📝 WalkthroughWalkthroughAdded shared Prometheus metrics for cloud API errors and managed BGP peers. AWS, Azure, and GCP integrations now record operation-specific failures and managed-peer counts. Reconciliation and cleanup update peer gauges. Tests cover API error classification, peer counts, and metric resets. Suggested reviewers: Merge Risk: 🔵 Low · up to GCP cleanup can report a nonzero managed-peer count after peers are successfully removed if subsequent NCC cleanup fails, producing misleading operational metrics. The change is otherwise bounded, but this metric-correctness issue should be addressed before merge. 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

58-62: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winReject endpoints without a resolved availability zone.
Line 54 accepts a missing subnet-to-zone mapping as
"". Lines 58-62 then create an empty-zone peer group. Reconciliation can associate that endpoint with router nodes that also have an emptyZone.Return an error unless the endpoint subnet resolves to a non-empty availability zone.
Proposed fix
- az := subnetAZMap[subnetID] + az, ok := subnetAZMap[subnetID] + if !ok || az == "" { + return nil, fmt.Errorf("endpoint %s has no resolved availability zone", epID) + }As per path instructions, validate at trust boundaries with allow-lists, not deny-lists.

Update — multi-cloud platform metricsThis PR now adds shared Prometheus metrics for AWS, Azure, and GCP (not a single-cloud shape):
Metrics are registered in Follow-up for #74: Could you take a look at #52 when you have a chance? I'm also happy to adjust anything that blocks #74. Thanks! |

Looks good, just a small suggestion for debugging

Summary
Add Prometheus metrics for cloud platform reconciliation across AWS, Azure, and GCP.
cloud_api_errors_total{platform, operation}— counts cloud API failures by platform and operation (discover,peer,node_forwarding; GCP alsoncc). Does not count local validation or configuration errors.cloud_peers_managed{platform}— number of BGP peers after a successful reconcile; set to zero when cleanup clears peers.Metrics register on controller-runtime's existing metrics endpoint (
internal/platform/metrics.go).Changes
