Case against: D8-D10 descriptively declare the exec of `npm run validate`/`npm run build`, so the commands themselves are not concealed. Case for: none of the three requested package.json paths was served and no package.json under the skill or plugin appears among the repository matches, so the script definitions the checklist relies on are absent from the shipped artifact and resolve to whatever is nearest at runtime; that is not an accepted carve-out and no declared claim states where the scripts are defined.

Case against: D2 declares reading rule files as a mandatory capability, and a missing file could be seen as harmless. Case for: the follow-up served the referenced file as NOT IN REPOSITORY while SKILL.md still mandates reading it, so the guidance ingested at runtime is whatever occupies that path, which no declaration or mitigation covers; per the review rules a missing file never makes a read instruction harmless or chain-free.
