Subagents become pluggable; sessions become portable
What this changes for operators
- Capability-profile assumption "subagents inherit approval mode" is now under-specified.
- Run-contract design should record which subagent protocol variant a run used.
- Adapter work should distinguish local from remote subagent execution.
- Session export/import gives operators a stable serialization point.
