DQN and PPO trainers now resolve hidden_dim_base from GPU VRAM when no
explicit override is given, so L4/L40S/H100 GPUs use proportionally
larger networks instead of being stuck at RTX 3050 Ti defaults (256).
- Add resolve_hidden_dim_base() tiered lookup (256/512/768/1024 by VRAM)
- Add network_param_count() for accurate model size estimation
- DQN: pre-compute hidden dims, use real param count for batch sizing
- PPO: add hidden_dim_base field, VRAM resolution in PpoTrainer::new()
- PPO hyperopt: raise hidden_dim_base ceiling from 2048 to 4096
- TFT hyperopt: expand hidden_sizes from [128,256,512] to 5 tiers
- Update stale estimates (DQN 50K→200K, PPO 100K→400K params)
- Fix pre-existing clippy lints in prefetch.rs and ppo.rs

11-task step-by-step plan: create platform pool, move monitoring
(stateless), migrate databases (PVC migration with backups), scale
services pool to 1 node. Includes verification and rollback procedures.

Isolate platform infra (postgres, redis, minio, monitoring) from foxhunt
app services on separate DEV1-L nodes. Same EUR 61/mo total cost, better
blast radius containment and burst headroom for trading services.

Infrastructure Cockpit:
- GPU gauges → side-by-side timeseries (GPU Utilization + GPU VRAM with total line)
- Added Memory by Service timeseries next to existing CPU by Service
- Cluster resource gauges shrunk to h=4 for tighter layout
Training Cockpit:
- GPU Utilization/Memory gauges → side-by-side timeseries matching infra cockpit
- GPU Temperature/Power widened from w=6 to w=12 in paired row

6 stat panels (Ensemble Agreement, Prediction Confidence, Model Accuracy,
Ensemble Sharpe, Realized PnL, Unrealized PnL) showed red when ML metrics
don't exist yet. Added special null mapping → "Inactive" in dark-blue.
Panels will still show red/yellow/green when the trading system is active
and emitting metrics.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The "Active CI Jobs" stat panel used sum(gitlab_ci_active_jobs_sum) which
is a histogram accumulator that only grows (was showing 982 red). Changed
to sum(increase(pipeline_processing_events_total[1h])) which shows actual
pipeline activity in the last hour. Threshold changed to blue=idle,
green=active.
Also fixed Grafana provisioning:
- Removed overlapping named providers (cockpits/operations/infrastructure/cicd)
that duplicated sidecarProvider, causing UID conflicts and write lockout
- Enabled foldersFromFilesStructure on sidecarProvider
- Unlabeled grafana-dashboards-foxhunt ConfigMap (duplicate of cockpits+operations)

- Change training job tags from kapsule to kapsule-rl so they are
picked up exclusively by the RL runner (GPU-dedicated), not the
general runner (CPU compile pool).
- Add OTEL_EXPORTER_OTLP_ENDPOINT to both .train-rl-base and
.train-validate-base so training binaries export OTLP traces
to Tempo.
- Update allow-monitoring-scrape NetworkPolicy to include
foxhunt-ci pods so CI training pods can reach Tempo:4317.

CI build pods have label app.kubernetes.io/part-of=foxhunt-ci,
not foxhunt. Add foxhunt-ci to the MinIO NetworkPolicy ingress
values so compile/upload jobs can reach MinIO S3 endpoint.

Adds 12 stat panels in a new row between Service Status and Resources:
- Infrastructure: postgres, redis, minio, questdb (UP/DOWN)
- GitLab: webservice status + link to gitlab-services dashboard
- Network: tailscale proxy
- Monitoring: grafana, loki, tempo, kube-state-metrics (UP/DOWN)
- Counts: CI runners (active), collectors (promtail + node-exporter)
Uses w=4 panels (6 per row) for better readability on small screens.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New row shows GitLab, CI Runners, Monitoring, Collectors, Tailscale,
and Platform Total stat panels, plus a pod status table, CPU/memory
timeseries, and container restart chart for all non-foxhunt pods.
Also fix minio-init-buckets job: remove part-of:foxhunt label (triggers
default-deny egress block) and rely on minio NetworkPolicy ingress
allowlist for minio-init pods instead.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The minio-init-buckets job pod has label app.kubernetes.io/name: minio-init
which doesn't match part-of: foxhunt (adding part-of would trigger
default-deny egress). Add explicit ingress allowlist entry for minio-init
pods on the minio NetworkPolicy.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
All per-service NetworkPolicies used bare 'app: postgres/redis/minio'
selectors but infrastructure pods use 'app.kubernetes.io/name'. This
blocked all egress to databases, causing initContainer hangs and
service connectivity failures.

Pod-level runAsNonRoot:true conflicts with initContainer runAsUser:0.
Kubernetes rejects the container. Add explicit override so the
initContainer can still run as root to fetch binaries from S3.

GitLab webservice/sidekiq share the foxhunt namespace but don't have
part-of=foxhunt label. Add release=gitlab selector to postgres and
redis NetworkPolicies so GitLab can reach its database.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Caught during pre-apply review:
- Scope default-deny/allow-dns/allow-monitoring to pods with
app.kubernetes.io/part-of=foxhunt (was podSelector:{} which would
block gitlab, grafana, loki sharing the namespace)
- Fix infrastructure.yaml: use app.kubernetes.io/name instead of
bare app label for postgres/redis/minio/questdb podSelectors
- Add app.kubernetes.io/part-of=foxhunt to all pod templates so
default-deny and infrastructure ingress rules match correctly

Previous fix tried appending to /etc/ssl/certs/ca-certificates.crt
which fails on non-root containers (Permission denied). Instead,
copy system CAs to /tmp/ca-bundle.crt, append MinIO CA, and set
SSL_CERT_FILE for Go's crypto/tls.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
RCLONE_CA_CERT env var does not apply to rclone's S3 backend — Go's
crypto/tls reads from the system CA bundle. Append the MinIO CA cert
to /etc/ssl/certs/ca-certificates.crt before rclone commands. Fixes
compile-services, compile-training, web-dashboard, write-manifest,
and both training base templates.

db-credentials, jwt-secret, redis-credentials, s3-credentials.
Each service only references the secrets it needs.
Values are REPLACE_IN_DEPLOY markers — real values
injected by scripts/deploy-secrets.sh.
Also updated references in postgres.yaml, migrate.yaml,
and postgres-init.yaml to use db-credentials.

Least-privilege ingress/egress for all 8 services + IB gateway +
infrastructure pods (postgres, redis, minio, questdb). Each policy
restricts which pods can communicate on which ports, limiting lateral
movement in the cluster.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Establishes zero-trust network baseline for the foxhunt namespace:
- default-deny-all: blocks all ingress/egress unless explicitly allowed
- allow-dns: permits CoreDNS (kube-system) egress on UDP/TCP 53
- allow-monitoring-scrape: allows Prometheus ingress on metrics ports
(9091-9098) and Tempo OTLP gRPC egress on 4317
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Minimal hardening plan for production deployment: NetworkPolicy
(default-deny + explicit allow), SecurityContext on all pods,
secret scoping (split monolithic foxhunt-secrets), and Trivy
image scanning in CI pipeline.
