------------------------------------------------------------------------------
Independence statement
------------------------------------------------------------------------------
nearmiss is an independent, personal open-source project. It is not affiliated
with, sponsored by, or endorsed by any employer, client, city, or public
agency. It contains no proprietary or client material. It is a community-owned
evidence base for safe-streets advocacy — not a municipal 311 queue and not a
complaint inbox for any public-works department.

------------------------------------------------------------------------------
Data, privacy, and honesty
------------------------------------------------------------------------------
Precise raw reports are private and are never published or committed to version
control. The published open dataset is aggregated to public street segments,
with low-count segments withheld (k-anonymity) to protect contributor privacy
(see docs/THREAT-MODEL.md and docs/DATA-CARD.md). Every
published risk figure is exposure-normalized and carries a confidence interval;
the reporting bias of the dataset is named, not hidden (see docs/METHODOLOGY.md).

------------------------------------------------------------------------------
Third-party components
------------------------------------------------------------------------------
Leaflet (https://leafletjs.com), (c) 2010-2023 Vladimir Agafonkin and Leaflet
contributors, is vendored under web/vendor/leaflet/ for the interactive map. It
is licensed under the BSD 2-Clause License. The unmodified upstream distribution
(v1.9.4) is included so the site has no third-party code CDN dependency.

Map tiles displayed by the web UI are served by OpenStreetMap
(https://www.openstreetmap.org/copyright); map data (c) OpenStreetMap
contributors, available under the Open Database License (ODbL). Tiles are
requested by the visitor's browser at runtime and are attributed in the UI.

The real-data bridge (tools/fetch_bikemaps.py) reads public reports from
BikeMaps.org (https://bikemaps.org, SPARLab/BikeMaps). BikeMaps data is the
property of its contributors and the BikeMaps project; consult BikeMaps.org for
its terms before redistributing data derived from it.

The SimRa bridge (tools/fetch_simra.py) reads the openly published SimRa dataset
(TU Berlin, https://github.com/simra-project/dataset). SimRa data is licensed
CC BY-NC 4.0 (https://creativecommons.org/licenses/by-nc/4.0/), with an
additional grant from the project for journalistic use, and is subject to the
terms of use in that repository. The NonCommercial condition is a real
constraint and does not disappear when the data is aggregated: a published
dataset assembled from SimRa reports carries it, and such a dataset is therefore
not distributable under Apache-2.0 alone. No SimRa-derived data is currently
committed to or published from this repository; the adapter is a local ingestion
path only.

Incident source adapters generally (src/nearmiss/adapters/) read third-party
datasets that retain their own licenses and terms. Each source's license is
recorded in its crosswalk manifest under src/nearmiss/adapters/crosswalks/.
Apache-2.0 covers this project's code, schema, and methods; it does not and
cannot relicense someone else's data. Check the manifest before redistributing
anything derived from a source.
