## 1. Purpose

APEX OS uses a **curated set of tools** — each evaluated, certified, and monitored. This registry serves as:

- **Inventory** — What tools are deployed, their versions, and their purpose
- **Governance** — How tools are evaluated, adopted, and retired
- **Operations** — Container names, ports, and network configuration for each tool
- **Standards** — The quality bar every tool must meet before production deployment

No tool enters production without passing the certification process. No tool remains in production without ongoing maintenance and monitoring.

## 4. Evaluation Criteria

Every tool considered for APEX OS is evaluated against these criteria:

| Criterion | Weight | Description |
|-----------|--------|-------------|
| **Open Source** | High | Open-source strongly preferred. Proprietary only with explicit justification. (Constitution: Open Source First Policy) |
| **Docker Compatible** | Required | Must run in a Docker container via docker-compose. No host-level installations. (Constitution: Law 3) |
| **Active Maintenance** | High | Must have meaningful commits within the last 6 months. Abandoned projects are not accepted. |
| **Security Track Record** | High | No major unpatched CVEs. Supports non-root execution. Supports read-only filesystem where applicable. |
| **Resource Efficiency** | Medium | Must operate within APEX OS resource budget (see §12). Memory and CPU usage measured during sandbox testing. |
| **Integration Capability** | Medium | Must integrate with existing stack (Docker networks, Traefik labels, PostgreSQL, Redis as applicable). |
| **Documentation Quality** | Medium | Must have clear installation, configuration, and API documentation. |
| **Community Size** | Low | Larger communities provide better support and faster bug fixes, but niche tools with excellent quality are acceptable. |

### Evaluation Scoring

| Score | Meaning |
|-------|---------|
| 5 | Exceeds all criteria — ideal fit |
| 4 | Meets all criteria — good fit |
| 3 | Meets most criteria — acceptable with caveats |
| 2 | Meets minimum criteria — significant compromises |
| 1 | Fails critical criteria — not recommended |

**Minimum score for production adoption:** 3 (with documented caveats for any criteria scored below 3)

## 6. Lifecycle Stages

Every tool in APEX OS passes through defined lifecycle stages:

```
Discovery → Evaluation → Sandbox → Testing → Staging → Production → Maintenance → Deprecation → Retirement
```

| Stage | Description | Duration | Exit Criteria |
|-------|-------------|----------|---------------|
| **Discovery** | Tool identified as potential solution | 1-2 days | Research report completed |
| **Evaluation** | Scored against criteria, alternatives compared | 1-3 days | Evaluation matrix completed |
| **Sandbox** | Deployed in isolated Docker network | 1-3 days | Core functionality verified |
| **Testing** | Integration tested with existing stack | 1-3 days | All integrations working |
| **Staging** | Running alongside production (shadow mode) | 1-7 days | 24h+ stability verified |
| **Production** | Live, serving real workloads | Ongoing | Monitoring configured |
| **Maintenance** | Regular updates, monitoring, optimization | Ongoing | Remains healthy and useful |
| **Deprecation** | Replacement identified, migration planned | 1-4 weeks | Data migration complete |
| **Retirement** | Removed from docker-compose, volumes cleaned | 1 day | Registry updated, docs updated |

---

## 7. Security Review Requirements

Every tool must pass a security review before production deployment:

### 7.1 Container Security Checklist
- [ ] **No `--privileged` flag** unless absolutely necessary (with documented justification)
- [ ] **Non-root user** inside container (where the tool supports it)
- [ ] **Read-only filesystem** (`:ro`) for mounts where possible
- [ ] **No direct Docker socket access** — use Docker Socket Proxy if needed
- [ ] **Network isolation** — tool on `apex_apex-net` network only
- [ ] **No unnecessary ports exposed** to host
- [ ] **Health check defined** in docker-compose

### 7.2 Credential Security
- [ ] Credentials passed via environment variables (not command-line arguments)
- [ ] No default passwords remaining
- [ ] Credentials stored in Vaultwarden
- [ ] Credential rotation plan documented

