✓ Portable graph bundle live · download bundle · merged state

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

Star formation in M17 SW is globally driven by gravity but locally regulated by the magnetic field structure.

C2weakest assumption

The Skalidis-Tassis method applied to the polarization and ammonia data yields accurate plane-of-sky magnetic field strengths without significant residual errors from angle dispersion or unresolved structure (abstract and implied methods section).

C3one line summary

High-resolution magnetic field maps of M17 SW reveal gravity-dominated energy budget with magnetic fields regulating collapse and accretion channels in a near-equipartition state.
