-## Security Classification
-
-Galaxy attributes carry a `security_classification` that controls OPC UA write access. The server maps these to `AccessLevel` on each variable node:
-
-| Classification | Galaxy Level | OPC UA Access |
-|---|---|---|
-| 0 | FreeAccess | ReadWrite |
-| 1 | Operate | ReadWrite |
-| 2 | SecuredWrite | ReadOnly |
-| 3 | VerifiedWrite | ReadOnly |
-| 4 | Tune | ReadWrite |
-| 5 | Configure | ReadWrite |
-| 6 | ViewOnly | ReadOnly |
-
-See `gr/data_type_mapping.md` for the full mapping table.
-
-## Alarm Tracking
-
-When `AlarmTrackingEnabled` is true, the server creates `AlarmConditionState` nodes for Galaxy attributes with `AlarmExtension` primitives. It auto-subscribes to each alarm's `InAlarm` tag and reports OPC UA alarm events on state transitions:
-
-- `InAlarm` TRUE → alarm active event (severity from `Priority`, message from `DescAttrName`)
-- `InAlarm` FALSE → alarm cleared event
-- Condition refresh reports all currently retained alarms to newly subscribing clients
-
-## Historical Data Access
-
-When `Historian.Enabled` is true, the server handles OPC UA `HistoryRead` requests by querying the Wonderware Historian `Runtime` database:
-
-- **Raw reads** query `Runtime.dbo.History` with time range and max values
-- **Processed reads** query `Runtime.dbo.AnalogSummaryHistory` with aggregates (Average, Minimum, Maximum, Count)
-- Historized variables advertise `Historizing=true` and `AccessLevel` includes `HistoryRead`
-
-## Incremental Address Space Sync
-
-When the Galaxy detects a new deployment, the server compares the previous hierarchy and attributes against the new snapshot. Only changed gobject subtrees are torn down and rebuilt — unchanged nodes, subscriptions, and alarm tracking remain intact. See `partial_update.md` for details.
-
-## Configuration
-
-All settings in `appsettings.json`, overridable via environment variables:
-
-| Section | Key | Default | Description |
-|---------|-----|---------|-------------|
-| `OpcUa` | `Port` | `4840` | OPC UA server port |
-| `OpcUa` | `EndpointPath` | `/LmxOpcUa` | Endpoint path |
-| `OpcUa` | `GalaxyName` | `ZB` | Galaxy name (namespace URI) |
-| `OpcUa` | `MaxSessions` | `100` | Maximum concurrent sessions |
-| `OpcUa` | `AlarmTrackingEnabled` | `false` | Enable alarm condition tracking |
-| `MxAccess` | `ClientName` | `LmxOpcUa` | MXAccess registration name |
-| `MxAccess` | `AutoReconnect` | `true` | Auto-reconnect on disconnect |
-| `MxAccess` | `ProbeTag` | `null` | Tag for connection health probing |
-| `GalaxyRepository` | `ConnectionString` | `Server=localhost;Database=ZB;...` | ZB database connection |
-| `GalaxyRepository` | `ChangeDetectionIntervalSeconds` | `30` | Deploy change polling interval |
-| `GalaxyRepository` | `ExtendedAttributes` | `false` | Include primitive/system attributes |
-| `Historian` | `Enabled` | `false` | Enable OPC UA historical data access |
-| `Historian` | `ConnectionString` | `Server=localhost;Database=Runtime;...` | Historian Runtime database connection |
-| `Historian` | `MaxValuesPerRead` | `10000` | Maximum values per HistoryRead request |
-| `Dashboard` | `Enabled` | `true` | Enable HTTP status dashboard |
-| `Dashboard` | `Port` | `8081` | Dashboard port |
-
-## Data Type Mapping
-
-| Galaxy Type | mx_data_type | OPC UA Type | NodeId |
-|-------------|-------------|-------------|--------|
-| Boolean | 1 | Boolean | i=1 |
-| Integer | 2 | Int32 | i=6 |
-| Float | 3 | Float | i=10 |
-| Double | 4 | Double | i=11 |
-| String | 5 | String | i=12 |
-| DateTime | 6 | DateTime | i=13 |
-| ElapsedTime | 7 | Double (seconds) | i=11 |
-| Reference | 8 | String | i=12 |
-| Enumeration | 13 | Int32 | i=6 |
-| InternationalizedString | 15 | LocalizedText | i=21 |
-
-Array attributes use `ValueRank=1` with `ArrayDimensions` from the Galaxy attribute definition.

-## Startup Sequence
-
-1. Load and validate configuration
-2. Register `AppDomain.UnhandledException` handler
-3. Create performance metrics
-4. Connect MXAccess (STA thread + COM registration)
-5. Start MXAccess monitor loop
-6. Test Galaxy database connection
-7. Start OPC UA server with programmatic config
-8. Query hierarchy + attributes, build address space
-9. Create alarm condition nodes and auto-subscribe to InAlarm tags (if enabled)
-10. Start change detection polling (incremental sync on deploy)
-11. Start status dashboard (HTML + JSON + health endpoint)
