TrackChain Master Synchronization & Multi-Modal Fusion Contract Verifier (tc.v1 SOTA).
Verifies:
1. All 5 Phase 2 models instantiate and execute forward inference cleanly on device.
2. All 5 calibration manifests are valid and map to the unified [0.0, 1.0] probability space.
3. Universal 0.50 decision boundary is strictly respected.
4. Multi-modal cross-attention / compound defect fusion contracts hold.
