## Frequently asked questions

### Does a compliant budget prove a CDN cache hit?

No. Static directive calculations do not observe cache storage or provider overrides. Use actual response evidence and authorized configuration inspection.

### Does the browser tester reproduce a logged-in user's cookies?

Not automatically. Its current fetch setup offers no explicit cross-origin credentials mode, and browsers control restricted headers. Use an authorized external capture where needed.

### Is a generated HAR a network trace?

No. The cURL converter creates an offline request entry. It does not send the request, read referenced local files or capture a real response.

### Can rollback or a purge happen here?

No. These tools support review and evidence. The operator must deploy, invalidate or roll back through the appropriate system and retest.
