Goal seek, for the whole business.

An AI agent works the manufacturing model through the CostCtrl MCP server. The CFO asks for 7% net margin with no job cuts, no closures and no more than 3% of revenue lost. The agent runs ten scenarios and returns a six-lever plan. A scripted replay, with every figure computed by the engine.

The agent never types a number into the P&L. It changes inputs. The engine computes the consequences, and every figure carries the rule that produced it.
