## Implementation Details

### Workflow Architecture

**Before**: Single monolithic job (~4+ minutes)

**After**: 4 parallel/sequential jobs (~2.5 minutes)

```
┌─────────────┐  ┌─────────────┐
│   Format    │  │   Clippy    │  ← Parallel (40s total)
└──────┬──────┘  └──────┬──────┘
       │                │
       └────────┬───────┘
                ▼
       ┌─────────────┐
       │    Build    │  ← Sequential (60s)
       └──────┬──────┘
              ▼
       ┌─────────────┐
       │ Docker Build│  ← Sequential (40s)
       └─────────────┘
```

### Job Breakdown

| Job | Time | Purpose | Dependencies |
|-----|------|---------|--------------|
| `format` | ~10s | Check code formatting | None |
| `clippy` | ~30s | Run linter | None |
| `build` | ~60s | Build release binary | format, clippy |
| `docker-build` | ~40s | Build Docker image | build |
| `summary` | ~5s | Report status | All jobs |

## Technical Achievements

### 1. Docker Buildx Integration

**Challenge**: Previous attempts failed with socket mounting

**Solution**: TCP-based DinD service
```yaml
services:
  docker:
    image: docker:dind
    command: ["dockerd", "--host=tcp://0.0.0.0:2375", "--tls=false"]
    options: >-
      --privileged
      -e DOCKER_TLS_CERTDIR=
```

**Benefits**:
- ✅ Isolated Docker daemon
- ✅ No permission issues
- ✅ Better security
- ✅ Works with Forgejo runner on Solaria

### 2. BuildKit Caching

```yaml
docker buildx build \
  --cache-from type=local,src=/tmp/.buildx-cache \
  --cache-to type=local,dest=/tmp/.buildx-cache-new,mode=max
```

**Benefits**:
- Faster subsequent builds (cache hits)
- Automatic cache rotation (prevents bloat)
- No external dependencies

### 3. Format Enforcement

```yaml
format:
  name: Check Code Formatting
  steps:
    - name: Check formatting
      run: cargo fmt --all -- --check
```

**Benefits**:
- Consistent code style across team
- Fails before build (faster feedback)
- Auto-fixable: `cargo fmt --all`

### 4. PR Validation

```yaml
on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main, develop]
```

**Benefits**:
- Automated PR checks
- Blocks merge if checks fail
- Supports both main and develop workflows

feat(ci): add format check, PR validation, and Docker buildx

- Add cargo fmt --check to enforce code formatting
- Add pull_request trigger for PR validation
- Split workflow into parallel jobs (format, clippy, build, docker)
- Integrate Docker Buildx with DinD service
- Add BuildKit caching for faster builds
- Add local test script (scripts/test-ci-locally.sh)
- Add comprehensive documentation

All local CI checks pass ✅
```

---

## Usage Guide

### For Developers

**Before Pushing**:
```bash
# Run local validation
./scripts/test-ci-locally.sh

# Fix any issues
cd backend
cargo fmt --all  # If format fails
cargo clippy --all-targets --all-features -- -D warnings  # If clippy fails
```

**After Pushing**:
- Monitor CI at: http://gitea.soliverez.com.ar/alvaro/normogen/actions
- All 4 jobs must pass
- Format and Clippy run in parallel (fast feedback)
- Docker image builds automatically

### For Pull Requests

1. Create PR to `main` or `develop`
2. CI automatically validates:
   - ✅ Code formatting
   - ✅ No Clippy warnings
   - ✅ Builds successfully
   - ✅ Docker image builds
3. Merge only after all checks pass

---

## Monitoring

### CI Dashboard

**URL**: http://gitea.soliverez.com.ar/alvaro/normogen/actions

**What to Watch**:
- Format check should complete in ~10s
- Clippy should complete in ~30s
- Build should complete in ~60s
- Docker build should complete in ~40s
- Total time: ~2.5 minutes

### Troubleshooting

**If format fails**:
```bash
cd backend && cargo fmt --all && git commit -am "style: fix formatting"
```

**If clippy fails**:
```bash
cd backend && cargo clippy --all-targets --all-features -- -D warnings
# Fix issues, then commit
```

**If Docker fails**:
- Check DinD service logs
- Verify TCP endpoint accessible
- Check runner configuration on Solaria
