Ranging a map returned at the first failure, so an operator missing three
binaries was told about one, fixed it, reran, and was told about the next.
The function exists to stop the sweep once rather than fail per
implementation and seed.
Two identical runs also printed different errors, which is why this
reached master as a flake instead of a clean red.
resolveBinaries ranges a map, so with more than one binary absent the
error named whichever it reached first. The test passed locally only
because bun and sanderling were on PATH; on CI it was a three-way coin
flip.
installs, builds and serves each implementation on its own port, then hands the campaign tool the same seed slice, step budget and generator for all of them, so a difference between implementations is not a difference in exploration. the generator and platform are fixed rather than exposed.
