Quick Task 260610-hbu: Reminder Scheduler Resilience Verification Report
Task Goal: Make the Phase 5 reminder scheduler resilient to missed/late cron ticks — catch-up scan + per-uid exactly-once dedup Verified: 2026-06-10T12:39:30Z Status: passed Re-verification: No — initial verification
Goal Achievement
Observable Truths
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | A shared timed event in (now, now+16min] fires on the next scan even after a missed/late tick (catch-up). | VERIFIED | gt(calendarEvents.dtstartUtc, now) at line 103; lower bound is now, not now+14min. Any scan while event is still future will find it. MISSED-TICK-RECOVERY test fires at 8-min lead. |
| 2 | A given event fires EXACTLY ONCE across all scans while in the catch-up window — no cross-tick double-fire. | VERIFIED | sentReminders is Map<string, number> keyed on bare uid (line 47); if (sentReminders.has(uid)) continue at line 145. SINGLE-FIRE test asserts dispatchPush called exactly once across 3 consecutive ticks. |
| 3 | An event whose dtstart has already passed (dtstart <= now) does NOT trigger a reminder. | VERIFIED | gt(calendarEvents.dtstartUtc, now) at line 103 excludes already-started events at the DB level. "already-started" test mocks empty rows, asserts 0 dispatches. |
| 4 | Notification body reflects actual lead time (e.g. "Starts in 8 min"), guarded to minimum 1. | VERIFIED | Line 150: const minutes = Math.max(1, Math.round((event.dtstartUtc.getTime() - now.getTime()) / 60000)) then body: \Starts in ${minutes} min`` at line 156. Not hardcoded. |
| 5 | Existing Phase-5 behaviours stay green: isShared-only (D-05), allDay excluded (D-07), always-visible notification (D-11), empty push_subscriptions -> zero sends/no crash (D-16), per-event and per-sub error isolation (T-05-18/T-05-19). | VERIFIED | All present in source (lines 101-102 for D-05/D-07; line 98 for D-11 via dispatchPush; lines 141-186 for T-05-18/19 try/catch isolation). Tests for D-05, D-07, D-16, T-05-19 all pass (10/10). |

VERIFIED | Line 103: gt(calendarEvents.dtstartUtc, now). Line 104: lte(calendarEvents.dtstartUtc, windowEnd). |

Anti-Patterns Found
None. No TBD/FIXME/XXX markers in modified files. No hardcoded empty data. No stubs.
The two minuteBucket occurrences at lines 42 and 142 of reminderScheduler.ts are comment text only (no variable), correctly documenting the old scheme for historical context — not a stub indicator.
Human Verification Required
None. All must-haves are verifiable programmatically and confirmed by running commands.
Gaps Summary
No gaps. All 5 must-have truths are VERIFIED against the actual codebase:
- Catch-up window implemented:
gt(dtstartUtc, now)lower bound (notgte(now+14min)) confirmed in source and tested. - Per-uid exactly-once dedup:
Map<string, number>keyed on bare uid confirmed;minuteBucketvariable fully absent. - Already-started exclusion: strict
gtlower bound confirmed; test coverage present. - Lead-accurate body:
Math.max(1, Math.round(...))formula confirmed in source. - Phase-5 decisions preserved: D-05/D-07/D-11/D-12/D-16/T-05-18/T-05-19/WR-01/CR-01 all present in source and tested.
- Typecheck: exit 0.
- Test suite: 10/10 passing, including the three required new tests (SINGLE-FIRE, MISSED-TICK-RECOVERY, already-started exclusion).
