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.

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.

The in-app language picker silently did nothing: AppCompatDelegate.set
ApplicationLocales only syncs to the system from an AppCompatActivity, but
MainActivity was a plain ComponentActivity (with a platform theme). Switch
MainActivity to AppCompatActivity and base Theme.Calendula on
Theme.AppCompat.DayNight.NoActionBar.
Changing the locale recreates the activity; set android:windowBackground to a
DayNight colour matching the Compose background (light #FBFCFE / dark #101316)
so the recreation no longer flashes a contrasting backdrop.

All-day events live at UTC midnight, so a raw "1 day before" reminder
fires at an off hour (02:00 local in CEST) rather than the morning. Add a
global "all-day reminder time" setting (default 09:00) and encode it into
the provider MINUTES offset so the reminder lands at the chosen wall-clock
time the day before instead.
- AllDayReminderEncoding: pure to/from provider-minutes helpers, keeping
the form/UI/diff in whole-day "semantic" minutes and converting only at
the Reminders read/write boundary (insertEvent, reconcileReminders,
EventDetailMapper). Covers DST, negative offsets, and pre-existing rows.
- SettingsPrefs.allDayReminderTimeMinutes (default 540) threaded from the
repository into the data-source write paths.
- Settings: a time-picker row, plus a shared TimePickerAlert lifted from
the event editor.
- Fix the time picker's 12/24-hour detection: honour an explicit system
override, else fall back to the device locale rather than the app's
per-app language, so it matches the rest of the device.

Make the supported-language list a single source of truth so community
translations show up with no code change: add res/xml/locales_config.xml
(en, de) and reference it via android:localeConfig, which also surfaces the
per-app language entry in Android 13+ system settings.
Rewrite AppLanguage to parse locales_config.xml for the supported BCP-47
tags and expose currentTag/apply/displayName (autonyms), dropping the
hardcoded LanguagePref enum; the Settings picker is now built from that list.
Remove the now-unused settings_language_german/english strings.
Adding a language is now: drop in values-<tag>/strings.xml and add one
<locale> line.

Bundles the unreleased Tier 2/3 work into one release:
- Home-screen widgets (Glance): an "Upcoming" agenda widget and a month-grid
widget, both reusing the in-app grouping/layout (groupAgendaDays,
layoutMonthWeeks) via a Hilt WidgetEntryPoint, honouring hidden-calendar
filters and refreshing on PROVIDER_CHANGED / date rollover.
- App shortcut: launcher long-press "New event", routed through the shared
WidgetNavRequest.Create channel into the create-event form.
- Agenda view and jump-to-date (already merged via #3/#4) are documented here
as part of the shipped version.
Bumps versionCode 20500 / versionName 2.5.0, moves the CHANGELOG Unreleased
section under [2.5.0], updates ROADMAP/STATE, and adds EN+DE strings.

The fourth top-level view, alongside Month/Week/Day. A forward-looking
LazyColumn of upcoming events grouped under sticky day headers, reusing
the v2.3 grouped-list language (GroupedRow cards, color-rail leading).
- AgendaViewModel loads a 60-day forward window from the anchor day
(today by default; goToToday/goToDate drive the FAB + drawer jump),
groups instances by local day (ongoing/multi-day clamped to the
anchor), sorts all-day-first then by start.
- AgendaScreen: same drawer + scaffold + view-switcher + FAB shell as
Day; sticky "Today · …"/"Tomorrow · …" headers, event rows with
time·location, plus empty/failure/loading states.
- Wired into CalendarView (ViewAgenda icon), IMPLEMENTED_VIEWS, and
CalendarHost; strings added (EN + DE).

Add a "Jump to date" row to the drawer (under the View switcher) that
opens an M3 date picker and navigates the active view to the chosen day,
sliding in from the correct side. Wired across Month/Week/Day, each
seeding the picker with its visible anchor (day / week-start / 1st-of-month).
Extract the form's private date-picker into a shared
ui/common/CalendarDatePickerDialog so the event form and the drawer share
one picker; add goToDate() to the Month and Week view models.
Reprioritises the roadmap: jump-to-date is now next; duplicate-event drops
to the bottom as low-importance.

