Field notebook I
Tone travels at an angle.
A sentence is never received in isolation. It crosses desks, borders, hierarchies, remembered wars, family habits, and the invisible protocols of rooms where nobody says exactly what they mean.
Global tone checking is the study of that crossing: whether a direct phrase reads as efficient or hostile; whether humility sounds respectful or evasive; whether silence is an omission, an answer, or the most precise sentence in the exchange.
This dossier treats tone as scholarly material. Not sentiment, not etiquette, but evidence: a pressure mark left by culture on the surface of language.
