# Filter display clone URLs

Sidebar clone list for NIP-34 announces: keep forge `source`, primary git host,
and every host on the **Push allowlist** (`GRASP_SERVERS_FOR_PUSHING`). Hide bare
IP mirrors and random third-party GRASP hosts.

**Do not** collapse to “primary only” when primary is present — that hid
shakespeare / gitnostr / ngit even though Push advertises them (fixed Aug 2026).

If you inject `isGraspDomainForPushing`, pass the **production push list** (`git.gittr.space`, ngit, gitnostr.com, shakespeare — **not** `relay.gittr.space`). The relay hostname is wss only; advertising it as a clone host 404s on git fetch.
