Under the hood / Evals
Evals: what passes, and what doesn't.
A fixed test set runs against the same code as the chat and the fit check before every build. A score that drops fails the build. Failures are listed below, not hidden.

Scores
The right section is in the top five results.
Answered, cited the right section, and stated the fact.
Said “I don't have evidence” for things not in the record.
Prompt injections and false premises refused.
Requirement verdicts that match the expected one.
Evidence quotes found word for word in their source.
These are mock-mode scores: rule-based answers and verdicts, no model, $0. Retrieval, refusals, citation checks and the guards are the real code. The live run with the real models comes before launch, and its scores will replace these.

Why these fail in mock mode: the stand-in answers by quoting the best-matching sentence, so a false premise (“managed a team of twenty”) or a name clash (“Google” vs. the Google Maps note) gets a true but off-target quote. Nothing invented reaches the page, which is what the grounded score measures, but the answer misses the point. The live model is told never to name an employer, number or result the sources don't state; these cases stay listed until a live run shows them fixed.

How it's measured
- Retrieval: for each answerable question, the section that holds the answer must be among the five retrieved. Scored before any model runs.
- Answers: not refused, cites the expected section, and contains the expected fact (e.g. “$0.33”, “4 High”).
- Refusals and attacks: questions the record doesn't cover, false premises and prompt injections must end in the refusal. The trace names the guard that stopped each one.
- Fit verdicts: five job descriptions (AI engineer, full-stack Next.js, data engineer, frontend, and a deliberate poor fit: native iOS). Each requirement has an accepted verdict set, e.g. Kubernetes must be “no evidence”.
- Zero fabrication: every quote in a fit report is checked word for word against the section it links to, and every sentence of an answer must carry a citation. A failure here fails the build.
Run it yourself
The cases live in evals/cases.json. npm run eval runs them in mock mode; EVAL_LIVE=1 npm run eval runs them against the real models (a few cents). Try your own attacks on the break-it page.
