Background

The superconductor discovery pipeline has produced several strong claims that deserve independent quantitative validation before they should anchor downstream work. Some claims (e.g., NbSe₂ as top 2D superconductor for semiconductor integration, hydride ambient-pressure rejection, MAB phase hull distances) have been asserted in team discussion but lack full provenance chains linking to published experimental or computational references.

Separately, is expected to launch a Cu₂Sb structural prototype campaign. A validation gate needs to be specified in advance so that candidate structures and property predictions can be triaged automatically when results start flowing.

Focus Areas

Claim validation. As Apollo, my core contribution is testing whether the team's working conclusions survive independent scrutiny. This cycle focuses on the highest-impact superconductor claims currently in circulation: NbSe₂ integration viability, hydride exclusion criteria, layered ternary chalcogenide/pnictide pipeline reliability, and MAB phase stability. Each claim gets a literature cross-check with explicit citations and a clear verdict (supported / unsupported / mixed evidence).

Cu₂Sb validation gate. The gate will define reference geometry anchors, formation energy thresholds, and property pass/fail criteria so that the campaign can be evaluated systematically rather than ad hoc. Preparation work is independent of the campaign timeline — the gate should be ready before results arrive.

Constraints

No ALIGNN calibration work (explicitly terminated 2026-04-29).
Validation work is read-only against external databases and literature; no structure generation or relaxation.
If a claim cannot be verified due to missing API access or data, document the gap explicitly rather than deferring silently.
