Create shared baseline_common/metrics.rs module that registers all 18
dashboard-expected metrics (11 gauges, 5 counters, 2 histograms) and
spawns a lightweight HTTP metrics server on port 9094.
Instrument train_baseline_supervised and train_baseline_rl with:
- Epoch progress, training/validation loss gauges
- Checkpoint save timing, size, and failure counters
- NaN/gradient explosion detection counters
- Data loading latency histograms
- Active workers lifecycle (1 on start, 0 on exit)

Remove artificial swarm_size cap from plan_hyperopt() that limited
concurrent trials to n_particles (default 20). Now concurrency is
purely VRAM-driven with a hardware cap of 128 threads.
optimize_parallel() auto-scales n_particles to match GPU budget:
- L4 24GB: ~65 concurrent DQN trials (was 20)
- H100 80GB: 128 concurrent DQN trials (was 20)
- CPU/small GPU: falls back to configured n_particles
max_trials scales proportionally to ensure 3+ PSO iterations
for convergence with larger swarms.

Auto-detect now considers both CPU count and GPU VRAM when choosing
concurrent trial count. Prevents OOM on smaller GPUs.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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

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

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

evaluate_supervised looked for checkpoints at {models_dir}/{model}_fold{N}_best
but training saves to {models_dir}/{model}/{model}_fold{N}_best (model subdirectory).
Also saves NormStats JSON per fold during training so evaluation uses
training-time normalization instead of computing from test data (data leakage).

New evaluate_supervised binary runs walk-forward inference on supervised
model checkpoints (TFT, Mamba2, etc.), converts directional predictions
to trading signals, and computes Sharpe/MaxDD/WinRate/DirAccuracy.
CI changes:
- train-validate-dqn → train-validate-rl (trains+evals DQN+PPO)
- train-validate-tft now runs evaluate_supervised after training
- web/api fallback rules added to train-validate and deploy stages
- evaluate_supervised added to compile-services and Docker images

- 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)

The training binary creates flat [batch, 51] feature vectors (one per
bar), but TFTConfig::default() had sequence_length=50, making the
adapter expect [batch, 51*50=2550]. Set sequence_length=1 and
prediction_horizon=1 to match the actual point-wise sample format.

TFT create_model used TFTConfig::default() values for num_known_features(10)
and num_unknown_features(210) totaling 220, but input_dim was 51 from the
feature extractor. Set both explicitly: known=0, unknown=feature_dim.
S3 uploader now uses path-style requests (required for Scaleway S3) and
explicitly passes AWS credentials from env vars instead of relying on the
instance metadata credential provider (unavailable on Kapsule).
Also fix runner tags lost during session (kapsule, rust, docker restored).

Extend ml_training_service to dispatch GPU training jobs as K8s batch/v1
Jobs, collect results via a Rust sidecar uploader, and support model
promotion with operator approval via fxt CLI.
- K8s dispatcher creates Jobs on gpu-training pool with native sidecar
- training_uploader crate: watches DONE/FAILED marker, uploads to S3,
reports completion via ReportJobCompletion gRPC
- PromotionManager compares metrics, queues better models for approval
- 4 new proto RPCs: ReportJobCompletion, ListPendingPromotions,
ApprovePromotion, RejectPromotion
- fxt commands: train start, model list/approve/reject
- Training binaries write DONE/FAILED markers + metrics.json
- Dockerfile, K8s job template, and CI pipeline updated
- StartTraining gracefully falls back to in-process when outside K8s
- 27 new tests (16 service + 11 promotion), 141 total service tests pass

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.

These two files survived the 20-file consolidation in 022036cb.
Both are now fully superseded:
- train_ppo.rs → train_baseline_rl --model ppo
- train_mamba2.rs → train_baseline_supervised --model mamba2
Also updates entrypoint-generic.sh usage examples to reference
the unified binaries (train_baseline_rl, train_baseline_supervised).
