Common Tasks

Task 1: Version Number Update (v2.0.0)

Trigger: Version bump to v2.0.0

# Detect version change
OLD_VERSION="v1.8.1"
NEW_VERSION="v2.0.0"

# Update all references
find docs/ -name "*.md" -type f -exec sed -i '' "s/$OLD_VERSION/$NEW_VERSION/g" {} \;

# Files typically affected:
# - ARCHITECTURE_v1.8.1.md → rename to ARCHITECTURE_v2.0.0.md
# - USER_GUIDE.md (version references)
# - QUICKSTART.md (version in examples)
# - MIGRATION_v2.0.0.md (new file)
# - CLAUDE.md (version history)

Automation:

on_version_bump:
  1. Grep all .md files for old version
  2. Replace with new version (v2.0.0)
  3. Rename ARCHITECTURE_v*.md if needed
  4. Create MIGRATION_v2.0.0.md from template
  5. Update CLAUDE.md version history
  6. Commit: "docs: update version references to v2.0.0"

Task 2: 3-Branch Architecture Documentation

New sections for ARCHITECTURE_v2.0.0.md:

## 3-Branch Parallel Detection Pipeline

### Overview

Input → Validator → 3-Branch Executor (PARALLEL) ├── Branch A: Heuristics (:5005) - 30% ├── Branch B: Semantic (:5006) - 35% └── Branch C: LLM Guard (:8000) - 35% ↓ Arbiter v2 → Decision → PII → Output

### Branch Specifications

| Branch | Service | Port | Weight | Timeout | Function |
|--------|---------|------|--------|---------|----------|
| A | heuristics-service | 5005 | 30% | 1000ms | Pattern matching |
| B | semantic-service | 5006 | 35% | 2000ms | Embedding similarity |
| C | prompt-guard-api | 8000 | 35% | 3000ms | LLM validation |

### Arbiter v2 Decision Logic
- **BLOCK:** Weighted score >= 70
- **SANITIZE:** Weighted score 30-69
- **ALLOW:** Weighted score < 30

Task 3: API Documentation Generation

Trigger: New endpoint added to Express backend

// Source: services/web-ui/backend/src/server.ts
// New v2.0.0 endpoints:

// Branch health check
app.get('/api/health/branches', authMiddleware, branchHealthHandler);

// Branch analysis proxies
app.post('/api/analyze/heuristics', authMiddleware, heuristicsHandler);
app.post('/api/analyze/semantic', authMiddleware, semanticHandler);

// Branch metrics
app.get('/api/metrics/branches', authMiddleware, branchMetricsHandler);

Generate API.md section:

## Branch Services API (v2.0.0)

### GET /api/health/branches
Check health status of all 3 branch detection services.

**Response:**
```json
{
  "branch_a": { "name": "Heuristics", "port": 5005, "healthy": true },
  "branch_b": { "name": "Semantic", "port": 5006, "healthy": true },
  "branch_c": { "name": "LLM Guard", "port": 8000, "healthy": true }
}

POST /api/analyze/heuristics

Test heuristics service (Branch A) directly.

Request:

{
  "text": "input to analyze",
  "request_id": "test-123"
}

### Task 4: Config Variable Documentation

**Trigger:** New variable added to variables.json

```json
// v2.0.0 new variables
{
  "name": "branch_a_weight",
  "key": "branch_a_weight",
  "type": "number",
  "default": 0.30,
  "description": "Heuristics branch weight in arbiter fusion (0.0-1.0)",
  "group": "3-Branch Detection"
},
{
  "name": "arbiter_block_threshold",
  "key": "arbiter_block_threshold",
  "type": "number",
  "default": 70,
  "description": "Minimum weighted score for BLOCK decision",
  "group": "3-Branch Detection"
}

Task 5: Migration Guide (v1.x → v2.0.0)

Template: docs/MIGRATION_v2.0.0.md

# Migration Guide: v1.8.1 → v2.0.0

## Breaking Changes
- [ ] Architecture: 40-node sequential → 24-node 3-branch parallel
- [ ] Config: rules.config.json removed (merged into unified_config.json)
- [ ] Services: 2 new containers (heuristics-service, semantic-service)
- [ ] ClickHouse schema: Add branch columns

## Database Migrations
```sql
-- Run in ClickHouse
ALTER TABLE n8n_logs.events_processed
  ADD COLUMN branch_a_score Float32 DEFAULT 0,
  ADD COLUMN branch_b_score Float32 DEFAULT 0,
  ADD COLUMN branch_c_score Float32 DEFAULT 0,
  ADD COLUMN arbiter_decision String DEFAULT '';

Service Updates

# Pull new images
docker-compose pull

# Start new services
docker-compose up -d heuristics-service semantic-service

Workflow Import

1. Export old workflow from n8n
2. Import: services/workflow/workflows/Vigil Guard v2.0.0.json
3. Verify 24 nodes visible

Verification

• Branch health: curl http://localhost/api/health/branches
• Arbiter decision in logs: SELECT arbiter_decision FROM events_processed LIMIT 1
• All 11 services running: ./scripts/status.sh

Troubleshooting

Issue: Docs out of sync with v2.0.0 code

Diagnosis:

# Check for old version references
grep -rn "v1\.[0-9]\+\.[0-9]\+" docs/ | grep -v "Binary"
grep -rn "rules.config.json" docs/  # Should be minimal
grep -rn "40-node\|40 node" docs/  # Should be 0

Solution:

# Update to v2.0.0
OLD="v1.8.1"
NEW="v2.0.0"
find docs/ -name "*.md" -exec sed -i '' "s/$OLD/$NEW/g" {} \;

# Remove rules.config.json references
# Replace with unified_config.json

# Update architecture references
# Replace "40-node" with "24-node 3-branch"

Quick Reference

# Check version consistency
grep -rn "v[0-9]\+\.[0-9]\+\.[0-9]\+" docs/ | sort -u

# Validate links
./scripts/validate-doc-links.sh

# Generate API docs
./scripts/generate-api-docs.sh

# Sync config docs
./scripts/sync-config-docs.js
