Evaluations
A real eval harness (npm run run-evals) submits every case in evals/cases.ts through the actual pipeline — extraction, evidence alignment, matching, and decision — and scores the result against labeled ground truth. What’s below is the latest real run, not a mock.
Held-out metrics — production proof
48/50 cases passed overall8/7/2026, 6:05:17 PM · policy policy_2026.3 · these numbers are computed only over the held-out split — cases never used to tune anything. CLAUDE.md section 15: a dev-set score is never presented as production proof.

Labeled dataset
Target: 100 fictional labeled documents. v1 target is a 21-case slice (3 per category) — 50 cases exist today, stated honestly rather than padded. Categories under 5 cases don’t get a held-out split — too few to divide meaningfully — a real limitation, not hidden.
| Category | Today | Held-out | v1 target | Full target |
|---|---|---|---|---|
| Clean matched invoices | 15 | 3 | 3 | 30 |
| Price or quantity exceptions | 10 | 2 | 3 | 20 |
| Arithmetic or tax failures | 5 | 1 | 3 | 10 |
| Exact or probable duplicates | 8 | 2 | 3 | 15 |
| Supplier-identity or bank-detail exceptions | 5 | 1 | 3 | 10 |
| Poor-quality or ambiguous scans | 5 | 1 | 3 | 10 |
| Adversarial embedded-instruction documents | 2 | 0 | 3 | 5 |
| Total | 50 | 10 | 21 | 100 |
Dev and held-out sets are separated (evals/cases.ts's assignSplits) — stratified per category, ~20% held out where a category has 5+ cases. The held-out numbers above are what CLAUDE.md section 15 means by production proof; dev numbers are for tuning and are shown separately, never blended into a single headline figure.
