Debug log vs compliance-grade audit trail
Both record what happened — but they're built for different jobs. One helps you fix bugs; the other stands up as evidence.
| Debug log | Compliance-grade audit trail | |
|---|---|---|
| Purpose | Help engineers diagnose issues | Prove what happened, for auditors / customers |
| Mutability | Mutable, often rotated/overwritten | Append-only, tamper-evident (e.g. hash-chained) |
| Granularity | Stack traces, arbitrary messages | Agent action + inputs/outputs + human approval |
| Retention | Days–weeks, ad hoc | Defined policy (e.g. 6+ months) |
| Export | Grep / log viewer | Reviewer-friendly evidence export |
Why "tamper-evident" is the key word
Evidence is only worth as much as its integrity. If a record can be edited after the fact without anyone noticing, it doesn't answer “can you prove it?” Hash-chaining each entry to the previous one makes any later change detectable — which is what turns a log into an audit trail. See why SOC 2 reviewers ask for this.
Turn logs into evidence
AgentAudit is being built to record every AI-agent tool call and human approval — append-only and tamper-evident — and export it as SOC 2 / AI Act-ready evidence. It's in private beta.
