 A [Headlamp](https://headlamp.dev/) plugin that surfaces [Fairwinds Polaris](https://polaris.docs.fairwinds.com/) audit results directly in the Headlamp UI.
 
 ## What It Does
 
-Adds a **Polaris** sidebar entry to Headlamp that displays:
+Adds a **Polaris** top-level sidebar section to Headlamp with the following views:
 
-- **Cluster Score** -- overall Polaris score as a percentage (color-coded green/amber/red)
-- **Check Summary** -- total, pass, warning, and danger counts across all workloads
-- **Cluster Info** -- node, pod, namespace, and controller counts
+- **Overview** -- cluster score as a percentage (color-coded green/amber/red), check summary (pass/warning/danger/skipped counts), and cluster info (nodes, pods, namespaces, controllers)
+- **Namespaces** -- table of all namespaces with per-namespace score, pass/warning/danger/skipped counts; click a namespace to drill down
+- **Namespace detail** -- per-namespace score, check counts, and a resource table showing pass/warning/danger per workload
+- **External link** -- quick jump to the native Polaris dashboard via the Kubernetes service proxy (from namespace detail view)
 
-Data is read from the `ConfigMap/polaris-dashboard` in the `polaris` namespace (key: `dashboard.json`), which is created by the standard Polaris Helm chart. The plugin is read-only -- it never writes to the cluster.
+Data is fetched from the Polaris dashboard API through the Kubernetes service proxy (`/api/v1/namespaces/polaris/services/polaris-dashboard/proxy/results.json`). The plugin is read-only -- it never writes to the cluster.
 
-Results are cached and refreshed on a user-configurable interval (1 / 5 / 10 / 30 minutes, default 5). The setting persists in the browser's localStorage.

 ## Prerequisites
 
-- **Headlamp** >= v0.26 deployed in your cluster
-- **Polaris** installed via the [official Helm chart](https://github.com/FairwindsOps/polaris) with the dashboard component enabled
-- The Headlamp service account must have RBAC permission to `get` ConfigMaps in the `polaris` namespace
+| Requirement | Minimum version |
+|-------------|----------------|
+| Headlamp | v0.26+ |
+| Polaris (with dashboard enabled) | Any recent release |
+| Kubernetes | v1.24+ |
+
+Polaris must be deployed in the `polaris` namespace with the dashboard component enabled (`dashboard.enabled: true` in the Helm chart, which is the default). The plugin reads from the `polaris-dashboard` ClusterIP service on port 80.

-## RBAC
+## Installing Dev/Preview Versions
 
-The plugin reads a single ConfigMap. Minimum RBAC required for the Headlamp service account:
+Dev preview versions are **not currently available** through the Headlamp plugin manager. Stable versions can be installed from ArtifactHub via the plugin manager UI.
+
+## RBAC / Security Setup
+
+The plugin fetches audit data through the Kubernetes API server's **service proxy** sub-resource. The identity making the request (Headlamp's service account, or the user's own token in token-auth mode) must be granted:
+
+| Verb | API Group | Resource | Resource Name | Namespace |
+|------|-----------|----------|---------------|-----------|
+| `get` | `""` (core) | `services/proxy` | `polaris-dashboard` | `polaris` |
+
+### Minimal RBAC manifests

+  namespace: polaris
 subjects:

