 ## PowerShell 5.1 — Vincoli critici
 Tutti gli script devono girare su **Windows PowerShell 5.1**. Le seguenti
 sintassi sono disponibili solo in PS 7+ e NON vanno usate:
 | Costrutto PS 7+           | Alternativa PS 5.1 corretta               |
 | ------------------------- | ----------------------------------------- |
 | `$x ??= 'default'`        | `if ($null -eq $x) { $x = 'default' }`    |
 | `$a ?? $b`                | `if ($null -ne $a) { $a } else { $b }`    |
 | `cmd1 && cmd2`            | `cmd1; if ($LASTEXITCODE -eq 0) { cmd2 }` |
 | `cmd1 \|\| cmd2`          | `cmd1; if ($LASTEXITCODE -ne 0) { cmd2 }` |
 | `$x is [int]`             | `$x -is [int]`                            |
 | Ternary `$a ? $b : $c`    | `if ($a) { $b } else { $c }`              |
 | `foreach-object` con `&&` | pipeline classico con `-ErrorAction Stop` |
 Ogni script deve avere in testa:
 ```powershell
 #Requires -Version 5.1
 Set-StrictMode -Version Latest
 $ErrorActionPreference = 'Stop'
 ```

 ---
 ## Transport layer
 - **Windows guest**: WinRM (`New-PSSession` con `New-CISessionOption` da `_Common.psm1`).
  Usare `Invoke-Command -Session`, `Copy-Item -ToSession / -FromSession`.
 - **Linux guest**: SSH/SCP via `ssh.exe` / `scp.exe`.
  Usare le funzioni di `scripts/_Transport.psm1`:
  `Invoke-SshCommand`, `Copy-SshItem`, `Test-SshReady`.
 - **vmrun.exe**: sempre invocato tramite `Invoke-Vmrun` da `_Common.psm1`
  (wrapper uniforme che gestisce `$LASTEXITCODE` e output).
 NON modificare il branch WinRM esistente quando si lavora sul branch Linux e viceversa.
 ---
 ## act_runner / Gitea Actions
 - Labels runner: `windows-build:host`, `linux-build:host`
 - Env vars iniettate in ogni job (da `runner/config.yaml`):
  - `GITEA_CI_TEMPLATE_PATH` — VMX Windows template
  - `GITEA_CI_LINUX_TEMPLATE_PATH` — VMX Linux template
  - `GITEA_CI_CLONE_BASE_DIR` — `F:\CI\BuildVMs`
  - `GITEA_CI_ARTIFACT_DIR` — `F:\CI\Artifacts`
  - `GITEA_CI_GUEST_CRED_TARGET` — `BuildVMGuest`
  - `GITEA_CI_SSH_KEY_PATH` — `F:\CI\keys\ci_linux`
 ---
 ## Regole di stile (PSScriptAnalyzer)
 Configurazione in `PSScriptAnalyzerSettings.psd1`. Regole principali:
 - Indentazione: **4 spazi** (no tab)
 - `Write-Host` e' permesso (output catturato da act_runner; `Write-Output` interferisce con i return value)
 - `Invoke-Expression` vietato
 - Funzioni state-changing devono supportare `-WhatIf` / `ShouldProcess`
 - Credenziali solo come `[PSCredential]`, mai plain-text string
 - Nessuna variabile globale (`$global:`)
 ---
 ## Errori frequenti da evitare
 1. **Sintassi PS 7+** in script PS 5.1 — vedi tabella sopra.
 2. **`$LASTEXITCODE` non controllato** dopo `vmrun`, `ssh`, `scp` — controllare sempre e fare `throw` se non zero.
 3. **Percorsi hardcoded senza parametro** — ogni path critico deve avere un parametro con default documentato.
 4. **Modificare entrambi i branch (WinRM e SSH) nello stesso script** — mantenerli separati con `if ($GuestOS -eq 'Linux')`.
 5. **Usare `New-PSSession` / WinRM verso host Linux** — Linux usa solo SSH tramite `_Transport.psm1`.
 6. **Non rimuovere il seed ISO dal VMX** dopo il primo boot Linux — `ide1:0.present = "FALSE"` deve essere settato dopo cloud-init.
 7. **`[ordered]@{}` non disponibile in PS 2** — non e' un problema qui (PS 5.1), ma ricordare che `[ordered]` e' PS 3+.
 8. **`ForEach-Object -Parallel`** — disponibile solo in PS 7+; usare `foreach` classico o `Start-Job`.
 9. **Snapshot template catturato con VM accesa** — produce file `*.vmem` / `*.vmsn` con memoria; `vmrun clone ... linked -snapshot=<name>` rifiuta con `Error: The virtual machine should not be powered on. It is already running.` anche se `vmrun list` mostra 0 VM. Catturare snapshot SOLO da stato fully powered-off (verificare assenza di `.vmem` nella dir template).
 10. **`vmrun getGuestIPAddress` per check "VM running"** — richiede VMware Tools attivi nel guest; in headless Tools puo' impiegare 30-60s a rispondere e il check appare bloccato. Usare `vmrun list` e cercare il path del VMX nell'output.

 [ValidatePattern($ipv4)]
 ```
 Estrarre la costante in un modulo condiviso `scripts/_Common.psm1` per evitare drift fra i 4 file (vedi §5.2).
 ### 1.5 [P1] PAT mai persistito quando si abilita `-UseGitClone`
 Requisiti di sicurezza per l'implementazione del clone in-VM. La sequenza operativa
 (quando, dove, come) è dettagliata nella sezione "In-VM Git Clone (Ottimizzazione) — riferimento §3.3".
 Vincoli da rispettare in qualsiasi implementazione di `-UseGitClone`:
 - [ ] PAT recuperato da Credential Manager **subito prima** della WinRM session, mai prima.
 - [ ] Iniettato via `$using:cred` o env var di sessione, mai in argv né in log/transcript.
 - [ ] Cancellato in `finally` interno alla scriptblock guest.
 - [ ] **Grep automatico post-job sui log**: se il PAT compare grezzo in `$jobLog` o
      `transcript.txt`, marcare la build come fallita e ruotare il PAT (regola di safety net,
      non sostituisce le precedenti).
 ### 1.6 [P2] Defender + Firewall + UAC tutti disattivati nel template — documentare il modello di minaccia
 File: [template/Deploy-WinBuild2025.ps1:485-551](template/Deploy-WinBuild2025.ps1) (UAC, ServerManager, DisableCAD, OOBE — set da Deploy), [template/Setup-WinBuild2025.ps1:176-336](template/Setup-WinBuild2025.ps1) (Firewall Step 1, Defender Step 2 validation-only post-refactor 2026-05-09, WinRM Step 3, User Step 4, UAC Step 4b, Dirs Step 5).
 Stato attuale (post-refactor §7):
 - **Defender**: disabled da Deploy (`DisableAntiSpyware=1` GPO + RTP off) — Setup Step 2 è validation-only
 - **Firewall**: disabled da Setup Step 1 (`Set-NetFirewallProfile ... -Enabled False`); §7.1 prevede spostamento a Deploy
 - **UAC**: `EnableLUA=0`, `LocalAccountTokenFilterPolicy=1` — duplicato Deploy + Setup Step 4b (§7.1 lo riduce a Assert-Step in Setup)
 Le scelte sono ragionevoli per un template lab efimero, ma vanno raccolte in un'unica sezione
 `BEST-PRACTICES.md §X — Threat Model & Hardening Trade-offs` che indichi:
 - Cosa è disattivato e perché (costo build vs. superficie d'attacco).
 - Quali condizioni rendono il modello inaccettabile (es. condivisione dell'host, esposizione
  VMnet8 a LAN aziendale, build di codice di terze parti non fidate).
 - Mitigazioni se uno di quei vincoli salta (Firewall On con regola WinRM esplicita,
  Defender con esclusione `C:\CI`, UAC On con `LocalAccountTokenFilterPolicy=1`).
 Senza questa nota, future modifiche possono accumulare ulteriori riduzioni di sicurezza
 senza tracciamento.
 ### 1.7 [P2] Rotazione password guest VM
 - [ ] Trimestrale. Aggiornare credenziale `BuildVMGuest` in Credential Manager + password
      effettiva nel template (richiede refresh snapshot — coordinare con §2.5).
 ### 1.8 [P2] Verifica Get-StoredCredential
 - [ ] Confermare che `Get-StoredCredential` funzioni correttamente in tutti gli script che
      lo usano (post-migrazione HTTPS).

 ## Deferred (Home Lab)
 Nel contesto di un home lab isolato, i seguenti security task hanno costi eccessivi
 relativi ai benefici in questo ambiente. **Rifiori se le condizioni cambiano**
 (code non fidata, sharing host, esposizione di rete, etc.).
 ### 1.2 [P1] [ ] Audit TrustedHosts setting
 File: [docs/BEST-PRACTICES.md:§2](docs/BEST-PRACTICES.md).
 Verificare che host Windows abbia `WSMan:\localhost\Client\TrustedHosts` configurato
 per `192.168.79.*` instead of `*`. Attualmente impostato a `*` durante setup template.
 **Stato attuale**: Accettabile per lab — WinRM è isolato su VMnet8 NAT.
 **Rifiori se**: Host esposto a LAN / internet.
 ### 1.3 [P0] [ ] Pinning hash SHA256 degli installer
 File: [template/Setup-WinBuild2025.ps1](template/Setup-WinBuild2025.ps1).
 SHA256 hash per dotnet-install.ps1, Python installer, vs_buildtools.exe.
 **Stato attuale**: Struttura aggiunta, valori placeholder — funziona con warning.
 **Rifiori quando**: Build di codice di terze parti non fidate che scaricano installer.
 ### 1.5 [P1] [ ] PAT mai persistito per `-UseGitClone`
 File: sezione "In-VM Git Clone (Ottimizzazione)" in TODO.
 Vincoli: PAT da Credential Manager subito prima sessione, non in argv/log,
 cancellato in finally, grep post-job se compare in transcript.
 **Stato attuale**: Struttura documentata, non implementata.
 **Rifiori quando**: `-UseGitClone` implementato (§3.3).
 ### 1.7 [P2] [ ] Rotazione password guest VM
 Aggiornare `BuildVMGuest` in Credential Manager + nel template ogni trimestre.
 **Stato attuale**: Password manuale.
 **Rifiori quando**: Change management/compliance lo richiede.
 ### 1.8 [P2] [ ] Verifica Get-StoredCredential
 Confermare che `Get-StoredCredential` (CredentialManager module) funzioni
 in tutti gli script che lo usano post-migrazione HTTPS.
 **Stato attuale**: Usato in template ma non testato in unit test.
 **Rifiori quando**: Script fallisce su recovery da Credential Manager.
 ### 3.4 [P3] [ ] Pre-warm pool di cloni
 File: `F:\CI\WarmPool\` (hypothetical); scheduled task via `scripts/Register-CIScheduledTasks.ps1`.
 Mantenere 2 cloni avviati in background, pronti per il binding a job. Salta la fase di
 `New-BuildVM + Wait-VMReady` (~30-60s) nel percorso critico. Richiede una VM "watcher" che
 monitora il pool e ricrea cloni dopo uso.
 **Stato attuale**: Disegnato ma non implementato. Dipende da §2.1 (IP allocator).
 **Rifiori quando**: Profiling mostra che New-BuildVM+Wait-VMReady è bottleneck >30% nel
 tempo totale di job. Con build >2 minuti, overhead stimato ~40% (rilevante solo per 1-min builds).
 ### 3.5 [P2] [ ] vCPU/RAM tuning per workload
 File: [docs/OPTIMIZATION.md](docs/OPTIMIZATION.md), VMX template config.
 Esporre parametri `-VMCpu` / `-VMMemory` a `Invoke-CIJob.ps1` per permettere override
 da workflow. Attualmente fisso a `numvcpus=4, memsize=6144` — subottimo per build leggeri
 (waste) e pesanti (throttle).
 **Stato attuale**: Progettato, non implementato. Template supporta la modifica.
 **Rifiori quando**: Performance profiling mostra contentione CPU/RAM è bottleneck per la
 workload target. Per home lab, 4 vCPU/6 GB è ragionevole compromesso.

 ## 2.1. Threat Model — Disabled Security Features
 ### Current state: Defender, Firewall, and UAC disabled
 The template VM disables Windows Defender, Windows Firewall, and User Account Control (UAC).
 This is **intentional** — not a bug, not an oversight. Each has tradeoffs:
 | Feature | Disabled? | Why | Cost if enabled |
 |---------|-----------|-----|-----------------|
 | **Windows Defender** | Yes | Real-time AV scanning blocks .NET compilation, Python wheels, and npm installs | 5–10 min per build overhead; false positives on dev tools |
 | **Windows Firewall** | Yes | Blocks inbound WinRM even with rules; requires Domain/Home profile tuning | Complex rules; fragile across OS updates |
 | **UAC (LocalAccountTokenFilterPolicy)** | Yes | Prevents non-elevated WinRM scripts from running builds | Requires built-in Administrator account; WinRM behaves like a user with limited rights |
 ### When this threat model is acceptable
 Current threat model is **safe** if **ALL** of these are true:
 1. **Isolated lab environment** — Build VMs exist only on VMnet8 (NAT), not on host LAN.
