Simulation Layers
Documentation status: guide — see Maturity and evidence.
Simulation layers test possible consequences before action.
They are useful when an agent proposes a workflow, rule, validation path, code change, configuration change, or business decision.
Example
Proposed rule:
invoices above 10k require budget-owner approval
Simulation:
apply the rule to the last 200 invoices
count additional approvals
detect exceptions
estimate operational cost
Simulation does not commit changes. It produces evidence for validation.
