The lead's ruling on finding 1: an entry gains inputs (what its fingerprint is
computed from, the toolchains used, problems, warnings, named paths, the source
revisions it was taken in and its fingerprint moved at) and packages becomes
name to version, so the indexer's view of the trunk can be read back from the
newest trunk revision alone (ModuleValueOf). A revision's entries are the values
the recompute wrote, not the values it started from.
