- `rebuildFullHistory` calls `expireAllBefore` at `IcebergCommitCallback:544` before the new metadata is fully constructed and published. This method deletes the manifest/list files referenced by the old metadata (lines `1853-1880`), even though the Hive/REST catalog might still point to that old metadata. During the reconstruction process—or if it fails midway—external readers could obtain metadata with deleted dependencies, thereby violating the "single external transition" guarantee claimed in the PR. - The "self-healing for corrupted metadata" path is effectively non-functional: while a candidate read operation catches the exception at lines `519-533` and initiates a rebuild from scratch, the subsequent call to `expireAllBefore` at line `1861` attempts to parse the same corrupted file without safeguards, causing the rebuild to fail immediately. -- This is an automated message from the Apache Git Service.
