 ## Phase 2: Infrastructure Verification
-- [ ] Task: Write tests for `.\scripts
-un_subagent.ps1` to ensure it correctly spawns stateless agents and handles output.
-- [ ] Task: Verify `run_subagent.ps1` behavior for Tier 3 (coding) and Tier 4 (QA) use cases.
-- [ ] Task: Create a diagnostic test to verify Tier 2 -> Tier 3 delegation flow and context isolation.
