+When sync processes an implementation:
 
-1. **Fetch on-chain bytecode** from the implementation address
-2. **Compare three versions**: local artifact, on-chain, address book
-3. **Auto-heal** if local matches on-chain:
+1. **Compare local artifact hash to address-book-stored hash**
+2. **If hashes match**: sync the implementation record to rocketh normally
+3. **If hashes don't match**: overwrite any stale rocketh record with empty bytecode, forcing a fresh deployment
 
    ```typescript
-   if (localHash === onChainHash) {
-     // Update address book with verified hash
-     hashMatches = true
-     shouldSync = true
-     syncNotes.push('hash verified' or 'hash healed')
+   if (storedHash && localHash) {

+   }

+   // Clean up stale rocketh record if hash doesn't match
+   if (!hashMatches && existingImpl) {
+     // Overwrite stale record with empty bytecode - forces fresh deployment

-   - `impl state unclear` - all three hashes differ (investigation needed)

-- First sync after fix will fetch on-chain bytecode and update hashes
-- Address book will be updated in place with correct metadata
-- Subsequent syncs will use the healed hashes
