+"""Shadow evaluation (spec Part 6 step 3) — the reviewer records what it WOULD have decided
+on every approval card, while the human still decides everything. The invariant under test:
+shadow NEVER touches a decision, and the card is never delayed.

+Also covers the offline eval harness scoring logic (scripts/eval_reviewer.py) with the stub
+provider, so the ship-gate maths stays covered without a live model.
