e4870b17b9 fix: tune log levels across workspace — demote noisy warn to debug/trace
Reduce log noise for non-critical operational paths: connection retries,
expected fallbacks, graceful degradation, and optional feature absence.
Keeps warn/error for genuine failures requiring attention.

- Replace Vec::remove(0) with VecDeque ring buffers (O(1) vs O(n))
- Add Arc<AtomicBool> connected_sent for first-connected detection across 12 streams
- Add MAX_RECONNECT_ATTEMPTS (10) uniformly to all stream spawners
- Change kill switch/circuit breaker fields to Option types with N/A display
- Wire data_cache to real download status stream, remove dead cluster_events
- Remove ServiceData::new() hardcoded stubs, add honest placeholders
- Fix nanos_to_hms zero/negative guard, total_records semantic fix
- Fix RwLock held across yield in broker_gateway stream_account_state
- Add break after yield Err in broker/trading stream generators
- Fix connected_at advancing per tick in stream_session_status

d04b6c7023 fix(fxt,services): remove mock fallbacks and add gRPC health checks
- trade_ml.rs: Replace 3 mock data fallbacks (submit, predictions,
  performance) with proper error propagation. Commands now fail
  honestly when the API Gateway is unreachable instead of silently
  returning fake data. Mark 3 integration tests as #[ignore].

- monitoring_service: Add tonic-health with set_serving for
  MonitoringServiceServer. Enables grpc_health_probe readiness checks.

- ml_training_service: Add tonic-health with set_serving for
  MlTrainingServiceServer. Wired into both TLS and non-TLS paths.

- data_acquisition_service: Add tonic-health with set_serving for
  DataAcquisitionServiceServer.

- ml/cuda_streams: Fix pre-existing unused variable clippy warning.

All 8 services now have standard gRPC health checking enabled.

0ac8aeee52 refactor(common): make init_observability sync with optional OTLP endpoint
Remove unnecessary async from init_observability -- body was fully sync.
Change otlp_endpoint from &str to Option<&str> -- when None, OTLP layer
is skipped (fmt-only mode). Update all 8 service callers.

74a572a5c4 feat(infra): enable MinIO TLS with self-signed CA for in-cluster HTTPS
Switch all MinIO communication from HTTP to HTTPS across the entire stack:
- MinIO deployment: mount TLS secret, tcpSocket probes, HTTPS init-buckets
- 11 service YAMLs: HTTPS rclone endpoint + CA cert volume mount
- Training job template + train.sh: HTTPS for fetch-binaries and uploader
- CI pipeline (.gitlab-ci.yml): all 7 rclone exports use HTTPS + CA cert
- GitLab runner values: minio-ca-cert ConfigMap volume for CI pods
- Rust: CA cert loading via MINIO_CA_CERT_PATH in training_uploader,
  storage backend, data_acquisition uploader, and k8s_dispatcher
- Cert generation script (infra/scripts/generate-minio-tls.sh)

Fixes training uploader S3 upload failures caused by with_allow_http(false)
connecting to an HTTP endpoint.

86f7f1fa76 fix: comprehensive audit — real brokers, deployment fixes, production safety
Codebase audit identified 23 findings across 4 dimensions (production safety,
code health, deployment readiness, test quality). This commit fixes all of them.

Broker execution layer (was entirely stubbed):
- Real IBKR TWS client via ibapi crate (950+ lines, feature-gated)
- ICMarkets ctrader-openapi now always-on (removed feature flag)
- Real broker routing with health monitoring and exponential backoff reconnect
- Validated against live IB Gateway Docker (6/6 connectivity tests pass)

Deployment blockers:
- Fixed 6 broken Dockerfiles (removed COPY foxhunt-deploy)
- Created foxhunt K8s namespace, secret templates, migration job
- Added liveness probes to all 7 K8s services
- IB Gateway manifest (ghcr.io/gnzsnz/ib-gateway:stable)
- IBKR credentials in Scaleway Secret Manager via Terragrunt
- Fixed port collisions and mismatches across services

Production safety (9 critical + 6 high/medium fixes):
- Asset-class-specific VaR volatility (not flat 2%)
- Real parametric VaR with z-score 95th percentile
- Kyle's lambda regression (100-bar rolling window)
- Per-feature running statistics from historical data
- VWAP-based slippage reference, regime duration tracking
- Real Databento JSON parsing for OHLCV/Trade/Quote

Code health:
- Removed #![allow(dead_code)] from ml, data, config
- Fixed log:: → tracing:: in 4 production files
- Removed dead workspace deps (ratatui, crossterm)

Verified: cargo check --workspace (0 errors), trading_engine 330 tests pass.
