  "source_url": "https://zillq.com/sandbox76/agent-payment-test-cases",
  "scope": "Synthetic reference scenarios. Not an API schema, executable test runner, certification, or evidence of implemented controls.",
  "semantics": {
    "amounts": "Integer EUR cents, inclusive caps; positive payment amounts only.",
    "overrides": "Each case resets to the baseline. Merge setup.policy, setup.state and setup.request by field into the corresponding baseline object. request_variants and requests are also merged into baseline.request separately. second_request changes the baseline request after the first accepted attempt.",
    "identity": "Request owner_id and agent_id stand for verified context; never trust client claims without validation.",
    "budget": "available = period_limit_minor - committed_minor - reserved_minor; reservation is atomic per mandate and period. Period is [period_start, period_end), and validity excludes expires_at.",
    "counts": "new_payment_count and new_reservation_count count logical operations added by this scenario, excluding the baseline state.",
    "multi_failure": "A case can fail more than one rule. The reason names the focal check; it does not require a universal error-precedence order.",
    "sequence_cases": "The replay, concurrency and recovery cases require a stateful adapter; a stateless predicate cannot validate them.",
    "allowed": "allow means eligible under this sample agent policy; bank consent, authentication and provider checks still apply."
