+---
+
+## Critical Bugs
+
+### 1. Infinite Loop in PinnedTypes Enumerator
+**File:** `Foundation.Data.Doublets.Cli/PinnedTypes.cs:71`
+**Severity:** Critical
+**Description:** The `MoveNext()` method in `PinnedTypesEnumerator` always returns `true`, causing infinite loops when iterating.
+
+```csharp
+public bool MoveNext()
+{
+    // ... logic ...
+    _currentAddress++;
+    return true;  // Always returns true, never stops!
+}
+```
+
+**Impact:** Any code that uses `foreach` or LINQ operations on `PinnedTypes` will hang indefinitely.
+
+**Recommendation:** Add a condition to return `false` when reaching a maximum address or implement a proper termination condition.
+
+---
+
+### 2. Incorrect Type Conversion in LinksExtensions
+**File:** `Foundation.Data.Doublets.Cli/LinksExtensions.cs:14`
+**Severity:** High
+**Description:** Variables named `addressToUInt64Converter` and `uInt64ToAddressConverter` both use the same type `CheckedConverter<TLinkAddress, TLinkAddress>`, which doesn't actually perform any conversion.
+
+```csharp
+var addressToUInt64Converter = CheckedConverter<TLinkAddress, TLinkAddress>.Default;
+var uInt64ToAddressConverter = CheckedConverter<TLinkAddress, TLinkAddress>.Default;
+```
+
+**Impact:** The conversion logic is not working as intended, potentially causing incorrect behavior in link creation.
+
+**Recommendation:** These converters are actually unnecessary since no conversion is happening. Either remove them or fix the types if conversion is actually needed.
+
+---
+
+### 3. Variable Shadowing in ResolveId
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:662`
+**Severity:** High
+**Description:** The method uses `anyConstant` as both input and output parameter for `TryParseLinkId`, which shadows the original value and could lead to bugs.
+
+```csharp
+if (TryParseLinkId(identifier, links.Constants, ref anyConstant))
+{
+    return anyConstant;  // Returns modified anyConstant, not the parsed value
+}
+```
+
+**Impact:** Incorrect identifier resolution could cause query processing failures.
+
+**Recommendation:** Use a separate variable for the parsed value:
+```csharp
+uint parsedValue = anyConstant;
+if (TryParseLinkId(identifier, links.Constants, ref parsedValue))
+{
+    return parsedValue;
+}
+```
+
+---
+
+### 4. Potential Double Deletion in NamedLinks
+**File:** `Foundation.Data.Doublets.Cli/NamedLinks.cs:135`
+**Severity:** Medium
+**Description:** `RemoveNameByExternalReference` deletes `nameTypeToNameSequenceLink` and then calls `RemoveName(reference)` which might try to delete related links again.
+
+```csharp
+_links.Delete(nameTypeToNameSequenceLink);
+// ...
+RemoveName(reference);  // May attempt to delete already deleted links
+```
+
+**Impact:** Could cause exceptions or unexpected behavior when removing names.
+
+**Recommendation:** Review the deletion logic to ensure links are only deleted once and in the correct order.
+
+---
+
+## Consistency Issues
+
+### 1. Inconsistent TryParseLinkId Implementations
+**Files:**
+- `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:896` (returns `bool`)
+- `Foundation.Data.Doublets.Cli/MixedQueryProcessor.cs:319` (returns `void`)
+
+**Description:** Two query processors have similar functions with the same name but different signatures and behaviors.
+
+**Recommendation:** Standardize on a single implementation, preferably returning `bool` to indicate success/failure.
+
+---
+
+### 2. Missing Namespace in EnumerableExtensions
+**File:** `Foundation.Data.Doublets.Cli/EnumerableExtensions.cs`
+**Description:** This file defines extensions in the global namespace while all other files use `Foundation.Data.Doublets.Cli`.
+
+**Recommendation:** Add namespace declaration:
+```csharp
+namespace Foundation.Data.Doublets.Cli
+{
+    public static class EnumerableExtensions { ... }
+}
+```
+
+---
+
+### 3. Incorrect Console Message in SimpleLinksDecorator
+**File:** `Foundation.Data.Doublets.Cli/SimpleLinksDecorator.cs:43`
+**Description:** Copy-paste error - console message says "NamedLinksDecorator" instead of "SimpleLinksDecorator".
