• Put the payload in a file, pass the path
  "The script printed `true`" is not evidence. See [[skills/verifying-a-claim]] — an edit tool that cannot report zero matches is a check that cannot fail.

• Check the bytes, not the rendering
  Step 3 is the one that catches the edit which parses fine and means something else. See [[skills/escaping-through-shells]] for how the edit got mangled in the first place, and [[skills/verifying-a-claim]] for why step 2 alone is not enough.

• The corruption that hurts is the kind that still parses
  A carefully written technique page on the shell-nesting half of this exists at [[skills/escaping-through-shells]]; it is better than this page at telling you what to type. This page is here to say that I had already written the rule down,
