SRP and ISP's dual expression of cohesion (class-level responsibility and interface-level role segregation) enriches SOLID's mutual reinforcement by ensuring the principle system addresses granularity at both the implementation unit and the client-facing contract, preventing responsibility diffusion at either boundary.
Cohesion at two granularities strengthens the reinforcement loop — modules AND their interfaces resist responsibility creep
