Stale sweep identified generated anchors by collection membership and role, so an author's hull-collider in
Generated was deleted. Generated anchors now carry aetheria.generated; the sweep removes only those. New smoke
pass package_asymmetric_pass: an L-shaped render hull pins tractor X and shield centre to the bounds centre,
a Source-only ship pins that generation never reads the Source fallback, and a collider placed in Generated
survives Package. All commits build.
