# One-shot implementation/optimization plans, migration-progress ledgers,
# design specs, and agent-generated working notes (e.g. anything a
# `superpowers`/scratch workflow produces) belong in the issue tracker or a
# local worktree, never in the repository — see AGENTS.md "Sources of Truth".
#
# .gitignore already keeps everything under docs/ out of the tree except the
# whitelisted durable subtrees (architecture/, operations/, testing/), but
# `git add -f` bypasses .gitignore. This guard closes that hole: any tracked
# file under docs/superpowers/ fails the check regardless of how it got added.
