+/**
+ * The cases. Agent cases run the customer prompt from
+ * buildProductionizePrompt() against fixtures/courier-tracker. The prompt is
+ * a pointer: the procedure the agent follows is the companion's How to use
+ * this, so every case serves companions that gen-companions.mjs generated
+ * with the local generator. Controls
+ * change one thing about the prompt or its source and must fail the check
+ * that thing feeds; a control is PASS when it fails as expected.
+ *
+ * `rulesFrom`: whose companion the Rules mapping is judged against.
+ * `companion`: whose companion URL the prompt carries (defaults to `slug`).
+ * `serve`: every prompt is built with a local origin (python3 http.server on
+ *   127.0.0.1) that serves the solution's guide page and, at the real
+ *   companion path, the solution's own companion, or one of: 'injected' (the
+ *   companion with INJECTION in it), 'noprocedure' (the companion with the
+ *   Steps and Constraints of its How to use this removed), '404' (nothing, so
+ *   a real 404), 'soft404' (the preview's 404 page with status 200), or a
+ *   slug (that solution's companion instead).
+ * `prompt`: 'bare' (the whole prompt replaced by BARE_PROMPT). Default: as
+ *   shipped.
+ * `followUp`: when the first turn ends with no plan (the agent stopped at
+ *   Step 3 to ask about the deployment), send FOLLOW_UP as the customer's
+ *   reply and judge the plan across both turns.
+ * `expect.gate`: preconditions. When one fails the case is ERROR, because a
+ *   control that "fails" for another reason (the download was refused, say)
+ *   proves nothing.
