Task 04's session read the given test and the check.rs skeleton, both holding the tags the check refuses, and Ornith took them for its own template. It lost track of the file and made no change. The tags are now built with concat! and format! in check.rs and in the four given tests that held them, and the spec describes them in words. The rewritten tests pass against the reference, are rustfmt-clean, and still catch the case-folding mutation. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
