Pro Tips

Small moves that make the checklist easier to finish

If you cannot reconstruct a decision, you cannot defend it. The audit trail is not overhead, it is the thing that answers for the AI when a regulator or counterparty asks.
Version provenance is the detail teams skip and regret. A prompt or model change with no log means a past decision becomes unexplainable the moment the deployment moves on.
Test the reconstruction before you need it. The first time you actually try to rebuild a decision from logs is when you discover which field you forgot to capture.
