// restructure: rewrite in step 1 (Connection + Identity + Presence): the
// feed rows follow the new feed actions one-to-one (away/in/gone/return);
// step 2 (Status + Notifier): every row, when noticeFor takes a context.
//
// The Notifier policy as a table: one row per AppEvent subtype, what
// noticeFor makes of it (toast text and actor, sound, attention, activity-log
// line). A policy change edits a row here on purpose.