### 7.3 CVE Review
- [ ] Check for known CVEs in the tool and its dependencies
- [ ] Verify the tool's security advisory process
- [ ] Ensure timely patching is feasible

---

## 8. Sandbox Testing Protocol

### 8.1 Sandbox Environment
- Isolated Docker network: `apex-sandbox`
- No access to production data or services
- Separate PostgreSQL database (if needed)
- Resource-limited (CPU and memory caps)

### 8.2 Test Duration
- **Minimum:** 24 hours of continuous operation
- **Recommended:** 72 hours for critical services
- Monitoring for memory leaks, crash loops, and resource creep

### 8.3 Test Checklist
- [ ] Container starts successfully
- [ ] Health check endpoint responds
- [ ] Core functionality works as documented
- [ ] Integration with relevant APEX OS services verified
- [ ] Resource usage within budget (see §12)
- [ ] Logs are structured and meaningful
- [ ] Graceful shutdown (responds to SIGTERM)
- [ ] Recovery after container restart

---

## 9. Promotion Process

To promote a tool from sandbox to production:

1. **Sandbox tests pass** — All checklist items verified
2. **Documentation complete** — Entry prepared for this registry
3. **Monitoring configured** — Grafana dashboard or Prometheus metrics
4. **Engineer (#1) approval** — Technical sign-off
5. **Human CEO approval** — Final approval via Telegram (Constitution Law 6)
6. **Production deployment** — Added to `docker-compose.yml` with proper labels
7. **Registry updated** — This document updated with new tool entry
8. **Team notified** — CEO Agent informed for task assignment updates

---

## 10. Retirement Process

When a tool is no longer needed or has been replaced:

1. **Identify replacement** — Document what replaces this tool (or why it's no longer needed)
2. **Migrate data** — Transfer any data to replacement tool or archive
3. **Update integrations** — Reroute any dependencies to replacement
4. **Remove from docker-compose** — Stop and remove the container
5. **Clean up volumes** — Remove Docker volumes (after confirming backup)
6. **Update documentation** — Mark as retired in this registry
7. **Update monitoring** — Remove Grafana panels and Prometheus targets
8. **Log decision** — Record retirement in `engineer_decisions`

---

## 11. Update Strategy

### 11.1 Version Pinning
- All tools **pin versions** in `docker-compose.yml` where possible
- Use specific tags (e.g., `postgres:16.3`) rather than `latest` for critical services
- `latest` tag acceptable for rapidly-evolving tools with good backward compatibility (e.g., Grafana, n8n)

### 11.2 Update Process
1. **Check release notes** — Review what changed in the new version
2. **Test in sandbox** — Pull new version in isolated environment
3. **Backup current state** — `cp docker-compose.yml docker-compose.yml.backup.*`
4. **Update docker-compose** — Change version tag
5. **Pull and restart** — `docker-compose pull [service] && docker-compose up -d [service]`
6. **Monitor for 15 minutes** — Watch logs and metrics for anomalies
7. **Rollback if needed** — Restore backup and previous image
8. **Log update** — Record in `engineer_decisions`

### 11.3 Update Frequency
| Category | Update Cadence | Rationale |
|----------|---------------|-----------|
| Security patches | Immediate (within 24h) | Security is paramount |
| Bug fixes | Weekly review | Stability improvements |
| Feature updates | Monthly review | New capabilities when stable |
| Major versions | Quarterly review | Thorough testing required |

---

## 12. Resource Budget

### 12.1 Current VPS Specifications
- **Provider:** Hostinger
- **IP:** 62.72.3.145
- **Resources:** Shared VPS (specific specs TBD in audit)

### 12.2 Resource Guidelines
| Category | Guideline |
|----------|-----------|
| New tool idle memory | < 256 MB preferred, < 512 MB acceptable |
| New tool idle CPU | < 5% preferred |
| Total container count | Currently 20 — evaluate need before adding more |
| Disk usage per tool | < 1 GB for application data (excluding logs) |

### 12.3 Resource Monitoring
- Prometheus tracks per-container CPU, memory, and disk I/O
- Grafana Executive Dashboard visualizes resource trends
- Alerts configured for resource threshold breaches