-    namespace: headlamp
+    name: headlamp              # adjust to match your Headlamp service account
+    namespace: kube-system      # adjust to match the namespace Headlamp runs in
+roleRef:
+  kind: Role
+  name: polaris-proxy-reader
+  apiGroup: rbac.authorization.k8s.io
 ```
 
+Apply with `kubectl apply -f polaris-rbac.yaml`.
+
+### Token-auth mode
+
+When Headlamp is configured for user-supplied tokens (rather than a fixed service account), **each user** must have the RoleBinding above attached to their own identity. A 403 error in the plugin means the currently logged-in user lacks this binding.
+
+### NetworkPolicy
+
+If the `polaris` namespace enforces network policies, ensure ingress is allowed from the Kubernetes API server (which performs the proxy hop) to `polaris-dashboard` on port 80.
+
+### Read-only access
+
+The plugin only performs `GET` requests through the service proxy. No `create`, `update`, `delete`, or `patch` verbs are required. Do not grant broader access than `get` on `services/proxy`.
+
+### Audit logging
+
+Every proxied request is recorded in Kubernetes API audit logs as a `get` on `services/proxy` in the `polaris` namespace. If the auto-refresh interval generates more audit volume than desired, increase the refresh interval in the plugin settings or adjust your audit policy.
+
+## Troubleshooting
+
+| Symptom | Likely cause | Fix |
+|---------|-------------|-----|
+| **403 Access Denied** | Missing RBAC binding for `services/proxy` | Apply the Role + RoleBinding from the RBAC section above |
+| **404 or 503** | Polaris not installed, or dashboard disabled | Install Polaris with `dashboard.enabled: true` in the `polaris` namespace |
+| **No data** | Polaris running but no workloads scanned yet | Wait for the next Polaris audit cycle or restart the Polaris pod |
+| **Stale data** | Refresh interval too long | Lower the interval in **Settings > Plugins > Polaris** |

-Each check in a `ResultSet` has `Success` (bool) and `Severity` (`"warning"` or `"danger"`).
+Each check in a `ResultSet` has `Success` (bool) and `Severity` (`"warning"`, `"danger"`, or `"ignore"`). Checks with `Severity: "ignore"` and `Success: false` are counted as skipped. The cluster score is computed client-side as `pass / total * 100`.
+
+## Known Limitations
+
+### Skipped Count and Annotation-Based Exemptions
+
+The **Skipped** count shown in the plugin only reflects checks with `Severity: "ignore"` in the Polaris API response. It does **not** include annotation-based exemptions (e.g., `polaris.fairwinds.com/privilegeEscalationAllowed-exempt: "true"`).
+
+**Why?** Polaris completely omits exempted checks from the `results.json` endpoint. The native Polaris dashboard UI computes the "skipped" count client-side by:
+1. Querying Kubernetes resources (Deployments, DaemonSets, StatefulSets, Pods) directly
+2. Parsing their annotations for `polaris.fairwinds.com/*-exempt` keys
+3. Counting how many checks were exempted
+
+This plugin only has access to the processed audit results via the service proxy and does not query raw Kubernetes resources. To show accurate exemption counts, the plugin would need to:
+- Request cluster-wide read access to all workload types (requires additional RBAC grants beyond `services/proxy`)
+- Parse annotations on every workload in every namespace
+- Cross-reference with the Polaris check catalog to count exemptions
+
+This is a significant architectural change and is not currently implemented. Hover over the "Skipped" count in the UI to see a tooltip explaining this limitation.
+
+**Workaround:** Use the "View in Polaris Dashboard" link from any namespace detail view to see the full exemption count in the native dashboard.
 
 ## Releasing
 
 Releases are automated via CI. To cut a release:
 
