WP-013 — a defect deferred on purpose

HorizontalFlip mirrors a rotated box by negating theta, and the commit documents re-canonicalization as a Phase 8 concern rather than doing it. That deferral was correct at the time and became a live defect the moment WP-058 removed the guards — the note is what made it findable.
