Operating Note: Domain Eval Fixtures (Content + SQL)

Domain fixtures are a second evaluation layer for lane-specific reliability.

Why this layer exists

Generic checks validate broad model behavior. Domain checks validate real production constraints:

• content voice compliance,
• SQL correctness at the right grain.

Practical setup

• keep fixtures versioned,
• run domain + generic checks in one weekly cycle,
• require both to pass before promotion.

Bottom line

Routing quality improves when lane-specific failure modes are tested explicitly, not inferred.
