v2.4.18-mini — Pure-size compression of v2.4.18 (~×4 fewer params). Capacity scaled (d_model 128 → 64, Q-hidden 256 → 128, critic-hidden 256 → 128, world-model 512 → 256, replay 3.6M → 1.5M). Architecture preserved (mixer × 2 layers, 4 heads, 32 quantiles, critic depth 2, TD-MPC opt dim 48). CSC cell of the 2×2 capacity / CSC experimental matrix.
v2.4.18 — Symmetric CrossSampleCenter, per-sym distributional Q, world-model + CEM planner, Phase 19-20 branch-isolation regulator calibration.
v2.4 — N-agnostic refactor: branch / V_global separation.
v2.3 — 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.
