# Vision

Make model-assisted annotation quick to inspect, correct, and repeat without
turning one model output or one reviewer decision into an irreversible label.

# First use case

The first adapter reviews NuCLS nucleus boxes and mask proposals. Reviewers
decide whether a box contains a valid nucleus before judging its mask. CellSAM
provides the primary mask proposal and SAM 2.1 provides a faster independent
alternative when the models disagree.

# Boundary

The app owns generic review contracts, review events, and the browser workflow.
Dataset projects own source access, frozen splits, ontology semantics,
coordinate conversion, and model inference. Review bundles contain derived
assets and provenance. They do not replace source manifests.
