This iteration uses an updated technique to apply that projection more effectively.

Each round learns from thousands of paired rewrites of the same scene, one side with the tic and one side without, so the only preference expressed is the construction itself.</li> <li><b>Merge faithfully.</b> The trained deltas are folded into bf16 weights with stochastic rounding at fidelity 1.000.</li> </ol> <p class="note">This is a research artifact, not a product.
