- A fetched ObjectRecord no longer wears the signature, key, signed headers and @context of the activity that caused the fetch, and its ReceivedAt is the fetch's own time. Its activity fields now name the trigger. Provenance answers signature null and fetchedBy "instance-actor". Migration _008 clears the old fetched records. - ObjectRecords store their ObjectFeatures extensions and context namespaces (migration _009 fills older records in batches), so statistics can count them. Provenance reads the stored lists. - ForeignAvatar.Features records what an actor document uses (ActorFeatures): featured, shared inbox, FEP-521a, FEP-8b32, identity proofs, Misskey fields, indexable, undiscoverable, locked, key size, and more. - RemoteEdits.Apply and RemoteDeletes.Remove are shared by the Update, Delete and Announce handlers. A community-wrapped Update is now an edit only when newer, refreshes polls and media otherwise, revises the ObjectRecord and re-resolves quotes. A community-wrapped Delete now tombstones the object, removes its ObjectRecord, reblogs and timeline rows, and lowers the reply count. Any deleted quoting post lowers the quoted post's quote count.
