  Honesty lock: tests fail a fake FeMoco energy

First-screen number: 108 Jordan–Wigner data qubits (2×54); published Reiher serial 111 logical / (1.0\times10^{14}) T; Lee–Berry–Gidney THC 2142 logical; Alexeev Class 2 (\gg)1000.

Problem

Biological nitrogen fixation (FeMoco) is the textbook reason chemists want a quantum computer. The 2017 Reiher–Troyer resource estimate put a CAS(54e,54o) fragment on the order of 10^14 T gates. Nobody should ship a hackathon page that pretends that calculation ran on a laptop.

What it does

• Maps a second-quantized Hamiltonian with Jordan–Wigner (Bravyi–Kitaev number-operator bake-off).
• Grows an ADAPT-VQE ansatz on H2 STO-3G and a documented 8-qubit model [2Fe–2S] Hubbard fragment.
• Applies Richardson zero-noise extrapolation.
• Prints a resource estimate whose wall is already on the CLI: Jordan–Wigner 108 data qubits (2×54), published Reiher serial 111 logical qubits and 1.0×10^14 T, Lee–Berry–Gidney THC 2142 logical qubits, Alexeev Class 2 ≫1000 for full FeMoco. Embedded Fe2S2 (30–50 LQ) is the 25–100 window. Not a compiled FeMoco energy.
• Cost-aware ADAPT (the one increment): next operator is max |gradient| / (1 + CNOT-proxy).

What it does not do

It does not compute FeMoco FCI. It does not solve Haber–Bosch. LiH and BeH2 are classical FCI + resource-wall rungs in the default CLI.

How we built it

Python + NumPy + SciPy + PySCF. Fermion-to-qubit maps, ADAPT-VQE, Richardson ZNE, and a cited resource estimator. Honesty tests fail if the pack claims a solved nitrogenase problem or an FeMoco full-CI energy.

Setup

git clone https://github.com/moscraciunxxx/fermi-fix
cd fermi-fix
pip install -r requirements.txt
PYTHONPATH=src python -m unittest discover -s tests -v
PYTHONPATH=src python -m fermifix.cli estimate --orbs 54 --electrons 54 --cite reiher2017
PYTHONPATH=src python -m fermifix.cli ladder --out artifacts/ladder.json

The estimate command prints 108. No Seagate path. No localhost.
