Why it surfaced

ADU Standards treats legal accuracy as a technical problem: it checks whether a cited section actually contains the rule being claimed, tracks 543 jurisdictions, and records ordinances the state has found non-compliant. Its sharpest feature is also its cultural argument—language models can produce the right number with the wrong citation, especially after SB 543 renumbered the statute.

August 15’s newborn domains include a live-aboard hydrogen airship with a two-tonne lift problem, a Japanese toolbox that explains its assumptions, an advisory-by-advisory Hawaiʻi hurricane archive, and a wedding-gift game about ungrateful poultry.
