babylon.engine.systems.dispossession_events

Dispossession Event system (Feature 021, System #10).

Computes aggregate dispossession events per territory-tick, tracks value transfers between territories, and feeds rates to existing class transition engine. Publishes DISPOSSESSION_EVENT and VALUE_TRANSFER events via the event bus.

Classes

DispossessionEventSystem()

Computes aggregate dispossession and tracks value transfers.

class babylon.engine.systems.dispossession_events.DispossessionEventSystem[source]

Bases: SystemBase

Computes aggregate dispossession and tracks value transfers.

For each territory node, reads dispossession rates (foreclosure_rate, eviction_rate, displacement_rate, etc.), computes composite intensity, and publishes events. Value transfers are clamped to available wealth.

Position: #10 in _DEFAULT_SYSTEMS (after ImperialRentSystem).

step(graph, services, context)[source]

Process dispossession events for all territories.

Parameters:

graph (GraphProtocol) – Mutable world graph with territory nodes.
services (ServicesProtocol) – Service container with defines and event_bus.
context (Union[dict[str, Any], TickContext]) – Tick context with current tick number.

Return type:

None
