A seed-locked, byte-deterministic general-ledger dataset built to showcase causal counterfactuals: for each named intervention, a baseline ledger and a counterfactual ledger are generated under identical randomness. Both runs are byte-identical on reruns, so every difference is the intervention's effect, not RNG noise. The diffs config isolates exactly the journal-entry lines that changed. This is the tangible artifact of the… See the full description on the dataset page: https://huggingface.co/datasets/VynFi/vynfi-counterfactual-gl.
