Wikipedia verifiability policy: all challenged material must carry an inline citation to a reliable published source
Quote (Wikipedia:Verifiability): "All quotations and any material challenged or likely to be challenged must be attributed to a reliable published source using an inline citation."
Source: https://en.wikipedia.org/wiki/Wikipedia:Verifiability
Confidence: Verified.
Use for Candid: Wikipedia's three interlocking core content policies are verifiability, no original research, and neutral point of view. Adapting just verifiability to the agency KB is the strongest single discipline — every claim node carries a source, every quote is exact, every confidence flag is honest. This entry itself follows that pattern.
