Ambiguous Artifact ID

The artifact hash prefix 215c is ambiguous and might mean any of the following:

     'repository is corrupt' says a repository cannot be read, not what in it is unreadable -- and the walk that discovers it visits every artifact in the store, minutes on a large one. Whoever holds the broken repository was left bisecting it or attaching a debugger.

     The derive now records which artifact it rejected and why; openRepo reports it, so every verb's open gets the name. Plain data, no allocation, so it survives the errdefer that tears down a half-built view. Repository.open clears it per attempt because callers declare a Repository undefined.

     Also splits open's two identical diagnostics: deriving the view and reopening the log for materialization both printed the same line, which made a failure in one indistinguishable from the other. (#42) (user: dmestas, size: 58776) [annotate] [blame] [check-ins using]
