2026-04-08Sync experiment+protocol scripts with v2.32 corrected control valuesYurenHao0426
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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
2026-04-08Add BP+penalty control (round 19's #4 critical experiment)YurenHao0426
Trains end-to-end BP with the same lambda*||f_l(h_l)||^2 penalty used in the DFA penalty rescue. Tests whether the penalty's depth utilization loss in penalized DFA is intrinsic to DFA's random-feedback credit quality (mode 2) or due to penalty-induced capacity regularization. Decision rule: BP+pen margin > 25 pp -> mode 2 confirmed (penalty is not the cap) BP+pen margin < 5 pp -> penalty itself caps depth (capacity loss) intermediate -> both effects present
