`CreditPole`(**data)	Pole A for the Credit dialectic — real capital side.

class babylon.engine.dialectics.credit.CreditDialectic(**data)[source]

Bases: Dialectic[CreditPole, FictitiousCapitalStock]

Real Capital ↔ Fictitious Capital.

Pole A holds the real capital stock and industrial profit rate. Pole B holds the accumulated fictitious capital claims via the FictitiousCapitalStock from economics.credit.types.

Weight semantics:: < 0: Real capital dominates (healthy production). > 0: Fictitious capital dominates (financialization).
Motion law:: Reads upstream credit growth and default rates. Weight tracks the financialization index mapped to [-1, 1].
Sublation:: When financialization index exceeds FINANCIALIZATION_BUBBLE (3.5), sublates to FinancialCrisisDialectic.

Parameters:

id (UUID)
type_tag (str)
pole_a (CreditPole)
pole_b (FictitiousCapitalStock)
weight (Annotated[float, Ge(ge=-1.0), Le(le=1.0)])
parent_id (UUID | None)
tick_created (int)
tick_updated (int)

type_tag: str

step(inputs, world)[source]

Motion law T for credit dynamics.

Parameters:

inputs (TickInputs) – Upstream outputs. Looks for credit_growth, default_rate.
world (WorldView) – Read-only world context.

Return type:

CreditDialectic

Returns:

New CreditDialectic with updated fictitious capital and weight.

sublate()[source]

Sublate to financial crisis when overaccumulation exceeds threshold.

Return type:: Dialectic[Any, Any] | None
Returns:: FinancialCrisisDialectic if financialization > BUBBLE threshold.

observe()[source]

Project credit system state.

Return type:: dict[str, Any]
Returns:: Observation dict with financialization index, total claims, profit rate.
