Heldar kernel library.
The domain-agnostic, open (Apache-2.0) platform: media/DVR control plane (camera registry,
RTSP ingest, recording, timeline index, playback, live view), the perception ingest + sampler
framework and its DetectionConsumer seam, the zone engine, auth/RBAC, observability, retention,
remote-access overlay awareness, and the worker SDK contract. Domain applications link this crate
and plug in as consumers / route modules via the composing server binary.
Generic reference apps (heldar-entry, heldar-movement, heldar-search) are also
Apache-2.0 and live alongside this crate; vertical/client products (Campus Entry, BakerySense, …)
are proprietary crates that depend on the generic ones. See ARCHITECTURE.md for the open-core
split and docs/REMOTE-ACCESS.md for the remote-access model.
