Validating deterministic contract

AGENT-NATIVE EVIDENCE INFRASTRUCTURE

Flight recorder for autonomous decisions

Portable state is not valid state.

When reality changes, MatchFlight identifies every conclusion that must change with it.

Every conclusion remains provisional until the complete public contract verifies.

    Apply the invariant

    Test a public agent-payment flow without a meeting.

    $1,500 fixed scope. Eight deterministic negative-path cases, one runnable Node regression harness, machine-readable findings, and prioritized remediation notes within a 48-hour target.

    Asynchronous; no meeting, credentials, wallet connection, signing, or settlement action. A request moves no funds and authorizes no payment. Work and payment require a separately human-approved SOW and invoice.

    A second outside-the-model invariant

    Constrain authority before action; preserve evidence validity after observation.

    Sentinel Payment Boundary is a separate local, read-only preflight for declared payment metadata before delegated wallet authority is considered.
