ark_data_layer 0.1.0-dev.1

Pure Dart foundations for repositories, data sources, and observable business data.

Changelog

0.1.0-dev.1 - 2026-08-10

• Added the Repository<Data> base class with observable current business data, protected replacement and update operations, and idempotent closing.
• Added replay-latest broadcast delivery with ordered asynchronous publications and independent subscription lifecycle.
• Added the DataSource marker contract and immutable DataSourceContainer with strict missing and ambiguous resolution errors.
• Kept DataSource construction, ownership, and finalization outside the repository container so composition scopes can manage shared resources.
• Added deterministic coverage for resolution, publication, reentrancy, subscription control, cleanup, and closed-state invariants.
