RESEARCH GUIDE
DOCUMENTED HARDWARE
Research chapters explain the hardware. Production records separately show what REFORGE has tested or corrected.

VERIFICATION
PARITY BOUNDARIES
A passed boundary applies only to the named claim and evidence row below.
A native artifact is produced.
The requested headless run completes.
Fresh visible output is verified.
Scripted input changes title state.
Named game rules pass deterministic checks.
Corpus, build receipt, and human acceptance gates pass.
