Treat persisted raw page owner entries as a validated set, not a read_dir-order prefix, so restart scans can consume committed owner pages without recounting them against the raw enumeration budget. Commit checkpointed partial pages, validate owner parent/generation/digests before the skip oracle, and fail closed on duplicate/corrupt page state.
Extend the real scanner restart driver to enforce fixed raw-entry and object budgets across fresh OS processes, and report owner-index coverage in each worker round.

Record bounded first/last raw entry markers in the restart diagnostic worker and have the driver classify repeated raw windows when retained coverage does not advance.
