MentalSim

Predictive modeling of system dynamics

Definition

Mechanism

System 2 Simulation. Agent constructs a causal graph of the target system. It executes a 'Dry Run' of the proposed plan within that graph, inside an isolated AgentSandbox, to predict State(t+1) — toggling between fast HeuristicSnap and rigorous Deep simulation modes.

Preconditions

  1. Causal model of target system available
  2. Initial state known

Postconditions

  1. Probabilistic outcome vector generated

Invariants

  1. Builds a causal graph of the target System before running anything.
  2. The Simulation produces no side effects in the production context.
  3. Costs at most `cost_fraction` of executing the plan for real.

Risks

Failure modes

  1. Map-Territory Error

    Simulation diverges from reality (Hallucinated Physics).

  2. Overconfidence

    Agent trusts the simulation execution log more than real-world feedback.

Parameters

cost_fraction Ratio, (0.0, 0.5]
Share of real execution cost the simulation may consume before simulating is not worth it.
fidelity Enum, {Low, High}
Whether the causal graph models coarse dynamics or detailed ones.
steps Integer, [1, 10]
How far ahead the dry run looks.
