3D Sign Nets (SRAG): Superconductor Layer-Compatibility Bypass With Alignment Before Mechanism

Significant — This superconductor materials article, 3D Sign Nets (SRAG): Superconductor Layer-Compatibility Bypass With Alignment Before Mechanism, is the first of three related writeups that push layered superconducting and adjacent materials comparisons into a contract-grade, reproducible format instead of a best-plot narrative. The core contribution is a pad-first 3D alignment method: each sample or condition is projected into a declared pad, fixed offsets are applied under a declared offset policy, and the comparison is performed only on the resulting intersection support so that agreement cannot be manufactured by quietly changing what counts as overlap. Missingness is handled as an explicit part of the record (zeros are written rather than implied), and tightening is replay-only so the result cannot be improved by post-view trimming, re-centering, or extractor substitution. The net effect is a stable, auditable object for superconductor and materials claims tied to layer count, pressure, and scan conditions: the same pad, the same offsets, the same intersection rule, and the same missingness accounting can be replayed to verify that a reported trend is not an artifact of corridor travel. This raises the bar by making cross-sample and cross-condition comparisons admissible only after the alignment contract is fixed up front, while still allowing multi-layer representation when it is needed to separate dead-versus-cloaked behavior, lag, or path dependence.
