Objective

Prevent large address books and wide calendar ranges from slowing page open by making data windows explicit and paginated.

Context

The first performance slice removed an initial duplicate address contact fetch and parallelized calendar metadata loading. Remaining costs scale with data size:

Address book page fetches contacts with limit: 500 and should move toward explicit paging/search windows.
Calendar continuous mode can request a broad event range and should use clearer windows, deltas, and loading states.

Scope

Owning repositories: govoplan-addresses, govoplan-calendar, with core webui integration checks.
Add address contact pagination or virtualized window loading.
Add calendar range/window defaults that keep first paint fast while preserving useful continuous mode behavior.
Keep search and list membership workflows usable.

Checklist

Define address contact page size and UI behavior.
Add API cursor/offset support if current endpoint shape is insufficient.
Define calendar first-load event window and follow-up load behavior.
Verify large local datasets manually.

Verification Target

Core webui build.
Address and calendar API tests for page/window parameters.
Manual timing with large address/calendar datasets.
