nor package-group name derives a persistent subdirectory. The delegated driver
may create a missing store only after graph and request preflight, and rolls
back newly created empty prefixes if later setup fails. Every reuse decision
stays with the driver's content-identity contract above. `-w` and test `-c` do
not mix — the coordinator rejects the combination rather than guess which
artifact tree the caller owns. `test-library` uses exactly this: one