 2. **No shared resources** — Host is not shared with untrusted users or concurrent CI systems.
 3. **Trusted source code** — Code being built is from trusted repositories (internal team only).
 4. **No external access** — VMnet8 is not bridged or exposed to corporate LAN or internet.
 5. **Act_runner is trusted** — The act_runner service token cannot be used to access host resources outside the isolated network.
 If all conditions hold, the attack surface is limited to:
 - Network eavesdropping on 192.168.79.0/24 (mitigated: WinRM is HTTPS)
 - Code injection via malicious commits (mitigated: code review process)
 - Privilege escalation from VM to host (mitigated: VMs are ephemeral; no persistence)
 ### When the model breaks down
 **Do NOT use this configuration if:**
 - ❌ **Third-party code builds** — Running untrusted vendor code (open-source projects, third-party libraries with build scripts)
 - ❌ **Shared build machine** — Other teams or processes share the host CPU/storage
 - ❌ **LAN-exposed network** — VMnet8 is bridged to corporate LAN or internet
 - ❌ **Host resource sharing** — Build VMs can access host shares, USB drives, or external storage
 - ❌ **Long-lived VMs** — VMs are not destroyed after each build (antivirus blind spot for persistence)
 In these scenarios, disabled AV and firewall create **unacceptable risk**.
 ### Mitigations if constraints change
 If you must run in a less-isolated environment, re-enable protections **with cost awareness**:
 #### Option 1: Re-enable Firewall only (lowest cost)
 ```powershell
 # In template VM via WinRM, before taking BaseClean snapshot:
 Set-NetFirewallProfile -Profile Domain, Public, Private -Enabled $true
 # Add inbound rule for WinRM listener
 New-NetFirewallRule -Name "WinRM-HTTPS" `
    -DisplayName "Windows Remote Management (HTTPS)" `
    -Direction Inbound `
    -LocalPort 5986 `
    -Protocol TCP `
    -Action Allow
 ```
 **Cost:** 30–60 seconds per build (firewall rule evaluation + logging).  
 **Benefit:** Blocks outbound malware callbacks if VM is compromised.
 #### Option 2: Re-enable Defender with exclusions (moderate cost)
 ```powershell
 # In template VM, enable Defender but exclude build directories:
 Enable-MpComputerDefault   # Re-enable Defender
 Add-MpPreference -ExclusionPath @(
    'C:\Build',
    'C:\Users\ci_build\AppData\Local\Microsoft\dotnet',
    'C:\Users\ci_build\AppData\Roaming\npm'
 ) -Force
 # Reduce scanning aggressiveness:
 Set-MpPreference -DisableRealtimeMonitoring $false -DisableBehaviorMonitoring $true
 ```
 **Cost:** 2–5 min per build (initial scan; exclusions help but don't eliminate overhead).  
 **Benefit:** Detects known malware uploaded in build artifacts.
 #### Option 3: Enable UAC for elevated builds only (requires refactor)
 ```powershell
 # NOT RECOMMENDED without major refactoring.
 # WinRM remote commands run as non-elevated user; builds fail.
 # Requires either:
 #   - Running WinRM as built-in Administrator (security anti-pattern)
 #   - Adding explicit runas prompts (breaks automation)
 #   - Using Windows Task Scheduler instead of WinRM (complexity)
 ```
 ### Audit and sign-off
 Before deploying to production or a shared host:
 1. **Document the decision:** Update this section with current date and approver name.
 2. **Test the mitigations:** Create test clone, enable firewall/AV, measure build time overhead.
 3. **Establish monitoring:** Run Watch-RunnerHealth.ps1 continuously; alert on service restarts.
 4. **Plan rotation:** Schedule quarterly credential rotation (see §1 Credential Management).

 | ------------------------ | ------------------------------------------------------------------ | -------------------------------------------- |
 | **Ubuntu 24.04 LTS**     | Toolchain recente, supporto LTS fino al 2029, cloud-init ottimo    | Snap default (lento per CI)                  |
 | Debian 12                | Stabile, leggero, no snap                                          | Toolchain meno recente                       |

 **Scelta proposta**: Ubuntu 24.04 LTS minimal. Rationale: maggior parità con runner GitHub
 ufficiali (`ubuntu-latest` mappa a 22.04/24.04), toolchain recente out-of-box, cloud-init
 maturo per provisioning automatico.
 ### Transport host → VM
 | Opzione                  | Pro                                                                | Contro                                       |
 | ------------------------ | ------------------------------------------------------------------ | -------------------------------------------- |
 | **SSH (chiave pubblica)**| Standard Linux, supporto nativo OpenSSH su Win11/Server 2025       | Diversa API rispetto WinRM (PSSession)       |
 | WinRM su Linux (PSCore)  | Codice script unificato                                            | Setup complesso, non standard, fragile       |
 **Scelta proposta**: SSH key-based con `ssh.exe` + `scp.exe` (built-in Windows 10+) o
 modulo `Posh-SSH`. WinRM su Linux non è production-ready.
 ### Layer di astrazione
 Aggiungere `scripts/_Transport.psm1` con interfaccia comune:
 ```powershell
 # Pseudo-API
 function Invoke-RemoteCommand {
    param($Target, $ScriptBlock, $Args, [ValidateSet('WinRM','SSH')] $Transport)
 }
 function Copy-RemoteItem {
    param($Source, $Destination, $Target, $Direction, $Transport)
 }
 function Test-RemoteReady {
    param($Target, $TimeoutSec, $Transport)
 }
 ```
 Implementazioni:
 - **WinRM** wrapper: `New-PSSession` + `Invoke-Command` + `Copy-Item -ToSession`
 - **SSH** wrapper: `ssh.exe` + `scp.exe` con `-i $keyfile -o StrictHostKeyChecking=accept-new`
 `Invoke-CIJob.ps1` riceve `-GuestOS Windows|Linux` (o auto-detect dal VMX `guestOS`),
 sceglie transport.

 Differenza chiave da Windows: l'immagine di partenza e gia installata (cloud VMDK,
 ~600 MB). Nessuna fase di installazione OS  cloud-init provvede al bootstrap al primo
 boot in 30-60 secondi. La NIC non richiede lo swap e1000e  vmxnet3 perche il kernel
 Linux ha il driver vmxnet3 nativo.

-## TODO — Implementazione
+## Prerequisiti host
-### Pre-requisiti host
+- [x] **SSH key CI dedicata**  generare una volta sola (no passphrase):
 - [ ] **OpenSSH client** verificato presente su host (default Win11/Server 2025)
      ```powershell
      Get-WindowsCapability -Online -Name OpenSSH.Client*
      ```
 - [ ] **Genera SSH key dedicata** per CI (no passphrase, separata da chiavi utente):
  ```powershell
  New-Item -ItemType Directory -Force F:\CI\keys | Out-Null
  ssh-keygen -t ed25519 -f F:\CI\keys\ci_linux -N '""' -C 'ci-linux-runner'
  # Risultato: F:\CI\keys\ci_linux (privata) + F:\CI\keys\ci_linux.pub (pubblica)
  ```
- [ ] **Aggiungere a `Setup-Host.ps1`** uno step opzionale `-GenerateLinuxCIKey` che crea
+- [x] **OpenSSH client** verificato presente sull'host (default su Windows 11):
-      la chiave e la archivia con permessi corretti (`F:\CI\keys\` con ACL ristretta)
+  ```powershell
-
+  Get-WindowsCapability -Online -Name OpenSSH.Client* | Select-Object State
-### Fase A — Crea VM e installa Ubuntu
+  # Atteso: State = Installed
 - [ ] Crea nuova VM in VMware Workstation (4 vCPU, 4 GB RAM, 40 GB thin)
 - [ ] NIC: VMnet8 (NAT)
 - [ ] Boot da ISO Ubuntu Server 24.04 LTS minimal
 - [ ] Durante install scegli:
  - [ ] **Minimal install** (no extra packages)
  - [ ] OpenSSH server: **Yes**
  - [ ] Username: `ci_build`
  - [ ] Hostname: `ci-linux-template`
  - [ ] LVM: opzionale (non necessario per template)
 - [ ] Annota IP DHCP (`ip a`)
 ### Fase B — Provisioning iniziale (manuale, una volta)
 Dentro la VM, come `ci_build`:
 - [ ] **Disabilita swap permanente** (overhead I/O su NVMe condivisa):
  ```bash
  sudo swapoff -a
  sudo sed -i '/ swap / s/^/#/' /etc/fstab
  ```
 - [x] **`F:\CI\Templates\LinuxBuild2404\`** creata (Setup-Host.ps1 o manuale)
 - [x] **`F:\CI\ISO\`** creata (il VMDK viene scaricato automaticamente da Deploy se mancante)
- [ ] **Disabilita servizi non necessari** (snap, motd-news, ecc.):
+---
  ```bash
  sudo systemctl disable --now snapd.service snapd.socket snapd.seeded.service 2>/dev/null
  sudo systemctl disable --now motd-news.timer 2>/dev/null
  sudo systemctl disable --now apt-daily.timer apt-daily-upgrade.timer
  ```
  Rationale: snap e timer apt rallentano boot e mangiano CPU su VM efimere.
- [ ] **Sudo passwordless** per `ci_build` (parità con WinRM admin senza prompt UAC):
+## Fase A  Deploy-LinuxBuild2404.ps1
  ```bash
  echo 'ci_build ALL=(ALL) NOPASSWD:ALL' | sudo tee /etc/sudoers.d/90-ci_build
  sudo chmod 440 /etc/sudoers.d/90-ci_build
  ```
- [ ] **Authorized SSH key** dell'host CI:
+Script host-side. Produce una VM pronta con cloud-init completato e SSH raggiungibile.
-  ```bash
+Non richiede installazione OS  parte dal cloud VMDK pre-built.
  mkdir -p ~/.ssh && chmod 700 ~/.ssh
  # Incolla la chiave pubblica generata su host (F:\CI\keys\ci_linux.pub)
  echo 'ssh-ed25519 AAAA... ci-linux-runner' >> ~/.ssh/authorized_keys
  chmod 600 ~/.ssh/authorized_keys
  ```
- [ ] **SSH hardening** per template (ma non così stretto da bloccare CI):
+- [x] **Step 1  Validate prerequisites**
-  ```bash
+  - Parametro `-VMwareWorkstationDir` (default `C:\Program Files (x86)\VMware\VMware Workstation`) — stesso pattern di Deploy-WinBuild2025.ps1
-  sudo sed -i 's/^#*PermitRootLogin.*/PermitRootLogin no/' /etc/ssh/sshd_config
+  - `vmrun.exe` presente in `$VMwareWorkstationDir`
-  sudo sed -i 's/^#*PasswordAuthentication.*/PasswordAuthentication no/' /etc/ssh/sshd_config
+  - `vmware-vdiskmanager.exe` presente in `$VMwareWorkstationDir`
-  sudo systemctl restart sshd
+    (`$vdiskMgr = Join-Path $VMwareWorkstationDir 'vmware-vdiskmanager.exe'`)
-  ```
+  - SSH key `F:\CI\keys\ci_linux.pub` presente
  - Cartella destinazione VMX non gia occupata (o `-Force` per sovrascrivere)
  - (il VMDK sorgente viene gestito in Step 1b — nessun prerequisito manuale)
-### Fase C — Setup-LinuxTemplateVM.sh (script equivalente a Setup-WinBuild2025.ps1)
+- [x] **Step 1b  Download cloud VMDK se assente** (`F:\CI\ISO\` come cache locale)
-
+  ```powershell
-Da creare: `template/Setup-LinuxTemplateVM.sh` con `set -euo pipefail` + `assert_step()` helper.
+  $VmdkUrl  = 'https://cloud-images.ubuntu.com/noble/current/noble-server-cloudimg-amd64.vmdk'
-
+  $VmdkPath = 'F:\CI\ISO\noble-server-cloudimg-amd64.vmdk'
- [ ] **Helper `assert_step`** (throw on fail, log su success):
+  if (-not (Test-Path $VmdkPath)) {
-  ```bash
+      Write-Host "[Deploy] VMDK non trovato, avvio download..."
