The story

Built in a four-hour block at the Persistent Context Sprint at Pier 48 in San Francisco. Episodic interactions get compressed into durable facts on MongoDB Atlas, with contradiction arbitration and verbatim provenance so an agent can say where it learned something.

What I did

  • The consolidation pipeline and the Atlas schema, in Python, against the clock.
