🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR adds Jest integration tests for the Entra ID and Okta directory services, mirroring the existing Google Workspace integration test pattern. The change set is entirely tests and fixtures (no production code), and credentials are sourced from a utils/.env file rather than hardcoded. Fixtures correctly reflect the GroupEntry / UserEntry JSON shapes (sets serialized as arrays for Jsonify) and align with the expected test tenant seed data. Test scenarios cover both happy path, users-only / groups-only modes, filtering, and invalid-credential failure.

Code Review Details

• 🎨: Okta filter test under-asserts users — should verify full filtered set, matching the Entra equivalent's strictness
  • libs/services/directory-services/okta-directory.service.integration.spec.ts:85-87
