The server-side services moved out: names, nwcpush, blossom and bridge now live in coinosv3-server. The coinos-server agent on desk extracted them (2026-10-16, after the names.json truncation of 10-15: the registrar is on SQLite there, the drift that had only ever existed on cs is committed there, and names/nwcpush/blossom on cs run from a clone of that repo, deployed by git push through its own hook). Removed here with the tests that went with them (registry-ownership-test, deepl-translate.test); the README points at the new repository and AGENTS.md says how service changes deploy now (git push from ~/coinosv3-server, never scp). feed/ and vmedia/ stay for the moment — they are in coinosv3-server too but still deploy from ~/public-feed and ~/vmedia the old way — with public-feed-cache-test. sync-blob-test spawns blossom from the sibling coinosv3-server checkout (COINOSV3_SERVER overrides) and says so when it isn't there; it passes.HEADmaster
