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 bc504d4a0a23 of https://github.com/maca/postgrest-admin-preview (zip prefix maca-postgrest-admin-preview-bc504d4/, America/Los_Angeles times): the zip is byte-identical to the one package.elm-lang.org recorded, SHA-1 2b88d927b2b9db8ec79d1974537504fcc7eb2695.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.
