PC 2 is free (the proving agent's last job closed; the live prover is back on). Proving fork tip ece42979 on 21d4c73c (N = 8, the digest test edit), app 440fd59 or later; its suites ride with the ca2 node suites on the merged tree; its harness on the final tree is running on the Mac. The S_p curve with the miner on the card (PC 2's 5090): empty shard 15,585 MiB 7.5 s; the adopted v1 shard (30,000 pgas, 4.7 M cycles) 22,210 MiB 13.2 s (20,435 MiB, 4.2 s alone); 2.25 M pgas 30,049 MiB 17.9 s; 4.5 M 29,954 MiB 26.3 s; the prototype shard 30,083 MiB 33.3 s. Tiers as the proving agent published them: 32 GB mines and proves today, 24 GB from the fee switch (2.3 GB spare on the adopted shard), 16 GB empty shards only, 12 GB nothing on this build (D2 to the project lead).
PC 2 queue: the ca2 node suites on the merged tree (ca2-v3-node + ece42979) as soon as the node agent sends "ready for PC 2"; nothing else is queued on PC 2.
## 20:57 the mixer construction is committed on ca2-v3's base
ca2-mixer 0fc0ad1 (rebased onto ca2-v3 6c75dad): LoadClass::MX4 = V3_CLASS (v2 loads, mixer x4, the growth rule; a class v3 program is the v2 program of its seed instruction for instruction, generator 3 in its id); chain_dataset_day has its real body (Shape::for_class_day: cache 2^cache_log2_words(d), dataset 2^dataset_log2_words(D_0, d)); 44 lib + 11 pack tests green, the two pinned v2 packs byte for byte. Next from it: --program-class v3 / --era-hex on the CLI, the pinned v3 packs mx4-genesis and mx4-devnet-epoch0 (era = the genesis-hash stand-in), the design and 1.8.5 spec text, the chip-model row; bit-exactness runs under the run lock now; the verifier and build timings wait for the measure lock (held by a live prover measurement from another worktree, pid 45000, 25 min in at 20:56). The node agent merges ca2-mixer before its fast-time gate, so the gate runs the real construction minus the era and hot fields.
