Gate (tht-gate.js):
- Pre-validate decision types against workflow.yaml before showing reviewer widget
- Reject decisions emitted by later phases (min-phase check)
- Copy top-level `kind` into artifact when model forgets it (prevents loop)
- Force-advance on reviewer_decide/schema_linking when advance:true — skip
redundant reviewer_confirm gate
Backend:
- Emit agent_end on clean Pi exit (code 0 + bridge idle) instead of marking failed
Frontend:
- Strip <think> tags from transcript and activity panel
- Fix mermaid render with offscreen container + cleanup
- Graceful mermaid error: show source code instead of red error, fall back to table
Workflow:
- F2 now emits table_promoted and table_excluded (early schema linking decisions)