+
+```csharp
+Console.WriteLine($"[Trace] Constructing NamedLinksDecorator with names DB: {namesDatabaseFilename}");
+// Should be:
+Console.WriteLine($"[Trace] Constructing SimpleLinksDecorator with names DB: {namesDatabaseFilename}");
+```
+
+**Recommendation:** Fix the message to reflect the actual class name.
+
+---
+
+### 4. Duplicate Code Between Decorators
+**Files:**
+- `Foundation.Data.Doublets.Cli/NamedLinksDecorator.cs`
+- `Foundation.Data.Doublets.Cli/SimpleLinksDecorator.cs`
+
+**Description:** Both classes have nearly identical implementations of `MakeLinks`, `MakeNamesDatabaseFilename`, and constructors.
+
+**Recommendation:** Extract common functionality into a shared base class or utility class.
+
+---
+
+### 5. Inconsistent Query Processor Interfaces
+**Description:** Three query processors (`BasicQueryProcessor`, `MixedQueryProcessor`, `AdvancedMixedQueryProcessor`) have different method signatures for `ProcessQuery`:
+- Basic: `void ProcessQuery(ILinks<uint> links, string query)`
+- Mixed: `void ProcessQuery(ILinks<uint> links, Options options)`
+- Advanced: `void ProcessQuery(NamedLinksDecorator<uint> links, Options options)`
+
+**Recommendation:** Unify the interfaces with a common base interface or abstract class.
+
+---
+
+## Potential Bugs
+
+### 1. Unchecked Null Condition in Pattern Matching
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:105`
+**Description:** Condition `!IsNumericOrStar(single.Id)` may not work as intended when `single.Id` is null or empty, since `IsNumericOrStar` returns `false` for those cases.
+
+```csharp
+if (string.IsNullOrEmpty(single.Id) &&
+    single.Values?.Count == 2 && !IsNumericOrStar(single.Id))  // Always true when Id is null
+```
+
+**Recommendation:** Clarify the logic and possibly reorder or modify the conditions.
+
+---
+
+### 2. Redundant Logic in MixedQueryProcessor
+**File:** `Foundation.Data.Doublets.Cli/MixedQueryProcessor.cs:93`
+**Description:** Lines 79-92 and 93-101 appear to handle similar cases with slightly different conditions, possibly causing redundant or conflicting logic.
+
+**Recommendation:** Review and consolidate the variable assignment logic.
+
+---
+
+### 3. Suspicious ChangesHandler Call
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:803-806`
+**Description:** Calls `ChangesHandler` with identical before/after states using null constants, which seems incorrect.
+
+```csharp
+options.ChangesHandler?.Invoke(
+    new DoubletLink(linkDefinition.Index, nullConstant, nullConstant),
+    new DoubletLink(linkDefinition.Index, nullConstant, nullConstant)
+);
+```
+
+**Recommendation:** Review if this is intentional or if different values should be used.
+
+---
+
+### 4. No Error Handling for Parse Failures
+**File:** `Foundation.Data.Doublets.Cli/BasicQueryProcessor.cs:98-113`
+**Description:** Uses `uint.TryParse` but doesn't handle the `false` case explicitly, relying on default values which may not be appropriate.
+
+**Recommendation:** Add explicit error handling or validation for parsing failures.
+
+---
+
+### 5. Logic Issue in RemoveName
+**File:** `Foundation.Data.Doublets.Cli/NamedLinks.cs:112-117`
+**Description:** After deleting `nameCandidatePair`, checks if `nameTypeToNameSequenceLink` is used elsewhere, but the query may return incorrect results since the original link was already deleted.
+
+**Recommendation:** Check usage before deletion, not after.
+
+---
+
+### 6. Missing Validation in CreateCompositeLink
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:1172-1207`
+**Description:** No validation that `sourceLinkId` and `targetLinkId` are valid before creating composite links.
+
+**Recommendation:** Add validation to ensure child links exist or are valid values.
+
+---
+
+## Code Quality Issues
+
+### 1. Extremely Large File
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs` (1,209 lines)
+**Description:** This file is very large and contains complex nested logic, making it difficult to understand, test, and maintain.