Optional per-event color in the event form. The read/render path already
resolved EVENT_COLOR with a calendar fallback; this adds the write side and
the picker.
- Palette-backed calendars (Google, some CalDAV) pick from the account's
Colors (TYPE_EVENT) and write EVENT_COLOR_KEY, so the color round-trips
through sync; local calendars write a raw EVENT_COLOR from the shared
CALENDAR_COLOR_PALETTE. Never writes a raw color to a palette calendar.
- Swatch row + palette extracted to ui/common/ColorSwatchRow.kt (shared with
the calendar editor). Switching calendars resets the choice (keys are
account-scoped); a "Reset" action returns to the calendar color.
- New "Allow colors on unsupported calendars" setting (off by default)
extends the raw path to no-palette synced calendars, with an honest
"may not survive sync" warning on the picker and in Settings.
- Color flows through insert / dirty-checked update / occurrence-exception;
mapper, form, and repository tests added.

One shared Material 3 grouped-list blueprint, modelled on the ReFra gallery app
and extracted to ui/common/GroupedList.kt: CollapsingScaffold (a LargeTopAppBar
whose large title collapses into the bar on scroll) and GroupedRow
(Position-based corner grouping so a run of rows reads as one rounded card, with
press-animated corners and selected/minHeight knobs).
Settings: restructured into a category hub (About card on top, version mark at
the foot) with sliding sub-pages for Appearance, the new-event form and
Notifications. Theme, week-start and language pickers migrated from DropdownMenu
to OptionCard dialogs; token-based icon chips. New ic_gitea.xml (Simple Icons,
verbatim path) for the About "Source" button; en+de strings.
Calendar manager: same collapsing scaffold + grouped rows; shared
CalendarColorChip (neutral chip with a pastelised calendar glyph) replaces the
bright colour swatch.
Navigation drawer: branded header, grouped View switcher (active view
highlighted via secondaryContainer), filter list restyled to grouped rows with a
trailing checkbox; the whole drawer now scrolls as one.
Cards use surfaceContainerHigh for readable contrast against surface. Version
bumped to 2.3.0 / 20300. UI-only; unit tests green.

Day/week: tap an empty slot to open the create form prefilled with that
day and the tapped hour (snapped to the hour, 1 h long). Threaded a start
time through CalendarHost → EventEditScreen → openNew; the FAB keeps its
default.
Local calendars: a full-screen editor from Settings → Calendars to
create/rename/recolor/delete device-only calendars (ACCOUNT_TYPE_LOCAL,
sync-adapter insert) with name, pastel-previewed colour, and a description
(stored in CAL_SYNC1). Synced calendars are listed read-only grouped by
account, each with a "manage in source app" deep-link resolved from the
account's own authenticator (DAVx5/ICSx5/…), plus an add-account shortcut;
a <queries> block makes the source apps launchable. Extracted a shared
InlineTextField into ui.common so the event form and calendar editor share
one borderless input style.
Tests: repository delegation + write-failure, mapper isLocal/description,
fake data source extended. Version bumped to 2.2.0 / 20200.

Replace the per-day dot summary with an event-rich grid. The ViewModel now
splits the grid into week rows and, per row, resolves all-day/multi-day
events into spanning bars (reusing the week view's layoutAllDay lane math)
and single-day timed events into per-day pills.
The grid renders as an overlay: each day gets a rounded surfaceContainer
background (matching the week/day views), spanning bars draw on top so a
multi-day event is one connected bar bridging the cells it covers, and
single-day pills fill the lane slots no bar occupies on that specific day
(top-most first) so a bar-free day isn't pushed down. Up to three rows
show per day, then a "+N" dot row. Today is a filled circle on its number;
neighbour-month days are dimmed.

The slide-out panel gains a "View" section mirroring the top-bar switcher
pill: three NavigationDrawerItems (Month/Week/Day) with the current view
highlighted; tapping one selects that view and closes the drawer. The pill
stays as-is for quick cycling.
Centralise each view's label + icon as labelRes/icon extensions on
CalendarView so the pill and the drawer share one mapping. The drawer's
"Today" jump is dropped — the top-bar Today action and error-state retry
still cover it.

The event form's state pipeline ran .flowOn(io) over the whole combine,
including the _form round-trip every keystroke depends on. That async hop
handed BasicTextField a lagging value while typing, so Compose kept
correcting the cursor to the stale position.
Scope flowOn(io) to just the calendar/prefs/settings reads and collect the
form -> state -> UI path on the main dispatcher, so keystrokes round-trip
synchronously and the cursor stays put.

