fusion-invariants-lint-validates-structure-not-function
The fusion-invariants-lint.py script validates structural shape (section-header regex + taxonomy blacklist) but cannot verify that skills actually work end-to-end. A 71/71 PASS means the corpus is correctly shaped, not that ‘natural-language intent → production URL in 22 min’ executes correctly. Functional verification requires live end-to-end smoke tests, which do not yet exist.
