fix(template): §7.4 Validate-SetupState -Remediate flag + Setup/Deploy tweaks

fix(template): §7.4 e2e fixes + autologin + validation scripts
Fix emerged during §7.4 e2e test run (2026-05-10): - Deploy: set UsoSvc to Manual explicitly (Server 2025 default = Automatic) - Setup cleanup: re-apply Set-Service Disabled on wuauserv/UsoSvc after DISM StartComponentCleanup (WaaSMedicSvc resets StartType during component store cleanup) - Deploy + Setup: add Administrator autologin (AutoAdminLogon, DefaultUserName, DefaultPassword, DefaultDomainName) in post-install.ps1; Assert-Step 5c validates it - Add Validate-DeployState.ps1: standalone host-side check of all Deploy-set state - Add Validate-SetupState.ps1: standalone host-side check of full post-Setup state - Mark §7.4, §7.1 and §7.2 e2e validation items as complete in TODO.md - Update docs: WINDOWS-TEMPLATE-SETUP.md (arch table, validation scripts section, autologin in confine Deploy/Setup); TEST-7.4-e2e.md checklist marked done Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

 ### 7.2 [P1] WU lifecycle — strategia B (Deploy: GPO + Manual; Setup: lifecycle)
 File: [template/Deploy-WinBuild2025.ps1](template/Deploy-WinBuild2025.ps1),
 [template/Setup-WinBuild2025.ps1](template/Setup-WinBuild2025.ps1).

-**Stato attuale (conflitto ordering)**:
- Deploy: `sc.exe config wuauserv start= disabled` + `sc.exe stop wuauserv` (idem UsoSvc, WaaSMedicSvc) + GPO `NoAutoUpdate=1`
- Setup Step 6: necessita servizi UP per SchTask SYSTEM run WU
- Setup Step 6b: re-disabilita servizi → doppio lavoro, fragile
+Strategia B: Deploy lascia servizi WU `start=demand` (Manual, default Windows) e scrive solo
+GPO `NoAutoUpdate=1` + `DisableWindowsUpdateAccess=1`. Setup Step 6 clears i GPO locks (Step A),
+avvia WU via SchTask SYSTEM, poi Step 6b disabilita servizi permanentemente post-update.

-**Strategia B — separazione pulita**:
-
-**Deploy** (post-install.ps1):
- Lascia servizi WU `start=demand` (Manual, default Windows) — NON `disabled`, NON `stop`
- Setta solo GPO `NoAutoUpdate=1`, `DisableWindowsUpdateAccess=1` → no background scheduled WU
- Risultato: WU è invocabile on-demand ma non parte mai da solo
-
-**Setup** (Step 6 / 6b):
- Step 6 (skip se `-SkipWindowsUpdate`): `sc.exe config wuauserv start= demand` (idempotent), avvia SchTask SYSTEM, attende exit code, parse 0/2/3/3010
- Step 6b (sempre, anche con `-Skip`): `sc.exe config wuauserv start= disabled` + `sc.exe stop wuauserv` (idem UsoSvc, WaaSMedicSvc), conferma GPO presenti — snapshot capture WU permanently off
-
-**Pattern run periodico patches** (allineato §2.5 snapshot versionato):
- Re-deploy template `BaseClean_<yyyyMMdd>` ogni N mesi via Deploy + Prepare (no `-Skip`) → patch applicate al template fresh
-
-**Validazione finale** (Setup Final gate):
- `wuauserv.StartType == Disabled`
- `UsoSvc.StartType == Disabled`
- GPO `NoAutoUpdate=1`, `DisableWindowsUpdateAccess=1`
-
-**Test acceptance**:
- Deploy stand-alone: `Get-Service wuauserv | Select StartType` → `Manual`, `Get-ItemProperty -Path 'HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name NoAutoUpdate` → 1
- Setup `-SkipWindowsUpdate`: Final gate vede `StartType=Disabled` (impostato da Step 6b)
- Setup senza `-Skip`: WU runs, exit 0/2/3, poi servizi disabled
+- [x] Deploy: rimuovere `sc.exe config wuauserv start= disabled` (e UsoSvc, WaaSMedicSvc)
+- [x] Deploy: aggiungere GPO `DisableWindowsUpdateAccess=1` (era mancante; `NoAutoUpdate=1` già presente)
+- [x] Setup Step 6 Step A: già rimuove `DisableWindowsUpdateAccess` + `NoAutoUpdate` prima del COM API — nessuna modifica necessaria
+- [x] Setup Step 6 Step D: già fa `Set-Service start=Manual` + `Start-Service` — idempotente con servizi già Manual
+- [x] Setup Step 6b: già disabilita wuauserv/UsoSvc + GPO keys — nessuna modifica necessaria
+- [x] E2e validation — completata §7.4 (2026-05-10)

