Drop the standalone IBAC sidecar (forked authbridge image + Envoy + iptables init container) in favor of patching the operator-injected authbridge sidecar's plugin pipeline. The new flow appends a2a-parser (inbound) and inference-parser/mcp-parser/ibac (outbound) into the operator-managed authbridge-config-<agent> ConfigMap, and waits for the sidecar's filesystem-watch hot-reload to swap pipelines. Also wires --ibac to authBridgeEnabled=true in the kagenti API call so the operator injects the sidecar (and creates the ConfigMap) in the first place. Removes envoy-config.yaml and patch-deployment.yaml (legacy stack); adds ibac-patch.yaml (envsubst template), ibac-merge.py (idempotent ConfigMap merge with --prompt-file), and wait-for-reload.sh.

Stale leftover from before the migration commit; the flag no longer injects an Envoy overlay sidecar. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Kelly Abuelsaad <kna@us.ibm.com>
The kagenti-deps otel-collector binds OTLP/HTTP on 8335 (and gRPC on 4317); nothing is listening on 4318, so requests to 4318 return 503 and crash the agent's strict OTEL startup probe. Assisted-By: Claude (Anthropic AI) <noreply@anthropic.com> Signed-off-by: Kelly Abuelsaad <kna@us.ibm.com>

Notes
ibacplugin (e.g.localhost/ibac-sidecar); the operator's defaultauthbridge-envoy:v0.5.0-rc.3does not include it and will logreloader: reload failed ... unknown plugin "ibac". Document or wire the image override before merging if this is intended for general use.
