Day 6: my language now compiles to WebAssembly — and I emit the bytes by hand

Short summary

LOOM, an open-source language for verifying AI-written code, now compiles to WebAssembly using hand-emitted bytecode (no external toolchain). Day 6 demonstrates that Fibonacci, list operations, and sum types execute identically across interpreter, Python, JavaScript, and WebAssembly runtimes, proving effects and provenance hold across all targets. A solo builder also deployed a trust layer that signs foreign-code vouching, preventing unverified components from laundering through system boundaries.

• •Converts to WebAssembly with zero dependencies by hand-emitting bytecode
• •Fibonacci and list operations verified identically across four runtime targets (interpreter, Python, JS, Wasm)
• •Trust layer now includes attestation for signed foreign components—prevents unverified code laundering
