Read the facts snapshot with mesh-sdk's go/facts, formats 1 and 2, and keep writing format 1 (issue 1390, 3 of 4)

Browse Source 
The merge gate, the build seat's check and the facts writer import the snapshot's type from mesh-sdk (go/facts), whose reader takes formats 1 and 2 and refuses a newer one. The writer keeps writing format 1 (writtenFormat); moving it to 2 is a release of its own (novox/hq ADR 0456). A test shows the writer writes format 1, carries no grants or bindings, and the reader takes both formats and refuses a newer one.
