PACC-Lab v0.5 — does a richer relation state rescue the latent coordinate?

A rich relation graph keeps far more source/pair/pattern information than the compact v0.4 bundle while leaving task actions identical. It does not rescue the frozen direct affine-sigmoid map to the common-cause coordinate: compact 0 and rich 0 robust passes, real/control ratios ≈ 0.96–1.02, and no system rescued in four secondary seeds. Counterfactual source-flip probes often pass alone, showing partial local directional alignment without a globally discriminative coordinate.

Research status: STABLE the current conclusions are relatively stable
Evidence level: E3 Repeated experiment
Result: NEGATIVE
Data basis: SYNTHETIC Synthetic data and theoretical reasoning. Many now treat synthetic data as if it were real; this laboratory says the opposite deliberately — until a real hybrid model exists, an inference is only an inference, and theoretically possible is not actually possible.

Hypothesis

hypothesis: The v0.4 failure was information loss in the compact state; a richer non-probabilistic relation state admits the direct low-complexity latent coordinate.

MOD-2026-0005 Bayesian reference (exact posterior / Beta-Bernoulli / joint common-cause / HMM)

Interpretation

interpretation: Richer raw relation state is insufficient for the tested direct low-complexity latent coordinate — not that the coordinate is information-theoretically unrecoverable. Points to a coordinate-composition problem (v0.6).

Limitations

limitations: A direct affine-sigmoid observer may be too restrictive even when the raw state is informative.

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.
