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/webbhuset/elm-json-decode.
What we checked: Tag 1.0.0 is still on github.com/webbhuset/elm-json-decode; its commit b8aec69576cf is from 2018-11-07 09:00 UTC, before the version was published (2018-11-07 09:00 UTC); 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.
