"""Привязка документов к версиям консолидации (spec documents-api «Подтверждение документа», «Подхват документов при
создании версии и расширении периметра»; audit-trail `CONSOLIDATION_STATUS_CHANGE`; design D-5, D-6, D-9; рулинги
R-1 — ключ замены с признаком нарастающего, R-2 — гонки потерянной привязки, R-3 — `FOR NO KEY UPDATE` документа).

Сценарии подтверждения и подхвата — поверх `seeded`/`auth_client` (транзакция теста). Гонки — на `committed_*`
(настоящие параллельные транзакции, таймаут 5 с): подтверждение ∥ правка периметра в обе стороны, создание версии ∥
подтверждение в обе стороны и совместимость блокировки документа подтверждения со вставкой привязки.
