fxt now compiles from the same service protos as all backend services.
Deleted 8 fat-client protos (3,286 lines) from bin/fxt/proto/.
Updated include_proto! macros to use new package names (trading, ml,
config instead of foxhunt.tli, foxhunt.ml, foxhunt.config).
Added risk, data_acquisition, and config_service proto modules.
Fixed duplicate include_proto in agent.rs to use crate::proto.
Existing command implementations will be rewritten to use new proto
types in Task 6.

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)

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.

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
36 files, +293/-72 lines. 2640 tests pass, 0 failures, 0 clippy warnings.

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
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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,
causing InvalidSignature errors against the API gateway. Now reads
jwt_secret from ~/.foxhunt/config.toml with fallback chain:
env var > config file > dev secret.
Also updates default api_gateway_url to https://api.fxhnt.ai.

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
