pub const MAX_SYMBOL_LEN: usize = 160;Expand description
Defensive user-input cap for MARKET.CODE shorthand strings.
C++ stores market-state and trade code buffers in fixed char arrays
(charArr64 / szCode[32] in the audited paths). Keep Rust’s public
shorthand cap comfortably above all observed legitimate derivatives, while
rejecting pathological payloads before REST/MCP/CLI normalization allocates
or forwards them.
