Jira issue: CRDB-65030

Start with pkg/storage/pebble.go:1436 and the linked Sentry report, then trace the cited Pebble compaction and checksum-validation frames under external/com_github_cockroachdb_pebble. The report provides no reproduction steps or proposed change, so the cause and completion criteria must be established before implementation.

Written by the indexing model from the issue text.
