Phase E.1 Task 11. Two pub(crate) launchers expose the kill-criteria
producer (Task 9) and Munchausen target augmentation (Task 10) for use
by future trainer integration:
launch_phase_e_kill_criteria(stream, kernel, q_values_dev, action_counts_dev,
scalar_inputs_dev, isv_dev, batch, n_actions,
scratch_out_dev)
→ kicks the kill_criteria producer; caller chains apply_pearls_ad_kernel
(n_slots=4, isv_idx_base=ALPHA_ISV_BLOCK_LO=539) to smooth into slots
539..542 via Pearl A bootstrap + Pearl D Wiener-α.
launch_phase_e_munchausen_target(stream, kernel, q_next_dev, q_current_dev,
actions_dev, rewards_dev, dones_dev,
gamma, alpha_m, tau, log_clip_min,
target_out_dev, batch, n_actions)
→ one-thread-per-sample target augmentation; α_m/τ/log_clip_min are
scalar args so a downstream ISV-driven controller can tune them.
Plan deviation: Task 11 plan-spec said "replace hardcoded n_step=32,
gamma=0.999 literals" but grep across gpu_dqn_trainer.rs found ZERO such
literals — the trainer already reads gamma via read_isv_signal_at(
GAMMA_DIR_EFF_INDEX) and epsilon via read_isv_signal_at(AUX_TRUNK_EPS_
INDEX). The actual E.1 deliverable was Rust launchers for the new
cubins, which this commit lands.
Both launchers follow the launch_apply_pearls pattern in
sp4_wiener_ema.rs — pre-loaded CudaFunction as parameter, u64 device
pointers, debug_assert! guards.

Tested via `cargo test -p ml --lib phase_e_kernels` — 1 compile-witness
passes. Real GPU integration test in Task 12.
