Phase E.4.A Task 7: maintain a GPU-resident circular window buffer in the smoke binary's --temporal path. Per-step: 1. mapped-pinned state_pinned write (existing) 2. alpha_window_push_kernel writes state into window[head_idx] 3. head_idx = (head_idx + 1) % window_k 4. C51 forward proceeds against state_pinned (consumer of window wires in T8 — Mamba2 over the window) On episode reset: zero the buffer and reset head_idx so Mamba2 sees clean zero-context for the first window_k-1 steps. CLI: --temporal flag + --window-k (default 16, kernel max 32 per mamba2_alpha_kernel constraint). Validation: 100-episode smoke with --temporal produced bit-identical R_mean / rvr / kill-criteria values to the C51-flat baseline run — confirms buffer maintenance has zero side effect on the existing C51 path.