- Run Prepare-WinBuild2025 dopo Deploy → tutti `Assert-Step` pass `[OK]` senza work

+**Fix emersi durante §7.4** (applicati):
+- Deploy: `UsoSvc` impostato a `Manual` esplicitamente (default Server 2025 = Automatic)
+- Setup cleanup: `Set-Service -StartupType Disabled` ri-applicato su wuauserv/UsoSvc dopo DISM `StartComponentCleanup` (DISM/WaaSMedicSvc può resettare StartType)
+- Deploy + Setup: autologin Administrator (`AutoAdminLogon=1`) aggiunto in post-install.ps1 e validato in Assert-Step 5c
+- Nuovi script: `template/Validate-DeployState.ps1`, `template/Validate-SetupState.ps1`

+
+```powershell
+.\Prepare-WinBuild2025.ps1 `
+    -VMIPAddress 192.168.79.xxx `
+    -SkipWindowsUpdate
+```
+
+**Cosa verificare nel log**:
+- Step 1 (Firewall): solo `[OK]` — nessun `Set-NetFirewallProfile`
+- Step 3 (WinRM): solo `[OK]` — nessun `Enable-PSRemoting` né `winrm set`
+- Step 4b (UAC): solo `[OK]` — nessun `Set-ItemProperty EnableLUA`
+- Step 5b (Explorer): solo `[OK]`
+- Step 5c (CIUX): solo `[OK]`
+- Step 4 (user `ci_build`): crea utente — operativo, non validation
+- Step 5 (CI dirs): crea `C:\CI\{build,output,scripts}` — operativo
+- Step 6: `[Setup] Skipping Windows Update` — corretto con `-SkipWindowsUpdate`
+- Step 6b: disabilita wuauserv/UsoSvc — deve girare sempre
+- Step 7-10: .NET, Python, VS Build Tools installati
+- Final gate: tutti e 7 i check `[OK]`
+- Exit code: `0`
+
+Se un Assert-Step fallisce con `[FAIL]` su Step 1/3/4b/5b/5c → Deploy non ha applicato
+quel setting → debug Deploy post-install.ps1 (controllare log nella VM).
+
+---
+
+## Step 4 — Prepare senza -Skip (WU lifecycle §7.2)
+
+> Solo se Step 3 è passato. La VM deve avere internet (VMnet8 NAT).
+
+```powershell
+.\Prepare-WinBuild2025.ps1 -VMIPAddress 192.168.79.xxx
+```
+
+**Atteso**:
+- Step 6 Step A: rimuove `DisableWindowsUpdateAccess` e `NoAutoUpdate` GPO keys
+- Step 6 Step D: avvia wuauserv/UsoSvc/bits/cryptsvc (già Manual → solo Start)
+- Step 6: WU gira via SchTask SYSTEM, ResultCode ∈ {0, 2, 3}
+- Step 6b: `wuauserv StartType=Disabled`, `UsoSvc StartType=Disabled`, GPO keys re-scritti
+- Final gate `Windows Update permanently disabled` → `[OK]`
+- Exit code: `0` (o `3010` se WU richiede reboot — ripetere con `-SkipWindowsUpdate`)
+
+---
+
+## Step 5 — Snapshot e promozione (opzionale)
+
+Se tutti i check di Step 3 e 4 passano:
+
+```powershell
+# Spegni VM test
+& 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' `
+    -T ws stop 'F:\CI\Templates\WinBuildTest\CI-WinBuild-test.vmx' soft

+    -T ws snapshot 'F:\CI\Templates\WinBuildTest\CI-WinBuild-test.vmx' `
+    "BaseClean_$(Get-Date -Format yyyyMMdd)"
+```
+
+Per promuovere a produzione (rimpiazza template esistente):
+1. Copia `F:\CI\Templates\WinBuildTest\` → `F:\CI\Templates\WinBuild\` (backup prima)
+2. Aggiorna `GITEA_CI_TEMPLATE_PATH` in `runner/config.yaml` se path cambia
+3. Aggiorna `GITEA_CI_SNAPSHOT_NAME` se usi nome versionato (vedi TODO §2.5)

