makiolaj d5ce24b673 sync: report a refused resource instead of losing it
A multiget answer that was neither a body nor an omission fell through
every bucket: seen, so not missing; no body, so not a resource. Nothing
counted it, the sweep left it alone because the listing still named it,
and downloadPhase asked for it again on every sync for ever -- the loop
quarantine exists to break.

FetchResult now carries `failed`, with the status the server actually
gave. Kept apart from `missing` because "refused" and "not mentioned"
are different facts: 404 and 410 are skipped, since the next listing
drops the href and the sweep purges the row, and counting them would
quarantine the resource out of that very sweep; 5xx and a bodiless
success are skipped as the server's own trouble; any other 4xx is
counted, being a judgement about this resource that repeats forever.

A per-property refusal -- a propstat with 403 around calendar-data --
is the usual shape of "you may not read this one object", and
Response.properties drops non-2xx propstats, so the code is read back
out of them rather than reported as a blank.

The two write-side guards had to learn this too. Both read a fetch that
came back Result.success as an answer, so a refusal now looked like
"somebody else's resource" (a second resource under one UID) and like
"the server has no validator" (an unconditional PUT over a concurrent
edit) -- the two things those guards were added to prevent.

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.
