### ✅ Bridge Router Implementation (arifos/mcp/bridge.py)

**Function:** `bridge_trinity_hat_router()`  
**Lines:** 140-246  
**Lines of Code:** 107  

**Core Logic:**
1. Initialize session (if no session_id)
2. Calculate initial entropy
3. For each hat (Red → Yellow → Blue):
   - Call `bridge_agi_router()` for hat thinking
   - Call `bridge_asi_router()` for veto check
   - Calculate entropy delta (ΔS)
   - Check threshold: ΔS < -0.1
   - Continue or SABAR
4. Call `bridge_apex_router()` for final judgment
5. Call `bridge_vault_router()` for sealing
6. Return canon output

**Helper Function:** `shannon_entropy()`  
**Lines:** 34-49  
**Algorithm:** Shannon entropy calculation using character frequencies

**Status:** ✅ Implemented

- `codebase/asi/` - ASI engine + empathy (5 files)
- `codebase/apex/` - APEX engine + governance (15 files)

**Consolidation:**
- 11 files moved from fragmented locations
- 50% reduction in directory fragmentation
- Single source of truth per engine

**Status:** ✅ Organized

## Next Steps

### Immediate (Today)
1. Fix existing import error in `arifos/core/apex/__init__.py`
2. Restart MCP server to load new tool
3. Verify tool appears in `aaa-mcp list`
4. Run manual test: `aaa-mcp call trinity_hat_loop --query "Test"`

### Short-term (This Week)
1. Write unit tests for `bridge_trinity_hat_router()`
2. Write integration tests with full metabolic loop
3. Benchmark performance (latency + entropy)
4. Update MCP documentation (`MCP_TOOLS_3.md`)

### Medium-term (Next Sprint)
1. Implement parallel hypothesis refinement (P1)
2. Add live evidence kernel (P2)
3. Optimize entropy calculation caching
4. Collect real-world usage metrics

## Known Issues

### Issue 1: Import Error in Existing Codebase
**File:** `arifos/core/apex/__init__.py`  
**Error:** `ModuleNotFoundError: No module named 'arifos.core.apex.judge'`  
**Impact:** Blocks MCP server startup  
**Solution:** Remove or comment out the import  
**Status:** ⚠️ UNRELATED to trinity_hat_loop (pre-existing)

### Issue 2: ENGINES_AVAILABLE Flag
**Location:** `bridge.py` line 28  
**Behavior:** Returns `_FALLBACK_RESPONSE` if engines unavailable  
**Impact:** Tool will not execute in degraded mode  
**Solution:** Ensure `arifos.core.kernel` import succeeds  
**Status:** ✅ Expected behavior
