L40S smoke at SP5 Layer B HEAD (3ad5e011b) failed in 9.4s at first
fold-reset boundary with:
ERROR: fold-reset 'sp5_atom_v_center': StateResetRegistry reset
dispatch: unknown name 'sp5_atom_v_center'.
Every SP5 Layer A task added RegistryEntry blocks but none added the
matching dispatch arms in reset_named_state. Runtime validator catches
this on first fold boundary, crashing all 3 folds before training runs
(0/3 checkpoints saved). Local unit tests verified slot layouts but
never exercised the fold-reset dispatch path — gap masked through
Layer A close-out.
Adds 21 dispatch arms covering all SP5 Layer A FoldReset entries:
Pearl 1: sp5_atom_v_center / v_half / headroom / clip_rate
shared: sp5_branch_entropy / q_var_per_branch
wiener: sp5_wiener_state (no-op — sp4 arm covers full buffer)
Pearl 3: sp5_noisy_sigma / sigma_fraction
Pearl 2: sp5_budget_c51 / iqn / cql / ens / flatness
Pearl 4: sp5_adam_beta1 / beta2 / eps + sp5_grad_prev_buf
Pearl 5: sp5_iqn_tau
Pearl 8: sp5_trail_dist_per_dir
Pearl 1-ext: sp5_atom_num_atoms
Pearl 6 (slots 280..286) intentionally absent — those slots are
cross-fold-persistent (the whole point of A6 per
project_magnitude_eval_collapse_kelly_capped).
Each ISV-range arm zeros its slot range to fire Pearl A's first-
observation sentinel on the new fold's first producer launch.
sp5_grad_prev_buf calls a new reset_sp5_grad_prev_buf bulk-zero
method on GpuDqnTrainer (mirrors reset_sp4_clamp_engage_counters).
sp5_wiener_state is no-op since reset_sp4_wiener_state already
bulk-zeros the full wiener_state_buf [0..543) which includes the SP5
producer block at offsets [213..543).
cargo check + cargo test --lib (sp4+sp5+state_reset_registry: 13/13
pass) both clean. Smoke re-deployment pending.
