makiolaj 83b4fb8e6e sync: do not write blind when the validator fetch fails
A row with an href but no usable ETag asks the server for one before
writing. That fetch was read with getOrNull(), so a timeout looked the
same as a server with no validator to offer: we PUT unconditionally over
whatever a concurrent edit had left there, and booked it under
unconditionalWrites, which by its own definition means the server had
none. The report asserted something false. Only Result.failure defers
now; a fetch that succeeds and yields nothing usable still writes and is
still counted.

The deferral also has to hold on the incremental path. downloadChanged
matches by href like downloadPhase does, so a row deferred mid-create --
still without an href -- is invisible to it and past its dirty-row
guard, and apply then matches by UID and overwrites the edit. The
explicit refetch list is filtered too.

deferred is set on both call sites of updateResource. It is redundant on
the direct one, where the row keeps its href, and load-bearing on the
adoption from createResource, where it does not.

Agendula

A modern Material 3 Expressive task app for Android.
Keeps your tasks on your device, or on top of a tasks provider you already use. Open standards, no account required.

CI Android 10+ Kotlin + Compose Material 3 Expressive MIT License

Agendula is the task-list sibling to Calendula. Where Calendula is a pure front-end over Android's CalendarContract, Agendula keeps its own store, designed around RFC 5545's VTODO — the same tasks DAVx5 (and SmoothSync, DecSync, …) sync out of your CalDAV server. It can also read and write a tasks provider you already have, for anyone already syncing that way.

The name rhymes with its sibling on purpose: Agendula is agenda — Latin for “things to be done” — given Calendula's -ula ending. Calendula keeps your days; Agendula keeps your to-dos. (A Calendula flower head is botanically a cluster of many small florets — so the two apps are florets of one bloom.)

Where your tasks live — your choice

Where Sync Needs
On your device (default) Agendula's own database none yet — CalDAV sync of our own is planned nothing. No account, no permissions, no other app
In a provider you already use OpenTasks or tasks.org whatever syncs it for you — DAVx5 and friends that app installed, and its read/write permission

Agendula's own store is an ordinary app database — nothing is published to other apps, so there is no authority to clash over and no permission to grant. It coexists with OpenTasks rather than replacing it: installing one never breaks the other, and if you already sync through a provider, that keeps working exactly as it did.

Recurring tasks are expanded per RFC 5545, and everything the schema does not model is round-tripped verbatim rather than dropped — so passing your tasks through Agendula does not quietly lose fields a server sent.

Your tasks are exportable as standard iCalendar .ics files at any time, because data you can't take with you isn't really yours.

Status: backend complete, UI catching up. Storage, reads and writes, smart-list filtering, a self-scheduled reminder engine, and export are built and unit-tested. The Material 3 Expressive screens are being built on top, one at a time — the storage-mode picker and export screen are not there yet. See docs/ROADMAP.md for status, docs/ARCHITECTURE.md for how it's built, and docs/STORAGE-AND-SYNC.md for why storage works the way it does.

Sync sources (by design)

In external-provider mode Agendula works with anything that writes to that provider — DAVx5 (CalDAV), SmoothSync, CalDAV-Sync, DecSync CC, or any Android sync adapter — because it builds on the provider, not on any one sync app. Google Tasks / Microsoft To Do are out of scope by design (proprietary; they would mean owning a sync stack). Open standards — CalDAV / iCalendar / DecSync — are the lane.

Translations

Agendula ships in English so far, and would like not to. Translations are managed on a self-hosted Weblate, and partial ones are fine — an untranslated string simply falls back to English.
