Writing
Four pieces, each one written up from a decision I actually made and can point at the code for. Evaluation loops, why this site has no database, why a blocklist fails open, and the difference between a check that retrieves and a check that answers.
- 2026-08-26A system that never learns whether it was rightThree systems built around one sentence, none of which I ever called evaluation: a settlement loop, a check that fails the build, and an app that refuses to answer.7 min
- 2026-08-24The sentence that killed the databaseI designed this site's retrieval around Postgres with pgvector, then deleted it before it existed. One sentence did it.5 min
