Merge Risk: 🟡 Moderate · up to Calendar drag-and-drop now writes task and meetup schedule changes directly to persistent storage. Because the current permission checks are client-side and independent backend authorization for these updates is not established, crafted requests could potentially reschedule records beyond intended permissions; merge should wait for server-side enforcement or explicit security-owner acceptance.

In `@src/app/shared/calendar.component.ts`:
- Line 374: Update both reschedule write flows calling
CouchService.updateDocument to start the loading indicator before subscribing
and finalize each observable with dialogsLoadingService.stop(). Ensure every
asynchronous write stops the indicator on success, error, or completion.
- Line 400: Update the drop delta calculation in the calendar event-drop handler
to use the persisted/original event start from eventData.startDate rather than
the potentially updated info.oldEvent.start. Ensure successive drops calculate
movement from the same persisted baseline before getMeetups() refreshes the
calendar.
- Line 410: Add a CouchDB validation rule for the meetups database that permits
updates only when the authenticated user matches oldDoc.createdBy or has the
administrator role, while ignoring any client-supplied createdBy value. Ensure
this rule covers the update path used by the calendar component’s updateDocument
call.

Authorization Bypass (CWE-862): Missing Authorization
Reachability: External · Exploitability: Moderate
Enforce reschedule authorization in CouchDB.
canEditMeetup protects only the browser UI. The repository has no validation rule for the meetups database. A non-creator can bypass the client check and submit a direct CouchDB update. Add a server-side rule that compares the authenticated user with oldDoc.createdBy or an administrator role. Do not trust the client-supplied createdBy.

Problem
PlanetCalendarComponent(src/app/shared/calendar.component.ts),editable: truewas hardcoded on all calendar event objects, allowing any user to drag and drop meetups or task deadlines to different dates on the calendar grid.calendarOptionslacked aneventDrophandler, the rescheduled dates were never persisted to CouchDB, causing events to snap back upon page refresh.Proposed Solution
