banshee-data/velocity.report — reverse-engineered prompt

Build me a local first street speed reporting app for neighborhood groups and researchers. I want something that takes data from radar and LiDAR sensors, measures how fast traffic is moving, and turns it into clear reports people can actually use in meetings or planning submissions. The big idea is privacy. It should measure velocity and movement without collecting identity, so no cameras, no plates, no faces, and no personal data by design.

It should run on a local device, ideally something small like a Raspberry Pi, and work offline first. If maps or other outside data are needed, make that an explicit opt in. I want PDF reports with speed distributions, percentile stats, and before and after comparisons for traffic calming projects. It should also support raw local data analysis and object level tracking and classification from LiDAR in a transparent, auditable way.

Please keep it clearly marked as alpha and safe for private network use only, not for the open internet. Look up current docs online if you need to.
