# Benchmark Compatibility Delta Spec

## MODIFIED Requirements

### Requirement: Enriching Benchmark Submission Payload
The system MUST include the generated `machine_hash` and extended user-mode telemetry fields (`display_server`, `resolution`, `refresh_rate`, `desktop_environment`, `storage_type`, `vulkan_driver`, `cpu_temp_start`, `cpu_temp_max`, `cpu_temp_delta`, `gpu_temp_start`, `gpu_temp_max`, `gpu_temp_delta`) in the benchmark submission JSON and CSV payloads sent to PascubeDB.

#### Scenario: Submit results with machine hash and extended telemetry
- **WHEN** preparing the benchmark submission payload
- **THEN** the system attaches `machine_hash` and all 6 extended telemetry variables (with measured values or `"N/D"` fallbacks) into the JSON and CSV payloads before spawning the submission thread.
