 Injected fault: dropping `self.view_state = snapshot.view_state` from
 `App::restore` fails this test and only this test.
 
+**Addendum (improvise-gho5).** Improvise-gho5 found that this
+test and `a_rolled_back_load_tells_nobody_and_puts_every_mirror_back` passed
+against a host that **never ran the load**. The review's fault, reproduced
+here, was placed at the top of `Host::commands`: refuse any multi-command frame
+that contains a `LoadModel` with `Rejected(DocumentReplaced)`, before
+`CheckedBatch` runs. Both tests stayed green. A frame that never got that far
+leaves the generation, the view, the status line and every mirror untouched,
+which is exactly what the tests asserted.
+
+Both tests now assert that the asker's whole reply is
+`the_load_ran_then_the_write_broke()`, which is `Rejected(ChainBroken(North))`.
+They also assert, before the frame, that `North` resolves. Together these make
+the rejection a witness that the load ran. `ChainBroken` comes only from
+`reduce::broken_chain`, which runs inside `mutating_frame` just before each
+mutation. It names `North` only once the document no longer holds that
+record, and only an applied `LoadModel` in this frame can have removed it.
+
+With the same fault re-injected, both tests fail. The left side is
+`[Rejected(DocumentReplaced)]` and the right is
+`[Rejected(ChainBroken(<North>))]`. The fault was reverted.
+
+The residual: a rogue up-front check that forged `ChainBroken` specifically
+would still pass. That is the same forgery a hand-rolled client could commit
+against any basis check, and a test cannot guard against it.

+- **The load is witnessed to have RUN before anything is concluded from the
