## Update Script Maintenance Report

Date: 2026-03-04

- Ran updater: `python population_estimates_flow.py`.
- Root cause: upstream UN source URL in pipeline currently returns HTTP 404.
- Fixes made:
  - Added first monthly + manual GitHub Actions workflow with `contents: write` and reproducible `dataflows` install.
  - Kept existing pipeline logic unchanged to avoid introducing unverified source migrations.
- Validation summary: updater invocation is wired in automation; data refresh remains blocked by upstream endpoint availability.
