+Once "0.3.17 live" (the hotfix) is read back: rebuild release-0.3.18-node on 12153428 plus the node lane's 4f4bb9c9 (ca3-v4-0317-fix: the idle-peer drop counts headers, proof, trusted data and UTXO chunks as deliveries and never fires during a sync; the class-signal missing-history warning once per epoch per process; kaspa-p2p-lib 20, kaspa-p2p-flows 35, class_signal 1 green on the box; the same patch onto ca3-v4-0318 by 05:15 UK), every platform, digests unchanged, suites, the integration check, the window test again on the merged tip; merge the UI lane's list (afc331bd in, then 74c12665, 89501ce8, b7d33e8e, the doc-only d29a8663), ember-tune-0317 c9b31edc; re-stage 0.3.18 in scratch; the fleet's full canary on its pods with the headers-proof fresh join decisive; publish 0.3.18 on its line, whenever that falls, morning included. Ember's PC 1 window ("PC 1 on 0.3.18") and the UI lane's Mac check follow its update-nows.
