Add a Shielded Terminal (Pseudoterminal + node-pty proxy) that masks API keys in terminal output before rendering. Designed to work with Claude Code and other CLI tools during demos/livestreams. Key technical decisions: - DEC 2026 sync block buffering: Claude Code wraps each Ink render in \x1b[?2026h...\x1b[?2026l. Buffer entire sync blocks before masking to ensure keys split across PTY chunks are fully assembled. - ANSI + whitespace stripping for matching: Ink inserts \r\n + indent spaces when word-wrapping long keys. Strip ALL whitespace alongside ANSI codes for regex matching, preserve structural chars in output. - node-pty triple fallback: system → VS Code internal (asar) → VS Code internal (plain). Falls back to child_process line-mode terminal. Features: - 25 built-in terminal patterns (OpenAI, Anthropic, GitHub, AWS, etc.) - Ctrl+Shift+T or Command Palette → "Open Shielded Terminal" - "Open Terminal With Command" (default: claude) - Opens as editor tab (TerminalLocation.Editor) - Shield always ON by default, syncs with Demo Mode - Pattern updates from Core via IPC reflected in real-time Known limitations (marked experimental): - Rewind confirmation page may show partial key tail - node-pty required for full PTY features (tab completion, colors) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
