Nothing on this site asserts a requirement without a source you can open and read yourself.

Source hierarchy

How we weigh evidence

Tier 1 — Normative primary sources

RFCs, FIPS publications, CA/Browser Forum requirements and ballots, root-program policies.

Tier 2 — Official explanatory sources

Working-group drafts, browser and CA announcements, government guidance.

Tier 3 — Expert analysis

Named practitioner and research commentary, clearly attributed and labelled as interpretation.

Tier 4 — Signals

Mailing lists, incident reports and industry reporting used to detect change, never to assert it.
