A production rollout exposes a contract mismatch between the UI boundary and the owning service. The affected area is SSR loader.
Repair the SSR loader module boundary implementation so it ranks change-prone modules, preserves ownership boundaries, and identifies where characterization tests are required before extraction.
Evidence
- Affected surface: Full-stack frontend focus / SSR loader.
- Observed failure family: choose a safe refactoring boundary.
- Scope policy: region must equal eu-west.
