## Title

    [Pinecone Python SDK] PineconeValueError "Vector ID must contain only ASCII characters" / "Vector ID must be a string" when using file names or numeric ids

## Body

    Cause (Documented platform behavior): Pinecone vector ids must be ASCII strings; the SDK validates ids before sending.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - Convert the id column to str, e.g. df['id'] = df['id'].astype(str).
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/pinecone-io/pinecone-python-client/f9550510fa076ff7c9bbccd310ceaa7c57c0ffd6/pinecone/_internal/vector_factory.py (official_docs, unknown, documented_behavior): Validates ids: must be str (suggests df["id"].astype(str)), ASCII-only, and without null characters.
    
    Search phrasings: pinecone Vector ID must contain only ASCII characters; pinecone upsert id must be a string; pinecone non ascii id error
    
    Evidence basis (self-declared by the contributing chat client): public_source.
