Subject: Find setting where both FA and DFA fail: d=512 L=2 ResMLP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TASK COMPLETE: Found 3/10 seeds where BOTH FA and DFA fall below
the frozen-blocks baseline while reporting positive cosine and
nontrivial accuracy — proving that the standard evaluation pair
can simultaneously miss both FA and DFA on the same setting.

Setting: d=512 L=2 pre-LayerNorm ResMLP, CIFAR-10, 100 epochs
Frozen baseline (3-seed mean): 0.349

Qualifying seeds:
  seed 1: DFA=0.298 (cos +0.206), FA=0.347 (cos +0.484)
  seed 2: DFA=0.297 (cos +0.179), FA=0.346 (cos +0.472)
  seed 5: DFA=0.296 (cos +0.194), FA=0.341 (cos +0.492)

All qualifying cases have:
  - Both methods below frozen baseline ✓
  - Both methods report positive aggregate cosine ✓
  - Both methods above chance (~0.10) ✓
  - Standard reporting pair (acc + Γ) would NOT walk back either ✓

DFA is below frozen in ALL 10/10 seeds (mean 0.300 ± 0.009).
FA is below frozen in 3/10 seeds (mean across all 10: 0.370 ± 0.026).

Also includes:
- Frozen baselines for d=512 at L=2,4,8,12 × 3 seeds (12 runs)
- resmlp_frozen_blocks_baseline.py patched with --num_blocks arg
