Diagnosticity Analysis¶
Most diagnostic evidence:
- SRC04-E01, SRC05-E01, SRC06-E01 — These three sources are the most diagnostic because they simultaneously eliminate H2 (features exist) and H1 (not comprehensive), clearly supporting H3 (isolated features only). They are the pivot evidence that distinguishes between the three hypotheses.
Least diagnostic evidence:
- SRC03-E01 — Elicit's absence of target features is consistent with both H2 and H3, making it less discriminating.
Outcome¶
H3 (isolated features only) is strongly supported by all seven evidence items. H1 (comprehensive tools) is eliminated. H2 (no features at all) is eliminated by three sources showing partial implementations. The matrix clearly favors H3.
