I am running into a persistent issue on my MacBook Pro 14″ M2 & iPad Pro running macOS Sequoia 15.1.
Whenever the machine encounters Cloud Key Vault security circle orphaned peer key desync, the following diagnostic log appears in Console:

secd: [SecurityCircle] Peer key 0x8343 unconfirmed by active Circle of Trust members

I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?
