GPUQuerySet creation error: 'timestamp-query not supported'

When attempting to record GPU execution time with GPUQuerySet, a common failure is the error message 'timestamp-query not supported'. This occurs during device.createQuerySet if the adapter lacks the timestamp-query feature.

The goal is to determine whether this failure reflects a missing feature or an incorrect query configuration. Constraints include differing backend support (Vulkan, Metal, DX12) and the fact that the feature flag must be enabled before creating the query set. Uncertainty arises because the error can also surface if the query type is mis‑specified or if the query count exceeds limits.

To clarify the root cause, developers need to verify feature support, query limits, and API usage before creation. The following questions aim to guide the investigation:

• Does adapter.features contain timestamp-query before attempting to create the GPUQuerySet?
• Is the query type correctly set to 'timestamp' and the query count within allowed bounds?
• What fallback profiling techniques are available if timestamp-query is unavailable on a given backend?
