> A merkle tree file may be corrupted during write or by some other error. This
> should only be a temporary problem since the scanner will rewrite it on its
> next run. Until that happens failures should be handled accordingly:
> * Clients calling the readMerkleTree API should be able to cleanly fail on a
> corrupted file. The server does not deserialize it before sending.
> * Reconciliation should regenerate a local checksum file if it is corrupted,
> as if it does not exist.
> * File write can be done by renaming a temp file into place to avoid
> corruption from partial writes. The file would either be present or absent if
> a write fails, but not partially written.
> * Tests using corrupted files should be added.
