 the next method change must supply task memory rather than tune shared-feedback
 strength.  If P0 passes, the chosen configuration enters the same 40-epoch,
 three-seed BP/clean-KP/raw/SDIL comparison as B1.

+## P0 outcome
+
+All eight runs were finite, but no feedforward candidate passed.  The best BP
+rollout success was `63.6%` (four layers, learning rate `0.03`) and the best
+clean-KP success was `52.2%` at the same setting, below the frozen `70%` and
+`60%` thresholds.  Their expert-action accuracies were `84.81%` and `83.84%`.
+Removing the mission reduced the best BP policy to `11.6%` success, confirming
+that this task depends on the language signal.  Raw and SDIL were not run.
+
+The next clean-only feasibility stage keeps the best P0 depth and learning rate
+and adds a fixed basal history of observations and previous actions.  It tests
+history lengths four and eight for 25 epochs, using only BP and clean KP.  The
+same `70%` BP, `60%` clean-KP, and 20-point BP mission-lesion thresholds apply;
+ties favor the shorter history.  This changes the missing state information,
+not the shared-feedback signal or its strength.
