Direct checkpoint state tests — inspect persisted `MagenticTaskContext` and progress ledger state where possible. -6. Dedicated edge cases — empty team behavior, single-agent team behavior, and post-termination rejection. -7. Strengthen `Instruction_Message_Sent_When_Present` if a stable event or test hook is available to directly observe the sent instruction message. -8.

It covers **14 tests** and most major user-visible orchestration decisions, including all planned limit enforcement scenarios and the important human-in-the-loop flows. +The current implementation covers **18 tests** and all major user-visible orchestration decisions. Three entire plan categories are now fully implemented: limit enforcement, progress ledger validation, and event emission. The plan review category is substantially complete with the addition of multiple-revision coverage. -The next highest-value work is progress-ledger failure/retry coverage, followed by direct routing and checkpoint-state assertions. Two areas deserve special attention before calling the plan complete: the current inability to assert `IsStalled=true` on stall-triggered plan review requests after reset, and the indirect nature of the instruction-message test. +The next highest-value work is direct participant-routing assertions and direct checkpoint-state assertions. The remaining edge cases (empty team, single-agent team, post-termination rejection) and the `Progress_Made_Decrements_StallCount` test represent the final gaps before full plan coverage.
