"""
Memory Digest — Identity-Query Fact Surfacing (Live)

Guards that the memory digest distiller (``enrichment.digest_memory_for_query``)
surfaces user-stated facts about the user (location, interests, ongoing
plans, biography) when the current query asks who the user is or what the
assistant knows about them, rather than surfacing past Q&A topics the user
merely asked about.

Motivating field incident:
  The user asked "what do you know about me?". The diary contained a
  user-stated fact ("goes boxing near E3 2WS") alongside a past Q&A where
  the user asked for the area of a rectangle. The digest surfaced the
  rectangle question, which is not a fact about the user at all — leading
  the reply model to miss the actual identity signal entirely.

General principle (encoded in the digest prompt): for identity queries,
user-stated facts dominate over past Q&A topics, and multiple such facts
should be surfaced when present.