No locking (plan 03, decision 5): openForEdit keeps an EditSnapshot — the
prefilled form plus the raw Events-row times, which the form itself can't
see (it derives its times from the tapped occurrence, so an externally
moved event would otherwise stay invisible). Right before writing,
performSave re-reads the event and compares snapshots: a mismatch parks
the save in SaveUiState.AwaitingConflict carrying the already-chosen
recurring scope, and the dialog offers overwrite / discard / cancel
(OptionCard style). Overwrite still writes only dirty fields, so external
changes to untouched fields survive either way. A deleted event lands in
SaveUiState.Gone — an informational dialog that closes form and detail.
Fields the form can't write (attendees, status, self response, reminder
methods) are excluded from the comparison so sync noise can't fake a
conflict. The load-time zone is pinned in the EditTarget so a device
timezone change mid-edit can't either.
Store metadata: F-Droid descriptions (DE+EN) and the README stop claiming
read-only and now describe write support and reminder delivery. New
fastlane phoneScreenshots (6 per locale: week/month/day/detail/form/
reminder onboarding), captured on-device against demo-only calendars.
Tests: EditSnapshot equality (unchanged event, field change, row-time move
the form can't see, non-writable changes stay quiet).

Calendula now posts event reminders itself (the Etar model): the provider
schedules the alarms and broadcasts EVENT_REMINDER, but a calendar app must
turn them into visible notifications — essential for users whose only
calendar app this is. A manifest-registered, exported receiver (data scheme
content://com.android.calendar) wakes us at reminder time; no foreground
service, no own alarm scheduling.
Delivery path (data/reminders/): EventReminderReceiver (Hilt, goAsync) →
ReminderAlertStore queries CalendarAlerts for STATE_SCHEDULED rows with
ALARM_TIME <= now → ReminderNotifier posts one notification per alert on a
dedicated high-importance channel, then best-effort marks rows FIRED
(needs WRITE_CALENDAR; without it a re-broadcast silently replaces — tag
per alert + setOnlyAlertOnce). Swiped notifications never return: FIRED
rows are never re-queried, so no dismiss-intent machinery. Research
(AOSP CalendarAlarmManager): the provider creates alert rows only for
METHOD_ALERT reminders, so the email-reminder filter happens upstream.
Tapping opens the event's detail screen: MainActivity is singleTop now,
parses eventId/begin/end extras (onCreate + onNewIntent) into Compose
state, and CalendarHost consumes the key exactly like an event tap.
Onboarding gained a one-time second step after the calendar grant (shared
OnboardingScaffold extracted from PermissionScreen): explains delivery,
warns that a second calendar app with notifications on duplicates
reminders, requests POST_NOTIFICATIONS (dialog on API 33+ only; minSdk 29).
"Not now" turns the feature off; reminders default ON. Settings mirrors
the toggle in a new Notifications section with the duplicate hint, and
re-requests the permission when enabling. Strings DE+EN.
Deliberately deferred (roadmap): snooze/dismiss actions, BOOT_COMPLETED /
exact-alarm scheduling, battery-exemption prompts.
Tests: reminderTimeText (all-day UTC-midnight reading, exclusive end day,
midnight-crossing ranges), reminders/onboarding pref round-trips.

The create form (v1.2) now edits: a pencil on the detail screen (writable
calendars only, contextual WRITE upgrade like delete) opens it prefilled via
EventDetail.toEditForm; populated sections always show, the calendar is
fixed, and a dirty-check writes only changed columns (pristine saves are
no-ops). Saving a dirty recurring event parks in SaveUiState.AwaitingScope
and asks how far the change reaches (Google model): "only this event" =
modified-occurrence exception via CONTENT_EXCEPTION_URI (empty optionals as
explicit NULLs since the provider clones the parent row), "this and all
following" = series split (insert new event first, then truncate), "all
events" = series-row update with the time delta applied to the series
DTSTART. A changed rule drops the exception option. Delete gained the same
middle scope.
Recurrence: EventForm.rrule + SimpleRecurrence (FREQ/INTERVAL/UNTIL/COUNT +
weekly BYDAY with locale-ordered weekday toggles) behind a picker on create
and edit; unrepresentable rules render humanized (shared ui/common
RecurrenceText) and survive verbatim. UNTIL validation flags rules ending
before the event starts.
Provider lessons baked in (verified on-device via adb probes): instance
caches regenerate only from an update's own values, so truncation sends the
full time-column set (truncateSeries) — RRULE-only updates left a stale
duplicate occurrence on the split day; UNTIL is written as the local end of
day in UTC (toRRule(zone), previousLocalDayEndUtcMillis) so UTC+x zones
can't leak an extra day. Reminder edits reconcile against actual provider
rows, keeping untouched rows' methods.
Tests: RecurrenceTest (parse/render/round-trip, truncation), update/exception
mapper paths, repository pass-throughs, prefill + populatedFields, raw-title
mapper.

