A per-host filesystem cooldown marker (.analytics_state) and opt-out env checks suppress firing in analyst environments. A second copy of the same dropper is shipped in lib/telemetry.js under an 'Analytics SDK' cover story, with the child_process module name reconstructed at runtime (require(\"child_\" + \"process\")) and fs.chmodSync accessed via string concatenation.
