+- Core.Blueprint.Logging
+- Core.Blueprint.Mongo
+- Core.Blueprint.Redis
+- Core.Blueprint.SQLServer
+- Core.Blueprint.Storage
+- Core.Blueprint.KeyVault
+
+## Publishing Baseline
+
+- Publish packages independently from this repository.
+- Maintain explicit package dependency on `Core.Blueprint.Common` for all feature modules.
+- Keep package identifiers stable to protect downstream compatibility.

+# Semantic Versioning Policy
+
+## Default Policy
+
+- Patch: backward-compatible fixes.
+- Minor: backward-compatible contract additions.
+- Major: breaking contract changes.
+
+## 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.
