Compile and test jobs run on ci-compile (L4) without nvidia RuntimeClass
since they only need CUDA headers, not GPU access. The nvidia-smi call
was failing because the GPU device isn't passed through without the
RuntimeClass.
Now nvidia-smi failure is non-fatal for compile/test, with CUDA compute
cap defaulting to 89 (L4) for sccache partitioning. Training jobs still
require nvidia-smi to succeed (they need actual GPU access).

When a commit doesn't touch source code (e.g. infra-only changes), the
changes: filters exclude build jobs from the pipeline. Without
optional: true, downstream jobs (train, deploy) fail with "needs X job
but X does not exist in the pipeline".
Now all needs entries use optional: true so pipelines succeed even when
upstream jobs are filtered out by changes: rules.

Setting runtime_class_name = "" causes Kubernetes to reject pod creation
with "resource name may not be empty". Omitting it entirely means no
runtimeClassName on pod spec by default; GPU jobs override via
KUBERNETES_RUNTIME_CLASS_NAME CI variable.

L4 ci-compile node was failing with 'no runtime for nvidia' because
fresh nodes take time to install nvidia drivers. Kaniko builds don't
need GPU at all. Now only Rust compile/test and training jobs request
nvidia RuntimeClass via KUBERNETES_RUNTIME_CLASS_NAME CI variable.

Training and hyperopt jobs now capture exit codes and continue to
evaluation step regardless. Job still fails if training failed, but
eval output/artifacts are always available for debugging.

Check stage was just echoing "skipped" but still spun up an L4 pod.
Test and compile-services now start immediately (needs: []).
Infra-plan and drift-check moved from check→test stage.

- compile-services now depends on check (not test), running in parallel
with test stage — saves ~10 min from critical path
- Runner concurrent bumped 4→10 so all 9 Kaniko builds run simultaneously
- Runner default resources lowered (500m/1Gi) for lightweight Kaniko jobs;
Rust compile/test/training override via KUBERNETES_*_REQUEST CI vars

All K8s nodeSelectors, CI config, runner config, monitoring docs, and
smoke tests now reference the new pool names provisioned by terragrunt.

Split GPU workloads across two pools:
- ci-compile (L4-1-24G): for cargo check/test/build — cheaper, same
CUDA CC 8.9 as L40S, sufficient 24GB VRAM for compilation
- ci-build (L40S-1-48G): for hyperopt + training — 48GB VRAM needed
for large model training batches
Runner defaults to ci-compile; training jobs override to ci-build
via KUBERNETES_NODE_SELECTOR. Both pools autoscale to zero when idle.

Use KUBERNETES_CPU_REQUEST/LIMIT CI variables to differentiate:
- Compile jobs (.rust-base): 7000m/7800m — CPU-bound, benefits from
all cores for parallel Rust compilation + linking
- Training jobs (.train-validate-base): 2000m/3500m — GPU-bound,
low CPU allows 2 concurrent training jobs on same node
Previously all jobs shared 3500m/7000m defaults, wasting half the
L40S node's CPU during compilation.

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).

clang's -fuse-ld=mold searches for "ld.mold" binary, not "mold".
Previous wrapper created /usr/local/bin/mold which clang never finds.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
lld checks argv[0] to determine its mode (ld.lld, ld64.lld, etc).
A symlink named ld.mold pointing to ld.lld still invokes with
argv[0]="ld.mold" which lld rejects as "generic driver".
Replace symlink with a wrapper script that explicitly invokes ld.lld,
so clang -fuse-ld=mold finds /usr/local/bin/mold and it delegates
correctly to the ELF linker.

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).

The .cargo/config.toml now uses -fuse-ld=mold, but the CI builder image
hasn't been rebuilt yet with mold. Add a symlink fallback in .rust-base
before_script: if mold isn't found, symlink ld.mold → ld.lld so builds
continue working until the builder image is rebuilt.

Add Cargo profile `dev-release` (opt-level=2, thin LTO, 16 codegen-units)
for ~3-5x faster compile vs full release. Activate by setting DEV_RELEASE=true
in pipeline variables — skips check stage and uses fast profile.
- Move profile definitions from .cargo/config.toml to Cargo.toml (config.toml
silently ignores [profile.*] blocks — they were dead code)
- Add hft and bench profiles to Cargo.toml (were only in config.toml)
- compile-services now selects profile via $DEV_RELEASE env var
- test stage uses optional check dependency (runs without check in dev mode)

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

Adds hyperopt-ppo job (manual, 4h timeout) that runs:
1. PSO hyperopt (20 trials, 15 epochs each) to find optimal PPO params
2. Full training with best params
3. Walk-forward evaluation with Sharpe/MaxDD/WinRate metrics
Artifacts: ppo_hyperopt_results.json + ppo_eval_report.json (90 days)

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).

The 10μs threshold is too tight for shared K8s pods with noisy-neighbor

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

When changes: glob evaluation fails (known GitLab CE bug) or when only
CI config is modified, web/API-triggered pipelines now always run all
code stages unconditionally. This also serves as the manual override
for pipeline #110 which silently dropped all jobs.

Add evaluate_baseline after DQN training smoke test so we get Sharpe,
MaxDD, WinRate, and ProfitFactor in the pipeline artifacts. Remove
.gitlab-ci.yml from changes: filters so CI-config-only pushes no longer

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.

- 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)
