Description: "When a signed note is edited, the save action changes to 'Addend' and the status flips from Signed to Addended, but the note body remains freely editable in place with no visible indication of what text changed. This is a documentation/medicolegal auditability concern — practices need confidence that signed notes cannot be revised without a clear, visible record. Requested: either (a) lock signed notes from further inline editing (changes must go through a distinct addendum entry), or (b) a visible in-note log/audit trail showing exactly what was changed, by whom, and when — not just a status badge.
