## Projects

### Public-data retention study

Independent descriptive analysis with a reproducible collection and reporting pipeline.

- Collected an eligible cohort of 1,510 public accounts in 1,519 successful read requests, with zero failed requests in the completed walk.
- Reported uncertainty and time-ordering limits; results are associations, not causal claims.
