SYNTHETIC ACCEPTANCE FIXTURE

Manual arithmetic fixture, not a complete export:
Public placeholder page: https://firm.example.invalid/service
Query: synthetic service
Previous matched period: 10 clicks / 100 impressions
Current matched period: 8 clicks / 200 impressions
No other rows, filters or rankings are asserted.

EXPECTED RESULT
Previous CTR is 10%; current CTR is 4%; change is -6 percentage points. This is a review signal, not proof of a bad title or revenue loss. An incomplete export blocks completeness claims.

This is a test specification, not output from a tested integration.
