makiolaj ddcffa61b3 sync: three corrections to the reconciler, from the review pass
The incremental path applied a page's removals before downloading its
changes, so a delete-and-recreate reported as removed one.ics + changed
two.ics purged the row before two.ics was ever fetched: the task came
back with sortOrder 0, no colour and no parent, and deletedLocally was
reported for a task nobody deleted. The same damage the sweep's
pre-download snapshot used to do, on the fast path. Bodies now go first,
after which the vacated href names nothing and the removal is the no-op
it should be — RFC 6578 reports each resource once, so a page cannot
both change and remove one href, and touched already guards what this
run wrote.

apply re-pointed a row's href in the hoisted index but left the old
entry naming those rows, so a later resource in the same batch read them
as displaced and deleted them: server holds two.ics with UID a (was at
one.ics) and one.ics now with UID b, and the rename is destroyed by the
resource that took its name. The in-memory twin of the same bug.

The download-side quarantine had no way back. At THRESHOLD the href is
stripped before the fetch, so apply — and with it succeeded — can never
run to clear the count, and a per-object ACL wrong for an afternoon hid
that task for the life of the install. The upload side is fine, since
stored and purge refund it there. The daily full reconciliation now
probes a quarantined href once: it costs one resource a day, and one
that answers clears its count.

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.
