POST /api/log stores a log snapshot in Neon table miner_logs over the HTTP SQL
endpoint with no dependencies. upload-log.bat posts the last 256 KB of a log from
Windows with the curl.exe that ships with it. tools/logs.mjs lists runs and prints
the latest lines on the Mac.

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.

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.
