• The InstanceInformation interface is not defined
• installationHandle is an object and there is no corresponding interface (i don't know whether it should)
• getInstance is said to "Credibly get the instance from the instanceHandle", but returns an InstanceInformation (is "instance" the same thing than "InstanceInformation"?)
• A bit like for contractHost ( Contract Host without installations #95 ), it's not clear to me how much the installation step is worth the cost of adding another concept. zoe.install(source, terms) (or any better name) could work

• The name burnEscrowReceipt doesn't seem to convey what the method does. While assay.burnAll refers to the destruction of some extent of the assay, burnEscrowReceipt seems to me like it's more of a "transformation" or "exchange" (receipt against offer handle + rules) than a destruction. Maybe "transform" properly conveys the idea of something that disappears and something else appears

Thanks for this feedback! Please keep it coming. I think all of the things you mentioned are in flux, so I'll try to make sure that our solutions meet the issues that you've described here.

this was issue 219 in the old ERTP repo, and part of the "Zoe - immediate future" project

Closing this in favor of an updated #496
