Same-bag proof protocol
One identity, continuously verified
The chain is trusted only when credentials, physical DNA, route, seal, handler, and custody sequence continue to agree.

Trust Graph impact
Current trust score is 100. Score changed because positive evidence (RFID match +8: Issued RFID was observed.; NFC match +8: Secure NFC token matched.; QR valid +4: Rotating QR token is valid.; Visual DNA +10: Visual profile matches check-in capture.; Weight tolerance +6: Weight stayed within tolerance.; Seal status +8: Seal remained intact.; Route consistency +4: Route agrees with manifest.; Custody continuity +8: No custody blackout detected.) was weighed against negative evidence (Weather pressure -4: Weather pressure can weaken operational certainty.).
Threat Graph impact
No evidence
Identity Confidence explanation
Original bag verified. Positive signals: RFID match +8, NFC match +8, QR valid +4, Visual DNA above 96% +10, Weight within tolerance +6, Dimensions match +4, Seal intact +8, Route consistent +4, Custody continuity +8. Negative signals: none.
Integrity Score explanation
Verified: RFID match increased trust; NFC cryptographic token matched; QR token is valid. Weather pressure reduced custody confidence by 4 points
