4b15108895 feat(ppo): wire reward shaping, composite reward, trajectory replay into hyperopt
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.

ed1ab8ed88 feat: create consolidated proto/ directory at workspace root
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.

ba8fb8eedd feat(ppo): wire symlog, adaptive entropy, percentile scaling into training loop
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)

2726 tests pass, 0 clippy errors.

50b75b8a5f feat(ppo): curiosity port + reward shaping + ExO-PPO replay + composite reward
Phase 6: CuriosityModule wired into PPO hyperopt (14D). Intrinsic reward
from forward dynamics prediction error scales by curiosity_weight param.

Phase 7: PPORewardShaper with hold penalty (discourages flat position),
rolling Sharpe (20-step window), diversity bonus (smooth quadratic
entropy). 8 tests.

Phase 8: ExO-PPO trajectory replay buffer (M=4 FIFO). Importance-weighted
surrogate with exponential attenuation outside clip bounds (alpha=5).
4x sample efficiency over standard PPO. 10 tests.

Phase 9: CompositeReward with annualized return, downside deviation
penalty, and differential return vs SMA baseline. 10 tests.

2ac4525399 feat(ppo): enable DAPO asymmetric clipping by default (clip_epsilon_high=0.28)
Clip range [1-0.2, 1+0.28] = [0.8, 1.28] allows larger policy updates
toward profitable actions while being conservative about penalizing
exploration. ByteDance DAPO 2025 — 50% faster convergence.

235cee5b50 feat(ppo): expand search space 7D→13D + symlog + adaptive entropy + percentile scaling
Phase 1: PPOParams expanded with gae_gamma, gae_lambda, mini_batch_size,
max_grad_norm, max_position_absolute, clip_epsilon_high. All wired into
PPOConfig construction. CUDA cleanup with tensor readback sync.

Phase 2: Symlog value transform (DreamerV3) — sign(x)*ln(|x|+1) for
compressing large financial returns while preserving sign. 13 tests.

Phase 4: Adaptive entropy coefficient (SAC-style) — learnable log(alpha)
auto-tuned via dual gradient descent toward target entropy. 9 tests.

Phase 5: Percentile advantage scaling — EMA-tracked P5/P95 for robust
normalization of heavy-tailed financial returns. 11 tests.

sample_noise(), sigma init, disable_noise(), and epsilon buffers all

864808e056 fix(ml): add ensure_training_dtype boundary casts to all model forward methods
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

25f8d514b1 perf(ml): batched GPU inference for hyperopt backtest evaluation
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.

a7b7796147 fix(ml): correct PSO auto-scaling with empirical VRAM estimates
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.
