macOS ARM64 App Killed with SIGKILL - Gatekeeper Error -67062

Problem

ARM64 macOS app immediately killed with SIGKILL on launch. No crash report generated.

./myapp

zsh: killed ./myapp

Error Details System Logs:

kernel: (AppleSystemPolicy) ASP: Security policy would not allow process syspolicyd: MacOS error: -67062

Error Code: -67062 = errSecCSReqFailed (Code signature requirement failed)

Environment macOS 15.x (Sequoia) on Apple Silicon App signed with "Mac Developer" certificate Code signature is valid (verified with codesign -dvvv) All entitlements present, hardened runtime removed

Question How can I run a development-signed ARM64 app on macOS 15 without notarization?

Tried:

xattr -dr com.apple.quarantine app.app (didn't work)

spctl --add app.app (didn't work)

Re-signing with different entitlements (didn't work)

Gatekeeper still blocks with error -67062. Is there a way to bypass this for internal testing, or is Developer ID + notarization required even for development builds on macOS 15?
