77 ecosystem, which must become a mandatory interface for all special representatives [4]. This will allow:  Unification of requirements for project documentation;  Ensuring transparency in resource allocation in real-time;  Minimizing information asymmetry, as emphasized by O. Williamson in the theory of governance mechanisms [11]. Furthermore, it is advisable to implement a "sectoral leadership" model where, by decision of the Multi-agency Platform, one special representative (or group) leads the coordination of a specific sector (e.g., energy – USA, transport – EU, ports – Great Britain), thereby eliminating functional overlap of mandates. Conclusions. The coordination mechanisms for the activities of special representatives require a transformation from a "parallel offices" model to an "integrated network" model. Destructive complementarity, fueled by donor competition and blurred procedures, is a serious challenge to Ukraine's state capacity. Strengthening the role of national coordination centers, the legal formalization of the status of international representatives, and the mandatory use of digital monitoring systems are necessary steps to ensure that international assistance becomes an additive factor in recovery rather than a source of administrative chaos.
