pastilhas 2bfdb9c284 say what this plugin is for, in the store's words
tags are how the marketplace is browsed rather than scrolled: a list of them on
the left, the plugins that carry one on the right. a closed vocabulary
(PLUGIN_TAGS in the platform) because free text becomes homelab, home-lab, Home
Lab and selfhosted inside a month, and a filter list of synonyms is worse than
no filter at all.

declared here rather than curated in the catalogue, so a plugin can say what it
is and nobody edits a table when one ships. the marketplace caches it on sync,
exactly as it already does for label and summary.

Calendar

Calendars and contacts on your own machine, synced to your phone over CalDAV and CardDAV.

  • Radicale, not a container. A ~2MB Python package, spawned on loopback by this plugin's sidecar. It was a Docker service only because the old app store made everything one.
  • Per user. The sync door resolves an app password to one account and tells Radicale that account's id is the principal; [rights] type = owner_only does the rest. Every user gets their own calendars and their own contacts, in their own directory, invisible to everyone else.
  • Phones work. DAVx5, iOS and Thunderbird, including RFC 6764 autodiscovery from a bare domain.

Two screens, one plugin

/calendar and /contacts. They are two places you go rather than two sections of one page, which is why this is the first plugin to declare screens in its manifest — one sidecar, one permission, one install, two routes and two dock tiles.

What it claims from the platform, and why

Four paths outside /api, above the account gate:

Path Why it cannot sit behind the session
/dav/* DAVx5, iOS and Thunderbird send HTTP Basic on every request and have nowhere to put a JWT
/dav/provision/*.mobileconfig Safari is handed a URL by the phone app and has no credential; the one-shot token in the path IS the authentication
/.well-known/caldav RFC 6764 — probed with a bare domain before the client has any credential
/.well-known/carddav the same, for contacts

"Above the account gate" is not "open". The sync door demands a scoped DAV app password and resolves it to a user before anything reaches Radicale.

Every one of those is in the platform's RESERVED_ROOT, claimable only by a first-party plugin. A third-party plugin is confined to /p/<publisher>/ so it can never shadow a core route.

Extracted from the platform on 2026-08-27

It was core from 2026-08-19. What moved: the sidecar, the four routers, the panel apps, the app-password table, and the settings form — which became a modal on the Calendar screen, because a plugin ships panels and cannot contribute a settings section.

Two things deliberately did not change. The table is still dav_app_passwords rather than caldav_app_passwords: installs already hold real rows, and the platform's prefix convention is not worth a data migration on a live machine. And the panel names still resolve through the platform's translation catalogs, so the six locales they had as core screens survive.
