+- **Steps 3–4 staging verified good**, including **SxS staging from BOTH patched delta AND

 **NEXT: step 5** — staged/unstaged split + post-stage reveal (stage from Normal / unstage
 from NormalSecondary, `<tab>`, synchronous next-hunk decision + restore-by-identity reveal).
 **Milestone: the working-tree staging panel is functionally replaced.** This is where the
-deferred post-stage selection re-anchor (§21.11) finally lands. Still pending:
-interactive sign-off of steps 3–4 (incl. SxS), and the unstage-from-secondary path.
