Contact integrity from memory

I’m assigning two independent readers to extract and verify the contacts in `contact.md`, then I’ll reconcile their results.

[contact.md](/workspace/contact.md) contains 12 contacts:

## Notes & Ambiguities

- **No duplicates detected** in any field.
- **John Smith** (line 20) has the name and phone bolded in Markdown, but the values are the same as the single contact row; not a separate duplicate.
- **External partner contacts** are incomplete as person contacts:
  - No email addresses are provided.
  - The “Contact Person” values are generic titles (`Manager Zhang`, `Manager Li`) rather than full personal names, and no position/title beyond “Manager” is given.
- **No other overlooked entries** were found; the blockquote lines (4–5) contain metadata only, not contacts.
- All internal contacts include `Name`, `Position`, `Mobile Phone`, and `Email`. External partners use a different schema (`Company Name`, `Contact Person`, `Mobile Phone`, `Notes`).
