, `term.resize`. - - Automated teardown: kills child PTY processes immediately when client socket disconnects or agent daemon stops (no orphan processes). -- [x] Architecture boundary: pure core in `src/core/` does not import `node-pty` or OS builtins; `check-architecture.sh` passes with 0 violations. -- [x] Full integration tests in `packages/agent/src/agent.test.ts` verifying real PTY spawn, stdout streaming, stdin command execution, resize, exit code reporting, and orphan cleanup on disconnect. +- [x] ADR-0002 recorded: Native React Native ANSI Stream Buffer vs xterm.js in WebView. +- [x] Pure TypeScript terminal buffer (`TerminalBuffer` in `packages/mobile/src/terminal/buffer.ts`): + - Ingests streaming `term.data` text chunks. + - Parses ANSI color codes (SGR standard & bright foregrounds/backgrounds, bold, dim, underline, inverse, reset). + - Handles terminal control characters (`\r`, `\n`, `\b`, `\x1b[2K`, `\x1b[K`). + - Implements scrollback line buffer with configurable line limit (e.g. 2000 lines). + - Produces structured line spans for rendering. +- [x] Mobile-native accessory keyboard row: + - Quick action keys: `Ctrl`, `Esc`, `Tab`, `↑`, `↓`, `←`, `→`, `|`, `/`, `-`, `~`. + - When `Ctrl` modifier is active, typing a character generates control code (e.g. `Ctrl+C` -> `\x03`, `Ctrl+D` -> `\x04`, `Ctrl+Z` -> `\x1a`). +- [x] Command history buffer: + - Stores executed input commands. + - Up / Down arrow navigation cycles through previous commands. + - History drawer / list for tap-to-rerun. +- [x] Terminal UI (`TerminalScreen.tsx`): + - Monospace font, dark high-contrast terminal theme. + - Autoscroll on new output with scrollback inspection. + - Window resize trigger (`term.resize`) calculated on orientation / viewport change. + - Disconnect banner preserving terminal output without freezing UI. +- [x] Client integration in `AgentClient`: + - Terminal session management (`openTerminal`, `sendTerminalInput`, `resizeTerminal`). + - Terminal event listeners (`onTerminalData`, `onTerminalExit`). +- [x] Comprehensive unit and integration tests in `packages/mobile/src/terminal/buffer.test.ts` and `packages/mobile/src/mobile.test.ts`. +- [x] Clean architecture (`check-architecture.sh` 0 violations). Full verify (`pnpm verify`) green. ## 2. Edge cases & failure paths (from `verification/edge-cases.md`) -- `node-pty` macOS prebuild permission issue: `spawn-helper` extracted with mode `0644`. Resolved via `ensureSpawnHelperExecutable` before spawn and `scripts/init.sh`. -- Client disconnects while command is executing: daemon catches socket `close`, immediately invokes `term.kill()`, removing from active sessions and preventing zombie / orphan processes. -- Process exits naturally: `session.onExit` event broadcasts `term.exit` frame and cleans up session registry. -- Client attempts multiple `term.open` on the same session: existing PTY is safely terminated and replaced. +- Rapid / large output chunks (thousands of lines): buffer trims scrollback cleanly without OOM or lag. +- ANSI color sequences split across chunks: buffer maintains parser state. +- Carriage returns (`\r`) overwriting lines (e.g. download progress bars `[==> ] 20%` -> `[====> ] 40%`). +- Disconnect mid-session: UI displays disconnected banner, disables input, but retains full scrollback history. +- Rapid typing and control character key combinations (`Ctrl+C` sends interrupt `\x03`). +- Window resize: calculates reasonable cols/rows and sends `term.resize`. ## 3. E2E scenario(s) -Integration tests in `packages/agent/src/agent.test.ts`: -1. Authenticate client -> `term.open` -> verify initial shell prompt received via `term.data`. -2.

Client connects -> opens terminal session -> receives banner and prompt via `term.data`. +2. User enters command (`pwd`) -> receives streamed output -> command added to history. +3. User presses `↑` accessory key -> recalls previous command (`pwd`). +4. User taps `Ctrl` + `C` -> sends `\x03` interrupt signal. +5. Resize viewport -> sends `term.resize` with updated dimensions. +6. Connection drops -> status banner shows Offline, scrollback remains visible and interactive. ## 4.

Core interfaces (`ITerminalSession`, `ITerminalManager`) in `packages/agent/src/core/terminal.ts`. -3.
