The previous commit (89524d4) only captured the file rename - a git
add with one stale/invalid pathspec aborted before staging the actual
content, and the resulting empty diff wasn't caught before committing.
This commit has the real changes described in that one's message:
EXPECTED_VLAN50_IP/NET_RAW on the guard init container, REQUIRE_AUTH
dropped to false with ALLOWED_IPS removed entirely (broken as drafted
- see the file's own header for why), sync-wave 3 annotation, and the
README updates dropping the now-unneeded secret-script references.

Diagnosed the vlan50-canary FailedCreatePodSandBox->net1-timeout failure
as a stale Pod artifact of the Multus DaemonSet rollout race (sandbox
created via a transient daemon/shim state mid-rollout; the current,
fully-settled daemon's own logs show no ADD for that UID, only a DEL).
No defect found in 02-daemonset.yaml or 10-nad-vlan50.yaml; both are
unchanged.
Independent of that diagnosis, harden the shared guard script per
review: print safe interface/address/route diagnostics before every
FATAL exit; validate net1 actually carries the workload's expected
static /24 address rather than just existing; add arping-based
duplicate-address and gateway-reachability checks before installing
the net1 default route (exit-code semantics verified against arping's
own source). Requires EXPECTED_VLAN50_IP and NET_RAW (for arping's raw
ARP sockets) on every consumer - wired into 20-canary.yaml now,
qbittorrent.yaml/jdownloader.yaml need the same when they're migrated.
Document the canary's Pod lifecycle: restartPolicy: Never means a
Failed canary never reruns on its own, and Argo "Synced" only reflects
manifest match, not runtime success - recreate it (new UID) after any
Multus/CNI change before trusting its result. Recommend keeping it a
manually recreated, controller-less Pod rather than a Job/Deployment,
since unattended auto-retry risks a duplicate-address race on its
static .100 IP - the exact class of bug this diagnosis just walked
through.

CRD, RBAC, thick-plugin DaemonSet (nik-debian only, k3s CNI paths,
digest-pinned), the VLAN 50 NAD (macvlan bridge on enp1s0.50), the
shared pod egress-guard script, a temporary canary pod, and the
not-yet-deployed browser-vpn-proxy workload (kept in reserved/, outside
this Application's non-recursive source path).
Referenced by argocd/apps/multus.yaml (already pushed) but not deployed
by it — that Application has no syncPolicy.automated, so this still
needs an explicit selective sync per resource.
