+# Development-only feedback-first timescale screen. Task seed 0 is reused;
+# untouched task seeds 6--8 remain reserved for independent confirmation.
+#
+# The joint phase is the original context-SDIL K1/e4 simultaneous protocol.
+# Before it, A receives 0/100/400 layerwise K4 calibration steps while every W
+# and bias (including the readout) is frozen. See the analyzer for the frozen
+# eligibility and smaller-prefix-within-one-point selection rule.
+# Usage: c2_feedback_warmup_pilot.sh <gpu> "<model seeds>"
