May need to review a prior purchase, payment sequence, or account history after data retention changes.

What pulls against what

  • retention compliance vs. historical usability
  • fixed cutover vs. verification depth
  • financial reconstruction vs. data minimization
  • managed archive safety vs. unified data semantics

What is at stake

The retention path is fixed and irreversible. The task is to prove essential downstream interpretations survive before historical events are compacted

Why Affirm

At Affirm, plan records often need to remain understandable across the life of a customer relationship.
