- 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)
- Compute max_drawdown from cumulative PnL samples in A/B testing pipeline
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)

4 tests validating the 51-dim feature extraction pipeline:
- DBN data loading (graceful skip if file absent)
- Synthetic bars: dimension check (51-dim), no NaN/Inf
- Value range bounds (-100 to 100)
- Streaming vs batch consistency (element-wise 1e-10 tolerance)

Remove 520 lines of ndarray-based placeholder code that never performed real
gradient descent. Production training uses Candle-based trainers in ml::trainers/.
Deleted: SimpleNeuralNetwork, TrainingPipeline, NetworkConfig, ActivationType,
TrainingMetrics, NetworkInterface, MockNetwork, and 9 associated tests.
Kept: DeviceCapabilities, TrainingConfig, sub-module re-exports.

Replace load_and_split_data() mock that generated 2000 synthetic samples
with an error-returning stub directing users to ml_training_service.
The binary retains its real infrastructure (TFTTrainer, CLI, checkpoint
storage, progress callbacks) — only the fake data generation is removed.
-120 lines of mock data, +16 lines error stub with documentation.

Extend checkpoint_roundtrip.rs with 4 new tests for sequence-buffered models:
- TFT adapter deterministic inference: verifies same adapter produces
identical direction/confidence on repeated calls with stable buffer
- TFT quantile metadata: confirms quantiles are absent during buffering
phase and present (with correct count) after buffer fills
- Mamba2 adapter deterministic inference: same pattern as TFT, verifies
direction/confidence stability and correct model name ("MAMBA-2")
- Mamba2 CheckpointManager roundtrip: saves/loads via Checkpointable
trait on Mamba2SSM, verifies metadata tags and hyperparameters
All 10 tests (6 existing DQN/PPO + 4 new TFT/Mamba2) pass consistently.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add 6 integration tests that verify model weights survive a full
checkpoint cycle (serialize -> save to disk -> load -> predict):
- DQN raw Q-network weight roundtrip via safetensors
- DQN adapter roundtrip via DqnInferenceAdapter::from_checkpoint
- DQN CheckpointManager + Checkpointable trait flow
- PPO actor/critic checkpoint roundtrip with exact output comparison
- PPO inference after checkpoint load (probability validation)
- PPO adapter deterministic prediction verification
Fix a bug in DQN::load_from_safetensors where inserting new Var
objects into the VarMap HashMap left the Linear layers pointing at
stale data. The fix uses VarMap::load() which correctly updates
existing Vars in-place via Var::set(), preserving the shared
Arc<RwLock<Storage>> between VarMap entries and Linear layer tensors.

Phase 1: ML pipeline verification (checkpoint roundtrip, feature extraction)
Phase 2: Service production logic (hardcoded values, stub responses)
Phases 3-5: Backtesting, ML crate TODOs, infrastructure/security/cleanup

Covers all TODO/FIXME items across workspace, checkpoint roundtrip
tests, feature extraction pipeline tests, and infrastructure cleanup.

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

- DQN: adapter creation, deterministic inference, varied inputs
- PPO: adapter creation, deterministic inference, short input padding
- TFT: sequence buffering, valid prediction after warmup
- Mamba2: sequence buffering, valid prediction, deterministic SSM
- Ensemble: all 4 models -> EnsembleCoordinator -> trading decision
- Smoke: full pipeline with 10 sequential predictions, stability check
This establishes the production baseline proving the ML pipeline works
end-to-end with all 4 models contributing to ensemble decisions.
