KEY INSIGHTS
================================================================================

1. CRITICAL: pot_o.rs is the heart of the system
   └─ Consensus logic, proof generation/verification
   └─ Must be tested exhaustively (10 tests minimum)

2. STATE MANAGEMENT: tensor_network.rs has hard limits
   └─ 256 vertex capacity must be enforced
   └─ 2048 edge capacity must be enforced
   └─ Capacity tests are CRITICAL

3. MATHEMATICAL CORRECTNESS: entropy.rs has complex math
   └─ Logarithmic calculations (ln, tanh)
   └─ Fixed-point conversions (scale 1e6)
   └─ Precision loss boundaries must be tested

4. DETERMINISM: Multiple modules depend on reproducibility
   └─ challenge.rs must produce same challenge for same input
   └─ neural_path.rs must be deterministic per challenge_hash
   └─ pot_o.rs proof hashes must be reproducible

5. ERROR HANDLING: TribeError used throughout
   └─ All error variants must be tested
   └─ Error propagation across module boundaries
   └─ Error messages must be clear

6. HARDWARE CONSTRAINTS: ESP devices have real limits
