Coding Harness

C++ Style

• Use the repository .clang-format.
• Keep two-space indentation, attached braces, and the 80-column limit.
• Keep files ASCII unless existing text requires another character set.
• Put public API in namespace vbvx.

Packet Header Rules

• Preserve packed wire-header layout and related static_asserts.
• Treat on-wire numeric fields as network byte order.
• Use autoswap, helper accessors, and std::to_underlying for enum conversions.
• Before changing header layout, verify size, alignment, byte order, and tests for the affected wire format.

Test Rules

• Tests use GoogleTest through CMake FetchContent.
• Add new test files to tests/CMakeLists.txt.
• Prefer focused tests that construct raw byte arrays in wire order, then assert BufferView or HeaderView behavior.
• Follow TEST(ComponentTest, ScenarioName).
• Cover truncated buffers, invalid protocol combinations, and successful parsing paths for changed packet logic.
