Architecture

CKC implements a revolutionary pure tag-centered architecture:

• Cognitive Load Zero: Eliminates category decision fatigue
• 7-Dimensional Classification: Multi-layer tag system for precise organization
• Automated Intelligence: Pattern-matching content understanding
• State-Based Workflow: Organization by lifecycle, not content type
• Dynamic Discovery: Cross-dimensional knowledge search
• Obsidian Enhancement: Transform basic vaults → intelligent systems

Pure Tag-Centered vs Traditional

❌ Traditional Category-Based Problems

├── prompts/          # "Is this a prompt or template?"
├── code/             # "Code snippet or tool?"
├── concepts/         # "Concept or best practice?"
└── misc/             # Catch-all confusion

Issues:

• Decision fatigue: Which category?
• Rigid boundaries: Content doesn't fit neatly
• Poor discoverability: Single-dimension search
• Maintenance overhead: Moving files between categories

✅ Pure Tag-Centered Solution

├── _system/          # System files and templates
├── inbox/            # Unprocessed items (workflow state)
├── active/           # Currently working (activity state)
├── archive/          # Deprecated/old (lifecycle state)
└── knowledge/        # Mature content (90% of files)
    └── Dynamic discovery through enhanced multi-layer tags

Benefits:

• 🧠 Cognitive Load Reduction: No "which category?" decisions
• 🔍 Multi-Dimensional Discovery: Search across tech, domain, team
• 📈 Scalable Organization: Tags evolve with your knowledge
• ⚡ Flexible Workflow: State-based, not content-based organization
• 🔗 Rich Relationships: Multi-project, multi-domain connections
