# Semantic Versioning Policy

## Default Policy

- Patch: backward-compatible fixes.
- Minor: backward-compatible contract additions.
- Major: breaking contract changes.

## Stable Baseline Policy

- Stable decoupling baseline starts at `0.2.0`.
- All blueprint package outputs in the same release wave must share the same version.
- Breaking changes after baseline require major or minor strategy review before publication.

## Contract Compatibility

- Module package contracts are represented as descriptors implementing `IBlueprintPackageContract`.
- Consumer-impacting contract changes require version policy review before publish.
- Blueprint package contracts must remain identity-agnostic.
