These items concern bugs and fixes around prompt-cache TTL values being incorrectly set or lost in MoA/auxiliary routes, Qwen routes emitting an unclamped 1-hour marker, and failover paths skipping re-preflight checks. The group is focused on correcting TTL handling across several agent and cache code paths.
