Model checkpoints from the oracle-encodings modular-addition experiments (frozen "oracle" Fourier features injected into the residual stream of a 1-layer transformer grokking (i + j) mod p).

Layout: run_<timestamp>/<experiment>/checkpoints/<label>/ep<NNNNNN>.pth — one run_<ts>/ tree per runner invocation; the label encodes the sweep axes (e.g. n2_s0 = 2 injected frequency pairs, seed 0; delay4000_n2_s1, amp2_n3_s0, rel0.5_n2_s2, ...). Each .pth holds {model: state_dict, config: Config fields, label, epochs_done} — the frozen oracle is NOT in the state_dict; rebuild it from the run spec embedded in the sibling <experiment>/<label>.result.json (modular_addition.oracle.sweep.build_oracle).