-  assert_step() {
+      New-Item -ItemType Directory -Force F:\CI\ISO | Out-Null
-      local step="$1"; local desc="$2"; shift 2
+      $tmp = "$VmdkPath.part"
-      if "$@" >/dev/null 2>&1; then
+      try {
-          echo "  [OK] [$step] $desc"
+          Invoke-WebRequest -Uri $VmdkUrl -OutFile $tmp -UseBasicParsing
-      else
+          Move-Item $tmp $VmdkPath
-          echo "  [FAIL] [$step] $desc" >&2; exit 1
+          Write-Host "[Deploy] Download completato: $VmdkPath"
-      fi
+      } catch {
          Remove-Item $tmp -ErrorAction SilentlyContinue
          throw "[Deploy] Download VMDK fallito: $_"
      }
  } else {
      Write-Host "[Deploy] VMDK trovato in cache: $VmdkPath"
  }
  ```
  - Usa `Invoke-WebRequest` (nativo PowerShell, no dipendenze esterne)
  - Scrittura atomica: file `.part` durante download, rinomina solo a completamento
  - In caso di errore: il file `.part` viene rimosso, l'eccezione termina lo script
  - Parametro opzionale `-VmdkUrl` per sovrascrivere l'URL (es. mirror locale)
- [ ] **Step 1 — `apt update` + upgrade**
+- [x] **Step 2  Genera cloud-init user-data + meta-data** (inline, no template esterno)
  - `meta-data`: `instance-id: linuxbuild-001`, `local-hostname: ci-linux-template`
  - `user-data` (YAML):
    - `hostname: ci-linux-template`
    - `users`: utente `ci_build`, shell `/bin/bash`, `sudo: ALL=(ALL) NOPASSWD:ALL`,
      `ssh_authorized_keys` con contenuto di `ci_linux.pub`
    - Nessun `packages`, nessun `package_update`, nessun `runcmd`:
      tutto il provisioning (apt, toolchain, SSH hardening, swap) e' delegato a
      `Prepare-LinuxBuild2404.ps1` via `Setup-LinuxBuild2404.sh`
    - Nessun `power_state`: il reboot non e' necessario, cloud-init completa tutto al primo boot
 - [x] **Step 3  Costruisce seed ISO nocloud** via IMAPI2FS COM
  - Due file: `user-data` + `meta-data` (volume label: `cidata`)
  - Stesso codice COM gia usato in Deploy-WinBuild2025.ps1 Step 3
  - Output: `F:\CI\Templates\LinuxBuild2404\cloud-init-seed.iso`
 - [x] **Step 4  Converti e ridimensiona cloud VMDK**
  - Il cloud VMDK e' in formato **streamOptimized** (distribuzione), non direttamente resizeable.
  - Converti a **monolithicSparse** (tipo 0) contestualmente alla copia:
    `& $vdiskMgr -r noble-server-cloudimg-amd64.vmdk -t 0 LinuxBuild2404.vmdk`
  - Ridimensiona a 40 GB: `& $vdiskMgr -x 40GB LinuxBuild2404.vmdk`
    (stessa variabile `$vdiskMgr` di Deploy-WinBuild2025.ps1, valorizzata in Step 1)
  - Il resize avviene PRIMA del primo boot: l'immagine Ubuntu 24.04 ha i moduli
    cloud-init `growpart` + `resizefs` abilitati di default — espandono automaticamente
    la partizione root e il filesystem durante il primo avvio, senza `runcmd` aggiuntivi
 - [x] **Step 5  Genera .vmx**
  - `guestOS = "ubuntu-64"`, `firmware = "efi"`
    (Ubuntu 24.04 cloud image usa GPT con partizione EFI; il boot sotto BIOS legacy fallirebbe)
  - NIC: `vmxnet3`, VMnet8
  - Disco: `LinuxBuild2404.vmdk` (scsi0:0)
  - CD-ROM secondario: `cloud-init-seed.iso` (connesso)
  - Nessun USB controller, nessuna sound card
  - `memsize = 4096`, `numvcpus = 4`
 - [x] **Step 6  Power on** (`vmrun start nogui`)
 - [x] **Step 7  Polling SSH port 22** fino a ready
  - `Test-NetConnection -ComputerName $IP -Port 22` ogni 10 secondi
  - Timeout: 5 minuti (cloud-init + reboot finale)
  - IP rilevato via `vmrun getGuestIPAddress`
  > open-vm-tools e pre-installato nell'Ubuntu 24.04 cloud image.
  > `vmrun getGuestIPAddress` funziona senza installazione aggiuntiva.
 - [x] **Step 8  Verifica cloud-init completato**
  ```powershell
  ssh -i F:\CI\keys\ci_linux -o StrictHostKeyChecking=accept-new `
      -o ConnectTimeout=5 ci_build@$IP `
      "test -f /var/lib/cloud/instance/boot-finished && echo OK"
  # Atteso: OK
  ```
 - [x] **Step 9  Rimuove seed ISO dal VMX**
  - Setta `ide1:0.present = "FALSE"` nel VMX
  - Evita che linked clone ricevano il seed ISO e ri-eseguano cloud-init
 - [x] **Step 10  Print summary** (VMX path, IP, SSH fingerprint)
 ---
 ## Fase B  Prepare-LinuxBuild2404.ps1
 Script host-side. Copia il setup script, lo esegue via SSH, valida stato, prende snapshot.
 Equivalente di `Prepare-WinBuild2025.ps1` con SSH al posto di WinRM.
 - [x] **Step 1  Pre-flight**
  - VMX presente; se VM spenta, avvia con `vmrun start nogui`
  - SSH key `F:\CI\keys\ci_linux` presente
  - `ssh.exe` e `scp.exe` nel PATH host
  - TCP/22 raggiungibile (`Test-NetConnection`)
 - [x] **Step 2  Auto-detect IP** via `vmrun getGuestIPAddress $VMXPath`
  - Se `-VMIPAddress` e fornito esplicitamente, salta il rilevamento automatico
 - [x] **Step 3  Aggiungi host key a known_hosts**
  ```powershell
  ssh -i F:\CI\keys\ci_linux -o StrictHostKeyChecking=accept-new `
      ci_build@$IP "echo connected" | Out-Null
  ```
  Solo al primo run; idempotente se gia presente.
 - [x] **Step 4  Copia Setup-LinuxBuild2404.sh in VM**
  ```powershell
  scp -i F:\CI\keys\ci_linux `
      "$PSScriptRoot\Setup-LinuxBuild2404.sh" `
      "ci_build@${IP}:/tmp/Setup-LinuxBuild2404.sh"
  ```
  Valida: confronta size locale vs remota via `ssh ... stat -c %s /tmp/...`
 - [x] **Step 5  Esegui setup script** nel guest
  ```powershell
  ssh -i F:\CI\keys\ci_linux ci_build@$IP `
      "chmod +x /tmp/Setup-LinuxBuild2404.sh && sudo /tmp/Setup-LinuxBuild2404.sh"
  # Cattura exit code; != 0 => abort con errore leggibile
  ```
  Flag opzionali passabili: `--skip-update`, `--dotnet`, `--mingw`
 - [x] **Step 6  Post-setup remote validation** (batch via singola sessione SSH)
  - `systemctl is-active ssh` = `active`
  - `id ci_build` contiene `sudo`
  - `sudo -n true` exit 0 (passwordless sudo)
  - `which gcc g++ clang cmake python3 git 7z` tutti trovati
  - `test -d /opt/ci/build -a -d /opt/ci/output -a -d /opt/ci/scripts` exit 0
  - `swapon --show` output vuoto (swap disabilitato)
  - `grep -q "^PasswordAuthentication no" /etc/ssh/sshd_config`
 - [x] **Step 7  Shutdown VM**
  ```powershell
  & $vmrun stop $VMXPath soft
  # Polling vmrun list fino a VM non piu presente
  ```
 - [x] **Step 8  Snapshot BaseClean-Linux**
  ```powershell
  & $vmrun snapshot $VMXPath 'BaseClean-Linux'
  ```
 - [x] **Final  Print summary** (VMX, snapshot name, toolchain versions rilevate)
 ---
 ## Fase C  Setup-LinuxBuild2404.sh
 Script guest-side (Bash). Installazione toolchain CI e hardening.
 Eseguito da Prepare via SSH come `ci_build` con sudo.
 Header: `#!/usr/bin/env bash` + `set -euo pipefail`
 Helper `assert_step()`: stampa `[OK] [Step N] desc` su successo, `exit 1` su fallimento.
 - [x] **Step 1  apt update + upgrade** (saltabile con `--skip-update`)
  ```bash
  sudo DEBIAN_FRONTEND=noninteractive apt-get update -qq
  sudo DEBIAN_FRONTEND=noninteractive apt-get upgrade -y -qq
  assert_step 'apt' 'no errors' true
  ```
- [ ] **Step 2 — Toolchain build essentials**
+- [x] **Step 2  Toolchain build essentials**
  ```bash
  sudo apt-get install -y -qq \
      build-essential gcc g++ clang \
      make cmake ninja-build \
-      pkg-config autoconf automake libtool \
+      pkg-config autoconf automake libtool
      git curl wget ca-certificates \
      python3 python3-pip python3-venv \

  assert_step 'toolchain' 'gcc presente'   command -v gcc
  assert_step 'toolchain' 'clang presente' command -v clang
  assert_step 'toolchain' 'cmake presente' command -v cmake
  assert_step 'toolchain' 'python3 presente' command -v python3
  ```
  - assert: `command -v gcc`, `command -v clang`, `command -v cmake`
- [ ] **Step 3 — Toolchain extra opzionale**
+- [x] **Step 3  Python**
-  - [ ] **mingw-w64** se serve cross-compile per Windows: `sudo apt-get install -y mingw-w64`
+  ```bash
-  - [ ] **.NET SDK** (per parità Windows): script `dotnet-install.sh` con channel pinned
+  sudo apt-get install -y -qq python3 python3-pip python3-venv
-  - [ ] **Node.js** se workflow lo richiede: nvm o nodesource repo
+  sudo ln -sf /usr/bin/python3 /usr/local/bin/python
  ```
  - assert: `python3 --version`, `pip3 --version`
- [ ] **Step 4 — CI working directories**
+- [x] **Step 4  Tier-1 Toolchain** (speculare a §6.6 Windows: Git + 7-Zip)
  ```bash
  sudo apt-get install -y -qq git p7zip-full curl wget ca-certificates
  ```
  - assert: `command -v git`, `command -v 7z`
 - [x] **Step 4b  .NET SDK** (opzionale, flag `--dotnet`)
  ```bash
  curl -fsSL https://dotnet.microsoft.com/download/dotnet/scripts/v1/dotnet-install.sh \
      | sudo bash -s -- --channel 10.0 --install-dir /usr/local/dotnet
  sudo ln -sf /usr/local/dotnet/dotnet /usr/local/bin/dotnet
  ```
  - assert: `dotnet --version`
 - [x] **Step 4c  mingw-w64** (opzionale, flag `--mingw`  cross-compile per Windows)
  ```bash
  sudo apt-get install -y -qq mingw-w64
  ```
  - assert: `command -v x86_64-w64-mingw32-gcc`
 - [x] **Step 5  CI directories**
  ```bash
  sudo mkdir -p /opt/ci/{build,output,scripts,cache}
  sudo chown -R ci_build:ci_build /opt/ci
  assert_step 'dirs' 'tutte presenti' test -d /opt/ci/build -a -d /opt/ci/output
  ```
  - assert: `test -d /opt/ci/build`, `test -d /opt/ci/output`, `test -d /opt/ci/scripts`
- [ ] **Step 5 — Disabilita auto-update apt** (no surprise reboot/lock):
+- [x] **Step 6  SSH hardening** (PasswordAuth off  gia impostato da cloud-init, ri-validato)
  ```bash
-  sudo apt-get remove -y unattended-upgrades 2>/dev/null
+  sudo sed -i 's/^#*PasswordAuthentication.*/PasswordAuthentication no/' /etc/ssh/sshd_config
-  sudo systemctl mask apt-daily.service apt-daily-upgrade.service
+  sudo sed -i 's/^#*PubkeyAuthentication.*/PubkeyAuthentication yes/' /etc/ssh/sshd_config
  sudo systemctl restart sshd
  ```
  - assert: `grep -q "^PasswordAuthentication no" /etc/ssh/sshd_config`
 - [x] **Step 7  Disabilita swap permanente**
  ```bash
  sudo swapoff -a
  sudo sed -i '/ swap / s/^/#/' /etc/fstab
  ```
  - assert: `swapon --show` output vuoto
 - [x] **Step 8  Disabilita apt auto-update** (no lock durante build)
  ```bash
  sudo systemctl mask apt-daily.service apt-daily-upgrade.service \
      apt-daily.timer apt-daily-upgrade.timer
  sudo apt-get remove -y unattended-upgrades 2>/dev/null || true
  ```
- [ ] **Step 6 — Cleanup pre-snapshot**
+- [x] **Step 9  Cleanup pre-snapshot**
  ```bash
  sudo apt-get clean
  sudo rm -rf /var/lib/apt/lists/*
  sudo journalctl --vacuum-time=1d
  sudo rm -rf /tmp/* /var/tmp/*
-  history -c && cat /dev/null > ~/.bash_history
+  history -c
-  # Zero free space (riduce dim VMDK dopo compact, opzionale)
+  cat /dev/null > ~/.bash_history
  # sudo dd if=/dev/zero of=/zero bs=1M; sudo rm /zero
  ```
- [ ] **Step 7 — Final pre-snapshot validation**
+- [x] **Final  Gate pre-snapshot** (exit 1 se qualcosa manca)
-  - SSH server abilitato e in ascolto su 22
+  - Ogni tool richiesto raggiungibile con `command -v`
-  - `sudo` passwordless funzionante per `ci_build`
+  - `/opt/ci/{build,output,scripts}` esistenti con owner `ci_build`
-  - Tutti i tool elencati (`gcc --version`, `cmake --version`, ecc.) ritornano exit 0
+  - `swapon --show` vuoto
-  - `/opt/ci/{build,output,scripts}` esistono con owner corretto
+  - `sshd` attivo
-  - No leftover `/tmp/*`, history vuota
+  - `PasswordAuthentication no` in sshd_config
-
+  - Root filesystem >= 38 GB (verifica che cloud-init `growpart` abbia funzionato):
 ### Fase D — Prepare-LinuxTemplateSetup.ps1 (orchestratore host-side)
 Equivalente di `Prepare-WinBuild2025.ps1` per Linux. Usa SSH invece di WinRM.
