Query	Q003

Matrix¶

	H1: Formal bridge exists	H2: Partial bridge exists	H3: No bridging at all
SRC01-E01: Ibrahim et al. use both vocabulary sets in unified framework	-	++	--
SRC02-E01: CSET title bridges traditions; shared authorship	-	+	--
SRC03-E01: Malmqvist treats sycophancy as purely technical	N/A	+	+

Legend: - ++ Strongly supports - + Supports - -- Strongly contradicts - - Contradicts - N/A Not applicable to this hypothesis

Diagnosticity Analysis¶

Most Diagnostic Evidence¶

Evidence	Why Diagnostic
SRC01-E01	The single most discriminating source — eliminates H3 (some bridging exists) while preventing H1 (bridging is functional, not formal/deliberate)

Least Diagnostic Evidence¶

Evidence	Why Non-Diagnostic
SRC03-E01	Demonstrates the silo exists but does not discriminate between H2 and H3 (both predict siloed work exists)

Outcome¶

Hypothesis supported: H2 — Partial, functional vocabulary bridging exists in at least one paper (Ibrahim et al.) and one policy brief (CSET), but no formal, deliberate vocabulary mapping has been published.

Hypotheses eliminated: H1 — No formal bridge found. H3 — Ibrahim et al. demonstrates at least functional bridging.

Hypotheses inconclusive: None.
