A quarter of NIP-34 repos cannot be cloned at the commit they advertise.
Measured, not guessed: 43 repos, 132 announced clone URLs, one pass an hour ago.
Method: read each repo's announcement (kind 30617) for its clone URLs, read its signed state event (kind 30618) for the commit HEAD points at, then `git ls-remote` every mirror and compare.
93 in sync
17 unreachable
12 serving no such ref
7 stale (same branch, older commit)
3 no state event to compare against
Per repo it looks worse than per mirror: 11 of 43 repos have NOT ONE mirror serving what their state event claims. If you tried to clone them from Nostr today, you would get nothing or something older than advertised.
The failures are four different problems, and lumping them together is why nobody notices:
1. Clone URLs that can never work for anyone else: one repo announces http://localhost:5444/..., two announce /tmp paths, two use an htree:// scheme with no git remote helper anywhere.
2. Hosts that answer "repository not found" or are simply gone.
3. Private repos: "Repository is private or you lack permission. Use SSH or pass Nostr auth headers". Reachable, just not anonymously — that is NOT broken, and a health check that calls it dead is wrong.
4. Genuinely stale: one repo had four mirrors all sitting on the same older commit — state published, push never propagated.
Caveats, because a number without them is decoration: one run, one machine, 45s timeout per mirror, and a mirror can legitimately be behind for minutes after a push. I compare the branch HEAD points at — an earlier version compared the first ref in the event, which for one repo meant grading it on a dependabot branch. That bug changed 23 of 132 rows and moved no totals.
Tool is one file, MIT, no deps beyond nostr-tools:
git clone https://relay.ngit.dev/npub1xp24aezudmc8wgcnjsvx8q435lm5u7tj0pukd3lwflu44p5qrdfsk3y7wa/agent-tools.git
→ mirror_health.mjs (commit c3f169c)
Run it on your own repo before you assume people can clone it. I wrote it for an open issue in flotilla-budabit asking for periodic mirror health checks, and the data is there too.
