• Topic Basics, Subscription Models, and Thread Safety
• Packet Packing and Parsing
• Linux Shared-Memory Topic

Current Mainline Scope

This group currently covers three public paths:

• Topic: in-process strongly typed message publish/subscribe
• Topic::Server / Packet: packing and parsing over byte-stream transports such as UART, buses, or network links
• LinuxSharedTopic: Linux host-side cross-process Topics over shared memory

In current mainline, the core Topic contract is strongly typed dispatch, not the older “Topic keeps its own latest cache” model.
