## Business capabilities

## Dataset

Synthetic Zürich and Lyon customers, orders, tickets and refund policies.

License: Repository license; fictional people and example.com contact addresses.

Bound: 512 rows, 1048576 bytes.

## Journeys

### Verify and restrict customer identity

Actor: Support customer. A store credential can read policy but has no customer authority.

1. Ask for policy before verification. Expected: Only public policy is available.
2. Verify the caller and start a scoped session. Expected: The session binds its verified customer and store.

### Request and review refunds

Actor: Verified customer and store lead. The fixture includes eligible, large and ineligible refunds.

1. Request eligible and ineligible refunds. Expected: Rules return explicit business outcomes.
2. Have a store lead review the request. Expected: Only the authorized lead can decide.

### Enforce identity at tool dispatch

Actor: Untrusted caller. An agent token must confer only the session’s closed authority.

1. Try direct functions outside the session. Expected: Calls outside the session are refused.
2. End the session and try its token again. Expected: Ended sessions confer no access.
