src/check.bend checks
raw source on the hub · import shake@0.4.0.0/src/check.bend as Check
shake/check: the ways a Cli can contradict itself, internal (main.bend
exports check). parse does not call it: a program checks its spec once,
and every guarantee of SPEC.md's parse rows holds for a spec check passes.
