Checked, not settled
“NASA’s Webb observations of IC 348 found brown dwarfs as small as twice Jupiter’s mass, and one of the lightest showed signs of a disk.”
Checks out so far. 2 hold up so far.
0.9900 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.
The statement as a whole, read from the 2 claims below. Each claim is scored on its own; this reading only counts them. Provisional until audited.
