Why should a correction be modelled as a controlled state transition?

Correcting a record is rarely just replacing an incorrect number. A business needs to establish what happened, decide which correction is justified, identify who may authorise it and preserve the connection between the original entry and the resulting change. The operational challenge sits between recognising an error and gaining permission to fix it.

For environment builders, that gap creates useful action space. An agent can gather evidence, propose an adjustment, request authority or stop because the available information does not support a change. Each action should affect what becomes possible next. A correct calculation alone should not unlock posting.

MirrorFirm could generate environments informed by direct observation of business workflows, with correction requests moving through explicit states such as drafted, submitted, authorised and posted. The commercial material would be generated records, tasks and environment state.

This supports training and evaluation of procedural judgement. The central question is whether an agent understands that identifying the desired final value and being entitled to write that value are separate achievements.
