# EditTaskInput

input type

Edit-input for a Task. Every field optional, at least ONE required; supplied fields REPLACE, omitted fields are preserved (no clearing semantic; the updateCsCase law). The id-set fields REPLACE their sets. ⚠ createdBy/linkedFromTaskId are NOT here — IMMUTABLE at birth; status moves ONLY via transitionTask; a terminal task refuses every edit (CONFLICT/IMMUTABLE).
