Improve tests to verify devDependency priority with different versions

- Use dead registry URL (http://localhost:9999/) to ensure tests fail if npm is contacted
- Test with different versions for dev and peer dependencies to catch incorrect resolution
- Use workspace:* protocol for devDependencies in tests
- Add version verification to ensure correct package version is used

These tests will now properly fail if the wrong dependency resolution occurs.

+# Upgrading Bun's Self-Reported Node.js Version
+
+This guide explains how to upgrade the Node.js version that Bun reports for compatibility with Node.js packages and native addons.
+
+## Overview
+
+Bun reports a Node.js version for compatibility with the Node.js ecosystem. This affects:
+- `process.version` output
+- Node-API (N-API) compatibility
+- Native addon ABI compatibility
+- V8 API compatibility for addons using V8 directly
+
+## Files That Always Need Updates
+
+### 1. Bootstrap Scripts
+- `scripts/bootstrap.sh` - Update `NODEJS_VERSION=`
+- `scripts/bootstrap.ps1` - Update `$NODEJS_VERSION =`
+
+### 2. CMake Configuration
+- `cmake/Options.cmake`
+  - `NODEJS_VERSION` - The Node.js version string (e.g., "24.3.0")
+  - `NODEJS_ABI_VERSION` - The ABI version number (find using command below)
+
+### 3. Version Strings
+- `src/bun.js/bindings/BunProcess.cpp`
+  - Update `Bun__versions_node` with the Node.js version
+  - Update `Bun__versions_v8` with the V8 version (find using command below)
+
+### 4. N-API Version
+- `src/napi/js_native_api.h`
+  - Update `NAPI_VERSION` define (check Node.js release notes)
+
+## Files That May Need Updates
+
+Only check these if the build fails or tests crash after updating version numbers:
+- V8 compatibility files in `src/bun.js/bindings/v8/` (if V8 API changed)
+- Test files (if Node.js requires newer C++ standard)
+
+## Quick Commands to Find Version Info
+
+```bash
+# Get latest Node.js version info
+curl -s https://nodejs.org/dist/index.json | jq '.[0]'
+
+# Get V8 version for a specific Node.js version (replace v24.3.0)
+curl -s https://nodejs.org/dist/v24.3.0/node-v24.3.0-headers.tar.gz | tar -xzO node-v24.3.0/include/node/node_version.h | grep V8_VERSION
+
+# Get ABI version for a specific Node.js version
+curl -s https://nodejs.org/dist/v24.3.0/node-v24.3.0-headers.tar.gz | tar -xzO node-v24.3.0/include/node/node_version.h | grep NODE_MODULE_VERSION
+
+# Or use the ABI registry
+curl -s https://raw.githubusercontent.com/nodejs/node/main/doc/abi_version_registry.json | jq '.NODE_MODULE_VERSION."<version>"'
+```
+
+## Update Process
+
+1. **Gather version info** using the commands above
+2. **Update the required files** listed in the sections above
+3. **Build and test**:
+   ```bash
+   bun bd
+   bun bd -e "console.log(process.version)"
+   bun bd -e "console.log(process.versions.v8)"
+   bun bd test test/v8/v8.test.ts
+   bun bd test test/napi/napi.test.ts
+   ```
+
+4. **Check for V8 API changes** only if build fails or tests crash:
+   - Compare v8-function-callback.h between versions
+   - Check v8-internal.h for Isolate size changes
+   - Look for new required APIs in build errors
+
+## If Build Fails or Tests Crash
+
+The V8 API rarely has breaking changes between minor Node.js versions. If you encounter issues:
+1. Check build errors for missing symbols or type mismatches
+2. Compare V8 headers between old and new Node.js versions
+3. Most issues can be resolved by implementing missing functions or adjusting structures
+
+## Testing Checklist
+
+- [ ] `process.version` returns correct version
+- [ ] `process.versions.v8` returns correct V8 version  
+- [ ] `process.config.variables.node_module_version` returns correct ABI
+- [ ] V8 tests pass
+- [ ] N-API tests pass
+
+## Notes
+
+- Most upgrades only require updating version numbers
+- Major V8 version changes (rare) may require API updates
+- The V8 shim implements only APIs used by common native addons

+- cd vendor/WebKit
+- git fetch upstream

-# How to build Bun
+### Build Commands
 
-Run:
+- **Build debug version**: `bun bd` or `bun run build:debug`
+  - Creates a debug build at `./build/debug/bun-debug`
+  - Compilation takes ~2.5 minutes
+- **Run tests with your debug build**: `bun bd test <test-file>`
+  - **CRITICAL**: Never use `bun test` directly - it won't include your changes
+- **Run any command with debug build**: `bun bd <command>`
 
-```bash
-bun bd
+### Run a file
+
+To run a file, use:
+
+```sh
+bun bd <file> <...args>
 ```
+
+**CRITICAL**: Never use `bun <file>` directly. It will not have your changes.
