# UTFANSWF v23 — Frog 8/8 Reproducibility Overlay

Date: 2026-08-19

This directory is a **post-release/private research reproducibility overlay** added to the exact v23 update bundle recovered from the live UTFANSWF website. It does not rewrite the protected manuscript or historical gate outputs.

## Protected files

- `main.tex` SHA-256: `fd4fe7cf9a0d42e9a9a1def50d49c4a03d8fcd6772f857cc5a269e183986e34a`
- `main.pdf` SHA-256: `77b1fd720821e0398337a6a7fceed570dc50093534fe9b60795a1524e4a0cf54`

The Frog verifier fails closed if either hash changes.

## What this overlay adds

- the August 19 Frog 8/8 master closeout;
- the new one-QCD-generating-functional NP-QCD electromagnetic derivation;
- an explicit 8-item machine-readable status ledger;
- predecessor research checkpoints for provenance;
- a source hash manifest;
- `verify_frog_closeout.py`, executed automatically by the canonical one-command harness as an auxiliary integrity check.

## Canonical gate semantics

The canonical gate count remains **18**. No Row 30 is invented. Rows 27 and 29 remain historical executable records under their original scopes. The Frog overlay supersedes only the **current research interpretation**, not their stored historical outputs.

## Current Frog interpretation

Items 01 and 05 are GREEN at the derivation level because both missing electromagnetic hadronic responses are defined as target-free projections of the same renormalized QCD generating functional with a unit-normalized background electromagnetic source. Numerical nonperturbative execution and independent verification remain pending and are explicitly not claimed.

The full board status is recorded in `FROG_STATUS_2026-08-19.json`.
