Run 1 (R1–R4) in red-proof-run1.txt. R2 there HUNG (600 s timeout) — the old test blocked forever; it convicted by hanging. The test now fails cleanly; R2 re-run below.

### R2 (re-run) — no busy check
=== RUN   TestSnapshot_NeverTwoAtOnce
    dbsnap_test.go:162: second Make did not return ErrBusy at once: it ran alongside the first
--- FAIL: TestSnapshot_NeverTwoAtOnce (2.00s)
FAIL
FAIL	gitea.dooplex.hu/admin/felhom-hub/internal/dbsnap	2.007s

### R5 — main never schedules the snapshot
=== RUN   TestR173_MainSchedulesTheDBSnapshot
    r173_wiring_test.go:42: cmd/hub/main.go never calls scheduleDaily(ctx, "db-snapshot", "02:00", …) — no nightly snapshot
--- FAIL: TestR173_MainSchedulesTheDBSnapshot (0.00s)

### R6 — main has no start-up catch-up
=== RUN   TestR173_MainSchedulesTheDBSnapshot
    r173_wiring_test.go:45: cmd/hub/main.go never calls dbsnap.NeedsCatchUp — a pod down at 02:00 leaves a stale snapshot
--- FAIL: TestR173_MainSchedulesTheDBSnapshot (0.00s)
