      description: 'Get latency distribution with percentiles (p1, p5, p10, p25, p50, p75, p90, p95, p99)

        aggregated by day and model.


        Returns latency percentiles for:

        - proxy_latency: Time from request received to upstream call initiated

        - ttft_latency: Time from upstream call to first byte received (Time To First Token)


        Defaults to the caller''s own data. Admin users (with @quadrillion.io email)

        may opt into cross-user data by passing user_id (specific user) or

        all_users=true (everyone). Non-admin requests for other users'' data are

        silently scoped to the caller.'