+
+### Logging
+
+`BUN_DEBUG_$(SCOPE)=1` enables debug logs for a specific debug log scope.
+
+Debug logs look like this:
+
+```zig
+const log = bun.Output.scoped(.${SCOPE}, false);
+
+// ...later
+log("MY DEBUG LOG", .{})
+```
+
+### Code Generation
+
+Code generation happens automatically as part of the build process. There are no commands to run.

-
-✅ Good
-
-```sh
-bun bd test internal/ban-words.test.ts
-bun bd ./foo.ts
-```
-
-The `bun bd` command runs the DEBUG build. If you forget to run the debug build, your changes will not be reflected..

-### Run a file
-
-To run a file, you can use the `bun bd <file-path>` command.
-
-```sh
-bun bd ./foo.ts

-
-### Run tests
-
-To run a single test, you need to use the `bun bd test <test-name>` command.
-
-```sh
-bun bd test internal/ban-words.test.ts
-```
-
-You must ALWAYS make sure to pass a file path to the `bun bd test <file-path>` command. DO NOT try to run ALL the tests at once unless you're in a specific subdirectory.

+This is the Bun repository - an all-in-one JavaScript runtime & toolkit designed for speed, with a bundler, test runner, and Node.js-compatible package manager. It's written primarily in Zig with C++ for JavaScriptCore integration, powered by WebKit's JavaScriptCore engine.
+
+## Building and Running Bun
+
+### Build Commands
+
+- **Build debug version**: `bun bd` or `bun run build:debug`
+  - Creates a debug build at `./build/debug/bun-debug`
+  - Compilation takes ~2.5 minutes
+- **Run tests with your debug build**: `bun bd test <test-file>`
+  - **CRITICAL**: Never use `bun test` directly - it won't include your changes
+- **Run any command with debug build**: `bun bd <command>`
+
+### Other Build Variants
+
+- `bun run build:release` - Release build
+
+Address sanitizer is enabled by default in debug builds of Bun.
+
+## Testing
+
+### Running Tests
+
+- **Single test file**: `bun bd test test/js/bun/http/serve.test.ts`
+- **Fuzzy match test file**: `bun bd test http/serve.test.ts`
+- **With filter**: `bun bd test test/js/bun/http/serve.test.ts -t "should handle"`
+
+### Test Organization
+
+- `test/js/bun/` - Bun-specific API tests (http, crypto, ffi, shell, etc.)
+- `test/js/node/` - Node.js compatibility tests
+- `test/js/web/` - Web API tests (fetch, WebSocket, streams, etc.)
+- `test/cli/` - CLI command tests (install, run, test, etc.)
