pub const MAX_REPORT_LEVELS: usize = 16;Expand description
Cap on the number of levels a DATA header may order a report for
(docs/PROTOCOL.md §6.2, key 10).
A report order is a remote-controlled list, so it needs a cap for the
same reason MAX_LIST_ITEMS exists; 16 is more levels than the level
space defines below the application floor, so it constrains nothing a
sender legitimately wants.
