Friction: first source module origin was /tmp/issue-9853-fixture/sub (local); configured .gitmodules destination was git://127.0.0.1:19453/sub. Local source origin caused reuse eligibility to be skipped.
Observed received pack bytes: 16782544; <1MiB: FAIL
Fixture source origin subsequently aligned to git://127.0.0.1:19453/sub; repeat blocked by ECONNREFUSED 127.0.0.1:14045. Lead-owned server not restarted.
