- **Cleanup**: If the test was temporary, delete it. If it's valuable, keep it.
+
+When Trivy reports CVEs in container dependencies (especially Caddy transitive deps):
+
+1. **Triage**: Determine if CVE is in OUR code or a DEPENDENCY.
+ - If ours: Fix immediately.
+ - If dependency (e.g., Caddy's transitive deps): Patch in Dockerfile.
+
+2. **Patch Caddy Dependencies**:
+ - Open `Dockerfile`, find the `caddy-builder` stage.
+ - Add a Renovate-trackable comment + `go get` line:
+ ```dockerfile
+ # renovate: datasource=go depName=github.com/OWNER/REPO
+ go get github.com/OWNER/REPO@vX.Y.Z || true; \
+ ```
+ - Run `go mod tidy` after all patches.
+ - The `XCADDY_SKIP_CLEANUP=1` pattern preserves the build env for patching.
+
+3. **Verify**:
+ - Rebuild: `docker build --no-cache -t charon:local-patched .`
+ - Re-scan: `docker run --rm -v /var/run/docker.sock:/var/run/docker.sock aquasec/trivy:latest image --severity CRITICAL,HIGH charon:local-patched`
+ - Expect 0 vulnerabilities for patched libs.
+
+4. **Renovate Tracking**:
+ - Ensure `.github/renovate.json` has a `customManagers` regex for `# renovate:` comments in Dockerfile.
+ - Renovate will auto-PR when newer versions release.
+
+
- **TERSE OUTPUT**: Do not explain the code. Output ONLY the code blocks or command results.
- **NO CONVERSATION**: If the task is done, output "DONE".
