Nico 1000411eb2 v0.15.0: Frame engine (v3), PA + Expert architecture (v4-eras), live test streaming
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

# Fast v4
10 quick checks for v4-eras: PA routing, expert DB queries, progress streaming.
## Setup
- clear history
## Steps
### 1. Reflex
- send: hi!
- expect_response: length > 2
### 2. PA routes to expert
- send: show me 3 customers
- expect_trace: has routed
- expect_trace: has tool_call
- expect_response: length > 10
### 3. German query
- send: Zeig mir alle Tabellen in der Datenbank
- expect_trace: has tool_call
- expect_response: length > 10
### 4. Schema discovery
- send: describe the kunden table
- expect_trace: has tool_call
- expect_response: length > 10
### 5. Count query (cached schema)
- send: how many customers are there?
- expect_trace: has tool_call
- expect_response: length > 5
### 6. Complex query
- send: which customers have the most devices?
- expect_trace: has tool_call
- expect_response: length > 20
### 7. Error recovery
- send: SELECT * FROM nichtexistiert
- expect_trace: has tool_call
- expect_response: length > 10
### 8. Memorizer
- send: my name is Nico
- expect_state: facts any contains "Nico"
### 9. Language switch
- send: Hallo wie gehts?
- expect_state: language is "de" or "mixed"
### 10. Bye
- send: ok bye
- expect_response: length > 2
