# Rust raw comparator and eligible rank publication primitives

RE-776. Reproduce with `python3 scripts/analyze_rust_ranking.py`; validate with `cargo xtask test-group gameplay`. See the [machine report](rust-ranking.json).

Added typed ranking clients, raw source comparator and caller-ordered rank publication with permutation/participant validation. Four Rust unit tests cover prefilter quirks, signed and special-mode priorities, ties/team words and invalid domains. Actual aligned small sorting remains in source evidence; Rust sorting, publication callbacks, larger client domains and native/platform parity remain open.

No original executable/full VM/native world collision or rendering runs. Supplied callback/native responses and fixture domains remain explicit; complete macOS/Linux Rust/Bevy/Solari gameplay remains open.
