Dataset release v0.5.2-evidence-gaps-closed
Closed the four documented provenance gaps left open in 0.5.1 with dated, live-verified public sources: the 2022 supply-chain event (White House AM Forward fact sheet and CEA analysis, SME Manufacturing Engineering), the 2022 workforce-development event (AM Forward workforce commitments, Manufacturing USA listing of SME's CAMT credential, SME SkillsUSA certification exams, 2022 Manufacturing USA Highlights), the 2023 lifecycle-assessment event (Kokare et al. 77-study LCA review plus three 2023 open-access MDPI Sustainability studies), and the present materials-expansion signal (NASA GRX-810 licensing, NASA RAMPT/GRCop-42, America Makes PADAM refractory C-103 awards, DOE/ORNL tungsten review, NASA RAMFIRE aluminum). Each record now carries a research_note stating exactly which portion of the claim the refs do not cover; claim text is unchanged.
