The chain animation scales its proving tempo to the canvas width, so a block is mined, proven and locked before it leaves a phone screen. Opening frame seeds proven and locked blocks on narrow canvases too. Repository links point at github.com/igneum-network/igneum.

Standard-library Rust port of the Swift prototype for the rusty-kaspa fork. 23 tests
tie it to proto-cuda/packs: program.json instruction by instruction for three packs,
cache FNV 48c4f5bf24166b2e, dataset head/last/64 samples, 96/96 hash vectors per pack,
and kernel.cu, program.metal, kernel.cl, program.h, memhard.h, memhard.metal byte-identical.
CPU verify 0.41 to 0.58 ms per warp (Swift 0.63 to 1.21), cache fill 175 to 181 ms one core.
CLI: bench, export, hash. program.json is written as valid JSON (the Swift quotes the
cache line mask inside the "item" string; fix pending in main.swift).

Exporter writes kernel.cl next to kernel.cu (same instruction list; memory-hard core emitted in a third, OpenCL C
dialect with the same literals as memhard.h). Pack headers are now C99-safe so a plain C host can include them.
proto-opencl/host.c: C99 + OpenCL 1.2 API, device list, runtime build, cache fill and FNV check, dataset build and
self-test, 3 vector warps standalone and in batch, bench and sweep as host.cu, whole-batch fingerprint. The 32-lane
exchange is sub_group_shuffle_xor only when the queried sub-group size for a 32-item work-group is exactly 32;
otherwise a local-memory exchange with one barrier per exchange, so wave64 hardware cannot change the hash
(WAVEFRONT.md). build.sh (macOS, Linux), build.bat (MSVC), README with the exact AMD-rig commands.
Proven without AMD silicon: Apple OpenCL 1.2 on the M5 Max 96/96 on all three packs (45.0 Mhash/s at 1 GiB, Apple
number, not AMD); pocl 7.2 CPU device 96/96 on both exchange paths including the real sub_group_shuffle_xor text;
CPU emulator 7 configurations incl. 64-wide sub-groups, identical fingerprint f99fb375b3abeaf5 everywhere.

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.
