  accTitle: ASILO: from proposal to effect
  accDescr: A proposal passes successive decisions: meeting the contract, the identity's permission for the action, human review when the catalogue requires it with approval of the exact object, valid scope with available budget, and permission still valid at the point of effect. Any negative answer leads to rejecting and recording the reason, except missing approval, which leaves the proposal waiting with its state preserved; if everything is met, only the authorised action is performed and its outcome recorded.
