@porcuquine: @whyrusleeping and @nicola think this is done and specced. is this issue ready to close?

[porcuquine]

No: It's specced, but the implementation is not connected to the API. There is no way to actually get a piece inclusion proof yet, and there will need to be changes to how pieces are packed within sectors as part of the implementation. Those changes will probably want to filter back into the spec in some form as well.

Also, this is not P0.

@porcuquine, apologies for delay; i just saw your note in the spreadsheet online. i'll defer to your judgment on whether this should be p1 or p2, then. do you still agree it's launch-critical?

[porcuquine]

Probably P2 right now. My understanding is that it's need for launch, meaning mainnet — but it's explicitly not prioritized yet.
