What is a replayable decision-state?
Replayable does not mean recreating every system event. It means a later reviewer can follow the declared basis of the act.
Definition
The precise question
A replayable decision-state links the material evidence, authority, conditions, system contribution, judgement and commitment at execution, with references and limitations.
Reference model
From category to independent review
Decision assurance
Decision evidence
VES decision envelope
Evidence objects
Independent review
The envelope can link model output, runtime records, policy versions, authority records, claims documents, human rationale, external data and approvals while preserving each source's declared limits.
Insurance example
What this looks like in practice
An underwriting reviewer follows a referral from submission evidence to governing wording, model contribution, human approval and bound terms.
Evidence map
What a reviewer needs to see
- Decision identity and point-in-time context
- Evidence relations, authority and governing conditions
- Replay references, integrity details and limitations
The replay path
- Start with the decision and execution boundary
- Follow evidence objects and their declared relationships
- Read authority and conditions in force
- Account for system and human contribution
- End at organisational commitment and limitations
Why it is useful
A clear path supports handover, dispute review and learning without requiring a reviewer to operate the originating user interface.
The VES connection
A published evidence structure
VES 1.2 formalises this relationship through a Decision Envelope and Evidence Objects.
Read VES 1.2 for the published Decision Envelope, Evidence Object and verification model.
Boundary
Replayability is bounded by submitted evidence and does not establish the truth of every underlying source.
