Edge cases: empty team, dedicated single-agent team, post-termination rejection ## Overall Conclusion -The current implementation should be considered a correct and valuable partial completion of the original plan. It covers the most important user-visible orchestration paths and validates the previously missing output declaration in production code. The remaining work is well-scoped and can continue incrementally, with priority given to progress-ledger failure/retry handling and reset-limit coverage. +The current implementation covers 14 of the ~31 originally planned tests and should be considered a correct and valuable implementation covering all major orchestrator decision paths. It validates the previously missing output declaration in production code, covers all three limit enforcement branches, and exercises the most complex orchestrator flows including stall-triggered replanning with plan signoff. The remaining work is well-scoped and can continue incrementally, with priority given to progress-ledger failure/retry handling.
