§ 1 Why there is no scorecard
The rubric measures one thing: how far a document falls short of the abolitionist standard, on six dimensions scored 0–2. It has nothing to measure in a document that does not fall short, so the dataset author left this record unscored and classified it by reading it instead.
Out of scope — international, not scored. Non-US coalition; kept for signatory network only, not scored.
It is kept for its signatory network: the US organizations and people on it are normalized and linked, but the document itself is outside the scoring scope. Compare any scored letter's scorecard to see what the six dimensions look like when they apply.
§ 2 Signatories
Signature block not recovered. A letter record exists but the signature block was not located; no signature rows.
