rclone (~50 MB installed) is not used by any Argo step that runs in
ci-builder-cpu. The only Argo step that does use rclone
(build-web-dashboard) runs in node:22-alpine and apk-installs rclone
itself. Removing here saves an unused ~50 MB layer in every
ci-builder-cpu pull on every CI compile pod cold-start.
Tools deliberately KEPT despite the original task suggestion to remove
them:
- terragrunt + tofu — used by terragrunt-apply step in
ci-pipeline-template.yaml (runs in ci-builder-cpu)
- kubectl — used by apply-argo-templates step in
ci-pipeline-template.yaml (runs in ci-builder-cpu)
Removing those would break those pipeline steps.
Expected impact: ~50 MB image size reduction, ~3-7 sec cold-pull
savings per compile pod. Smaller than the original ~250 MB estimate
because terragrunt/tofu/kubectl had to stay.
Validation: visually inspected Dockerfile syntax (no docker daemon
available locally). Grepped infra/k8s/argo/*.yaml for rclone usage —
only build-web-dashboard (node:22-alpine) references it.

ML Models
Four production model architectures on Candle v0.9.1 with CUDA:
- DQN Rainbow -- Deep Q-Network with prioritized replay, dueling heads, noisy nets
- PPO -- Proximal Policy Optimization with GAE and LSTM policies
- TFT -- Temporal Fusion Transformer for multi-horizon forecasting
- Mamba2 -- State space model for sequence prediction
Each model has a standalone trainer and a UnifiedTrainable adapter for the hyperopt pipeline.
Infrastructure
- Git: Gitea at
git.fxhnt.ai(Tailscale-only), Scaleway DEV1-S - Observability: OpenTelemetry OTLP (env
OTEL_EXPORTER_OTLP_ENDPOINT) - Database: PostgreSQL with SQLx offline mode for CI
