 - Recurring events: Create + display only in v1 (CALDAV:expand on server side). Single-occurrence edit deferred to v1.x.
 - [Phase ?]: D-Task5-DDL: drizzle-kit push unsafe on MariaDB 11 (mysql dialect misreads metadata, schedules truncate). Additive DDL hand-applied; adopt drizzle-kit generate+migrate before next schema change.
 - [Phase ?]: D-02-RRULE: use ICAL.Recur.fromString + ICAL.Property for RRULE serialization — addPropertyWithValue produces char-split output for RECUR types
+- [Phase ?]: resolveUserId helper uses any type to avoid Hono context generic complexity — internal helper only
+- [Phase ?]: Write endpoints enqueue-only (calendarOutbox) with 202 optimistic-accept; no Fastmail call in routes (D-12/D-05)
+- [Phase ?]: GET /writable-calendars is authoritative D-03 writable-set endpoint: WHERE userId=currentUser.id OR isShared=1
