What's the material difference between a Merkle tree hash and an OSTree 
ref (in the way BuildStream uses refs)? It's my understanding that our 
OSTree refs are a unique identifier for the pre-build conditions, plus 
the project and artifact name, while a Merkle hash would be a unique 
identifier for the results of the build, but is there some other 
difference I should know about?

(Reading through the rest of the proposal at the moment, looks good!)
