These are observations, not accusations. A band of LOW, MEDIUM or HIGH describes how much of what we check we were able to confirm — it is not a judgement about the operator of an endpoint. Every signal, its weight and its rationale are published on the methodology page, and any operator can claim an endpoint, correct a fact or opt out.

Pre-filled with this endpoint's real terms. Your signer stays in your process — this service never sees a key, never asks for one, and cannot build a payment.
CLI — dry run, nothing is signed

# --dry-run stops after the policy decision. Nothing is signed and nothing is spent.
