| # Rust case-insensitive field search and signed-byte comparator | |
| RE-857. Reproduce with `python3 scripts/analyze_rust_entity_field.py`; focused validation: `cargo xtask test-group rust-entity-field`. [Machine report](rust-entity-field.json). | |
| Rust matches 150 original field searches and 256 comparator cases, preserving nullable ordering, signed high bytes, ASCII folding, embedded NUL and count gates. The API receives resolved logical fields with bounded entity/string sizes; raw pointer/offset ABI remains outside this safe contract. | |
| Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified. | |
