+This seems conclusive that the repair is somehow triggering unncessarily
+and also corrupting the repo in this situation.
+
+The comment #3 log shows that the repair is started, and then 1 minute
+later a git object is missing.
+
+(It's odd that log shows a second fsck run after the repair was already
+triggered. I do not see a way that this would happen unless fscks are
+scheduled very close together.)
+
+The automatic repair is supposed to be a non-destructive repair; the
+destructive repair only happens after prompting in the UI.
+
+This also reminds me of a persistent issue with a git-annex repo, using the
+assistant, on my sister's laptop corrupting itself.

+The repair process moves all pack files to a temp dir and then unpacks the
+loose objects from them. So, there is a time window, when the repair is
+running, where git objects that were present before will be missing. And if
+the assistant stops before that is complete, it would leave it in that
+state. Unpacking pack files can take a long time, so this might
+be a sufficient explanation.
+
+But then, something must be causing it to incorrectly think it needs
+a repair in the first place. Assuming it is incorrect, of course. Either git
+fsck is exiting nonzero for some reason, or git-annex is thinking
+it sees git fsck complain about a missing object, that is not really
+missing. While there are fsck outputs that it can misinterpret, it
+double-checks by trying to cat the object, which should avoid the latter
+problem.

+To avoid moving the pack files, repair could set `GIT_OBJECT_DIRECTORY`
+to a temp directory, and copy each pack file into it in turn, and unpack.
+And after each unpack, move the unpacked objects from the temp directory to
+the real object directory, followed by deleting the pack file (in case it's

+Removing repair from the assistant (and git-annex repair) should be on the
+table as a solution to this. It's a whole lot of complexity that might fix
+a few user's repos sometimes, but is outside of git-annex's scope and is
+mostly only used by assistant users.
