Fig 02capability index

Eight surfaces with explicit behavior under failure, growth, and audit review.

Each capability page carries its own operating model, failure paths, and integration proof — the same dossier, one level deeper.

Acceptance and settlement lifecycle with routing control and deterministic state changes.

Issuing infrastructure with policy controls and authorization event visibility.

Idempotent movement, corridor routing, and support-visible settlement state.

Ledger-centric account structures and reconciliation-friendly posting model.

Minor-unit entries, double-entry discipline, and audit-linked money state.

Provider events, ledger state, settlement review, and exception evidence in one story.

Embedded KYC/AML screening and auditable risk decision workflows.

Signature-verified event contracts built for replay-safe consumers.

Financial systems stay resilient when every critical action is deterministic, traceable, and scoped.

Money movement needs explicit, inspectable transitions.

Distributed callbacks require strict consumer discipline.
