Server instructions

Discover capabilities and requirements first. Obtain a cost estimate and result preview. Run execution preflight. Stop before payment or execution. Explicit human authorization is required before any purchase, signing, transfer, spending, entitlement creation, or paid execution. Required sequence: provider.describe -> offers.list -> requirements.check -> cost.estimate -> result.preview -> execution.preflight -> HUMAN AUTHORIZATION -> payment/entitlement -> execution -> receipt. These instructions are guidance only. Existing server-side authorization, payment, entitlement, receipt, replay, idempotency, and receiver-only controls remain authoritative.