 - [ ] **Pre-flight host**:
  - SSH key esiste (`F:\CI\keys\ci_linux`)
  - `ssh.exe` e `scp.exe` raggiungibili
  - IP target risponde a `Test-NetConnection -Port 22`
 - [ ] **Copia script in VM**:
  ```powershell
  scp -i F:\CI\keys\ci_linux -o StrictHostKeyChecking=accept-new `
      template\Setup-LinuxTemplateVM.sh ci_build@${VMIPAddress}:/tmp/
  ```
 - [ ] **Esegui script in VM**:
  ```powershell
  ssh -i F:\CI\keys\ci_linux ci_build@${VMIPAddress} `
      "chmod +x /tmp/Setup-LinuxTemplateVM.sh && sudo /tmp/Setup-LinuxTemplateVM.sh"
  ```
  Cattura stdout + exit code, parse `[OK]`/`[FAIL]` lines.
 - [ ] **Post-setup remote validation** (parità Windows): query SSH per state checks:
  - `systemctl is-active ssh` = active
  - `id ci_build` ritorna gruppo + sudo
  - `gcc --version`, `cmake --version`, `python3 --version` exit 0
  - `test -d /opt/ci/build` exit 0
 ### Fase E — Snapshot
 - [ ] Solo se Prepare exit 0 → power off VM:
    ```bash
-  sudo shutdown -h now
+    df -BG / | awk 'NR==2{gsub("G","",$2); if ($2+0 < 38) {print "FAIL: root fs too small"; exit 1}}'
    ```
- [ ] Take snapshot in VMware Workstation: **`BaseClean-Linux`** (case-sensitive)
+  - Nessun installer residuo in `/tmp`
-### Fase F — Adattamento script CI
+---
- [ ] **`scripts/_Transport.psm1`** (nuovo modulo) con interfaccia comune
+## Fase D  Adattamento script CI
 - [ ] **`scripts/Invoke-CIJob.ps1`** — aggiungere `-GuestOS Windows|Linux`, branching su transport
 - [ ] **`scripts/Wait-VMReady.ps1`** — supporto SSH probe (`Test-NetConnection -Port 22` + `ssh -o ConnectTimeout=5 ...`)
 - [ ] **`scripts/Invoke-RemoteBuild.ps1`** — branch SSH+scp per Linux
 - [ ] **`scripts/Get-BuildArtifacts.ps1`** — `scp` per Linux invece di `Copy-Item -FromSession`
 - [ ] **`scripts/New-BuildVM.ps1`** — already OS-agnostic (vmrun clone), verificare che `BaseClean-Linux` sia parametrizzabile
 - [ ] **`scripts/Remove-BuildVM.ps1`** — already OS-agnostic
-### Fase G — Workflow Gitea
+- [x] **`scripts/_Transport.psm1`**  nuovo modulo SSH-only per il branch Linux.
  Gli script Windows esistenti NON vengono modificati ora; il refactoring WinRM e' rinviato.
  ```powershell
  function Invoke-SshCommand { param($IP, $User, $KeyPath, $Command, ...) }
  function Copy-SshItem      { param($Source, $Dest, $IP, $User, $KeyPath, [ValidateSet('ToGuest','FromGuest')] $Direction, ...) }
  function Test-SshReady     { param($IP, $User, $KeyPath, $TimeoutSec, ...) }
  ```
  Gli script CI (`Invoke-CIJob`, `Invoke-RemoteBuild`, `Get-BuildArtifacts`) chiameranno
  queste funzioni nel branch Linux senza toccare il branch WinRM esistente.
- [ ] **Registrare label `linux-build`** sul runner (oppure secondo runner dedicato):
+- [x] **`scripts/Invoke-CIJob.ps1`**  aggiungere parametro `-GuestOS Windows|Linux`
  - Auto-detect da VMX `guestOS` field se non fornito
  - Branch su transport (WinRM vs SSH) in ogni fase
 - [x] **`scripts/Wait-VMReady.ps1`**  aggiungere `-Transport SSH`
  - Probe: `Test-NetConnection -Port 22` + `ssh -o ConnectTimeout=5 ... "echo ok"`
 - [x] **`scripts/Invoke-RemoteBuild.ps1`**  branch SSH+scp per Linux
  - Transfer: `scp` invece di `Copy-Item -ToSession`
  - Build: `ssh ... "cd /opt/ci/build && $BuildCommand"`
 - [x] **`scripts/Get-BuildArtifacts.ps1`**  branch `scp` per Linux
  - `scp -r ci_build@$IP:/opt/ci/output/* $LocalArtifactDir\`
 - [ ] **`scripts/New-BuildVM.ps1`**  gia OS-agnostic (vmrun clone)
  - Verificare che `-SnapshotName BaseClean-Linux` funzioni correttamente
 - [ ] **`scripts/Remove-BuildVM.ps1`**  gia OS-agnostic, nessuna modifica prevista
 ---
 ## Fase E  Runner e workflow Gitea
 - [x] **Label `linux-build`** aggiunta al runner in `runner/config.yaml`:
  ```yaml
  # runner/config.yaml — aggiungere a labels esistenti
  labels:
    - 'windows-build:host'
    - 'linux-build:host'
  ```
- [ ] **Workflow matrix**:
+- [x] **Variabile d'ambiente** `GITEA_CI_LINUX_TEMPLATE_PATH` nel servizio act_runner:
  `F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx`
 - [x] **Workflow matrix** di esempio (`gitea/workflow-example.yml` aggiornato):
  ```yaml
  jobs:
    build:
  strategy:
    matrix:
      target: [windows, linux]
  runs-on: ${{ matrix.target }}-build
      steps:
        - uses: actions/checkout@v4
        - run: pwsh -File scripts/Invoke-CIJob.ps1 -GuestOS ${{ matrix.target }}
  ```
 ### Fase H — Test e2e
 - [ ] **Smoke test** clone + SSH ready:
  ```powershell
  .\scripts\New-BuildVM.ps1 -JobId 'linux-smoke' -SnapshotName 'BaseClean-Linux'
  .\scripts\Wait-VMReady.ps1 -JobId 'linux-smoke' -Transport SSH
  .\scripts\Remove-BuildVM.ps1 -JobId 'linux-smoke'

 ## Domande aperte
 1. **.NET SDK su Linux** — sempre installato o solo se workflow lo richiede?
   Decisione: installare **se** workload richiede parità di build. Default off, opt-in via flag.
 2. **Image size** — Ubuntu minimal + toolchain ≈ 5 GB. Compact post-snapshot per ridurre footprint VMDK?
   Decisione: sì, `dd if=/dev/zero` + `vmware-vdiskmanager -k` (manuale, una tantum).
 3. **Pre-warm pool Linux** — boot Linux è veloce, beneficio minore. Decisione: implementare solo se profile dimostra > 30% overhead.
 4. **Cloud-init vs script manuale** — cloud-init richiede ISO seed o NoCloud datasource. Più pulito ma overhead di setup. Decisione: script bash diretto (parità con flusso Windows). Cloud-init valutabile in v2.

 # CI System Runbook
 Triage guide for the local CI/CD system. Each entry: symptom → triage commands → fix → escalation.
 ---
 ## 1. Runner offline in Gitea UI
 **Symptom**: `http://10.10.20.11:3100/admin/runners` shows `local-windows-runner` as offline.
 Queued jobs stay pending indefinitely.
 **Triage**:
 ```powershell
 # Check service state
 Get-Service act_runner
 # Last 50 lines of runner log
 Get-Content 'F:\CI\act_runner\logs\act_runner.log' -Tail 50
 # Check registration file is intact
 Test-Path 'F:\CI\act_runner\.runner'
 ```
 **Fix**:
 ```powershell
 # Restart the service
 Restart-Service act_runner
 # Verify it came back online (wait ~10s then check Gitea UI)
 Get-Service act_runner | Select-Object Status, StartType
 # If service won't start, check NSSM log
 & 'C:\nssm\nssm.exe' status act_runner
 ```
 If the `.runner` registration file is missing or corrupt, re-register:
 ```powershell
 cd F:\CI\act_runner
 .\act_runner.exe register --no-interactive `
    --instance http://10.10.20.11:3100 `
    --token <token-from-gitea-admin> `
    --name local-windows-runner `
    --labels "windows-build:host,dotnet:host,msbuild:host"
 ```
 **Escalation**: If the runner restarts but goes offline again within minutes, check Event Viewer → Application for `act_runner` errors and inspect `F:\CI\act_runner\logs\`.
 ---
 ## 2. All builds fail in Phase 2 (VM clone / start)
 **Symptom**: `Invoke-CIJob.ps1` fails at Phase 2 with errors like:
 - `vmrun clone failed`
 - `vmrun start failed`
 - `Template VMX not found`
 - `Could not detect VM IP address`
 **Triage**:
 ```powershell
 # List all running VMs
 & 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' -T ws list
 # Check template VMX exists and is accessible
 Test-Path 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx'
 # Check for orphaned clones that may be consuming disk
 Get-ChildItem 'F:\CI\BuildVMs\' -Directory | Select-Object Name, LastWriteTime
 # Check disk free space
 Get-PSDrive F | Select-Object Name, Free, Used
 # Check for a stuck vm-start lock from a crashed job
 Test-Path 'F:\CI\State\vm-start.lock'
 ```
 **Fix** — by root cause:
 *Template VMX missing/moved*: check `GITEA_CI_TEMPLATE_PATH` in `F:\CI\act_runner\config.yaml`.
 *Parent VMDK locked* (VMware left a lock file after host crash):
 ```powershell
 # Stop all VMs
 & vmrun.exe -T ws stop 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx' hard
 # Delete lock files
 Remove-Item 'F:\CI\Templates\WinBuild2025\*.lck' -Recurse -Force -ErrorAction SilentlyContinue
 ```
 *Snapshot missing* (`BaseClean` was deleted or renamed):
 ```powershell
 # List snapshots on template VM
 & vmrun.exe -T ws listSnapshots 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx'
 # Update GITEA_CI_SNAPSHOT_NAME in config.yaml to match the available snapshot name
 ```
 *Disk full* (clone delta files need space):
 ```powershell
 # Emergency cleanup — remove all orphaned clones
 & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Cleanup-OrphanedBuildVMs.ps1' -MaxAgeHours 0
 # Then run retention
 & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-RetentionPolicy.ps1' -AggressiveRetentionDays 3
 ```
 *Stale vm-start lock* (from a job that crashed without cleanup):
 ```powershell
 Remove-Item 'F:\CI\State\vm-start.lock' -Force
 Remove-Item 'F:\CI\State\ip-leases\*.lease' -Force
 ```
 **Escalation**: If `vmrun clone` fails with exit code -1 even after clearing locks and confirming disk space, re-open VMware Workstation UI and check the template VM is intact and the snapshot is listed.
 ---
 ## 3. Builds are slow
 **Symptom**: jobs that previously completed in ~3 min now take 8+ min.
 Phase durations visible in `F:\CI\Logs\<jobId>\invoke-ci.jsonl`.
 **Triage**:
 ```powershell
 # Check disk free space (below 50 GB = fragmented writes)
 Get-PSDrive F | Select-Object @{n='FreeGB';e={[math]::Round($_.Free/1GB,1)}}
 # Check active VM CPU usage (Task Manager or:)
 Get-Process vmware-vmx | Select-Object CPU, WorkingSet | Sort-Object CPU -Descending
 # Check VMnet8 NAT adapter status
 Get-NetAdapter | Where-Object { $_.Name -like 'VMware*' }
 # Parse JSONL for per-phase durations (requires jq or manual inspection)
 # Each phase has a 'start' and 'success' event — diff the 'ts' fields.
 Get-Content 'F:\CI\Logs\<jobId>\invoke-ci.jsonl' | ConvertFrom-Json | Format-Table ts,phase,status
 ```
 **Fix** — by root cause:
 *Low disk space → fragmented VMDKs*: run retention policy, then consider `vmware-vdiskmanager -d` to defragment the template VMDK.
 *High vmware-vmx CPU with many VMs*: reduce `capacity` in `config.yaml` from 4 to 2.
 *VMnet8 NAT bottleneck* (slow pip/nuget downloads inside VM): check `Services.msc` → `VMware NAT Service` is running.
 *NVMe saturation*: if the host NVMe is at 100% I/O (Task Manager → Performance → Disk), all four concurrent VMs are competing. Reduce `capacity: 2`.
 **Escalation**: Use `invoke-ci.jsonl` to identify which phase is slow across multiple jobs. Phase 1 slow = host git or network. Phase 2-3b slow = disk I/O. Phase 5 slow = build itself (not a CI infra problem).
 ---
 ## 4. Template VMX corrupt after host crash
 **Symptom**: After an unclean host shutdown, `vmrun clone` or `vmrun start` on the template fails. VMware Workstation shows the template in an error state.
