the {adapter} adapter declares the `group` capability but has no `executeGroupLevel(query, aggregates, request)`, so grouping is not pushed and the grid is left to group whatever rows it holds. Implement the method or drop the capability.

Since

1.63.0

What happened

A capability declared without the method behind it is the one thing the planner cannot see - it is handed capabilities, not the adapter. The query is re-planned without grouping, so lastPlan() reports the query that actually ran and names group among the unpushed work, and the grid groups whatever rows it has.

The fix

Implement executeGroupLevel, or stop declaring the group capability.
