Artifact 879b867bb195024201d018b4cbb6bd573b7615a68cc9974c285e2181c1e84740:
Under runtime_safety (ReleaseSafe -- the shipped build) emitCloneReply reconstructed every served artifact and its delta basis just to assert a declared size. That pushed a clone round past serve's 5s per-connection deadline, which cancels mid-answer; the in-flight pread then failed and the peer got HTTP 500 on a healthy store. Issue #22.
zit verify checks the same properties on demand, which is where O(store) verification belongs.
Also names the failure server-side: serve collapses every AnswerError into a bare 500, so serveAnswer now logs which one.
Reclone verified green: wapp 1038, althttpd 1695, pikchr 2842, libfossil 17218 (18 rounds). test 2327/2327, gate, e2e 671/671, dst 6x1000. by dmestas on 2026-08-01 12:06:56.
