+- Lifts the obra/drill repo into superpowers as `evals/`, with explicit rsync excludes (.git, .venv, results, .env, __pycache__, *.egg-info, .private-journal). The lift commit records the source SHA.
 - Adds a `_set_superpowers_root_default()` helper to drill/cli.py so SUPERPOWERS_ROOT defaults to the parent of evals/ — no manual env-var setup.
 - Drops SUPERPOWERS_ROOT from required_env in codex.yaml/gemini.yaml (the helper supplies it). Claude*.yaml keep it because they interpolate ${SUPERPOWERS_ROOT} into --plugin-dir args.
 - Deletes redundant bash tests under tests/skill-triggering/, tests/explicit-skill-requests/, tests/subagent-driven-dev/, and tests/claude-code/ — gated per-file by a subagent that compared each bash test's assertions to its drill scenario's verify block. Anything not 100% covered was kept.
