Verifiable Execution
Can I validate Catalyst’s verifiable records using only open-source cryptographic libraries, without Catalyst software?
Yes, Catalyst signs steps with standard algorithms such as ECDSA and publishes the record format. An auditor can verify step signatures using any open-source crypto library that supports these primitives. However, re-running the agent to validate the outcome requires access to the exact agent code and model versions; Catalyst’s runtime normally handles this, so independent replay may be complex but signature verification alone is straightforward.

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.
