Why this source is in the Atlas
A data-side reassessment that runs against the expected direction, finding newer data allows slightly more freedom in the criteria. Cited so the atlas does not present the observational trend as one-way.
- Verification label
- Verified. This confirms identifier resolution and placement in the literature map, not the correctness of the paper’s argument.

- ds-001
The observed late-time acceleration of the universe is standardly modeled with a small positive cosmological constant, and current data place the dark-energy equation of state near w = −1.
- ds-010
If metastable de Sitter vacua are excluded, dark energy would have to be dynamical — a rolling scalar field rather than a constant.
