+## 🧪 End-to-End Validation
+Use the manual workflow `.github/workflows/manual-e2e-validate.yml` to validate this action against the centralized E2E repository.
+
+- `mode=ref` validates ref-oriented E2E paths against stable pinned action refs.
+- `mode=image` is wired but currently placeholder-only in the central E2E workflow for this action.
+
+CI/CD automation also runs these E2E checks automatically:
+
+- Pull requests: E2E validation runs through reusable org workflows.
+- Release branch prepare: E2E validation runs against release candidate refs.
+- Release create: E2E validation runs against production release refs.
+
+Example trigger inputs:
+
+```text
+mode=ref
+```
+
+```text
+mode=image
+image_tag=v1.2.3-test
+```
+
 ## Forking
 To publish images from a fork, set these variables so Task uses your registry identities:
 `DOCKER_USERNAME`, `DOCKER_ORG_NAME`, `GITHUB_USERNAME`, `GITHUB_ORG_NAME`.
