Audit log (agents)
An append-only record of agent actions written by infrastructure the agent does not control, providing ground truth about what happened as opposed to what the agent reports.
The independence is the point: agent-written records capture beliefs; hook-written records capture events. Audit logs serve governance (accountability), debugging (postmortems), and evaluation (checking memory and reports against reality).
Example
A lifecycle hook appending every tool call to a log the agent has no write access to.
