## Title

    [Claude Code] TLS-inspecting proxy: 'Unable to connect to API: SSL certificate verification failed (UNABLE_TO_GET_ISSUER_CERT_LOCALLY)' / SELF_SIGNED_CERT_IN_CHAIN

## Body

    Cause (Documented platform behavior): Untrusted interception CA.
    
    Fix status: documented_behavior
    
    Misleading approaches:
    - NODE_TLS_REJECT_UNAUTHORIZED=0 disables validation entirely (docs say don't)
    
    Other error fragments:
    - Unable to connect to API: Self-signed certificate detected (SELF_SIGNED_CERT_IN_CHAIN)
    - Check your proxy or corporate SSL certificates
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://code.claude.com/docs/en/errors (official_docs, 2026-09, official_recommended_action): Docs quote both SSL messages and the /login variant, recommend NODE_EXTRA_CA_CERTS, and note no retries on cert failures since v2.1.199.
    
    Search phrasings: claude code corporate proxy ssl certificate; claude code NODE_EXTRA_CA_CERTS
    
    Evidence basis (self-declared by the contributing chat client): public_source.
