@Service public class AgendaCalendarSubscriptionServiceImpl extends Object implements org.exoplatform.agenda.service.AgendaCalendarSubscriptionService
Holds every rule of calendar subscriptions (EXO-90278).

Stored events. A subscription fills a personal calendar of its own, flagged as a subscription, with one agenda event per occurrence of the feed in the window — so imported events appear in every view, the search and the preview like any other. They are written through AgendaEventStorage, never through AgendaEventService: no creation, update or deletion is broadcast, so nothing imported sends an invitation or a notification, computes a reminder, earns points, or reaches a connector's listeners; the search index is kept in step directly. The calendar flag is what makes them read-only (AgendaEventServiceImpl#canUpdateEvent) and what keeps the calendar out of the listings a connector binds remote collections from.

Reading a link. A link of this very eXo — its public domain and the path of a published calendar — is read in the process, through AgendaCalendarLinkService, with the token checks the anonymous feed applies; and refused when the calendar it publishes is one the user already sees. Every other link is read by CalendarFeedFetcher, whose guard decides which addresses the platform may reach.

Refreshing. A refresh is claimed in the database before it runs, by the scheduled job on every node and by the owner's "refresh now" alike, so a single node reads a feed at a time. It sends the validators of the last read, skips a body identical to the last one imported, rewrites only the occurrences that changed and removes those the feed dropped. A failure keeps the last good copy and records its message code.

Secrets. Feed URLs often embed one; a URL is stored encrypted with the platform codec, compared through a digest, returned to its owner only, and never logged.
