The Trajectory Cannot Hide
SSM State · Trajectory Hash · Every Step Chained
State Space Models maintain persistent hidden memory that evolves across every token. PHM enforces the trajectory. WitnessBound chains every state transition into a cryptographic fingerprint — the trajectory hash — that proves the full path, not just the terminal action.
SSM Trajectory Receipt
Every Step Witnessed.
The Full Path Proven.
When PHM detects emergent drift in an SSM hidden state, WitnessBound generates a trajectory receipt containing the cryptographic hash of every state transition that led to the violation.
