He injected a single inline assembly block into the GetWaterFlow function:

That one-cycle delay was the only thing keeping the pressure valves from exploding.

The project loaded. Forty-three thousand lines of code, commented in a mix of German and English, with Hungarian notation that had died before Jenna was born. Aris navigated not by searching, but by instinct. He remembered writing parts of this in 2009. He remembered the exact bug fix in Update 2 (a memory leak in TClientDataSet ), the performance boost in Update 3 (faster TList iteration), and the crucial, undocumented change in Update 4: a hidden $IFDEF that allowed the compiler to read a proprietary checksum from a specific model of Siemens industrial PLC.

“It’s just old software,” Jenna said, panicking. “We’ll virtualize a Linux container and—” Aris navigated not by searching, but by instinct
