ROOT CAUSE 1 (silent failure): commandToExecute = 'powershell.exe -File X.ps1' completes with exit 0 even if the script wrote to Write-Error or otherwise failed without throwing. CustomScriptExtension reports Succeeded, ARM deployment returns 0, and the previous LASTEXITCODE / $? -ne 0 checks never fire. The script appears to succeed while actual deployment work failed.

ROOT CAUSE 2 (dead error checks under set -e): jumpstart.sh and deployaksarc.sh use 'set -e' followed by 'az ...; if [[ $? -ne 0 ]]; then handle_error ...'. Under set -e, the script exits at the failed az call before the if check runs, so handle_error never executes and the EXECUTION STATUS block is never printed -- a loud ARM failure also dies silently.

FIXES:

1. Extract status helpers into shared status-reporting.ps1 / status-reporting.sh dot-sourced from both scripts (removes ~150 lines of duplication).

2. New helper 'Invoke-VmScriptDeployment' (PS) / 'invoke_vm_script_deployment' (bash) ALWAYS queries the extension instance view after the deployment and treats ProvisioningState != succeeded as a failure, even when az deployment group create returned 0. On any failure it surfaces ProvisioningState message + StdOut + StdErr from the extension substatuses (instead of just 'az command failed with exit code N').

3. Replace every 'cmd; if [[ $? -ne 0 ]]; then handle_error' with 'cmd || handle_error ... $?' so error handlers actually run under set -e.

VALIDATION:

Added three test harnesses that mock 'az' to exercise success, silent-failure, loud-failure, noisy-success, and instance-view-unfetchable scenarios -- plus an integration test that runs the helper under 'set -e' to verify the EXECUTION STATUS block is printed and the script exits non-zero on both ARM and silent-extension failures. Run with:

  pwsh -NoProfile -File aksarc_jumpstart/tests/Test-StatusReporting.ps1

  bash aksarc_jumpstart/tests/test-status-reporting.sh

  bash aksarc_jumpstart/tests/test-integration-set-e.sh

All 12 scenarios pass.
