The DRAT bytes are not in the git tree. The JSON in this folder is the cube index. See ../../STORAGE.md.

DRAT proofs for exact Caccetta–Häggkvist triangle leftover orders from n=121 onward. q11 stays the n=120 store.

n=121 is stored (38 cubes, k=41..78). First remaining hole n=122.

A d-outregular oriented graph has n d arcs, so some in-degree is at least d. Relabel that vertex as 0. The exact statement reduces to cubes k=|N⁻(0)| ≥ d. Each stored cube is UNSAT with a DRAT. Replay regenerates the CNF from encode.py and checks the proof; do not trust leftover certs/*.cnf scratch files.

The index is replay.json after a successful verify_keep.py. Independent range log: replay_121.json.

F₄ stays in ../q4/ at c=0.34640.
