# Record

Every act on every layer, by a person or an agent, in one trail.

The audit trail names who did what to which resource and how it came out. Events and usage say what the company did and what it cost. An agent’s run is recorded the same way a person’s request is, which is what lets a company read what its agents did before it gives them more room.
