Rewrites the internal/db/queries comments to rule 32 and regenerates dbq, whose doc comments and embedded SQL carry them. The bugs behind the tiered mixes, the md5 order seed, the score bands and the round-robin arms are restated as the constraint each one enforces; counts from one library and stale cross-references are gone.