+
+**Recommendation:** Refactor into smaller, focused classes:
+- PatternMatcher
+- SolutionApplier
+- LinkCreator
+- QueryValidator
+
+---
+
+### 2. Magic Strings and Values
+**Files:** Multiple
+**Description:** Hardcoded strings like `"$"` for variables, `"*"` for wildcards, and magic numbers are scattered throughout the code.
+
+**Recommendation:** Define constants:
+```csharp
+public static class QueryConstants
+{
+    public const string VariablePrefix = "$";
+    public const string WildcardSymbol = "*";
+    public const string IndexSuffix = ":";
+}
+```
+
+---
+
+### 3. Empty Interface Implementation
+**File:** `Foundation.Data.Doublets.Cli/ILinksUnrestricted.cs:3`
+**Description:** Contains a TODO comment and empty interfaces, suggesting incomplete implementation.
+
+```csharp
+// TODO: support ILinksUnrestricted<string> and TConstants
+public interface ILinksUnrestricted<TLinkAddress> { }
+```
+
+**Recommendation:** Either implement the interface or remove it if not needed.
+
+---
+
+### 4. Generic Exception Throwing
+**File:** `Foundation.Data.Doublets.Cli/UnicodeStringStorage.cs:150`
+**Description:** Throws generic `Exception` instead of a specific exception type.
+
+```csharp
+throw new Exception("The passed link does not contain a string.");
+```
+
+**Recommendation:** Create and use specific exception types:
+```csharp
+public class InvalidLinkFormatException : Exception { ... }
+throw new InvalidLinkFormatException("The passed link does not contain a string.");
+```
+
+---
+
+### 5. Mixed Language Documentation
+**Files:** Multiple files, especially `ILinksUnrestricted.cs`
+**Description:** XML documentation contains both English and Russian text, making it harder to maintain and understand.
+
+**Recommendation:** Standardize on English for all documentation, or separate language-specific docs into resource files.
+
+---
+
+### 6. Inconsistent Error Handling
+**Description:** Some methods log errors, some throw exceptions, some return error codes. No consistent error handling strategy.
+
+**Recommendation:** Establish and document a consistent error handling pattern across the codebase.
+
+---
+
+### 7. Lack of Input Validation
+**Files:** Multiple
+**Description:** Many public methods don't validate inputs, potentially allowing null or invalid values to cause issues deep in the call stack.
+
+**Recommendation:** Add guard clauses and validation at public API boundaries.
+
+---
+
+## Performance Issues
+
+### 1. Iterating All Links in Database
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:541`
+**Description:** Calls `links.All(new DoubletLink(anyConstant, anyConstant, anyConstant))` which retrieves ALL links from the database.
+
+```csharp
+var allLinks = links.All(new DoubletLink(anyConstant, anyConstant, anyConstant));
+foreach (var raw in allLinks) { ... }
+```
+
+**Impact:** For large databases with millions of links, this will be extremely slow and memory-intensive.
+
+**Recommendation:** Add indexes or use more specific queries to limit the search space. Consider using database-level optimizations or pagination.
+
+---
+
+### 2. Excessive List Conversions
+**File:** `Foundation.Data.Doublets.Cli/ChangesSimplifier.cs`
+**Description:** Multiple `.ToList()` calls and conversions that could be avoided.
+
+**Recommendation:** Use IEnumerable where possible and only materialize collections when necessary.
+
+---
+
+### 3. Repeated Link Lookups
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs`
+**Description:** Multiple calls to `links.GetLink()`, `links.Exists()`, and `links.GetName()` for the same link IDs without caching.
+
+**Recommendation:** Implement caching for frequently accessed links within a query operation.
+
+---
+
+### 4. String Operations in Hot Path
+**File:** `Foundation.Data.Doublets.Cli/Program.cs:157-171`
+**Description:** `Namify` function uses regex and string replacement in a loop, which is called for every link when printing.
+
+**Recommendation:** Cache name lookups or optimize the replacement logic.
+
+---
+
+## Thread Safety Issues
+
+### 1. No Synchronization in Decorators
+**Files:**
+- `Foundation.Data.Doublets.Cli/NamedLinksDecorator.cs`
+- `Foundation.Data.Doublets.Cli/SimpleLinksDecorator.cs`
+
+**Description:** These decorators maintain state but have no synchronization mechanisms for concurrent access.
