🎯 Path-Based Segregation Strategy

In a large DevOps monorepo, running every test across every script on every commit leads to slow builds, wasted compute credits, and unnecessary CI flakiness.

Our repository strictly isolates workflows using GitHub Actions paths triggers:

on:
  push:
    branches: [ main, 'feat/**', 'fix/**' ]
    paths:
      - '2-Log-Cleanup-Script-(Delete-Files-Older-Than-X-Days)/**'
      - '.github/workflows/ci-cleanup-logs.yml'

🌐 Multi-OS Validation Matrix

All pipelines validate cross-platform compatibility across stable, pinned operating systems:

Platform	Runner Image	Validated Runtimes & Utilities
Ubuntu Linux	ubuntu-24.04	POSIX Bash, Python 3.10-3.12, Go 1.22+, PowerShell Core (pwsh), ShellCheck
Apple macOS	macos-14	BSD stat / date Bash compatibility, Apple Silicon / ARM64 execution
Microsoft Windows	windows-2022	Windows PowerShell 5.1+, PowerShell 7+, Windows path formatting

🛡️ Static Analysis & Linting Gates

1. Bash: ShellCheck (shellcheck -x) enforcing zero SC2059 format string warnings, variable quoting, and POSIX compliance.
2. Python: Ruff (ruff check and ruff format --check) enforcing PEP-8 and modern Python practices.
3. Go: go vet ./... and go test -v ./... ensuring zero race conditions and strict type correctness.
4. PowerShell: PSScriptAnalyzer rules and strict typing with [CmdletBinding()].
