Complete rewrite of the terminal pipeline for VS Code Server-level responsiveness. Key improvements: Backend: - Replace blocking select.select(0.1) with asyncio.add_reader() for event-driven PTY reading (eliminates ~110ms polling latency) - Add output batching (2ms window) to reduce WebSocket frame overhead - Add flow control: client acks processed bytes, server pauses PTY reads at 64KB threshold, resumes at 32KB - Add 5s ack timeout fallback to prevent stuck sessions Frontend: - Switch WebSocket to binary mode (binaryType = 'arraybuffer') - Eliminate Blob -> arrayBuffer async conversion overhead - Add flow control ack messages (every 4096 bytes or 100ms) - Add xterm-addon-webgl with graceful DOM fallback - Add performance tuning (scrollback=10000, fastScrollSensitivity) SDD artifacts: - openspec/explorations/terminal-responsiveness.md - openspec/proposals/terminal-responsiveness.md - openspec/specs/terminal-responsiveness.md - openspec/designs/terminal-responsiveness.md - openspec/tasks/terminal-responsiveness.md Quality gates: pytest (19 passed, 1 skipped), tsc --noEmit clean
