layer.yaml drops standard_version (A12) and is marked derived: true,
derived_from: INTENT.md (A11); INTENT.md frontmatter already carries the
governing layer: Engine and no standard_version. The checker changes in
the same commit: standard_version is no longer required and its presence
is now malformed, the derived marking is required, the layer is compared
against the closed four-token vocabulary after an ASCII fold (A9), and a
divergence between INTENT.md and layer.yaml that survives the fold is
reported. Nothing is re-spelled: Engine and engine both stand. The tests
assert the fold rather than equality. pep-stance.yaml is untouched.
