> *Description:*
> On the read path, ensure that the data type of lookup set literals is
> compatible with the SI column’s declared type. Specifically:
> * Allow index lookup only when types matches
> * If incompatible:
> ** *Preferred behavior:* Fallback to full table scan (no index)
> ** *Alternative behavior:* Throw query error
> *Label:* {{{}blocker{}}}, {{{}si{}}}, {{lookup-validation}}
