The Matter De-identifier

Rewrite the material below so it can be discussed without
disclosing client information.

Rules:
- Replace all party names with role labels (Buyer, Seller,
  Claimant, Employer)
- Remove or generalise: entity names, individuals, dates,
  jurisdictions, dollar amounts, industries where distinctive,
  and any deal or case-specific identifier
- Convert dates to relative intervals
- Convert amounts to ranges or ratios
- Preserve every legally relevant fact and relationship
- Preserve the structure of the problem exactly

Then give me:
1. The de-identified version
2. A change log
3. A residual risk assessment: could a knowledgeable person in this
   market identify this matter from what remains?