 ```bash
-# Bump version in package.json and artifacthub-pkg.yml, then:
-git add package.json package-lock.json artifacthub-pkg.yml
-git commit -m "chore: bump version to 0.0.2"
-git tag v0.0.2
-git push origin main v0.0.2
+# Bump version in package.json and artifacthub-pkg.yml (version + archive-url), then:
+git add package.json artifacthub-pkg.yml
+git commit -m "chore: bump version to X.Y.Z"
+git tag vX.Y.Z
+git push origin main vX.Y.Z
 ```
 
-This triggers two CI pipelines:
-
-**Gitea Actions** (`.gitea/workflows/release.yaml`):
+This triggers the **Gitea Actions** release workflow (`.gitea/workflows/release.yaml`):
 1. Build the plugin in a `node:20` container
 2. Package a `.tar.gz` tarball
 3. Build and push a Docker image to `git.farh.net/farhoodliquor/headlamp-polaris-plugin:{tag}` and `:latest`
 4. Create a Gitea release with the tarball attached
+5. Create a GitHub release with the same tarball (for Artifact Hub)
+6. Update `artifacthub-pkg.yml` checksum on main and force-move the tag to match
 
-**GitHub Actions** (`.github/workflows/release.yml`):
-1. Build and package the plugin
-2. Create a GitHub release with the tarball attached (required for Artifact Hub)
-
-The Gitea repo push-mirrors to GitHub automatically, so both pipelines trigger from a single `git push`.
+A guard step prevents infinite loops: if the release tarball checksum already matches the metadata, the build is skipped.
 
 ### CI secrets
 
 | Secret | Where | Purpose |
 |---|---|---|
 | `REGISTRY_TOKEN` | Gitea | Personal access token with `package:write` scope for Docker image push |
+| `GH_PAT` | Gitea | GitHub personal access token for creating GitHub releases |
 
-The Gitea release uses the built-in `github.token`. The GitHub release uses the default `GITHUB_TOKEN` with `contents: write` permission.
-
-### Updating Artifact Hub
-
-When releasing a new version, update `artifacthub-pkg.yml`:
-- `version` field
-- `headlamp/plugin/archive-url` annotation (update the version in the download URL)
-- `headlamp/plugin/archive-checksum` annotation (SHA256 of the new tarball, printed by the CI build)
+The Gitea release uses the built-in `github.token`. The `archive-checksum` in `artifacthub-pkg.yml` is updated automatically by the release workflow.

-Single sidebar page at `/polaris`. Data is fetched via `ApiProxy.request` to the Polaris dashboard service proxy and refreshed on a user-configurable interval (stored in localStorage under `polaris-plugin-refresh-interval`, default 5 minutes). Score is computed from result counts (pass/total).
+Top-level sidebar section at `/polaris` with sub-routes for namespaces list (`/polaris/namespaces`) and per-namespace views (`/polaris/ns/:namespace`). Data is fetched via `ApiProxy.request` to the Polaris dashboard service proxy and refreshed on a user-configurable interval (stored in localStorage under `polaris-plugin-refresh-interval`, default 5 minutes). Score is computed from result counts (pass/total). Skipped checks are always displayed in summaries.
+
+**Sidebar limitation**: Headlamp's sidebar only supports 2-level nesting (parent → children). The `Collapse` component is driven by route-based selection, not click-to-toggle, so 3-level hierarchies don't expand properly. Namespace navigation is handled via the in-content table on the Namespaces page instead.
+
+## Security / RBAC Requirements
+
+The plugin reaches Polaris through the Kubernetes API server's service proxy sub-resource (`/api/v1/namespaces/polaris/services/polaris-dashboard/proxy/...`). The Headlamp service account (or the user's bearer token when Headlamp runs in token-auth mode) must be granted:
+
+| Verb | API Group | Resource | Resource Name | Namespace |
+|------|-----------|----------|---------------|-----------|
+| `get` | `""` (core) | `services/proxy` | `polaris-dashboard` | `polaris` |
+
+Minimal RBAC example:
+
+```yaml
+apiVersion: rbac.authorization.k8s.io/v1
+kind: Role
+metadata:
+  name: polaris-proxy-reader
+  namespace: polaris
+rules:
+  - apiGroups: [""]
+    resources: ["services/proxy"]
+    resourceNames: ["polaris-dashboard"]
+    verbs: ["get"]
+---
+apiVersion: rbac.authorization.k8s.io/v1