+- `test/regression/issue/` - Regression tests (create one per bug fix)
+- `test/bundler/` - Bundler and transpiler tests
+- `test/integration/` - End-to-end integration tests
+- `test/napi/` - N-API compatibility tests
+- `test/v8/` - V8 C++ API compatibility tests
+
+### Writing Tests
+
+Tests use Bun's Jest-compatible test runner with proper test fixtures:
+
+```typescript
+import { test, expect } from "bun:test";
+import { bunEnv, bunExe, tempDirWithFiles } from "harness";
+
+test("my feature", async () => {
+  // Create temp directory with test files
+  const dir = tempDirWithFiles("test-prefix", {
+    "index.js": `console.log("hello");`,
+  });
+
+  // Spawn Bun process
+  await using proc = Bun.spawn({
+    cmd: [bunExe(), "index.js"],
+    env: bunEnv,
+    cwd: dir,
+  });
+
+  const [stdout, stderr, exitCode] = await Promise.all([
+    new Response(proc.stdout).text(),
+    new Response(proc.stderr).text(),
+    proc.exited,
+  ]);
+
+  expect(exitCode).toBe(0);
+  expect(stdout).toBe("hello\n");
+});
+```
+
+## Code Architecture
+
+### Language Structure
+
+- **Zig code** (`src/*.zig`): Core runtime, JavaScript bindings, package manager
+- **C++ code** (`src/bun.js/bindings/*.cpp`): JavaScriptCore bindings, Web APIs
+- **TypeScript** (`src/js/`): Built-in JavaScript modules with special syntax (see JavaScript Modules section)
+- **Generated code**: Many files are auto-generated from `.classes.ts` and other sources
+
+### Core Source Organization
+
+#### Runtime Core (`src/`)
+
+- `bun.zig` - Main entry point
+- `cli.zig` - CLI command orchestration
+- `js_parser.zig`, `js_lexer.zig`, `js_printer.zig` - JavaScript parsing/printing
+- `transpiler.zig` - Wrapper around js_parser with sourcemap support
+- `resolver/` - Module resolution system
+- `allocators/` - Custom memory allocators for performance
+
+#### JavaScript Runtime (`src/bun.js/`)
+
+- `bindings/` - C++ JavaScriptCore bindings
+  - Generated classes from `.classes.ts` files
+  - Manual bindings for complex APIs
+- `api/` - Bun-specific APIs
+  - `server.zig` - HTTP server implementation
+  - `FFI.zig` - Foreign Function Interface
+  - `crypto.zig` - Cryptographic operations
+  - `glob.zig` - File pattern matching
+- `node/` - Node.js compatibility layer
+  - Module implementations (fs, path, crypto, etc.)
+  - Process and Buffer APIs
+- `webcore/` - Web API implementations
+  - `fetch.zig` - Fetch API
+  - `streams.zig` - Web Streams
+  - `Blob.zig`, `Response.zig`, `Request.zig`
+- `event_loop/` - Event loop and task management
+
+#### Build Tools & Package Manager
+
+- `src/bundler/` - JavaScript bundler
+  - Advanced tree-shaking
+  - CSS processing
+  - HTML handling
+- `src/install/` - Package manager
+  - `lockfile/` - Lockfile handling
+  - `npm.zig` - npm registry client
+  - `lifecycle_script_runner.zig` - Package scripts
+
+#### Other Key Components
+
+- `src/shell/` - Cross-platform shell implementation
+- `src/css/` - CSS parser and processor
+- `src/http/` - HTTP client implementation
+  - `websocket_client/` - WebSocket client (including deflate support)
+- `src/sql/` - SQL database integrations
+- `src/bake/` - Server-side rendering framework
+
+### JavaScript Class Implementation (C++)
+
+When implementing JavaScript classes in C++:
+
+1. Create three classes if there's a public constructor:
+
+   - `class Foo : public JSC::JSDestructibleObject` (if has C++ fields)
+   - `class FooPrototype : public JSC::JSNonFinalObject`
+   - `class FooConstructor : public JSC::InternalFunction`
+
+2. Define properties using HashTableValue arrays
+3. Add iso subspaces for classes with C++ fields
+4. Cache structures in ZigGlobalObject
+
+## Development Workflow
+
+### Code Formatting
+
+- `bun run prettier` - Format JS/TS files
+- `bun run zig-format` - Format Zig files
+- `bun run clang-format` - Format C++ files
+
+### Watching for Changes
+
+- `bun run watch` - Incremental Zig compilation with error checking
+- `bun run watch-windows` - Windows-specific watch mode
+
+### Code Generation
+
+Code generation happens automatically as part of the build process. The main scripts are:
+
+- `src/codegen/generate-classes.ts` - Generates Zig & C++ bindings from `*.classes.ts` files
+- `src/codegen/generate-jssink.ts` - Generates stream-related classes
+- `src/codegen/bundle-modules.ts` - Bundles built-in modules like `node:fs`
+- `src/codegen/bundle-functions.ts` - Bundles global functions like `ReadableStream`
+
+In development, bundled modules can be reloaded without rebuilding Zig by running `bun run build`.
