Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Invoice contract deserialization currently accepts invalid u64 values and can return inconsistent errors for malformed input, while one expiry test will become date-dependent after December 1, 2026. Merge readiness is moderate until validation, error normalization, and the time-relative test are addressed. Sequence Diagram(s)sequenceDiagram

Validate u64 values before conversion.
int(value) silently truncates fractional values. For example, id=1.9 becomes 1, and date_created=1.9 becomes the Unix timestamp 1. Negative values also pass through despite the contract type being u64.
Reject non-integral, negative, and greater-than-2**64 - 1 values for IDs and timestamps before conversion.

Normalize contract conversion failures to InvalidRequestError.
_from_contract_dict can raise ValueError or OverflowError before cls(...) runs. For example, date_created=True raises the raw ValueError from Line 133, despite from_dict documenting InvalidRequestError for invalid input.
Catch conversion exceptions around _from_contract_dict(data) and raise InvalidRequestError consistently.

Use a relative future timestamp in expiry tests.
FUTURE is December 1, 2026. On and after December 1, 2026, test_is_expired_false_when_expires_at_in_future will fail without a product change.
Build FUTURE from the current UTC time plus a fixed duration.

Description
Implements the
Invoicemodel (src/shade/models/invoice.py) as a faithful mirror of the Soroban smart contract's invoice struct: a singledescription+amount+tokentuple, with no line items.Contract-native wire types are converted on deserialization —
u64id/timestamps to Pythonint/datetime,i128amounts toDecimal— via a dedicatedInvoice._from_contract_dict()classmethod, allowingInvoice.from_dict(contract_response)to accept a raw contract payload directly. AddsInvoiceStatus(str, Enum)(pending,paid,expired,partially_paid,refunded) and computed properties:is_paid,is_expired, andoutstanding. Both are exposed fromshadeandshade.models, adhering to existingTransfer/TransferStatusconventions.Fixes #38
