Perhaps have a bit in the index mode for the file to say that the mode in the filesystem is unreliable, which gets set if a stat of the newly-written file doesn't match the mode it was supposed to have, or if git chmod is used to change it; then, if the bit is set, ignore the mode in the filesystem and just use the mode in the index.

This should prevent modes from magically changing, even if the user doesn't do anything special.
