The city, companies, and AI answers
One pattern keeps returning in entity readings: a sentence from an About page survives a redesign and reappears in a ChatGPT answer, with a city detail that no longer applies. The Cartographie Calme blog starts from these small drifts: an outdated address, confusion between studio, practice, and integrator, thin evidence that the model reuses poorly. Notes appear when a pattern becomes dense enough to be useful.
