+Completion: ConfigKit `v0.8.0` is selected at commit
+`137769f3f18a370c68444242fb5d88e620e307e5`; its attribution links and module
+checksums are updated. The Go consumer minimum remains `1.26.0`. No
+`SourceInfo` comparability-dependent code required adjustment. Validation passed:
+`GOWORK=off go test ./internal/configuration .` and
+`GOWORK=off python3 scripts/check-examples.py`.

 ## Stage 2: Add Shared Resource Naming Primitives
 
 Scope: small private domain helpers and focused behavior tests.
