Resolve ASCII case differences in guest paths and mount aliases while preferring exact names and rejecting ambiguous fallback matches. Preserve new filenames and host roots. Five filesystem tests pass; Skyrim now loads its INI and shader archives, initializes Vulkan and uploads intro textures instead of dereferencing null shader metadata. Written with AI assistance.
