Checkpoint	1	7.1%	LOW
TGNN (Graph Networks)	1	7.1%	LOW
Batch Processing	1	7.1%	LOW

1. PPO Module Failures (5 tests)

Root Cause Pattern: Tensor rank mismatches - scalar expected, got 1D/2D tensors

Failing Tests:

1. ppo::continuous_demo::tests::test_continuous_demo

   • Error: "Candle error: unexpected rank, expected: 0, got: 1 ([1])"
   • File: /home/jgrusewski/Work/foxhunt/ml/src/ppo/continuous_demo.rs:226
   • Impact: Demo showcases position sizing but fails on entropy extraction

2. ppo::continuous_policy::tests::test_forward_pass

   • Error: "unexpected rank, expected: 0, got: 2 ([1, 1])"
   • File: /home/jgrusewski/Work/foxhunt/ml/src/ppo/continuous_policy.rs:466
   • Impact: Basic forward pass validation fails on tensor extraction

3. ppo::continuous_policy::tests::test_numerical_stability

   • Error: "unexpected rank, expected: 0, got: 2 ([1, 1])"
   • File: /home/jgrusewski/Work/foxhunt/ml/src/ppo/continuous_policy.rs:641
   • Impact: Numerical stability tests cannot verify extrema handling

4. ppo::continuous_ppo::tests::test_continuous_action_selection
