 The broad endogenous-traffic gate and the Harnett desired-velocity/online-control
 screen failed. Those results are retained and explicitly constrain the paper:
-SDIL does not currently explain the reported error-derivative signature, and
-the residual mechanism is supported for traffic predictable from the chosen
-somatic statistic rather than arbitrary top-down context. `ROADMAP.md` and
-`ORAL_B.md` contain the frozen gates and complete negative branches.
-A mechanics-only recovery now separates perturbation-learned causal role from
-within-episode performance velocity; it passes its algebraic checks but has no
-task endpoint and does not yet weaken this limitation.
+SDIL does not currently explain the complete reported dendritic population
+signature or online control, and the residual mechanism is supported for

+A temporal-difference recovery separates perturbation-learned causal role from
+within-episode performance velocity. Its development gate selects `eta=0.1`
+with 98.05% worst-task success, and its untouched 30-record confirmation
+retains 99.53% mean success, positive sign inversion in all 30 records, and a
+0.639 velocity-over-error correlation advantage. The complete R2 gate
+nevertheless fails: residual outcome decoding is only 47.33%, residuals trail
+soma by 4.32 points, and the longitudinal correlation is `-0.013`. Thus the
+recovery sharpens the boundary--causal-role temporal-difference plasticity
+works in this synthetic task, but the broader Harnett-like population
+vectorization signature is not established. The strict score remains 7/10
+and the oral-A depth panel stays sealed.
