Overview

A declared map from one era of a domain's storage shape to the next. Renames and moves — the smallest slice that proves the concept: old records are translated when they are replayed, never rewritten. retired acknowledges aggregates that are gone outright — not renamed — so their disappearance is a decision, not an accident.
