Add 25 unit tests for the RiskServiceImpl pure functions:
- Parametric VaR fallback formula (notional * 0.02)
- Equal contribution percentage for N symbols (including empty)
- Drawdown computation (empty, positive PnL, negative, mixed)
- Returns from executions (empty, single, sorted, zero-price filtering)
- Volatility (empty, single, constant, known series)
- Sharpe ratio (insufficient data, zero vol, positive returns)
- Sortino ratio (insufficient data, no downside, mixed)
- VaR square-root-of-time scaling (1d→5d→30d)
- Concentration risk level thresholds
- Risk constants validation

Add optional correlation matrix parameter to mean-variance optimization.
When provided, builds full covariance matrix (Sigma[i][j] = corr[i][j] *
vol_i * vol_j) instead of diagonal-only. Existing API unchanged — callers
pass None by default. New allocate_with_correlations() public method for
correlated optimization. Five new tests: identity-matches-diagonal,
correlated-differs-from-diagonal, invalid dimensions, non-square matrix,
and non-MeanVariance delegation.

Add defensive checks to FeaturePreprocessor::normalize():
- Return 0.0 with warning log for NaN/Inf input values
- Clamp z-score output to [-10, 10] to prevent extreme values
- Add 4 unit tests covering NaN, Inf, -Inf, and extreme value clamping

Move position fetching before VaR calculation in both get_va_r and
get_risk_metrics so the portfolio notional is computed from real
position data (sum of |quantity * avg_price|) instead of the fake
confidence_level * 1_000_000.0 placeholder. Falls back to 100_000.0
when the portfolio is empty.

Replaces hardcoded zeros in AssetAllocation with real position data
queried from agent_orders. Adds fetch_current_positions() helper that
derives net quantity per symbol (buy - sell) and reuses it in both
allocate_portfolio and rebalance_portfolio to eliminate SQL duplication.

Closes the integration gap between Liquid CfC and DQN/PPO by adding:
- LiquidTrainer with gRPC progress callbacks, early stopping, and
checkpoint management (ml/src/trainers/liquid.rs)
- LiquidModel wrapper in enhanced_ml.rs for hot-loading from safetensors
- Ensemble weight rebalance: DQN 0.25, PPO 0.25, TFT 0.20, Mamba2 0.15,
Liquid-CfC 0.15
Verified: 81 liquid unit tests + 3 integration tests + 211 trading_service
tests pass, 0 compile errors across workspace.

- Add load_from_safetensors() to DQNAgent for weight loading via VarMap
- Update RealDQNModel::from_checkpoint to try safetensors first, fall back to JSON
- Replace std::mem::forget(prediction_shutdown_tx) with proper Vec-based storage
that sends shutdown signal and drops senders during graceful shutdown
- Wire order_manager.get_open_orders() into emergency_stop response so callers
see which orders were active when the kill switch engaged

Replace hardcoded position_size: 1000.0 with actual position quantities
from fetch_positions(). Compute contribution_pct as marginal VaR ratio
(symbol_var / portfolio_var * 100) instead of naive equal-weight split.

Replace 7 hardcoded 0.0 values with real calculations:
- target_quantity from last close price
- portfolio_volatility from log return stddev * sqrt(252)
- portfolio_sharpe from weighted returns / portfolio vol
- var_95 parametric VaR
- max_drawdown_estimate from vol approximation
- rebalance_delta as target - current (0 until positions available)
- per-asset volatility from price bars (was hardcoded 0.15)

Tasks 8-14 production hardening batch:
- Populate Order/Position/Execution proto messages from JSON payload in event
stream converters instead of returning None (Task 9)

instead of hardcoded 0.0 (Task 11)
- Document feature pipeline integration blockers with detailed roadmap
comments in state.rs and trading.rs (Task 8)
- Document realized PnL gap: TradingPosition lacks the field, repository
has async method incompatible with Iterator::map (Task 10)
- Document ML order quantity gap in api_gateway proxy: MlOrderResponse
proto lacks quantity field (Task 12)
- Document per-symbol weight tracking roadmap in ensemble_coordinator (Task 13)
- Document OHLCV bar pipeline upgrade roadmap in state.rs (Task 14)

