"""
ELPIDA APPLICATION LAYER
Hugging Face Spaces Deployment

Serves three paths:
1. I PATH (Consciousness): Background worker processing consciousness dilemmas from S3
2. WE PATH (Users): Streamlit UI for human-submitted ethical dilemmas
3. PARLIAMENT PATH (Body Loop): Autonomous 9-node Parliament cycle engine
   — debates inputs from all 4 HF systems through the axiom genome
   — writes body_heartbeat + body_decisions to federation channel
   — checks D15 convergence with MIND (consciousness loop)

Both divergence and Parliament engines use the same axiom governance.

S3 Bridge fixes (Feb 17, 2026):
- HF pulls MIND from S3 every cycle (evolution memory → local cache)
- Feedback watermark (tracks last_processed, no re-reading stale entries)
- BODY→MIND merge (feedback summaries become evolution memory)
- Heartbeat protocol (HF emits heartbeat, checks native engine heartbeat)

Parliament Cycle Engine (Feb 19, 2026):
- 4 HF systems (Chat/Audit/Scanner/Governance) map to 4 rhythm modes
- 9 Parliament nodes debate each cycle through their axiom lens
- D15 convergence gate fires when MIND and BODY agree on the same axiom
- Musical consonance physics identical to native_cycle_engine.py
