Rerouted (regenerated, verified). Same repository and tag, but GitHub now builds the zip with different bytes, so it no longer matches the SHA-1 package.elm-lang.org recorded. The Lamdera package server serves a copy recovered from https://github.com/gribouille/elm-treeview.

What we checked: Tag 2.0.1 is still on github.com/gribouille/elm-treeview; its commit a72594097d9d is from 2019-11-07 13:48 UTC, before the version was published (2019-11-07 13:51 UTC); every file Elm uses matches a copy in a Lamdera package cache from 2021-02-13, from before the change; elm.json is byte-identical to package.elm-lang.org's; the exposed modules match docs.json; the zip's SHA-1 is not the published one (GitHub's zip no longer comes out byte for byte the same), so the contents were checked instead.

The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.
