Supersedes the -dirty row from the previous commit by the ledger's own
append-only / latest-wins convention (lib/status.py latest_by_test): nothing
is rewritten, a newer row simply outranks the older one.
runs/20260913T014923Z-9d0814a vpn-killswitch (L3) proven env=prod
git_sha 9d0814ae... (CLEAN — resolvable, so the freshness check passes)
Fault injection against LIVE prod, gateway k3s-prod-3. Timeline (UTC):
01:49:27 tunnel-stop Job applied
01:49:31 Job succeeded — host vpn-egress-tunnel STOPPED, tun0 gone
01:49:31..01:51:01 vpn-class blackholed for 8 consecutive polls, NO response
of any kind; internet-class unaffected on the WAN
01:51:02 self-healing finally: tunnel-restart Job
01:51:05 kubectl wait confirms the host brought the unit back
01:51:04 egress-uplink label AND the BPF egress map both move 134 -> 139
(measured independently, out of band, during the run)
01:51:08 vpn-class egress back on PIA 158.173.241.11
RECOVERY WAS UNAIDED and took ~3s from tunnel-up to a re-steered datapath —
far inside the ~2-minute convergence timer, so the EVENT-DRIVEN up-script
path did the work, not the timer backstop. This is the half that was
previously unprovable: before the egress-uplink label, Cilium held the stale
ifindex and vpn-class egress never came back.
WHAT THE NO-LEAK ASSERTION DOES AND DOES NOT PROVE: it proves vpn-class
fails CLOSED (zero packets out, never the WAN IP). It does NOT credit the
host nftables backstop, which provably cannot fire for pod traffic —
bpf_redirect() skips netfilter. Stopping the tunnel removes tun0 and Cilium
drops on its own because the cached egress ifindex is unusable. Fail-closed
is real; the mechanism is Cilium's drop, as the test header now says.
