Round 20's minimal lock-in experiment: 3 seeds × {ep 1, ep 2} vanilla
DFA cosine. Closes the 'single-seed fluke' objection.
Vanilla DFA early-epoch deep cosines (l1-l4):
| seed | ep | ||g|| | deep mean |
|---|---|---|---|
| 42 | 1 | 6.7e-7 | -0.025 |
| 42 | 2 | 1.5e-7 | -0.038 |
| 123 | 1 | 6.5e-7 | +0.002 |
| 123 | 2 | 1.4e-7 | -0.006 |
| 456 | 1 | 3.9e-7 | +0.000 |
| 456 | 2 | 8.5e-8 | -0.009 |
3-seed mean at ep 1 (most meaningful regime): -0.008 ± 0.013
3-seed mean at ep 2: -0.018 ± 0.018
ALL 24 measurements (3 seeds × 2 ep × 4 deep layers) are in [-0.04, +0.02].
Compare to penalized DFA 3-seed mean +0.155 ± 0.025.
The penalty CREATING deep alignment finding is now seed-robust. Three
seeds × two early epochs all show vanilla deep cos essentially zero
even when ||g|| is in the meaningful regime.
This is the round 20 lock-in. Framing is locked.
