I like the Employees Wash Hands sign. Recent batches of API tools seem focused on sanitizing IO: WebMCP, AI strings, safe native input parse, even Assembly mapping. So in a hot loop (whatever F35 anonymous lambda) you may have data change under you. So on antiquated hardware (like a Voyager I) maybe you want to flash the firmware to 3.5 after 70 years... but Iran has a HELLIOPARSER. It's imperative to be defensive transmitting data streams across the light years.
