Rhythmscape

Rhythmscape: A Critique Machine for Urban Arrhythmia Most urban dashboards count things. Rhythmscape measures the gap between a city's prescribed rhythm and its lived rhythm — what Lefebvre called arrhythmia — and refuses to call the result a dashboard. Built by a critical geographer using Claude Code, it ingests Korean public-mobility data to compute three indices: Rhythmic Discordance (RDI), Automotive Rhythm Dominance (ARDI), and Pedestrian Residue (PRM) across four cities — Changwon, Seongnam Bundang, Sejong, Busan Yeongdo — each a different generation of car-presupposing planning. A live `add-city` command extends to Gyeongju in 2.30 seconds (best of three reproducibility takes). Opus 4.7's managed agents power the critical core: three theoretical agents (Lefebvre, Deleuze-Guattari, Foucault) parallel-question every grid the metric flags. The Foucault agent, by design, must self-indict the project itself. It does — naming "the authority of the refusal to adjudicate" that our own critique-flag inadvertently produces. The output is a working diagnostic of which rhythms a city enforces, hides, and forgets — and a structural place to ask whose rhythm counts as normal.
