Merge Risk: 🟡 Moderate · up to Two Pods that start at the same time with the same private-registry credentials can cause one of them to fail permanently. Some image errors can also be treated as capacity shortages, which temporarily excludes healthy RunPod placements. Fix both before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Classify image-pull failures before capacity failures, or narrow the capacity patterns.
The capacity case runs before the image-pull case. It matches the generic substrings "not available" and "unavailable". A create rejection such as "image not available" or "manifest unavailable" therefore gets wrapped with provider.ErrNoCapacity, not provider.ErrImagePull. ClassifyProvisionError then installs a block for that accelerator, tier, and region. One Pod's bad image then excludes a healthy candidate for every other Pod until the TTL expires. The comment on Lines 257-259 names exactly this failure as the thing to prevent.
Move the registry/image case above the capacity case. Alternatively, drop the bare "not available" and "unavailable" patterns and keep only the specific capacity phrases.

🌐 Web query:
Does RunPod REST API POST /containerregistryauth reject a duplicate name?
💡 Result:
Yes. RunPod’s API documentation says the `name` must be unique, so creating another registry auth with an existing name should be rejected. The docs I found don’t specify the exact HTTP status code or error body. [1]

Handle concurrent EnsureRegistryAuth calls.
EnsureRegistryAuth lists and then creates without synchronization. If two Provision calls for the same credentials overlap, both can miss the matching object. RunPod requires unique names, so one create can fail. The error reaches vnode as ProvisionFailed, and vnode stores the failed state without retrying.
Re-list after a failed create and reuse the matching object:
🐛 Proposed fix
var created registryAuthResponse
if err := c.do(ctx, http.MethodPost, registryAuthPath, body, &created); err != nil {
+ // A concurrent Provision may have created the same content-addressed object.
+ var again []registryAuthResponse
