## [0.1.1] - 2025-12-02

### Added
- `/v1` REST surface backed by shared `labeling_ir` structs with new Ecto schemas (Queue, Schema, Sample, Assignment, Label, Dataset), tenant-scoped migrations, and assignment retrieval using stored samples.
- `Anvil.API.Router` and `Anvil.API.State` wired through Plug.Cowboy to expose CRUD operations with tenant isolation enforced via `X-Tenant-ID` and actor context.
