CI's static lane counts opted-out ts fences repo-wide and the note's
ignore-check sketches tipped the ratio past 50%. The hub/backend/event
shapes those fences sketched are all shipped code now, so the sections
point at the owning source files (src/index.ts, src/backend.ts,
src/error.ts, src/events.ts) instead of restating signatures; both
language sides move together and the pairing record is re-confirmed.
