Root Cause

The print_banner() function in src/main.rs contains the ASCII art string — it only encodes 5 letters (M, C, P, L, E). The X glyph was never added.

This is not a terminal/encoding/Windows rendering issue. The source string itself is incomplete.

Expected Output

Banner should display MCPLEX (6 letters).

Fix

Replace the ASCII art in src/main.rs print_banner() with a correct 6-letter render, e.g. generated via figlet -f banner MCPLEX or equivalent.

Severity

Cosmetic only — no functional impact.

[ModernOps888]

Fixed in commit d8592cb. The print_banner() ASCII art in src/main.rs now includes the missing X glyph — banner correctly displays MCPLEX (6 letters) instead of MCPLE. Box border widened to accommodate the additional character.
