How it behaves

Scheduled runs only, mostly from GitHub Actions. No crawling beyond the pages a project needs.
One request at a time per site, with a pause between requests.
Respects robots.txt (user agent token tidewatch). No logins, no forms, no personal data.
User agent: tidewatch/1.0 (+https://bot.johannesotterbach.com)
Every request is signed with Web Bot Auth (HTTP Message Signatures, Ed25519). Public keys: /.well-known/http-message-signatures-directory.
