- * @description Retrieves available staff for a time range
+ * @description Retrieves a list of available staff members for a specific time range and location
+ * @param {NextRequest} request - HTTP request with query parameters for location_id, start_time_utc, and end_time_utc
+ * @returns {NextResponse} JSON with available staff array, time range details, and count
+ * @example GET /api/availability/staff?location_id=...&start_time_utc=...&end_time_utc=...
+ * @audit BUSINESS RULE: Staff must be active, available for booking, and have no booking conflicts in the time range
+ * @audit SECURITY: Validates required query parameters before database call
+ * @audit Validate: Ensures start_time_utc is before end_time_utc and both are valid ISO8601 timestamps
+ * @audit PERFORMANCE: Uses RPC function 'get_available_staff' for optimized database query
+ * @audit AUDIT: Staff availability queries are logged for operational monitoring
