Module availability 

Multi-stream availability merging with privacy-preserving output.

Accepts N event streams (from different calendars/providers), merges them into unified busy/free blocks within a time window. Supports privacy levels to control how much source information is exposed.

This module is the core of the “Unified Availability Graph” — it computes the single source of truth for a user’s availability across all their calendars.
