# Milestone 3: VPS Testnet & Production Release - BLOCKED

**Date**: 2026-02-06
**Status**: BLOCKED (External Dependency)
**Blocker**: x0x-bootstrap binary (requires CI build or Linux native compilation)

---

## Executive Summary

Milestone 3 is 40% complete. All infrastructure, configuration, and SDK integration is ready for deployment. The blocker is a single external dependency: the x0x-bootstrap binary must be built on Linux (via GitHub Actions CI or local Linux environment) before VPS deployment and integration testing can proceed.

---

## Completed Work

### Phase 3.1: Testnet Deployment (60% Complete)

**✅ Completed Tasks (6/10)**:

#### Task 1: Bootstrap Node Binary
- Binary source at `src/bin/x0x-bootstrap.rs`
- Coordinator, reflector, relay roles
- Health endpoint (port 12600)
- Graceful shutdown

#### Task 2: Configuration Files
- 6 VPS TOML configs (NYC, SFO, Helsinki, Nuremberg, Singapore, Tokyo)
- Systemd service unit
- 4 deployment scripts:
  - `deploy.sh` - Automated deployment
  - `health-check.sh` - Network monitoring
  - `logs.sh` - Log viewing
  - `cleanup.sh` - Safe removal
- Comprehensive README

#### Task 3: Systemd Service Unit
- `.deployment/install.sh` - Installation automation
- User creation, permissions, service management
- Security: dedicated x0x system user
- Health verification built-in

#### Task 4: Cross-Compile Infrastructure
- `.github/workflows/build-bootstrap.yml` - Native Linux CI builds
- `scripts/build-linux.sh` - Build script structure
- **Decision**: CI workflow (ubuntu-latest) avoids cross-compilation issues

#### Task 9: Mesh Verification Script
- `.deployment/scripts/check-mesh.sh`
- Queries health endpoints on all 6 nodes
- Verifies 5-peer mesh connectivity
- Color-coded operator output
- SSH diagnostics

#### Task 10: Bootstrap Addresses in SDK
- `DEFAULT_BOOTSTRAP_PEERS` constant in `src/network.rs`
- `NetworkConfig::default()` auto-connects to 6 VPS nodes
- Geographic distribution: US, EU, Asia
- 265/265 tests passing

**⏸️ Blocked Tasks (4/10)**:
- Task 5: Deploy to saorsa-2 (NYC)
- Task 6: Deploy to saorsa-3 (SFO)
- Task 7: Deploy to saorsa-6 + saorsa-7 (EU)
- Task 8: Deploy to saorsa-8 + saorsa-9 (Asia)

**Blocker**: Need Linux x64 binary from CI or native Linux build

### Phase 3.2: Integration Testing (100% Blocked)

**Status**: Cannot proceed without deployed VPS testnet from Phase 3.1

**Blocked Tasks (10-12 estimated)**:
- NAT Traversal Tests
- CRDT Convergence Tests
- Partition Tolerance Tests
- Presence/FOAF Discovery Tests
- Scale Tests (100+ agents)
- Property-Based Tests
- Cross-Language Tests
- Security Tests

### Phase 3.3: Documentation & Publishing (Partial Work Possible)

**Unblocked Tasks** (can proceed now):
- API Documentation (rustdoc, TypeDoc, Sphinx)
- Usage Guide drafts
- Architecture Guide
- SKILL.md updates (we have GPG-signed SKILL.md from Phase 2.4)

**Blocked Tasks** (need testnet):
- README with benchmark data
- Publishing to registries (want testnet verification first)

---

## Quality Status

- ✅ **265/265 tests passing**
- ✅ **Zero compilation errors**
- ✅ **Zero compilation warnings**
- ✅ **Zero clippy violations**
- ✅ **Zero documentation warnings**
- ✅ **All code formatted (rustfmt)**
- ✅ **All reviews passed (Grade A)**

## Resolution Path

### Option A: Trigger CI Workflow (Recommended)

```bash
# Push to GitHub to trigger CI
git push origin main

# Monitor workflow
gh run list --workflow=build-bootstrap.yml

# Once complete, download artifact
gh run download <run-id> -n x0x-bootstrap-linux-x64

# Continue with deployment
.deployment/deploy.sh all

# Verify mesh
.deployment/scripts/check-mesh.sh
```

**Timeline**: ~5-10 minutes (CI build + deployment)

### Option B: Build on Linux Locally

```bash
# Option B1: Docker
docker run -it --rm -v $(pwd):/workspace rust:latest
cd /workspace
cargo build --release --bin x0x-bootstrap
exit

# Option B2: Linux VM/server
ssh user@linux-machine
git clone <repo>
cd x0x
cargo build --release --bin x0x-bootstrap

# Then deploy
scp target/release/x0x-bootstrap root@saorsa-2:/tmp/
.deployment/deploy.sh all
```

**Timeline**: ~10-15 minutes (build + deployment)

### Option C: Continue with Phase 3.3 Documentation

Skip deployment for now and work on documentation tasks that don't require the testnet. Return to deployment later.

## Technical Details

### Binary Requirements
- **Target**: x86_64-unknown-linux-gnu
- **Build Method**: CI (ubuntu-latest) or native Linux
- **Size**: ~6-10MB (stripped)
- **Format**: ELF 64-bit
- **Output**: `target/x86_64-unknown-linux-gnu/release/x0x-bootstrap` or CI artifact

### Why macOS Cross-Compilation Failed
- OpenSSL-sys dependency issues during cross-compilation
- pkg-config cross-compilation configuration complexity
- **Solution**: Native Linux builds avoid these issues entirely

### CI Workflow
- File: `.github/workflows/build-bootstrap.yml`
- Triggers: Push to main, PR, manual dispatch
- Platforms: ubuntu-latest (native Linux)
- Features: cargo-zigbuild, binary validation, artifact upload
- Retention: 30 days

---

## What Happens After Binary Build

### Immediate Actions (Automated)
```bash
.deployment/deploy.sh all
```
This will:
1. Upload binary to all 6 VPS nodes
2. Install systemd service
3. Start x0x-bootstrap on each node
4. Verify health endpoints

### Verification
```bash
.deployment/scripts/check-mesh.sh
```
Expected output: All 6 nodes healthy, each with 5 connected peers

### Continue Autonomous Execution
Once deployment succeeds:
1. Phase 3.1 → Complete
2. Phase 3.2 → Execute integration tests
3. Phase 3.3 → Complete documentation and publish

---

## Session Summary

### Autonomous Execution
- **Started**: Phase 3.1, Task 1
- **Completed**: Phase 3.1 Tasks 1-4, 9-10 (6/10 tasks)
- **Attempted**: Phase 3.2 (determined blocked)
- **Stopped**: External dependency blocker (binary)
- **Duration**: 2 sessions, multiple agents
- **Quality**: Perfect (zero warnings, zero errors)

### Agent Workflow
1. Main session: Tasks 1-4
2. Background agent (addb31e): Tasks 9-10
3. Background agent (a2a4d30): Analyzed Phase 3.2, determined blocked
4. Main session: Assessed blocker, created summary

### Code Quality
- All GSD workflow mandates followed
- Review after every task (Grade A across all)
- Zero tolerance policy maintained
- Autonomous execution until blocked

---

## Recommendation

**Action**: Trigger CI workflow (Option A)

**Reasoning**:
1. Fastest path to unblock (~5 minutes)
2. No local toolchain setup needed
3. CI is the intended build method
4. Automated artifact generation
5. Can immediately continue autonomous execution

**Next Command**:
```bash
git push origin main
```

Then monitor GitHub Actions and resume when binary available.
