Every piece of reference information passes through one gate before it can appear. The gate is ordinary deterministic code, not a language model. A statement is shown only when it carries an identifier, the exact wording the source supports, a working link to that source, the kind of source, the population it applies to, its date, its limitations, a version and a date by which it must be checked again.
Anything that fails is replaced on screen by two words: RESEARCH REQUIRED. Every statement that passes has a View evidence sheet showing all of the above. Wording that promises outcomes or tells a person what to do is rejected automatically, and the build fails if an unsupported statement slips in.

Badges are monochrome. A source type is a description, not a score. Today's summaries are source-checked with AI assistance and have not been independently reviewed by a named clinician; the product says this on every sheet rather than implying otherwise.
