    <article class="card wide"><h2>Matching lower-bound mechanism</h2><p>The cited two-type/two-action construction was rebuilt directly. Both wrong-region gaps equal <code>2 epsilon</code>. Across 16 exact Bayes tests, <code>N epsilon^2 / ln(1/delta)</code> stays between <strong>0.00834</strong> and <strong>0.02153</strong>, exercising the claimed rate.</p></article>
    <article class="card"><h2>Negative control</h2><p>Shared latent types violate i.i.d. sampling and fail, showing the positive certificate is not an always-success check.</p></article>
    <article class="card wide caveat"><h2>Scope boundary</h2><p>Finite executable certificates support the theorem mechanisms, constants, and scaling; they cannot prove a universal distribution-free theorem. The paper states constant 6912 but later uses 13824 in its proof, and the cited lower-bound probabilities require epsilon below 1/8.</p></article>
