Refactored AcBinarySourceGenerator to use RefAwareEmitPredicate for all ref-handling switch decisions, ensuring child property ref-marker logic is based solely on child compile-time flags. Fixed deserialization drift when parent disables ref-handling but child enables it. Added regression tests and new test models to verify correct round-trip behavior for duplicate child references in collections and dictionaries. Improved XML docs and updated conventions for summary tags. Added SGen string round-trip tests for medium UTF-8/ASCII cases.
Refactored the benchmark and test data infrastructure to use generic, type-safe, and multi-variant models. Introduced generic base classes for the test data hierarchy and factories, with closing-generic aliases for _All_True and _All_False families. Benchmarks now select the correct test data variant per serializer options, and all serializers are generic over the order type. Output and result reporting now include the CLR type name for clarity. Centralized string property handling and improved documentation throughout.
Refactor tests to use _All_True model types throughout
Replaced all usages of legacy test model types (e.g., TestOrder, TestOrderItem, SharedTag, etc.) with new, feature-complete _All_True variants across SignalR test infrastructure, data sources, and service handlers. Updated all generic constraints, method signatures, and test data to use the new types. Added SharedTestBaseModels.cs and SharedTestOrderModels.cs to define abstract bases and concrete _All_True models with full serialization attributes. This enables more thorough and realistic serialization/deserialization testing and future extensibility.
- Add overflow/corruption guards to string (de)serialization (writer/reader now throw on invalid lengths)
- Remove dead string serialization methods per BINARY_TODO.md audit
- Update BINARY_TODO.md with closure/resolution for H2Q6, O7G2, V4N5, and related entries
- Add MaxStringCharLength constant and update marker reservations in BinaryTypeCode
- Simplify string cache ASCII verification in deserializer
- Add SGen/Runtime round-trip compatibility tests for large/deep data
- Minor code modernization and style improvements
