Neuer Router unter /api/local mit Upload, Liste, Download, Thumbnail und
Loeschen, dazu permissions.readable_local_event als fehlendes Gegenstueck
zu _writable_event.
Der Lese-Helfer prueft nicht nur den Kalender, sondern auch die
Privatsphaere: ein fremder privater Termin wird im Lesepfad maskiert, also
duerfen auch seine Anhaenge nicht ueber die UID erreichbar sein. Fremde
bekommen durchgaengig 404 statt 403, damit die Existenz nicht durchsickert.
Die Mengenbegrenzung zaehlt nach dem Insert innerhalb derselben
Transaktion -- zaehlen-dann-einfuegen waere ein Wettlauf, bei dem zwei
gleichzeitige Uploads beide 9 sehen.
Ausgeliefert wird immer als Download mit nosniff, nie inline. Dazu die
Capability-URL unter /api/attach/<token> fuer externe CalDAV-Clients,
abschaltbar ueber ATTACHMENT_PUBLIC_LINKS=0.

The recipient colour was stored on calendar_shares, so it only worked for
DIRECT shares. A calendar made visible through a group (a co-member's
group_visible_calendar_id) has no CalendarShare row, so the colour endpoint
returned 403 and nothing was saved — the reported "colour picker opens but the
colour stays the same" for a group-shared calendar.
Replace the share-scoped colour with a general per-user override table
(calendar_color_prefs, keyed by user+calendar). PUT /calendars/{id}/color now
accepts any calendar the user can read (readable_local_calendar_ids covers
direct shares, group calendars AND group-visible), and the merge read + calendar
list apply the override for all of them. Owners still set the shared colour.
The new table is created by create_all; the old calendar_shares.color is unused.

- Backend: co-member group_visible calendars now surface in /local/calendars
(owned=false, shared_by=owner, read-only, group_shared) and in the normal
/caldav/events merge (via readable_local_calendar_ids), deduped against
direct shares / group calendars so nothing appears twice.
- Backend: new User.directory_hidden — a user can hide from sharing/group
pickers (/users/directory), while admin user management (/users/) still lists
them. Migration + profile GET/PUT.
- Backend: /groups/{id} members carry shares_calendar so clients can drop
phantom rows for members who share nothing.
- Frontend: reachable "Teilen" button on owned local calendars; share modal is
now a checkbox multi-select of users (checked = shared). Hidden-profile toggle
in Settings → Profile. Group member filter only lists members who actually
share (phantom fix). Calendars shared with me moved to a dedicated read-only
"shared with me" section in the manage table.
- Tests: group_visible propagation, no-share absence, dedup, directory_hidden.
