## Architecture Overview
The StellaOps CI/CD infrastructure uses **Gitea Actions** (GitHub Actions compatible) with a sophisticated multi-tier triggering strategy designed for:
- **Determinism & Reproducibility** - Identical builds across runs
- **Offline-First Operation** - Air-gap compatible pipelines
- **Supply Chain Security** - SLSA Level 2-3 compliance
- **Developer Velocity** - Fast PR feedback with comprehensive nightly testing

## Key Features
### 1. PR-Gating Tests
Required tests that must pass before merge:
- **Unit Tests** - Fast, isolated tests
- **Architecture Tests** - Dependency rule enforcement
- **Contract Tests** - API compatibility
- **Integration Tests** - PostgreSQL integration
- **Security Tests** - Security-focused assertions
- **Golden Tests** - Corpus-based validation
### 2. Determinism Verification
All builds produce identical outputs:
- Binary checksums compared across runs
- UTC timezone enforcement (`TZ: UTC`)
- Stable JSON serialization
- Reproducible SBOM generation
### 3. Supply Chain Security
- **SBOM Generation** - Syft for CycloneDX/SPDX
- **Artifact Signing** - Cosign/Sigstore integration
- **Provenance** - in-toto/DSSE attestations
- **Dependency Scanning** - Automated vulnerability detection
### 4. Rollback Automation
Emergency rollback via `rollback.yml`:
- Target: < 5 minute SLA
- Helm-based deployment rollback
- Health check verification
- Notification integration

## Getting Started
### Running Workflows Locally
```bash
# Run test matrix locally
./devops/scripts/test-local.sh
# Validate compose files
./devops/scripts/validate-compose.sh
# Run a specific test category
./.gitea/scripts/test/run-test-category.sh Unit
```
### Triggering Manual Workflows
```bash
# Via Gitea UI: Actions → Workflow → Run workflow
# Or via API:
curl -X POST \
-H "Authorization: token $GITEA_TOKEN" \
"$GITEA_URL/api/v1/repos/owner/repo/actions/workflows/rollback.yml/dispatches" \
-d '{"ref":"main","inputs":{"environment":"staging","version":"v2025.12.0"}}'
```
### Creating a Release
1. **Module Release:**
```bash
git tag module-authority-v1.2.3
git push origin module-authority-v1.2.3
```
2. **Suite Release:**
```bash
git tag suite-2026.04
git push origin suite-2026.04
```
3. **Bundle Release:**
```bash
git tag v2025.12.1
git push origin v2025.12.1
```
