Two 9-quarter precompute_features runs OOM-killed on the existing
ci-compile-cpu pool (POP2-HC-32C-64G, 56Gi cgroup limit):
- train-wq8b8: exit 137 ~12s after "OFI computed" at ~57Gi
- train-2l6p4: exit 137 ~12s after "OFI computed" at ~52Gi peak
(despite the into_iter + drop(feature_vectors) +
normalize_in_place refactors landed in a27cb40a9 + 623ebfcf7,
which trimmed ~12GB of avoidable retention)
The remaining ~52-60GB peak is the irreducible working set at the
post-OFI / pre-alpha-pipeline step:
- 9-quarter MBP-10 snapshots (~10GB)
- 199M front-month trades as Mbp10Trade (~13GB)
- 17.8M bars × features + targets + OFI buffers (~14GB)
- alpha_snapshots (move-handoff from all_snapshots, ~10GB)
- feature/target Vecs (~7GB) + Rust allocator overhead
Adds a dedicated high-memory pool sized for this rare path:
- New scaleway_k8s_pool.ci_compile_cpu_hm (POP2-HM-32C-256G,
32 vCPU + 256GB RAM) with size=0 + min_size=0 autoscaling. Costs
zero when idle; autoscaler provisions one node when a pod targets
`nodeSelector: ci-compile-cpu-hm`.
- New variables: enable_ci_compile_cpu_hm_pool,
ci_compile_cpu_hm_type (default POP2-HM-32C-256G),
ci_compile_cpu_hm_max_size (default 1).
- terragrunt.hcl: enable the pool, max_size=1.
- train-template.yaml: ensure-fxcache nodeSelector pinned to
ci-compile-cpu-hm; memory limit raised 56Gi → 200Gi. The
ci-compile-cpu pool stays as the standard CI compile target for
ensure-binary + every other CPU-heavy task.
Apply with:
cd infra/live/production/kapsule
terragrunt apply -target=module.kapsule.scaleway_k8s_pool.ci_compile_cpu_hm
kubectl apply -n foxhunt -f ../../../../infra/k8s/argo/train-template.yaml

Scaleway Kapsule GPU nodes need NVIDIA driver DKMS compile on cold
start (~15 min). Setting min_size=1 keeps the node warm between runs.
Scale to 0 manually when done training for the day.

- Added scaleway_vpc_public_gateway + DHCP + gateway_network to TF
(was manually created, now codified with push_default_route=true)
- Added scripts/safe-node-replace.sh — one-at-a-time with DNS verification
- Added dns-bootstrap-policy.yaml — incident documentation + recovery procedure
- Bastion enabled (port 61000) for emergency SSH access
Prevention: NEVER replace all nodes at once. Use safe-node-replace.sh.

- Add terragrunt-apply step to Argo CI pipeline (plan+apply on main push
when infra/live/ or infra/modules/ change)
- Bake OpenTofu 1.9.0 + Terragrunt 0.77.12 into ci-builder-cpu image
with SHA256 checksum verification
- Remove 3 ghost node pools (foxhunt, gitlab, h100-sxm8) from kapsule
module to match Scaleway reality
- Make terragrunt.hcl single source of truth (remove variable defaults)
- Fix GitLab TF state lock methods (POST/DELETE for HTTP backend)
- Harden PAT rotation: more retries, verification step, recovery docs
- Add weekly PAT expiry check CronJob (warns 14 days before expiry)

- Replace fragile `git fetch --depth=1 origin "$SHA"` (fails with short SHAs)
with `git clone --no-checkout --filter=blob:none` + `git checkout "$SHA"`
across all 3 Argo templates (5 clone blocks total)
- Upgrade CI compile pool from POP2-32C-128G to POP2-HC-32C-64G
(higher clock EPYC cores, 28% cheaper at €0.851/hr vs €1.18/hr)

Rename ci-training → ci-training-l40s, add H100/H100x2/H100-SXM/H100-SXM-8
pool resources (all autoscaling 0→1). Remove dev pool (DevPod on platform).

ci-rl pool was permanently disabled (enable_ci_rl_pool=false), all
training consolidated on ci-training (L40S). foxhunt-binaries S3
bucket was never created — binaries now deploy via shared PVC.
Also: deleted orphaned infra/live/production/ci-runner/ directory,
cleaned up stale Grafana ReplicaSets, recreated missing grafana PVC,
deleted orphaned Released PV, synced runner Helm configmap.

Applied terragrunt to recreate the L4 GPU pool with the correct name
`ci-rl` (was `ci-compile` due to immutable Scaleway pool names).
Updated all K8s manifests and comments to match. Removed the 3 stale
`moved` blocks from main.tf since the state renames are now applied.
Pool naming is now consistent across Terraform, Scaleway, and K8s configs:
- ci-compile-cpu (POP2-32C-128G) — CPU compilation
- ci-rl (L4-1-24G) — RL training / CUDA compile
- ci-training (L40S-1-48G) — supervised training + hyperopt
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.

