The specification version a `codecheck.yml` is validated against

codecheck_spec_version.RdRead from the `version` node, including the historical `https://codecheck.org.uk/spec/1.0` form that certificates from 2020 carry.
Details
A file without a version node is dated instead: the version that was current when the CODECHECK was performed (`check_time`, or `modified`) is used, so a configuration written in 2020 is not judged against requirements published in 2026. Only a file that cannot be dated falls back to the newest version, which is what the specification asks tools to assume. See "Choosing the specification version" in the register's `RULES.md`.
