Review Comment:
   This mirrors the raw range even when the real predicate uses `flt_grain` and 
filters a truncated timestamp expression. For a weekly upper bound, rows later 
in the final week still match `DATE_TRUNC(...) < until` but the raw partition 
predicate excludes them. Should grain-bearing filters skip mirroring (or use 
bounds that preserve the truncated predicate)?
