Class group (1024-bit prime discriminant from the checkpoint hash, chiavdf
construction, NUDUPL/NUCOMP/Lehmer xgcd ported from vendor/chiavdf) and an
RSA-2048 trusted-setup stand-in for timing. eval, block prover, verify,
epoch_seed/verify_epoch_seed, grinding model, README with measurements and
the parameter recommendation, bench-log entry.
M5 Max: class 163k sq/s (T 98 M for 10 min, 588 M for 1 h), verify 4.5 ms,
proof 516 bytes; full 10-min runs for both groups; grinding gain for a 30%
miner +3.62 blocks/epoch with no delay, 0 with it.

proto-metal: default dataset is now the memory-hard construction (MEMHARD.md), --closed-form keeps the original.
Cache fill 2 ms GPU / 185 ms one CPU core; dataset build 20.6 ms; GPU cache == CPU cache on all 2^26 words.
Shortcut ratio: inline kernel 111x faster than honest (closed form) to 4.8x slower (memory-hard), 1 GiB.
CPU verify 0.63 to 0.80 ms per warp at 104 loads, 1.21 ms at 144 loads (4,608 items): 10 ms gate met.
Levers --load-weight and --wide-frac implemented and measured, both off; default generator unchanged.
Fuzz 200/200, edge, determinism, memcheck, stats re-run on the new dataset, all PASS.
proto-cuda: host.cu handles both dataset modes; new pack igneum-genesis-mh with memhard.h; clang emulation PASS
including the three-way cache check. Old packs unchanged; closed-form export is byte-identical to them.
docs/bench-log.md: dated summary.
Note: a concurrent session running git commit -a swept earlier states of these files into its site commits
(7b28d5e through d6539fa); this commit carries the remainder.
