the ai groups were retrospectives keyed to projects (pub-search's search, phi's memory, the marvin bot's history) — project notes belong in those repos. regrouped the way the content actually clusters: - ai/retrieval/ (was embeddings/): asymmetric embedding, reciprocal rank fusion, synthesize-before-injecting — query-time mechanics, projects as evidence within - ai/memory/ (dissolves persistent-agents/): message-archives (the transcript layer across marvin's three eras + phi's network-as-archive) and deliberate-and-background-writes (the two write paths, phi/letta convergence, write-time curation, the integration-surface lesson) - ai/cluster-the-2d-projection: loose note until a second cartography note earns a group - agentic-harness -> harness-weight: the finding is the page, Pi is the evidence - databases/ -> storage/ (redis was already stretching 'database'); turbopuffer-in-production moves in as storage/turbopuffer.md — vector store operations are storage operations Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
