“A 2026 Nature paper reported S301, a fast-orbiting star near Sagittarius A*, and assessed its potential for measuring the black hole’s spin.”

Checks out so far. 1 holds up so far; 1 not a checkable fact.

0.9820 under ledger-default@0.3.0 at snapshot 27745 for all claims together. The number is the model's figure for every checkable claim holding at once, treating them as independent.
