A12 r2 reaches every key and value of the declaration, including the
companion's version. The standard: path in INTENT.md was already
unversioned and is unchanged. tests/test_layer_declaration.py fails if a
version key, a versioned standard path, or companion_version returns to
the INTENT.md frontmatter or layer.yaml; schema_version and comments are
not reached. One prose citation ("the v0.5 scope rule") in a rationale
value is allowlisted by exact text and reported to gate-house as open.
