day_38__starting_git_repo_repair.mdwn

Goal for the rest of the month is to build automatic recovery git
repository corruption. Spent today investigating how to do it and came up
with a fairly [[detailed_design|design/assistant/disaster_recovery]]. It
will have two parts, first to handle repository problems that can be fixed
by fetching objects from remotes, and secondly to recover from problems
where data never got sent to a remote, and has been lost.

In either case, the assistant should be able to detect the problem and
automatically recover well enough to keep running. Since this also affects
non-git-annex repositories, it will also be available in a standalone
`git-recover-repository` command.
