 ## 20:51 the number-free public copy is applied on ca2-coord (0ad70ba and the next commit)
 
 site/litepaper.html: the Mining section's "bound by memory bandwidth" is corrected to "waits on memory latency, not on maths or bandwidth"; the "Everything above is automatic" paragraph is replaced by the level 2 three ideas and the fourth paragraph with a link to the numbers page; the vs RandomX rows "Changes over time" and "Dataset" and the Hardware paragraph carry the step schedule (years 4, 12, 28; 4 GB about four years, 8 GB about twelve). site/index.html: the Memory row and the Mine card carry the step schedule ("2 GB at genesis, doubling at years 4, 12 and 28"; "any 4 GB card at launch, 8 GB from year 4"). NOT yet applied, because they carry the chip number: the level 1 sentence in the hero and the abstract ("a custom chip gains under 2x") and the limits bullet "A chip is impossible"; they wait for the combined chip row from docs/analysis/chip-model-v3.md (if 1.8x: "under 2x" with the margin stated as thin; else qualified). The bench page's Counter ASIC section (level 3) waits for the final table. docs/evidence.md's card-lifetime row (designed) is still to add.

+## 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).
