خطوة بخطوة

1. Ask "How many days do I have to return an item?" and get the old 14-day answer after the policy changed to 30 days.
2. Read the logs: the cited chunk id and its updated time show the stale chunk was retrieved; the model was right to use it.
3. Publish HelpArticleUpdated for the article; the consumer re-chunks, hash-compares, and re-embeds only changed chunks.
4. Planned mistake: the consumer inserts new chunks but forgets to delete old ones, so both answers are retrieved. Fix: replace the article's chunks in one transaction.
5. Ask again; the answer shows 30 days within one minute; confirm the unchanged articles were not re-embedded.
6. This prepares the freshness criterion of MID-068-LAB1.