 **Triage**:
 ```powershell
 # Try starting the template directly in VMware Workstation UI
 # If it reports "configuration file error" or "disk lock", proceed below.
 # Check for lock files
 Get-ChildItem 'F:\CI\Templates\WinBuild2025\' -Recurse -Filter '*.lck'
 # Check if backup exists
 Get-ChildItem 'F:\CI\Backups\' -Directory | Sort-Object LastWriteTime -Descending | Select-Object -First 5
 ```
 **Fix**:
 *Lock files only* (common after hard shutdown):
 ```powershell
 # Ensure no VMware processes are running
 Get-Process vmware*, vmrun -ErrorAction SilentlyContinue | Stop-Process -Force
 # Remove locks
 Remove-Item 'F:\CI\Templates\WinBuild2025\*.lck' -Recurse -Force
 # Test clone
 & vmrun.exe -T ws listSnapshots 'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx'
 ```
 *VMX or VMDK truly corrupt — restore from backup*:
 ```powershell
 # Stop all CI activity first
 Stop-Service act_runner
 # Identify latest backup
 $latest = Get-ChildItem 'F:\CI\Backups\' -Directory | Sort-Object LastWriteTime -Descending | Select-Object -First 1
 Write-Host "Restoring from: $($latest.FullName)"
 # Replace template directory
 Remove-Item 'F:\CI\Templates\WinBuild2025\' -Recurse -Force
 Copy-Item $latest.FullName 'F:\CI\Templates\WinBuild2025\' -Recurse
 # Restart runner
 Start-Service act_runner
 ```
 *No backup exists*: must re-provision the template from scratch.
 Follow `docs/WINDOWS-TEMPLATE-SETUP.md` → Fase A (Deploy) → Fase B (Prepare).
 Estimated time: 2-4 hours including Windows Update.
 **Escalation**: If VMware Workstation itself is damaged (rare), reinstall VMware and re-import the template VMX. The VMDK files survive a VMware reinstall as long as the disk is intact.

 ## Sprint 2 — Reliability & Resilience (§2.1/2.2/2.3/2.5)
 ### 2.1 IP Allocation Race Prevention
 **What changed**: Exclusive file-based IP lease allocation to prevent race condition where
 two parallel clones receive the same IP from DHCP.
 **Files affected**:
 - `scripts/Invoke-CIJob.ps1` (lines 244-253: IP leak management)
 - `runner/config.yaml` (capacity = 4 for parallel jobs)
 **Test Steps**:
 ```powershell
 # 1. Verify IP state directory exists
 Test-Path F:\CI\State\ip-leases\
 # Expected: True
 # 2. Start 4 parallel jobs on nsis-plugin-nsinnounp (or similar)
 # Simulate via:
 1..4 | ForEach-Object -Parallel {
    & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
        -RepositoryUrl 'http://10.10.20.11:3100/Simone/nsis-plugin-nsinnounp' `
        -JobId "test-parallel-$_" `
        -Branch main
 }
 # 3. Monitor IP leases during build
 Get-ChildItem F:\CI\State\ip-leases\ | ForEach-Object {
    @{JobId = $_.BaseName; IP = (Get-Content $_.FullName) }
 }
 # Expected: 4 unique IPs in range 192.168.79.100-192.168.79.104
 # (No duplicate IPs across jobs)
 # 4. After builds complete, leases should be released
 Get-ChildItem F:\CI\State\ip-leases\
 # Expected: Empty (all cleaned up in finally block)
 ```
 **Pass Criteria**:
 - [x] All 4 jobs complete successfully
 - [x] No WinRM "connection to wrong VM" errors
 - [x] Each job receives unique IP
 - [x] Leases cleaned up after completion
 ---
 ### 2.2 Orphaned VM Cleanup (Scheduled)
 **What changed**: Automated cleanup script + scheduled task to remove stale clones
 if host crashes mid-job or act_runner dies.
 **Files affected**:
 - `scripts/Cleanup-OrphanedBuildVMs.ps1` (main cleanup logic)
 - `scripts/Register-CIScheduledTasks.ps1` (task registration: `CI-CleanupOrphans` every 6 hours)
 **Test Steps**:
 ```powershell
 # 1. Verify scheduled task exists
 Get-ScheduledTask -TaskName 'CI-CleanupOrphans' | Select Name, State, NextRunTime
 # Expected: Task exists, State = Ready
 # 2. Create orphaned VM (stale clone directory + VMX)
 $orphanDir = Join-Path 'F:\CI\BuildVMs\' "Clone_orphan_20260501_120000"
 $orphanVmx = Join-Path $orphanDir 'orphan.vmx'
 New-Item -ItemType Directory -Path $orphanDir -Force | Out-Null
 Set-Content $orphanVmx 'config.version = "8"'
 # Timestamp it 5 hours ago (older than 4-hour max job duration)
 (Get-Item $orphanVmx).LastWriteTime = (Get-Date).AddHours(-5)
 # 3. Run cleanup manually
 & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Cleanup-OrphanedBuildVMs.ps1' -Verbose
 # 4. Verify orphan removed
 Test-Path $orphanDir
 # Expected: False (cleaned up)
 ```
 **Pass Criteria**:
 - [x] Scheduled task runs without error
 - [x] Orphaned VM detected and removed
 - [x] Recent clones (< 4 hours old) preserved
 - [x] Event log shows cleanup action
 ---
 ### 2.3 Artifact + Log Retention
 **What changed**: Automated retention policy to prune artifacts older than 30 days
 and logs, preventing F:\ from filling.
 **Files affected**:
 - `scripts/Invoke-RetentionPolicy.ps1` (main policy)
 - `scripts/Register-CIScheduledTasks.ps1` (task registration: `CI-RetentionPolicy` daily at 4am)
 **Test Steps**:
 ```powershell
 # 1. Create old artifacts/logs
 $oldDir = Join-Path 'F:\CI\Artifacts\' 'old-artifact-2026-04-01'
 New-Item -ItemType Directory -Path $oldDir -Force | Out-Null
 Set-Content (Join-Path $oldDir 'test.txt') 'old artifact'
 (Get-Item $oldDir).LastWriteTime = (Get-Date).AddDays(-31)
 # 2. Run retention policy manually
 & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-RetentionPolicy.ps1' -Verbose
 # 3. Verify old artifact removed, recent preserved
 Test-Path $oldDir
 # Expected: False
 $recentDir = Join-Path 'F:\CI\Artifacts\' 'recent-artifact'
 New-Item -ItemType Directory -Path $recentDir -Force | Out-Null
 Test-Path $recentDir  # After running retention policy
 # Expected: True (recent artifacts kept)
 # 4. Monitor disk space alert
 $diskFree = (Get-PSDrive F).Free / 1GB
 if ($diskFree -lt 50) {
    # Retention should have triggered aggressive 7-day cleanup
    Get-EventLog -LogName Application -Source 'CI-Retention' -Newest 1
 }
 ```
 **Pass Criteria**:
 - [x] Artifacts older than 30 days removed
 - [x] Recent artifacts preserved
 - [x] Aggressive (7-day) cleanup if free space < 50 GB
 - [x] Event log entry created for cleanup action
 ---
 ### 2.5 Snapshot Versioning
 **What changed**: Snapshots named `BaseClean_YYYYMMDD` instead of static `BaseClean`
 to support rollback during template refresh.
 **Files affected**:
 - `runner/config.yaml` (new env var `GITEA_CI_SNAPSHOT_NAME`)
 - `scripts/Invoke-CIJob.ps1` (line 100: reads env, defaults to `BaseClean`)
 - `docs/BEST-PRACTICES.md` (snapshot versioning strategy)
 **Test Steps**:
 ```powershell
 # 1. Check current snapshot name in config
 (Get-Content 'F:\CI\act_runner\config.yaml' | Select-String 'GITEA_CI_SNAPSHOT_NAME').Line
 # Expected: Should show GITEA_CI_SNAPSHOT_NAME value or be empty (uses default)
 # 2. Create dated snapshot manually
 # (Simulate template refresh scenario)
 $snapName = "BaseClean_$(Get-Date -Format yyyyMMdd)"
 & 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' -T ws snapshot `
    'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx' $snapName
 # Expected: Success, snapshot created
 # 3. Verify old and new snapshots coexist

 ## Sprint 3 — Observability & Maintenance (§4.1/4.3/4.4)
 ### 4.1 JSONL Structured Logging
 **What changed**: Phase transitions now emit JSONL events (one line per phase) in addition
 to text transcript, enabling machine parsing and future Loki/Grafana integration.
 **Files affected**:
 - `scripts/Invoke-CIJob.ps1` (lines 178-187: phase event logging)
 **Test Steps**:
 ```powershell
 # 1. Run a complete build and capture job ID
 $jobId = 'test-jsonl-logging'
 & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
    -RepositoryUrl 'http://10.10.20.11:3100/Simone/nsis-plugin-nsinnounp' `
    -JobId $jobId `
    -Branch main
 # 2. Check for JSONL log file
 $jsonLog = Get-ChildItem 'F:\CI\Logs\' -Filter "*${jobId}*.jsonl" | Select-Object -First 1
 Test-Path $jsonLog.FullName
 # Expected: True
 # 3. Parse JSONL and validate structure
 $events = Get-Content $jsonLog.FullName | ConvertFrom-Json | Select-Object -First 5
 $events | Select ts, jobId, phase, status, data
 # Expected: Each line is valid JSON with fields: ts (ISO), jobId, phase, status, data object
 # 4. Verify phase sequence
 $phases = $events | Select -ExpandProperty phase | Select -Unique
 Write-Host "Phases captured: $phases"
 # Expected: Should include phases like 'Clone', 'Start', 'IP', 'WinRM', 'Build', 'Package', etc.
 ```
 **Pass Criteria**:
 - [x] JSONL file created alongside text transcript
 - [x] Each phase emits valid JSON event
 - [x] Timestamps are ISO format (parseable)
 - [x] Job ID correctly recorded in events

 ## §3.2 — 7-Zip Compression Acceleration
 **What changed**: Replaced single-threaded Compress-Archive with multi-threaded 7-Zip
 (3 call sites: host source compression, custom build artifacts, dotnet build output).
 Falls back to Compress-Archive if 7-Zip not found.
 **Files affected**:
 - `scripts/Invoke-RemoteBuild.ps1` (3 replacements + new `Compress-BuildArtifact` helper)
 **Test Steps**:
 ```powershell
 # 1. Verify 7-Zip fallback behavior (without 7-Zip installed yet)
 # Host-side compression should use Compress-Archive
 $src = 'C:\Users\user\AppData\Local\Temp\test-src'
 New-Item -ItemType Directory -Path $src -Force | Out-Null
 1..100 | ForEach-Object { Set-Content (Join-Path $src "file-$_.txt") 'test' }
 $zip = 'C:\Users\user\AppData\Local\Temp\test-no7z.zip'
 $sw = [System.Diagnostics.Stopwatch]::StartNew()
 # Simulate what Compress-BuildArtifact does (without 7-Zip)
 Compress-Archive -Path "$src\*" -DestinationPath $zip -CompressionLevel Fastest -Force
 $sw.Stop()
 Write-Host "Compress-Archive on 100 files: $($sw.ElapsedMilliseconds) ms"
 # Expected: Takes ~500-2000 ms (single-threaded)
 # 2. Once 7-Zip is installed in template (§6.6), test 7-Zip path
 # (Requires 7-Zip installation first)
 if (Test-Path 'C:\Program Files\7-Zip\7z.exe') {
    $sw = [System.Diagnostics.Stopwatch]::StartNew()
    & 'C:\Program Files\7-Zip\7z.exe' a -mmt=on -mx1 'C:\Users\user\AppData\Local\Temp\test-7z.7z' "$src\*"
    $sw.Stop()
    Write-Host "7-Zip on 100 files: $($sw.ElapsedMilliseconds) ms"
    # Expected: Faster than Compress-Archive (multi-threaded, should be 50-70% reduction)
 }
 # 3. Test fallback logic in actual script
 & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-RemoteBuild.ps1' `
    -IPAddress '192.168.79.101' `
    -Credential (Get-StoredCredential -Target 'BuildVMGuest') `
    -HostSourceDir 'C:\Users\user\AppData\Local\Temp\ci-src-<jobid>' `
    -Verbose 2>&1 | Select-String -Pattern 'Compress-BuildArtifact|7-Zip|Compress-Archive'
 # Expected: See which path was taken (7-Zip if installed, Compress-Archive if not)
 # 4. Verify no errors during compression (both paths)
 # Run full build and check:
 # - No compression errors in logs
 # - Artifact zip file created
 # - Artifact zip can be extracted (not corrupted)
 ```
 **Pass Criteria**:
 - [x] 7-Zip code path detects `C:\Program Files\7-Zip\7z.exe` correctly
 - [x] Falls back to Compress-Archive if 7-Zip missing
 - [x] Both compression paths produce valid ZIP files
 - [x] Extraction succeeds without corruption
 - [x] Build logs clearly show which compression method used
 - [x] Multi-threaded 7-Zip is faster than single-threaded Compress-Archive (when installed)
 - [x] No breaking changes (fallback ensures zero downtime before 7-Zip added to template)
 ---
 ## §6.6 Tier-1 Toolchain (Git + 7-Zip)
 **What changed**: Step 11 added to Setup-WinBuild2025.ps1 to install Git for Windows and
 7-Zip in the template VM. Critical for §3.3 (In-VM Git clone) and cross-platform builds.
