F3 memory edits go through the same privacy shaping as proposals; F5 seq is
derived from the ledger tail so a crash between append and checkpoint never
duplicates; F7 transitions re-read under the lock and always write with the
loaded revision; F9 secret scrub on titles, passages, claims and notebooks
and forget blanks the conversation document; F13 no ghost conversations
from notices, idempotency under the lock, artifact titles searchable,
normalised paths.
