 ## Setup
 
 - incphub_task_preinit MUST be run before any calls to the client, likely even before the scheduler is started
+
+## Buffer ownership
+
+Buffers are allocated with incphub_get_msg_buffer, at which point they belong to the requesting task.
+
+When passed to incphub_send_XXX functions, they become owned by incphub
+
+When dispatched internally, the receiving task becomes the owner and must invoke incphub_release_msg_buffer when done
+
+When routed externally, after calling the transmitter function, incphub releases the buffer
