"""`okf project`: one folder in, one bundle plus one skill out.

The command adds no rule and owns no flag that changes a bundle's bytes, so
these tests are mostly about that: the project bundle must be the SAME bytes
`okf build` writes for the same folder at the same stamp, or there are two
build paths and the reports are pinned to one of them.
