- PostGuard::editable() refuses trashed entries unless the caller opts in (content-get, revisions-list, post-trash); publish/schedule/unpublish/update/ restore/duplicate/replace now refuse them. - PostGuard::statusStable(): content-update, revision-restore and replace-with-copy refuse a future post whose date has passed (any save would publish it); the content-update rollback and PostCloner row writes re-check. - PostCloner::ownMeta() treats a failed SELECT as an error; replace() reads the copy before its first write. - replace-with-copy needs create_posts (backup clone) and reports backup_id in write_failed/partial_write.
