Every clinical-decision-support tool claims accuracy. Few publish their eval portfolio, calibration error, threshold-sensitivity analysis, or model-disagreement rate. Verum runs every change through a 30-case fixture suite and surfaces the numbers below — moveable, inspectable, and per-case visible.
Thirty cases.
28 pass, 2 fail.
Each tile is a synthetic prior-auth case with a hand-curated expected verdict. Green = engine matched expected. Red = mismatch (a true regression you'd want to investigate). Click any tile for the case detail.
Move the threshold.
Watch the portfolio shift.
The conservative-therapy threshold is ≥ 6 weeks by current Medicare LCD. Drag the slider to see how raising or lowering it would shift the 30-case portfolio between approve, pend, and deny outcomes — instantly, in pure code, using the same deterministic gate as the production engine.
When models disagree,
the gate decides.
Two LLM providers, same case, same prompt. They sometimes disagree on edge cases. The deterministic gate evaluates both extractions against the same encoded rules and produces one verdict — even when the upstream extractions vary. This is the core robustness claim: probabilistic intake, deterministic verdict.
“Conservative therapy below the 6-week threshold; recommend additional documentation.”
“Borderline conservative-therapy duration. Weight ODI ≥ 30 favorably; pend for additional records.”
What's encoded.
What's not.
Two ontology cells (lumbar Medicare 2026, cervical Medicare 2026) are flagship REAL — encoded verbatim from CMS LCD L34220 and Aetna CPB 0236, cross-validated against Carelon Imaging of the Spine. The other ten cells are synthetic- representative, flagged in their sourceDocument field. No hidden mocks, no overstated coverage.
