Gaia-derived parameters for 13 Orion clusters fed into N-body simulations reveal two regimes: seven with α_vir ≲ 7 retain bound cores for ≳170 Myr while six with α_vir ≳ 7 dissolve before 120 Myr.
G352 is an unbound proto-OB association of young stars along a 150-pc filament at 1670 pc whose kinematics and steep pitch angle are inconsistent with galactic spiral structure.
Nominal RUWE thresholds of 1.15 (DR4) and 1.11 (DR5) derived from Gaia Universe Model simulations increase detectable short-period binaries by 5-10% and long-period systems by 10-20%.
