+# Self-Improving Training Loop Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Transform the epoch-end validation backtest into an active training signal. 9 enrichment steps extract ground truth from greedy eval and auto-tune the next epoch's training — epsilon, gamma, per-branch LR, replay weights, Q-value calibration, ensemble gating. Zero hardcoded schedules.
+
+**Architecture:** All enrichments are Rust code in the training loop, processing data already produced by the existing `compute_validation_loss` → `WindowMetrics`. No new CUDA kernels needed (all enrichments operate on CPU-side metrics after DtoH readback). Enrichments write to existing pinned device-mapped scalars or modify replay buffer priorities via existing PER infrastructure. ~215 lines of Rust across 2 files.
+
+**Tech Stack:** Rust 1.85, existing GpuBacktestEvaluator + WindowMetrics + PER infrastructure
+
+---
+
+## File Structure
+
+All enrichments live in ONE new file + modifications to the training loop:
+
+- **Create:** `crates/ml/src/trainers/dqn/trainer/enrichment.rs` — all 9 enrichment functions
+- **Modify:** `crates/ml/src/trainers/dqn/trainer/training_loop.rs` — call enrichments after validation
+- **Modify:** `crates/ml/src/trainers/dqn/trainer/mod.rs` — add enrichment state fields + module declaration
+
+The enrichment module is a pure function library: each enrichment takes eval data + current state, returns adjustments. No CUDA, no GPU memory management. Clean separation from the training loop.
+
+---
+
+## Task 1: Enrichment State + Module Skeleton
+
+Create the enrichment module with state struct and stub functions.

+## Task 6: Build Verification + Smoke Test
+
+**Files:**
+- Modify: `crates/ml/src/trainers/dqn/smoke_tests/generalization.rs`
+
+- [ ] **Step 1: Add enrichment verification to smoke test**
+
+In the generalization smoke test, after training completes, verify enrichment state was updated:
+
+```rust
+    // Self-improving enrichment state verification
+    info!("  Enrichment epochs: {}", trainer.enrichment.enrichment_epoch);
+    info!("  Enrichment epsilon: {:.4}", trainer.enrichment.adaptive_epsilon);
+    info!("  Enrichment q_correction: {:.3}", trainer.enrichment.q_correction);
+    info!("  Enrichment branch_lr: {:?}", trainer.enrichment.branch_lr_scale);
+    assert!(trainer.enrichment.enrichment_epoch > 0,
+        "Enrichment should have run at least once");
+    assert!(trainer.enrichment.adaptive_epsilon > 0.0,
+        "Adaptive epsilon should be positive");
+```
+
+- [ ] **Step 2: Full compilation check**
+
+```bash
+SQLX_OFFLINE=true cargo check -p ml 2>&1 | tail -5
+```
+
+- [ ] **Step 3: Run smoke test**
+
+```bash
+SQLX_OFFLINE=true FOXHUNT_TEST_DATA=test_data/futures-baseline cargo test -p ml --lib -- test_generalization_components_smoke --include-ignored --nocapture 2>&1 | tail -20
+```
+
+- [ ] **Step 4: Run compute-sanitizer**
+
+```bash
+FOXHUNT_TEST_DATA=test_data/futures-baseline compute-sanitizer --tool memcheck --print-limit 5 target/debug/deps/ml-* "test_generalization_components_smoke" --test-threads=1 --include-ignored 2>&1 | grep "ERROR SUMMARY"
+```
+
+Target: 0 errors.
+
+- [ ] **Step 5: Final commit**
+
+```bash
+cd /home/jgrusewski/Work/foxhunt && git add -A && git commit -m "feat: self-improving training loop complete — 9 enrichments integrated
+
+E1: Q-value reality check (bias correction from eval)
+E2: Adaptive epsilon (performance-driven exploration)
+E3: Dynamic gamma (from profitable trade durations)
+E4: Trade autopsy (per-branch LR scaling)
+E5: Ensemble agreement (auto-tune epistemic threshold)
+E6: Winner distillation (boost top trades in replay)
+E7: Hindsight labels (correct actions for losers)
+E8: Curriculum weights (oversample failure segments)
