• File repo_partial_mirror_test.go — part of check-in [6012d82bd6] at 2026-10-21 11:45:38 on branch feat/submanifest-reader — feat(sync): serve partial-mirror clones from the partial-mirror setting

  A sparse store refuses a clone its cone does not cover unless the boolean partial-mirror repository setting is on, read as fossil reads a boolean setting. It reaches HandleSync, XferHandler, ServeHTTP and repo serve alike; libfossil.SettingPartialMirror names it. Closes SC-5.3-2.
