+First attempt failed before the suite started — Docker Desktop wasn't
+running (`kind` could not create the cluster), and the failure was masked
+to exit 0 by a `| tail` pipe on the make invocation (no pipefail in that
+shell). Rerun with Docker started first and no pipe:
+
+```bash
+TEMPO_URL=http://192.168.0.30:3200 OTLP_ENDPOINT=http://192.168.0.30:4318 make test-e2e
+```
+
+Result: **SUCCESS — 4/4 specs (Manager smoke + both tracing Its), 219 s**,
+kind cluster auto-deleted. Run id `e2e-1787567624494810000`; the traces are
+findable in Grafana with TraceQL
+`{resource.test.run.id="e2e-1787567624494810000"}`. Both proxies reached
+`Ready` on real squid pods; the create trace carried
+`Reconcile Proxy` / `reconcile.managed` / `provider.create` /
+`status.patch` and the expected resource attrs; the deletion trace carried
+`reconcile.delete` / `provider.delete`.
+
+Worth noting: the OTLP preflight and both Tempo polls succeeded on the
+in-cluster → LAN path (kind on macOS reaches 192.168.0.30 through Docker
+Desktop's NAT), so no extra networking setup is needed on this machine.
+
+The plan's negative verification also ran: with a deliberately wrong
+endpoint (`OTLP_ENDPOINT=http://192.168.0.30:9999`) the tracing spec
+failed in the BeforeAll preflight after ~52 s with
+`OTLP endpoint http://192.168.0.30:9999 is not reachable from inside the
+kind cluster; curl output: OTLP_UNREACHABLE` — a named, fast failure
+instead of a 2-minute opaque search timeout — and teardown still deleted
+the kind cluster (`make cleanup-test-e2e` run explicitly, since a failing
+`go test` skips the Makefile's cleanup step).
