Below, for each block of the topic "{topic}", are the subblocks found. Return the **cleaned** final list per block.

{source}

FOUND SUBBLOCKS (two groups per block):
{blocks}

The groups:
- **Consensus (≥2 finders):** found independently multiple times — keep by default. Remove only fabrications/duplicates.
- **Uncertain (1×):** named by only one finder — **scrutinize strictly**. Include an uncertain entry ONLY if it is **clearly backed by the source AND a standalone point**. When in doubt, leave it out.

Rules:
- **Evidence check (important):** Check each subblock against the source. **Discard whatever is NOT backable in the material or clearly invented** — fabricated bounds, formulas, values, or claims not actually in the source. With a source file: check against the file. Without a source (pure topic): keep only established standard knowledge, drop the doubtful/false.
- **Merge duplicates:** Subblocks that state the same point in other words are ONE. Keep the clearest, drop the rephrasings. (e.g. „Broadcast Mode verfügbar" and „Broadcast-Modus aktivieren" → one.)
- Keep all technically **DISTINCT** and backable sub-points in full — leave out nothing essential.
- Discard whatever is too fine-grained, at the edge of the topic, or technically doubtful.
- Each point atomic (one statement). Copy kept points VERBATIM, do not rephrase, invent nothing.
- The count follows the difficulty: better few distinct than many redundant points.

Write ONLY the file {out_path} — one block marker per block (title EXACTLY as above), with the final subblock list below it:

<!-- block: Exact block title -->
- Subblock
- Subblock

Write the marker line exactly like this. Every block must appear. No text outside the blocks.
