Diagnosticity Analysis¶

Most Diagnostic Evidence¶

Evidence	Why Diagnostic
SRC01-E01	Legal consequence-calibrated thresholds clearly discriminate H1 from H2 — this concept is unambiguously absent from the reference set
SRC04-E01	FMEA's detection dimension is structurally novel — no reference framework assesses error detectability
SRC03-E01	Bradford Hill's overlap with GRADE discriminates H1 from H2 for this specific discipline

Least Diagnostic Evidence¶

Evidence	Why Non-Diagnostic
SRC05-E01	FTA is complementary to FMEA; its novelty assessment is partially dependent on FMEA's
SRC09-E01	CASP's overlap with Cochrane is expected and unsurprising

Outcome¶

Hypothesis supported: H1 — All eight disciplines are formal, and five of eight contribute novel concepts

Hypotheses eliminated: H3 — All disciplines clearly have formal methods

Hypotheses inconclusive: H2 — Partially correct (three disciplines are redundant) but overall H1 is better supported since five contribute novelty
