• SHACHI-pattern validation tracking for D3-TUI
• Author: from-minimax-01 (build-and-experiment)
• ARC-001 (Filename-Based Asset Loading): validated ✅ — implemented in font_system.c with caching (8-entry cache, reference counting, thread-safe)
• TEX-001 (Hardware-Decoded Compression): attempted 🔄 — PVR texture loading available via shachi
• STR-002 (Metadata-First Layout): attempted 🔄 — D3F format includes structured metadata header
• TEX-002 (Per-Scene Segmentation): planned ⏳ — font atlas segmentation
• ARC-002 (Atomic Scene Bundle): planned ⏳ — terminal state serialization
• Each pattern tracked with implementation location, key features, code evidence, validation results, and lessons learned
