cadrumo.application.calculations.iva_compensation_annual_partition module¶

Modelo 390 IVA compensation annual partition source resolver.

The resolver reads a RegistrySnapshot for the annual Modelo 390 revision, inspects its ModeloRevision bindings owned by IVA_COMPENSATION_ANNUAL_PARTITION, and derives the two annual compensation partition amounts from filed Modelo 303 ObservationEnvelopePayload records.

period_state_from_303_envelope(envelope, *, operation)[source]¶

Build one FIFO state from a validated filed Modelo 303 envelope.

Return type:

IvaCompensationPeriodState

Parameters:

resolve_iva_compensation_annual_partition_binding_values(revision, envelopes, *, filing_year, operation)[source]¶

Resolve Modelo 390 annual compensation bindings from filed M303 states.

Parameters:

revision (ModeloRevision) – The annual Modelo 390 ModeloRevision whose partition bindings declare the target output slots.
envelopes (tuple[ObservationEnvelopePayload, ...]) – Filed, already-normalized Modelo 303 ObservationEnvelopePayload records used to reconstruct the compensation FIFO state.
filing_year (int) – Annual filing year used to select same-year Modelo 303 observations.
operation (PinnedAuthorityOperation) – Caller-owned generation-pinned authority operation used to validate the source revisions.

Return type:

dict[TypeAliasType, Decimal]

class IvaCompensationAnnualPartitionSourceResolver(*, operation, repository, registry_snapshot=None)[source]¶

Resolve Modelo 390 boxes 97 / 662 from the IVA compensation FIFO partition.

Parameters:

resolve(context)[source]¶

Resolve the Modelo 390 boxes 97 / 662 IVA compensation FIFO partition for context.

Return type:: CalculationSourceResolution
Returns:: An empty resolution when the revision declares no such requirement, a degraded resolution on repository failure, or the resolved CalculationSourceResolution.
Parameters:: context (CalculationSourceContext)
