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

The pre-v2.31 unsourced values BP=0.609 and DFA=0.308 (which v2.31 fixed
to 0.585 and 0.301 via matched 30-ep controls) were also hardcoded as
"compare to" comments in 5 helper scripts:
experiments/bp_with_penalty_control.py
experiments/dfa_residual_penalty_test.py
experiments/resmlp_frozen_blocks_baseline.py
protocol/examples/threshold_d_sensitivity.py
protocol/examples/plot_penalty_rescue.py
These are non-paper-input scripts (their output goes to stdout, not to
the paper), so the stale values didn't cause numerical errors in the
paper itself. But the original v2.31 BP+pen=0.609 unsourced number bug
came from exactly this kind of hardcoded "for-comparison" comment that
was never measured. Updating them now to remove the same trap from
future runs.
Each script now references the matched 30-ep 3-seed values from
results/bp_no_penalty_30ep, results/dfa_no_penalty_30ep, results/
dfa_pen_short, and results/bp_with_penalty.
protocol/EVIDENCE_SUMMARY.md and PAPER_OUTLINE.md still have stale
numbers — these are project scratch documents and not user-facing.
Deferred to a separate sweep if needed.
