+4. **Extract** (session end): The SessionEnd hook launches a background ingestion process that parses the transcript, runs the encoding gate on each fact, and stores high-quality memories. (On Claude Code, the `SessionEnd` event fires only when the session actually terminates — `Stop` fires per-turn and is therefore the wrong trigger for transcript-end extraction.)

 ## Background Processing
 - Memories are also extracted automatically from conversations via background processing.
-- The Stop hook captures the full transcript and runs deep extraction after sessions end.
+- The SessionEnd hook captures the full transcript and runs deep extraction when the session terminates.
 - You do NOT need to store everything manually — focus on in-conversation corrections and explicit preferences.
 - The background extractor handles: personal facts, preferences, decisions, temporal facts, and technical context.
