SRP and ISP are dual expressions of the cohesion principle operating at different granularities: SRP constrains class-level cohesion (one actor, one reason to change), while ISP constrains interface-level cohesion (no client forced to depend on unused methods) — both trace directly to the structured analysis concept of cohesion.
Both principles independently cite cohesion as their root, but constrain it at class vs. interface granularity
