PACC-Lab v0.13 — reverse residual field / base-point dependence
The held-out reverse residual r_CA(S) = Φ_A(S) − T_CA(Φ_C(S)) is measured for mean, covariance, latent-logit energy concentration, between- versus within-stratum variance, direction stability and a train-only per-stratum constant correction against global and shuffled-stratum controls. N0/N1 concentrate 98 % of residual energy on the latent-logit axis, yet the mean direction flips sign across seeds (cross-seed cosine ≈ −1), between-q structure is ≈ 0.1–0.3 % against a 20 % gate, and stratum correction changes held-out fidelity by < 10⁻⁵ — no family passes.
Hypothesis
hypothesis- The reverse bias is a base-point-conditioned residual field r(S) ≈ b_q + ε learnable per frozen overlap stratum.
Setup

Interpretation
interpretation- A stable residual axis is not a stable residual orientation and not a base-point field; the reverse bias contains family-dependent dominant error modes, which weakens the gauge/connection-like reading. Next (v0.14, preregistered): sign-free residual subspace / principal-axis stability, with no q input, no higher degree, no neural mapper.
Limitations
limitations- Residual unstructuredness is not established in every sign-free or subspace sense — that is the v0.14 question.
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.
