site.kind: pt / public_bt / rss_feed / torznab. Each kind declares the acquisition modes it may support (search, list, rss, detail, login, userinfo); a site's effective capabilities = kind ∩ site definition. torznab only defines TorznabSiteConfig and cannot be added yet. Migration 0055: generic_rss sites become rss_feed, the rest pt; feeds without a site are grouped by host into new custom RSS source sites (cursor window and conditional headers cleared so the next fetch writes releases). User DB read-only dry-run: 0 orphan feeds. Co-Authored-By: Claude Opus 5.5 <[email protected]>
