Evidence tier

Every real claim on this site comes with a confidence rating, on a six-step scale: Narrated → Observed → Replicated → Causally Supported → Cross Evaluator → Real World Corroborated. We show each claim at its tier and never higher.

Narrated means we've said it but haven't shown it yet. That covers most of our own founding claims right now. Exactly what each higher tier requires is still being worked out in M-1. Until it is, nothing here goes above Narrated.
