Remarks

The row's own columns and nothing else. The search document, the passages, and the vectors are derived from the message's text, which the same immutable bytes read by the same reader produce unchanged, so rewriting them would spend a re-cut and a provider bill to arrive back where they already are — ADR 0006 makes that a deliberately confirmed act rather than something a metadata refresh performs. Text written under a sensitive-content configuration this deployment no longer runs is the one case where it does change, and the extraction backfill's rebuild already owns it.