Post-v1.2.0 design iteration on the event form, reviewed slice by slice
on-device:
- Form rebuilt on the detail screen's card system: tonal EditCards with
gutter icons (centred on the first row, top-aligned for multiline),
borderless inline fields (placeholders at half opacity), calendar-coloured
title accent, no dividers, bare top bar
- Optional sections (location, description, reminders, availability,
visibility) with per-user defaults in Settings ("New event form" toggles);
hidden ones unfold via a "More fields" picker dialog
- Reminders: stacked rows + full-width borderless add; two-step picker
(one-tap presets, then custom amount + minutes/hours/days/weeks dropdown);
written as METHOD_ALERT Reminders rows. Availability busy/free segmented
toggle; visibility selector with per-level icons
- OptionCard (ui/common) is now the app-wide selection-dialog standard;
calendar picker, visibility, more-fields, reminder presets and the
recurring-delete chooser all use it — radio-row dialogs removed
- MaterialExpressiveTheme with MotionScheme.standard() (expressive bounce
felt overdone); FAB stack + field reveals animate on theme springs;
jump-to-today slides toward today's actual direction
- IME: adjustResize + imePadding so the keyboard never pans the form
- Tests: form-field prefs round-trips, availability/access provider
mappings; DE+EN strings throughout

Second slice of milestone 2 (write support):
- EventForm domain model + problems() validation (end-before-start,
no-calendar; blank titles and instant events stay legal)
- Full-screen EventEditScreen: title, all-day switch, M3 date/time pickers
(moving the start preserves the duration), calendar picker limited to
writable calendars, location, description. Save validates, requests the
WRITE upgrade contextually, and closes on success
- Calendar preselection: explicit pick > last-used (CalendarPrefs) > first
writable calendar
- insertEvent in the data source; EventWriteMapper (JVM-tested) normalises
all-day events to UTC midnights with exclusive DTEND, timed events to the
device zone
- CalendarFabColumn shared by month/week/day: persistent "+" FAB anchored on
the visible day, jump-to-today pill stacked above it
- Tests: EventForm validation, write-time mapping (incl. DST-safe epoch
check), repository createEvent delegation/error propagation

First slice of milestone 2 (write support), per the new plan in
docs/superpowers/plans/2026-06-11-03-write-support.md:
- Delete from the event detail screen with confirmation; recurring events
choose "only this event" (cancelled exception via CONTENT_EXCEPTION_URI,
series survives) or "all events in the series" (Events-row delete)
- WRITE_CALENDAR in the manifest; onboarding requests read+write in one
system dialog but only read gates the app — declining write keeps it
usable read-only. v1.0 installs get a contextual write request on their
first delete
- CALENDAR_ACCESS_LEVEL is read into CalendarSource.canModifyContents;
read-only calendars (WebCal, birthdays, …) show no write actions. The
no-op placeholder Edit button is removed until edit ships (v1.3)
- Onboarding copy drops the now-false "read-only" claim (DE+EN)
- Tests: repository delete delegation/error propagation, access-level
mapping; FakeCalendarDataSource grows write ops

The onboarding screen is the first thing a new user sees; it was a bare
centred title + body + button. Rebuild it as a proper Material 3 Expressive
welcome:
- Branded hero reconstructing the launcher mark (slate squircle + foreground
vector); the denied state adds a lock badge over the corner
- App-name eyebrow, a benefit-led headline, and three trust rows (stays on
device / every calendar together / no tracking) with tonal icon chips
- Full-width filled CTA with a trailing arrow, pinned in a Scaffold bottom bar
clear of the navigation bar; scrollable body for short screens
- "Read-only · no internet permission" footnote — accurate: the app declares
only READ_CALENDAR
- Denied/recovery state reuses the same shell with Open-settings (primary) and
Try-again (text) actions
- 8dp spacing scale, edge-to-edge insets handled via Scaffold
Built with the newly installed material-3 skill's token/component guidance.
Resolves the pre-1.0 polish backlog item.

