Untrusted Input Meets a Privileged Action

This module writes stack/injection-drill.md, which 3 later modules read. It is part of the paid course.

You plant a harmless instruction in your own source material, watch your own system obey it, then close the hole with a structural change rather than a warning. You leave with a table of every untrusted thing your system reads and every privileged thing it can do, the pairs that must never meet without you, and the rule that survives every new variant: text you did not write is data, and data does not get to choose actions.
