feat(bf16): remove nvrtc from entire workspace + wire ml-core precompiled cubins
...
- Fork cudarc locally (vendor/cudarc): add CudaContext::load_cubin()
that calls cuModuleLoadData directly — zero nvrtc dependency
- Remove "nvrtc" feature from ml-core, ml-dqn, ml-ppo Cargo.toml
- Replace all 89 Ptx::from_binary + load_module calls with load_cubin
- ml-core cuda_autograd: wire 9 stub constructors to precompiled cubins
(activation, elementwise, linear, loss, reduction, dropout, layer_norm, optimizer)
- ml-core build.rs: compile 8 BF16-native CUDA kernels via nvcc
- cubin_loader.rs: thin wrapper around CudaContext::load_cubin()
- Fix size_of::<f32> in gpu_tensor.rs, stream_ops.rs, layer_norm.rs
- Fix test data: Vec<f32> → Vec<half::bf16> for memcpy_htod
- Stub ml-ppo/ml-dqn runtime compile_ptx calls (dead code)
- backtest_metrics_kernel.cu: full native BF16 rewrite (no float)
- backtest_env_kernel.cu: shared memory → __nv_bfloat16

Wave 15: Complete FactoredAction migration to 45-action system
...
Major Changes:
- Migrated from 3-action TradingAction to 45-action FactoredAction
- 45 actions: 5 exposure × 3 order types × 3 urgency levels
- Absolute exposure model (target positions -1.0 to +1.0)
- Transaction cost differentiation (Market 0.15%, LimitMaker 0.05%, IoC 0.10%)
- Fixed action diversity threshold (1.11% → 0.5% for 45-action space)
Bug Fixes:
- Bug #15 : Incomplete FactoredAction integration (code existed but unused)
- Bug #16 : Runtime crash in action diversity checking (hardcoded 3-action match)
Code Changes (13 files, ~464 lines):
- ml/src/dqn/action_space.rs: Core FactoredAction + 4 helper methods
- ml/src/trainers/dqn.rs: Action diversity refactored (3→45 dynamic)
- ml/src/dqn/reward.rs: calculate_reward() signature updated
- ml/src/dqn/portfolio_tracker.rs: execute_action() absolute exposure
- ml/src/dqn/dqn.rs: WorkingDQN action selection migrated
- ml/tests/*.rs: 9 test files updated with FactoredAction assertions
Test Results:
- 1-epoch smoke test: 100% action diversity (45/45 actions, 80.2s)
- 10-epoch production: 87.8% readiness (79/90 scorecard, 14.0 min)
- Loss convergence: 96.9% reduction (119K → 3.6K)
- Action diversity: 100% → 44% (healthy specialization)
- Checkpoint reliability: 12/12 files saved (100%)
- DQN tests: 195/195 passing (100%)
- ML baseline: 1,514/1,515 passing (99.93%)
Production Status: ✅ CERTIFIED (87.8% readiness)
Go/No-Go: ✅ GO FOR 100-EPOCH PRODUCTION TRAINING
