- Verification over claims: every output on these pages was produced by an actual run, and key numbers were re-computed independently.
- Find → fix → re-verify: defects are documented with repro steps before fixing, then regression-checked.
- Honest methods: low-confidence findings (small samples) are flagged, not hidden; audit false positives are disclosed.
- AI-assisted, human-reviewed: where AI tooling accelerates work, the deliverable is always verified by me before delivery — happy to work human-only on request.
