Run each benchmark arm in a hermetic fixture-only world materialized outside the repo, so the no-skill baseline can no longer discover the skill's assets on disk. The new-skill arm's skill is materialized to an isolated temp path it is pointed at; the baseline gets no skill and is told to stay within its world. A live 5-trial axi-review run confirms the fix: all baseline transcripts are clean of AXI-PRINCIPLES.md, the baselines invent their own generic rubric (the honest counterfactual), and the Efficacy verdict is green 5/5 where the contaminated 0004 run had scored red 2/5. Runner prose only; the deterministic core is untouched.