+
+**Impact:** Race conditions could occur if the same decorator instance is used from multiple threads.
+
+**Recommendation:** Either document that instances are not thread-safe, or add appropriate synchronization.
+
+---
+
+### 2. Shared State in Query Processing
+**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs`
+**Description:** While the query processor is stateless (static), the Options object with ChangesHandler could be problematic if shared.
+
+**Recommendation:** Document thread-safety expectations for Options and handlers.
+
+---
+
+## Documentation Issues
+
+### 1. Missing XML Documentation
+**Description:** Many public methods and classes lack XML documentation comments.
+
+**Recommendation:** Add XML documentation for all public APIs to improve IntelliSense support and code understanding.
+
+---
+
+### 2. Incomplete README Examples
+**File:** `README.md`
+**Description:** README could benefit from more examples showing complex query patterns and use cases.
+
+**Recommendation:** Add comprehensive examples demonstrating:
+- Variable usage
+- Complex pattern matching
+- Named links
+- Common operations
+
+---
+
+### 3. No Architecture Documentation
+**Description:** No high-level architecture documentation explaining the relationship between query processors, decorators, and the links system.
+
+**Recommendation:** Add architecture diagrams and documentation explaining:
+- Query processing pipeline
+- Decorator pattern usage
+- Links storage system
+- Naming system
+
+---
+
+## Summary Statistics
+
+- **Critical Bugs:** 4
+- **Consistency Issues:** 5
+- **Potential Bugs:** 6
+- **Code Quality Issues:** 7
+- **Performance Issues:** 4
+- **Thread Safety Issues:** 2

----
-
-## Critical Bugs
-
-### 1. Infinite Loop in PinnedTypes Enumerator
-**File:** `Foundation.Data.Doublets.Cli/PinnedTypes.cs:71`
-**Severity:** Critical
-**Description:** The `MoveNext()` method in `PinnedTypesEnumerator` always returns `true`, causing infinite loops when iterating.
-
-```csharp
-public bool MoveNext()
-{
-    // ... logic ...
-    _currentAddress++;
-    return true;  // Always returns true, never stops!
-}
-```
-
-**Impact:** Any code that uses `foreach` or LINQ operations on `PinnedTypes` will hang indefinitely.
-
-**Recommendation:** Add a condition to return `false` when reaching a maximum address or implement a proper termination condition.
-
----
-
-### 2. Incorrect Type Conversion in LinksExtensions
-**File:** `Foundation.Data.Doublets.Cli/LinksExtensions.cs:14`
-**Severity:** High
-**Description:** Variables named `addressToUInt64Converter` and `uInt64ToAddressConverter` both use the same type `CheckedConverter<TLinkAddress, TLinkAddress>`, which doesn't actually perform any conversion.
-
-```csharp
-var addressToUInt64Converter = CheckedConverter<TLinkAddress, TLinkAddress>.Default;
-var uInt64ToAddressConverter = CheckedConverter<TLinkAddress, TLinkAddress>.Default;
-```
-
-**Impact:** The conversion logic is not working as intended, potentially causing incorrect behavior in link creation.
-
-**Recommendation:** These converters are actually unnecessary since no conversion is happening. Either remove them or fix the types if conversion is actually needed.
-
----
-
-### 3. Variable Shadowing in ResolveId
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:662`
-**Severity:** High
-**Description:** The method uses `anyConstant` as both input and output parameter for `TryParseLinkId`, which shadows the original value and could lead to bugs.
-
-```csharp
-if (TryParseLinkId(identifier, links.Constants, ref anyConstant))
-{
-    return anyConstant;  // Returns modified anyConstant, not the parsed value
-}
-```
-
-**Impact:** Incorrect identifier resolution could cause query processing failures.
-
-**Recommendation:** Use a separate variable for the parsed value:
-```csharp
-uint parsedValue = anyConstant;
-if (TryParseLinkId(identifier, links.Constants, ref parsedValue))
-{
-    return parsedValue;
-}
-```
-
----
-
-### 4. Potential Double Deletion in NamedLinks
-**File:** `Foundation.Data.Doublets.Cli/NamedLinks.cs:135`
-**Severity:** Medium
-**Description:** `RemoveNameByExternalReference` deletes `nameTypeToNameSequenceLink` and then calls `RemoveName(reference)` which might try to delete related links again.
