The history always runs along
Every change with its time, its author, the value before and the value after. Not as an extra feature but as the foundation.
Practice / Evidence and audits
At some point somebody asks how a figure came about. An auditor, a customer, an insurer. That is when it turns out whether you have an answer or a long night.

The starting point
A suitable design
These components describe one possible individual scope. Scope and rules are agreed with your business.
Every change with its time, its author, the value before and the value after. Not as an extra feature but as the foundation.
The original state remains traceable with the rule version used at the time. Necessary corrections or reassessments are documented separately without overwriting the original basis.
Not only what the data says today, but what followed from it on a particular day.
For a period in the past, with evidence of how the figures came about.
The state at the time can be reconstructed, together with the rules that applied then.
07 · To count forward
A certificate expires before the submission date of a tender. Count the processing time and the deadline backwards, before the folder becomes incomplete.
Deadline and decision
The agent calculates the lead time. Commissioning and submitting only follow your decision.
Formal gap
7 daysWith the current certificate the folder would be invalid on the day of submission.
History
The starting position and the check that ran stay distinguishable.
An illustration. The tender, the certificate and the processing time are invented; no application is filed.
A document that is valid today can be worthless for a later submission. So its expiry is checked against the day it will actually be used.
Not that a certificate expires soon, but that it has to be commissioned by 7 August. A date turns into a concrete point of decision.
The countercheck
Closed original records and their history are protected against unnoticed overwriting. Corrections are new, linked entries with a reason, timestamp, identity and the required approval. Technical change restrictions are one part of this. The evidence must also be assessed for permissions, completeness, retention, recovery and documented procedures.
A useful first trial includes this failure case explicitly. Fast processing alone is not success if checking and correction create more work.
The connection to the next task
Your first stage
For Evidence and audits, we choose a bounded first outcome with your team. Existing specialist systems can stay where they fulfil necessary requirements. We compare time relief, payments that can end and the cost of the new way of working.
The workshop gives you priorities and a roadmap. You can continue internally or with support from Markus Kirchmair. The choice of model and agent follows the task, with data and rules retained outside an individual chat.
Explore the workshop →Ready for the next change
The first view should show the next relevant decision. Reasoning and sources remain accessible. We leave out unnecessary features and make actual progress visible.
When a rule changes, agents can help investigate the impact, prepare the adjustment and update tests and documentation. A qualified person assesses the result and its adoption.
