+**Oral-B-v2 development path: two failures retained.** `ORAL_B_V2.md` adds an
+explicit terminal reward/timeout phase, a local TD critic, and eligibility
+traces without changing the old R2. Its complete 24-record development grid
+fails from a cold start: the dense performance innovation was scaled to
+one-quarter of the validated rule and no candidate learns. A separately frozen
+unit-scale recovery restores 100% task performance and passes every mechanism
+gate on task seeds 23 and 24; task seed 25 passes 17/18 gates but succeeds on
+98.96% of a fixed absolute target ladder. That class-balance failure is also
+retained and does not open confirmation.
+
+**Oral-B-v2 calibrated R1/R2 status: passed.** The final branch changes no
+learning parameter. Five target levels are fixed by cursor-maximum quantiles
+on 512 separate outcome-free calibration trials, then evaluated on independent
+trajectories. Fresh development seeds 26--28 pass all 18/18 checks. The
+untouched 6-task by 5-model confirmation then passes every learning,
+innovation, network-prediction, outcome, lesion, and task-cluster confidence
+gate: final success is `100%`, learning gain `98.80` points, fixed-role gap
+`99.97` points, role cosine `0.9761`, residual--soma correlation `0.0631`,
+surrounding accuracy `54.37%` (lower bound `54.26%`), velocity advantage
+`0.6384`, terminal outcome accuracy `99.83%` (lower bound `99.68%`), acute
+outcome-lesion separation drop `0.4000` (lower bound `0.3886`), critic
+expectedness `0.3187` (lower bound `0.2814`), and 30/30 positive signs. The
+formal milestone rises from 7 to 8. The old oral-A gate remains closed; only a
+new independently frozen oral-A-v2 protocol may now run.
