David debugged: Demanded a full memory retrieval trace after a wrong Project Bingo result

David challenged the memory architecture after a Project Bingo query retrieved unrelated Brightstar and Project Kristoff material. He explicitly rejected a quick fix that would narrow scopes or overfit to specific queries, and instead asked for the full technical path: how a user query reaches the local agent, how the agent calls the brain, how Turbopuffer, Graphiti, PageIndex, Docling, parsing, reranking, and evidence-pack generation participate, and how the original Dropbox data is transformed into memory along the way.

The work signal is the framing he imposed, not any architecture he accepted. He forced the debugging process to move from plausible explanation to actual traceability, separating positive signals (where Turbopuffer surfaced the right document) from negative signals (where the reranker promoted noise). That framing pushed the investigation toward log-driven evaluation instead of a cosmetic product answer.
