The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The combined velocity distribution of WNh, O If*/WN, and WNL very massive stars shows both slow, unejected objects (v_perp < 10 km s^{-1}) and stars dominated by fast, runaway velocities (v_perp > 24 km s^{-1}), supporting that VMS ages are comparable to the dynamical ejection timescale (~1.5 Myr).

C2weakest assumption

That the observed transverse velocity distributions directly trace distinct ejection mechanisms without major biases from projection effects, incomplete sampling, or unaccounted radial velocity components.

C3one line summary

Gaia DR3 proper motions of LMC Wolf-Rayet stars reveal distinct velocity distributions across subtypes, indicating dynamical ejections dominate some populations while others arise from binary mass transfer or explosive mergers.
