Verifiable Execution
How does Catalyst prove that the sequence of steps in an agent execution has not been reordered?
Catalyst chains step records with cryptographic hashes to prevent undetected reordering. Each signed step includes the hash of its predecessor and a sequence number, creating a verifiable linked list. Verification checks that the chain is intact, confirming no steps were inserted, removed, or reordered. However, this ordering proof relies on the integrity of the initial step; if that step is falsified, the entire chain could be suspect.

- Verifiable Execution
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.
