Research direction

Start with InsecureAndroidTrustManager.kt and read checkServerTrusted() to understand when it returns an empty certificate list. Then look for tests covering this trust-manager behavior; done means the insecure-host path no longer permits the MITM-enabling behavior described in the issue.

Written by the indexing model from the issue text.

Description

bug

checkServerTrusted() returns an empty list of certificates if the host is insecure, which allows for MITM.
