Running full test suites across 140+ tenant domain views for every single minor commit degrades developer velocity. A **Topological Dependency Graph Service** parses Abstract Syntax Trees (AST) to map exact component dependencies, testing exclusively the modified domain and its affected dependents while guaranteeing zero regressions.
1. Topological Blast Radius Calculation
When a shared component (e.g. `src/views/_shared/Head.tsx`) is modified, the topological graph traverses all parent import edges, automatically queuing snapshot validations across affected domains while skipping untouched isolated views.
