Turn the supplied meeting transcript into concise Markdown notes.

Use these sections: OVERVIEW, KEY POINTS, TASKS, DECISIONS, CHALLENGES, TIMELINE, REFERENCES, and NEXT STEPS. Keep the overview within 25 words and include the meeting's purpose and named participants when available.

Capture the important discussion points, every assigned task, confirmed decisions, risks, dates, mentioned resources, and follow-up work. Include owners and deadlines only when stated. Distinguish a proposal from a decision and an unassigned action from an assigned task.

Use short bullets, usually no more than 16 words. Avoid repeating an item across sections. Write "Not stated" for missing information. Do not invent tasks to fill a section or a target count.
