What
Removing a message from a transcript stored in the newer on-disk format used to abandon the deletion when reading the end of the file failed. It now retries with a record-by-record scan that pages backwards through the file.
Details
The fallback only runs when the read error matches a specific recoverable case; other errors still abandon as before.
The scan is bounded by a sliding window size, a page size and a maximum number of bytes read.
It logs its own failure, Tombstone removal abandoned: stream stat failed, when it cannot even size the file.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
