This is the message as the crawl holds it, before anything
here touched it. What the conversation shows has been through ingest: transfer
encodings decoded, attachments dropped, quote markers repaired, and the
archiver’s ? resolved into quotation marks and dashes. Those
repairs are judgements and some of them are wrong, which is what this page is
for. Email addresses are obscured here as they are everywhere else on the site,
so it is before our repairs rather than byte for byte.

You can't say "almost certainly" for such a short string without applying some kind of statistical test. That aside, there is the strong likelihood that even if the digits were not selected randomly, they do not mean anything in particular. Perhaps Wolfe felt that it would add verisimiltude to have a low entropy string, certain components of which would have from a restricted set indicating type or origin of items stored. That doesn't mean he has thought about what exactly they represent in a given instance. - Gerry Quinn
