The rules come from the first Eureka pipeline-state cuts. Soul could not rerun
mutations that were only named. A digest captured from new code proved nothing
about the old code. A detached mutation script died silently on a parse error.

Eureka is extracted from the Aetheria CultCache migration and is the Claude
Code counterpart of Epiphany. It covers the faculty loop, brief templates,
the cut map shape, the postmortem template, the worked example, a dated
comparison with Epiphany, and a changelog tying each rule to its evidence.
