- Wire Interpreter into v2 pipeline (after Thinker tool_output, before Output)
- Rename tool_exec -> tool_call everywhere (consistent convention across v1/v2)
- Switch Director v1+v2 to anthropic/claude-haiku-4.5 (was opus, reserved)
- Fix UI apply_machine_ops crash when states are strings instead of dicts
- Fix runtime_test.py async poll to match on message ID (prevent stale results)
- Add traceback to pipeline error logging

- OutputSink: collects output, optionally streams to attached WS
- Runtime no longer requires WebSocket — works headless for MCP
- WS connects/disconnects via attach_ws()/detach_ws(), runtime persists
- /api/send/check + /api/send (async) + /api/result (poll with progress)
- Graph switch destroys old runtime, next request creates new one
- Director v2 model: claude-opus-4 (was claude-sonnet-4, reserved)