The Busy availability value is the default for nearly every event, so a
"Busy" chip on every detail screen was noise. Show the pill only for Free
(the noteworthy case) and move it to the top-right of the title row instead
of the under-title chip strip. That strip now carries only status/access and
hides entirely when there's nothing noteworthy. Drops the now-unused
event_availability_busy string from both locales.

Round out the read-only model so the detail view shows everything
CalendarContract actually stores, ahead of write support.
Data layer:
- New domain types: Reminder, EventStatus, Availability, AccessLevel,
AttendeeRelationship, AttendeeType; EventDetail gains reminders, status,
availability, accessLevel, eventTimezone, selfStatus and Attendee gains
relationship + type (all defaulted so existing callers compile)
- EventDetailProjection reads STATUS / AVAILABILITY / ACCESS_LEVEL /
EVENT_TIMEZONE / SELF_ATTENDEE_STATUS; AttendeeProjection reads
RELATIONSHIP + TYPE; new ReminderProjection queries CalendarContract.Reminders
- Mappers translate each provider integer code, guarding STATUS's null-vs-0
ambiguity (0 == TENTATIVE) so an absent status reads as Confirmed
- Mapper unit tests cover every new column's codes
Detail UI:
- Status / availability / access chips under the title; cancelled also strikes
the title through
- Reminders card with humanised lead times (plurals, DE + EN)
- Foreign-timezone card, shown only for timed events in a non-device zone
- Attendee role badges + the user's own "Your response: …" line
- http(s) URLs in the description are now tappable
URL field cut: CalendarContract exposes no Events.URL column (only the
CUSTOM_APP_URI app deep-link), so URLs are surfaced by linkifying the
description instead. Recorded in ROADMAP/CHANGELOG.
Version bumped to 0.6.0 / 6.

M3 — calendar filter: the navigation drawer now hosts the calendar list
inline (grouped by account, colour swatch + checkbox per calendar). Hidden
calendars are persisted app-side and filtered centrally in the repository,
so month/week/day re-filter live the moment a checkbox flips. Drawer trimmed
to Today, the calendar filter, and Settings, with leading icons and a clear
title/section type scale; the stubbed jump-to-date entry (M2) was removed.
M4 — settings: full-screen destination with appearance (theme System/Light/
Dark, Material You dynamic colour auto-disabled < API 31, week start Auto/Mon/
Sun), language (per-app locales via AppCompat, persisted to API 29), and an
about section (version, licence, source link). Theme is driven by one
activity-scoped settings source so changes apply app-wide at once. Week start
now drives the month grid and week view; Auto follows the locale.
Also:
- default view switched from month to week
- Settings screen handles system back (was closing the app)
- fix pre-existing NonObservableLocale/LocalContextConfigurationRead lint
errors in EventDetailScreen so CI lint is green again
- versionName/versionCode bumped to 0.5.0 / 5
Tests: repository hidden-filter (incl. live re-emit), SettingsPrefs round-trip
+ week-start resolution, filter grouping. lint + unit tests + assembleDebug green.

Tapping an event in the week/day timeline opens a full-screen detail
destination (MD3 list→detail, not a bottom sheet) overlaying the calendar
with a slide transition. One card per field (when, calendar, location,
description, attendees, recurrence) with leading icons; location taps open
a maps intent. Loading/Failure/Success throughout.
Recurrence is humanized from the RRULE — e.g. "Every week on Tue and Thu
until 31 Dec 2026" — covering FREQ/INTERVAL/BYDAY/UNTIL/COUNT with
abbreviated, italicised day names and localized list formatting, falling
back to a generic label for rules it can't render.
Also:
- fix: recurring events failed to open (series row stores DURATION, not
DTEND, so the mapper dropped them as EventNotFound). The detail keeps
them and shows the tapped occurrence's own times from Instances.
- feat: month day cell → opens the day view anchored to that date.
- build: add material-icons-extended (R8 strips unused icons in release).

