AI audit logs
An audit log and an audit trail are usually the same thing described two ways: the log is the entries, the trail is what those entries add up to when you follow them through a decision from start to finish.
An AI audit trail, sometimes called AI auditability, is a record of every action an AI system and the people managing it took: who asked what, what the agent answered, who corrected it, and when a setting changed. The record only does its job if it cannot be quietly edited afterward, which is a stronger requirement than simply being logged.
An audit log and an audit trail are usually the same thing described two ways: the log is the entries, the trail is what those entries add up to when you follow them through a decision from start to finish.
Three names for the same underlying record used for three different purposes. A decision audit trail reconstructs why one particular answer was given. A compliance audit trail is that same record handed to someone outside the business, an auditor or a regulator, as evidence rather than as an explanation. An agent audit log is the record filtered down to one agent, which matters once a company is running more than a handful of them and needs to look at one at a time.
Tamper-evident means an alteration is detectable, not merely that alteration is discouraged. Augela hash-chains every entry, so each one's hash depends on the entry before it: editing or deleting a past entry breaks every hash that comes after it, and that break is what re-verification on export catches. A log that can be quietly edited after the fact is not evidence, it is a claim.
Accountability needs an answer to two questions a log alone does not provide: who owns this agent, and who is responsible for the rules it operates under. Augela assigns an owner to every agent, with a sensible fallback if nobody was ever explicitly assigned, so accountability does not depend on someone remembering who set it up.
An activity log is broader than an audit trail: every request, every retry, every background check an agent runs. An audit trail is the subset of that activity that matters for accountability and compliance, kept to the same tamper-evident standard as everything else, rather than every log line a system happens to produce.
A governance audit is the moment the audit trail is handed to somebody outside daily operations to review. The record exports to CSV or JSON with the hash chain re-verified at export time, and can stream to a company's own security monitoring system if it has one, so the evidence a governance audit needs does not have to be assembled by hand after the fact.
