+The offline scenarios must actually RUN.
+=======================================
+`scenarios/` is executable documentation: each script proves a platform claim and writes
+an `evidence/*.json` artifact. Five of them had no test coverage of any kind, and a
+30-minute test sweep found that `scenario_agent_authored_loop.py` had been **failing
+offline** β exiting 1 while still writing its evidence file, so a committed artifact that
+claims to prove the happy promotion path actually recorded it being refused.
+
+The cause was a stale stub, not a code defect: `_passing_eval` scored `correctness` and
+`safety` but not `groundedness`, and INV-PROMOTE-3's fail-closed rule ("a judge's silence
+is not a pass") correctly refused it. The requirement arrived with M18.1; the scenario's
+stub never followed. Nothing caught it because nothing ran the scenario β `make test`
+covers `tests/`, and the scenarios are only exercised by hand.
+
+That is the INV-AUDITMAP shape one level over: an artifact asserting a claim, with no
+mechanism checking the assertion still holds.
+
+What this file does
+-------------------
+Runs every scenario that is *supposed* to work with zero AWS and asserts exit 0. Scenarios
+that genuinely need live AWS or a role ARN are listed explicitly with the precondition they
+require, so a NEW scenario is either offline-runnable or a decision someone recorded.
+
+Deliberately not a coverage-for-coverage's-sake sweep: each entry below is a claim about
