Arm effect 7 after the wheel-reset target, select it on the next effect line, and spawn a second visible live ball when record 149 is consumed. Advance the second ball through recovered line, circle, ball-ball, magnetic, and scoring collisions independently. During multiball, draining one ball leaves the other active without consuming a remaining player ball. Include secondary state in deterministic traces and finite-state validation. Test Plan: - `cargo test --all-targets` -- 52 passed - `cargo clippy --all-targets -- -D warnings` -- passed - production build plus Windows GNU and macOS checks -- passed - effect-seven spawn, movement, and single-drain lifecycle test -- passed - `git diff --cached --check` -- passed
