maplibre-gl@5 and maplibre-gl-geocoder@1 were floating ranges, and no runtime loader set `integrity`,
so a CDN could serve any bytes to every partner's visitors unnoticed (CRITIC-5).
- library/constants/cdn.js is the one registry: mapbox-gl 3.24.0, maplibre-gl 5.24.0 (the release the
@5 range already resolved to), both geocoders (1.9.4 / 5.0.0) and d3 7.9.0, each with its sha384.
Every host answers Access-Control-Allow-Origin: *, so integrity + crossorigin work cross-origin.
- ensureEngineScript / ensureEngineCSS, the geocoder loaders (library and PPLR) and the generator's
static MapLibre tags set integrity + crossorigin from it; the embed snippet's engine preload matches.
- check:cdn-pins (gates:post): no floating CDN url in shipped code, and every one is in the registry;
--online re-fetches each and compares the hash (all 9 match today).
MapLibre stays on 5.x knowingly. GHSA-jrc7-96c5-q579 (DOM.sanitize, reached through a source's
attribution string) affects <= 6.4.0, and 6.x is ESM-only (no UMD global), so the upgrade is a loader
migration of its own. The attribution strings rendered today come from our configured basemap styles
and our own sources; the note in cdn.js says who is exposed until then.
