Diagnosticity Analysis¶

Most Diagnostic Evidence¶

Evidence	Why Diagnostic
SRC04-E01	Verification Handbook is the most likely venue for operationalization — its absence there strongly discriminates H1 from H2
SRC02-E01	First Draft is the creators' own organization — if operationalization existed anywhere, it would be here

Least Diagnostic Evidence¶

Evidence	Why Non-Diagnostic
SRC05-E01	Secondary review — absence of implementation details could be an artifact of the review's scope

Outcome¶

Hypothesis supported: H2 — The taxonomy has been widely adopted as vocabulary and conceptual lens but not operationalized into structured classification procedures.

Hypotheses eliminated: H1 — No structured classification tools found. H3 — Significant real-world adoption demonstrated (EU policy, 37+ newsrooms, UNESCO).

Hypotheses inconclusive: None.