+
+## JavaScript Modules (`src/js/`)
+
+Built-in JavaScript modules use special syntax and are organized as:
+
+- `node/` - Node.js compatibility modules (`node:fs`, `node:path`, etc.)
+- `bun/` - Bun-specific modules (`bun:ffi`, `bun:sqlite`, etc.)
+- `thirdparty/` - NPM modules we replace (like `ws`)
+- `internal/` - Internal modules not exposed to users
+- `builtins/` - Core JavaScript builtins (streams, console, etc.)
+
+### Special Syntax in Built-in Modules
+
+1. **`$` prefix** - Access to private properties and JSC intrinsics:
+
+   ```js
+   const arr = $Array.from(...);  // Private global
+   map.$set(...);                 // Private method
+   const arr2 = $newArrayWithSize(5); // JSC intrinsic
+   ```
+
+2. **`require()`** - Must use string literals, resolved at compile time:
+
+   ```js
+   const fs = require("fs"); // Directly loads by numeric ID
+   ```
+
+3. **Debug helpers**:
+
+   - `$debug()` - Like console.log but stripped in release builds
+   - `$assert()` - Assertions stripped in release builds
+   - `if($debug) {}` - Check if debug env var is set
+
+4. **Platform detection**: `process.platform` and `process.arch` are inlined and dead-code eliminated
+
+5. **Export syntax**: Use `export default` which gets converted to a return statement:
+   ```js
+   export default {
+     readFile,
+     writeFile,
+   };
+   ```
+
+Note: These are NOT ES modules. The preprocessor converts `$` to `@` (JSC's actual syntax) and handles the special functions.
+
+## CI
+
+Bun uses BuildKite for CI. To get the status of a PR, you can use the following command:
+
+```bash
+bun ci
+```
+
+## Important Development Notes
+
+1. **Never use `bun test` or `bun <file>` directly** - always use `bun bd test` or `bun bd <command>`. `bun bd` compiles & runs the debug build.
+2. **Use `await using`** for proper resource cleanup with Bun APIs (Bun.spawn, Bun.serve, Bun.connect, etc.)
+3. **Follow existing code style** - check neighboring files for patterns
+4. **Create regression tests** in `test/regression/issue/` when fixing bugs
+5. **Use absolute paths** - Always use absolute paths in file operations
+6. **Avoid shell commands** - Don't use `find` or `grep` in tests; use Bun's Glob and built-in tools
+7. **Memory management** - In Zig code, be careful with allocators and use defer for cleanup
+8. **Cross-platform** - Test on macOS, Linux, and Windows when making platform-specific changes
+9. **Debug builds** - Use `BUN_DEBUG_QUIET_LOGS=1` to disable debug logging, or `BUN_DEBUG_<scope>=1` to enable specific scopes
+10. **Transpiled source** - Find transpiled files in `/tmp/bun-debug-src/` for debugging
+
+## Key APIs and Features
+
+### Bun-Specific APIs
+
+- **Bun.serve()** - High-performance HTTP server
+- **Bun.spawn()** - Process spawning with better performance than Node.js
+- **Bun.file()** - Fast file I/O operations
+- **Bun.write()** - Unified API for writing to files, stdout, etc.
+- **Bun.$ (Shell)** - Cross-platform shell scripting
+- **Bun.SQLite** - Native SQLite integration
+- **Bun.FFI** - Call native libraries from JavaScript
+- **Bun.Glob** - Fast file pattern matching

+Bun generally takes about 2.5 minutes to compile a debug build when there are Zig changes. If your development workflow is "change one line, save, rebuild", you will spend too much time waiting for the build to finish. Instead:
+
+- Batch up your changes
+- Ensure zls is running with incremental watching for LSP errors (if you use VSCode and install Zig and run `bun run build` once to download Zig, this should just work)
+- Prefer using the debugger ("CodeLLDB" in VSCode) to step through the code.
+- Use debug logs. `BUN_DEBUG_<scope>=1` will enable debug logging for the corresponding `Output.scoped(.<scope>, false)` logs. You can also set `BUN_DEBUG_QUIET_LOGS=1` to disable all debug logging that isn't explicitly enabled. To dump debug lgos into a file, `BUN_DEBUG=<path-to-file>.log`. Debug logs are aggressively removed in release builds.
