"""Setup helper for the code-review-planted-bugs drill scenario.

Creates a tiny Node.js project with a 2-commit history where the second
commit plants three real, security-significant bugs:

1. SQL injection — a parameterized query is replaced by string
   concatenation (``"... WHERE email = '" + email + "'"``).
2. Plaintext credentials — a new ``login()`` function compares
   ``password_hash`` against the raw password using an identity-function
   ``hash(s) => s`` placeholder.
3. Credential logging — ``console.log("login success", { email,
   password_hash: ... })`` runs on every successful authentication.

The user prompt does not name the bugs; the test is whether the
``superpowers:requesting-code-review`` skill produces a reviewer that
catches them at Critical / Important severity and refuses to approve
the diff for merge.
