# Release builds (docs/releasing.md), after SolidCraft's and VectorCraft's release.yml
# (MIT OR Apache-2.0; see ATTRIBUTION.md).
#
# A push to `main` (fast-forwarded from a verified `develop` commit; main holds released code only)
# builds every package and creates or updates the
# DRAFT GitHub Release "FieldCraft v<version>", with SHA256SUMS.txt (signed with the release key
# into SHA256SUMS.txt.minisig when the FIELDCRAFT_SIGNING_KEY secret exists) and generated notes. The
# version is [workspace.package] version in Cargo.toml; a suffix (0.2.0-rc.1) makes a
# pre-release. A person verifies the draft and publishes it; this workflow never publishes,
# and pushes to develop or tags never start it.
#
#   macOS universal (arm64 + x86_64)   .dmg with FieldCraft.app, the CLI as a .zip   packaging/macos
#   Linux x86_64 (glibc 2.35+)         .tar.gz, .AppImage, .deb and .rpm              packaging/linux

# macOS: signed with a Developer ID and notarized when the APPLE_* secrets exist, ad-hoc
# otherwise (the release notes say which). Linux and Windows builds are not signed.
#
# Dry run: `gh workflow run release.yml --ref <branch>` builds everything and uploads the
# `release-assets` artifact without creating a release. `-f draft=true` on `main` retries
# the draft.
