Evidence
No evidence records attached yet — this claim is held on its source anchor alone: the ledger knows where the proposition is stated and has admitted no observation behind it. A source is not evidence.
an honest empty state
This claim is in the ledger but not in the current edition's featured set. Nothing here has been assessed — that absence is information, not an oversight.
Still missing: plain-language gloss, credibility assessment, diagnosticity assessment, strongest objection, what would change our mind. A claim gains them when an edition features it and the edition's adopted assessment supplies the full treatment — a decision the panel reviews, not a field anyone flips.
