Rationale

Dimension	Rationale
Reliability	W3C Community Group specification — authoritative venue but explicitly marked as work-in-progress with "completely bogus content" warning. Never advanced beyond Editor's Draft.
Relevance	Directly addresses the query — this IS the credibility signals specification being asked about.
Bias flags	High risk for missing data — many sections contain "TBD" placeholders. The document is incomplete by design. Some concerns about selective reporting — the document catalogs "possible signals" without commitment to which should be used.
