+"""Setup helpers for the sdd-go-fractals and sdd-svelte-todo drill scenarios.
+
+Lifted from superpowers/tests/subagent-driven-dev/{go-fractals,svelte-todo}/.
+The bash test family scaffolded a tiny project with only design.md +
+plan.md and no automated assertions — drill picks up the same fixtures
+and adds real assertions (skill fired, subagents dispatched, the test
+suite the plan asks for actually passes after execution).
+
+Both helpers initialize a fresh git repo, drop the design.md and plan.md
+fixtures from drill/fixtures/sdd-*, and commit. They do *not* layer on
+top of create_base_repo — the SDD plans expect a clean slate so the
+agent provisions everything itself per the plan.
