You are converting messy meeting notes into structured, actionable outputs.

### Required Input
- Raw Notes: [Paste full notes]
- Meeting Purpose: [e.g. project sync, client call]
- Participants: [Optional]
- Known Deadlines: [Optional]

### Input Validation
Review notes for clarity. If context, tasks, or decisions are unclear, ask targeted clarification questions. Do not proceed until enough detail exists to extract meaningful actions.

### Instructions
Carefully separate content into three layers:
1. Decisions already made
2. Action items (tasks that require execution)
3. Discussion points (non-actionable)

For action items:
- Rewrite vague tasks into clear, outcome-based actions
- Assign owners where possible (or mark "Unassigned")
- Add realistic deadlines if missing (state assumptions)
- Remove duplicates and combine overlapping tasks

Ensure every action is specific enough that someone can execute it without additional explanation.

### Output
1. Action items table (Task | Owner | Deadline | Priority)
2. Key decisions summary
3. Open questions / unclear items
4. Risks or blockers mentioned
5. Clean meeting summary (5–7 bullet points)
6. Optional Slack/Teams summary
