Scope & Acceptance Criteria -- [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).

Edge cases & failure paths (from `verification/edge-cases.md`) -- 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`. +- Platform without `statfs` or restricted disk permission: disk metrics return null/fallback; UI gracefully renders "N/A" instead of crashing. +- CPU calculation delta: handles initial sample or multi-core distribution without returning NaN or negative numbers. +- Connection loss during polling: stops polling / flags data as stale; resumes automatically upon reconnection. +- Zero battery drain: polling timer cleaned up when unmounted. ## 3. E2E scenario(s) -1. 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. +1. Agent daemon starts with sysinfo provider. +2. Mobile client connects -> requests telemetry -> receives `sys.metrics` frame. +3. Mobile tiles render live CPU, RAM, and Disk values with valid percentages. +4. Connection disconnects -> tiles display "Disconnected / Stale". ## 4. Plan (thinnest vertical slice) -1. Create `packages/mobile/src/terminal/buffer.ts` (ANSI parser & scrollback buffer state machine). -2. Write unit tests in `packages/mobile/src/terminal/buffer.test.ts`. -3. Add terminal methods to `AgentClient` in `packages/mobile/src/client.ts`. -4. Create React components: `AccessoryBar.tsx`, `HistoryModal.tsx`, `TerminalScreen.tsx`, and wire in `App.tsx`. -5. Add integration tests in `packages/mobile/src/mobile.test.ts`. -6. Run full verification (`pnpm verify`), capture evidence, and open PR. +1. Protocol schemas in `@shellmind/protocol/src/messages/sysinfo.ts` and registry. +2. Core interface and adapter in `packages/agent/src/core/sysinfo.ts` and `src/adapters/sysinfo/node-sysinfo.ts`. +3.
