Change detection needs a decision trail, not just a diff

Описание и применение

Практический подход к обнаружению изменений требует формирования цепочки принятия решений, включающей исходные и текущие нормализованные записи, ссылки на источники, временные метки извлечения, явный статус и правила сравнения.

Задача

A changed field is only the beginning of a useful operational signal. Before a team acts on it, they need enough context to tell whether it is a real source change, a missing value, a failed retrieval, or a mismatch in market, variant, or source scope.

Результат

A practical decision trail approach to change detection provides sufficient context for teams to understand and act on changes appropriately, distinguishing between real source changes, missing values, failed retrievals, and scope mismatches.

Рабочий процесс

• Run the collection step separately from comparison and delivery
• Validate a small sample against original source pages before adding schedules
• Add downstream automation only after successful validation
• Treat important alerts as review cues, not final instructions

Доказательства

A practical decision trail keeps the prior and current normalized records, their source references, retrieval timestamps, an explicit status, and the comparison rules that produced the delta.

For monitoring workflows, run the collection step separately from comparison and delivery. Validate a small sample against the original source pages before adding schedules or downstream automation.
