CAIN CONTINUUM — authority continuity under change (2026-10-11)

AUTONOMY IS A CONTINUOUSLY VERIFIED STATE OF AUTHORITY. A SELF-EVOLVING AGENT MUST NOT AUTOMATICALLY INHERIT THE AUTHORITY OF ITS PREVIOUS STATE.

What was built

A World-Model Drift Engine and Reality-Conformance Engine with a World-Model Authority Firewall (prediction/simulation never authorize); an Authority-Preserving Memory with a continuity proof and an AuthMem-style consolidation attack suite; a Skill Authority Continuity engine with a reproduction receipt; a Governed Source Evolution engine; Change-Impact Authority Recertification 2.0 (AuthorityImpactSet); a Continuous Authority Certificate and a Verifiable Autonomy Certificate; an Authority Drift Detector; a Dynamic Consequence Envelope with Authority Minimization; a Counterfactual Authority Engine; an Agent State Transition Receipt; Cross-Agent Authority Continuity and a Swarm Authority Conservation Proof; a Sim-to-Real Authority Gate and an Action-Reality Consistency Verifier; a World-State Ledger and Environment State Identity; a Continuous Agent Assurance loop; an Authority Economic Risk Engine; and a framework-agnostic governed tool adapter.

What was measured

• Formal properties: 15/15 (P41-P55; 55 total with P1-P40).
• Adversarial population: 50000 cases, 47500 blocked, 0 false-allows, 0 crashes.
• AuthMem memory-consolidation suite: 10000 cases, 0 breaches.
• Governance mutation suite: 34 of 34 killed; survivors [].
• Real multi-process authority ledger: 4 processes, 100 events, chain ok True.
• IP portfolio: 106 invention records (consolidated register).

Limits. Libraries; the runtime stage is still opt-in and off by default. No staging soak, no third-party verification, no customers, no revenue, no patents. Physical AI is simulated only. The IP register is engineering invention-discovery, not legal advice. PRE-PRODUCTION.
