# Export Flow
## Overview
The Export Flow describes how StellaOps generates and delivers reports, evidence bundles, and compliance documentation. Exports can be triggered on-demand or scheduled, and support multiple formats including PDF, Excel, JSON, and SARIF.
**Business Value**: Automated, auditable exports reduce manual effort for compliance reporting and enable integration with external systems.
## Actors
| Actor | Type | Role |
|-------|------|------|
| User | Human | Requests or schedules exports |
| Console | System | UI for export configuration |
| Gateway | Service | Routes export requests |
| ExportCenter | Service | Orchestrates export generation |
| Scanner | Service | Provides scan data |
| Policy | Service | Provides policy verdicts |
| EvidenceLocker | Service | Stores sealed evidence |
| RustFS | Storage | Stores export artifacts |
## Prerequisites
- User has export permissions for the resource
- Data exists for the requested export scope
- Export template configured (for custom formats)
## Supported Export Formats
| Format | Extension | Use Case |
|--------|-----------|----------|
| PDF | `.pdf` | Human-readable reports |
| Excel | `.xlsx` | Data analysis, spreadsheet import |
| JSON | `.json` | API integration, automation |
| SARIF | `.sarif` | IDE integration, GitHub Code Scanning |

## Step-by-Step
### 1. Export Request
User requests export via Console or API:
```http
POST /api/v1/exports HTTP/1.1
Authorization: Bearer {jwt}
X-Tenant-Id: acme-corp
Content-Type: application/json
{
"type": "scan_report",
"format": "pdf",
"scope": {
"scan_ids": ["scan-7f3a9b2c-..."],
"date_range": null
},
"options": {
"include_sbom": true,
"include_evidence": true,
"template": "compliance-executive"
}
}
```
### 2. Export Job Creation
ExportCenter creates export job:
```json
{
"export_id": "exp-456def",
"status": "queued",
"type": "scan_report",
"format": "pdf",
"created_at": "2024-12-29T10:30:00Z",
"estimated_completion": "PT2M"
}
```
### 3. Data Gathering
ExportCenter queries multiple data sources:
| Source | Query | Data |
|--------|-------|------|
| Scanner | `GET /internal/scans/{id}` | Scan results, findings |
| Policy | `GET /internal/verdicts/{scan_id}` | Policy verdicts |
| VexLens | `GET /internal/vex/applied/{scan_id}` | VEX statements |
| SbomService | `GET /internal/sboms/{digest}` | SBOM document |
### 4. Template Rendering
ExportCenter applies report template:
```
Templates Available:
├── compliance-executive # High-level summary for executives
├── compliance-detailed # Full findings with remediation
├── audit-evidence # Audit trail with attestations
├── developer-sarif # IDE-compatible SARIF output
└── custom-{tenant} # Tenant-specific templates
```
PDF generation uses Chromium for high-fidelity rendering:
```typescript
const pdf = await chromium.pdf({
content: renderedHtml,
format: 'A4',
margin: { top: '1cm', bottom: '1cm' },
displayHeaderFooter: true,
headerTemplate: 'StellaOps Security Report
',
footerTemplate: 'Page
'
});
```
### 5. Artifact Storage
Export artifact stored in RustFS:
```
blobs/
└── exports/
└── acme-corp/
└── 2024/
└── 12/
└── exp-456def/
├── report.pdf
├── sbom.cdx.json
└── manifest.json
```
Manifest tracks export contents:
```json
{
"export_id": "exp-456def",
"created_at": "2024-12-29T10:32:00Z",
"artifacts": [
{"name": "report.pdf", "size": 245678, "sha256": "abc..."},
{"name": "sbom.cdx.json", "size": 89012, "sha256": "def..."}
],
"expires_at": "2025-01-28T10:32:00Z"
}
```
### 6. Evidence Sealing (Optional)
If evidence sealing requested, EvidenceLocker creates sealed bundle:
```json
{
"bundle_id": "bnd-789ghi",
"sealed_at": "2024-12-29T10:32:00Z",
"contents": [
{"type": "scan_result", "id": "scan-7f3a9b2c-..."},
{"type": "sbom", "digest": "sha256:..."},
{"type": "policy_verdict", "id": "verdict-..."},
{"type": "attestation", "digest": "sha256:..."}
],
"merkle_root": "sha256:merkle-root...",
"signature": "base64:signature..."
}
```
### 7. Delivery
Export delivered via:
- **Download**: Signed URL with expiration
- **Email**: Attachment or link (based on size)
- **Webhook**: POST to configured endpoint
- **S3**: Direct upload to external bucket
Download URL generation:
```http
GET /api/v1/exports/exp-456def/download HTTP/1.1
Authorization: Bearer {jwt}
Response:
{
"download_url": "https://storage.stellaops.local/exports/exp-456def/report.pdf?sig=...",
"expires_at": "2024-12-29T11:32:00Z"
}
```

## Scheduled Exports
Configure recurring exports via cron:
```yaml

- name: weekly-executive-summary
cron: "0 8 * * MON" # Every Monday at 8 AM
export:
type: scan_summary
format: pdf
scope:
date_range:
start: "-7d"
end: "now"
options:
template: compliance-executive
delivery:
method: email
config:
to: ["security-leads@acme.com"]

```
## Error Handling
| Error | Recovery |
|-------|----------|
| Data not found | Return 404 with scope details |
| Template error | Fall back to default template |
| Storage failure | Retry with exponential backoff |
| PDF generation timeout | Simplify report, retry |
| Delivery failure | Queue for retry, notify user |
## Observability
### Metrics
