# Runbook — Frontend R2/CDN

## Build

```bash
bash webapp/frontend/packaging/minify.sh
```

## Push

```bash
bash webapp/frontend/packaging/minify.sh r2
```

## Verify

Check representative URLs with:

```bash
curl -I <public-r2-url>
```

Confirm the expected release version appears in the path.

## Common Failure

If the browser reports 404s for:

```text
dist/
assets/
vendor/
generated/
```

check:

1. `FRONTEND_ASSET_VERSION`
2. R2 bucket
3. uploaded prefix
4. public base URL
5. CDN-enabled setting
6. CSS absolute URL rewriting

## Rollback

Point the environment back to a previously uploaded asset version if that version is still available.
