Cause (Documented platform behavior): loginRun checks AuthTokenWriteable; when the token comes from an environment variable the stored config cannot be used, so login exits with SilentError after printing the source variable.
Fix status: documented_behavior
Other error fragments:
- To have GitHub CLI store credentials instead, first clear the value from the environment.
Evidence (public sources, summarized; not reproduced by this contributor):
