+# Project Hints and Findings
+
+## Properties Panel Element Detection Issue (Fixed)
+
+### Problem
+The properties panel had timing issues detecting rendered elements because:
+1. Elements are rendered asynchronously via lit's `render()` function in the dashboard component
+2. The properties panel tried to find elements immediately without waiting for render completion
+3. Element search only looked at direct children of the viewport, missing nested elements or those inside shadow DOM
+
+### Solution Implemented
+1. Added a 100ms initial delay to allow render completion
+2. Implemented recursive element search that:
+   - Searches through nested children up to 5 levels deep
+   - Checks shadow roots of elements
+   - Handles complex DOM structures
+3. Added retry mechanism with up to 5 attempts (200ms between retries)
+4. Improved error messages to show retry count
+
+### Code Flow
+1. Dashboard renders element demo into viewport using `render(anonItem.demo(), viewport)`
+2. Properties panel waits, then searches recursively for the element instance
+3. If not found, retries with delays to handle async rendering
+4. Once found, extracts and displays element properties

+# Fix Properties Panel Element Detection
+
+To fix the element detection issue, reread CLAUDE.md first.
+
+## Problem Analysis
+The properties panel has timing issues detecting rendered elements because:
+1. Elements are rendered asynchronously via lit's `render()` in the dashboard
+2. Properties panel tries to find elements immediately without waiting for render completion
+3. Element search only looks at direct children, missing nested/shadow DOM elements
+
+## Implementation Plan
+
+### 1. Add proper synchronization
+- Add a delay or await render completion before element detection
+- Use MutationObserver or lit's updateComplete promises
+
+### 2. Improve element search algorithm
+- Search recursively through all descendants, not just direct children
+- Handle shadow DOM boundaries properly
+- Support elements wrapped in containers
+
+### 3. Add retry mechanism
+- If element not found, retry after a delay
+- Add maximum retry attempts to prevent infinite loops
+- Clear error state when element is eventually found
+
+## Code Changes Required
+1. Modify `wcc-properties.ts` createProperties() method
+2. Add element search utility function
+3. Improve error handling and user feedback
