Upstream attribution (required when redistributing derived data)
----------------------------------------------------------------
Sample and production data are derived from public sources that carry their
own attribution requirements. When you redistribute records derived from them,
preserve the `source` provenance on each record and credit:

  - PLATEAU (国土交通省 / MLIT Project PLATEAU) — building IDs and 3D city models.

  - Copernicus Emergency Management Service — Noto 2024 building damage data,
    where used. See https://emergency.copernicus.eu/ for terms.
  - Any dataset cited in a record's `source.dataset_id` / `source.url`.

The synthetic sample fixture shipped in `data/samples/` is generated by this
project (see data/samples/README.md) and is original CC BY 4.0 content; it is
NOT real Copernicus or PLATEAU data and must not be represented as such.
