# The programs inside must already carry a Developer ID signature with hardened runtime and secure
# timestamp: configure with -DJFJOCH_MACOS_SIGNING_IDENTITY=<certificate SHA-1> and let cpack produce
# the artefact (see the top-level CMakeLists.txt). The same certificate signs the .dmg here: the
# one JFJOCH_MACOS_SIGNING_IDENTITY names, else the Developer ID Application in the keychain. Needs
# notarytool credentials stored once on the machine, under the profile named by JFJOCH_NOTARY_PROFILE
# (default jfjoch-notary). On an unattended machine store them in the login keychain file: without
# --keychain they go into the data-protection keychain, which is unreadable while the screen is
# locked, and the step then fails with "No Keychain password item found".
#
#   xcrun notarytool store-credentials jfjoch-notary --apple-id <apple id> --team-id <team id> \
#       --keychain ~/Library/Keychains/login.keychain-db
#
# .dmg      signed with the same Developer ID, submitted, the ticket stapled to the image.
# .tar.gz   the rugnux binary inside is zipped and submitted; Apple then knows its hash, which is
#           all Gatekeeper needs (a bare executable has nowhere to staple a ticket). The archive is
#           shipped unchanged.
