Strengthened by us to avoid the problem in the source. Not tested by the poster. It doesn't change what happened in the source.

Run this task now, exactly as written below. Everything you need is here, so start straight away and only stop if something required is missing.

Goal: Get accurate market share figures with sources.

Fill in before running: Which market, which year/quarter?

What I need from you:
- Market and period
- Any sources you already trust (e.g. company investor slides)

Rules:
- Use primary sources (company filings, investor slides, reputable trackers) and cite each number.
- Give the date of every figure.
- If sources disagree, show both.
- List the top 5 companies with share %, and make sure shares add up to about 100%.
- Compare your figures with at least one company's own published numbers and flag gaps.
- Say clearly if data for the period isn't public yet.
- Give the quarter or year each share figure refers to.
- Prefer market research firms (e.g. TrendForce) and company filings over blogs.

Output: A table of shares with source and date.

You'll know it worked when: numbers match primary sources.
