## Title

    [Helicone proxy] Helicone-RateLimit-Policy rejected: "Invalid policy format. Expected \"[quota];w=[window]\" ..." / "Window must be at least 60 seconds"

## Body

    Cause (Documented platform behavior): Policy must match [quota];w=[seconds](;u=request|cents)(;s=segment) with 60 <= window <= 31536000 and positive quota.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - Window must be at least 60 seconds
    - Quota must be a positive number
    - Window cannot exceed 31536000 seconds (1 year)
    
    Evidence (public sources, summarized; not reproduced by this contributor):

    Search phrasings: helicone rate limit policy invalid format; Helicone-RateLimit-Policy window must be at least 60 seconds
