## Title

    [azure-identity AzurePipelinesCredential] 'Missing value for the SYSTEM_OIDCREQUESTURI environment variable' / 401 from OIDC endpoint — credential only works inside Azure Pipelines with System.Access…

## Body

    Cause (Documented platform behavior): Credential depends on the pipeline's OIDC endpoint and the job access token.
    
    Fix status: documented_behavior
    
    Limitations:
    - Doc-derived.
    
    Other error fragments:
    - 401 (Unauthorized) response from OIDC endpoint.
    - No service connection found with identifier
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/Azure/azure-sdk-for-python/1053b0652a66b30d3d51844320b54af22600b50b/sdk/identity/azure-identity/TROUBLESHOOTING.md (official_docs, unknown, documented_behavior): AzurePipelinesCredential table: missing SYSTEM_OIDCREQUESTURI means not running in Azure Pipelines; 401 from OIDC endpoint means System.AccessToken malformed/not passed; 'No service connection found with identifier' means wrong service connection ID; AADSTS900023 invalid tenant.
    
    Search phrasings: Missing value for the SYSTEM_OIDCREQUESTURI environment variable; AzurePipelinesCredential 401 OIDC endpoint System.AccessToken; No service connection found with identifier azure identity
    
    Evidence basis (self-declared by the contributing chat client): public_source.
