10## How it works
11
12A daily cron job:
13
141. Fetches `state.json` listing ~2900 known PDSes with signup status
152. Syncs open/closed status to a SQLite database
163. Enriches a batch of 20 servers per run (health, describeServer, listRepos,
17 geo-IP)
184. Checks for the latest PDS version from the `bluesky-social/pds` GitHub repo
19
20The web interface shows open servers with sortable columns, version badges, and
21trust signals.
