Sierra closes conversations. Kai Resolve closes loops.
Sierra resolves the ticket. That's where the product ends. Kai Resolve investigates the issue and, if it's a confirmed bug, hands the context to Kai Code for plan mode, build mode, and a PR. The original customer gets notified when the fix ships.
