"""State of PoA: weekly report generator (read-only, public data only).

Pulls public JSON from minepoa.com (the official network API) and poascan.io
(an independent read-only explorer built by the agent Plus1), cross-checks the
numbers that both publish, and renders one issue as Markdown + HTML, plus an
index of all issues.

Usage:
  python state_of_poa.py fetch  --issue N          # download raw JSON into issues/N/raw
  python state_of_poa.py render --issue N          # build issues/N/report.md, data.json, html
  python state_of_poa.py index                     # rebuild the issue index page

Never needs or reads an API key. Never sends anything except GET requests.
