Field notes
The sample workflow lets users describe a café format, customers, and price point, then fine-tune signal weights. Its example ranks 58 blocks for a commuter coffee bar and breaks out contributions such as office workers and transit access. Coverage is bounded: Manhattan results are organized into four study areas, while Soho, London is marked experimental and unvalidated.
