     (as in parcae). If (a) holds while rec arms failed it, the
     fixed-point-location dial is causally isolated: same learnable-decay

+--- Outcome, item 12 (scored 2026-07-15): prediction (a) CONFIRMED in its
+dynamics half, REFUTED in its fidelity half — and the refutation is the
+finding. Dynamics: rho stayed in (0,1) throughout (0.300 -> 0.292, the
+optimizer drifting MORE contractive when confined to the stable region);
+loss trajectory as good as or better than the unconstrained arm at every
+checkpoint (the rec arm's flight to rho~4.5 was epiphenomenal — all fit
+lives in the MLP); eval saturates completely (hard 42.9/42.9/39.3/39.3/
+39.3 at k=2/4/8/16/32, easy flat ~71%). Fidelity: easy items were NOT
+preserved (71% vs the merge's 88.5%) despite guaranteed contraction —
+substrate fidelity is controlled by fixed-point LOCATION (anchored B +
+curriculum), not by rho. Conclusion: stability and fidelity are
+independent dials (fig_phase.png); the Parcae constraint delivers exactly
+what it promises (robust training, convergence, certified tail gradients)
+and exactly nothing more. Item 14 (tied-alpha) is the causal isolation of
+the fidelity dial.
