Provenance Record

Well-structured, appropriately detailed technical news article. The five-step RL pipeline is explained clearly without over-simplifying. The 'Production Context and What We Don't Know' and 'Analysis' sections show editorial maturity by explicitly flagging open questions and contextualizing the commercial significance.

All 4 sources verified from disk snapshots (source-0.html.gz through source-3.html.gz, all status 200). Source-0 (Boston Dynamics engineering blog, bostondynamics.com): primary source, confirms all five pipeline steps, all direct quotes verbatim, robot specs (90 kg weight, two actuator types, infinite rotation, field-replaceable modules), and 'train in a day' aspiration. Source-1 (Interesting Engineering, interestingengineering.com): confirms 50-70 lb training range, 100+ lb real-world test, corroborates BD blog quotes. Source-2 (Tech Times, techtimes.com): confirms 56 degrees of freedom and 2.3-meter reach, Benjamin Stephens quote verbatim ('Put your whole body into it, was kind of the idea'), ~4 units/month production figure, Hyundai 30,000/year by 2028 target, Savannah Georgia RMAC, parts sequencing 2028 and component assembly 2030. Source-3 (Robotics and Automation News, roboticsandautomationnews.com): corroborates demo description and hardware design. All attributed quotes confirmed verbatim. The allowlist warning for bostondynamics.com and techtimes.com is a configuration gap, not a credibility issue — both are reputable sources (one is the company's own engineering blog).

All specific claims verified against sources: Alberto Rodriguez (Director of Robot Behavior), Shane Rozen-Levy and Vinay Kamidi (Research Engineers) confirmed in source-0 byline. Policy trained on 50-70 lb loads, successfully handled 100+ lb in testing confirmed in sources 1 and 2. 56 degrees of freedom and 2.3-meter reach confirmed in source-2. Benjamin Stephens title (Atlas Controls Associate Director) and quote confirmed in source-2. Four Atlas units/month production rate attributed to 'former employees' in source-2, correctly framed as approximate in the article. No hallucinations or fabrications detected across any claim.

High-quality submission. All sources verified, all quotes confirmed verbatim, all specifics traced to cited sources. APPROVE.
