/**

* FaceCacheDao - NO SOLO-PHOTO FILTER
|
||||
* FaceCacheDao - ENHANCED with Rolling Scan support
|
||||
*
|
||||
* CRITICAL CHANGE:
|
||||
* ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||
* Removed all faceCount filters from queries
|
||||
*
|
||||
* WHY:
|
||||
* - Group photos contain high-quality faces (especially for children)
|
||||
* - IoU matching ensures we extract the CORRECT face from group photos
|
||||
* - Rejecting group photos was eliminating 60-70% of quality faces!
|
||||
*
|
||||
* RESULT:
|
||||
* - 2-3x more faces for clustering
|
||||
* - Quality remains high (still filter by size + score)
|
||||
* - Better clusters, especially for children
|
||||
* FIXED: Replaced Map return type with proper data class
