The minified release build crashed on every launch before any UI:
Unable to get provider androidx.startup.InitializationProvider:
Failed to create an instance of androidx.work.impl.WorkDatabase
The home-screen widgets use Glance, which pulls in WorkManager and its
transitive Room database (room-runtime 2.2.5). Room 2.2.5's bundled keep
rule is `-keep class * extends androidx.room.RoomDatabase` — it keeps the
class but not its constructor. Under R8 full mode (AGP 9) the generated
WorkDatabase_Impl was reduced to a non-instantiable class, so Room's
reflective newInstance() threw InstantiationException at startup.
Add `-keep class * extends androidx.room.RoomDatabase { *; }` so the
generated *_Impl classes keep their constructors. Verified against the
rebuilt release APK: WorkDatabase_Impl is now PUBLIC FINAL with its
<init> present.

Completes v2.7 Branch 2. Wires the import core into the app:
- Manifest ACTION_VIEW/SEND for text/calendar; MainActivity parses the
incoming Uri (content/file only, so calendula:// deep-links don't match)
and routes it through RootScreen → CalendarHost like the other one-shot
intents.
- ImportViewModel reads + parses the file and routes by count: one event →
the prefilled create form for review (EventEditViewModel.openImported,
which freezes the reminder default so the file's reminders win); many →
ImportScreen with a writable-calendar picker, then a bulk import (UID
dedup) and a result summary.
- ImportScreen also surfaces parser warnings (skipped recurrence overrides,
ignored attendees, unknown-timezone fallback). Strings EN+DE.
Package is ui.imports (not ui.import — Java keyword). lint + test +
assembleDebug green. No v2.7 tag until on-device review.

v2.7 Branch 2 (core, no UI yet). The read side of the .ics engine:
- domain/ics: IcsParser (inverse of IcsWriter) — unfold/unescape/param
parsing, VALUE=DATE / UTC-Z / TZID date handling resolved against the OS
tz db, VEVENT walk → ParsedIcsEvent + typed warnings. Liberal-in/
strict-out: a malformed VEVENT is skipped, RECURRENCE-ID overrides /
attendees / unresolved TZIDs are reported, not silently dropped.
- Promoted parseRfc2445DurationMillis into domain/ics (shared by writer-
side mapper and parser); IcsDuration + test.
- Datasource existingUids()/insertImportedEvent(); repository
importEvents() with UID dedup (skip known UIDs → idempotent restore) →
IcsImportSummary. IcsImporter reads a Uri's text.
- ParsedIcsEvent.toEventForm() for the single-event "open into the create
form" path.
Parser round-trips against IcsWriter; dedup + form-adapter unit-tested.
Intent filter, routing and import UI land in the next commit.

All-day events live at UTC midnights with an exclusive end, but coversDay
sliced each day in the device timezone. East of UTC the exclusive end
landed a few hours into the next local day, so a one-day all-day event
(e.g. a birthday) rendered on two days in the day/week/month views — while
the detail and edit screens, which work in UTC, showed it correctly.
Compare all-day coverage in UTC and step the exclusive end back to the
last covered day, mirroring the detail/edit views.

v2.7 Branch 1 of 2: .ics export — single-event share + whole-calendar backup of local calendars. Import (feat/ics-import) lands next in the same release.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Branch 1 of 2 for v2.7 (the .ics topic). Adds the write side of a
hand-rolled RFC 5545 engine (zero deps, stays on kotlinx-datetime):
- domain/ics: IcsText (escape + 75-octet folding), IcsEvent model,
IcsWriter.writeCalendar. Timezone rule: all-day VALUE=DATE, one-off
timed UTC Z, recurring timed TZID-labelled from EVENT_TIMEZONE (no
VTIMEZONE — import resolves TZID against the OS tz db).
- Single-event share from the detail screen (FileProvider + ACTION_SEND).
- Whole-calendar backup of the writable local calendars to a SAF file
(Settings -> Calendars -> Export as .ics), one combined VCALENDAR.
- insertEvent now writes Events.UID_2445; legacy rows fall back to a
stable synthesised UID at export time so a later restore won't dupe.
- EXDATE / RECURRENCE-ID overrides are deliberately skipped this pass
(documented v1 limit; import will skip them too).
Engine + mapper unit-tested. Import (Branch 2, feat/ics-import) ships in
the same v2.7 release; no tag until both land + on-device review.
