Value is null but present stream is missing

Error message

Value is null but present stream is missing

What it means

Validation guard: a null check requires the present stream (presentStream == null here means all values assumed non-null) yet the skip path encounters an offset implying null entries — the row group's stream layout contradicts its metadata, i.e. file corruption.

Solutions

1. Restore/rewrite the corrupted file
2. Validate storage-level checksums and upload completeness
3. Use fault-tolerant reads to quarantine bad splits
