- description: Model provider-side charge verification through the deterministic mock settlement family.

- Compose provider-side charge pricing, challenge emission, credential

- verification, receipt sealing, and modeled forwarding for the deterministic

- mock settlement family.

-

- This graph profile is for local harnesses, demos, and contract tests. It makes

- the authority transition visible without claiming executable provider-side

- runtime forwarding.

-

- The deterministic path is complete only when priced bounds become an

- idempotent challenge, verification produces a mock proof reference, and a

- sealed receipt gates the modeled upstream result. Keep raw rail and merchant

- credentials out of every artifact. If verification cannot name its proof and

- sealed receipt, stop before the forwarding step.

-

- ## Output

-

- - `charge_price_packet`: provider-side price and requested authority.

- - `charge_challenge_packet`: `effect_required` challenge and idempotency key.

- - `charge_verification_packet`: mock settlement proof and receipt ref.

- - `charge_seal`: modeled child receipt seal.

- - `forwarded_result`: modeled upstream result gated by the seal.

-

- ## Inputs

-

- - `mcp_tool_call` (required): inbound MCP operation request.

- - `provider_policy` (required): provider price and family policy.

- - `returned_credential` (required): mock credential envelope or reference.

- - `parent_payment_authority` (optional): parent payment authority term or ref.

- - `verify_capability_ref` (required): single-use verification capability ref.

- - `idempotency_seed` (optional): stable challenge idempotency seed.
