PCC = Probe-based Constraint Consistency(プローブに基づく制約整合性)。通常は目標に近い想像を選ぶ。PCCは壁・扉違反を加点し、候補を作り直さず順位だけを変える。PCC = Probe-based Constraint Consistency. Baseline selects imagined goal proximity. PCC adds wall/door risk and changes ranking, not generation.

「有意だが小さい」。改善はcross-wall で約+2.5ptに集中。ただし当該層の順位付けheadroomは約0.57で、その大半は依然回収できていない。"Significant but small." The gain concentrates in cross-wall (~+2.5 pt), but ~0.57 ranking headroom in that stratum remains largely unrecovered.

test正解でその場フィットした非展開の天井推定器(勾配ブースト木)C1でさえ、10セルのどこでも+0.05に届かない(door-shift: dino+0.020 / jepa−0.004)。学習型M2–M4も利得・害<閾値。C1 (GBT fit on test labels, non-deployable) reaches +0.05 in no cell; learned M2–M4 show gain/harm below gate.
主張が「線形PCCは効かない」→「凍結潜在の実行前特徴に、選び損ねを直す情報が無い」へ格上げ。線形だからではなく、情報そのものの限界。Upgrades the claim from "linear PCC fails" to "the frozen pre-execution features lack the information to fix mis-selection."

容量制限付き行動条件JEPAは、行動と相関するが力学・報酬に因果のない信号に潜在容量を割くか。報酬ラベルなしでそれを除去しつつ行動由来の物理力学を保てるか。Does a capacity-limited action-conditioned JEPA spend latent capacity on an action-correlated signal with no causal effect on dynamics/reward—and can paired intervention remove it without reward labels while preserving action-sensitive physics?
状態x_t・行動a_t∈[−1,1]・8次元nuisance d_t(力学/報酬から除外)。grid ρ∈{0,.5,.9}×β∈{0,.5,.9}×容量k∈{4,8,16}、4手法+state-only oracle、報酬なしペア介入loss、ID+相関反転OOD。RTX 2060安全(≤4.5GB)。State x_t, action a_t∈[−1,1], 8-D nuisance d_t (excluded from physics/reward). Grids ρ×β×capacity k, four methods + state-only oracle, reward-free paired-intervention loss, in-distribution + correlation-reversal OOD, RTX-2060-safe (≤4.5 GB).
H1 高ρ高βセルはnuisance占有が高く反転OODが悪い。H2 PairInv-JEPAはnuisance占有を下げる。H3 PairInv-Delta-JEPAはOODの物理状態保持を改善(ID性能低下は≤0.05)。H4 Delta-JEPAは行動感度を上げるが、nuisanceが行動相関だと占有は必ずしも下がらない。H1 high-ρ/β cell: more nuisance occupancy, worse reversal-OOD. H2 PairInv-JEPA lowers nuisance occupancy. H3 PairInv-Delta-JEPA improves OOD physical-state retention (ID drop ≤0.05). H4 Delta-JEPA raises action sensitivity but may not lower occupancy when nuisance is action-correlated.
