End-to-end test for the kernel COMPOSITION that the H=600 DQN smoke
(Task 12 proper) will use at each rollout boundary:
t+0 alpha_kill_criteria_compute_kernel → scratch[0..4]
t+1 apply_pearls_ad_kernel(n_slots=4) → ISV[539..543]
The two prior alpha_kernels smokes (munchausen + kill_criteria) validated
kernels in isolation. This smoke validates the COMPOSITION on the same
stream — failures here are different (stream-ordering, Pearls index base,
Wiener offset base, scratch visibility) and would silently break Task 12.
Two iterations with stationary synthetic inputs:
Iter 1 (Pearl A bootstrap)
prev_x_mean=0 AND x_lag=0 → ISV[539..542] populated with raw scratch
observations = [0.2041, 0.8980, 1.0670, 0.1] within 0.01 tolerance.
Anchor slots 547/548 remain at Task 7c values (-5185, 4953).
Iter 2 (Pearl D stationary)
dx_mean = dx_step = 0 → α* = 0 → ISV unchanged from iter 1 within
1e-4. Stationary signal stays at the bootstrap value.
Test would catch:
- Producer's scratch write not visible to applicator (stream-ordering)
- Wrong Pearls isv_idx_base / wiener_offset_base
- Pearl A sentinel detection broken (formula yields 0 at t=0)
- Wiener state corruption (iter 2 drifts from iter 1)
Reuses launch_apply_pearls from sp4_wiener_ema.rs (pub(crate)). Helper
fn run_chained_iter factors the producer→applicator sequence so the two
iterations are byte-identical apart from the Wiener state's evolution.
`cargo test -p ml --lib alpha_kernels`: 4 pass (compile witness + 2 prior
GPU smokes + this chained smoke) on RTX 3050 Ti in 1.89s total. Audit doc
docs/isv-slots.md updated per Invariant 7.
Remaining Task 12 work (full H=600 DQN trainer integration with this
pipeline at rollout boundaries) is queued for a dedicated session.
