• Build failure during the 2026-07-07 “build all packages for x86_64” private-repo release pass. Source signature verification fails: unknown public key 9A9760894C8DA30D – different key from the 95FA6F43E21188C4 case (memory/arduino.md), same root cause class (see memory/TOOLING_NOTES.md’s GPG-key note and memory/HOST_INSTALL_POLICY.md for why importing it on the host is fine). Not imported/retried yet as part of this pass.
