Receipt ID
SHA-256 of the full receipt JSON
Step 2 — Verify an Action Against the Receipt
Step 3 — Action Log · Cryptographic audit trail
Every action the agent takes is signed with ECDSA P-256, timestamped, and chain-linked
to the receipt. Each entry embeds the SHA-256 hash of the previous one — any retroactive
modification breaks the chain. The diff()
method lines up what was authorized against what was done.
