| # Rust userinfo lookup and buffer ownership | |
| RE-895. Reproduce with `python3 scripts/analyze_rust_info_lookup.py`; focused validation: `cargo xtask test-group rust-info-lookup`. [Machine report](rust-info-lookup.json). | |
| Rust matches96 original70503 key/value and selector cases, preserving first-match case folding, incomplete-pair rejection, empty values, embedded NUL and null early exits. Oversized logical inputs reject without changing the selector. Native userinfo retrieval, raw pointer aliases and fatal semantics remain open. | |
| Original executable/native runtime and complete Linux/macOS Rust/Bevy/Solari acceptance remain unverified. | |
