Source nodes use a fixture filename in `config.fixture`; the golden-flow test
injects those rows before validation and bounded execution.
Current contracts cover monthly reconciliation, sanctions screening, a
HEICO-style current-status export, and the set-based normalization core of a
RELE-style booking workflow. Fixtures are synthetic and contain no production
records.
