docs(03): Gate 2 complete for Phase 03 scope — D3 recurring write verified, recurring-series delete confirmed

Weekly recurring create writes valid RRULE and recurred in Fastmail; repeat-bound
+ per-occurrence-duration UX gaps backlogged (999.7/999.8). Deleting the recurring
series cleared master + all occurrences in one delete. Remaining deferred by
design: B5 (Android), C (SSE smoke — Phase 4 entry gate).

 | D1 | CAL-04 | Create a timed event → "Syncing…" toast → "Saved" toast → event appears in native Fastmail app on next sync | ✅ PASS (2026-06-07) | Timed create round-trips to caldav.fastmail.com (outbox rows reach `done`); appears in the app. Timezone fix applied (was 4h off). |
 | D2 | CAL-07 | Create an all-day event → same Syncing→Saved flow → appears in Fastmail | ✅ PASS (2026-06-07) | All-day create round-trips to Fastmail (verified VEVENT: DTSTART/DTEND VALUE=DATE, exclusive end). Found + fixed a display off-by-one (single-day showed across 2 days — Schedule-X inclusive vs iCal exclusive end; commit d4d5327). Reload to confirm 1-day rendering. |

+| D3 | CAL-04 | Create a weekly recurring event → appears in Fastmail | ✅ PASS — write correct; UX gaps backlogged | A weekly event was created and recurred in Fastmail with a valid `RRULE:FREQ=WEEKLY`. Two UX gaps surfaced (NOT write-correctness): no "repeat until/count" bound (series is unbounded → recurs into 2028+) and the end-date is the per-occurrence duration (a 2-month end made each occurrence 63 days → overlapping every day). Backlogged 999.7/999.8. Deleting the recurring series cleared the master + all occurrences from Fastmail in one delete (recurring-series delete verified). |
 | D4 | CAL-05 | Edit an existing event's title and time → Syncing→Saved → change persists in Fastmail | ✅ PASS (2026-06-07) | Edit/move confirmed working; update outbox rows reach `done`; post-write refetch race fixed so the change shows without manual refresh. |
 | D5 | CAL-06 | Delete an event via the two-tap confirmation dialog → Syncing→Saved → event disappears from all views on next sync | ✅ PASS (2026-06-07) | Delete confirmed working; delete cache-reconciliation fix means the event leaves the cache/UI (was lingering as a ghost). |
 | D6 | D-08 | (Optional) Trigger a 412 conflict by editing the same event in Fastmail first → conflict toast appears in the app → calendar re-fetches | ✅ PASS (2026-06-07) | Observed live: a stale-etag update produced `412 conflict` (outbox id=7) and the "This event changed elsewhere" conflict toast; calendar re-syncs. |
