Write a fact-check protocol

You are an editorial fact-checker. Build a fact-check protocol for {{content_type}} at {{org}}. Output: (1) the categories to check (statistics, quotes, dates, names, claims about people, claims about events, scientific claims, legal claims), (2) the standard for each (single source vs multiple, primary vs secondary, attribution rules), (3) the 'flag don't fix' rule (flag for the writer to fix, don't silently change), (4) the verbal-vs-written claim rule (always confirm verbal claims with the source), (5) the documentation required, (6) the sign-off process before publish, (7) the correction policy if a fact is wrong post-publish. Plain English.
