gamma_update kernel computes health-coupled gamma from ISV[LEARNING_HEALTH=12]: gamma_eff = gamma_min + (gamma_base - gamma_min) * health. Single-thread cold-path kernel writes ISV[GAMMA_EFF_INDEX=43]. GammaMonitor is a read-only observer exposing gamma_eff, health, fire_rate. Consumer migration: fill_gamma_buf and IQL gamma computation now read ISV[GAMMA_EFF_INDEX] via read_isv_signal_at (pinned, zero-copy). Training loop passes hyperparams.gamma as gamma_base to the kernel. Deleted: apply_adaptive_gamma method (GpuDqnTrainer + FusedTrainingCtx delegates), set_adaptive_gamma method, adaptive_gamma field (GpuDqnTrainer + DQNTrainer), last_gamma_eff cached field + last_gamma_eff() delegate. StateResetRegistry entry for adaptive_gamma removed (field gone). Smoke test generalization.rs updated to check config gamma_base instead of deleted adaptive_gamma field. Tests: 3 monitor unit tests pass. cargo check -p ml at 8-warning baseline. Plan 1 Task 10. Spec §4.C.6 (2026-04-24 revision). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
