• Ticket-01KYND4SNNCPZ7R2NWFD7QXYTJ Add an external-key ownership map to the fold — One shared helper that answers "which items claim this remote ticket", so the link command and the sync dispatcher enforce the same rule from the same place instead of each growing its own copy. (done)
• Ticket-01KYND4SNP68XAJ30Q4PY4VV11 Stop sync from pushing a ticket that two items claim — Skip every item in a contested set, print a prominent block naming all claimants and the exact repair, and exit non-zero so the failure cannot be missed. (done)
• Ticket-01KYND4SNPBAW2A1H0GPHDGT0E Update the mirrored copies, the docs and the changelog — The command scripts ship in two places that must stay byte-identical. (done)
• Ticket-01KYND4SNPF2DYKSMDG4NJ39CF Refuse a duplicate external key when linking — Linking an item to a ticket another item already owns is the mistake that causes the corruption. (done)
• Ticket-01KYND4SNPG1HFE8E0P7F7K7PF Keep sync's automatic linking from ever aborting a run — Sync records the ticket key right after creating the ticket. (done)
• Ticket-01KYND4SNPH307DFDEE9BJ0ZZ4 Make undoing or moving a link actually re-push — The change detection only looks at an item's content, so unlinking or re-pointing it is silently a no-op and the damaged ticket is never repaired. (done)
• Ticket-01KYND4SNPXVR1W4GQA453VB4G Add a command to undo a link — A mistaken link is currently impossible to undo through supported commands, which is a sharp edge in a log designed so that mistakes are corrected by appending. (done)

Progress: 7/7 done
