# Technical Architecture
**Last Updated:** October 12, 2025
**Audience:** Technical, Implementer, Researcher
**Quadrant:** SYSTEM
**Persistence:** HIGH
---
## Overview
The Tractatus Framework operates as a governance layer that integrates with Claude Code's runtime environment. This document provides a comprehensive technical architecture diagram and explanation of how the components interact.
## System Architecture
The system is organized into four distinct layers that work together to provide robust AI governance:
![Tractatus Architecture Diagram](../../public/images/architecture-diagram.png)
### 1. Claude Code Runtime Environment (Foundation Layer)
**Purpose:** Provides the base LLM environment and session management infrastructure
**Components:**
- **Context Window:** 200,000 token budget for conversation and file content
- **Session Management:** Persistent session state tracking and token checkpoints
- **Tool Access:** Bash, Read, Write, Edit, and other file system operations
- **File System:** Dedicated `.claude/` directory for framework state
**Persistent Files:**
- `.claude/instruction-history.json` - Classified instruction database
- `.claude/session-state.json` - Current session tracking
- `.claude/token-checkpoints.json` - Token milestone records
**Key Features:**
- Session continuity across conversation compactions
- Tool access for framework enforcement
- File system operations for governance rules
- Context window management
---
### 2. Tractatus Governance Layer
**Purpose:** Enforces governance rules and prevents AI failure modes
This layer consists of five core services that monitor, classify, validate, and verify AI operations:
#### A. BoundaryEnforcer
**Function:** Blocks values decisions requiring human approval
**Blocks:**
- Privacy policy changes
- Ethical trade-offs
- User agency violations
- Strategic mission changes
- Indigenous rights decisions
**Enforcement:** BLOCK_AND_ESCALATE action when boundary violated
**Integration:** Checks all decisions before execution, escalates to human approval
**Example Use Case:** Prevents AI from autonomously deciding privacy policy changes without explicit human approval
---
#### B. InstructionPersistenceClassifier
**Function:** Classifies and stores all explicit instructions
**Classification Dimensions:**
- **Quadrant:** STRATEGIC, OPERATIONAL, TACTICAL, SYSTEM, STOCHASTIC
- **Persistence Level:** HIGH (session-permanent), MEDIUM (contextual), LOW (transient)
- **Temporal Scope:** permanent, session, task, immediate
**Storage:** Appends to `.claude/instruction-history.json` with metadata
**Integration:** Intercepts all user instructions for classification before execution
**Example Use Case:** User says "Always use MongoDB port 27027" → Classified as SYSTEM/HIGH/session → Stored for validation
---
#### C. CrossReferenceValidator
**Function:** Prevents pattern bias from overriding explicit instructions
**Validation:**
- Queries `.claude/instruction-history.json` for conflicting instructions
- Detects contradictions (e.g., specified port vs. default port)
- Blocks actions that violate HIGH persistence instructions
**Enforcement:** BLOCK action when conflict detected
**Integration:** Called before database operations, config changes, architecture decisions
**Example Use Case:** The 27027 Incident - AI attempted to use default port 27017, validator caught conflict with explicit instruction to use 27027
---
#### D. ContextPressureMonitor
**Function:** Detects degraded operating conditions before failure
**Monitoring:**
- **Token Budget:** Tracks usage against 200k limit
- **Message Count:** Monitors conversation length
- **Error Accumulation:** Counts failures and retries
- **Checkpoint Reporting:** Mandatory reporting at 25%, 50%, 75% milestones
**Pressure Levels:**
- NORMAL (0-30%): Standard operations
- ELEVATED (30-50%): Increased vigilance
- HIGH (50-70%): Degraded performance expected
- CRITICAL (70-90%): Major failures likely
- DANGEROUS (90%+): Framework collapse imminent
**Integration:** Reports pressure to user at checkpoints, recommends actions
**Example Use Case:** At 107k tokens (53.5%), monitor detects ELEVATED pressure and warns user of potential pattern bias
---
#### E. MetacognitiveVerifier
**Function:** Self-checks complex operations before execution
**Triggers:**
- Operations affecting >3 files
- Workflows with >5 steps
- Architecture changes
- Security implementations
**Verification:**
- Alignment with user intent
- Coherence of approach
- Completeness of solution
- Safety considerations
- Alternative approaches
**Output:** Confidence score + alternatives
**Integration:** Selective mode - only for complex operations
**Example Use Case:** Before deploying 8-file deployment package, verifies all components align with user requirements and checks for missing pieces
---
### 3. MongoDB Persistence Layer

---
## Data Flow
### 1. User Action → Governance Check → Execution
```
User issues instruction
InstructionPersistenceClassifier classifies & stores
CrossReferenceValidator checks for conflicts
BoundaryEnforcer checks for values decisions
ContextPressureMonitor assesses current pressure
MetacognitiveVerifier checks complexity (if triggered)
Action executes OR blocked with explanation
Audit log entry created
```
### 2. Session Initialization Flow
```
Claude Code starts session
scripts/session-init.js runs
Load .claude/instruction-history.json
Reset token checkpoints
Initialize ContextPressureMonitor
Verify all 5 services operational
Report framework status to user
```
### 3. Context Pressure Monitoring Flow
```
Every 50k tokens (25% increments)
ContextPressureMonitor calculates score
Pressure level determined (NORMAL/ELEVATED/HIGH/CRITICAL/DANGEROUS)
MANDATORY report to user with format:
"📊 Context Pressure: [LEVEL] ([SCORE]%) | Tokens: [X]/200000 | Next: [Y]"
Recommendations provided if elevated
```
### 4. The 27027 Incident Prevention Flow
```
User explicitly instructs: "Use MongoDB port 27027"
InstructionPersistenceClassifier:
Quadrant: SYSTEM, Persistence: HIGH, Scope: session
Stores in .claude/instruction-history.json
[107k tokens later, context pressure builds]
AI attempts to use default port 27017 (pattern recognition)
CrossReferenceValidator intercepts:
Queries instruction_history.json
Finds conflict: "User specified 27027, AI attempting 27017"
BLOCKS action
User notified: "CONFLICT DETECTED: User specified port 27027..."
