iiuc, the following scenarios would also need to be handled for completeness:
- partial writes of payload, following the offset (i.e. when
s.ebuf = ebuf[:pos]assignment below panics) - finding the last segment with non-corrupted data (the existing last segment file may only have corrupted data if e.g. it's 0 byte or the first entry is corrupted). We should delete that file and attempt reading second-to-last one (preferably with recoverCorruptedTail=false)
- the last segment post-recovery must have non-zero entries or whatever is appropriate considering feat: TruncateFront & TruncateBack support truncating all entries #31
