 `68.4x` ordinary training work, with `108.2` seconds mean wall time. The next recovery must retain
 the vectorizer and disclose how much of this query burden it avoids.
 
+### Calibration-quality development screen (task seed 0 only)
+
+The first post-diagnosis development screen kept the context vectorizer and concurrent A/W updates
+fixed, replacing simultaneous K1/e4 calibration by layerwise K4/e4 or K16/e4. The frozen rule
+selected the higher mean d4 endpoint, preferring K4 within one point; all three model seeds and
+both depths are retained.

+| directions | depth | validation acc (%) | depth gain | d4 lesion drop | d4 work / ordinary |
+|-----------:|------:|-------------------:|-----------:|----------------:|-------------------:|
+| K4 | 1 | 66.217 ± 5.264 | — | — | — |
+| K4 | 4 | 65.633 ± 27.078 | -0.583 | +13.733 | 5.5x |
+| K16 | 1 | 65.917 ± 4.753 | — | — | — |
+| K16 | 4 | 65.567 ± 26.962 | -0.350 | +14.033 | 18.2x |
+
+Only one of three depth pairs and one of three d4 lesions are positive for either candidate. K16
+has one nonfinite d4 final loss and is ineligible; K4 is selected mechanically but is not advanced
+to independent confirmation because its mean depth gain is negative. **Better per-event causal
+targets do not by themselves cure the coupled A/W basin.** The next bounded development question
+is temporal: calibrate A while W is held fixed, then open forward plasticity and maintain A with
+the already selected low-query simultaneous schedule.
