+.SYNOPSIS
+Queries Azure DevOps Analytics for test assembly runtimes and writes per-package weights.
+
+.DESCRIPTION
+The PackageInfo files identify the packages required by the generated PR matrix. This script
+maps those packages to their test assemblies, queries successful executions from the preceding
+24 hours, and uses a 30-day fallback query for assemblies without recent data.
+
+Each assembly receives at least a one-second weight. Package weights are the sum of their
+assembly weights and are consumed by Apply-WeightedBatching.ps1.
+
+.PARAMETER RepoRoot
+Root directory of the azure-sdk-for-net repository.
+
+.PARAMETER PackageInfoFolder
+Folder containing the PackageInfo JSON files for the generated matrix.
+
+.PARAMETER OutputFile
+Path to write the package weight JSON file.
+
+.PARAMETER PipelineId
+Azure DevOps pipeline ID to query. The default is net - pullrequest.
+
+.PARAMETER AccessToken
+Azure DevOps access token used to query Analytics.
