Extended the financial model from a first working slice into a controlled restructuring example, then used adversarial review to find where it could lie by omission.
Done
- Models expanded the software to handle several interacting obligations and a sequence of proposed changes.
- They added controls so a partially completed change could not be reported as a completed one.
- Review found failures in edge cases, recovery after interruption, and the treatment of impossible candidates; each was repaired and rerun.
- A separate adversarial study overturned part of its own initial classification after checking the cases more closely. The correction stayed in the record.
- The process was changed so models could no longer accept their own repairs.
- I continued to hold the boundary: this was an executable controlled example, not a validated account of household behavior.
This was the first day the model behaved like a small system rather than a single calculation. That brought a more consequential class of failure with it: several steps could each look reasonable while their combined result was impossible.
The useful breakthrough was making changes all-or-nothing. If the complete move could not be applied, the starting state remained intact. Models then had to explain the failure instead of leaving behind a plausible halfway result.
