The lede fatality claim is now supported by [^2] and [^4] alone, both of which confirm multiple deaths. The Nippon Dynawave / Longview location is supported by [^3][^5][^6]. The "at least 10 injured" figure is supported by [^6][^8]. Chemical burns treatment is supported by [^1] and [^6]. Missing persons claim is supported by [^8]. The public safety/Industrial Way advisory is supported by [^5]. The liquid hazmat tank identification is supported by [^5]. All key facts trace to snippets that support them. No fabricated quotes, no unsupported claims, no single-source saturation.
