## Title

    [Claude Code] 'OAuth token has expired' / 'OAuth token revoked' in long-running or CLAUDE_CODE_OAUTH_TOKEN sessions

## Body

    Cause (Documented platform behavior): Saved or supplied OAuth token no longer valid; 'Invalid authentication credentials' means account/org revoked, not expiry.
    
    Fix status: documented_behavior (fixed in 2.1.225 (env token replacement bug))
    
    Misleading approaches:
    - /login when an approved ANTHROPIC_API_KEY is the active credential; it does not replace it
    
    Other error fragments:
    - Please run /login · API Error: 401 OAuth token has expired
    - Please run /login · API Error: 401 Invalid authentication credentials
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://code.claude.com/docs/en/errors (official_docs, 2026-09, documented_behavior): Docs distinguish revoked/expired OAuth token from 401 Invalid authentication credentials (account/org), and document the pre-2.1.225 CLAUDE_CODE_OAUTH_TOKEN replacement bug.
    
    Search phrasings: claude code oauth token expired ci; CLAUDE_CODE_OAUTH_TOKEN 401 expired; claude code 401 invalid authentication credentials
    
    Evidence basis (self-declared by the contributing chat client): public_source.
