Clerk was net-negative on the #963 push: non-exhaustive (three distinct real D-202 inconsistencies surfaced only on successive re-pushes, each run missing the others — so APPROVED can't be trusted) and it re-reviews the whole range every push (token burn, no verdict cache). Gate it behind SR_RUN_CLERK=1 (default off). Rework tracked in #965; decision-record consistency is the author's responsibility until then.
