evidence-boundary-discipline

State only what a dated source actually supports: fix the tense to the dateline, carry one provenance label across every surface, give every factual paragraph its own citation, and never let absence escalate into "does not exist". Use when writing or revising a knowledge page, monitor delta, entity section, or delivery table built from reports, press releases or partial legal text. Not for collecting or grading sources (that is claim auditing), and not for prose whose every claim is already primary-sourced.
