--- Tree Navigator - Directory tree visualization and export tool
+-- Tree Navigator — High-Assurance Directory Visualization.
+--
+-- This Ada 2022 module implements the primary logic for the `tn` utility.
+-- It provides a cross-platform interface for navigating physical directory 
+-- trees and exporting them to structured text files.
+--
+-- DESIGN PILLARS:
+-- 1. ADABILITY: Leveraging Ada's strong typing and formal verification 
+--    capabilities for filesystem interactions.
+-- 2. DUAL-MODE: Supports both interactive terminal navigation and 
+--    unattended batch exports.
+-- 3. FILTERING: Granular exclusion rules for directories (e.g. target, node_modules).
