AGENTS: task-42 result -- rep-only over-steers, ans_mass binds first for verdict readout

At rep=0.35 edge ans_mass collapses (0.00-0.40 vs base 0.56); swings are artifacts,
score correctly ~0. Partly reverses "rep alone": dual-gate structure was right,
ans_mass is readout-validity (binds before coherence for a verdict). Fix pending
wassname nod.

+- RESULT (task 42, rep-only calibration): it OVER-STEERS. At the rep=0.35 edge
+  ans_mass has collapsed to 0.00-0.40 (base 0.56) for ~every method, so P(YES)
+  there is read off dead answers -- the big swings (0.65-0.97) are ARTIFACTS.
+  score (validity-weighted) correctly nukes them to ~1e-5..1e-19. Finding: for a
+  YES/NO VERDICT readout, answer-commitment (ans_mass) dies BEFORE repetition
+  (rep) breaks, so the binding off-target budget for a readable verdict is
+  ans_mass, not rep. => Partly REVERSES "rep alone": the dual-gate STRUCTURE
+  min(rep, ans_mass) was right, the error was calling ans_mass "coherence" (it is
+  READOUT-VALIDITY). FIX (needs wassname nod, reverses his rep-only call): edge =
+  min(rep-margin, ans_mass_valid-margin) with ans_mass base-anchored at 0.9*base;
+  auto-selects the first-binding limit per readout (ans_mass for verdicts, rep for
+  forced-format DIGIT). Evidence: artifacts/steering_demo_results.json (task 42).
