The `prefer-use-over-utilize` reference rule's prompt asks it to "cover the inflected forms", but its swap held only `utilize`, `utilizes` and `utilizing`. A rule generated correctly from the prompt, with fail cases like `We utilized the API`, was graded against a reference that did not fire on them, so taskless/taskless's generation evals counted correct fixtures as wrong.

• The swap adds `utilized: used` and `utilization: use`, each with a reference fail case (`tests/fail/utilized-past/`, `tests/fail/utilization-noun/`), listed in the corpus manifest.
• The prompt now names the forms it is graded on, including the noun, so a generation that follows it passes the held-out cases.
• `assets/reference.json` is regenerated. Its `version` is unchanged: the shape is the same, only one entry's content moved.
• `test/reference-verify.test.ts` stages the published vale entry as a consumer would and verifies it against its own cases. With the old swap restored it fails with the two `fail case did not fire` errors from the issue.

Only the vale reference was failing evals, so the sg and runtime entries are out of scope.