-
-```csharp
-_links.Delete(nameTypeToNameSequenceLink);
-// ...
-RemoveName(reference);  // May attempt to delete already deleted links
-```
-
-**Impact:** Could cause exceptions or unexpected behavior when removing names.
-
-**Recommendation:** Review the deletion logic to ensure links are only deleted once and in the correct order.
-
----
-
-## Consistency Issues
-
-### 1. Inconsistent TryParseLinkId Implementations
-**Files:**
-- `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:896` (returns `bool`)
-- `Foundation.Data.Doublets.Cli/MixedQueryProcessor.cs:319` (returns `void`)
-
-**Description:** Two query processors have similar functions with the same name but different signatures and behaviors.
-
-**Recommendation:** Standardize on a single implementation, preferably returning `bool` to indicate success/failure.
-
----
-
-### 2. Missing Namespace in EnumerableExtensions
-**File:** `Foundation.Data.Doublets.Cli/EnumerableExtensions.cs`
-**Description:** This file defines extensions in the global namespace while all other files use `Foundation.Data.Doublets.Cli`.
-
-**Recommendation:** Add namespace declaration:
-```csharp
-namespace Foundation.Data.Doublets.Cli
-{
-    public static class EnumerableExtensions { ... }
-}
-```
-
----
-
-### 3. Incorrect Console Message in SimpleLinksDecorator
-**File:** `Foundation.Data.Doublets.Cli/SimpleLinksDecorator.cs:43`
-**Description:** Copy-paste error - console message says "NamedLinksDecorator" instead of "SimpleLinksDecorator".
-
-```csharp
-Console.WriteLine($"[Trace] Constructing NamedLinksDecorator with names DB: {namesDatabaseFilename}");
-// Should be:
-Console.WriteLine($"[Trace] Constructing SimpleLinksDecorator with names DB: {namesDatabaseFilename}");
-```
-
-**Recommendation:** Fix the message to reflect the actual class name.
-
----
-
-### 4. Duplicate Code Between Decorators
-**Files:**
-- `Foundation.Data.Doublets.Cli/NamedLinksDecorator.cs`
-- `Foundation.Data.Doublets.Cli/SimpleLinksDecorator.cs`
-
-**Description:** Both classes have nearly identical implementations of `MakeLinks`, `MakeNamesDatabaseFilename`, and constructors.
-
-**Recommendation:** Extract common functionality into a shared base class or utility class.
-
----
-
-### 5. Inconsistent Query Processor Interfaces
-**Description:** Three query processors (`BasicQueryProcessor`, `MixedQueryProcessor`, `AdvancedMixedQueryProcessor`) have different method signatures for `ProcessQuery`:
-- Basic: `void ProcessQuery(ILinks<uint> links, string query)`
-- Mixed: `void ProcessQuery(ILinks<uint> links, Options options)`
-- Advanced: `void ProcessQuery(NamedLinksDecorator<uint> links, Options options)`
-
-**Recommendation:** Unify the interfaces with a common base interface or abstract class.
-
----
-
-## Potential Bugs
-
-### 1. Unchecked Null Condition in Pattern Matching
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:105`
-**Description:** Condition `!IsNumericOrStar(single.Id)` may not work as intended when `single.Id` is null or empty, since `IsNumericOrStar` returns `false` for those cases.
-
-```csharp
-if (string.IsNullOrEmpty(single.Id) &&
-    single.Values?.Count == 2 && !IsNumericOrStar(single.Id))  // Always true when Id is null
-```
-
-**Recommendation:** Clarify the logic and possibly reorder or modify the conditions.
-
----
-
-### 2. Redundant Logic in MixedQueryProcessor
-**File:** `Foundation.Data.Doublets.Cli/MixedQueryProcessor.cs:93`
-**Description:** Lines 79-92 and 93-101 appear to handle similar cases with slightly different conditions, possibly causing redundant or conflicting logic.
-
-**Recommendation:** Review and consolidate the variable assignment logic.
-
----
-
-### 3. Suspicious ChangesHandler Call
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:803-806`
-**Description:** Calls `ChangesHandler` with identical before/after states using null constants, which seems incorrect.
