Three fixes from spec review:
1. diversity_entropy returns -0.1 penalty (threshold < 1.0) instead of raw entropy
2. barrier_done included in episode termination (barrier hit ends episode)
3. step_in_episode counter resets properly on mid-loop episode reset

Replace all `.to_string().parse::<f32/f64>()` patterns with
`num_traits::ToPrimitive` methods (`.to_f32()`, `.to_f64()`).
Each string roundtrip heap-allocated per conversion — fatal in
DQN hot loop (300K+ bars × epochs). Decimal stays as canonical
financial type; conversions happen at GPU/float boundaries only.
Also fixes blocking_read() in async context (risk_integration.rs).

P2-C reversal/cash warns fire thousands of times per hyperopt trial
during backtest simulation. Also removes stale Kelly patch file (already
applied).

These fire every training step when portfolio isn't populated yet —
extremely noisy during hyperopt with parallel trials.

The previous "auto-detect" logic forced CPU which was wrong — GPU is
faster for forward/backward even with parallel trials (DQN/PPO use
<350MB of 24GB VRAM across 7 threads).
Changes:
- Remove --device flag, always require CUDA GPU
- Add DQNTrainer::new_with_device() to share CUDA context across trials
- Propagate hyperopt device to internal DQN trainer (was ignoring it)
- PPO/DQN adapters error on missing GPU instead of silent CPU fallback
- Downgrade batch-size clamping from warn to debug

DQN/PPO networks are tiny (3 layers × 128 neurons). Running parallel
hyperopt on GPU wastes cores because CUDA context serializes across
threads — 5 trials on L4 only used 2000m of 6000m requested CPU.
Changes:
- Add --device flag to hyperopt_baseline_rl (auto/cpu/cuda)
- Auto mode forces CPU for parallel runs (no CUDA contention)
- CPU mode uses all available cores (no 2-core reserve)
- Add with_device() builder to DQN/PPO hyperopt trainers
- Downgrade "portfolio value <= 0" and GPU utilization warnings
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Portfolio value <= 0 during early exploration is expected behavior,
not a warning. GPU memory utilization advisory is informational.

Enable concurrent trial evaluation for DQN/PPO hyperparameter
optimization via clone-per-particle pattern — each PSO particle
clones the trainer and trains independently, replacing the previous
Arc<Mutex> serialization bottleneck. On L4 (8 vCPU) this yields
~4-5x throughput improvement.
Changes:
- DQNTrainer/PPOTrainer: Clone with Arc<AtomicUsize> trial counter
- DQNTrainer: replace unsafe mutable aliasing with Arc<Mutex> for
best_trial tracking
- ArgminOptimizer: add optimize_parallel() with ParallelObjectiveFunction
and scoped-thread LHS evaluation
- CLI: --parallel 0 (auto-detect CPUs-2), --initial-capital 35000,
--tx-cost-bps 0.1 (IBKR ES all-in)
- CI: both hyperopt jobs use --parallel 0 + IBKR ES cost defaults

train_from_parquet and load_training_data_from_parquet had zero
callers — TFT hyperopt uses train_from_bars via DBN data.
Also removes unused NormalizationParams struct from this module.

Feature vectors are [f64; 51] after WAVE 10 (Proxy OFI removal):
[0..5] static, [5..15] known, [15..51] unknown (36 features)
Old code used fv[15..54].min(fv.len()) which silently produced 36
features per step but expected 39 in Array2 shape → ShapeError.

Three critical stability fixes for PPO training:
1. Gradient clipping: Added clip_grads() that scales gradients by
max_norm/norm when L2 norm exceeds max_grad_norm (0.5). Previously
the code only logged a warning — gradient norms of 27-171x above
the threshold were applied raw to weights, causing divergence.
Fixed in all 8 locations across PpoTrainer (6) and ContinuousPPO (2).
2. Return normalization: Value loss now normalizes returns to N(0,1)
before computing MSE. Raw cumulative returns (±1000s) caused enormous
value gradients that destabilized the critic network.
3. Hyperopt search space: Tightened value LR upper bound from 1e-3 to
1e-4 (1e-3 is documented unstable), policy LR from 1e-3 to 3e-4.
Also fixed LSTM path where optimizer.step() ran BEFORE gradient norm
check — now clip → step (not step → warn).

The adaptive-strategy crate (~28K lines, 22 source files) was an orphaned
framework with zero external consumers. Its only valuable piece — ensemble
uncertainty quantification — has been ported to ml/src/ensemble/confidence.rs.
Ported: ConfidenceAggregator, UncertaintyQuantifier, ReliabilityScorer,
IntervalCombiner, DisagreementTracker + all config/output types. Removed
gratuitous async from pure-math methods. 6 tests (4 ported + 2 edge cases).

