first two steps of docs/nextcloud-replacement.md — the half that has to work on
a phone, because that is the half that cannot be faked.
radicale is supervised by the sidecar rather than reimplemented. nextcloud does
not implement caldav either; it vendors sabre/dav. icalendar and vcard are a
weekend, but sync-collection, rrule expansion, vtimezone and ctag/etag are not,
and when they are subtly wrong a phone does not error — it silently stops
syncing, or silently duplicates every event.
two doors, because a browser should not speak dav:
/dav/* top-level, http basic against a scoped app password, every
verb and every dav header forwarded verbatim. this is what
davx5 and ios talk to. same reasoning as /api/vault being
mounted outside protectedRouter.
/api/caldav/* the ordinary sidecar proxy, for officer's own ui. json.
the shared proxy factory could not carry the dav door: it forwards three
headers and dav dies without Depth, and it derives the user from a jwt a phone
cannot hold. so it is a separate file, per that factory's own instruction never
to grow per-app logic.
new `dav_app_passwords` — a phone cannot do jwt, and the alternative is the
account password living in a phone's account manager. argon2, shown once,
revocable per device, and accepted ONLY by /dav.
.well-known/caldav and carddav redirect to the dav root. they are most of what
makes adding an account feel transparent, and they need naming explicitly in
server.tsx or the SPA `/*` fallback answers the phone with html.
verified end to end against the running stack: 401 + WWW-Authenticate
unauthenticated; 207 with calendar-access and addressbook advertised; MKCALENDAR,
PUT and GET of a real VEVENT; calendar-query and sync-collection REPORTs; MKCOL,
PUT and GET of a real vCard. X-Script-Name is set because radicale otherwise
generates hrefs at / and the client follows them into the SPA.
