foxhunt/scripts/argo-train.sh
jgrusewski 0ad5b6fa42 chore(sp13): script bug fix + Layer B implementation notes 
While P0b smoke (train-sw4ws on bdc5cb8bb) runs, two prep items:

(A) scripts/argo-train.sh — add `ci-training` to the L40S sm_89 case
    arm. Bare `ci-training` is an L40S pool alias in some clusters;
    previously defaulted to sm_90 (Hopper), causing train-mnpf7 to
    deploy with wrong-arch cubins (terminated + resubmitted manually).
    Now both `*l40s*` and bare `ci-training` resolve correctly.

(C) docs/superpowers/plans/...sp13...md — Layer B section expanded
    with concrete codebase locations discovered during P0a:
    - aux_heads_kernel.cu, aux_heads_loss_ema_kernel.cu locations
    - aux_nb_label_buf populated as column 0 of next_states (log_return)
    - F1/F2 regression history note (don't alias the label buffer)
    - aux_pred_to_isv_tanh_kernel.cu is a P0a placeholder per its own
      header — Layer B should rewrite to read softmax logit-diff
    - dir_acc kernel + oracle tests need softmax-read updates
    - Layer B + P0b combined rationale post-P0a empirics

Saves the next implementer ~30 min of re-investigation.
