Introduced a new "SGenOnly" build configuration across the solution, updating Directory.Build.props, AyCode.Core.targets, and the .sln file for full support. Centralized TargetFramework and build properties in AyCode.Core.targets, removing redundancy from project files. Updated code to recognize SGEN_ONLY at compile time. Added new Bash commands for file conversion and cleanup. No functional code changes outside build and configuration logic.
Major refactor: all benchmark engine implementations, enums, and helpers moved from Console project to AyCode.Core.Benchmarks.Workloads.Scenarios for unified cross-runner use. BenchmarkResult and reporting logic moved to AyCode.Core.Benchmarks.Reporting. Attribute-flag aggregation centralized in BenchmarkOptions. Updated all usages, project references, and SGen codegen for ref-handling. Prepares codebase for shared reporting and future extensibility.

Updated all related READMEs, glossaries, and conventions to reference this architecture and clarify grid infrastructure (MgGridBase, FruitBankGridBase) and external dependency locations (AyCode.Core, AyCode.Blazor, Mango.Nop Libraries, FruitBank Plugin). Synchronized solution items and copilot-instructions. Improves discoverability, enforces conventions, and clarifies tech debt for all developers.

- Updated solution file to include new project and build configs.
- Minor code cleanups and documentation improvements.
Introduced AcToonSerializer, a new high-performance, LLM-friendly serialization format (Toon) with explicit meta/types/data sections, rich type metadata, and smart inference for property documentation. Added ToonDescriptionAttribute for custom schema annotations and relationship metadata. Implemented fallback/placeholder system merging custom, Microsoft, and inferred metadata. Enhanced logging: AcLoggerBase now implements ILogger, with provider/extensions for DI integration. Updated SignalR client to use AcLogger. Added ToonExtendedInfo.txt with full documentation. No breaking changes to existing serialization.
Introduces Toon (Token-Oriented Object Notation), a new serialization format designed for LLM readability and token efficiency. Adds core Toon serializer, options, attribute system (ToonDescriptionAttribute), and comprehensive documentation. Supports explicit type metadata, smart fallback/placeholder logic, multi-turn workflows, reference handling, and multi-line strings. No breaking changes; Toon is opt-in and complements existing JSON/binary serializers.
Introduce Roslyn Source Generator for AcBinary serialization, generating optimized Serialize/Deserialize methods for types marked with [AcBinarySerializable]. Integrate generator as analyzer in core, tests, and benchmarks. Update metadata to detect generated serializers. Add benchmarks and integration tests to validate performance and correctness. Update project files and internals visibility for testing. Existing runtime serialization remains as fallback.
- Introduced a high-performance, reusable "chain" API for JSON deserialization and object population, enabling parsed JSON to be reused for multiple deserializations without reparsing. Exposed via new extension methods and interfaces (`IDeserializeChain<T>`, `IPopulateChain`).
- Added comprehensive infrastructure for serializing and deserializing .NET Expression trees to a universal DTO (`AcExpressionNode`), with full round-trip support and robust handling of constants, closures, and queryable expressions.
- Centralized all property accessor and expression utilities in `AcSerializerCommon` to avoid duplication and improve maintainability.
- Enhanced both JSON and binary serializers to support Expression and IQueryable types, with automatic conversion to/from `AcExpressionNode`.
- Refactored type metadata and property accessor logic for performance and code reuse.
- Added extensive unit tests for the new chain API and expression serialization, and reorganized test models and namespaces for clarity.
- Improved logging, error handling, and test infrastructure.
- Misc: Added settings for local builds, updated project files, and cleaned up obsolete code.
Majorly enhanced QuickBenchmark.cs with new helper methods, standardized iteration count, and several comprehensive benchmarks comparing AcBinary (with/without reference handling) to MessagePack. Improved output formatting for clarity. Added RunQuickBenchmark.ps1 and .bat scripts for easy CLI execution and registered them as solution items. These changes make benchmarking more robust, readable, and user-friendly.
Renamed the benchmark project from BenchmarkSuite1 to AyCode.Benchmark, updating the solution reference and moving all benchmark source files under the new project and namespace. No functional changes were made; this is a structural and naming reorganization for clarity and maintainability.

- Added AcJsonDeserializationException for clearer error reporting.
- Robust JSON validation, type checking, and double-serialization detection.
- Fast-path primitive (de)serialization for all common .NET types.

- Enhanced $id/$ref reference resolution and in-place merging.
- Optimized property metadata caching and filtering.
- Comprehensive error handling with detailed messages.
- Extensive new tests for primitives, collections, references, and error cases.
- Benchmarks for serialization, deserialization, and merge scenarios.
SignalR infrastructure improvements:

New test and benchmark infrastructure for SignalR:
- Shared test models and data factories for DTOs, primitives, and complex graphs.
- In-memory, dependency-free SignalR client/hub for round-trip testing.
- Exhaustive test suites for message processing, method invocation, and edge cases (including prior production bugs with Task<T>).
