The live sitemap had 123. The local copy is gitignored, so it only updates when I build.

The header sent the literal text ${VAR} because the variable was only in my shell.

A one-line pnpm override did, and GitHub closed the alert.

Homebrew warned that the new one would never run by name, and which -a showed the shadowing.

Casting the column fixed it.

Git was running the installed copy from the main repo.

The fix was one line in the tsconfig that the component files actually resolve to.
