Inspect mirror scale planning limited availability headers.

Inputs. No path or query fields are required. No request body is required.

Outputs. See each status below for its media type, schema and headers. A missing record or unavailable capability is not a successful empty result.

Errors. HEAD returns headers without a body. Use the HTTP status and Retry-After.

Rate limits. Public read budgets apply by client IP and route group. This operation can have a smaller route-specific budget. Read Retry-After on 429 or retryable 503 responses.

Example setup. This route has no documented success response. The example shows how to inspect its redirect or refusal; it does not promise an available capability.
