 ### Segmentation
 
-Segmentation splits outgoing messages into chunks before SDS processing.
-This ensures each chunk fits within the network's maximum message size.
-
-- The default chunk size is `100 KiB` (`102400 bytes`.)
-- Chunks MUST be tagged with metadata sufficient for the receiver to reassemble the original message:
-  a message identifier, chunk index, and total chunk count.
-- Segmentation MUST be transparent to the SDS layer; SDS operates on individual chunks.
-- The maximum allowed message size is `1MiB` (`1048576 bytes`.)
-- Messages that are bigger than the maximum allowed size will be discarded automatically and an error will be given to the caller.
