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/maca/postgrest-admin-preview.
What we checked: Rebuilt with git archive from commit abd96fc50f6f of https://github.com/maca/postgrest-admin-preview (zip prefix maca-postgrest-admin-preview-abd96fc/, America/Los_Angeles times): the zip is byte-identical to the one package.elm-lang.org recorded, SHA-1 55c7977c81a9d2cb2275a477cfd5ad84fb82bb8c.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.
