Documented here for completeness; the SP5 brainstorm flagged this as a question. Code inspection resolved it.
### Layer A close-out: host-EMA → GPU sweep migration
Migrate 5 remaining host-aggregated EMA sites to GPU per `feedback_no_cpu_compute_strict`:
- `training_sharpe_ema` — requires per-step PnL aggregation on GPU
- `max_dd_ema` — same
- `gamma_blend` — host-aggregated eval result, port to GPU
- `LearningHealth` composition pipeline — multi-step host arithmetic, port to GPU
- `HealthEmaTrackers` — q_gap_ema + q_var_ema + grad_norm_ema host-side EMAs
Substantial: requires per-step trade-PnL aggregation kernel + multi-step composition kernel. Estimated 600-1000 LOC for this layer alone.
