# Rust Source
Real OpenHuman Rust files. The source compressor keeps imports, signatures, and top-level structure while collapsing large bodies when useful.
Each row links to the full raw input and the exact compacted output used by the benchmark.

## What TinyJuice Is Doing
The code path keeps the navigation surface: imports, signatures, top-level items, and important comments. Large function bodies can be collapsed and recovered through CCR.
