| # CI rehearsal for the upcoming flawd mutation gate (dogfooding). | |
| # This branch is a measurement probe and will NOT be merged: it times the | |
| # pieces the real workflow needs on a hosted runner — flawd install from the | |
| # public mirror, the unentitled failure mode, coverage generation, and the | |
| # Docker image build — so the real mutation.yml lands with honest numbers. | |