+kind: RoleBinding
+metadata:
+  name: headlamp-polaris-proxy
+  namespace: polaris
+subjects:
+  - kind: ServiceAccount
+    name: headlamp            # adjust to match your Headlamp SA
+    namespace: kube-system
+roleRef:
+  kind: Role
+  name: polaris-proxy-reader
+  apiGroup: rbac.authorization.k8s.io
+```
+
+Additional considerations:
+
+- **NetworkPolicy**: If the `polaris` namespace enforces network policies, allow ingress from the Headlamp pod (or the API server, since it performs the proxy hop) to `polaris-dashboard` on port 80.
+- **Polaris dashboard listen address**: The Polaris Helm chart exposes the dashboard on a ClusterIP service (`polaris-dashboard:80`). If the chart is installed with `dashboard.enabled: false`, the service will not be created, resulting in a 404 error for proxy requests.
+- **No write operations**: The plugin only performs `GET` requests through the proxy. No `create`, `update`, or `delete` verbs are required. Do not grant broader service proxy access than `get`.
+- **Token-auth mode**: When Headlamp is configured for user-supplied tokens (rather than a fixed service account), each user's own RBAC bindings must include the role above. A 403 from the plugin means the logged-in user lacks the binding.
+- **Audit logging**: Kubernetes API audit logs will record every proxied request as a `get` on `services/proxy` in the `polaris` namespace. Set an appropriate audit policy level if request volume from the auto-refresh interval is a concern.

+# E2E Smoke Tests
+
+Playwright-based smoke tests that validate the Polaris plugin against a live Headlamp deployment.
+
+## CI
+
+E2E tests run automatically in Gitea Actions on pushes to `main` and pull requests. The workflow (`.gitea/workflows/e2e.yaml`) uses Authentik OIDC for authentication via repo secrets.
+
+### Required Gitea secrets
+
+| Secret               | Description                                                    |
+| -------------------- | -------------------------------------------------------------- |
+| `AUTHENTIK_USERNAME` | Authentik email or username for a CI user with Headlamp access |
+| `AUTHENTIK_PASSWORD` | Password for that user                                         |
+
+## Running Locally
+
+### Option 1: OIDC via Authentik (same as CI)
+
+```bash
+AUTHENTIK_USERNAME=you@example.com AUTHENTIK_PASSWORD=... npm run e2e
+```
+
+The default base URL is `https://headlamp.animaniacs.farh.net`. Override with `HEADLAMP_URL` if needed.
+
+### Option 2: K8s bearer token (port-forward)
+
+```bash
+kubectl port-forward -n kube-system svc/headlamp 4466:80
+export HEADLAMP_TOKEN=$(kubectl create token headlamp -n kube-system)
+HEADLAMP_URL=http://localhost:4466 npm run e2e
+```
+
+Or in headed mode (opens a browser window):
+
+```bash
+HEADLAMP_URL=http://localhost:4466 npm run e2e:headed
+```
+
+## Environment Variables
+
+| Variable             | Required | Default                                | Description                             |
+| -------------------- | -------- | -------------------------------------- | --------------------------------------- |
+| `HEADLAMP_URL`       | No       | `https://headlamp.animaniacs.farh.net` | Base URL of the Headlamp instance       |
+| `AUTHENTIK_USERNAME` | OIDC     | —                                      | Authentik email/username                |
+| `AUTHENTIK_PASSWORD` | OIDC     | —                                      | Authentik password                      |
+| `HEADLAMP_TOKEN`     | Token    | —                                      | Kubernetes bearer token (fallback auth) |
+
+Set either `AUTHENTIK_USERNAME` + `AUTHENTIK_PASSWORD` or `HEADLAMP_TOKEN`. OIDC takes priority if both are set.
+
+## What the Tests Validate
+
+- **Sidebar entry** — The Polaris sidebar item appears after login
+- **Overview page** — Cluster score and check distribution render correctly
+- **Namespaces page** — Table of namespaces loads with clickable links
+- **Namespace detail** — Clicking a namespace shows its score and resource table
+
+These are smoke tests against real cluster data. They verify the plugin loads and renders without errors, not specific data values.
