3. The Agent's Behavior (Ternary Logic)

Movement and state change governed by Three Social Rules—the logic gates of behavior

ABM Rule (The Code) Agent's Action Outcome on the Map
RULE 1 Proximity Propagation The agent's state (vulnerability) increases if nearby agents are also vulnerable (Local State). Causes a clustered, localized spread of the "toxic cloud."
RULE 2 Network Amplification The agent influences, or is influenced by, another distant agent linked through a coded social tie (Intermediary State). Creates "jumps" or non-contiguous pockets of vulnerability across the map.
RULE 3 Historical Vulnerability The agent is penalized or locked into a higher state of risk if its location overlaps with a historical policy boundary (Initial State). Ensures the INITIAL STATE ≠ ZERO by preventing agents in redlined zones from easily becoming "un-vulnerable."
The final output—the KDE Visualization—is not a map of the agents themselves, but a heat map (the "toxic cloud") generated by their collective, accumulated positions after 70 years of simulation. The agent is the mechanism of proof.
