v2.4.18 — Symmetric CrossSampleCenter (E1 anti-bias) on actor head AND critic features. Per-symbol 16-quantile distributional Q. World-model + CEM planner contour (every 80 cycles). Pattern memory sign-balanced sampling. Phase 19-20 branch-isolation regulator calibration — portfolio-level constraints disabled at branch level; only deadzone-gated anti-pattern regulators remain.
v2.4 — N-agnostic refactor: branch / V_global separation; V_global Transformer observer; lean actor pipeline.
v2.3 — Two surgical fixes on v2.1: separate encoders, qg_new.detach().
v2.2 — Minimalist refactor under Simple_encoder.
v2.1 — Adapter rank-collapse fix; bias accumulation control; ResidualSkipHead actor.
v2 — Initial release.
