Radicale becomes a write-only render target, not a store. sqlite stays canonical: every poll mavcaldav reads the pending reminders out of core and publishes each one as a single-event iCal resource, withdrawing the ones that have fired or been cancelled. Losing the collection costs nothing — the next tick rebuilds it, and nothing is ever read back from it. It structurally cannot write to a calendar maven only reads. The render URL and credential are their own flags, and -render-url is refused at startup when it names the collection -url reads; the only paths it addresses carry the maven-reminder- prefix, so even aimed at the wrong collection it can only touch resources it created. Rendering is off unless -render-url is given. The calendar data model now lives in one place, internal/calendar: the Event, the iCal parse it comes from and the render it goes to, the fact key/value encoding, and the source constants that say which calendars may be written to. It was a parse inlined in cmd/mavcaldav and a Sprintf in two files; #126 and #128 both need to agree with it. Fixes a latent day-boundary bug moved out of that inline parse: it took the day number off a local clock reading but built the window boundaries in UTC, so on a box east of Greenwich part of the evening fell outside "today" and the poller saw an empty calendar after 20:00 UTC. Today is now the owner's day in the owner's location, which is what the busy gate and the day plan mean.
