	609	+ *
	610	+ * The presence hint the boot config ships as `hasNotes`: the notes
	611	+ * bundle is presence-gated client-side (`src/notes/sentinel.ts`), so
	612	+ * a user with no notes never downloads it — and never fires the
	613	+ * boot-time list request the layer used to make unconditionally.
	614	+ *
	615	+ * **Steady-state cost: zero queries.** The computed answer is cached
	616	+ * in user meta, stamped with a revision the site bumps whenever any
	617	+ * note changes (`openstation_notes_bump_rev()` below). The revision
	618	+ * lives in an autoloaded option and the user's meta cache is already
	619	+ * primed on every admin request, so a boot between note changes
	620	+ * reads two warm caches and touches the database not at all. Only
	621	+ * the first boot after a note is created / deleted / re-scoped runs
	622	+ * the probes again — two `fields => ids`, one-row queries at most:
	623	+ * anyone's public note first, the user's own private ones second,
	624	+ * mirroring the visibility rule the list route enforces.
