Struct DetectionBatch 

pub struct DetectionBatch<'a> {
    pub camera_id: &'a str,
    pub site_id: Option<&'a str>,
    pub task_type: &'a str,
    pub detections: &'a [DetectionIngest],
    pub timestamp: DateTime<Utc>,
}

One committed batch of detections handed to consumers after it is persisted. Carries the site/camera/task context so a consumer needs no extra lookups (and so the seam is tenant-aware for distributed deployments).

Fields

camera_id: &'a str

site_id: Option<&'a str>

task_type: &'a str

The task type that produced this batch (consumers self-select on it; e.g. BakerySense may also inspect it). Part of the stable seam contract.

detections: &'a [DetectionIngest]

timestamp: DateTime<Utc>

Worker-supplied capture time (engines that need trustworthy timing use server time instead; time-windowing consumers like BakerySense use this).