Kapsule doesn't allow node-labels in kubelet_args. Instead, use the
auto-assigned k8s.scaleway.com/pool-name label that every node gets.
- Revert kubelet_args from Terraform (not supported)
- Switch runner node_selector: pool→k8s.scaleway.com/pool-name
- Update CI pipeline KUBERNETES_NODE_SELECTOR to match
- Helm upgraded both runners (CPU + GPU)
No more manual kubectl label after node scale-up.

Nodes from autoscaler now get pool=<name> labels automatically via
kubelet_args, eliminating the need to manually label nodes after
scale-up events.

GP1-L and PRO2-L both have 0/0 quota in fr-par-2. POP2-HC-32C-64G had
insufficient root disk (20GB). POP2-32C-128G with 100GB SBS root works.

Split runners into CPU (compile/build/deploy) and GPU (training):
- CPU runner: tags kapsule,rust,docker → ci-compile-cpu (32 vCPU, 64GB)
- GPU runner: tags kapsule,gpu → ci-compile (L4) or ci-training (L40S)
Changes:
- Add ci-compile-cpu Terraform pool (POP2-HC-32C-64G, autoscale 0-1)
- Set CARGO_BUILD_JOBS=30 to use all CPUs for Rust compilation
- Increase CPU request to 28000m/31000m (was 7000m/7800m on L4)
- Add docker tag to deploy/infra jobs for explicit CPU runner routing
- Update CI header with new pool routing documentation
Cost: EUR 0.85/h (vs EUR 1.1/h for L4) — cheaper AND 4x faster compile
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.

Services moved off L40S GPU node to always-on DEV1-M pool.
Single DEV1-M couldn't fit all services, so enable autoscaling
with max_size=2 to allow a second node when needed.

- Remove gpu-training (H100) and gpu-inference (L4) pool resources,
variables, and outputs from kapsule module — L40S handles all GPU work
- Switch public-gateway from hardcoded private_network_id to
dependency.kapsule.outputs.private_network_id

Create dedicated ci-build node pool (L4-1-24G, €0.75/hr) replacing
H100 (€3.50+/hr) for CI builds. H100 reserved for training only.
- Add ci-build pool to Terraform (L4-1-24G, scale-to-zero, fr-par-2)
- Update GitLab Runner to target ci-build pool with L4-sized limits
- Change CUDA_COMPUTE_CAP from 90 (H100) to 89 (L4) in CI
- Dockerfile.training keeps CUDA_COMPUTE_CAP=90 for H100 training

Scale-to-zero pools start with 0 nodes, so Terraform's default
wait_for_pool_ready=true always fails with "state warning, wants ready".

GP1-L (16 vCPU, 64GB), autoscaling 0→1, dedicated for dev pods.
Separate from CI (H100) and inference (L4) pools.

Remove orphaned `ci` pool (GP1-XS, 4 vCPU wasted — nothing scheduled to it).
Remove `ci-build` pool (GP1-M) — builds now run on gpu-training (H100-1-80G:
24 vCPU, 240GB, real CUDA). This eliminates the need for CUDA stubs,
separate test-gpu jobs, and ml crate exclusions.
Pool layout after:
always-on DEV1-M (core services, always on)
gitlab GP1-XS (GitLab CE + runner manager, always on)
gpu-training H100-1-80G (CI builds + ML training, scale-to-zero)
gpu-inference L4-1-24G (trading inference, scale-to-zero)
Build pod limits bumped to 16 vCPU / 64GB (from 6/12GB) to use H100 capacity.
Runner now has `gpu` tag — all tests including ml crate run in single job.

- Split single H100 GPU pool into two purpose-specific pools:
- gpu-training: H100-1-80G (€2.73/hr) for 10-model ensemble training
- gpu-inference: L4-1-24G (€0.75/hr) for cost-effective trading inference
- Add GPU taint controller DaemonSet that auto-taints new GPU nodes
with nvidia.com/gpu=true:NoSchedule to prevent non-GPU workloads
- Fix service log directory permissions with emptyDir volumes
(observability init fails creating /app/logs as non-root user)
- Increase postgres max_connections from 25 to 100
(7 services each requesting connection pools exhausted the limit)

- K8s API ACL restricted to Tailscale CGNAT (100.64.0.0/10) + admin IPs
- CI and GPU pools: min_size=0 with lifecycle ignore_changes on size
so autoscaler manages actual node count without Terraform drift
- Add harden.sh script for post-provisioning security lockdown
(ACL setup, exposed service check, bucket ACL verify, registry visibility)
- Update smoke-test.sh default region to fr-par
Security audit results:
- All services ClusterIP only (no LoadBalancer/NodePort)
- No Ingress resources
- Container registry: private
- S3 buckets: HTTP 403 on anonymous access
- Gitea: all ports closed on public IP (Tailscale-only via security group)
- Kapsule nodes: no open ports on external IPs
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- kapsule: cluster + 3 node pools (always-on, ci, gpu)
- object-storage: S3 bucket with 30-day sccache expiry
- registry: private Container Registry namespace
- secrets: JWT + DB password via Secret Manager
- block-storage: 100GB b_ssd for training data
All managed via Terragrunt with shared provider/backend.
Gitignore exception added for infra/*/secrets/ (TF code, not actual secrets).
