 ## Final Checks
 
 - Re-read the updated `dedupe-issue-local` companion skill and confirm any new clusters are explicit.
 - Keep the companion concise; prefer canonical links and short distinguishing notes over long prose.
-- Commit any changes on a local branch named `oz-agent/update-dedupe`. Do NOT push the branch; the Python entrypoint will run a write-surface guard and push only when the guard passes.
