Fabricated coverage limits
v18 outputs specific dollar amounts for coverage that don't appear in retrieved context.
Representative example
Output: 'Your policy covers up to $25,000 in collision damage' — context only states 'collision coverage applies'.
Sample failures (1)

Input
What's my collision coverage limit on policy P-77241?
Retrieved context
Policy P-77241 — collision coverage applies. Comprehensive coverage applies. Deductible: $500.
Output
Your policy P-77241 covers up to $25,000 in collision damage with a $500 deductible.
Expected
Collision coverage applies; for the specific limit, please refer to your declarations page or contact your agent.
Evaluator rationale: Output fabricates a specific $25,000 limit not present in retrieved context.
