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

We recover the correct mass of Sgr A*, and our stellar mass distributions are in agreement with the literature, albeit with larger uncertainties.

C2weakest assumption

The modelling assumes the gravitational potential is time-independent and that the observed kinematics can be reproduced by a steady-state orbit library in a triaxial potential whose parameters are adjusted to fit the data.

C3one line summary

Triaxial dynamical modelling of the Galactic centre recovers the known mass of Sgr A* and shows the nuclear structures are mildly triaxial with radially varying orbit populations dominated by hot/warm orbits inside a few parsecs and cold orbits farther out.