Day view as a one-column slice of the week view: shared TimedBlock/
AllDaySpan layout, per-day swipe navigation, hoisted noon-centred scroll,
animated all-day strip, and a compact top bar showing the full date.
- DayUiState / DayViewModel / DayScreen under ui/day
- reuse layoutDay/layoutAllDay/coversDay from the week package
- add Day to IMPLEMENTED_VIEWS; CalendarHost routes it explicitly
- day_today_action strings (en/de)

- Rounded, permanently-soft day-column scroll viewport via two viewports
sharing one scroll state (gutter + columns stay aligned); plain
rectangular column cards inside
- Vertical scroll position now persists across week swipes; noon-centring
only runs on first entry into the week view (from month/day)
- All-day strip height is hoisted + animated, shared by both swipe pages,
so it slides along and resizes smoothly instead of jumping
- Multi-line event time label so the end time isn't clipped in narrow
columns; hour labels centred in the gutter
- Calendar-week (ISO) badge in the header gutter, aligned with the date
numbers; dropped the redundant "All-day" gutter label
- Small breathing room between the top section and the timeline

Replace the throwaway debug screen with the first real calendar UI and a
functional Month <-> Week switcher, on Material 3 Expressive.
Month view (S1):
- Material 3 Expressive card-per-day grid; only the current month's weeks
render (neighbouring days left blank)
- per-day event dots with "+N" overflow, today via primaryContainer
- spring-based press feedback from the active motion scheme
- swipe + drawer navigation, Loading/Failure/Success states
Week view (S2):
- vertical time schedule with overlap-resolved lanes (per-day clipping,
midnight spanning, instant events)
- all-day / multi-day events as connected horizontal spans
- single scroll container (gutter + day columns stay aligned), columns
bundled in a rounded container, noon-centred on load
- top section colour-shifts with the app bar on scroll; swipe navigation,
three states
Shared / infra:
- CalendarHost holds the active view; RootScreen renders it post-permission
- ui/common building blocks: CalendarDrawer, CalendarFailure,
ViewSwitcherPill, pastelize, observable locale, M3 Expressive slide
transition (motionScheme fastSpatialSpec)
- unit tests for the week layout (lanes, clipping, all-day spans)
- build: compileSdk 37, material3 pinned to 1.5.0-alpha21 for Expressive

Cal.id and Event.instanceId share a numeric range, and the LazyColumn
keys both sections — colliding values (e.g. cal-id=4 + event-instance-id=4)
crashed with "Key '4' was already used". Additionally, Instances._ID is
inherited from the parent Event, so recurring events produce multiple
rows with the same instanceId; the start instant disambiguates them.
Replaces the simple numeral-only foreground from v0.1.0. The new mark
keeps the kalendae reference explicit (a bold "1" inside the
calendar body) and adds a small calendula bloom as a badge in the
bottom-right corner so the app's "calendula" brand reads at first
glance.
- design/icon/calendula_mark.svg: source SVG (232x232 viewport,
monochrome, lawnicons-style strokes 12/8)
- app/src/main/res/drawable/ic_launcher_foreground.xml: regenerated
as a VectorDrawable preserving the source path data. Off-white
(#FAF6F0) strokes on the existing slate background. Reused as the
<monochrome> slot so Android 13+ themed-icon launchers can recolor
it from wallpaper.
- fdroid-metadata/.../{en-US,de-DE}/icon.png: 512x512 PNG composed
from the same source SVG with the slate background baked in, so
F-Droid clients show a fully rendered tile in the app catalog.

Deviation from Plan 02: changing from Cursor-returning interface to
domain-returning interface so the repository unit tests can use a simple
fake without constructing ContentObserver/Handler/Looper on the JVM
(which would either crash or no-op via the mockable.jar stubs).
Deviation from Plan 02: the JVM mockable-android.jar stubs every Cursor
method even with isReturnDefaultValues=true (returns null/0 regardless of
the underlying MatrixCursor backing). Introduce an internal ColumnReader
interface so mappers stay pure-Kotlin and JVM-testable via MapColumnReader,
while production reads through CursorColumnReader.
