**Note**: this is a very technical detail that you probably can **just skip**.

The `APIRouter`s are not "mounted", they are not isolated from the rest of the application.

This is because we want to include their *path operations* in the OpenAPI schema and the user interfaces.

## What is a Container { #what-is-a-container }

Containers (mainly Linux containers) are a very **lightweight** way to package applications including all their dependencies and necessary files while keeping them isolated from other containers (other applications or components) in the same system.

    expectedClosure.putEdge(N1, N3);
    expectedClosure.putEdge(N2, N2);
    expectedClosure.putEdge(N2, N3);
    expectedClosure.putEdge(N3, N3);
    expectedClosure.addNode(N4); // N4 is isolated => no incident edges in this transitive closure

    assertThat(
      transitiveClosure(undirectedGraph, ADD_SELF_LOOPS_FOR_CYCLES)).isEqualTo(expectedClosure);
  }

  @Test

        }
    }

    // ========== Helper Methods ==========

    private CIFSContext createFreshContext() {
        // Create a completely isolated context to avoid handle reuse issues on Linux Docker
        try {
            // Create a new context with fresh configuration each time
            // This ensures complete isolation between operations