+- src/js/\*\*.ts changes are pretty much instant to rebuild. C++ changes are a bit slower, but still much faster than the Zig code (Zig is one compilation unit, C++ is many).

-## Valgrind
+## AddressSanitizer
 
-On Linux, valgrind can help find memory issues.
+[AddressSanitizer](https://en.wikipedia.org/wiki/AddressSanitizer) helps find memory issues, and is enabled by default in debug builds of Bun on Linux and macOS. This includes the Zig code and all dependencies. It makes the Zig code take about 2x longer to build, if that's stopping you from being productive you can disable it by setting `-Denable_asan=$<IF:$<BOOL:${ENABLE_ASAN}>,true,false>` to `-Denable_asan=false` in the `cmake/targets/BuildBun.cmake` file, but generally we recommend batching your changes up between builds.
 
-Keep in mind:
-
-- JavaScriptCore doesn't support valgrind. It will report spurious errors.
-- Valgrind is slow
-- Mimalloc will sometimes cause spurious errors when debug build is enabled
-
-You'll need a very recent version of Valgrind due to DWARF 5 debug symbols. You may need to manually compile Valgrind instead of using it from your Linux package manager.
-
-`--fair-sched=try` is necessary if running multithreaded code in Bun (such as the bundler). Otherwise it will hang.
+To build a release build with Address Sanitizer, run:
 
 ```bash
-$ valgrind --fair-sched=try --track-origins=yes bun-debug <args>
+$ bun run build:release:asan
 ```
 
+In CI, we run our test suite with at least one target that is built with Address Sanitizer.

 ### HTML imports
 
-To add a client-side single-page app, you can use an HTML import:
+Bun supports importing HTML files directly into your server code, enabling full-stack applications with both server-side and client-side code. HTML imports work in two modes:
+
+**Development (`bun --hot`):** Assets are bundled on-demand at runtime, enabling hot module replacement (HMR) for a fast, iterative development experience. When you change your frontend code, the browser automatically updates without a full page reload.
+
+**Production (`bun build`):** When building with `bun build --target=bun`, the `import index from "./index.html"` statement resolves to a pre-built manifest object containing all bundled client assets. `Bun.serve` consumes this manifest to serve optimized assets with zero runtime bundling overhead. This is ideal for deploying to production.

 import myReactSinglePageApp from "./index.html";

When you import an HTML file in your server code, Bun automatically bundles all frontend assets (JavaScript, CSS, etc.) and embeds them into the executable. When Bun sees the HTML import on the server, it kicks off a frontend build process to bundle JavaScript, CSS, and other assets.

 - **Reducing HTTP requests.** A single package in `node_modules` may consist of hundreds of files, and large applications may have dozens of such dependencies.

 - **Code transforms.** Modern apps are commonly built with languages or tools like TypeScript, JSX, and CSS modules, all of which must be converted into plain JavaScript and CSS before they can be consumed by a browser. The bundler is the natural place to configure these transformations.

 2. **Lazy Evaluation**: The mock factory callback is only evaluated when the module is actually imported or required.
 
 3. **Path Resolution**: Bun automatically resolves the module specifier as though you were doing an import, supporting:
-
    - Relative paths (`'./module'`)
    - Absolute paths (`'/path/to/module'`)
    - Package names (`'lodash'`)
 
 4. **Import Timing Effects**:
-
    - When mocking before first import: No side effects from the original module occur
    - When mocking after import: The original module's side effects have already happened
    - For this reason, using `--preload` is recommended for mocks that need to prevent side effects

 ### Best Practices
 
 1. **Type Safety**
-
    - Please use strict types instead of `any` where possible
    - Leverage TypeScript's type system features (generics, unions, etc.)
    - Document complex types with JSDoc comments
 
 2. **Compatibility**
-
    - Use `Bun.__internal.UseLibDomIfAvailable<LibDomName extends string, OurType>` for types that might conflict with lib.dom.d.ts (see [`./fetch.d.ts`](./fetch.d.ts) for a real example)
    - `@types/node` often expects variables to always be defined (this was the biggest cause of most of the conflicts in the past!), so we use the `UseLibDomIfAvailable` type to make sure we don't overwrite `lib.dom.d.ts` but still provide Bun types while simultaneously declaring the variable exists (for Node to work) in the cases that we can.
