Project What it proves
HEOR Studio Study protocols in, machine-verified SAS + SQL out. 2,563 executed checks across 24 groups, 0 failing, mutation-tested. Refuses analyses it cannot compute honestly.
tableau-lineage.com Tableau Workbook Auditor: dead fields, duplicate calculations, performance lint, and lineage, fully client-side. 10.5K+ visitors in its first month.
Eigen-Rho AI-proctored technical assessments, graded against live Postgres execution instead of trusting the model.
ClipShuttle A YouTube-to-Premiere panel for a working video editor, built end-to-end with Claude Code (repo).

The through-line: I don't trust numbers I can't check. Everything above executes its own output against ground truth before showing it to anyone.
