This PR claims to fix issue #886 which is about restricting CORS middleware to localhost and Tauri origins for security. However, the only change in this PR is adding a comment to the README. The actual CORS configuration code in backend/main.py (lines 108-115) and sync-microservice/main.py (lines 32-38) still uses allow_origins=["*"], which allows any origin to access the API. This is a critical security vulnerability that contradicts the PR description.

According to the mentioned PR #886, the fix should include:

  1. Tightened CORS policy with an explicit whitelist of localhost and Tauri origins
  2. Restricted allowed methods and headers
  3. Extensive CORS middleware test suite
  4. Detailed CORS/security documentation

None of these changes are present in this PR.
