MeshCore Canada region data notice
==================================

canada-regions.json
-------------------

This file implements the Canada MeshCore Region Strategy v1.1.1. It also
credits Adam Gessaman's Pacific Northwest MeshCore region tools as an
inspiration:

MCC-REG-1 authority sources
---------------------------

The region definition and authority standard specifies Statistics Canada 2021
Dissemination Areas as the topology units, 2021 Census Subdivisions as the
indivisible-by-default municipal or municipal-equivalent cohorts, 2021 Census
Divisions as higher regional cohorts, and 2021 Economic Regions as broad
generation guardrails. canada-region-membership.csv and
canada-region-partition.geojson are derived from those sources. The original
Statistics Canada shapefiles are not redistributed. sources.lock.json records
the exact downloads, byte sizes, dates, licences, and SHA-256 hashes used to
generate the committed candidate layer.

municipal-overrides.json records reviewed CD/CSD ownership decisions and any
approved CSD split. A split must enumerate every affected Dissemination Area;
an editor export or draft is not authoritative until reviewed and merged.

Cross-province entries in canada-regions.json are non-geographic repeater
configuration metadata. They join canonical member paths in generated commands
without changing DA ownership or creating another boundary layer.

Neighbouring U.S. entries are also non-geographic configuration metadata. They
are optional, never selected from a map point, and never add U.S. geometry to
the Canadian layer. Documented path names come from:

https://wnymeshcore.org/guides/radio-settings
https://gessaman.com/meshcore/regions/
https://www.regionmesh.com/meshcore-region-configuration/

Their 2026-07-18 trafficEvidence fields contain aggregate resolved-route
pattern and observation counts from:

https://dev.meshcore.ca/

Only areas with observed Canada-U.S. routes are listed. The catalog retains no
node identifiers, names, or exact coordinates. A route count supports review
of an optional forwarding path; it is not a coverage guarantee or a boundary
source.

radio-density.json
------------------

This file is a privacy-safe aggregate snapshot derived from the MeshCore Canada
live and development node directories:

https://live.meshcore.ca/
https://dev.meshcore.ca/

It is secondary evidence for close whole-CSD decisions only. It joins fresh
positioned live observations with the current positioned dev directory, but
uses dev-only records for advisory density because that endpoint has no
per-node timestamp. Published geographic and candidate counts are at least five,
candidate evidence is specific to its CSD, and clusters have a maximum 30 km
diameter. Raw node identifiers, names, and exact coordinates are not persisted.
The source-response hashes and fetch statistics provide audit evidence without
redistributing source records.
