Subject: [PATCH] fix(neuron-prod): add allow-dharma-ingress NetworkPolicy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The neuron-prod namespace runs a default-deny-all NetworkPolicy and
explicit allow-ingress policies for every legitimate service:
allow-mcp-ingress, allow-rest-ingress, allow-marketing-ingress,
allow-daemon-ingress, allow-engram-ingress. There was no equivalent
for dharma — so every request that arrived at Traefik in kube-system
got 502'd at the Service-to-pod hop, even though the dharma pod
itself was healthy and the IngressRoute was correctly defined.

The previous attempt to fix the 502 (PR #1) removed an unrelated
nonexistent certResolver from the IngressRoute. That was real but
not sufficient — the Traefik routing layer was healthy after that
change, but the Service-to-pod NetworkPolicy hop was still denied.

This adds allow-dharma-ingress mirroring allow-mcp-ingress: accepts
traffic from kube-system (Traefik) and from the neuron-prod
namespace itself.

+# ── dharma: accept from Traefik (kube-system) and neuron-prod namespace ──────
+# The dharma pod was healthy and the IngressRoute was correct, but cross-
+# namespace ingress from kube-system (Traefik) was denied by default-deny-all,
+# so every external request landed at Traefik and bounced back as 502. This
+# allow rule mirrors `allow-mcp-ingress` and brings dharma into line with the
+# other neuron-prod services.
