Sandbox only. No real funds moved. No production access is granted here. Access requirements

Rehearsal boundary

Rehearse in sandbox, enable through evidence

Sandbox rehearses with synthetic identities and no real funds; live enablement follows evidence review and explicit approval.

Ownership and runbook

Owner: Developer Platform. Runbook: RB-API-SECURITY-OPS-001. Sandbox uses synthetic identities and deterministic outcomes with no real funds and no production authority.

Sandbox boundaries

Rehearse with identities such as merchant mer_01900000000000000000000000, store store_01900000000000000000000000, and developer app dapp_01900000000000000000000000. Responses carry an execution mode that marks the rehearsal boundary.

Prohibited

Never promote a sandbox grant to live by editing a response, reusing a sandbox identity in production, or treating a successful rehearsal as an activation record.
