Capture rules

5 rules · all active

R01Always capture all 4 strataactive

Every agent action seals S(a) Transaction, S(b) Configuration, S(c) Behavior profile, S(d) Capability. No opt-out.

R02S(c) behavior re-queryactive

30 counterfactual re-queries per action under preserved state. Computes modal action, runner-up, and replay sharpness.

R03Hash + timestamp before dispatchactive

BLAKE3 hash computed and RFC 3161 timestamp applied before the agent action dispatches to counterparty. Evidence precedes action.

R04Authority ceiling checkactive

S(b) records the agent's authority ceiling from configuration. Actions exceeding authority flagged for human review before dispatch.

R05Storage redundancyactive

Every sealed Evidence Package written to primary WORM bucket + off-region replica. Integrity re-verified daily.
