Here’s a quick, practical path to make your scanner’s findings show up in GitHub’s **Code scanning** UI with almost no integration work: emit **SARIF 2.1.0** and upload it.

---

### What SARIF is (and what GitHub expects)

* **SARIF** = Static Analysis Results Interchange Format, a JSON standard for static-analysis results. GitHub Code Scanning accepts a **subset** of **SARIF 2.1.0** and turns it into alerts in the Security tab. ([GitHub Docs][1])

---

### Three upload options (pick one)

1. **GitHub Actions**: add a step that uploads your SARIF file(s).

```yaml
# .github/workflows/upload-sarif.yml
name: Upload SARIF
on:
  push:
  schedule: [{cron: "0 3 * * 1"}]  # optional weekly recrawl
jobs:
  sarif:
    runs-on: ubuntu-latest
    permissions:
      security-events: write   # required to publish code scanning alerts
      contents: read
    steps:
      - uses: actions/checkout@v4
      - name: Run your scanner
        run: ./your_scanner --format sarif --out results.sarif
      - name: Upload SARIF to Code Scanning
        uses: github/codeql-action/upload-sarif@v3
        with:
          sarif_file: results.sarif
          category: your-scanner
```

This uses GitHub’s official **upload-sarif** action and is the easiest route. ([GitHub Docs][2])

2. **REST API**: gzip + base64 your SARIF and POST to `code-scanning/sarifs` (needs `security_events` scope for private repos). Useful if you run scans outside Actions. ([GitHub Docs][3])

3. **CodeQL CLI**: `codeql github upload-results --sarif-file results.sarif` (also needs proper token). Handy if you’re already using the CLI in your CI. ([GitHub Docs][4])

---

### Minimal SARIF you should emit

At minimum, include:

* `version: "2.1.0"`
* one `run` with your `tool.driver` (name, version)
* `results[]` with each finding’s `ruleId`, `message.text`, and at least one `location` (file/region) so GitHub can anchor it to code. (Empty or missing locations often breaks uploads.) ([GitHub Docs][1])

Skeleton:

```json
{
  "version": "2.1.0",
  "$schema": "https://json.schemastore.org/sarif-2.1.0.json",
  "runs": [{
    "tool": { "driver": { "name": "StellaOps Scanner", "version": "1.0.0" } },
    "results": [{
      "ruleId": "STELLA001",
      "message": { "text": "Vulnerability XYZ in package foo@1.2.3" },
      "locations": [{
        "physicalLocation": {
          "artifactLocation": { "uri": "src/app/foo.js" },
          "region": { "startLine": 42 }
        }
      }]
    }]
  }]
}
```

(Full schema: OASIS SARIF 2.1.0.) ([OASIS Open][5])

### Gotchas (save yourself time)

* **One tool/category per run**: GitHub is deprecating combining multiple runs with the same tool+category in a single upload; by **June 2025** such uploads will fail. Keep runs distinct or separate files. ([The GitHub Blog][6])
* **Partial fingerprints**: If you don’t provide them, the upload action can compute them (prevents duplicate alerts) when source is present. ([GitHub Docs][2])
* **Permissions**: in Actions, grant `security-events: write`. For API/CLI, use tokens with the right scopes. ([GitHub Docs][3])
* **PRs from forks**: public API uploads have restrictions; the `upload-sarif` action is the usual workaround in PR contexts. ([GitHub][7])

---

### Why this helps your rollout

* **Zero custom UI**: GitHub draws findings, file annotations, and PR decorations for you. ([GitHub Docs][1])
* **Fits any CI**: Emit SARIF once, then upload via Actions, REST, or CLI—works for GitHub-hosted or external runners. ([GitHub Docs][2])

If you want, I can tailor a ready-to-drop workflow for one of your Stella Ops repos (mono-repo vs multi-repo, language mix, and desired categories).
