Working group, review cadence, and version control.

## 10.1 Customer Working Group [#101-customer-working-group]

Greenpixie engages a customer working group to provide input on methodology scope, coverage requirements, and reporting needs. The group's scope includes cloud provider and service coverage, output granularity, validation expectations, reporting integration, and alignment with customer sustainability frameworks. Feedback informs prioritisation of methodology enhancements and coverage.

## 10.2 Routine Review [#102-routine-review]

The methodology is subject to periodic review to ensure continued alignment with developments in cloud provider instance catalogues, processor and accelerator platforms, emissions accounting standards, and published research.

## 10.3 Material Changes [#103-material-changes]

Material changes to the methodology, including changes to the processor matching logic, the memory module power reference, the drive power reference, the operating point, or the treatment of burstable sizes, are documented, reviewed internally, and reflected in updated versions of this document.

## 10.4 Version Control [#104-version-control]

Each published version of this methodology is assigned a version number. Changes between versions are documented to support audit and review requirements.