Consolidate 4 separate ModelType enum definitions (ml 15 variants,
model_loader 7, campaign 2, job_spawner 4) into a single canonical
definition in common/src/model_types.rs with the union of all variants
and all methods (file_extension, as_str, to_db_string, weight, from_str,
Display).
- ml/src/lib.rs: replace 15-variant enum with re-export
- model_loader/src/lib.rs: replace 7-variant enum with re-export,
update PascalCase names (Dqn->DQN, Tft->TFT, etc)
- ml/hyperopt/campaign.rs: replace 2-variant enum with re-export
- services/ml_training_service/job_spawner.rs: replace 4-variant enum
with re-export, MAMBA2->MAMBA
- Remove orphan impl ToString in ml/observability/metrics.rs (Display
now provided by canonical type)
- Update backtesting_service and model_loader tests for new names

Move identical TLS type definitions from 4 service crates into
common/src/tls.rs, eliminating ~435 lines of duplicated code.
Each service retains its own TlsConfig struct and validation logic
(async vs sync, delegated vs monolithic) while sharing the type
definitions. Services re-export the types for backward compatibility.

Removed 3 duplicate ModelType enums (model_loader, hyperopt campaign,
job_spawner). Canonical definition in ml/src/lib.rs with 15 variants.
model_loader and job_spawner now re-export from ml. Added as_str(),
s3_prefix(), Display, to_db_string(), and weight() to canonical enum.
Replaced conflicting ToString impl with Display. Fixed variant name
mismatches (Dqn->DQN, Mamba2->MAMBA, Liquid->LNN, TlobTransformer->TLOB).

Removed duplicate DQNConfig from agent.rs (13 fields, pre-Rainbow with
f64 gamma/epsilon) and adaptive-strategy stub (unit struct). Canonical
definition in dqn/dqn.rs now has 51 fields covering full Rainbow DQN
plus agent-level trading parameters (minimum_profit_factor, weight_decay).
Key changes:
- agent.rs imports DQNConfig from dqn.rs instead of defining its own
- Fixed f32/f64 type mismatches (epsilon_start/end/decay cast to f64
where QNetworkConfig expects f64)
- Renamed replay_buffer_size -> replay_buffer_capacity across all callers
- Updated 13 files across ml, adaptive-strategy, and trading_service
- All 2009 ml tests pass, 0 clippy warnings in modified files

- broker_gateway: use 100ms circuit breaker timeout in tests (was 60s)

Add optional cTrader broker integration behind `icmarkets` feature flag.
When CTRADER_ENABLED=true with credentials, orders are routed to cTrader
after DB persistence. Handlers for account state, positions, execution
streaming, and cancellation all proxy through the live broker when
connected.

Remove 45+ AGENT_*, WAVE_*, and completion report files that were

changes already landed). Content preserved in git history.

Wire Mamba2 model type into the gRPC model loading match in enhanced_ml.rs.

Replace last 2 stub gRPC handlers with real implementations:
- GenerateOrders: loads allocation, generates orders via OrderGenerator with
ML signal context, contract price estimation, and dynamic stop-loss
- SubmitAgentOrders: validates orders, supports dry_run mode, persists to
agent_orders table with full metadata
Trading agent service: 15/15 endpoints now have real implementations.

Replace Status::unimplemented() with real streaming implementations:
- stream_va_r_updates: periodic VaR recalculation with change detection
- stream_risk_alerts: kill switch status + VaR breach monitoring
- stream_system_status: real-time health, CPU/memory/disk metrics
- stream_metrics: trading performance counters (connections, requests, latency)
- stream_alerts: operational alerts for health/CPU/memory/disk anomalies
All use tokio::time::interval with graceful client disconnect handling.

Wire EnsembleCoordinator with 4 candle-backed inference adapters:
- DQN (0.30 weight), PPO (0.30), TFT (0.20), Mamba2 (0.20)

- RebalancePortfolio: compares target vs current positions, generates drift-based actions
- GetAgentPerformance: queries agent_orders for P&L, win rate, Sharpe, max drawdown
- StreamAgentActivity: sends 5-second heartbeat events until client disconnects
Trading agent service: 14/15 endpoints now have real implementations.

Compute real values for 5 previously-zero risk metrics:
- current_drawdown: from unrealized PnL vs market value
- volatility: annualized std dev from execution price returns
- sharpe_ratio: excess return / volatility * sqrt(252)
- sortino_ratio: excess return / downside deviation * sqrt(252)
- position_risks: per-position VaR contribution and concentration
Wire get_position_risk() to real positions with filtering.
beta/alpha remain 0.0 (requires benchmark data integration).
