After purchase, cancellation, refund, exchange and change are new side effects. **Original purchase consent is not automatically authorization for post-booking servicing.**

## Cancellation and refund

The agent should quote cancellation penalty, refundable amount, timing, payment method and provider restrictions before mutation. Execute only after explicit user authorization or a valid servicing mandate.

## Consent versioning

Bind consent to booking version, quoted penalty/refund, currency, operation and timestamp. A changed quote invalidates old consent.

## Traceability

Preserve userIntent → servicingIntentId → quote/version → authorization evidence → tool call → provider attempt → provider reference → reconciliation record.

## Audit record

Record who/what acted on whose behalf, operation, booking/version, quote, authorization, agent/model/tool execution and outcome.

## Agent explanation

Explain what changed, expected refund/penalty, whether the operation is confirmed or pending and whether another action is required.

## UNKNOWN servicing

Never summarize UNKNOWN as completed. Keep it pending and trigger reconciliation.

## Data minimization

Auditability does not require storing raw prompts or full PII. Prefer structured evidence IDs and redacted summaries.

## Failure modes

Stale quote cancellation, reused old consent, missing reapproval after refund changes, treating UNKNOWN as success, storing PII in prompts and losing agent/model version evidence.

## Observability

Track servicing consent, quote-change reapproval, servicing UNKNOWN, cancellation/refund success, audit completeness, manual intervention and disputes.

## Production checklist

Use separate servicing mandates, quote-before-mutate, consent versioning, immutable audit evidence, agent/model/tool traceability, UNKNOWN reconciliation, PII-minimized audit and user-facing outcome explanations.
