Claim: concrete, compiler-neutral in-memory and on-disk representations exist and are usable today. Implementation: an open IPR library under MIT captures a minimal, expression-based in-memory model; a binary IFC format is open on GitHub stores partitions, string tables, 32-bit typed references and a header with checksum. Results: MSVC emits IFCs, they’re roughly 10× smaller than PCHs, load back into compilers, and enable tooling (bindings, JIT). Status: spec and code need cross-compiler adapters and community contributions.
