Mouillay GPU Miner 1.0.3-rc3 - experimental SM120 test

Windows RTX 50-series / compute capability 12.0 required.
Run TEST_SM120.bat with other miners stopped on this GPU.
Two 30-second measurement phases plus warm-up and candidate capture.
Send the two result files from the logs directory.
This is a native kernel/adapter diagnostic, not pool mining.
No TH/s value is claimed until exact work and consensus proofs are qualified.
Use RC2 or stable builds for ordinary mining.
Original component provenance is retained in COMPONENT-NOTICE.txt.
