   I don't know filecoin well, but using chain.love as a lotus-lite
   endpoint seems to make it hard to discern things.  I can't search the
   chain for messages.
   lotus state miner-info f0410001
   gives an "actor not found" error
   lotus state lookup --reverse f0410001
   gives an "unknown actor code" error

   Private keys are long random byte strings.
   I don't immediately see a way in the cli interface to renegotiate a
   deal.  The approach appears to be to simply redeal the data, even with
   the same party.
   I'm holding a goal of pursuing programmatic access to data via e.g.
   git-annex, rclone, or minio.  I think a simple implementation that
   calls the cli would not be hard.
