- Replace fixed 16-min window with per-event variable-lead fire-time check
- Two separate DB queries: timed (allDay=false) + all-day (allDay=true)
- Remove eq(calendars.isShared, true) — personal events now dispatch (NOTIF-05)
- Remove eq(calendarEvents.allDay, false) — all-day handled in separate query
- Add reminder_lead_minutes IS NOT NULL WHERE predicate (NOTIF-05)
- Skip timed events with reminderLeadMinutes===0 in JS (D-06: 0 on timed = None)
- Change dedup key from bare uid to uid:dtstartMs compound key (NOTIF-06)
- Update prune loop to use compound key
- Import computeAlertInstantUtc from vevent.js (Plan 11-01, wave 2 dep)
- Add humanizeLeadMinutes export (Task 2 body formatter, used in dispatch)
- Update test helper mockTwoQueries() to handle two-query dispatch pattern
- All 14 tests GREEN; tsc --noEmit clean; setInterval retained, no node-cron
- Replace shared+timed filtering tests with NOTIF-04/05 variable-lead tests
- Add timed-0 guard test (D-06: 0 on timed = None — currently FAILING)
- Add personal-calendar dispatch test (isShared restriction dropped)
- Update SINGLE-FIRE test to assert uid:dtstartMs compound key
- Add RESCHEDULE test: new dtstartMs re-fires even for same uid
- Update MISSED-TICK-RECOVERY to use 60s catch-up window
- Add reminderLeadMinutes field to all makeEventRow() calls
- tests/fixtures/vapid.ts: static TEST_VAPID keypair for offline unit tests
- tests/lib/pushDispatcher.test.ts: RED — 410/404 prune + 201/5xx no-delete
- tests/lib/pushCoalescer.test.ts: RED — burst coalesce fires once with count=N; excludeUserId
- tests/broker/reminderScheduler.test.ts: RED — shared+timed filter; dedup by (uid,minuteBucket)
- tests/lib/eventChangeDispatcher.test.ts: RED — create/meaningful-update fires; description-only silent; actor excluded
- tests/routes/push.test.ts: RED — POST 201/401; DELETE removes rows; GET vapid-public-key
- test/setup.ts: import pushSubscriptions + add db.delete(pushSubscriptions) in afterEach
- all 5 RED files fail on missing-module (correct; implementations in Plans 05-02..05-06)
