+Gate 14: Monospace Semantic Badging & ASCII Tree Alignment Linter.
+Validates:
+  1. 100% elimination of meaningless '⚡ TEXT Implementation' and '⚡ NONE Implementation'.
+  2. Integrity of content-aware semantic badges:
+     - ⚡ Python 3.12+ / C99 / Assembly Implementation (.dna-label-code)
+     - 📐 Monospace Reference Matrix (.dna-label-matrix)
+     - 🧬 Memory Architecture & Layout (.dna-label-memory)
+     - ⏱️ Execution Trace & State Simulation (.dna-label-trace)
+     - 🌳 Structural Hierarchy & Tree Topology (.dna-label-tree)
+     - 📜 Algorithmic Blueprint (.dna-label-blueprint)
+     - 📋 Technical Specification & Proof (.dna-label-spec)
+  3. Indentation & alignment preservation in ASCII tree diagrams:
+     - Root nodes (e.g. [ Root: X ], [ 50 ], 12, CEO) retain full leading whitespace.
+     - Zero snapping of first-line tree nodes to column 0.
+     - Mathematical geometric centering: Root node center is verified to be
+       within <= 1.0 character cell of the child branch slashes (/ and \\) apex.
