# UTFANSWF Row 27 — Blind Fine-Structure Checkpoint

This directory preserves the August 14, 2026 post-release UTFANSWF 1/137 research checkpoint used by executable Row 27.

The executable gate intentionally makes a narrow claim:

- `alpha^-1 = 137.03735243` is preserved as the closest legitimate blind intermediate checkpoint.
- The measured/withheld value `137.035999177` is used only for post-freeze comparison.
- The difference is `+0.001353253`, approximately `0.0009875164%`.
- The later verified mixed corrections give the separate rung `137.00222764`.
- The final source-complete electroweak handoff/Jacobian remains open.
- Independent verification was requested; this package does not claim that verification has been completed.

The archived independent-verification ZIP is included byte-for-byte and Row 27 checks its SHA-256 plus its internal `SHA256SUMS.txt` manifest.
