Evidence vs. Hypotheses Matrix¶

Evidence	H1 (All confirmed)	H2 (Material errors)	H3 (Confirmed with discrepancies)
SRC01-E01: Session details and Moore as audience member	-	--	++
SRC01-E02: 90% Linux prediction quote verbatim	+	--	++
SRC01-E03: SCO concern with OSBC institutional context	-	-	++
SRC01-E04: Additional Moore quotes omitted by R0045	--	N/A	++

Diagnosticity Analysis¶

Evidence	Most Diagnostic For	Reasoning
SRC01-E01	H3 over H1	The "audience member" vs. "spoke at" framing difference is the key discriminator between H1 (perfect match) and H3 (confirmed with discrepancies). It is not a material error (ruling out H2) but it is a meaningful framing difference (ruling out H1).
SRC01-E03	H3 over H1	The institutional prohibition context adds meaning that R0045 Q004 did not capture. Again, not a factual error but a significant omission.
SRC01-E04	H3 over H1	The volume of omitted content demonstrates R0045 Q004 performed selective extraction, not comprehensive source analysis.
SRC01-E02	H1/H3 over H2	The verbatim quote match eliminates H2 for the core prediction claim.

Outcome¶

H3 is the best-supported hypothesis. All four evidence items are consistent with H3 (core facts confirmed, framing discrepancies and omissions present). H1 is eliminated by evidence E01, E03, and E04. H2 is eliminated by E01 and E02 (no material factual errors found).
