- Around line 1-116: Add a package.json containing the ES module type to the
temporary fixture directory in namespace_class_names_match_node, before writing
the TypeScript fixtures, so Node resolves their import and export syntax as
modules.

Node.js v26.5.1 official documentation TypeScript type stripping default node file.ts

<source_evidence>
<source>
<title>Modules: TypeScript | Node.js v26.8.1 Documentation</title>
<location>https://nodejs.org/docs/latest-v26.x/api/typescript.html</location>
<excerpt>Modules: TypeScript | Node.js v26.8.1 Documentation ## Modules: TypeScript# History | Version | Changes | | --- | --- | | v26.0.0 | Removed`--experimental-transform-types` flag. | | v25.2.0, v24.12.0 | Type stripping is now stable. | | v24.3.0, v22.18.0 | Type stripping no longer emits an experimental warning. | | v23.6.0, v22.18.0 | Type stripping is enabled by default. | | v22.7.0 | Added`--experimental-transform-types` flag. | Stability: 2- Stable ### Enabling# There are two ways to enable runtime TypeScript support in Node.js: For full support of all of TypeScript&`#39`;s syntax and features, including using any version of TypeScript, use a third-party package. For lightweight support, you can use the built-in support for type stripping. ### Full TypeScript support# To use TypeScript with full support for all TypeScript features, including`tsconfig.json`, you can use a third-party package. These instructions use tsx as an example but there are many other similar libraries available. Install the package as a development dependency using whatever package manager you&`#39`;re using for your project. For example, with`npm`: ```bash npm install --save-dev tsx bashcopy ``` Then you can run your TypeScript code via: ```bash npx tsx your-file.ts bashcopy ``` Or alternatively, you can run with`node` via: ```bash node --import=tsx your-file.ts bashcopy ``` ### Type stripping# Added in: v22.6.0History | Version | Changes | | --- | --- | | v25.2.0, v24.12.0 | Type stripping is now stable. | By default Node.js will execute TypeScript files that contains only erasable TypeScript syntax. Node.js will replace TypeScript syntax with whitespace, and no type checking is performed. To disable this feature, use the flag--no-strip-types. Node.js ignores`tsconfig.json` files and therefore features that depend on settings within`tsconfig.json`, such as paths or converting newer JavaScript syntax to older standards, are intentionally unsupported. To get full TypeScript support, see Full TypeScript support. The type stripping feature is designed to be lightweight. By intentionally not supporting syntaxes that require JavaScript code generation, and by replacing inline types with whitespace, Node.js can run TypeScript code without the need for source maps. Type stripping is compatible with most versions of TypeScript but we recommend version 5.8 or newer with the following`tsconfig.json` settings: ```json { "compilerOptions": { "noEmit": true, // Optional - see note below "target": "esnext", "module": "nodenext", "rewriteRelativeImportExtensions": true, "erasableSyntaxOnly": true, "verbatimModuleSyntax": true } } jsoncopy ``` Use the`noEmit` option if you intend to only execute`*.ts` files, for example a build script. You won&`#39`;t need this flag if you intend to distribute`*.js` files. #### Determining module system# Node.js supports both CommonJS and ES Modules syntax in TypeScript files. Node.js will not convert from one module system to another; if you want your code to run as an ES module, you must use`import` and`export` syntax, and if you want your code to run as CommonJS you must use`require` and`module.exports`. - `.ts` files will have their module system determined the same way as .js files. To use`import` and`export` syntax, add`"type": "module"` to the nearest parent`package.json`. - `.mts` files will always be run as ES modules, similar to`.mjs` files. - `.cts` files will always be run as CommonJS modules, similar to`.cjs` files. - `.tsx` files are unsupported. As in JavaScript files, file extensions are mandatory in`import` statements and`import()` expressions:`import &`#39`;./file.ts&`#39`;`, not`import &`#39`;./file&`#39`;`. Because of backward compatibility, file extensions are also mandatory in`require()` calls:`require(&`#39`;./file.ts&`#39`;)`, not`require(&`#39`;./file&`#39`;)`, similar to how the`.cjs` extension is mandatory in…[truncated]</excerpt>

Add an ES module marker to the temporary fixture tree.
The fixtures use import and export, but the test does not create package.json. Node therefore treats the .ts files as CommonJS and can fail before producing the expected output. The pinned Node 26.5.1 runtime does support type stripping, but it does not change module-mode resolution.

Fixes #11259.
A class reexported through
import * as BSON+export *+export { BSON }currently reports its internal namespace lookup key as.name, including throughinstance.constructor.name. Imported class placeholders were registering consumer aliases and synthetic namespace keys over the source module's canonical display name.Skip display-name registration for imported placeholders, matching the existing ownership rule for class method registration. The defining module remains responsible for the name; namespace keys, class IDs, identity, and inheritance are preserved.
Validation (macOS arm64,
perry-dev, Node 26.5.1):Fresh unmodified-main compiler and runtime reproduce the original report and the expanded alias/namespace matrix; a standalone namespace-reexport control passes.
198 code-generation unit tests pass, including the two new LLVM-emission regressions that fail before the fix and the local-class display-name control.
All three native programs (original report, expanded matrix, standalone control) match Node byte-for-byte using the freshly rebuilt compiler and static runtime/stdlib archives from committed head
56a037b555, with caches and auto-optimization disabled.Formatting, diff whitespace, file-size, Node-version consistency, and test-registration checks pass.
The checked-in
namespace_class_namesCargo integration test passes (three separately compiled programs).No version bump. CI is still running. The lint job fails on public benchmark evidence freshness. The identical error reproduces on pristine base
1c8015cb6d; HEAD and base have the same benchmark input fingerprint (f6fc1c13f1b1578933fb3c96bfda57405bc37e04ce5c37612c6a0ca9d195ca92) and no Cargo.toml or benchmark changes. Regenerating unrelated benchmark evidence is outside this fix.Summary by CodeRabbit
