Ported from the setup in enterprise-data-services. On push, one headless claude -p session (read-only tools) runs three repo-local skills on origin/main...<pushed sha>:

• check-docs: docs the diff makes false, prose tells, comment density
• check-scope: changes that don't trace to the commit messages, speculative code
• check-tests: tests that can't fail, behavior changes with no test

A ⚠️ finding blocks the push. The suite skips itself when claude is missing, the diff is empty, the push only deletes, or there's no verdict. SKIP=check-suite git push bypasses it on purpose.

The hook is now tracked in .githooks/pre-push (ruff check, ruff format, pytest, then the suite). Enable it once per clone with git config core.hooksPath .githooks. There's no new dependency.

The last two commits are the linked-worktree test fixes also on #22.
