1.1.0 - 2026-09-15

• Added an installable package skill for Repository and DataSource design, business-data normalization, source ownership, observation, and lifecycle.

1.0.0 - 2026-08-17

• Established stable Repository, DataSource container, replay-latest stream, mutation, ownership, and close contracts.
• Made repository close reentrant-safe and ensured owned stream subscriptions can finish cancellation before teardown completes.
• Documented the additive post-1.0 roadmap.

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.
