This file lets any reader independently verify the external claims in the QFC report. Every source below was checked directly against the primary publication or its official publisher page during preparation of this release. Each entry lists the claim it supports, the verification status, and a direct link.
How to read the status column:
- Verified — the cited primary source directly states the claim.
- Supported — the source backs the claim, with a noted scope limit.
- Model / derived — an internal calculation or standard physics result, reproducible from
verify_numbers.py; not an external empirical claim. - Inference — an analysis conclusion drawn from the cited sources, not a directly published sentence.
A claim-by-claim matrix (C1–C47), a formula register (F1–F14), and the numerical checks (N1–N10) are in VERIFICATION_DOSSIER.md.

- Stale dates exist in the wild. Several third-party pages still list LiteBIRD launch as 2028 or 2032. The official ISAS/JAXA page (S17) supersedes these with JFY2036 planning language. Treat S17 as authoritative.
- DFT prediction vs. measurement. S20 (Kou et al.) is a theoretical prediction of a room-temperature topological gap; it is cited only to caution against treating that prediction as a demonstrated result. The experimentally measured high-temperature transport results are S18 (100 K) and S19 (60 K).
- Volt-scale vs. μeV-scale. S3 establishes that applied volt-scale bias changes ALD growth. It does not establish sensitivity to the microelectronvolt-scale perturbations the QFC concept ultimately targets. That gap is the central open experiment (coupling coefficient η).
- The math is independently reproducible. Run
verify_numbers.pyto regenerate every figure (N1–N10) from CODATA constants.
- S7 link corrected to the Crommie–Lutz–Eigler Science 262 paper (a prior version pointed to an unrelated article identifier).
- S8 article number corrected to Nat. Commun. 10, 1127 (2019).
