Git gives every memory system time for free — when we recorded it. It does not give when it was true. Separating event time from record time is what turns "what did the file say on this date" into "what did we believe was true as of this date" — the question an auditor actually asks. Design sketch: optional valid_from/valid_to on records or claims, additive frontmatter, ranker awareness. Open for design discussion; implementation follows the discussion, not the other way around.
