Diagnosticity Analysis

Most Diagnostic Evidence

Evidence ID Why Diagnostic
SRC03-E01 The only evidence that distinguishes H2 from H3 — the community guide's 14-language availability contradicts H2 while supporting H3

Least Diagnostic Evidence

Evidence ID Why Non-Diagnostic
SRC01-E01, SRC02-E01 Both support H2 and H3 equally — English-only vendor guides are consistent with both "not addressed" and "partially addressed"

Outcome

Hypothesis supported: H3 — Coverage is partial and inconsistent; community leads vendors

Hypotheses eliminated: H1 — No vendor guide meets the bar of "well-addressed"

Hypotheses inconclusive: H2 — Partially supported for vendors but overstates the case given the community resource