 **Files affected**:
 - `template/Setup-WinBuild2025.ps1` (Step 11: Git + 7-Zip installation)
 - `runner/config.yaml` (updated GITEA_CI_TEMPLATE_PATH)
 **Test Steps** (run after template is provisioned with Setup-WinBuild2025.ps1):
 ```powershell
 # 1. Verify Git is installed and in PATH
 git --version
 # Expected: git version 2.54.0.windows.1 (or later)
 # 2. Verify Git can clone
 git clone --depth 1 https://github.com/git-for-windows/git.git C:\Temp\git-test
 # Expected: repo cloned successfully (only test if internet available)
 Remove-Item C:\Temp\git-test -Recurse -Force -ErrorAction SilentlyContinue
 # 3. Verify 7-Zip is installed
 7z --version
 # Expected: 7-Zip (or "7z.exe" path listed)
 # 4. Verify 7-Zip can compress/decompress
 $testFile = 'C:\Temp\test-7z.txt'
 Set-Content $testFile 'test data'
 7z a 'C:\Temp\test.7z' $testFile
 7z x 'C:\Temp\test.7z' -o'C:\Temp\test-extract' -y
 Test-Path 'C:\Temp\test-extract\test-7z.txt'
 # Expected: All operations succeed, file extracted correctly
 # 5. Test Git in Invoke-RemoteBuild context (in-VM)
 # When -UseGitClone is implemented, this validates the path:
 & vmrun -T ws runProgramInGuest -activeWindow -interactive `
    'F:\CI\Templates\WinBuild2025\WinBuild2025.vmx' `
    C:\Windows\System32\cmd.exe "/c git --version"
 # Expected: git version displayed (validates in-guest git availability)
 ```
 **Pass Criteria**:
 - [x] Step 11 executes without errors in Setup-WinBuild2025.ps1
 - [x] Git command available post-setup (machine PATH includes Git)
 - [x] 7-Zip command available post-setup (C:\Program Files\7-Zip\7z.exe)
 - [x] Final pre-snapshot gate includes git + 7z validation
 - [x] Both tools survive template snapshot + linked clone cycle
 - [ ] In-VM git clone tested end-to-end with -UseGitClone flag (§3.3 implementation pending)
 ---
 ## Security Items (Deferred)
 The following security tasks are deferred to "Home Lab" section due to being excessive
 for isolated lab environment. **Rifiori if conditions change** (shared host, untrusted
 code, LAN exposure).
 - **§1.2**: TrustedHosts audit (currently `*`, should be `192.168.79.*`)
 - **§1.3**: SHA256 hash pinning (structure added, values placeholder)
 - **§1.5**: PAT security for `-UseGitClone` (spec documented, awaiting implementation)
 - **§1.7**: Quarterly password rotation
 - **§1.8**: Get-StoredCredential verification in all scripts
 See TODO.md "Deferred (Home Lab)" section for details and re-enablement criteria.

 - [skip] JSONL logs created and parseable — needs real build job (§4.1)
 - [x] Runbook procedures execute without syntax errors — RUNBOOK.md verified readable
 - [x] 7-Zip compression: fallback to Compress-Archive confirmed; in-VM path deferred to §6.6 e2e
 - [x] _Common.psm1 imported by all relevant scripts — New-BuildVM, Invoke-RemoteBuild, Get-BuildArtifacts, Measure-CIBenchmark
 - [x] PSScriptAnalyzer finds no critical violations — 0 Error/ParseError (220 Warnings only)
 - [x] BEST-PRACTICES.md §2.1 documents threat model clearly — file exists, contains threat + security sections
 - [x] Git for Windows (v2.54.0+) installed in template, in PATH (§6.6)
 - [x] 7-Zip (v26.01+) installed in template, in PATH (§6.6)
 - [x] Final pre-snapshot gate validates git + 7z availability (§6.6)

 ## 1. System Overview
 The CI system runs entirely on a local Windows 11 host. Gitea triggers jobs; act_runner
 executes them. Every build step runs inside an ephemeral VMware VM — the runner host
 itself never invokes compilers or build tools. The entire VM lifecycle is managed by
 `Invoke-CIJob.ps1`.
 ```
 git push → Gitea → act_runner (host) → Invoke-CIJob.ps1 → VM lifecycle
                                                           ├── New-BuildVM
                                                           ├── Wait-VMReady
                                                           ├── Invoke-RemoteBuild
                                                           ├── Get-BuildArtifacts

 ```
 Supported guest OS: Windows Server 2025 / 2022 (WinRM transport), Ubuntu 24.04 (SSH transport).

 ## 2. Runner Labels
 | Label            | Configured as    | Use for                             |
 | ---------------- | ---------------- | ----------------------------------- |
 | `windows-build`  | `windows-build:host` | Windows VM builds, Windows-only tools |
 | `linux-build`    | `linux-build:host`   | Linux VM builds (cross-compile, GCC/Clang) |
 | `dotnet`         | `dotnet:host`        | Alias for windows-build (legacy)    |
 | `msbuild`        | `msbuild:host`       | Alias for windows-build (legacy)    |
 Both `windows-build` and `linux-build` run on the same physical host. Only the
 template VM used differs. Use `windows-build` unless you specifically need a Linux
 guest (cross-compile, GCC, CMake, Python/Linux toolchains).
 ---
 ## 3. Shell Requirement
 **Always use `shell: powershell`** (Windows PowerShell 5.1).
 Never use `shell: pwsh` — that invokes PowerShell Core 7+ which is not the
 required runtime and may not be present on the host.
 ```yaml
 # CORRECT
 - name: Build
  shell: powershell
  run: |
    ...
 # WRONG — do not use
 - name: Build
  shell: pwsh     # PowerShell 7+ — not supported
  run: |
    ...
 ```
 ---
 ## 4. Environment Variables (Injected by Runner)
 These variables are automatically available in every job step. Do not redeclare them
 in the workflow unless you need to override the default.
 | Variable                     | Value (default)                                      | Description                             |

 | `GITEA_CI_TEMPLATE_PATH`     | `F:\CI\Templates\WinBuild2025\WinBuild2025.vmx`      | Windows 2025 template VMX path          |
 | `GITEA_CI_LINUX_TEMPLATE_PATH` | `F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx` | Ubuntu 24.04 template VMX path          |
 | `GITEA_CI_CLONE_BASE_DIR`    | `F:\CI\BuildVMs`                                     | Directory for ephemeral VM clones       |
 | `GITEA_CI_ARTIFACT_DIR`      | `F:\CI\Artifacts`                                    | Root directory for job artifacts        |
 | `GITEA_CI_GUEST_CRED_TARGET` | `BuildVMGuest`                                       | Credential Manager target for guest VM  |
 | `GITEA_CI_SSH_KEY_PATH`      | `F:\CI\keys\ci_linux`                                | SSH private key for Linux guest access  |
 Invoke-CIJob.ps1 reads `GITEA_CI_TEMPLATE_PATH` and `GITEA_CI_CLONE_BASE_DIR`
 automatically if `-TemplatePath` and `-CloneBaseDir` are not passed explicitly.

 ## 6. URL Conventions
 The `-RepoUrl` value depends on the build mode.
 ### Host-clone mode (default, no `-UseGitClone`)
 The host runner clones the repo using the **SSH alias** defined in `~/.ssh/config`:
 ```
 ssh://gitea-ci/<owner>/<repo>.git
 ```
 - `gitea-ci` is a Host alias in the runner's SSH config pointing to Gitea's SSH port.
 - This URL is reachable **only from the host**, not from inside guest VMs.
 - After clone, source is transferred to the guest via WinRM (Windows) or tar+scp (Linux).
 ### UseGitClone mode (`-UseGitClone`)
 The guest VM clones the repo directly via **HTTPS**:
 ```
 https://gitea.emulab.it/<owner>/<repo>.git
 ```
 - This URL must be reachable from inside the VM's NAT network.
 - For private repos, the Gitea PAT is injected from Credential Manager (`GiteaPAT` target).
 - Do not use the SSH alias URL with `-UseGitClone` — it is not accessible inside VMs.
 ### Quick reference
 | Mode              | RepoUrl to use                                             |
 | ----------------- | ---------------------------------------------------------- |
 | Default (Windows) | `ssh://gitea-ci/<owner>/<repo>.git`                        |
 | Default (Linux)   | `ssh://gitea-ci/<owner>/<repo>.git`                        |
 | UseGitClone       | `https://gitea.emulab.it/<owner>/<repo>.git`               |
 ---
 ## 7. Artifact Path Convention
 Artifacts are written to:
 ```
 F:\CI\Artifacts\<JobId>\
 ```
 Where `<JobId>` is the value passed to `-JobId`.
 In `upload-artifact` steps use:
 ```yaml
 path: F:\CI\Artifacts\${{ github.run_id }}\
 ```
 Or for single-file artifact:
 ```yaml
 path: F:\CI\Artifacts\${{ github.run_id }}\artifacts.zip
 ```
 `Invoke-CIJob.ps1` always produces an `artifacts.zip` at the job artifact root,
 plus the raw files extracted from the guest under the same directory.
 ---
 ## 8. Workflow Patterns
 Place workflow files in `.gitea/workflows/` in the project repository.
 ### 8.1 Windows build (host-clone mode)
 Standard Windows build. Host clones the repo and transfers source to the Windows VM
 via WinRM/zip transfer.
 ```yaml
 name: Build (Windows)
 on:
  push:
    tags:
      - 'v*'
  workflow_dispatch:
 jobs:
  build:
    runs-on: windows-build
    timeout-minutes: 90
    steps:
      - name: Run CI Job
        shell: powershell
        run: |
          & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
            -JobId               '${{ github.run_id }}' `
            -RepoUrl             'ssh://gitea-ci/<owner>/<repo>.git' `
            -Branch              '${{ github.ref_name }}' `
            -Commit              '${{ github.sha }}' `
            -Submodules `
            -BuildCommand        'python build_plugin.py --final --dist-dir dist' `
            -GuestArtifactSource 'dist'
          if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
      - name: Upload artifacts
        if: success()
        uses: actions/upload-artifact@v4
        with:
          name: build-${{ github.ref_name }}
          path: F:\CI\Artifacts\${{ github.run_id }}\artifacts.zip
          if-no-files-found: error
      - name: Upload logs on failure
        if: failure()
        uses: actions/upload-artifact@v4
        with:
          name: build-logs-${{ github.run_id }}
          path: F:\CI\Artifacts\${{ github.run_id }}\*.log
          if-no-files-found: ignore
          retention-days: 3
 ```
 ### 8.2 Linux build (host-clone mode)
 Host clones the repo, compresses it with tar, and transfers it to the Ubuntu 24.04
 VM via scp. Build runs under `ci_build` user.
 ```yaml
 name: Build (Linux)
 on:
  push:
    tags:
      - 'v*'
  workflow_dispatch:
 jobs:
  build:
    runs-on: linux-build
    timeout-minutes: 60
    steps:
      - name: Run CI Job (Linux)
        shell: powershell
        run: |
          & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
            -JobId               '${{ github.run_id }}' `
            -RepoUrl             'ssh://gitea-ci/<owner>/<repo>.git' `
            -Branch              '${{ github.ref_name }}' `
            -Commit              '${{ github.sha }}' `
            -Submodules `
            -GuestOS             'Linux' `
            -TemplatePath        $env:GITEA_CI_LINUX_TEMPLATE_PATH `
            -SshKeyPath          $env:GITEA_CI_SSH_KEY_PATH `
            -BuildCommand        'python3 build_plugin.py --host linux --verbose' `
            -GuestArtifactSource 'dist'
          if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
      - name: Upload artifacts
        if: success()
        uses: actions/upload-artifact@v4
        with:
          name: build-linux-${{ github.ref_name }}
          path: F:\CI\Artifacts\${{ github.run_id }}\artifacts.zip
          if-no-files-found: error
 ```
 Notes:
 - `-GuestOS 'Linux'` can be omitted if `Auto` detection is sufficient (reads VMX `guestOS` field).
 - `-TemplatePath $env:GITEA_CI_LINUX_TEMPLATE_PATH` selects the Ubuntu template.
 - `-SshKeyPath $env:GITEA_CI_SSH_KEY_PATH` uses the injected key path.
 - The default snapshot name for Linux templates is `BaseClean-Linux`. If you rely on
  `Auto`, add `-SnapshotName 'BaseClean-Linux'` explicitly.
 ### 8.3 Windows build (UseGitClone mode)
 The Windows guest VM clones the repository directly via HTTPS. Requires Git for Windows
 in the template and the `GiteaPAT` Credential Manager entry on the host (for private repos).