Extend hyperopt infrastructure to support all 10 ML models (DQN, PPO +
8 supervised). Previously only TFT and Mamba2 had hyperopt trainers.
- Add HyperparameterOptimizable impl for Liquid, TGGN, TLOB, KAN, xLSTM, Diffusion
- Create shared_data.rs with common data prep utilities (build_flat_pairs,
build_sequence_pairs, write_trial_result_json)
- Extend hyperopt_baseline_supervised binary to dispatch all 8 models
(individual, "both" for tft+mamba2, "all" for all 8)
- Add CI jobs: 7 train-validate + 10 hyperopt jobs for all models
- Fix DiffusionMetrics NaN default, XLSTMMetrics serde, safe indexing

The validate() method called loss.to_scalar::<f64>() on an F32 tensor,
causing "unexpected dtype, expected: F64, got: F32" at runtime.
Add .to_dtype(F64) before scalar extraction, matching the pattern
used in all other TFT gradient/loss code paths.

These tests assert sub-millisecond latency thresholds that only hold
with opt-level=3. Now that dev/test builds use opt-level=0 (correct),
mark them #[ignore] so they run only via `cargo test --release`.

- Add dimension validation in DQN, PPO, Mamba2, TGGN, TLOB, Liquid,
KAN, xLSTM, Diffusion constructors (fail-fast on zero-dim inputs
that would cause CUDA_ERROR_INVALID_VALUE at runtime)
- Add num_unknown_features > 0 guard to TFT (temporal input required)
- Fix 12 dead-code/unused warnings in test compilation
- Remove opt-level=3 and codegen-units=1 from target rustflags
(was forcing O3 + single-thread codegen on dev/test builds)
- Remove hardcoded jobs=16 cap (cargo now auto-detects CPU count)
- Switch linker to clang+lld (2-5x faster linking)

CUDA cannot handle linear layers with zero input dimensions.
When num_static_features=0 or num_known_features=0, the
VariableSelectionNetwork constructor creates linear(0, 0, ...)
which triggers CUDA_ERROR_INVALID_VALUE on GPU.
- Make static/future VSN and GRN encoder fields Option<T>
- Skip layer creation when feature count is 0
- Forward pass skips absent feature paths gracefully
- Trainable adapter creates empty placeholder tensors
- Add cilium CNI toleration to training job template and runner
All 103 TFT tests pass.

The tensor-based log_probs() had an inverted sign on the squared
difference term: .sub(&(x * -0.5)) = +0.5*x² instead of -0.5*x².
This caused actions far from the mean to get higher log probabilities.
Also fix test assertions: continuous log probability densities CAN
be positive (when σ is small and action is near mean), unlike
discrete log probabilities which are always <= 0.

Adds a parent/child GitLab CI pipeline for ML model training:
- Generator script produces per-model hyperopt/train/evaluate jobs
- Parent pipeline (.gitlab-ci-training.yml) with manual trigger
- NFS-backed ReadWriteMany PVC for shared training outputs
- Hyperopt params wired into training binaries (DQN, PPO, TFT, Mamba2)
- Shared DBN loader eliminates duplicate code across hyperopt adapters
- Supervised hyperopt unified to DBN data (was parquet-only)
Pipeline: hyperopt (4 models) → train (10 models) → evaluate ensemble

Split the build pipeline: one compile-services job builds all 8 service
binaries with PVC-backed sccache, saves as artifacts. Then 9 Kaniko jobs
just package pre-built binaries into slim runtime images (~30s each).
Before: 9 parallel Kaniko jobs each doing full cargo build --release
(~20min each, no sccache, 9x duplicated dep compilation)
After: 1 compile job with sccache (~5min cached) + 9 package jobs (~30s)
- Add compile stage between test and build
- Add Dockerfile.runtime (minimal debian + pre-built binary)
- Add Dockerfile.web-gateway-runtime (Node dashboard + pre-built binary)
- Keep Dockerfile.training via Kaniko (needs CUDA dev image for H100)
- Remove all SCCACHE_BUCKET build-args from service builds
- Use dir:// context for Kaniko (only sends build-out/ dir, not full repo)

Mass cleanup of crates/ml/:
- Delete 121 dead/broken/superseded example files (-44,098 lines)
- Delete 6 QAT test files (-4,201 lines) — QAT is disabled at runtime
(trainer.rs falls back to FP32 with warning)
- Delete 2 stale markdown files in examples/
- Delete orphaned src/bin/train_tft.rs (unimplemented stub)
- Clean up Cargo.toml: remove stale [[example]] entries, add missing ones
- Fix stale binary references in log_size_test.rs
- Add infra consistency test (35 checks across Dockerfile/train.sh/Cargo.toml)
Remaining examples (7): train_baseline_rl, train_baseline_supervised,
evaluate_baseline, hyperopt_baseline_rl, hyperopt_baseline_supervised,
download_baseline, cuda_test
All 2390 lib tests pass. All examples compile. 35/35 infra checks pass.
