Retrieval-first engineering
Practical, source-conscious guidance on implementation memory, code provenance, proof receipts, MCP retrieval and the production primitives agents repeatedly get almost right.
What implementation memory is, how it differs from chat history and code search, and how coding agents can reuse proven patterns without losing provenance.
