Engineering notes
Four pieces in preparation — the full write-ups land with the beta. The short versions are already true.
The original idea read parking lots from satellite snapshots. It demoed well and failed quietly in the real world — here's what broke, and why real map geometry won.
Principal axis via PCA, area with the shoelace formula, ray-casting to fill the shape with Italian-standard stalls. Triangular lot in, triangular lot out.
Eight hourly occupancy curves, capacity math, distance weighting and user feedback — the exact model you can poke at on the home page.
When the deterministic model isn't enough, the candidates go to Claude with full context. How the handoff works, what it costs, and why it always falls back gracefully.
