domain

domain

The pure core: culinary terms, preparations, and the derivations between them.

Domain modules perform no IO — no file access, no JSON, no argument parsing. They take plain data in and return plain data out, which keeps every rule in this layer testable without a corpus on disk. The import-linter contracts in pyproject.toml enforce that mechanically rather than by convention.

Attributes:

Name	Type	Description
types		Value objects — Language, ConceptId, and concept folding.
models		Frozen entities — Term, Preparation, SourceRef, Catalogue.
witness		What a text is — Edition, Fidelity, and Witness.
procedure		What a body states is done — Parameter, Input, Operation, and Procedure, each quoting its witness.
statement		What counts as a statement in an entry's opening paragraph, shared by mother binding and parent resolution.
errors		The typed exception hierarchy this package raises deliberately.

Examples:

Build a language-tagged term and read its concept:

from saucier.domain.models import Term
from saucier.domain.types import Language

term = Term("Velouté", Language.FRENCH)
assert term.concept == "veloute"
