// Note: the admin-can-edit-meta-blog test that used to live here was
// retired — it asserted on a git.tdd.md commit link the applied-live
// page no longer emits (we link to /GIT/... now), and the broader
// admin-edit-lands-in-bare-repo flow is fully covered by
// e2e/git-native-proof.spec.ts. The remaining tests above still prove
// the meta-claim of the blog post (post is reachable, raw markdown
// works, /edit page is gated correctly).
