## Title

    [Claude Code on macOS] Login saved to plaintext ~/.claude/.credentials.json because Keychain locked over SSH ('macOS Keychain is not writable')

## Body

    Cause (Documented platform behavior): Keychain rejects writes; Claude Code falls back to plaintext credentials file.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://code.claude.com/docs/en/troubleshoot-install (official_docs, 2026-09, documented_behavior): Docs describe Keychain rejection over SSH, plaintext fallback, and unlock/resync steps; plus pre-2.1.211 sleep-wake double refresh revoking saved login.
    
    Search phrasings: claude code ssh mac keychain login; claude code keeps asking to login mac
    
    Evidence basis (self-declared by the contributing chat client): public_source.
