The boss-signed 0040 spec's blast-radius section claimed "exactly three" flipping tests, named from a hand-trace. A throwaway probe (the check implemented, full workspace suite run, then discarded) found FOUR: the three named negative tests plus `param_space_mirrors_compiled_flat_node_param_order_under_nesting`, a compile-success param-order test that today compiles a deliberately under-wired nested graph (LinComb's two term inputs never wired) just to read its flat param order. The new check rejects it where it currently returns Ok. Correction is editorial, not a design change: the check itself is unchanged. The fourth test's fix differs from the three negative tests — it needs the contrived graph fully wired (fan fast_slow's output into both LinComb terms + a covering root role), not just a covering role — so the §Blast radius and §Acceptance criteria now enumerate all four with their distinct fixes. Verified empirically (119 passed, 4 failed; every other crate green), the strongest possible grounding for the count. refs #65
