Ametller Origen 0.5.2

Fixes slow and fragile offline-ticket analysis by aggregating frequency and category leaders inside the local MCP server instead of returning hundreds of raw receipts.

The new summary=true mode scans up to 500 cached tickets, returns no raw receipts, and uses distinct purchase days as the primary regularity measure.
