+"""Concurrent-session MCP restart safety & dogfooding test suite (#666).
+
+Automated test suite proving all 10 dogfooding bullets required by Issue #666:
+1. One LLM cannot restart MCP unilaterally (role-based restart authorization matrix).
+2. New work stops during drain (assignments_stopped gate enforcement).
+3. Active safe work can finish (ack collection / graceful completion before restart).
+4. Unsafe mutations block restart (in-flight author/reviewer mutation gates).
+5. Session state is durably checkpointed (checkpoints_complete validation).
+6. Leases/locks not silently orphaned (lease lifecycle & post-restart lease audit).
+7. Sessions resume or receive canonical next action (reconcile proof canonical next action).
+8. Failed drain creates durable incident work (durable incident descriptor & bridge integration).
+9. Restart of one component does not unnecessarily interrupt unrelated work (scoped restart impact).
+10. Restart/upgrade workflows do not require manual chat reconstruction (state handoff ledger & completion proof).
