# Baltique OS Core 2.1.0
## Enterprise Codebase Normalization Release

Baltique OS 2.1.0 is a cumulative normalization release built on the current 2.0/2.0.1 codebase. It does not introduce a new clinical pathway. It consolidates the platform into one governed Enterprise OS line before UAT and controlled clinical deployment.

## Release goals

- remove visible stale Core/version language from operational UI;
- replace hard-coded asset cache-busters with the current release version;
- consolidate the global CSS loading order and fix sidebar/layout clipping;
- preserve submit-button action values and use one canonical action router;
- govern legacy upgrade routes instead of exposing them as normal work paths;
- add request IDs, structured runtime error logging and a controlled error page;
- add request-scoped metadata caching and query instrumentation without caching clinical rows across requests;
- keep official Polish and English UI editions;
- enforce role-specific navigation and registered technical-route access;
- replace the former integrity scanners with one token-aware, database-backed normalization scanner.
