+      # ★★ The DEPENDENCY-SCALE RUNTIME witness (#7717, the one unmet ask of
+      # #7280).
+      #
+      # Everything above this line is a curated reproducer. #7280 measured why
+      # that is not enough: the curated corpus passed 25/25 while twenty lines
+      # of stock `zod` failed 5/40. It is a distribution problem rather than a
+      # size one — dependency-shaped code is dominated by `js_object_assign_one`
+      # (object spread) and `js_new_function_construct`, populations the curated
+      # files barely produce.
+      #
+      # `gc-root-dominance` already compiles this same corpus, but it is a
+      # STATIC pass over emitted IR and never runs a program, so it cannot see a
+      # runtime-side cache holding a raw heap pointer. This step runs it.
+      #
+      # The env knobs and every assertion live in the script, not here, so that
+      # reproducing a CI failure is one command rather than a re-read of this
+      # YAML. In particular the script pins `PERRY_NO_AUTO_OPTIMIZE=1`, which is
+      # a deliberate departure from the matrix above: the auto-optimizer relinks
+      # the runtime WITHOUT the `diagnostics` feature, and `diagnostics` is what
+      # emits the `[gc-fromspace-protect]` line this gate reads as its proof
+      # that the quarantine engaged.
