    "explanation": "a runtime decode primitive (`gzuncompress`/`gzinflate`/`gzdecode`/`base64_decode`) feeds a filesystem write (`fwrite`/`file_put_contents`) which is then `include`d/`require`d as a variable path \u2014 the textbook dropper shape: ship an encoded payload as data, decode it to disk at activation/admin-init, and execute it. The siteguarding burner `wp-plugin-management` (audit #43) used exactly this: `fwrite($fp, gzuncompress($c)); include($filename);` in its `register_activation_hook` to plant `siteguarding_tools.php`. Near-zero FP because legit caching writes decoded data but never `include`s a computed path it just wrote."
