DRILL 2: one real edge and one deliberately failing edge for the unattended-night spike

uptime-kuma 2.5.0 -> 2.5.1 : a real one-step edge (scenario F, must succeed)
vikunja 2.6.0 -> alpine:3.20 : a C3-class negative control (scenario G, must HOLD)

Both reverted in this same session. No customer box runs either app.
