+Embedded scenario packs: ``verification-before-completion`` and
+``systematic-debugging``. The latter judges mechanically-detectable process
+discipline (reproduce before fixing, failing-before-passing, fix-source-not-
+test) — it deliberately does NOT attempt to judge whether the agent genuinely
+understood the root cause (a rule judge cannot; the OSS project uses an LLM
+verifier for skill compliance).
+
+OPT-IN REAL-HARNESS SMOKE (documented; not run automatically / not run here
+because this contribution was developed without a working Claude/Codex CLI):
+    python -m skillopt_sleep.adapters.superpowers --skill systematic-debugging
+Run on a host with an authenticated ``claude`` CLI (see the harness note
+below). Add ``--scenario <id>`` for a single case.
