# Hash Bags macOS build: signed with Developer ID, notarized, stapled.
#
# This is DIRECT distribution, not the Mac App Store, so it needs a
# "Developer ID Application" certificate. That is a different certificate from
# the "Apple Distribution" one build-ios-testflight.yml uses, and the two are
# not interchangeable: a build signed with the App Store cert is rejected by
# Gatekeeper when a user downloads it from a web page. Notarization, on the
# other hand, reuses the App Store Connect API key that repository already has.
#
# Secrets, all optional. Absent ones do not fail the build; they downgrade it,
# loudly, and the preflight below prints exactly which stage you will lose.
#   APPLE_CERTIFICATE            base64 of the Developer ID Application .p12
#   APPLE_CERTIFICATE_PASSWORD   password set when the .p12 was exported
#   APPLE_SIGNING_IDENTITY       "Developer ID Application: Such Software LLC (D8PL9F7X33)"
#   APPLE_TEAM_ID                D8PL9F7X33
#   APPLE_KEYCHAIN_PASSWORD      any value; scopes a throwaway keychain
#   APPLE_API_KEY_P8_BASE64      base64 of AuthKey_<id>.p8   (notarization)
#   APPLE_API_KEY                key id                      (notarization)
#   APPLE_API_ISSUER             issuer UUID                 (notarization)
#   GH_RELEASE_TOKEN             publishes the zip to the GitHub release
#
# The same names smirk-monorepo uses, deliberately: both repositories live under
# the Builds owner, so an organisation-level secret serves both and a reader
# comparing the two workflows is not left wondering whether the difference means
# something.
