Brand stays in import path only; symbols, env vars, and exports are brand-neutral. One-release backwards-compat shim reads deprecated LUX_ names with deprecation log. Env: CRYPTO_BACKEND, CRYPTO_DIR, CRYPTO_BUILD_DIR, CRYPTO_LIB_DIR, CRYPTO_LIB are canonical. Rust: idiomatic Secp256k1Status enum; extern fn names dropped lux_ prefix. TS/Python: cryptoAvailable / crypto_available; FFI symbol strings drop lux_ prefix to match renamed C-ABI in luxcpp/crypto. cabi/main.go: //export names drop lux_ prefix (mlkem768_*, mldsa65_*).
