- Add BINARY_FORMAT.md: full AcBinary wire format spec (markers, encoding, options, protocol, interactions)
- Reference BINARY_FORMAT.md from GLOSSARY.md, Binaries/README.md, and Serializers/Binaries/README.md; add new glossary terms
- Clarify and expand config options tables to match new doc
- Add/clarify LLM maintenance rules: always sync .md files with code, auto-fix discrepancies
- Update root README.md: AyCode.Core targets .NET 9, not 10; stress doc/code sync
- Add code reuse and doc sync conventions to copilot-instructions.md and CONVENTIONS.md
- Add docs/ folder and BINARY_FORMAT.md to solution as Solution Items
- Minor clarifications and cross-links in ARCHITECTURE.md and other docs
- Introduced `.github/copilot-instructions.md` as the single source of truth for domain rules, conventions, and pitfalls in each solution.
- Added `CLAUDE.md` to guide Claude to read domain rules, glossary, and README before code generation.
- Updated all solution and project `README.md` files to document project purpose, structure, key files, and LLM context (Copilot/Claude/Cursor).
- Added or revised `docs/ARCHITECTURE.md`, `docs/CONVENTIONS.md`, and `docs/GLOSSARY.md` to clarify dependency graphs, naming, patterns, and terminology.
- For FruitBankHybridApp, added `docs/SCHEMA.md` (Toon format) and expanded the glossary with business/measurement terms and common traps.
- Updated all subfolder READMEs to list key files, conventions, and LLM maintenance notes.
- Ensured all documentation is cross-referenced, up-to-date, and includes explicit instructions for LLMs to keep docs in sync with code and avoid suggesting removal/rollback as a solution.
- Standardized documentation and onboarding for maintainability and LLM/code quality across all solutions.
Updated test and benchmark project dependencies to latest versions (BenchmarkDotNet, coverlet.collector, MSTest, etc.). Reformatted source generator project references for consistency. Commented out most AcBinary benchmark variants in Program.cs, leaving only FastMode+Default enabled. Significantly expanded README with detailed architecture, file descriptions, and configuration for each serializer subfolder. Added LLM maintenance notes to ensure documentation stays in sync with code changes.
Major overhaul of JSON serialization/deserialization:
- 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.
- Direct support for Dictionary<TKey, TValue> and improved collection handling.
- 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:
- Refactored AcSignalRClientBase/AcWebSignalRHubBase for testability (virtual methods, test constructors).
- Added SignalRRequestModelPool for efficient request/response tracking.
- Improved parameter deserialization and IdMessage handling.
- New tags (PingTag, EchoTag) for SignalR messaging.
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>).
- Benchmarks for SignalR serialization, deserialization, and round-trip performance.
Other changes:
- Improved TaskHelper.WaitTo/WaitToAsync with more accurate polling and cancellation support.
- ExtensionMethods.InvokeMethod now properly unwraps Task/ValueTask results.
- General code cleanup, improved comments, and removal of obsolete code.
- Project references updated for shared test/benchmark infrastructure.
These changes deliver a robust, high-performance, and fully tested JSON/SignalR (de)serialization system, ready for production and advanced testing scenarios.
