"""Workspace manifests for the cases of an independent population file (ai-service-plane task 4).

``ousast plane workspaces <population.toml> [--out DIR]`` writes one ax ``Workspace`` per case pin (vulnerable,
fixed, benign base, benign tip) with the case's repository URL (checked out at ``<path>/repo``, depth 1) and the
pinned commit in the ``openultrasast.io/git-commits`` annotation (ax's ``GitRepo`` has no commit field), so a Run
binds a case at a pin by name. The layout of a case is that of ``benchmarks/independent/evaluate.py``'s ``pins()``.
