Summary

What — Makes the edited-dates step of the docs yarn prep script work on Windows by removing a POSIX-only shell command and normalizing the project path before comparing it with git's output.

Why — generateEditedDates ran { git diff --name-only ; git diff --name-only --staged ; } | sort | uniq through child_process.exec. On Windows, exec uses cmd.exe, which can't parse { ...; } grouping, so prep crashed for Windows contributors. Even with the command fixed, monorepoRelativePath came from string replacement on an OS path. On Windows it kept backslashes (and a leading \), so it never matched git's forward-slash paths, and changed pages would have been silently skipped.

How — In www/packages/build-scripts/src/generate-edited-dates.ts:

• monorepoRelativePath is now path.relative(rootPath, projectBasePath) with separators normalized to /.
• getChangedFiles runs git diff --name-only and git diff --name-only --staged as separate commands, then merges and dedupes the output with a Set instead of sort | uniq.

tsconfig.json now excludes __tests__ from the build, the same way docs-utils does, so tsc doesn't compile the test.

Testing — Added www/packages/build-scripts/src/__tests__/generate-edited-dates.test.ts. It mocks exec to behave like a shell that only accepts plain commands, mocks fs, and runs under both path.posix and path.win32. It checks that unstaged and staged pages of the project are collected and deduped, and that pages of other projects are left out.

• Before the fix, both cases failed with '{ git diff --name-only ; git diff --name-only --staged ; } | sort | uniq' is not recognized as a command.
• With only the command fixed, the win32 case still failed: it received [] instead of the three changed pages.
• After the full fix, both cases pass.

Additional Context

• No changeset: build-scripts is a private www/ package and isn't published.
• build-scripts has no test script, and the www workspace dependencies weren't installed in this environment. I ran the test with the root vitest binary and a minimal throwaway config (environment: "node", inline esbuild tsconfig), because www/vitest.config.mts needs plugins that aren't installed.
• Not fixed here: on Windows, getAllProjectFiles and the untracked-files branch build keys with path.relative, which gives backslash-separated keys. Also, file.startsWith(monorepoRelativePath) would match a sibling project whose name starts with the same prefix (e.g. www/apps/book-foo).

Thanks for the contribution! Initial automated review looks good.

Verdict: Looks good for a final review by the team.

Fixes the generateEditedDates build step on Windows by splitting the POSIX-only shell-grouped git diff command into two separate promiseExec calls deduped with a Set, and by normalizing the monorepoRelativePath to forward slashes via path.relative + .split(path.sep).join("/").

Checked: security (no user input reaches the shell commands), correctness (empty-string entries are filtered by startsWith; dedup is sound), performance, conventions, tests (posix and win32 cases both covered).
