step 3 of docs/nextcloud-replacement.md. collections, events and contacts as
plain json, so the browser never has to parse multistatus xml to draw a list.
this talks dav to radicale over loopback rather than reading its on-disk format.
the storage layout is radicale's private business and changes between versions;
propfind is its supported interface and costs one in-process hop. parsing the
storage directly would be faster and would break silently on upgrade, which is a
bad trade for a calendar.
three bugs found and fixed while verifying, all of which fail quietly rather
than loudly:
calendar-data and address-data are NOT webdav live properties. rfc 4791 and
6352 define them as report-only, and radicale correctly returns an empty prop
for them under propfind — so the first version returned a 207 full of nothing,
which reads exactly like "your calendar is empty".
the principal resource matched the calendar test, because `<C:calendar-home-set/>`
satisfies /calendar\b/. the principal showed up in the list as a calendar
called "1". the tag has to be required to end.
the internal fetcher omitted X-Script-Name, so the ui was handed /1/work/ for
the same collection a phone sees as /dav/1/work/, and nothing downstream could
have matched them up.
ical.ts is deliberately small: it unfolds lines and pulls out the fields a list
shows. it does NOT expand rrule or resolve vtimezone — radicale owns correctness
there, and rrule is passed through raw so the ui can say "repeats" without
either of us pretending to know when.
verified against the running stack with a real vevent and a real vcard, then the
fixtures were removed.

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.
