Methodology
- Precision is computed weekly over the last 500 checks with confirmed outcomes.
- A verdict is correct when the engine's determination matches the actual customs clearance outcome.
- False positives: engine said "mandatory" but item cleared without BIS registration.
- False negatives: engine said "not required" but item was held for BIS compliance.
- Adversarial test fixtures (b18_adversarial source) are excluded from production scores.
- The "public claim" requires 4 consecutive full-window (≥ 500 outcomes) weeks ≥ 99%.
