The bar is external proof.

Strict temporal Replay

Decision-time manifests, future-field exclusion, explicit cohort selection, and deterministic controlled acceptance.

Prospective real arrivals with independent outcome adjudication.

Operating contracts and grants

Versioned grants, distinct workspace principals, explicit signature ceremonies, promotions, and recalls.

Partner authority review and real countersignatures.

External action and read-back

Signed adapter contract, durable claims, recovery, read-back, postconditions, and receipt binding.

A conforming partner system and limited live work class.

Portable evidence

Downloadable bundle and public content, contract, execution, receipt, and server-attestation verifier.

Independent reconstruction from a live partner effect.

Horizontal transfer

One declarative job kernel plus a clean formation → mapped cohort → temporal Replay acceptance path.

Frozen core and at least two genuinely held-out partner domains.

Outcome and economic evidence

Prespecified measurement and evidence requirements.

Mature outcomes, fully loaded costs, adverse events, and a credible counterfactual.
