Shake cache is shared between multiple targets

[srid]

Different target directories use the same Shake cache.

Not really. The cache key already contains the full target path. However if the user deletes a target file, that is not taken into the account - and Shake thinks that file need not be recreated because it is cached (at least, that's my theory).

[srid]

Probably to do with symlinks. To test this theory, resolve the filepath to remove any symlinks before using it in cacheKey and cacheClosure (Rib.Shake.writeFileCached).

EDIT: Just check for missing files, and invalidate their cache. To reproduce, rm -rf ./b and re-run the app.
