Web dashboard build now uses node:22-slim with inline rclone install
instead of a custom Kaniko-built image. This removes 1 Kaniko build
from the prepare stage, reducing pod scheduling contention.
Only 2 runtime images needed: CPU (foxhunt-runtime) and GPU
(foxhunt-training-runtime). Binary selection is via K8s command.

The GPU experience collection kernels (dqn_experience_kernel.cu,
ppo_experience_kernel.cu) use cudarc::nvrtc::compile_ptx() at runtime.
Without libnvrtc.so the kernel compile fails silently and falls back to
CPU experience collection. Adding cuda-nvrtc-12-4 (~30MB) enables full
GPU-accelerated experience collection.

Both images now use identical cuda:12.4.1-cudnn-runtime base, so maintaining
two separate Dockerfiles and build jobs was wasteful. Single image contains
all 7 training binaries, halving registry storage and Kaniko build time.

candle's CUDA backend links against libcudnn.so.9 for kernel operations.
Switch training-rl base from cuda:12.4.1-runtime to cuda:12.4.1-cudnn-runtime.

RL models (DQN/PPO) only need basic CUDA runtime (~2GB), while supervised
models need cuDNN (~4GB). Splitting saves ~2GB pull time per RL job.
Rename the L4 GPU pool from ci-compile to ci-rl to reflect its actual use.
Add DaemonSet image pre-puller to cache training images on GPU nodes.

The compile-services stage outputs binaries to build-out/services/ but
the web-gateway Dockerfile still referenced the old build-out/ path.

Based on rust:1.89-slim-bookworm (~2-3GB vs ~8GB CUDA devel).
Same toolchain: mold 2.35, protoc 28.3, sccache 0.10, clang, lld.

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

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

Deploy was silently failing — bitnami/kubectl image lacks scw CLI
needed by Kapsule kubeconfig credential plugin. Now uses infra-runner
(has scw), installs kubectl inline until image is rebuilt. Adds
cluster-info check before deploy and proper error reporting per service.

Training image was recompiling from scratch inside Kaniko (~16+ min)
without sccache. Now training binaries are built in compile-services
with --features ml/cuda and PVC sccache (warm cache from service
binaries), then packaged into a CUDA runtime image (~30s).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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)

- Add --cache=true --cache-repo to all 12 Kaniko builds
- Cache Docker layers in Scaleway CR (rg.fr-par.scw.cloud/foxhunt-ci/cache)
- Add Docker Hub auth to devcontainer + infra-runner prepare jobs
- First build populates cache; subsequent builds skip base image pulls

sccache 0.8+ (opendal backend) requires AWS_REGION, not just
AWS_DEFAULT_REGION. Also set SCCACHE_REGION as belt-and-suspenders.

- Update COPY paths in all 3 Dockerfiles for crates/bin/services/testing layout
- Migrate service image builds from internal GitLab registry to SCW CR
- Update Kaniko auth to use SCW credentials (nologin + SCW_SECRET_KEY)
- Remove --insecure-registry flags (SCW CR is HTTPS)

The backtesting crate links libcuda.so.1 at runtime (via candle CUDA).
GPU-less CI nodes need the stub library so binaries can load, but
model_loader tests that actually use CUDA must be skipped. These will
run on gpu-training nodes separately.

The backtesting crate dynamically links to libcuda.so.1 via candle.
NVIDIA CUDA dev images include stubs at /usr/local/cuda/lib64/stubs/
but only as libcuda.so (not .so.1). Create the symlink both in the
Dockerfile (for future builds) and inline in the test script (for
the current image).
