Multi-Tenant Cluster Outage

Restore one tenant's portal without breaking the healthy tenant

Two tenant portals share a common catalog API. Tenant B is healthy. Tenant A is down. Your job is to restore Tenant A so its portal loads and its /api/status route works again.

Not everything that looks suspicious is part of the outage. The challenge is to debug traffic flow across namespaces and shared infrastructure instead of blindly rewriting manifests.
