The calendar feed emitted every task as a VTODO and, on top of that, an event only
for tasks that carried a clock time. But a subscribed calendar in Apple Calendar or
Google ignores VTODO entirely and draws only events — so a task with just a due
date, which is most of them, appeared in the verdande app's own calendar and
nowhere in the calendar it had been subscribed into. "Verdande does not update in my
calendar, only in the verdande app."
Every dated, unfinished task is an event now: a clock time makes a timed event as
before, a bare date an all-day one (a DATE start and an exclusive next-day end, so
it stays on its own day). Finished tasks stay off the calendar, as they were.
Test updated: the sample's timed task and its two date-only tasks all become events
now, the all-day ones in the DATE form, and the finished one still makes none.

Bedt om som "abonnering af flere kalendere (ics og webcal?)". Det er også den
eneste vej for en privat konto: instansens OAuth-klient er Internal, og Google
afviser en konto udefra med `org_internal`, uanset hvad der ellers er sat op.
**Samme tabeller.** Et abonnement er én kalender med begivenheder i, og det er
præcis det, `calendars` og `calendar_events` allerede beskriver — med vinduet,
farven, `shown` og hele fejemaskinen omkring sig. En tabel til ville være en anden
vej til det samme sted, og to veje til ét sted er to steder at rette den dag noget
om begivenheder ændrer sig.
Det, der skulle laves om, var identiteten. En OAuth-konto er én pr. person og
udbyder — tokenet er identiteten — mens et abonnement er én pr. adresse, og man har
flere. `calendar_accounts_once` er derfor delvist nu: det holder for rækkerne uden
adresse, og et andet indeks holder adresserne unikke. Delvise indekser er den ene
ting, SQLite kan her, som ellers krævede en tabelombygning.
**`webcal://` skrives om til `https://`.** Det er ikke en protokol, noget taler —
det er en konvention, der får et skrivebord til at give adressen til
kalenderprogrammet i stedet for til browseren, og alle udgivere skriver deres links
sådan. At afvise den ville være at afvise folk på en teknikalitet.
**Adressen gennem `safedial`, begge halvdele.** Afvist hvor den skrives ned, så
den, der står med feltet, får svaret med det samme — og igen på den *opslåede*
adresse hver gang den hentes, fordi et navn, der blev godkendt ved indtastningen,
kan svare 127.0.0.1, når fejemaskinen kører klokken tre om natten. Det er den
sætning, `internal/safedial` selv står og advarer om, og den blev skrevet efter et
SSRF-fund i morges.
**Hentet én gang, før den gemmes.** En adresse, der ikke kan læses, er en tastefejl
langt oftere end en server, der tilfældigvis er nede, og at sige det, mens nogen
står med feltet, er de to sekunder værd. Et abonnement, der lydløst aldrig fyldes,
er den samme tavshed, notifikationerne havde.
Læseren er ny i `internal/ics`, som hidtil kun kunne skrive. To ting, den med vilje
ikke gør, står skrevet ved den: den udfolder ikke gentagelser, og den opløser ikke
tidszoner. Begge dele er større end de ser ud, og begge har ét sted at høre til
den dag de skal.
En ting, formatet lærte: DTEND er eksklusiv for en heldagsbegivenhed. Gemmes den,
som filen skriver den, dækker hver eneste helligdag også dagen efter sig.
Én adresse, der fejler, stopper ikke de andre. Et abonnement er en anden persons
server, og den ordinære tilstand for en anden persons server er, at den er i orden
indtil en morgen hvor den ikke er.

The MCP server speaks JSON-RPC over Streamable HTTP with the six tools
the brief names, authenticated by a personal API token — so a connector
reaches exactly what its owner reaches and there is no second identity
to reason about. A failed tool call returns a tool error, not a protocol
error: a model can recover from the first and can do nothing with the
second.
CalDAV serves VTODO, two-way, so Apple Reminders and Thunderbird can
read, create and complete tasks. Clients authenticate with Basic using
an API token as the password, never the account password — a client
stores what it is given, and what it is given should not be able to sign
in to the app. Completed tasks stay in the collection: a client that
stops seeing one treats it as deleted and drops its own record of having
done it.
The AI layer is one interface with adapters for Anthropic, OpenAI,
Google and any OpenAI-compatible endpoint. That last one is why the
abstraction exists: an integration that only spoke to a hosted API would
be useless to somebody running their own models. Every feature degrades
to "off" when nothing is configured, and the stored API key is never
returned to the settings page.

Reminders are absolute or relative ("10 minutes before"). A relative one
is resolved against the task in SQL, so moving a task moves its reminders
too. They are marked sent before delivery, not after: a reminder that
goes out unrecorded repeats every minute forever, which is worse than
one recorded that fails to send.
The calendar feed is a per-user token in the path, because Apple Calendar
and Google fetch with no credentials and no way to prompt for any. Tasks
go out as VTODO — the same component CalDAV will serve — and timed ones
also as VEVENT, since Google ignores VTODO entirely.
Templates store relative day offsets rather than dates, which is what
makes them reusable: an onboarding checklist is "day 1, day 3, day 14",
not three dates in March. Building a project from one is a single
transaction, so a failure cannot leave half a checklist.
Backups use SQLite's VACUUM INTO, not a file copy — a copy of a live
WAL database can miss recent writes or catch a page mid-update, and the
result looks like a database right up until it is needed. Rotation keeps
fourteen by count, not by age: a container that was off for a month must
not come back and delete every backup it has.
