It seems to be an import pipeline bug.

Photos does a lot of extra work on import (merging RAW+JPEG pairs, generating previews, database indexing, optional deletion), so my guess is a concurrency bug where a buffer gets reused or a file handle is closed before the copy finishes.

Rare, nondeterministic corruption fits the profile.

This is also my guess. It's really a bummer, and I'd report it to Apple but since it's nondeterministic I have no idea how to provide repro steps.

iTunes Match has routinely just... removed/greyed out files that I've had uploaded, and I've reported this to Apple over and over again, with exactly zero explanation of why or how to avoid it. To this day it still does it.