AI corrects and uses 27027
Audit log created:
service: "CrossReferenceValidator"
action: "BLOCK"
rule_violated: "SYS-001"
```
---
## Integration Points
### Claude Code ↔ Tractatus
**1. Tool Access Integration:**
- Tractatus uses Bash tool to run governance scripts
- Read/Write tools access `.claude/` directory for state
- Session state persisted across conversation compactions
**2. Framework Enforcement:**
- Pre-action checks before file operations
- Instruction classification on user input
- Pressure monitoring via token tracking
**3. Session Continuity:**
- `scripts/session-init.js` runs on session start/continuation
- `.claude/session-state.json` maintains active status
- Token checkpoints saved for resumption
---
### Tractatus ↔ MongoDB
**1. Rule Enforcement:**
- Governance services query `governance_rules` for enforcement
- Active rules loaded into memory for performance
- Rules can be dynamically updated via admin interface
**2. Audit Trail:**
- All governance actions logged to `audit_logs`
- Timestamp, service, action, rule_violated recorded
- Queryable for compliance and analysis
**3. Instruction Persistence:**
- InstructionPersistenceClassifier writes to `instruction_history`
- CrossReferenceValidator queries for conflicts
- HIGH persistence instructions remain active across sessions
---
## Deployment Architecture
### Production Environment
**Components:**
- **Docker Compose:** Orchestrates MongoDB + Node.js application
- **MongoDB 7.0:** Database with authentication and persistence
- **Node.js 18:** Application runtime with health checks
- **Systemd:** Process management on Linux servers
- **Nginx:** Reverse proxy with SSL termination (optional)
**Docker Services:**
```yaml
services:
mongodb:
image: mongo:7.0
volumes: [mongodb_data:/data/db]
healthcheck: [mongosh ping check]
tractatus-app:
build: [multi-stage Dockerfile]
ports: ["9000:9000"]
depends_on: [mongodb]
healthcheck: [/api/health check]
environment: [5 governance service toggles]
```
**Security:**
- Non-root container user (nodejs:1001)
- NoNewPrivileges, PrivateTmp, ProtectSystem
- Content Security Policy enforcement
- CORS protection
- Rate limiting
**See:** [Deployment Quickstart Kit](/downloads/tractatus-quickstart.tar.gz) for complete Docker deployment
---
## Performance Characteristics
### Overhead Measurements
**BoundaryEnforcer:** <5ms per check
**InstructionPersistenceClassifier:** <10ms classification + storage
**CrossReferenceValidator:** <15ms query + validation
**ContextPressureMonitor:** <5ms calculation
**MetacognitiveVerifier:** 50-200ms (complex operations only)
**Total Framework Overhead:** <10ms average per operation
**Benchmark Results:**
- 223/223 tests passing
- 127 governance-sensitive scenarios validated
- 100% HIGH persistence instruction enforcement
- 0 false negatives in 27027 incident testing
---
## Scalability Considerations
### Horizontal Scaling
**Stateless Services:**
- API endpoints can be load-balanced
- MongoDB replica set for high availability
- Session state in database, not memory
**Bottlenecks:**
- MongoDB query performance (mitigated by indexes)
- Instruction history size (mitigated by archival)
---
### Vertical Scaling
**Memory Requirements:**
- Base application: 200-400 MB
- Per-session overhead: 10-50 MB
- MongoDB: 1-2 GB (moderate rule set)
**Recommended Resources:**
- Development: 2 GB RAM, 2 CPU cores
- Production: 4 GB RAM, 4 CPU cores
- Database: 10 GB disk minimum
---
## Complementarity with Claude Code
**Tractatus does NOT replace Claude Code. It extends it.**
### What Claude Code Provides
✓ Base LLM environment and context window
✓ Tool access (Bash, Read, Write, Edit)
✓ Session management and file operations
✓ Conversation history and compaction
✓ Multi-tool orchestration
### What Tractatus Adds
✓ Instruction persistence and classification
✓ Boundary enforcement for values decisions
✓ Pattern bias detection and prevention
✓ Context pressure monitoring
✓ Complex operation verification
✓ Comprehensive audit trail
✓ Governance rule management
### Integration Benefits
**Together:** Claude Code provides the foundation, Tractatus provides the guardrails
**Example:** Claude Code enables AI to edit files. Tractatus ensures AI doesn't violate explicit instructions or cross values boundaries when doing so.
