EDITORIAL STANDARD
Specifications, pricing, availability and release details trace back to vendor documentation whenever a primary source exists.
Directly comparable facts stay separate from vendor benchmarks, launch claims and interpretation.
Guides answer practical questions: what changed, what it costs, what it is built for and where tradeoffs appear.
Guides connect to Models, Topics and Signals so new developments update context instead of becoming isolated posts.
