FUT modes (Seasons/Tournaments/FUT Champions) and the club-identity service are
disabled in this emulator, so these GET reads return {} verbatim from the Python
oracle. Serve them directly from Rust via a new Route::FeatureOffEmpty +
non_economy::feature_off_body() -> {} (byte-identical to the flag-off oracle),
reducing the proxied Python surface.
- The mutating club rename (user/club) stays on Python (needs a Core write).
- Enabling a mode later requires a real Rust handler here, never a Python
fallback (no split authority).
- classify tests: 5 routes owned + user/club/wrong-method lookalikes stay
Passthrough; updated the stale clubUser assertion.
- Deployed to prod-host 2026-08-17; verified owner=RUST 200 {} for all five.
Docs: PRODUCTION_AUTHORITY_MATRIX + PYTHON_RETIREMENT_PLAN updated.