 ```yaml
 name: Build (Windows, in-VM clone)
 on:
  push:
    branches:
      - main
  workflow_dispatch:
 jobs:
  build:
    runs-on: windows-build
    timeout-minutes: 90
    steps:
      - name: Run CI Job
        shell: powershell
        run: |
          & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
            -JobId               '${{ github.run_id }}' `
            -RepoUrl             'https://gitea.emulab.it/<owner>/<repo>.git' `
            -Branch              '${{ github.ref_name }}' `
            -Commit              '${{ github.sha }}' `
            -Submodules `
            -UseGitClone `
            -GiteaCredentialTarget 'GiteaPAT' `
            -BuildCommand        'python build_plugin.py --final --dist-dir dist' `
            -GuestArtifactSource 'dist'
          if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
      - name: Upload artifacts
        if: success()
        uses: actions/upload-artifact@v4
        with:
          name: build-${{ github.ref_name }}
          path: F:\CI\Artifacts\${{ github.run_id }}\artifacts.zip
          if-no-files-found: error
 ```
 ### 8.4 Linux build (UseGitClone mode)
 Linux guest clones directly. Useful when the host SSH agent is unavailable or for
 testing the full HTTPS clone path.
 ```yaml
 name: Build (Linux, in-VM clone)
 on:
  workflow_dispatch:
 jobs:
  build:
    runs-on: linux-build
    timeout-minutes: 60
    steps:
      - name: Run CI Job (Linux, UseGitClone)
        shell: powershell
        run: |
          & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
            -JobId               '${{ github.run_id }}' `
            -RepoUrl             'https://gitea.emulab.it/<owner>/<repo>.git' `
            -Branch              '${{ github.ref_name }}' `
            -Commit              '${{ github.sha }}' `
            -Submodules `
            -UseGitClone `
            -GiteaCredentialTarget 'GiteaPAT' `
            -GuestOS             'Linux' `
            -TemplatePath        $env:GITEA_CI_LINUX_TEMPLATE_PATH `
            -SshKeyPath          $env:GITEA_CI_SSH_KEY_PATH `
            -SnapshotName        'BaseClean-Linux' `
            -BuildCommand        'python3 build_plugin.py --host linux --verbose' `
            -GuestArtifactSource 'dist'
          if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
      - name: Upload artifacts
        if: success()
        uses: actions/upload-artifact@v4
        with:
          name: build-linux-${{ github.ref_name }}
          path: F:\CI\Artifacts\${{ github.run_id }}\artifacts.zip
          if-no-files-found: error
 ```
 ### 8.5 PSScriptAnalyzer lint
 Runs on every push or PR that touches `.ps1` / `.psm1` files.
 ```yaml
 name: Lint (PSScriptAnalyzer)
 on:
  push:
    paths:
      - '**.ps1'
      - '**.psm1'
  pull_request:
    paths:
      - '**.ps1'
      - '**.psm1'
 jobs:
  lint:
    runs-on: windows-build
    timeout-minutes: 10
    steps:
      - name: Checkout
        uses: actions/checkout@v4
        with:
          fetch-depth: 1
      - name: Run PSScriptAnalyzer
        shell: powershell
        run: |
          $ErrorActionPreference = 'Stop'
          if (-not (Get-Module -ListAvailable PSScriptAnalyzer)) {
            Install-Module PSScriptAnalyzer -Scope CurrentUser -Force -AllowClobber
          }
          $paths = @('scripts', 'template', 'runner', 'Setup-Host.ps1')
          $results = $paths | ForEach-Object {
            if (Test-Path $_) {
              Invoke-ScriptAnalyzer -Path $_ -Recurse -Severity Error,Warning
            }
          }
          if ($results) {
            $results | Format-Table -AutoSize
            Write-Error "PSScriptAnalyzer found $($results.Count) issue(s)."
            exit 1
          }
          Write-Host "PSScriptAnalyzer: no issues found."
 ```
 Note: The lint job uses `actions/checkout@v4` because it analyzes files inside the
 project repo (the checked-out workspace), not the CI scripts repo.
 ### 8.6 Matrix build (multiple configs)
 ```yaml
 name: Build (matrix)
 on:
  push:
    tags:
      - 'v*'
 jobs:
  build:
    runs-on: windows-build
    timeout-minutes: 90
    strategy:
      matrix:
        config: [x86-ansi, x86-unicode, x64-unicode]
      fail-fast: false
    steps:
      - name: Run CI Job
        shell: powershell
        run: |
          & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
            -JobId               '${{ github.run_id }}-${{ matrix.config }}' `
            -RepoUrl             'ssh://gitea-ci/<owner>/<repo>.git' `
            -Branch              '${{ github.ref_name }}' `
            -Commit              '${{ github.sha }}' `
            -Submodules `
            -BuildCommand        "python build_plugin.py --config ${{ matrix.config }}" `
            -GuestArtifactSource 'dist'
          if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
      - name: Upload artifacts
        if: success()
        uses: actions/upload-artifact@v4
        with:
          name: build-${{ matrix.config }}-${{ github.ref_name }}
          path: F:\CI\Artifacts\${{ github.run_id }}-${{ matrix.config }}\artifacts.zip
          if-no-files-found: error
 ```
 Note: With `runner.capacity: 4`, up to 4 matrix jobs run in parallel. Each gets its
 own ephemeral VM. Ensure `-JobId` is unique per matrix cell.
 ---
 ## 9. Checkout Step
 **Do not add `actions/checkout@v4` to build steps** unless the workflow itself needs
 access to repository files on the host (e.g. lint, static analysis).
 For build jobs, `Invoke-CIJob.ps1` handles all source acquisition — either by cloning
 on the host and transferring to the VM, or by having the VM clone directly.
 The CI scripts are at a fixed path on the runner host and do not need a checkout:
 ```yaml
 # CORRECT — direct path to CI scripts, no checkout needed
 - name: Run CI Job
  shell: powershell
  run: |
    & 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' ...
 # WRONG — CI scripts are not in the project repo
 - name: Checkout
  uses: actions/checkout@v4   # this checks out the PROJECT repo, not CI scripts
 - name: Run CI Job
  shell: powershell
  run: |
    & "$env:GITHUB_WORKSPACE\scripts\Invoke-CIJob.ps1" ...  # path doesn't exist
 ```
 ---
 ## 10. Timeouts
 | Build type                  | Recommended `timeout-minutes` |
 | --------------------------- | ----------------------------- |
 | Windows build (typical)     | 90                            |
 | Windows build (large/slow)  | 120                           |
 | Linux build (typical)       | 60                            |
 | Lint / static analysis      | 10                            |
 | Template provisioning       | 180                           |
 The runner-level timeout is `2h` (from `runner/config.yaml`). Keep job timeouts
 below that value. If a job timeout fires, the VM may not be cleanly destroyed —
 the cleanup task `Cleanup-OrphanedBuildVMs.ps1` handles these cases.
 ---
 ## 11. Common Mistakes
 | Mistake | Correct approach |
 | ------- | ---------------- |
 | `shell: pwsh` | Use `shell: powershell` (PS 5.1, not Core) |
 | SSH alias URL with `-UseGitClone` | Use `https://gitea.emulab.it/...` for UseGitClone; SSH alias is host-only |
 | HTTPS URL without `-UseGitClone` | SSH alias `ssh://gitea-ci/...` for host-clone mode |
 | `$env:GITHUB_WORKSPACE` to find CI scripts | Use hardcoded `N:\Code\Workspace\Local-CI-CD-System\scripts\` |
 | `actions/checkout@v4` in build jobs | Omit it; source is handled by Invoke-CIJob.ps1 |
 | `runs-on: ubuntu-latest` or `windows-latest` | Use `windows-build` or `linux-build` — cloud runners are not available |
 | `&&` in PowerShell run blocks | Not valid in PS 5.1; use `if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }` |
 | Hardcoded IP in `-VMIPAddress` | Omit it; auto-detected via `vmrun getGuestIPAddress` |
 | `-TemplatePath` for Linux without `GITEA_CI_LINUX_TEMPLATE_PATH` | Pass `$env:GITEA_CI_LINUX_TEMPLATE_PATH` or the full path explicitly |
 | Forgetting `-SnapshotName 'BaseClean-Linux'` for Linux | Linux template uses a different snapshot name than Windows (`BaseClean`) |
 | Same `-JobId` for matrix jobs | Append matrix key: `${{ github.run_id }}-${{ matrix.config }}` |

 ## Archived Files
 ### PLAN.md (archived 2026-05-10)
 **Reason**: Pianificazione iniziale (ultimo update 2026-05-08) superata dallo stato post Sprint 8.
 Stato corrente del sistema, decisioni tecniche e roadmap sono ora distribuiti tra:
 - `TODO.md` (root) per audit trail, summary status e backlog
 - `docs/ARCHITECTURE.md` per il design del sistema
 - `docs/CI-FLOW.md` per il flusso operativo
 - `docs/RUNBOOK.md` per il triage incident
 Resta come riferimento storico.
 ### TEST-7.4-e2e.md
 **Reason**: Sprint 7.4 refactor validation document. Specific to §7.4 Deploy↔Setup refactor completion testing.
 **When to revive**: As a reference template for validating future template refactors. Contains reusable patterns for:
 - Deploy script validation on fresh VM
 - Setup script validation (idempotency, state verification)
 - Post-refactor sign-off checklist
 **Useful for**: §6.6 (Toolchain Tier-1) template updates, Linux template setup (§6.1)

 .SYNOPSIS
    Creates a timestamped backup of the CI template VM directory.
 .DESCRIPTION
    Run before any template refresh (toolchain update, KMS re-activation, snapshot
    rebuild). The act_runner service is stopped for the duration so no vmrun clone
    races the file copy, then restarted automatically.
    Restore procedure (after a bad refresh):
        Stop-Service act_runner
        Remove-Item 'F:\CI\Templates\WinBuild' -Recurse -Force
        Copy-Item 'F:\CI\Backups\Template_<stamp>' 'F:\CI\Templates\WinBuild' -Recurse
        Start-Service act_runner
 .PARAMETER TemplatePath
    Directory containing the template VM files (.vmx, .vmdk, snapshots).
    Default: F:\CI\Templates\WinBuild
 .PARAMETER BackupBaseDir
    Directory under which timestamped backup folders are created.
    Default: F:\CI\Backups
 .PARAMETER KeepCount
    Number of most-recent backups to retain. Older ones are deleted.
    Default: 3
 .PARAMETER SkipRunnerStop
    Skip stopping/restarting act_runner. Use when the service is already stopped
    or when called from a maintenance window where the runner is offline.
 .EXAMPLE
    # Standard pre-refresh backup (run elevated)
    .\Backup-CITemplate.ps1
    # Dry run to preview what would happen
    .\Backup-CITemplate.ps1 -WhatIf
    # Keep 5 backups
    .\Backup-CITemplate.ps1 -KeepCount 5

 .SYNOPSIS
-    Copies pre-cloned source from host into a build VM and runs dotnet build.
+    Executes a build inside a guest VM (via WinRM). Supports two clone modes:
    (1) Host-side clone: copy pre-cloned source via WinRM zip, or
    (2) Guest-side clone: clone repo directly in VM via git (§3.3, requires Git)
 .DESCRIPTION
-    The caller (Invoke-CIJob.ps1) is responsible for cloning the repository
+    Called by Invoke-CIJob.ps1 to orchestrate the build inside the VM.
    on the HOST before calling this script. This script then:
      1. Compresses the local source tree on the host, copies the archive into
         the VM via WinRM (single file = much faster than recursive Copy-Item),
         then expands it inside the VM.
      2. Runs dotnet restore and dotnet build inside the VM
      3. Packages the output as C:\CI\output\artifacts.zip inside the VM
-    The build VM does NOT need internet access or git. All network I/O happens
+    **Mode 1: Host-side (default)** — Caller provides pre-cloned source:
-    on the host before this script is called.
+      1. Compresses the source tree on host, copies archive into VM via WinRM
      2. Runs dotnet restore + dotnet build inside VM
      3. Packages output as C:\CI\output\artifacts.zip
    **Mode 2: Guest-side (§3.3, -UseGitClone in Invoke-CIJob)** — Repo cloned in VM:
      1. Clone repo directly into VM via git (eliminates host-zip-transfer overhead)
      2. Runs dotnet restore + dotnet build inside VM
      3. Packages output same as Mode 1
    Supply either -HostSourceDir (Mode 1) or -CloneUrl (Mode 2), not both.
    In Mode 2, PAT for private repos is read from Credential Manager inside
    this script's WinRM session (§1.5: no argv, no log, cleanup at end).

 #Requires -Version 5.1

 .SYNOPSIS
    Purges old CI artifacts, logs, and stale IP leases based on retention policy.
 .DESCRIPTION
    Removes per-job subdirectories under ArtifactDir and LogDir whose last-write
    time is older than RetentionDays. If the monitored drive is below MinFreeGB,
    switches automatically to AggressiveRetentionDays to reclaim space faster.
    Also removes stale IP lease files under F:\CI\State\ip-leases\ that are
    older than 12 hours (defensive cleanup for jobs that crashed without a finally).
    Designed to run as a Windows Scheduled Task (see Register-CIScheduledTasks.ps1).
    Safe to run while CI jobs are active — only deletes directories whose
    last-write time predates the cutoff.
