The Transaction Timeline Builder

Build a transaction timeline.

Contract date: [DATE]
Closing date: [DATE]
Financing: [TYPE]
Contingency periods: [LIST FROM CONTRACT]
Parties: [LIST BY ROLE]

Produce:
1. A dated timeline, working backwards from closing
2. Every deadline with its owner
3. Critical path — what blocks what
4. Buffer analysis: where the schedule is tight
5. The five things most likely to cause delay in this deal type
6. A client-facing version showing only what they need to do
7. Reminders to set and when

Rules:
- Use only the dates and periods I supply
- Do not assume any standard period — every jurisdiction and
  contract differs. Mark unknowns as [CONFIRM FROM CONTRACT].
- Flag anything where the calculation method matters (business
  days vs calendar days) as [CONFIRM]
