Interesting timing. We have been working on something that takes the opposite design philosophy. JSIR is designed for high-fidelity round-trips back to source, preserving all information a human author put in. That makes sense when the consumer is a human-facing tool like a deobfuscator or transpiler.

We have been exploring what an IR looks like when the author is an AI and the consumer is a compiler, and no human needs to read the output at all. ARIA (aria-ir.org) goes the other direction from JSIR. No source round-trip, no ergonomic abstractions, but first-class intent annotations, declared effects verified at compile time, and compile-time memory safety.

The use cases are orthogonal. JSIR is the right tool when you need to understand and transform code humans wrote. ARIA is the right tool when you want the AI to skip the human-readable layer entirely.

The JSIR paper on combining Gemini and JSIR for deobfuscation is a good example of where the two worlds might intersect. Curious whether you have thought about what properties an IR should have to make that LLM reasoning more reliable.
