Refactor SignalR protocol type resolution logic
Removed SignalParams.SignalDataType and migrated type resolution to protocol headers using new WriteHeader/ReadHeader extensibility hooks. AyCodeBinaryHubProtocol now writes and reads the concrete data argument type in the message header, enabling correct deserialization of object-typed arguments. Updated AcBinaryHubProtocol to support header context and made relevant helpers protected. Cleaned up legacy SignalDataType logic and improved documentation.
Enhances debugging of custom binary serialization/deserialization in SignalR by introducing DiagnosticLogger hooks in both AcBinaryDeserializer and AcBinaryHubProtocol. Adds DEBUG-only verification methods to compare array-based and multi-segment deserialization, as well as IBufferWriter and byte[] serialization outputs, logging mismatches for easier bug isolation. Diagnostic loggers are automatically integrated with the hub and client loggers. Also includes extra debug output and a commented workaround for a known serialization issue. Diagnostics are opt-in and only active in DEBUG builds.
- Change OnReceiveMessage signature to use `object data` (was `SignalData`), enabling type-aware and raw byte[] payloads.
- Implement three-path argument deserialization: byte[] fast-path, IsRawBytesData, and eager typed deserialization via SignalDataType.
- Add SignalDataType and IsRawBytesData fields to SignalParams for protocol guidance.
- Write path now uses AcBinarySerializer zero-copy to pipe; byte[] uses fast-path.
- SequenceBinaryInput now dynamically sizes scratch buffer for large cross-segment reads.
- Deserializer now advances segments before throwing end-of-buffer, improving multi-segment support.
- Set client logging to Debug for better diagnostics.
- Update all docs and markdown to reflect new protocol, dispatch model, and field semantics.
- AyCodeBinaryHubProtocol is now an empty derived class for registration/future hooks; SignalData is no longer the primary payload type.
- SignalResponseDataMessage is now an internal DTO with RawResponseData as object? (typed or byte[]), and GetResponseData<T>() is a direct cast.
Implements a high-performance raw byte[] protocol path for SignalR DataSource GetAll/LoadDataSource, using a new IsRawBytesData flag in SignalParams. When enabled, the server pre-serializes response data and sends it as a byte array, which the protocol passes through without further (de)serialization. The client receives the raw bytes and deserializes as needed, avoiding double serialization/deserialization and improving performance for large payloads.
Adds SerializerType selection to DataSource, propagates SignalParams through hub and protocol layers, and updates client/server/test code to support the new path. Also includes diagnostics flags for binary serialization debugging and fixes for multi-segment buffer handling.
Major overhaul for SignalR response pipeline:
- All deserialization now uses byte[] (offset/length) for zero-copy, allocation-free operation; all span/memory overloads removed.
- SignalR protocol sends (signalParams, object) directly; SignalData envelope and related logic removed.
- Server sets SignalParams.SignalDataType so protocol deserializes to the correct runtime type on the client.
- SignalResponseDataMessage now only used for client request/response tracking and stream path; RawResponseData holds the actual object.
- All extension methods, helpers, and infrastructure updated to use new byte[]-based APIs.
- AcSignalRDataSource and all test/benchmark code updated for new object flow.
- Removes all diagnostics, logging, and error handling related to binary envelopes.
- Enables true zero-copy, type-safe, allocation-free SignalR response handling.
Major protocol refactor: all byte[] payloads in SignalR hub/client interfaces, plumbing, and DTOs are now wrapped in SignalData, a disposable, ArrayPool-backed type with Span access. Introduces AyCodeBinaryHubProtocol (derived from AcBinaryHubProtocol) to rent pooled buffers for SignalData on receive. All message signatures, diagnostics, and serialization logic updated. Documentation and tests revised to reflect SignalData usage. Enables zero-copy, low-GC, high-performance binary messaging for large payloads.
Major protocol/API change: replace SignalReceiveParams with SignalParams everywhere. SignalParams now carries packed method parameters as a single byte[] and provides SetParameterValues/GetParameterValues for type-safe packing/unpacking. All hub/client interfaces, method signatures, and dispatch logic updated. Legacy parameter serialization helpers removed; all parameter logic is encapsulated in SignalParams. Documentation and tests updated to reflect new wire format and flow. This unifies parameter handling, clarifies the protocol, and enables robust, extensible type-guided serialization. Breaking change.
Replaces legacy JSON-in-Binary parameter envelopes with a length-prefixed, per-parameter binary format for all client→server calls. Introduces SerializeParametersToBinary and DeserializeParametersFromBinary for type-safe, zero-copy parameter handling. Marks IdMessage, SignalPostJsonDataMessage, and related wrappers as obsolete. Updates all client CRUD/messaging helpers and server-side dispatch to use object[] binary serialization. Adds DataSerializerType to SignalReceiveParams for response format indication. Updates tests and documentation to reflect new protocol. BREAKING CHANGE: not compatible with previous JSON-in-Binary clients/servers.
Major protocol update: OnReceiveMessage now takes metadata (SignalReceiveParams) and payload (byte[]) as separate hub arguments, not a single envelope. Metadata is AcBinary-serialized; payload uses protocol fast-path. Updated all client/server code, interfaces, and docs. Added ISignalParams and SignalReceiveParams types. Improved AcBinaryHubProtocol diagnostics and made byte[] fast-path more robust. This enables clearer, more debuggable, and future-proof SignalR binary messaging.

The hub now fills in missing arguments with default values when not provided, and throws if required parameters are missing. Added comprehensive tests for default parameter handling, a new handler method for testing, and a tag constant. Also improved code style with C# pattern matching and made UseStringCaching immutable.
Replaced explicit 'int' declarations with 'var' for local variables in for loops and variable initializations. This improves code conciseness and maintains consistency without altering functionality.
Changed the log level from Debug to Warning when a dynamic method
is not found for a given tag, making these events more visible
in the logs and easier to monitor.
Introduces detailed, opt-in diagnostic logging for binary serialization and deserialization in SignalR server and client code. Adds type and binary-level diagnostics, including hex dumps and header parsing, to aid debugging of protocol and type mismatches. Improves string hash function in the binary deserializer to avoid collisions. Diagnostics are consistent and structured, and can be enabled independently on server, client, and response message classes. No impact on normal operation unless diagnostics are enabled.

and Brotli-compressed JSON, managed via a new SignalRSerializationHelper.
Custom stream classes and MessagePack attributes are removed.
API is now consistent, type-safe, and easier to maintain.
Test code and all message handling updated to use the new model.
Major performance improvements for SignalR message transport:
