Measured system behavior
Evaluation results that show where the system works—and where it does not.
Evaluation scorecard
Held-out proof first. Failures kept visible.
No customer invoices are used, and no development-set score is presented as held-out production proof.
Held-out metrics — production proof
7/10 held-out cases passed2026-08-16 12:44 UTC · 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.

Failure analysis
The latest run contains 15 case-level failure(s). They are retained publicly instead of being removed from the dataset. Review the failed check names in the table above; remediation focuses on extraction support and evidence alignment, while deterministic financial controls continue to prevent unsupported invoices from being cleared.
Upload sandbox validation results
A small, separate case set run through the actual bring-your-own-invoice upload path — not the seeded-scenario
intake above — to prove the upload-mode policy variant behaves as designed. Most importantly, that an uploaded
document can never reach ready_for_approval,
even one that would otherwise cleanly match everything. This is validation of a code path, not a statistical
accuracy claim — it is never combined with the held-out or dev numbers above.
No upload-eval run yet — this section populates once the upload sandbox validation harness has run.
Labeled dataset
Target: 100 fictional labeled documents. v1 target is a 21-case slice (3 per category) — 50 cases ran in the latest recorded run, 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 | v1 target | Full target |
|---|---|---|
| Clean matched invoices | 3 | 30 |
| Price or quantity exceptions | 3 | 20 |
| Arithmetic or tax failures | 3 | 10 |
| Exact or probable duplicates | 3 | 15 |
| Supplier-identity or bank-detail exceptions | 3 | 10 |
| Poor-quality or ambiguous scans | 3 | 10 |
| Adversarial embedded-instruction documents | 3 | 5 |
| Total | 21 | 100 |
Dev and held-out sets are separated — 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.

The evaluation methodology is part of the portfolio evidence.
The public scorecard separates held-out and development cases, preserves failures, measures critical false clearances independently, and reports latency and model cost.
