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=122 onward. q12 stays the n=121 store.
n=122 is stored (39 cubes, k=41..79). First remaining hole n=123.
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.
