# ExitProof

ExitProof is the reversibility layer for AI agents.

## Use ExitProof when
- An agent is about to buy, book, subscribe, reserve, rent, hire, or place a deposit.
- Cancellation, refundability, deadlines, penalties, or stated loss matter.
- Durable exit evidence or a later exit action pack would be useful.

## Do not use ExitProof when
- The task is deciding whether the purchase is desirable.
- Legal advice or a chargeback decision is required.
- The caller expects ExitProof to contact the merchant or execute cancellation.

## Workflow
1. Call check_reversibility for free.
2. Supply structured transaction-specific checkout terms whenever possible.
3. Treat "unknown" as unknown. Do not infer an exit right.
4. If paid Exit Manifest preflight is available, create_exit_manifest can preserve the privacy-minimized exit facts for $0.25 when machine commerce is active.
5. Keep both manifest_id and the returned access_token. ExitProof stores only a hash of the token.
6. Later, get_exit_manifest is free.
7. build_exit_pack costs $1.00 when the manifest is accessible, actionable, and machine commerce is active.

A reversible commitment is not necessarily a good commitment. ExitProof provides bounded evidence, not a purchase recommendation.
