[SimoneMariaRomeo]

Summary

Null-result sweep for six additional high-rank score-1 developers not covered by the open #49 sweep. This records freshness without inferring a stance from silence.

2	Wladimir J. van der Laan	1	No quantum/PQC statements found
5	Michael Ford	1	No quantum/PQC statements found
12	Hennadii Stepanov	1	No quantum/PQC statements found
14	Alex Morcos	1	No personal quantum/PQC statements found
20	Eric Lombrozo	1	No quantum/PQC statements found
21	Johnson Lau	1	No quantum/PQC statements found

All scores and pq_work_volume values remain unchanged. Updated last_verified to 2026-05-13, appended update-history entries, and kept data.json / public/data.json byte-identical.

PC review — lekanbams

Approved.

• Null-result sweep, six score-1 maintainers (van der Laan, Ford, Stepanov, Morcos, Lombrozo, Lau). All scores and pq_work_volume held — records freshness without inferring stance from silence. Methodology mirrors the #37 / #49 precedent.
• last_verified: 2026-05-13, update-history appended, data.json / public/data.json byte-identical.
• Non-overlapping with #49's sweep set per the body.

Clean. Land after #42-style baseline is intact.
