What
Git commands run inside cloud sessions now automatically inject GIT_CONFIG_KEY_N=credential.interactive / GIT_CONFIG_VALUE_N=false via the GIT_CONFIG_COUNT mechanism. This prevents git from hanging waiting for interactive credential input when cloning or fetching in a headless cloud environment.
Evidence
Git env helper (search for "credential.interactive") — kF() function at line ~223497
