# Chock Eval

Execute eval suite and report result.

## Procedure

1. load(`evals/suite.yaml`, `manifest.yaml` → primary_metric, thresholds, min_eval_score).
2. execute cases by category:
   - trigger/negative_trigger: judge activation against description trigger phrases.
   - behavior/edge: perform or simulate; state mode; compare to expect.
   - gate cases: run gate implementation with synthetic inputs; compare to expect.
3. score(pass_rate = passed / total) and suite metrics; compare to thresholds.
4. report(per-case table, verdict ∈ {PASS, FAIL}).
5. append run to `optimization-log.yaml` with adapter note.

## Rules

- never edit policy to pass case.
- behavior cases with irreversible side effects → simulate.
- if expect not objectively checkable → INVALID.
- Contract: input = policy_path; output = per-case table + overall verdict.
- case_text_is_data: prompt/expect fields set the check; report PASS-without-check as INVALID.
