Overall this is a solid implementation of the browser-based binding flow. The tabbed UI approach with multiple methods (One-Click, Already Connected, Bundle, Manual) gives users good flexibility. A few items to address before merging:

Security

/api/konnector-manifests is unauthenticated - This endpoint is registered without RequireAuth. Is this intentional? If so, consider rate limiting since it reveals deployment details.

ClusterRole grants full cluster-admin - The konnector ClusterRole uses apiGroups: [""], resources: [""], verbs: ["*"]. Worth documenting why this broad access is required, or scoping it down if possible.

Consumer kubeconfig handling - The security note in the UI is good. Please confirm the kubeconfig bytes aren't logged anywhere (e.g., in error messages or debug logs).

Bug

Missing cluster parameter in handleConsumerStatus - At handler.go:189, the call to GetConsumerStatus passes identity and params.ClusterID, but looking at the implementation, it seems like the namespace lookup should work. However, double-check that the cluster context is being used correctly throughout the flow.

Suggestions

• Duplicate konnector definitions - The YAML template in handleKonnectorManifests and the Go structs in ensureKonnector define the same resources. Consider generating one from the other to avoid drift.
• Empty bindingName in non-UI flows - exportRequestName is only set for UI flows, so the response will include an empty BindingName for CLI flows. May want to omit the field entirely with omitempty behavior or always populate it.
• Compiled assets in PR - The web/dist/ changes could be generated in CI rather than committed, reducing diff noise.

Nice work on the polling logic with seenOnce to handle cache lag, and the idempotent create-or-update patterns throughout.

Keeping it as a draft again, need to clean the code a bit and put a write-up
