Did not apply the patch. It set a global dispatcher on the npm undici package and rewrote the lockfile. Node's built-in fetch does not use that dispatcher, and node:undici is not importable. fetch() reads HTTP_PROXY, HTTPS_PROXY and NO_PROXY only at startup, and only when that startup had NODE_USE_ENV_PROXY=1 (or --use-env-proxy). That is Node >=22.21.0 and >=24.0.0.
tools/fetch-assets.mjs restarts itself once with NODE_USE_ENV_PROXY=1 before downloading. The default fetch in the downloader and the index cache rejects when a proxy is set but this process cannot use it, including Node 22.0–22.20 and 23, instead of fetching directly. No new dependency. Engines stay >=22.
Tests: node --test test/assets-env-proxy.test.js — 8 pass, 0 fail. node --test test/asset-network.test.js test/assets-diy.test.js test/fetch-assets-shrink.test.js test/assets.test.js — 84 pass, 0 fail. Before this commit: npm run -s lint — 0 errors (135 existing warnings); npm run -s typecheck — ok; npm run -s check:imports — exit 0 (3 pre-existing sim-node notes). docs, version and package tests: 46 pass and 1 fail while env-proxy.mjs was still untracked; after git add, node --test test/package.test.js — 10 pass, 0 fail.
