| Sparse exchange terms are encoded as `[i, j, J]`, where `J` is a scalar, |
| a length-three diagonal, or a 3-by-3 matrix. Missing fields are zero. |
| HamiltonZero expands this representation when loading a system. |
| |
| `train/foundation_5000.jsonl` contains the 5,000 systems used by the released |
| foundation checkpoint, with sizes from 2 to 64 spins. Each row includes the |
| fixed WL1/FWL2 dispatch and, where available, `e_ed` in textbook energy units. |
| There are 3,169 non-null exact-diagonalization references. |
| |
| The N≥256 evaluation systems are: |

| | File | Physical spins | Family | |
| |---|---:|---| |
| | `eval/ppp_ohno_n256.json` | 256 | PPP–Ohno C128H130 | |

| | `eval/ppp_ohno_n1024.json` | 1,024 | PPP–Ohno C512H514 | |
| | `eval/rudy_n256.json` | 256 | RUDY-12 MaxCut | |
| | `eval/rudy_n512.json` | 512 | RUDY-12 MaxCut | |

| | `eval/j1j2_45x45_obc.json` | 2,025 | square-lattice J1–J2 | |
| | `eval/triangular_42x42_pbc.json` | 1,764 | triangular Heisenberg | |
| | `eval/j1j2_64x64_obc.json` | 4,096 | square-lattice J1–J2 | |
| | `eval/j1j2_90x90_obc.json` | 8,100 | square-lattice J1–J2 | |
| |
| Each evaluation record stores its fixed WL1 routing dispatch. |
| |
| All stored couplings and reference energies use the textbook convention above. |
| Padding is reconstructed in memory and is not stored as zero-valued sites. |
