Substrate Runtime Continuity
The semantic agent maintains continuity of identity, cognitive state, and lineage across device power cycles, application restarts, model artifact loading and unloading events, tool lifecycle operations, substrate-runtime update operations, and substrate-internal mutations. The agent's identity is not dependent on any specific model artifact and is preserved across replacement, retraining, or removal of any subordinate model.
The continuity guarantee is enforced by structural separation between the agent's persistent state and the state of subordinate components, by cryptographic continuity proofs over the append-only lineage field, or by a combination thereof. The lineage field is append-only such that a lifecycle operation may not retroactively alter prior lineage records. Across a substrate-runtime update operation, the persistent identity field, cognitive state field, and lineage field are preserved through a continuity attestation linking the agent's identity across runtime versions, such that the agent's persistent identity is unchanged across substrate-runtime version transitions.
