Four headless facts: no .sbsar or .sbsar.meta remains; no surviving Assets/Packages/
ProjectSettings/GameData file names a removed Substance guid (44 tombstones: 41 sbsar
metas, 2 folder metas, the importer script guid); the SUBSTANCE_PLUGIN_ENABLED define,
LFS rule and manifest entries are gone; every repointed material names only textures
that resolve to a .meta outside the removed tree. Fails on b2322c4ce for those reasons.
