- Establishment/containment: miss-first ternary polarity, else-if head exits, bare-block vs alias guards, break/continue exit guards, post-loop re-tests, while-condition guards, born-narrowed declarations (2390-2396) - Kill routing: branch/switch-arm/reassignment-polarity kills at merges, and kills riding return/break/labeled-break/continue/throw edges (2397-2406) - Terminality: infinite-loop sealing and re-opening, loop-body returns, stacked and trailing-empty case labels, defaultless exhaustive switches (2407-2411) - do-while trailing tests under body guards, kills, continue, and break, plus spread-arm ternary lowering shapes, ?? null identity, float-lane bounds, IEEE remainder corners, and parameter null reassignment (2412-2423) - Order-parity baselines re-recorded for the new entries (pure addition)
