- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage.

The time qualifiers are correctly null since the passage provides no specific temporal scope ('still manufactured' indicates ongoing status but no bounded time period). The context is appropriately empty as no specific sense or role restriction applies. The quote is verbatim from the passage and directly supports the claim.
