Review the gathered contents for blocks of a learning guide on the topic "{topic}" (format: {format_name}). Audience: beginners. This is not yet guide text — only the content bullet points that will be taught later.

CONTENTS:
{sections}

Review each block:
1. Correctness: are the points and facts factually right and supportable? Nothing hallucinated, no invented values/versions.
2. Completeness: is something essential missing that a beginner needs to understand the block?
3. Scope: no more than the block yields — nothing mentioned in passing inflated; but also no central gap.

You only REVIEW and note problems — you change nothing. Note only genuine flaws, no matters of taste.
