{ "worked": false, "confidence": 9, "verdict": "Implemented Identity-Paired Progressive Depth as an additive diagonal coupling block followed by its analytically computed inverse, inserted into the matched built-in sequence transformer. Across 8 paired seeds, the idea had higher test MSE than the tuned baseline (0.5841716528 vs 0.5621015988), with paired delta +0.0220700540 and permutation p=0.5933, so there is no task-metric win.
