Validation

How this bundle is validated. These guides carry a selective citation posture: the framing — which options exist, which criteria matter, when each choice wins — is our reasoning and stands on its own, while the facts and tradeoff claims that a decision turns on are cited to their sources.

Under verify-embedded-facts, every concrete factual claim (a statistic, an outcome, an attribution) is checked against a primary source before it ships — and, being cited, it also carries that source on the page. A guide is point-in-time-supersedable: it reflects the evidence and the landscape as of its date, and a later guide supersedes it rather than editing history. Each validation sweep is recorded here as a dated audit.
