cadrumo.domain.iva_compensation.filed_derivation module¶

Registry-backed filed-compensation mechanics.

This module keeps the typed evidence/result shapes and the pure carry-forward operation. Model-specific coordinates are obtained through the selected registry query boundary; this module does not declare a second vocabulary.

class CompensationCasillaDeclarations(posterior, generated, result)[source]¶

Bases: object

Selected registry coordinates needed by the carry-forward mechanic.

Parameters:

posterior (CasillaId)
generated (CasillaId)
result (CasillaId)

posterior: TypeAliasType¶

generated: TypeAliasType¶

result: TypeAliasType¶

class M303CompensationBasis(*values)[source]¶

Bases: StrEnum

Which evidence branch produced a filed-compensation observation.

GENERATED¶

RESULTADO¶

REFUNDED¶

class M303CompensationAvailableDerivation(available, generated, basis, operand_refs, operand_values)[source]¶

Bases: object

Typed history/evidence result retained for reconciliation consumers.

Parameters:

available (Decimal)
generated (Decimal)
basis (Literal[M303CompensationBasis.GENERATED, M303CompensationBasis.RESULTADO, M303CompensationBasis.REFUNDED])
operand_refs (tuple[CasillaId, ...])
operand_values (tuple[Decimal, ...])

available: Decimal¶

generated: Decimal¶

basis: Literal[<M303CompensationBasis.GENERATED: 'generated'>, <M303CompensationBasis.RESULTADO: 'resultado'>, <M303CompensationBasis.REFUNDED: 'refunded'>]¶

operand_refs: tuple[TypeAliasType, ...]¶

operand_values: tuple[Decimal, ...]¶

derive_m303_compensation_available_from_casillas(casilla_values, *, declarations, refunded)[source]¶

Apply the generic carry-forward operation to selected registry coordinates.

Return type:

M303CompensationAvailableDerivation | None

Parameters:

casilla_values (Mapping[CasillaId, Decimal])
declarations (CompensationCasillaDeclarations)
refunded (bool)
