Confirmed root cause via tccd's own log output: the hardened-runtime
hardened-runtime prompting policy checks for
com.apple.security.personal-information.addressbook (the Contacts
framework's TCC service is still internally named kTCCServiceAddressBook,
a holdover from the old AddressBook framework), not
com.apple.security.personal-information.contacts as the entitlements
file had. With the correct key, tccd allows the prompt and access is
now granted correctly on both macOS 27 beta and 26.5.1 stable — this
was never an OS bug, notarization requirement, or beta-only issue.
Also keeps the fuller CNError domain/code/userInfo logging added while
diagnosing this, in case Contacts TCC issues resurface.
