debugging-and-error-recovery

A disciplined general debugging workflow for PowerShell/DSC code, builds, and tests: reproduce, localize, reduce to a minimal case, fix the root cause, then guard with a regression test. Stop-the-line on a red build; fix causes not symptoms; never swallow an error to make a failure disappear. A language-neutral method with PowerShell tactics (-ErrorAction Stop, try/catch, Get-PSCallStack). USE FOR: debugging, how to debug, systematic debugging, reproduce the bug, isolate the failure, root cause analysis, minimal repro, bisect a regression, flaky test, intermittent failure, error handling strategy, stop the line, regression guard, works on my machine, heisenbug. DO NOT USE FOR: DSC resource failures on a node (use dsc-troubleshooting), WinRM connectivity (use winrm-troubleshooting), Sampler build or Pester failure diagnosis (use sampler-build-debug), whether a long job is stuck (use long-running-job-monitor), security review (use agent-security-review).
