Frame Engine (v3-framed):
- Tick-based deterministic pipeline: frames advance on completion, not timers
- FrameRecord/FrameTrace dataclasses for structured per-message tracing
- /api/frames endpoint: queryable frame trace history (last 20 messages)
- frame_trace HUD event with full pipeline visibility
- Reflex=2F, Director=4F, Director+Interpreter=5F deterministic frame counts
Expert Architecture (v4-eras):
- PA node (pa_v1): routes to domain experts, holds user context
- ExpertNode base: stateless executor with plan+execute two-LLM-call pattern
- ErasExpertNode: eras2_production DB specialist with DESCRIBE-first discipline
- Schema caching: DESCRIBE results reused across queries within session
- Progress streaming: PA streams thinking message, expert streams per-tool progress
- PARouting type for structured routing decisions
UI Controls Split:
- Separate thinker_controls from machine controls (current_controls is now a property)
- Machine buttons persist across Thinker responses
- Machine state parser handles both dict and list formats from Director
- Normalized button format with go/payload field mapping
WebSocket Architecture:
- /ws/test: dedicated debug socket for test runner progress
- /ws/trace: dedicated debug socket for HUD/frame trace events
- /ws (chat): cleaned up, only deltas/controls/done/cleared
- WS survives graph switch (re-attaches to new runtime)
- Pipeline result reset on clear
Test Infrastructure:
- Live test streaming: on_result callback fires per check during execution
- Frontend polling fallback (500ms) for proxy-buffered WS
- frame_trace-first trace assertion (fixes stale perceived event bug)
- action_match supports "or" patterns and multi-pattern matching
- Trace window increased to 40 events
- Graph-agnostic assertions (has X or Y)
Test Suites:
- smoketest.md: 12 steps covering all categories (~2min)
- fast.md: 10 quick checks (~1min)
- fast_v4.md: 10 v4-eras specific checks
- expert_eras.md: eras domain tests (routing, DB, schema, errors)
- expert_progress.md: progress streaming tests
Other:
- Shared db.py extracted from thinker_v2 (reused by experts)
- InputNode prompt: few-shot examples, history as context summary
- Director prompt: full tool signatures for add_state/reset_machine/destroy_machine
- nginx no-cache headers for static files during development
- Cache-busted static file references
Scores: v3 smoketest 39/40, v4-eras fast 28/28, expert_eras 23/23

- 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

RED->GREEN->REFACTOR cycle:
- UI node has state store (key-value), action bindings (op/var), and
local action handlers (inc/dec/set/toggle — no LLM round-trip)
- Thinker self-model: knows its environment, that ACTIONS create real
buttons, that UI handles state locally. Emits var/op payload for
stateful actions.
- Thinker's context includes UI state so it can report current values
- /api/clear resets UI state, bindings, and controls
- Test runner: action_match for fuzzy action names, persistent actions
across steps, _stream_text restored
- Counter test: 16/16 passed (create, read, inc, inc, dec, verify)
- Pub test: 20/20 passed (conversation, language switch, tool use, mood)

- testcases/*.md: declarative test definitions (send, expect_response,
expect_state, expect_actions, action)
- runtime_test.py: standalone runner + pytest integration via conftest.py
- /tests route: web UI showing last run results from results.json
- /api/tests: serves results JSON
- Two initial testcases: counter_state (UI actions) and pub_conversation
(multi-turn, language switch, tool use, memorizer state)
- pub_conversation: 19/20 passed on first run
- Fix nm-text vertical overflow in node metrics bar