-
-```csharp
-options.ChangesHandler?.Invoke(
-    new DoubletLink(linkDefinition.Index, nullConstant, nullConstant),
-    new DoubletLink(linkDefinition.Index, nullConstant, nullConstant)
-);
-```
-
-**Recommendation:** Review if this is intentional or if different values should be used.
-
----
-
-### 4. No Error Handling for Parse Failures
-**File:** `Foundation.Data.Doublets.Cli/BasicQueryProcessor.cs:98-113`
-**Description:** Uses `uint.TryParse` but doesn't handle the `false` case explicitly, relying on default values which may not be appropriate.
-
-**Recommendation:** Add explicit error handling or validation for parsing failures.
-
----
-
-### 5. Logic Issue in RemoveName
-**File:** `Foundation.Data.Doublets.Cli/NamedLinks.cs:112-117`
-**Description:** After deleting `nameCandidatePair`, checks if `nameTypeToNameSequenceLink` is used elsewhere, but the query may return incorrect results since the original link was already deleted.
-
-**Recommendation:** Check usage before deletion, not after.
-
----
-
-### 6. Missing Validation in CreateCompositeLink
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:1172-1207`
-**Description:** No validation that `sourceLinkId` and `targetLinkId` are valid before creating composite links.
-
-**Recommendation:** Add validation to ensure child links exist or are valid values.
-
----
-
-## Code Quality Issues
-
-### 1. Extremely Large File
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs` (1,209 lines)
-**Description:** This file is very large and contains complex nested logic, making it difficult to understand, test, and maintain.
-
-**Recommendation:** Refactor into smaller, focused classes:
-- PatternMatcher
-- SolutionApplier
-- LinkCreator
-- QueryValidator
-
----
-
-### 2. Magic Strings and Values
-**Files:** Multiple
-**Description:** Hardcoded strings like `"$"` for variables, `"*"` for wildcards, and magic numbers are scattered throughout the code.
-
-**Recommendation:** Define constants:
-```csharp
-public static class QueryConstants
-{
-    public const string VariablePrefix = "$";
-    public const string WildcardSymbol = "*";
-    public const string IndexSuffix = ":";
-}
-```
-
----
-
-### 3. Empty Interface Implementation
-**File:** `Foundation.Data.Doublets.Cli/ILinksUnrestricted.cs:3`
-**Description:** Contains a TODO comment and empty interfaces, suggesting incomplete implementation.
-
-```csharp
-// TODO: support ILinksUnrestricted<string> and TConstants
-public interface ILinksUnrestricted<TLinkAddress> { }
-```
-
-**Recommendation:** Either implement the interface or remove it if not needed.
-
----
-
-### 4. Generic Exception Throwing
-**File:** `Foundation.Data.Doublets.Cli/UnicodeStringStorage.cs:150`
-**Description:** Throws generic `Exception` instead of a specific exception type.
-
-```csharp
-throw new Exception("The passed link does not contain a string.");
-```
-
-**Recommendation:** Create and use specific exception types:
-```csharp
-public class InvalidLinkFormatException : Exception { ... }
-throw new InvalidLinkFormatException("The passed link does not contain a string.");
-```
-
----
-
-### 5. Mixed Language Documentation
-**Files:** Multiple files, especially `ILinksUnrestricted.cs`
-**Description:** XML documentation contains both English and Russian text, making it harder to maintain and understand.
-
-**Recommendation:** Standardize on English for all documentation, or separate language-specific docs into resource files.
-
----
-
-### 6. Inconsistent Error Handling
-**Description:** Some methods log errors, some throw exceptions, some return error codes. No consistent error handling strategy.
-
-**Recommendation:** Establish and document a consistent error handling pattern across the codebase.
-
----
-
-### 7. Lack of Input Validation
-**Files:** Multiple
-**Description:** Many public methods don't validate inputs, potentially allowing null or invalid values to cause issues deep in the call stack.
-
-**Recommendation:** Add guard clauses and validation at public API boundaries.
-
----
-
-## Performance Issues
-
-### 1. Iterating All Links in Database
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs:541`
-**Description:** Calls `links.All(new DoubletLink(anyConstant, anyConstant, anyConstant))` which retrieves ALL links from the database.
