CONSTRUCTION_NOTE
Panel C reports a baseline difference-in-differences estimate from equation (3), displayed as a raw OLS coefficient and divided by the DHH pre-AI mean.
RESEARCH_LIMIT
A.9 does not explicitly label its parenthetical values or clustering. A.6 elsewhere labels SEs/clustering, but its exact binding to this row is not established here. Rounded displays do not establish exact division. Calendar dates and complete estimator/sample details are absent from the selected packet.

LEXICAL_NOTE
display preserves the PDF minus glyph; numeric_lexeme normalizes it to an ASCII sign without changing the value.
