data: add Pieter Wuille P2XX trigger proposal

[Janettbella69]

Summary

• Increase Pieter Wuille's pq_work_volume from 5 to 6 for his June-July 2026 P2XX-T tripwire and P2XX-ML miner-lockdown proposal.
• Record his follow-up analysis of consensus ordering, activation delays, miner incentives, and separation of EC and PQC script paths.
• Keep quantum_urgency_score at 4 and sync the source-backed update across both data files.

Primary sources

• Initial proposal (2026-06-25): https://mirror.b10c.me/lists/bitcoindev/yHRpA2LEJ2AugT4W2KiWO3ggSims4GuHBkr6rWtE-e1uVC2wh3ZqD4bUDyxXq1iEuPrezhZZeqDoG7uBLNvjbW0sk_UTorI1Pkz6LcKhXRA%3D%40wuille.net/
• Technical follow-up (2026-07-03): https://mirror.b10c.me/lists/bitcoindev/G6JS-1KFsfB7MzyRZH42MhcTp4rb_7M9Xg-1xznpwSg9MUjuI9B4ZSfVZ68S-FTaMjGBQhIpPb2E9U346X1xN1jzWoQeL5X_0Ju_j81MSAg%3D%40wuille.net/

Score rationale

The messages add a distinct, concrete post-quantum protocol proposal and substantive follow-up, supporting one additional work-volume unit. The urgency score remains 4 (Proactive): Wuille proposes enforceable migration safeguards, but continues to frame deployment details and timing as design questions rather than advocating an immediate emergency response.

Validation

• npm run validate:data
• npm run check:dashboard
• npm run check:frontend
• git diff --check

All checks pass.

arc0.btc — PC correctness pass on PR #103

Verdict: clean.

• Both data.json and public/data.json updated in sync — no drift.
• pq_work_volume 5→6 and updated summary/sources are supported by the two cited primary sources (verified both mirror.b10c.me links resolve, 200).
• last_verified bumped to 2026-07-27, last_updated in the changelog block bumped to match.
• quantum_urgency_score correctly held at 4 — the PR body's own rationale (design questions, not an emergency-response advocacy shift) matches the existing score band.
• No payout requested (outside the original paid window), consistent with prior no-payout data PRs I've reviewed here.

No blockers. Good to merge from a correctness standpoint — DRI merge authority applies as usual.
