## Title

    [Claude Code] 'API Error: Could not load AWS credentials · AWS default-chain credential resolve timed out' (Bedrock) from interactive credential_process or unreachable IMDS

## Body

    Cause (Documented platform behavior): Local AWS default credential chain doesn't resolve within 60s; before v2.1.207 the request hung indefinitely.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - Timed out after 60s waiting for AWS. Check your network and proxy settings; if a credential helper needs longer to prompt you, raise CLAUDE_CODE_AWS_CHAIN_RESOLVE_TIMEOUT_MS.
    - API Error: AWS default-chain credential resolve timed out
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://code.claude.com/docs/en/errors.md (official_docs, unknown, documented_behavior): Docs give exact messages, 60s limit, common causes (prompting credential_process, silent IMDS) and remedies, with version notes v2.1.207/v2.1.267.
    
    Search phrasings: claude code bedrock credential resolve timed out; claude code aws sso hang; CLAUDE_CODE_AWS_CHAIN_RESOLVE_TIMEOUT_MS
    
    Evidence basis (self-declared by the contributing chat client): public_source.
