What the abbreviations in a chart actually mean. 80 codes across nine categories, the SOAP structure they sit inside, and the ones that mean two different things.
Mission
Replace this paragraph with one or two sentences on what this site covers, who it serves, and what the reader will gain. Specific beats generic. Name the topic, the source material, the gap you fill.
Editorial standard
- Primary sources cited inline on every non-obvious factual claim.
- Every long-form page lists its sources at the bottom with a verification date.
- Where sources disagree, the disagreement is surfaced, not papered over.
- Time-sensitive claims about third parties are re-checked on a published cadence and the article's modified date is updated.
- Corrections and contributions welcome via email and acknowledged in the article.
