kube-rs Client::try_default() uses rustls for in-cluster TLS but no
CryptoProvider was installed, causing a panic on first pod list call.

- StreamSystemStatus now queries real Prometheus data (was all zeros)
- StreamAlerts returns honest unimplemented (was sending empty events)
- Training epoch shows "N" not "N/0" (max_epochs not in proto)
- GPU power shows "300W" not "300W / 0W" when limit unavailable
- Services cockpit shows error reason when service is DOWN
- System status polling detects staleness after 3 consecutive failures
- Training cockpit header shows active K8s job count

config_service.proto (package foxhunt.config, 4 RPCs) was a subset of
config.proto (package config, 12 RPCs). Migrated api_gateway to implement
ConfigService from config.proto directly. Removed dead config_service()
method from fxt client.

Add kube 3.0 + k8s-openapi 0.27 dependencies and create pods_handler.rs
that queries the Kubernetes API for pod status. Replace the UNIMPLEMENTED
stub in monitoring_handler.rs with a real streaming implementation that
polls pods every N seconds and maps them to PodInfo proto messages.

- Add query_cluster_resources() for real CPU/RAM from Prometheus
- Wire into build_response() replacing hardcoded zeros
- Fix NetworkPolicy: add ports 8080/9100/9400 for KSM/node-exporter/dcgm
- Add CiliumNetworkPolicy for hostNetwork pod scraping
- Add SubscribeClusterPods stub to unblock proto addition from Task 5

Added select_action_inference(&self) — pure greedy forward pass with
no exploration mutations (epsilon, noisy nets, count bonus, step counter
are all skipped). Returns (FactoredAction, f32) where confidence is
softmax probability of the selected action, clamped [0.5, 0.95].
Also added select_action_with_confidence(&mut self) for training path
with the same confidence computation.
Production wrapper now uses read lock (was write lock), enabling
concurrent predictions. Confidence is real softmax probability
instead of hardcoded 0.85.
323 trading_service tests, 15 DQN core tests, 0 clippy.

PPO now reads architecture config (state_dim, num_actions, hidden_dims,
clip_epsilon, entropy_coeff, max_grad_norm) from the _metadata.json
saved alongside the actor checkpoint. Falls back to hardcoded defaults
for legacy checkpoints without metadata.
Also fixes predict() to use self.feature_count instead of hardcoded 54,
matching the DQN pattern.
323 tests, 0 clippy.

DQN: disable all exploration for production (warmup=0, epsilon=0,
noisy_nets=false, count_bonus=false), read feature_count from
checkpoint metadata instead of hardcoding 54, add loaded guard
and NaN check on predict output.
PPO: fix confidence formula — use act_with_log_prob() instead of
act() which returns value_estimate not log_prob, add loaded guard
and NaN check, remove WorkingPPO alias.
Liquid: add loaded flag for is_ready()/predict() guards.
Remove EgoboxOptimizer/EgoboxOptimizerBuilder backward-compat
aliases — replaced with canonical ArgminOptimizer everywhere.
323 trading_service tests, 200 hyperopt tests, 0 clippy warnings.

- Rename enhanced_ml.rs → ml.rs, EnhancedMLServiceImpl → MLService
- Drop legacy "Real" prefix: DQNModel, PPOModel, TFTModel, Mamba2Model, LiquidModel
- Delete dead ml.rs stub (was never wired in mod.rs)
- Move model tests into their respective modules with proper test helpers
- DQNModel uses clean DQN API with FactoredAction (45 actions), checkpoint-driven config
- 312 tests passing, 0 clippy warnings

Replace 3 stub RPCs with real implementations:
- get_system_status: fan-out gRPC health checks to all backends, reports SystemStatus
- get_health_check: fan-out checks with response time measurement, returns HealthCheck entries
- get_metrics: queries Prometheus for requested metric names
MonitoringServiceHandler now accepts backend URLs via with_backends() builder.

- Read new env vars: BROKER_GATEWAY_SERVICE_URL, DATA_ACQUISITION_SERVICE_URL,
ML_SERVICE_URL, TRADING_AGENT_SERVICE_URL
- Create lazy channels: trading channel shared by trading/risk/config proxies,
separate channels for ML, broker, data_acq, trading_agent
- Register 7 new services on router with auth interceptor
- Update reflection service with all 6 new proto descriptors
- Add broker/data_acq/trading_agent to health check backend list

