Replay

Paste a decision hash. Watch the chain rebuild itself.

Every H33 receipt carries the hashes needed to reconstruct the decision: authority, policy, evidence, preconditions. This viewer walks the chain step by step — sample decisions today, real replay when the backend endpoint ships.

1 · resolve authority
2 · resolve policy at timestamp
3 · resolve evidence
4 · resolve preconditions
5 · re-derive decision hash
6 · verify PQ signature

In 5 sentences

What is itInteractive decision replayer. Reconstruct any historical decision from the receipt alone by walking the 6-step chain: authority → policy → evidence → preconditions → re-derive decision hash → verify PQ signature.
Why it mattersAuditors need to answer 'why was this decision valid at that specific moment?' A replayer that walks the receipt cryptographically answers it without asking H33 for anything.
When to useWhen investigating a specific historical decision — an approved payment, an AI agent action, a document signature. Also useful as an architectural demonstration for compliance stakeholders.
How it differsClient-side chain walk today (demo mode). The receipt itself carries the reconstruction data — H33 is not queried during replay.
Evidence8 capabilities support in-Vault replay today. Sample decisions in demo mode walk real receipt shapes. Public /replay/<hash>/ backend ships next.
