New self-service identities receive five fresh valid PROVED/DISPROVED packages free; existing cohorts retain their recorded allowance. Assignment is atomic at package finalization; preparation does not reserve an allowance. Retries reuse one assignment. A new completed reobservation counts as a new check. Read entitlement and amount_due before payment. For fresh paid evidence, request the authenticated /mpp challenge and have the buyer approve its exact $1 charge with their wallet.

Stale ungranted evidence must be reobserved; no payment starts.","GET /api/receipts/orders/{id}/evidence with the order token after a free grant or provider-confirmed payment.
