 GATE ITEM (found by the era agent, two binaries on the same v2 input, checksum 19297e99c7b9a55e, same minute, load 4 to 5): the CPU verifier on ca2-v3 HEAD (88dafbc) takes 1.332 ms per warp and on the era branch 1.310, against readwidth's binary at 0.604 and 0.606: the mixer branch's derive_items / Shape path costs 2.2x at m = 1, on the v2 path the live devnet verifies with. The mixer agent's "loaded box" reading of its 1.31 to 1.36 ms v2 figure was the code, not the load. Ordered: find and fix on ca2-mixer, restore v2 to within 5% of 0.604 ms measured the same way, re-measure v2 / x4 / x8 on the fixed binary (the C19 figures too), then the node agent merges it; the publish waits on it (G3's suite does not catch a slowdown; the 10 ms gate and the pool and IBD figures depend on it). Next-cut rule: a verifier benchmark with a pinned bound in the crate's CI.
 
 PC 2 order: suite job 2 of 3 (kaspa-consensus alone, running), the proving agent's socket fix (60 s; the aggregation-cost restore is skipped), suite job 3 of 3 (the five other crates), the aggregation-cost re-run (20 min), the prover-floor agent's windows (through the proving agent). The proving app branch: a223ca9 is the last code change (8b47073 docs only after it).

+21:58. ca2-cache is rebased: one squashed commit 1950661 on ca2-v3 63dabb2 (fast-forwardable; history under tag ca2-cache-history-2026-10-05); V3_CLASS = { era: None, hot: None, ..MX4 }; every hunk kept the ca2-v3 side and appended the hot code; 53 + 19 tests; the pinned v2, mx4, era and readwidth packs untouched; the eight hot packs re-exported with unchanged vectors, 96/96 and the pre-rebase fingerprints on Metal and Apple OpenCL. The node agent merges it after the mixer's verifier fix.
