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.

+# CMxCustomEnumArray Class
+
+Namespace: `ArchestrA.Toolkit`
+
+CMxCustomEnumArray is derived from CMxArray and provides support for Enum Array Attributes.
+
+**Syntax**
+
+```csharp
+public class CMxCustomEnumArray : CMxArray<short>
+```
+
+## CMxCustomEnumArray Properties
+
+### Text Property
+
+Provides an EnumText to allow accessing elements as strings.
+
+**Syntax**
+
+```csharp
+public EnumText Text;
+```
+
+**Returns**
+
+EnumText
+
+### Value Property
+
+Provides a property to get and set the values of the ordinals as a short array.
+
+**Syntax**
+
+```csharp
+public short[] Value { get; set; }
+```
+
+**Returns**
+
+short[ ]
+
+### Property to get and set the value of an ordinal
+
+Provides a property to get and set the value of an ordinal element by short index.
+
+**Syntax**
+
+```csharp
+public short this[short i] { get; set; }
+```
+
+**Returns**
+
+short
+
+## CMxCustomEnumArray Constructors
+
+### CMxCustomEnumArray Constructor (string, int, short[ ])
+
+Provides a constructor to initialize the class with the name of an array, its depth relative to the owning object and an array of ordinals as short.
+
+**Syntax**
+
+```csharp
+public CMxCustomEnumArray(string arrayAttribute, int depth, short[] value);
+```
+
+**Parameters**
+
+**`arrayAttribute`**
+
+[in] string value that holds the name of the string array attribute.
+
+**`depth`**
+
+[in] int value that holds the relative depth of the string array attribute primitive.
+
+The depth assigned to the reference determines the location of the String Array reference (0 represents the local Primitive, -1 represents the Parent, -2 represents the Parents Parent and so on.)
+
+**`value`**
+
+[in] short[ ] value that holds the ordinal values.
+
+### CMxCustomEnumArray Constructor (string, int, int)
+
+Provides a constructor to initialize the class with the name of an array, its depth relative to the owning object and the default length.
+
+**Syntax**
+
+```csharp
+public CMxCustomEnumArray(string arrayAttribute, int depth, int length);
+```
+
+**Parameters**
+
+**`arrayAttribute`**
+
+[in] string value that holds the name of the string array attribute.
+
+**`depth`**
+
+[in] int value that holds the relative depth of the string array attribute primitive.
+
+The depth assigned to the reference determines the location of the String Array reference (0 represents the local Primitive, -1 represents the Parent, -2 represents the Parents Parent and so on.)
+
+**`length`**
+
+[in] int value that holds the array length.
+
+### CMxCustomEnumArray Constructor (SupportWrapper, string)
+
+Provides a constructor to initialize the class for use in a primitive wrapper.
+
+**Syntax**
+
+```csharp
+public CMxCustomEnumArray(SupportWrapper _wrapper, string _attributeRef);
+```
+
+**Parameters**
+
+**`_wrapper`**
+
+[in] SupportWrapper.
+
+**`_attributeRef`**
+
+[in] string value that holds the attribute reference.
+
+## CMxCustomEnumArray Methods