 ### Razionale dell'ordine

- **Firewall first** — Windows blocca alcune chiamate WinRM finché non è classificato il
-  profilo di rete. Off subito → niente race condition durante Step 3.
- **Defender second** — disabilitato prima di WinRM e WU. WU scarica/installa update
-  senza scan (5-15 min risparmiati). Step 7-9 (download + install ~200-400 MB di
-  payload .NET/Python/VS) non vengono scansionati.
- **WinRM third** — già non interferito da firewall/defender. Hardening pulito.
- **User + UAC (4/4b)** — operazioni registro rapide; UAC off prima di dir/tool evita
-  prompt di elevazione; nessun motivo di aspettare WU.
+- **Steps 1-3 (validazioni)** — verificano prima le precondizioni Deploy (firewall off,
+  Defender off, WinRM pronto) in modo che i failure emergano subito, non a metà toolchain.
+- **User + UAC (4/4b)** — crea `ci_build`; valida UAC off (set da Deploy); UAC off prima
+  di dir/tool evita prompt di elevazione negli step 7-9.
 - **CI dirs prima di WU (Step 5)** — il worker WU scrive file temp in `C:\CI\`
  (`wu_worker.ps1`, `wu_result.txt`, ecc.); la directory deve esistere prima.
- **UI tweaks (5b/5c)** — tutti i tweak registro raggruppati prima del WU (lento);
-  scritture veloci, nessuna dipendenza da WU o toolchain.
- **WU sixth** — gira con tutto già off + `C:\CI` presente; condizioni ottimali.
- **WU disable subito dopo** — snapshot cattura WU permanentemente off.
+- **UI tweaks (5b/5c)** — validazioni registro rapide; raggruppate prima di WU (lento).
+- **WU (Step 6)** — clears i GPO lock di Deploy (Step A), avvia COM API via SYSTEM task,
+  poi Step 6b re-disabilita tutto → snapshot cattura WU permanentemente off.
 - **Toolchain (7-9) last** — WU completato, nessun scan su payload installer.

+      CI dirs (Step 5)   — C:\CI must exist before WU worker writes temp files there
+      UI tweaks (5b/5c)  — validates Deploy UX settings; fast assertions before slow WU

Simone	41611d46a7	fix(template): §7.4 Validate-SetupState -Remediate flag + Setup/Deploy tweaks	2026-05-10 14:26:35 +02:00
Simone	7d6ae42fcf	fix(template): §7.4 e2e fixes + autologin + validation scripts Fix emerged during §7.4 e2e test run (2026-05-10): - Deploy: set UsoSvc to Manual explicitly (Server 2025 default = Automatic) - Setup cleanup: re-apply Set-Service Disabled on wuauserv/UsoSvc after DISM StartComponentCleanup (WaaSMedicSvc resets StartType during component store cleanup) - Deploy + Setup: add Administrator autologin (AutoAdminLogon, DefaultUserName, DefaultPassword, DefaultDomainName) in post-install.ps1; Assert-Step 5c validates it - Add Validate-DeployState.ps1: standalone host-side check of all Deploy-set state - Add Validate-SetupState.ps1: standalone host-side check of full post-Setup state - Mark §7.4, §7.1 and §7.2 e2e validation items as complete in TODO.md - Update docs: WINDOWS-TEMPLATE-SETUP.md (arch table, validation scripts section, autologin in confine Deploy/Setup); TEST-7.4-e2e.md checklist marked done Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-10 11:30:11 +02:00
Simone	57e4a9713e	docs: add §7.4 e2e test runbook for Deploy↔Setup refactor validation Step-by-step guide to validate §7 refactor on a real VM: Deploy stand-alone, state verification, Prepare with/without -SkipWindowsUpdate, snapshot promotion. Includes expected values table and checklist. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-10 07:19:27 +02:00
Simone	ad39aa5cf4	docs(todo): §7 — replace emoji with [x]/[ ] checkboxes, reformat items Convert §7.1/7.2/7.3 from emoji ✅ + prose into standard [x] checkbox lists. §7.4 items converted to [ ] open checkboxes. Consistent with rest of TODO. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-10 07:11:03 +02:00
Simone	260e275b89	refactor(template): §7 — move OS hardening to Deploy, Setup becomes validation-only §7.1 — Setup Steps 1/3/4b/5b/5c converted to Assert-Step only: - Deploy post-install.ps1 now owns: Firewall (all profiles disabled), WinRM MaxMemory=2048MB/IdleTimeout=2h/MaxProcesses=25/StartupType=Automatic, lock screen (NoLockScreen), SM GPO policy key + scheduled task disable, DisableCAD in Winlogon, OOBE non-policy key. - Setup no longer re-applies these — validates them, throws if Deploy missed any. §7.2 — WU lifecycle Strategy B: - Deploy: replaces sc.exe disable with GPO locks only (NoAutoUpdate=1, DisableWindowsUpdateAccess=1); services remain Manual (Windows default). - Setup Step 6 Step A already clears these locks before COM API; Step 6b permanently disables services post-update. No Setup changes needed. §7.3 — Docs updated: - Deploy .DESCRIPTION reflects full hardening ownership. - Setup .DESCRIPTION marks validation-only steps, updates step ordering rationale. - WINDOWS-TEMPLATE-SETUP.md: three-script architecture table, CI-WinBuild.vmx path, Fase C step list + rationale + validation table updated. TODO: §7.1/7.2/7.3 marked done. §7.4 e2e pending (requires new VM snapshot). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-10 01:27:29 +02:00
