hot index root audit
A PostgreSQL storage/index fixture maintainer checks which supplied page tuple an initial index-root HOT search may actually return,rather than treating every snapshot-visible physical tuple as reachable from that index entry. PostgreSQL18 first_call=true model only. Visibility and resolved updater are supplied. No MVCC execution,page validity or security diagnosis. Unknown/revisit limits explicit. Fixed price also for successful unknown;invalid profile HTTP400 before settlement. A.
