 **1. npm Changes Feed (every 2 minutes)**
 ```
-npm registry → /_changes endpoint → filter for tpmjs-tool keyword → process
+npm registry → /_changes endpoint → filter for tpmjs keyword → process
 ```
 This catches new packages and updates in near-real-time. We track sequence numbers so we never reprocess.
 
 **2. Keyword Search (every 15 minutes)**
 ```
-npm search "tpmjs-tool" → up to 250 results → validate → ingest
+npm search "tpmjs" → up to 250 results → validate → ingest
 ```
 Backup mechanism. Catches anything the changes feed missed.
