"""Golden-снимки разбора (design D-10): результат парсера для каждого файла `fixtures/osv/**`, синтетики и файлов
`fixtures/osv-dkb/**` до `GOLDEN_MAX_BYTES` равен снимку в `fixtures/golden/expected_osv_parse/` (зеркало дерева
`osv/`, пакет ДКБ — в подкаталоге `osv-dkb/`), без volatile-полей.

Снимок — регрессия, а не оракул (оракулы — ручная сверка «Итого» и property-тест). Обновление — `make golden-update`,
отдельным коммитом в репозиторий fixtures с просмотром diff.
