Good catch @vustef. Sequential-fill assumes we can see all row groups, and row-group pruning would break that under mixed metadata — silent stale numbers are worse than a clean failure. Refining the plan: - **All ordinals present** → honor them. - **No ordinals present** → sequential-fill. - **Mixed** → leave metadata untouched; row numbering does not work for this file (deterministic across queries, regardless of pruning). Non-row-number reads succeed in all three cases — that was the original bug. -- This is an automated message from the Apache Git Service.
