reference, committed verified 2026-10-16 bootstrap f1e5c15

Every message in the Option area: its opcode, direction, how far it is verified, and its fields.

This grouping comes from where the declarations sit today. It claims nothing about what these messages do, and it changes when the client's areas are settled.

Note

Generated from the message declarations at bootstrap f1e5c15 by Tools/NexusTomorrow.ProtocolReference. Don't edit it by hand: change the declaration's documentation and regenerate.
