-"""Skills operations must preserve ownership across same-slug skills.
+"""Independent validation test for the claim that
+`SkillsManager.update_skill` mutates the first skill on disk matching
+`name` regardless of the caller's owner, and that `owner` is in its
+`scalar_keys` whitelist allowing cross-user ownership reassignment.
 
-An unscoped update may match only ownerless skills. With Alice's and Bob's
-skills sharing a slug, it must return False and leave both files unchanged.
-Unexpected implementation errors must fail the regression test.
+This test sets up two user-owned skills on disk with the SAME slug
+(`login-flow`) — Alice's and Bob's — and then calls `update_skill` with
+NO `owner` argument. If the bug is real, exactly one of the two files
+will be mutated (whichever `_iter_skill_files` yields first) and the
+caller will have effectively re-stamped the file as owned by the value
+in `updates["owner"]` ("attacker"). If the manager method is safe (or
+the slug uniqueness invariant makes the bug moot), the call should
+either:
+  * raise (it requires an `owner` argument), OR
+  * be a no-op (no other side effect on Bob's file), OR
+  * the file that gets modified should still belong to its original
+    owner (no ownership reassignment).
+
+We assert the safer behaviors; the test FAILS only when update_skill
+silently mutates a file owned by a different user AND overwrites the
+`owner` field with an attacker's value.
