github-actions[bot] confirmed an updated, automatically verified Datebook marketplace snapshot in omacom/omarchy-plugin-marketplace#13263:issuecomment-6507210706. jonspinks described two-way support for Fastmail, iCloud and user-specified CalDAV servers, with app passwords stored in the keyring and conditional writes intended to avoid overwriting concurrent changes.
A later follow-up tightened deadlines for servers that slowly trickle responses. jonspinks reported whole-request limits and a 300-second per-account sync deadline, after which that account is marked offline while others continue: omacom/omarchy-plugin-marketplace#13263:issuecomment-6505549225. The reported tests cover slow headers, slow bodies and stalled accounts. Marketplace verification covers the published snapshot rather than constituting a security audit.
