My workbench for language, data & the record. Where I take words, names, places, the world's languages, prices, and the long memory of the open web — and turn them into things you can look at.
ragdiff: a small open-source tool that diffs two retriever configs per-query instead of scoring one in aggregate — because a metric that went up can still be hiding queries that got worse.
benchmarking graph-augmented retrieval against pure vector RAG for the "what should this student see next?" problem, and auditing my own numbers until they held.
