Integrate three standalone PPO modules into the hyperopt training loop:
- PPORewardShaper: hold penalty + rolling Sharpe + diversity bonus per step
- CompositeReward: risk-adjusted reward (downside dev + differential return)
- TrajectoryReplayBuffer: ExO-PPO M=4 rollouts with IS-weighted replay
Also fixes GAE hardcoded gamma=0.99/lambda=0.95 — now uses hyperopt params.
2726 tests pass, 0 clippy errors.

Merge monitoring_service training metrics into trading_service system health
monitoring.proto. All 11 proto files now in one canonical location.
Merged monitoring.proto has 13 RPCs (10 system + 3 training) with all
message types from both source protos preserved. Added cpu_percent,
memory_used_mb, memory_total_mb fields to GetLiveTrainingMetricsResponse.

Change --optimizer default from "pso" to "tpe" since TPE has better
sample efficiency in 25D spaces. Fix clippy let_underscore_must_use
on CUDA sync tensor readback.

Fix 20 exotic parameters to validated defaults, keeping only the 25
that genuinely affect trading performance. This makes both PSO and
TPE dramatically more effective at exploring the parameter space.

Replace DType::F32 with training_dtype(&device) for action one-hot
encoding and state embedding conversion. On BF16 devices, model
weights are BF16 but inputs were F32, causing dtype mismatch errors.

Force CUDA synchronization between trials by creating a tiny tensor and
reading it back (forces cudaDeviceSynchronize). This ensures GPU memory

Add a standalone TPE optimizer for Bayesian hyperparameter optimization that
replaces PSO by modeling good/bad trial distributions with per-dimension
kernel density estimates. Includes Latin Hypercube Sampling for initial
exploration, Silverman bandwidth selection, log-sum-exp numerical stability,
and JSON-based trial persistence. 15 tests covering splits, bounds, KDE
density, convergence on 1D/2D objectives, and history serialization.

sample_noise(), sigma init, disable_noise(), and epsilon buffers all
used hardcoded DType::F32. When weights are BF16 on Ampere+ CUDA,
this caused dtype mismatch in mul/add operations during forward pass.
Fix: use training_dtype(device) for all noise-related tensors.

A+B approach: smooth penalties + position limits + CUDA cleanup +

After converting all VarBuilder sites from F32 to training_dtype (BF16 on
Ampere+ GPUs), input tensors from callers remain F32, causing dtype
mismatches in matmul/add/mul operations. This commit adds systematic
boundary casts across all 10 model architectures:
- Input boundary: ensure_training_dtype() at each model forward() entry
- Output boundary: to_dtype(F32) at each model forward() exit
- Internal intermediates: hidden state init, gradient extraction,
positional encodings, causal masks, SSM state matrices, B-spline
basis values all cast to match computation dtype
- Ensemble adapters: ensure_training_dtype after Tensor::from_vec

Replace DType::F32 with training_dtype(&device) in VarBuilder::from_varmap
calls across TFT, Mamba2, Liquid/CfC, KAN, xLSTM, Diffusion, TGGN, TLOB.
61 sites changed across 25 files (production constructors + test helpers).

Replace DType::F32 with training_dtype(&device) in all VarBuilder::from_varmap
calls across 16 DQN files (~55 call sites). This enables automatic BF16 weight
initialization on Ampere+ GPUs while keeping F32 on CPU and older hardware.

- gpu_replay_buffer: allocate states/next_states with training_dtype(),
cast incoming batches at ingestion boundary
- gpu_weights: cast BF16 model weights to F32 before extraction for
CUDA f32 kernels in both extract_one() and sync_one()
- mod.rs: cast DqnGpuData, GpuBufferPool, PpoGpuData uploads to
training_dtype(); cast portfolio tensors to match features dtype;
cast bar_target_values readback to F32

Cast state tensors to BF16 (via training_dtype()) at all DQN network
input sites: compute_loss_internal states/next_states, select_actions_batch,
curiosity module state/next_state, validation batch, and Q-value logging
batch. Non-network tensors (actions, rewards, dones, weights) are left
as F32 since they participate in loss math, not forward passes.

Previously scalar_tensor() rejected BF16 and F16 with an error,
blocking BF16 training for Mamba2. Now BF16/F16 scalars are created
as F32 then cast to the target dtype, matching Candle's internal
precision requirements while supporting half-precision training.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add detect_from_gpu_name_auto() which uses cached nvidia-smi GPU
capabilities to auto-detect mixed precision config, and training_dtype()
which returns BF16 for Ampere+ CUDA GPUs and F32 for everything else.
This is the single entry point for "what dtype should weights use?"

Add print_financial_metrics() to the monitor command, displaying
per-model Sharpe ratio (color-coded green/yellow/red), win rate,
max drawdown, profit factor, total return, trade count, and
action distribution (BUY/SELL/HOLD percentages). Only shown when
sessions report non-zero financial data.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add Sharpe/Win% columns to training list table, financial summary lines
(Sharpe, Sortino, Win Rate, Max DD, PF, Return, Avg, Trades) to the
detail overview, action distribution (BUY/SELL/HOLD %) to current metrics,
and four new sparklines (Sharpe, Win Rate, Max DD, Total Return) to the
Metrics sub-tab.

- 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.

Replace per-bar GPU forward passes with chunked batch inference (1024 bars
per chunk). This reduces ~90K individual CUDA kernel launches to ~88 batched
forward passes — ~1000× fewer GPU round-trips.
Changes:
- Add DQN::batch_greedy_actions(&self) for immutable batched forward+argmax
- Add RegimeConditionalDQN::batch_greedy_actions with per-regime-head batching
- Add DQNTrainer::convert_to_state_vec (CPU-only, skips GPU tensor allocation)
- Add PortfolioTracker::set_position_direct for backtest state sync
- Rewrite hyperopt backtest loop: chunked batching with portfolio state
updates between chunks (1024-bar granularity ≈ 17h of 1-min data)
Portfolio features (last 3 of 54 dims) are refreshed between chunks via
set_portfolio_for_backtest(), keeping position/PnL/exposure accurate at
chunk boundaries while batching inference within each chunk.
2640 tests pass, 0 clippy warnings.

Split model overhead into two constants: MODEL_OVERHEAD_MB (pure
model weights for batch-size capping) and TRIAL_VRAM_MB (total
per-trial VRAM for concurrent hyperopt planning). DQN trials
empirically consume ~7 GB each on L40S (model + GPU replay buffer +
experience collector + CUDA allocations + fragmentation), not the
200 MB previously estimated. This caused plan_hyperopt to compute
128 concurrent trials instead of the actual 5, inflating PSO
particles from 20→128 and total trials from 20→384 via .max()
instead of .min(), guaranteeing a 4h timeout kill.
Fix auto-scaling to: (1) match particles to GPU concurrency for
maximum hardware utilization on any node, (2) cap particles at
max_trials to never inflate the trial budget, (3) never auto-inflate
the total trial count.

The GPU experience collection path bypassed monitor.track_action(),
leaving action_counts all zeros and reporting 0/45 diversity on every
epoch. Feed batch.actions into monitor.action_counts after GPU
collection so the metric reflects actual policy behavior.

The fxt client was using a hardcoded dev fallback secret for JWT signing,

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
