Record monitoring changes as decisions with evidence
Separate model, data, metric and policy changes so a report’s status remains interpretable.
Replace a reference baseline without erasing the old comparison
Use parallel evidence and explicit identities when the reference population or frozen bins change.
Plan rollback around a complete monitoring artifact
Restore code, inputs and definitions together, and replay historical evidence without rewriting what happened.
Use a frozen reference report to make changes inspectable
Separate a fixed teaching edition from interactive calculations and preserve enough evidence for replay.
