   Thanks @felipepessoto. All three findings are confirmed and addressed:
   - P1 (1b486cca6): plans that call a counter now force 
`expression.eval_simplified=false` after user overrides. I added the regression 
you described.
   - Both P2s (7f5c7a3a0): the guard is now an allowlist of the parents Delta 
DML generates. Nullable ancestors, lambdas, conditions, AND/OR and everything 
else fall back.
   
   The description now has the scope statement. While checking I found one more 
gap, which already exists on main and which this PR does not change. Velox can 
push a hash-join dynamic filter below the projection that counts 
`numSourceRows`, so that metric can undercount for an inner-join MERGE with a 
broadcast target. Only that metric is affected; table rows and CDF are not. I 
noted it in the description and will raise it separately.
