+   isolation usually clones *the session's* repo, which is not the target when
+   the cockpit is reviewing a different one (an adopter repo, a sibling
+   checkout). On the OpenKitchen upgrade both lenses were handed a worktree of
+   the *kit* while reviewing the *adopter*: `git diff <base>...HEAD` was empty in
+   both. Both noticed and cloned the real target themselves — but a lens that
+   did not would have reviewed an empty diff and reported all-clear, which is
+   the worst failure available to a review mechanism.
+
+   So: name the target repo explicitly in the launch prompt, tell the lens to
+   **verify it is looking at the right thing before reviewing** (a non-empty diff
+   with the expected head), and never state in the prompt that isolation has
+   already been arranged unless you have confirmed it. The launch prompt on that
+   run asserted "you are in an isolated worktree of that repo" and was wrong.
 8. **State what was verified clean, and how.** Absence of findings is only
    evidence if you know what was actually checked.
