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.

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.

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.

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.

README gains a real install path: add the self-hosted repo
(apps.dev.jeanlucmakiola.de/dev/fdroid/repo, fingerprint inline and as an
add-repo link), search, install. Verified live against the repo index.
Roadmap gains the approved daily-driver idea backlog (unscheduled): slot-tap
create, drag & drop rescheduling, agenda view, pinch-zoom, reminder
snooze/dismiss + default reminder, duplicate event, per-event color,
.ics share/receive, app shortcuts, jump-to-date — plus the consciously
rejected list (network-dependent features, NL quick entry).

Captured from discussion, deliberately undetailed: permission-free contact
address picker, Photon-based address autocomplete (would need INTERNET —
explicit go/no-go on the no-network promise before any work), inline
contact suggestions, attendee editing as its own future milestone.

Version bumped to 2.0.0 / 13. No code changes beyond the version — 2.0.0
closes out Milestone 2 (write support, v1.1 through v2.0): the final slice
is the save-conflict dialog (external change → overwrite/discard, external
delete → informational close), plus the store refresh: descriptions and
README describe write support and reminders, and fastlane screenshots
(DE+EN, six each) ship for F-Droid. CHANGELOG [2.0.0] carries the details.
Quick-add was cut from scope (the prefilled form covers it); calendar
switching while editing moved to the v3 backlog. Both documented in the
roadmap.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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).

Version bumped to 1.4.0 / 12. No code changes beyond the version — 1.4.0 is
the reviewed-and-approved reminder slice: the EVENT_REMINDER receiver posting
due CalendarAlerts on a dedicated channel, tap-to-detail, the one-time
onboarding step requesting POST_NOTIFICATIONS with the duplicate-reminders
warning, and the Settings mirror. CHANGELOG [1.4.0] carries the details.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
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.

Version bumped to 1.2.1 / 10. No code changes beyond the version — 1.2.1 is
the reviewed-and-approved form polish: card design system, optional fields
with settings defaults, reworked reminders, OptionCard dialogs app-wide,
expressive theme on standard springs, direction-aware today jump, IME fix.
CHANGELOG [1.2.1] carries the details.

Version bumped to 1.1.0 / 8. No code changes beyond the version — 1.1.0 is

carries the details; ROADMAP/STATE mark slice v1.1 shipped.

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

Version bumped to 1.0.0 / 7. No code changes beyond the version — 1.0.0 is the
accumulated v0.1 → v0.6 work (all V1 screens, full event read, filter, settings,
onboarding polish) declared release-ready. CHANGELOG [1.0.0] summarises the
shipped feature set; ROADMAP/STATE mark V1 complete.

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.

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.

Plan to surface every readable CalendarContract field (reminders, status,
availability, attendee role + self-status, timezone, URL, access level) in
the detail view before write support. Recurrence-override badges and
CATEGORIES/ATTACH stay out (the former folds into v2, the latter is a
provider limitation). Noted only — implementation comes later.

The date-picker half of M2 is dropped entirely; the "Today" half already
shipped in v0.5. V1 is now feature-complete and only a polish/QA pass
remains before v1.0.
Updated the living planning docs (ROADMAP, STATE, REQUIREMENTS) and the
design spec; corrected the v0.5.0 CHANGELOG note that promised M2 would
return in v1.0.

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.

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

- ROADMAP: mark v0.1 (Foundation & CI) as complete
- REQUIREMENTS: move Foundation & CI from Active to Validated (shipped)
- AndroidManifest: drop redundant android:label and android:theme on
MainActivity - both inherited from <application>
- build.gradle.kts: move ui-tooling-preview to debugImplementation
(@Preview annotations are dev-only; release APK stays smaller)
All foundation verification (lint + test + assembleDebug) still green.
