Replay

Overview

Need to reproduce a previous decision? Use Replay.

Replay uses a replay_reference returned by Governed Execution to verify or reuse baseline runtime evidence. It helps customer systems anchor later Simulation, Comparison, and Governance RCA workflows to a known baseline.

When To Use It

Use Replay when:

Governed Execution returned a replay_reference.
You need baseline evidence for review, audit, Simulation, Comparison, or later traceability.
Replay material remains available according to current runtime behavior.

A replay_reference is a customer-visible lookup reference for runtime replay evidence.

What You Provide

Provide a non-empty replay_reference through the Replay endpoint using the exact request shape defined by the runtime source of truth.

Customer systems should preserve the relationship between the replay reference, the original Governance Artifact, policy setup, setup mapping, and any customer correlation metadata.

What FoxCommand Returns

A successful Replay response may include:

Runtime response API version
Status
Replay status
replay_reference
execution_id
contract_reference
Replay outcome
Bounded errors

Replay evidence is runtime evidence. It does not become customer governance source truth.

What To Do Next

Store the replay_reference and replay evidence in customer-controlled systems where needed.

Use Replay output as the baseline for:

Simulation, when evaluating candidate policy setup.
Comparison, when structured baseline-versus-candidate evidence is needed.
Governance RCA, when a material change needs bounded attribution.

Runtime Source of Truth

Use FoxCommand runtime documentation and the OpenAPI specification for exact request bodies, response bodies, authentication requirements, errors, replay availability, and operational limits.

Customer systems should not depend on runtime internals, generated contract bodies, storage layout, logs, traces, or replay implementation details.

Next Steps

Use Simulation when you want to evaluate candidate policy setup against replay-derived baseline material.
