1. A sleeve system, comprising:
a plug;
a housing having a plurality of first ports, each extending from an inner diameter to an outer diameter of the housing;
a sleeve slidably disposed within the housing and configured to transition between:
a first position, in which the sleeve occludes the first ports and a proximal end of the sleeve is positioned axially above the first ports; and
a second position, in which the sleeve exposes the first ports and defines an annular volume between the plug and the housing, the annular volume being radially aligned with the plug;
wherein, in the second position:
a channel provides fluid communication from a location above a proximal end of the plug to the first ports,
the channel extends from the proximal end of the plug to one or more windows disposed within the plug, and
fluid flow is enabled through the channel and the first ports;
wherein movement of the sleeve from the first position to the second position is initiated by hydraulic pressure applied to the plug;
wherein, in the second position, the proximal ends of both the plug and the sleeve are positioned above an uppermost extent of the first ports;
and wherein an object is disposed within the channel, the object being configured to temporarily obstruct fluid flow through the channel, such that upon removal or degradation of the object, fluid is permitted to flow through the channel and out the first ports.
