Building Ephemeral Virtual Filesystems for WebAssembly
summary
Claims an alternative to host-backed storage by shipping an in-memory VFS inside modules, implements minimal POSIX calls via custom libc bindings, and wires that into a serverless runtime built in Go and Rust called Scale Functions. A demo opened 50 files from Rust using standard fs APIs and printed descriptors; the spike runs but is ephemeral only with no built-in persistence and needs more work on size, syscall coverage, and durability.
