Struct ComparisonViewportGrid 

pub struct ComparisonViewportGrid {
    pub grid_version: String,
    pub source_frequency: String,
    pub requested_view_start_time: Option<Timestamp>,
    pub requested_view_end_time: Option<Timestamp>,
    pub viewport_width_px: i32,
    pub bucket_size_bars: i64,
    pub source_point_count: i64,
    pub view_source_point_count: i64,
    pub returned_bucket_count: i64,
}

Metadata for the deterministic, UTC-anchored comparison_grid_v1 contract.

Implementations clamp viewport_width_px to 64..8192 and then round it up to a 128px step. They calculate the number of canonical source-frequency slots intersecting the half-open requested viewport, divide that count by the normalized width, and round the result up to the next positive power of two. That value is bucket_size_bars. Bucket zero is anchored at the Unix epoch; display_time is the canonical timestamp of the final source Bar slot in the bucket. See comparison_grid_v1_test_vectors.json for conformance cases.
