Phase E.4.A Tasks 11+12: backtest binary gains the same
--temporal Mamba2 forward chain as the smoke binary, plus the
--isv-continual flag that fires the stacker-threshold controller
at the end of each eval episode (Pillar B).
Changes:
- Imports: ml_alpha::mamba2_block::{Mamba2Block, Mamba2BlockConfig},
ml_core::cuda_autograd::gpu_tensor::GpuTensor
- CLI flags: --temporal, --window-k, --mamba2-hidden-dim,
--mamba2-state-dim, --isv-continual
- Cubin loading: alpha_window_push + stacker_threshold_controller
- Q-net sizing: c51_input_dim = mamba2_hidden_dim when --c51 --temporal
- Buffers: window_tensor GpuTensor, h_enriched_buf_dev, isv_dev,
ctl_wiener_dev
- Training inference path: push + Mamba2 forward + h_enriched →
C51 forward (mirrors smoke binary)
- Training batched compute: terminal Mamba2 forward, h_enriched_buf
for current/next, c51_input_dim threading
- Eval inference path: push + Mamba2 forward + h_enriched → C51
forward + Thompson select (with scoped borrow guard)
- T11 ISV-continual: stacker-threshold controller fires at end of
each eval episode; ISV slot 543 (threshold), 545 (observed-rate),
546 (Kelly atten) update with realized rollout stats. Co-exists
with the τ-grid sweep (τ-grid still gates; ISV updates parallel
observation of "live deployment" behaviour).
- JSON output: new fields temporal, window_k, mamba2_hidden_dim,
mamba2_state_dim, isv_continual.
