Verifiable Execution
Does Catalyst support incremental verification of an execution record as steps are still being executed?
Yes, Catalyst constructs the chained signature step-by-step, so a partially complete record can be verified up to the latest signed step. This enables near-real-time integrity checks. However, the partial record does not prove that the execution will complete successfully; it only confirms the integrity of steps recorded so far. Finality requires all steps to be committed and the record closed.

What is a verifiable execution record in Catalyst?
A signed, immutable sequence of agent steps enabling auditors to prove run integrity through independent replay. It does not validate decision correctness.
- Verifiable Execution
How does Catalyst ensure that step records are tamper-evident?
Catalyst uses a hash chain and digital signatures per step, so any alteration breaks the chain and becomes detectable through signature verification.

Can an auditor independently replay a Catalyst agent run to verify its outcome?
Auditors can replay runs using signed step records and initial state to verify output consistency, though non-determinism may limit exact reproduction.
