The Natural Earth and neighborhood packs were loaded with a JSON-attributed
import(). The Vite dev server answers that request with a JavaScript module,
which the browser rejects, so every analyst region scope failed and fell
through to a geocode lookup that could take 12-28 s.
- src/data/bundledJson.js fetches the pack from a new URL(..., import.meta.url)
asset in the browser; under Node the caller's attributed import runs.
- resolveRegionRingForQuery caps the geocode + admin-boundary rung at 3 s and
returns { error: 'region-timeout' }; the lookup keeps running and fills the
cache. The analyst query reports it as code 'region-timeout'. The Nepal
locator opts out of the budget.
- Unit tests for the loader, the timeout and the analyst error; the behavior
harness checks the Gulf of Mexico scope and retries Texas on region-timeout.
