Hey @jakebailey, the results of running the DT tests are ready.

Everything looks the same!

You can check the log here.

@jakebailey Here are the results of running the user tests with tsc comparing main and refs/pull/62726/merge:

There were infrastructure failures potentially unrelated to your change:

1 instance of "Git clone failed"

Otherwise...

Everything looks good!

Pull request overview

This pull request updates the TypeScript compiler to always set up a module resolver host in the node builder, which changes how module specifiers are represented in symbol baselines from absolute or normalized paths to their original relative import paths (e.g., from "0" to "./0", or from "/node_modules/foo/index" to "foo").

Changes:

Modified the node builder context creation logic to always provide a module resolver host
Updated all test baselines to reflect the new module specifier representation in symbol files

Reviewed changes

Copilot reviewed 300 out of 794 changed files in this pull request and generated no comments.

File	Description
src/compiler/checker.ts	Simplified module resolver host initialization to always use a basic node builder module specifier resolution host
tests/baselines/reference/*.symbols	Updated symbol baselines to use original relative import paths instead of normalized paths
tests/baselines/reference/*.types	Updated type baselines to use original relative import paths instead of normalized paths
tests/baselines/reference/*.baseline.jsonc	Updated JSON baselines to use original relative import paths instead of normalized paths
