+
+For each planted bug, determine if the report identified it. A bug counts as
+"detected" if the report describes the same defect, even if the wording differs.
+Use the detection_hint keywords as guidance.
+
+Also count false positives: issues in the report that don't correspond to any
+planted bug AND aren't legitimate issues with the page.
+
+Respond with ONLY valid JSON:
+{
+ "detected": ["bug-id-1", "bug-id-2"],
+ "missed": ["bug-id-3"],
+ "false_positives": 0,
+ "detection_rate": 2,
+ "evidence_quality": 4,
+ "reasoning": "brief explanation"
+}
+
+Rules:
+- "detected" and "missed" arrays must only contain IDs from the ground truth: ${groundTruth.bugs.map((b: any) => b.id).join(', ')}
+- detection_rate = length of detected array
+- evidence_quality (1-5): Do detected bugs have screenshots, repro steps, or specific element references?
+ 5 = excellent evidence for every bug, 1 = no evidence at all`);
