To prevent pipeline hangs, the uploader implements a timeout mechanism for these network requests. There is uncertainty regarding the behavior of the Version Control System (VCS) status check when a timeout occurs during the upload phase. Sp

When network latency occurs or the report size is exceptionally large, the uploader may encounter a timeout during the transmission phase. By default, a failed upload results in a non-zero exit code, which triggers a build failure in the pipeline. Whi

In practice, the cache key is derived from the repository, branch, and commit hash, but the exact trigger for cache invalidation is not documented. This creates uncertainty for CI p
