Requirements Coverage
| Requirement | Source Plan | Description | Status | Evidence |
|---|---|---|---|---|
| SCRPT-01 | 04-01 | Generate PowerShell install script (pnputil staging + Add-PrinterPort + Add-PrinterDriver + Add-Printer + Set-PrintConfiguration) | SATISFIED | install.ps1.j2 contains all 5 cmdlets; 4 unit tests cover pnputil, idempotency, duplex, booleans; integration test confirms endpoint returns 200 with pnputil in content |
| SCRPT-02 | 04-02 | Generate PowerShell uninstall script (Remove-Printer + Remove-PrinterDriver + Remove-PrinterPort) | SATISFIED | uninstall.ps1.j2 contains all 3 Remove-* cmdlets in safe order; test_render_uninstall asserts ordering and -ErrorAction SilentlyContinue on all three |
| SCRPT-03 | 04-02 | Generate Intune detection script (registry check for printer name) | SATISFIED — with documented deviation | REQUIREMENTS.md says "registry check" but implementation uses Get-Printer cmdlet. 04-RESEARCH.md State of the Art table explicitly documents this decision: "HKLM registry check → Get-Printer cmdlet check — Both work; Get-Printer is more reliable". Intune detection contract (Write-Output + exit 0/1) is correctly implemented. |
| SCRPT-04 | 04-01 | Install script detects SYSTEM vs user context and self-elevates via UAC when run by user | SATISFIED | install.ps1.j2 lines 22-33; WindowsIdentity::GetCurrent(), IsSystem, IsInRole(Administrator), Start-Process -Verb Runas; UAC guard skips elevation when running as SYSTEM |
| SCRPT-05 | 04-01 | Install script includes 64-bit WOW64 relaunch guard for Intune's 32-bit execution context | SATISFIED | install.ps1.j2 lines 12-16; PROCESSOR_ARCHITECTURE + PROCESSOR_ARCHITEW6432 check + SysNative relaunch; positional test confirms guard appears before pnputil |
Note on SCRPT-03: The requirement description says "registry check" but the research document (04-RESEARCH.md) explicitly supersedes this with Get-Printer cmdlet approach, noting it is more reliable than the HKLM registry path approach. This is a planned deviation documented before implementation. The functional contract (Intune detection: Write-Output + exit 0 when present, exit 1 when absent) is correctly satisfied.

Test Suite Results
tests/test_script_generator.py — 14/14 passed
Full suite — 75/75 passed (no regressions)
Human Verification Required
1. WOW64 Relaunch — Live 32-bit Context
Test: Launch powershell.exe (x86) on a Windows endpoint and run the generated install.ps1
Expected: Script detects 32-bit process, relaunches under SysNative 64-bit PowerShell, driver staging succeeds
Why human: Requires a physical 32-bit PowerShell host; cannot emulate WOW64 in unit tests
2. UAC Elevation Prompt — Standard User
Test: Run install.ps1 as a non-admin standard user on a real Windows desktop Expected: UAC elevation dialog appears; after approval, printer installs successfully Why human: Requires interactive desktop session with a standard user account
3. Intune Detection Contract — Real Intune Enrollment
Test: Deploy a printer as an Intune Win32 app using the detect.ps1 as the detection script Expected: Intune marks the app as "Installed" after seeing Write-Output + exit 0 Why human: Requires Intune tenant, enrolled device, and deployed Win32 app — not automatable
Summary
Phase 4 goal is fully achieved. All 12 observable truths are verified against actual code, not just SUMMARY claims. The implementation is substantive: templates are real PowerShell (not stubs), render functions use actual Jinja2 template rendering with duplex translation and boolean conversion, and all three API endpoints have complete ORM validation with proper 404/422 error paths.
The three human verification items are real-world deployment concerns that cannot be automated (WOW64 live context, interactive UAC, Intune tenant). These are flagged in the validation strategy document and are expected at this phase.
The SCRPT-03 "registry check" wording in REQUIREMENTS.md is a minor description inaccuracy — the implementation correctly uses Get-Printer per the research document's recommendation, which explicitly documents this as the preferred approach over the registry path. The functional Intune contract is satisfied.
