# PSScriptAnalyzer + Python lint — runs on every push/PR that touches code files.
# Requires PSScriptAnalyzer installed on the runner host:
#   Install-Module PSScriptAnalyzer -Scope AllUsers -Force
#
# Failures block the PR. Fix warnings with:
#   Invoke-ScriptAnalyzer -Path scripts\ -Recurse -Fix
