# Baltique OS Core 2.6.1
## Verified floorplans, room governance, runtime cache and UI controls repair

Release 2.6.1 formalises the spatial layer of the **Enterprise Hospital Command Center**. Operational map data is derived exclusively from the supplied source documents, while the approved **Premium Rose & Cream Strategic Hospital Map** style remains a locked presentation layer.

## Scope

- 3 sites, 8 levels and 119 verified room/space records;
- strict separation between presentation imagery and the operational source of truth;
- controlled room create, edit, archive, restore and delete workflows;
- revision history and protection of source-verified rooms;
- real request-scoped database metadata cache;
- global repair of empty/grey dropdown lists in light and dark themes;
- light-theme repair of Codebase Normalization scope cards;
- planned-site visibility restricted to authorised users;
- integration with Hospital Command Center, Module Registry, Migration Ledger and Runtime Preflight.

## Source of truth

- **Geometry, names, source identifiers and areas**: registered source documents with SHA256 evidence.
- **Premium illustrations**: presentation only, never architectural source data.
- **Database**: operational state source of truth.

## Current Sopot office rule

The source document confirms only:

```text
Unit 1.3
Level 0
56.00 m²
```

It does not confirm internal room functions. The system therefore does not invent consultation rooms, reception or waiting areas inside the unit. Internal subdivision requires an approved fit-out drawing or verified as-built survey.

## Required baseline
