PACC-Lab v0.1 — E0–E4: first micro-witness
Three primitive-level non-probabilistic systems (N0 signed support, N1 ordinal tournament, N2 signed graph) integrate evidence over four hidden hypotheses next to an exact Bayesian reference. All three pass the Level-3 micro criteria — held-out JS ≤ 0.0101, update JS ≤ 0.0042, intervention JS ≤ 0.0058, action agreement ≥ 0.957 — in both uniform and heterogeneous evidence quality, with shuffled-target controls around 0.31–0.33. The redundancy diagnostic collapses N0 and N1 into one exact reparameterization family, leaving two independent families against a PACC-A minimum of three.
Hypothesis
hypothesis- A system whose canonical state and update rules do not require probability can converge toward a Bayesian reference in behaviour, held-out state representation and update dynamics.
Setup
model_idsdataset_idssoftware_environment- Python; deterministic seeded generators; no network, no LLM.

Interpretation
interpretation- Non-probabilistic primitives can exhibit probability-like state and update structure in controlled micro-tasks; two independent convergent families are not enough to establish a computational attractor. Under uniform reliability additive signed support is closely related to rescaled log-evidence accumulation — the heterogeneous stress makes the result less trivial, not deeply equivalent.
Limitations
limitations- Does not show probability is false, Bayesian inference unnecessary, LLM internals equivalent, non-probabilistic systems superior, or probability an observer projection.
- E4 dynamic-world numbers are descriptive only (HMM hazard and decay untuned).
Reproduction
reproduction_instructions- Extract the version's FINAL bundle; python -m pytest -q; run the version's primary script with the recorded seed; docs/PACC_LAB_v0.N_RESULTS.md and docs/EXPERIMENT_PROTOCOL_v0.N.md are inside the bundle.