-
-```csharp
-var allLinks = links.All(new DoubletLink(anyConstant, anyConstant, anyConstant));
-foreach (var raw in allLinks) { ... }
-```
-
-**Impact:** For large databases with millions of links, this will be extremely slow and memory-intensive.
-
-**Recommendation:** Add indexes or use more specific queries to limit the search space. Consider using database-level optimizations or pagination.
-
----
-
-### 2. Excessive List Conversions
-**File:** `Foundation.Data.Doublets.Cli/ChangesSimplifier.cs`
-**Description:** Multiple `.ToList()` calls and conversions that could be avoided.
-
-**Recommendation:** Use IEnumerable where possible and only materialize collections when necessary.
-
----
-
-### 3. Repeated Link Lookups
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs`
-**Description:** Multiple calls to `links.GetLink()`, `links.Exists()`, and `links.GetName()` for the same link IDs without caching.
-
-**Recommendation:** Implement caching for frequently accessed links within a query operation.
-
----
-
-### 4. String Operations in Hot Path
-**File:** `Foundation.Data.Doublets.Cli/Program.cs:157-171`
-**Description:** `Namify` function uses regex and string replacement in a loop, which is called for every link when printing.
-
-**Recommendation:** Cache name lookups or optimize the replacement logic.
-
----
-
-## Thread Safety Issues
-
-### 1. No Synchronization in Decorators
-**Files:**
-- `Foundation.Data.Doublets.Cli/NamedLinksDecorator.cs`
-- `Foundation.Data.Doublets.Cli/SimpleLinksDecorator.cs`
-
-**Description:** These decorators maintain state but have no synchronization mechanisms for concurrent access.
-
-**Impact:** Race conditions could occur if the same decorator instance is used from multiple threads.
-
-**Recommendation:** Either document that instances are not thread-safe, or add appropriate synchronization.
-
----
-
-### 2. Shared State in Query Processing
-**File:** `Foundation.Data.Doublets.Cli/AdvancedMixedQueryProcessor.cs`
-**Description:** While the query processor is stateless (static), the Options object with ChangesHandler could be problematic if shared.
-
-**Recommendation:** Document thread-safety expectations for Options and handlers.
-
----
-
-## Documentation Issues
-
-### 1. Missing XML Documentation
-**Description:** Many public methods and classes lack XML documentation comments.
-
-**Recommendation:** Add XML documentation for all public APIs to improve IntelliSense support and code understanding.
-
----
-
-### 2. Incomplete README Examples
-**File:** `README.md`
-**Description:** README could benefit from more examples showing complex query patterns and use cases.
-
-**Recommendation:** Add comprehensive examples demonstrating:
-- Variable usage
-- Complex pattern matching
-- Named links
-- Common operations
-
----
-
-### 3. No Architecture Documentation
-**Description:** No high-level architecture documentation explaining the relationship between query processors, decorators, and the links system.
-
-**Recommendation:** Add architecture diagrams and documentation explaining:
-- Query processing pipeline
-- Decorator pattern usage
-- Links storage system
-- Naming system
-
----
-
-## Summary Statistics
-
-- **Critical Bugs:** 4
-- **Consistency Issues:** 5
-- **Potential Bugs:** 6
-- **Code Quality Issues:** 7
-- **Performance Issues:** 4
-- **Thread Safety Issues:** 2
-- **Documentation Issues:** 3
-
-**Total Issues:** 31
-
----
-

Subject: [PATCH 3/6] Add CI workflow for pull request and branch validation

Add comprehensive CI workflow that runs on:
- Pull requests to main/master/develop branches
- Pushes to main/master/develop branches

The workflow performs:
- Dependency restoration
- Release build
- Test execution with code coverage
- Test results upload as artifacts
- Build summary generation

This ensures all PRs are validated before merging and helps catch
breaking changes early in the development process.

The existing csharp.yml workflow remains for release publishing
when version tags are pushed.

Subject: [PATCH 6/6] Fix indentation in EnumerableExtensions.cs

Correct method indentation inside the EnumerableExtensions class.
The methods were not properly indented, causing compilation errors.
All Deconstruct methods are now properly indented with 8 spaces
(2 levels: namespace + class).
