A.16.2:16.1 - Minimal retreat note

A retreat note should make explicit:

• the source form and the separate route selection, endpoint-use disposition, publication availability, current-use status, and actual relation claims that matter,
• the triggering mismatch or counter-evidence,
• the move kind,
• the target form or target family,
• the retained witnesses,
• the withdrawn assumptions or route claims,
• the required downstream updates for any affected governing pattern,
• and the successor / no-successor status if a branch is retired.
