feat: technical architecture diagram with comprehensive documentation (Task 8)
Complete system architecture visualization showing Claude Code + Tractatus
integration across 4 layers: API/Web, Governance, Persistence, and Runtime.
**Diagram Files:**
1. architecture-diagram.svg (15KB)
- Scalable vector format for web and documentation
- 4-layer visualization with color-coded components
- Data flow arrows showing integration points
- Professional design suitable for research papers
2. architecture-diagram.png (581KB)
- High-resolution 2400x2000 raster format
- Generated via Inkscape from SVG
- Suitable for presentations and print materials
3. architecture-diagram.mmd
- Mermaid diagram for markdown embedding
- Supports dynamic rendering in documentation
- Version control friendly text format
**Documentation:**
4. docs/markdown/technical-architecture.md (18KB)
- Comprehensive technical architecture guide
- Layer-by-layer component descriptions
- Integration points and data flows
- Performance characteristics (<10ms overhead)
- Deployment architecture (Docker/systemd)
- Complementarity with Claude Code explanation
5. public/downloads/technical-architecture-diagram.pdf
- Generated from markdown with embedded diagram
- Complete documentation in portable format
- Suitable for offline reading and distribution
**Implementer Page Integration:**
6. public/implementer.html
- Added "System Architecture" section after Deployment Quickstart
- Full-width diagram display with shadow effects
- Three download buttons: SVG, PNG (High-Res), PDF
- 4-card layer breakdown (API → Governance → Persistence → Runtime)
- 3-point integration explanation with numbered badges
- Professional color scheme matching brand (purple/green/yellow/blue)
**Architecture Layers:**
Layer 4 - API & Web Interface:
- Demo endpoints (/api/demo/*)
- Admin dashboard
- Documentation system
- Blog with AI curation
Layer 3 - Tractatus Governance:
- BoundaryEnforcer (values decisions)
- InstructionPersistenceClassifier (classification)
- CrossReferenceValidator (pattern bias prevention)
- ContextPressureMonitor (degradation detection)
- MetacognitiveVerifier (complex operation verification)
Layer 2 - MongoDB Persistence:
- governance_rules collection (rule storage with indexes)
- audit_logs collection (compliance trail)
- session_state collection (pressure tracking)
- instruction_history collection (cross-reference validation)
Layer 1 - Claude Code Runtime:
- Base LLM environment (200k context window)
- Session management (persistent state)
- Tool access (Bash, Read, Write, Edit)
- File system operations (.claude/ directory)
**Key Integration Points:**
1. Pre-Action Checks:
- All actions validated against governance rules
- BLOCK or ALLOW with explanation
- Audit log entry created
2. Instruction Persistence:
- User instructions classified (quadrant, persistence, scope)
- Stored in .claude/instruction-history.json + MongoDB
- Cross-referenced before conflicting actions
3. Context Pressure Monitoring:
- Real-time pressure calculation (tokens, messages, errors)
- Mandatory checkpoint reporting (50k, 100k, 150k)
- Early warning system for degradation
**The 27027 Incident Prevention Flow:**
User: "Use MongoDB port 27027"
→ Classifier: SYSTEM/HIGH/session
→ Stored in instruction_history
[107k tokens later, pressure builds]
AI attempts: port 27017 (pattern recognition)
→ CrossReferenceValidator: CONFLICT DETECTED
→ Action BLOCKED, user notified
→ AI corrects to 27027
→ Audit log created
**Deployment:**
✅ Deployed to production:
- SVG/PNG diagrams to /public/images/
- PDF to /public/downloads/
- Markdown docs to /docs/markdown/
- Updated implementer.html with diagram section
**Roadmap Progress:**
Phase 2, Week 3, Task 8: Technical Architecture Diagram - COMPLETED
Priority: High | Effort: 4-6 hours | Status: ✅ Done
**Success Criteria Met:**
✓ Clear, professional diagram explaining complementarity with Claude Code
✓ High-resolution exports (SVG, PNG, PDF)
✓ Comprehensive technical documentation
✓ Integrated into implementer page
✓ Multiple format downloads available
✓ Layer-by-layer component breakdown
✓ Data flow visualization
✓ Performance metrics documented
Next: Task 9 - Video Walkthrough (Week 3, 2-3 days)
