 Keep `ExternalsLoadingPlugin` focused on consuming finalized `externals` maps and generating runtime loading code. Do not bake project-specific preset expansion or filesystem-backed dev serving into this low-level plugin; those concerns belong in higher-level Rsbuild integrations such as `pluginExternalBundle`. It is acceptable for this low-level plugin to resolve a relative `bundlePath` against the runtime `publicPath`, because that stays within generic bundler/runtime behavior instead of Rspeedy-specific URL inference.
+When migrating this package's config-case tests to `@rspack/test-tools`, preserve the existing two-bundle coverage by using `test/configCases/**` with `test.config.js` files whose `findBundle()` returns both emitted entry bundles, typically `['main:main-thread.js', 'main:background.js']`, instead of collapsing coverage to a single bundle.

 When migrating webpack package tests from Vitest to Rstest, define `setupFiles` in `rstest.config.ts` via `createRequire(import.meta.url).resolve(...)` instead of bare package subpaths to avoid module resolution issues.
+When migrating webpack package config cases from `test/**/cases/**` to `test/**/configCases/**`, keep root ESLint ignores aligned so config-case fixtures continue to be treated like other harness-owned case files instead of suddenly failing generic `no-undef` and `import/no-unresolved` rules.
 For ESM case config files (`*.config.js` under package tests), prefer explicit ESM-safe imports (for example `../../../../lib/index.js`) and use `createRequire(import.meta.url)` plus `new URL('.', import.meta.url).pathname` when `require.resolve` or `__dirname` behavior is needed.
 If hot-snapshot cases report incomplete update steps after migration, run targeted snapshot refresh with `rstest -u` on the specific `HotSnapshot.test` filter before broad reruns.
 When shared `@lynx-js/test-tools` helpers are migrated to read test APIs from `globalThis`, keep `globals: true` in Vitest configs for still-Vitest suites that consume those helpers (for example webpack react/css-extract plugin suites).
