+# Headlamp Polaris Plugin - Project Assessment
+
+**Date:** 2026-02-11
+**Version:** v0.3.0
+**Status:** Active Development
+
+## Executive Summary
+
+This assessment identifies critical issues and improvement opportunities for the headlamp-polaris-plugin project. The plugin is currently non-functional in production due to Headlamp v0.39.0 compatibility issues, and has several TypeScript compilation errors that need immediate attention.
+
+---
+
+## 🔴 Critical Issues (Must Fix Immediately)
+
+### 1. TypeScript Compilation Errors
+**Severity:** CRITICAL
+**Impact:** Build failures, type safety compromised
+
+**Issues:**
+- `src/index.tsx:72` - `registerDetailsViewSection` expects 1 argument, got 2
+- `src/index.tsx:87` - `registerAppBarAction` expects 1 argument, got 2
+
+**Recommendation:**
+Update Headlamp plugin API calls to match the current version. Check @kinvolk/headlamp-plugin version compatibility.
+
+**Action Items:**
+- [ ] Review Headlamp plugin API documentation
+- [ ] Update `registerDetailsViewSection` and `registerAppBarAction` calls
+- [ ] Run `npm run tsc` to verify fixes
+- [ ] Update CI to fail on TypeScript errors
+
+---
+
+### 2. Production Plugin Loading Failure
+**Severity:** CRITICAL
+**Impact:** Plugin is completely non-functional in production
+
+**Root Cause:**
+Headlamp v0.39.0 with default `watchPlugins: true` treats catalog-managed plugins as "development directory" plugins, preventing frontend JavaScript execution.
+
+**Current Status:**
+- Deployment patched to install plugins to `/headlamp/static-plugins`
+- `watchPlugins: false` configured
+- Waiting for user to test if plugins now load
+
+**Action Items:**
+- [ ] Confirm plugins load after recent deployment changes
+- [ ] Document the fix in deployment guide
+- [ ] Update MEMORY.md with final resolution
+- [ ] Consider downgrading Headlamp if issue persists
+
+---
+
+### 3. Test Failures
+**Severity:** HIGH
+**Impact:** CI failures, reduced confidence in changes
+
+**Current Status:**
+- 1 test file failing (DashboardView)
+- 49 tests passing
+- Error related to `SimpleTable` component mock
+
+**Action Items:**
+- [ ] Fix DashboardView test mocking
+- [ ] Ensure all tests pass before merging PRs
+- [ ] Add test for top issues feature
+- [ ] Increase test coverage to >80%
+
+---
+
+## 🟡 High Priority Improvements

+
+**Action Items:**
+- [ ] Audit codebase for `any` types
+- [ ] Enable `noImplicitAny` and `strictNullChecks`
+- [ ] Add type guards for API responses
+- [ ] Document complex type structures
+
+---
+
+### 5. Security Hardening
+**Severity:** HIGH
+**Impact:** Prevent vulnerabilities, protect user data
+
+**Current Risks:**
+- Direct Kubernetes API access via service proxy
+- User input in exemption annotations (potential injection)
+- External URL configuration for Polaris dashboard
+
+**Recommendations:**
+- Validate and sanitize all user inputs
+- Implement input validation for dashboard URL
+- Add CSRF protection for exemption management
+- Audit dependencies for known vulnerabilities
+
+**Action Items:**
+- [ ] Add input validation utilities
+- [ ] Sanitize exemption annotation values
+- [ ] Validate URL format for dashboard configuration
+- [ ] Run `npm audit` and fix vulnerabilities
+- [ ] Add security testing to CI/CD
+
+---
+
+### 6. Error Handling & User Experience
+**Severity:** MEDIUM
+**Impact:** Better error messages, improved debugging
+
+**Current Gaps:**

+# Headlamp Plugin Loading Issue - Root Cause and Fix
+
+## Problem
+Headlamp v0.39.0 was not loading plugins installed via the plugin manager. Plugins appeared in Settings → Plugins but:
+- No sidebar entries appeared
+- No plugin settings were available
+- Plugin JavaScript was not being executed in the browser
+
+## Root Cause
+When `config.watchPlugins: true` (the default), Headlamp treats catalog-managed plugins in `/headlamp/plugins/` as "development directory" plugins. This causes:
+- Backend serves plugin metadata correctly
+- Backend logs show "Treating catalog-installed plugin in development directory as user plugin"
+- **Frontend does NOT execute the plugin JavaScript**
+- Plugin registrations (`registerSidebarEntry`, `registerRoute`, etc.) never happen
+
+## Solution
+Set `config.watchPlugins: false` in the Headlamp HelmRelease values:
+
+```yaml
+spec:
+  values:
+    config:
+      watchPlugins: false
+    pluginsManager:
+      enabled: true
+      configContent: |
+        plugins:
+          - name: polaris
+            source: https://artifacthub.io/packages/headlamp/polaris/headlamp-polaris-plugin
+          # ... other plugins
+```
+
+## Why This Works
+With `watchPlugins: false`:
+- Headlamp no longer treats catalog-managed plugins as "development" plugins
+- Frontend properly loads and executes plugin JavaScript on startup
+- Plugin registrations happen correctly
+- All plugin features (sidebar, routes, settings, etc.) work as expected
+
+## Testing
+After applying this fix:
+1. Verify plugins are installed: `kubectl logs -n kube-system <headlamp-pod> -c headlamp-plugin`
+2. Verify watchPlugins is false: `kubectl logs -n kube-system <headlamp-pod> -c headlamp | grep "Watch Plugins"`
+3. Hard refresh browser (Cmd+Shift+R / Ctrl+Shift+F5) to clear cached JavaScript
+4. Verify plugin sidebar entries appear
+5. Verify plugin functionality works
+
+## Additional Notes
+- This appears to be a bug/limitation in Headlamp v0.39.0
+- The `watchPlugins` feature is intended for development scenarios where plugins are being actively modified
+- For production deployments with catalog-managed plugins, `watchPlugins: false` is the correct configuration
+- Once plugins are loaded, subsequent restarts or updates work correctly as long as `watchPlugins` remains false
