01
Replay is more than opening an audit log.
A chronological log can show that events occurred. Replay asks whether the retained inputs and governing versions reproduce the same decision record.
If the evidence, policy, manifest, authority or integrity chain is missing or inconsistent, DTF refuses to manufacture a successful result.
02
A replayable record keeps the dependencies together.
Bound evidence
The record identifies what was available when the decision was made.
Policy provenance
The decision retains the exact governing policy reference.
Authority record
The authorised actor and approval path remain inspectable.
Integrity proof
Verification detects a changed or incomplete copy.
03
Replay supports assurance, investigation and learning.
Teams can reconstruct a challenged decision, inspect a human override, compare repeated decision patterns and test whether a retained record still verifies after surrounding systems have changed.
