## 20:51 the node builds every day cache through chain_dataset_day
ca2-v3 6c75dad (node agent): Epoch::chain_dataset_day(day_bytes, class, days_since_genesis, genesis_dataset_log2) with a placeholder body (the mixer branch fills growth_doublings under that signature), verify::days_since_genesis; the Metal worker takes v3 from a pack (compiled). Fork (uncommitted, in the cargo check holding build-1 since 20:50Z): Params::pow_genesis_dataset_log2 (28 on every network, in the digest in its own statement), Params::genesis_day_index(), install_pow_genesis in the daemon after the class switch, the engine's build_day through chain_dataset_day, the pack export through the same build_day, PowEpochInfo / RPC / proto fields 17 and 18 (genesis_day_index, genesis_dataset_log2; an old node's 0 reads as 28), override-60x.json and the redteam override carry pow_genesis_dataset_log2 28. Next: the check result, then "ready for PC 2" with the fork commit. evidence.md row 22 (card lifetime, designed) added on ca2-coord (3dc29fe).
## 20:53 spec text applied for the decided layers (ca2-coord 9b1f849)
docs/spec/01-lottery-hash.md: 1.12 carries epoch_len (the ladder 600 to 7,200, 90% signal at a day boundary, T_epoch and the lead fixed) with 3,600 unchanged on every network; 1.13.1 gains the mixer_mult row (4 under class v3) and the epoch_len row with the signal rule, the FPGA threat and the 600-s floor, and a pointer to era-layout.md for the layer 4 and 8 rows; 1.13.2 carries reserve family R1 = mm8 (uint8, W_new 4, unlock era 4 or 90% signal, the edge vectors, the native paths) and the emulation rule (8x per op, 5% hash-rate cap); 1.13.3 carries the cache growth rule (option C, growth_doublings(d) = floor(log2(1 + d / 1,460)), 256 / 512 / 1,024 MiB at genesis / year 4 / year 12, fill 0.2 / 0.4 / 0.8 s), the step mapping (b) as recommended, the shipped-density reason, and the cache freed after the daily build. docs/spec/04-seeds-and-vdf.md 4.3: the lead and T_epoch fixed at every epoch length. Still to land in the spec from the branches: 1.8.5 (the mixer x4 form, from mixer-x4.md), the 1.13.1 rows for stride, interleave and the window (era-layout.md), 1.5 and 1.8 for the hot table in the added form (hot-table.md), 1.17 and 1.15 for the v3 vectors and the conformance runs, 1.4.5 and 1.4.6 for generator 3 and the class in the pack.