fxt 2.0 overhaul: consolidated proto/, absorbed monitoring into API Gateway,
new 15-command CLI with gRPC, MCP server mode, TUI cockpit framework.
159 files changed, net -11,835 lines.
Wire LR scheduler to actually update the Adam optimizer (was logged but
never applied). Add update_learning_rate to DQN, RegimeConditionalDQN,
and DQNAgentType so decay_factor propagates through all agent variants.
Fix train/eval parity: CLI defaults 51→54 features, 3→45 actions;
DQN eval always uses 3-layer hidden_dims; PPO eval uses 5-layer value
network matching trainer. enhanced_ml.rs hardcoded config updated from
state_dim=16/num_actions=3 to 54/45.
Fix Candle F32/BF16 traps: replace `Tensor * 0.5` (f64 literal) with
broadcast_mul(Tensor::full(0.5_f32)) in quantile_regression.rs (2x),
dqn.rs Huber loss, and IQN gamma multiplication. Prevents panics on
Ampere+ BF16 GPUs.
Add urgency_weight() multiplier to training cost model in reward.rs
and portfolio_tracker.rs — urgency dimension (Patient/Normal/Aggressive)
now affects learned value function, matching evaluate_baseline.rs.
Fix equity tracking: additive (equity += ret) → multiplicative
(equity *= 1.0 + ret) in compute_metrics. Fix total return calc.
Fix PER beta annealing: epochs*70 → epochs*1000 (~1015 actual steps
per epoch for 130k bars / batch 128).
Fix silent target network freeze: mutex lock failure now propagates
error instead of silently skipping weight update.
Make save_checkpoint atomic (write .tmp then rename). Make NormStats
write atomic with error logging instead of silent discard.
Convert EnsembleConfig::new assert! → Result<Self, MLError> with
14 call site updates. Fix hyperopt result serialization to warn
instead of silently dropping to Value::Null.
Fix clippy MSRV mismatch: clippy.toml 1.75 → 1.85 matching Cargo.toml.
2732 tests pass, 0 clippy warnings across workspace.

- .gitlab-ci.yml: remove monitoring_service from compile, copy, and deploy loops
- services/trading_service/src/services/monitoring.rs: update stale comments to
reference api_gateway (not monitoring_service) as training metrics host

Port Prometheus scraping and training metrics RPCs directly into
api_gateway, eliminating the monitoring-service backend proxy.
MonitoringServiceProxy replaced with MonitoringServiceHandler that
queries Prometheus directly for training metrics, GPU stats, and
active job counts.
Changes:
- monitoring_proxy.rs -> monitoring_handler.rs with embedded PrometheusClient
- Remove MonitoringBackendConfig and setup_monitoring_proxy from server.rs
- main.rs reads PROMETHEUS_URL + MONITORING_STREAM_INTERVAL instead of
MONITORING_SERVICE_URL
- Remove monitoring-service from backend health check list
- Monitoring is always available (no graceful degradation needed)
- Fix fxt build.rs compile_protos type mismatch
- All 9 ported unit tests + 0 clippy warnings

Delete per-service proto/ directories. All 7 services now compile
from the single canonical proto/ at workspace root.
- trading_service: 5 protos + ml_training client -> ../../proto/
- ml_training_service: ml_training server + fxt_trading client -> ../../proto/
- broker_gateway_service: broker_gateway -> ../../proto/
- trading_agent_service: trading_agent + ml client -> ../../proto/
- data_acquisition_service: data_acquisition -> ../../proto/
- api_gateway: 8 proto compilations -> ../../proto/
- monitoring_service: keeps local proto (3 training RPCs only, deleted in Task 5)
Added proto/fxt_trading.proto (fat-client proto, package foxhunt.tli)
separate from proto/trading.proto (backend, package trading) since the
API gateway needs both for protocol translation.
Added unimplemented stubs for merged monitoring.proto RPCs:
- trading_service: 3 training RPCs (served by monitoring_service)
- api_gateway monitoring_proxy: 13 system health RPCs (Task 4)

Integrate all PPO improvement modules into the core training paths:
- Symlog value predictions in compute_value_loss (MLP + LSTM)
- Adaptive entropy auto-tuning replaces fixed entropy_coeff
- Percentile P5/P95 advantage scaling for heavy-tailed returns
- DAPO clip_epsilon_high wired in all 7 PPOConfig construction sites
- Shape mismatch fix in adaptive_entropy (unsqueeze scalar)

- Implement epoch history ring buffer (50 epochs per session)
- Wire GetEpochHistory RPC with real data
- Add test for financial metric mapping

Add 11 financial fields (sharpe, sortino, win_rate, max_drawdown,
profit_factor, total_return, avg_return, total_trades, action
distribution) to TrainingSession (fields 36-46), a new
GetEpochHistory RPC with request/response messages, and wire the
Prometheus metric mapping in the monitoring service with a
stub RPC handler for task 7.

- 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.

Swap the stale trading_service monitoring proto (10 RPCs, never
implemented) for the real monitoring_service proto (2 RPCs:
GetLiveTrainingMetrics, StreamTrainingMetrics). Add a dedicated
MonitoringServiceProxy that forwards directly to monitoring-service
on port 50057, so `fxt watch` works end-to-end through the gateway.
- build.rs: compile monitoring_service/proto/monitoring.proto with server+client
- MonitoringServiceProxy: new zero-copy proxy (unary + streaming)
- TradingServiceProxy: remove monitoring_client, stub 6 stale methods
- main.rs: MONITORING_SERVICE_URL env, optional proxy with graceful degradation
- Network policies: api-gateway↔monitoring-service egress/ingress on 50057

- ml_training_service: handlers delegate to promotion_manager
- api_gateway: proxy pass-through for both new RPCs

CI training jobs run as GitLab runner pods, not K8s Jobs, so the

Replace the liquidity heuristic in score_symbols with a real
GetEnsembleVote gRPC call to trading-service. Each symbol gets a
