Module consumer 

The kernel’s perception-consumer seam.

The media + AI-task kernel is domain-agnostic: it samples frames, accepts detections from workers, and persists them. Anything that interprets those detections into domain events — the zone engine (spatial rules), the ANPR/access-control engine (plate authorization), and other domain verticals — plug in here as a DetectionConsumer rather than being wired into the ingest handler or crate::state::AppState directly.

This inverts the dependency: ingest fans a committed batch out to a registry of consumers; a consumer self-declares which task_types it cares about. New apps are added to the registry (and, after the crate split, linked in by the composing binary or fed over the event stream) — the kernel never gains an if task_type == "..." branch.

Structs

DetectionBatch

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).

Traits

DetectionConsumer

A pluggable interpreter of detection batches. Implementors live in their own module/crate (zones is kernel-open; ANPR/entry is a proprietary app) and are registered into crate::state::AppState.
