Joseph Doherty 32f26272ae Initial commit: Wonderware / System Platform tools and reference
Five tools under one repo, all docs organized per DOCS-GUIDE.md:

- aalogcli: .NET 4.8 / x86 CliFx CLI for reading System Platform binary
  logs (*.aaLGX) for LLM debugging, built on aaOpenSource/aaLog. Commands:
  last, tail, range, unread, fields. Stable JSON envelope under --llm-json.
  Build template under lib/build/ for rebuilding aaLogReader.dll.

- aot: ArchestrA Object Toolkit 2014 v4.0 reference material. Dev guide
  (Markdown converted from CHM), API reference for the ArchestrA.Toolkit
  namespace, and the Monitor / Watchdog VS sample solutions.

- graccesscli: .NET 4.8 / x86 CliFx CLI that automates Galaxy
  configuration via the ArchestrA GRAccess COM interop. Includes session
  daemon, IPC protocol, and llm-json envelope contract.

- grdb: SQL/DDL exploration of the Galaxy Repository database. DDL
  captures, reusable queries, hierarchy / contained-name <-> tag-name
  translation notes.

- histdb: LLM-oriented reference for AVEVA Historian retrieval. INSQL
  linked-server, extension tables, every wwXxx time-domain extension,
  every retrieval mode, alarm/event SQL recipes, REST API. Distilled
  from the 243-page Historian Retrieval Guide.

Root contains:
- CLAUDE.md: thin index pointing into each tool's README.
- DOCS-GUIDE.md: doctrine for organizing docs for LLM consumption.

Namespace: `ArchestrA.Toolkit`
CMxVariantArray is derived from CMxArray and provides support for Variant Array Attributes.
**Syntax**
```csharp
public class CMxVariantArray : CMxArray<CMxValue)
```
## CMxVariantArray Properties
### Value Property
Provides a property to get and set the value as a CMxValue array.
**Syntax**
```csharp
public CMxValue [] Value { get; set; }
```
**Returns**
CMxValue [ ]
### Property to Get and Set the CMxValue Value using the [ ] Operator
Provides a property to get and set the CMxValue of an element using [ ] operator.
**Syntax**
```csharp
public CMxValue this[short i] { get; set; }
```
**Returns**
CMxValue
## CMxVariantArray Constructors
### CMxVariantArray Constructor int
Provides a constructor to initialize the array to a default length.
**Syntax**
```csharp
public CMxVariantArray(int length);
```
**Parameters**
**`length`**
[in] integer value that holds the array length.
### CMxVariantArray Constructor CMxValue[ ]
Provides a constructor to initialize the class with a CMxValue array default value.
**Syntax**
```csharp
public CMxVariantArray (CMxValue[] value);
```
**Parameters**
**`value`**
[in] CMxValue[ ] value to be set.
### CMxVariantArray Constructor SupportWrapper, string
Provides a constructor to initialize the class for use in a primitive wrapper.
**Syntax**
```csharp
public CMxVariantArray (SupportWrapper _wrapper, string _attributeRef);
```
**Parameters**
**`_wrapper`**
[in] SupportWrapper.
**`_attributeRef`**
[in] string value that holds the attribute reference.
## CMxVariantArray Methods
### Set Method
Provides a method to set the value of the Attribute from a CMxVariantArray.

```
**Parameters**
**`newValue`**
[in] CMxVariantArray value to be set.
### SetDataType Method
Provides a method to set the value of the MxDataType of the Attribute.
**Syntax**
```csharp
public void SetDataType(MxDataType dtype);
```
**Parameters**
**`dtype`**
[in] MxDataType value.
## CMxVariantArray Operator Overloads
### CMxValue Operator Overload CMxVariantArray
Provides an operator that converts from CMxVariantArray to CMxValue.
**Syntax**
```csharp
public static implicit operator CMxValue(CMxVariantArray val);
```
**Parameters**
**`val`**
[in] CMxVariantArray value to convert to CMxValue.
**Returns**
CMxValue
