[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.