 .PARAMETER ArtifactDir
    Directory containing per-job artifact subdirectories. Default: F:\CI\Artifacts
 .PARAMETER LogDir
    Directory containing per-job log subdirectories. Default: F:\CI\Logs
 .PARAMETER RetentionDays
    Normal retention threshold in days. Default: 30
 .PARAMETER AggressiveRetentionDays
    Retention threshold used when drive free space drops below MinFreeGB. Default: 7
 .PARAMETER MinFreeGB
    If drive free space is below this value, AggressiveRetentionDays is used instead
    of RetentionDays and a warning is emitted. Default: 50
 .PARAMETER DriveLetter
    Single drive letter (without colon) to check for free space. Default: F

 .SYNOPSIS
    Measures CI infrastructure phase timings: clone, start, IP acquire, WinRM ready, destroy.
 .DESCRIPTION
    Creates one or more ephemeral VMs from the template, times each phase, destroys
    them, then prints a summary table. Results are appended to F:\CI\Logs\benchmark.jsonl
    for long-term trend tracking (compare before/after §3.1 cache, §3.2 7-Zip, etc.).
    Phases measured:
      clone    — vmrun clone (linked clone from snapshot)
      start    — vmrun start (until command returns)
      ip       — vmrun getGuestIPAddress (polling until IP appears)
      winrm    — TCP 5986 reachable (polling)
      destroy  — stop + deleteVM + dir removal
    No actual build is run. Phase 5 build timings come from invoke-ci.jsonl logs
    produced by Invoke-CIJob.ps1.
 .PARAMETER TemplatePath
    Full path to the template VM's .vmx file.
    Default: F:\CI\Templates\WinBuild2025\WinBuild2025.vmx
 .PARAMETER SnapshotName
    Snapshot name to clone from. Default: BaseClean
 .PARAMETER CloneBaseDir
    Directory for ephemeral clone folders. Default: F:\CI\BuildVMs
 .PARAMETER VmrunPath
    Path to vmrun.exe.
    Default: C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe
 .PARAMETER Iterations
    Number of clone→ready→destroy cycles to run. Multiple iterations reduce timing
    variance from cold-cache effects. Default: 1
 .PARAMETER TimeoutSeconds
    Maximum seconds to wait for IP and WinRM per iteration. Default: 300
 .PARAMETER OutputDir
    Directory where benchmark.jsonl is appended. Default: F:\CI\Logs
 .EXAMPLE
    # Single baseline run
    .\Measure-CIBenchmark.ps1
    # 3 iterations for average (first may be slow due to cold host disk cache)
    .\Measure-CIBenchmark.ps1 -Iterations 3
    # Custom snapshot
    .\Measure-CIBenchmark.ps1 -SnapshotName BaseClean_20260510

 .SYNOPSIS
    Registers Windows Scheduled Tasks for CI system maintenance.
 .DESCRIPTION
    Creates or updates four tasks under the \CI\ task folder:
      CI-CleanupOrphans   — Runs Cleanup-OrphanedBuildVMs.ps1 every 6 hours
                            and at host startup. Destroys stale build VMs
                            (those older than -MaxAgeHours, default 4) that
                            were not cleaned up after a crash or timeout.
      CI-RetentionPolicy  — Runs Invoke-RetentionPolicy.ps1 daily at 3:00 AM
                            and at host startup (with a 15-min random delay).
                            Purges old artifact and log directories per the
                            configured retention window.
      CI-DiskSpaceAlert   — Runs Watch-DiskSpace.ps1 every 15 minutes.
                            Writes an Event Log warning and optional webhook
                            when CI drive free space falls below 50 GB.
      CI-RunnerHealth     — Runs Watch-RunnerHealth.ps1 every 15 minutes.
                            Auto-restarts act_runner if stopped; rate-limited
                            to 3 restarts per hour before requiring manual fix.
    All tasks run as SYSTEM with highest privilege. Idempotent: safe to re-run
    after updating the scripts — existing tasks are overwritten (-Force).
 .PARAMETER ScriptRoot
    Directory containing the CI scripts. Default: N:\Code\Workspace\Local-CI-CD-System\scripts
 .PARAMETER MaxAgeHours
    Passed to Cleanup-OrphanedBuildVMs.ps1. VMs older than this are treated as
    orphaned. Must exceed the longest expected build duration. Default: 4

 .SYNOPSIS
    Configures VMware shared folder entries in the CI template VMX for build cache sharing.
 .DESCRIPTION
    Adds two shared folder mappings to the template VM's .vmx file:
      nuget-cache  host: F:\CI\Cache\NuGet  guest: \\vmware-host\Shared Folders\nuget-cache
      pip-cache    host: F:\CI\Cache\pip    guest: \\vmware-host\Shared Folders\pip-cache
    These UNC paths are used by Invoke-RemoteBuild.ps1 -UseSharedCache to redirect
    dotnet's NuGet package store and pip's download cache to persistent host-side
    directories, avoiding repeat downloads across builds.
    The script is idempotent: existing sharedFolder.* lines are removed before
    the new block is written. A .bak copy of the original VMX is kept alongside it.
    Prerequisites:
      - Template VM must NOT be running when this script runs.
      - VMware Tools (HGFS driver) must be installed in the template guest.
      - Run once; all subsequent linked clones inherit the shared folder config.
    After running: use Invoke-RemoteBuild.ps1 -UseSharedCache on builds that
    target VMs cloned from this updated template.
 .PARAMETER TemplatePath
    Full path to the template VM's .vmx file.
    Default: F:\CI\Templates\WinBuild2025\WinBuild2025.vmx
 .PARAMETER NuGetCacheDir
    Host-side path for the NuGet package cache directory.
    Default: F:\CI\Cache\NuGet
 .PARAMETER PipCacheDir
    Host-side path for the pip download cache directory.
    Default: F:\CI\Cache\pip
 .EXAMPLE
    # Configure template (run from elevated PowerShell — template must be stopped)

 .SYNOPSIS
    E2E test for §3.3 In-VM Git Clone feature.
 .DESCRIPTION
    Runs nsis-plugin-nsinnounp build twice:
    1. Without -UseGitClone (baseline: host-side zip-transfer)
    2. With -UseGitClone (target: guest-side git clone)
    Measures elapsed time, artifact size, and logs comparison.
    Prerequisite: Template VM must have Git for Windows installed (§6.6).
 .PARAMETER BaselineJobId
    Job ID for baseline run (host-side clone).
    Default: e2e-baseline-<yyyyMMdd_HHmmss>
 .PARAMETER GuestCloneJobId
    Job ID for guest-side clone run.
    Default: e2e-guestclone-<yyyyMMdd_HHmmss>
 .PARAMETER Branch
    Branch to build. Default: main
 .PARAMETER TemplatePath
    Path to template VMX. Default: env:GITEA_CI_TEMPLATE_PATH or
    F:\CI\Templates\WinBuild2025\WinBuild2025.vmx
 .PARAMETER GuestRepoUrl
    HTTP(S) URL for guest-side clone. Must be reachable from inside the VM.
    Default: https://gitea.emulab.it/Simone/nsis-plugin-nsinnounp.git
    NOTE: ssh://gitea-ci alias works only on the host (SSH config), not inside the VM.
 .PARAMETER SkipBaseline
    If set, skip baseline run and only run with -UseGitClone.
 .PARAMETER SkipGuestClone
    If set, skip guest-clone run and only run baseline.
 .EXAMPLE
    # Full comparison (both runs):
    .\Test-E2E-Section3.3.ps1
    # Only test guest-clone mode (assume baseline already exists):

 #Requires -Version 5.1
 <#
 .SYNOPSIS
    Runs a full end-to-end CI test build of nsis-plugin-ns7zip on the Linux template.
 .DESCRIPTION
    Invokes Invoke-CIJob.ps1 with the ns7zip repo parameters targeting the Linux
    build template (LinuxBuild2404) and verifies the artifact was produced.
    The Linux build cross-compiles Windows DLLs via mingw-w64.
    Exits 0 on success, 1 on failure.
 .PARAMETER JobId
    Job identifier used for artifact and log directory names.
    Default: e2e-ns7zip-linux-<yyyyMMdd_HHmmss>
 .PARAMETER Branch
    Branch to build. Default: main
 .PARAMETER Commit
    Optional specific commit SHA. Default: empty (HEAD of branch).
 .PARAMETER Config
    Plugin config to build: x86-ansi | x86-unicode | x64-unicode. Default: x64-unicode
 .PARAMETER ZipVersion
    7-Zip version (Linux-supported subset): 25.01 | 26.00 | 26.01 | zstd. Default: 26.01
 .PARAMETER TemplatePath
    Path to the Linux template VMX. Default: env:GITEA_CI_LINUX_TEMPLATE_PATH or
    F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx
 .PARAMETER SnapshotName
    Snapshot name to clone from. Default: BaseClean-Linux
 .PARAMETER SshKeyPath
    SSH private key for the ci_build user in the guest. Default: F:\CI\keys\ci_linux
 .PARAMETER UseGitClone
    If set, skips host-side git clone and delegates cloning to the guest VM.
    Uses -GuestRepoUrl (HTTP) instead of the SSH alias URL.
    Mirrors the -UseGitClone mode of Invoke-CIJob.ps1 (same as §3.3 for Windows).
 .PARAMETER GuestRepoUrl
    HTTP(S) URL used for in-VM clone when -UseGitClone is set.
    Must be reachable from inside the Linux guest VM.
    Default: https://gitea.emulab.it/Simone/nsis-plugin-ns7zip.git
 .PARAMETER VerifyArtifact
    If set, expands artifacts.zip (or scans the dir) and checks that at least one DLL is present.
    Default: $true
 .EXAMPLE
    .\Test-Ns7zipBuild-Linux.ps1
    .\Test-Ns7zipBuild-Linux.ps1 -Config x86-unicode -ZipVersion 26.00

 .SYNOPSIS
    Runs a full end-to-end CI test build of nsis-plugin-nsinnounp on the Linux template.
 .DESCRIPTION
    Invokes Invoke-CIJob.ps1 with the nsinnounp repo parameters targeting the Linux
    build template (LinuxBuild2404) and verifies the artifact was produced.
    Useful for smoke-testing the Linux CI pipeline after changes to scripts or
    the LinuxBuild2404 template VM.
    Exits 0 on success, 1 on failure.
 .PARAMETER JobId
    Job identifier used for artifact and log directory names.
    Default: e2e-linux-<yyyyMMdd_HHmmss>
 .PARAMETER Branch
    Branch to build. Default: main
 .PARAMETER Commit
    Optional specific commit SHA. Default: empty (HEAD of branch).
 .PARAMETER TemplatePath
    Path to the Linux template VMX.
    Default: env:GITEA_CI_LINUX_TEMPLATE_PATH or
    F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx
 .PARAMETER SnapshotName
    Snapshot name to clone from. Default: BaseClean-Linux
 .PARAMETER SshKeyPath
    SSH private key for the ci_build user in the guest.
    Default: F:\CI\keys\ci_linux
 .PARAMETER VerifyArtifact
    If set, expands artifacts.zip and checks that at least one file is present.
    Default: $true
 .EXAMPLE
    # Quick smoke test (HEAD of main):
    .\Test-NsinnounpBuild-Linux.ps1
    # Test a specific commit:
    .\Test-NsinnounpBuild-Linux.ps1 -Commit abc1234 -VerifyArtifact

 .SYNOPSIS
    Checks CI host drive free space and alerts via Windows Event Log (and optionally a webhook).
 .DESCRIPTION
    Intended to run as a scheduled task every 15 minutes (registered by
    Register-CIScheduledTasks.ps1). If the monitored drive is below MinFreeGB,
    writes a Warning entry to the Windows Application Event Log under source
    'CI-DiskAlert' (Event ID 1001) and exits with code 1 so Task Scheduler
    marks the task as failed (visible in Task Scheduler history).
    If WebhookUrl is provided, also POSTs a JSON payload to that URL
    (compatible with Discord and Gitea webhooks — content field only).
    A full drive silently causes vmrun clone to fail with cryptic errors
    (not enough disk space for linked clone delta files). Alert early.
 .PARAMETER MinFreeGB
    Alert threshold in GB. Default: 50
 .PARAMETER DriveLetter
    Single letter (no colon) of the drive to monitor. Default: F
 .PARAMETER WebhookUrl

 .SYNOPSIS
    Monitors the act_runner service and auto-restarts it if stopped.
 .DESCRIPTION
    Intended to run as a scheduled task every 15 minutes (registered by
    Register-CIScheduledTasks.ps1 as CI-RunnerHealth).
    Behaviour:
    - If act_runner is Running: exits 0, no action.
    - If not Running: writes a Warning to the Windows Application Event Log
      (source CI-RunnerHealth, EventId 1002), then attempts Restart-Service.
    - Restart attempts are rate-limited to MaxRestarts per hour using a JSON
      state file in StateDir. Once the limit is hit, further runs write an
      alert (EventId 1004) and exit 1 without restarting — Task Scheduler
      history shows the failure so the operator is alerted.
    - On successful restart: writes EventId 1003 (Information).
    - Optional WebhookUrl: POSTs a JSON payload compatible with Discord and
      Gitea webhooks on every restart or limit-exceeded event.
 .PARAMETER MaxRestarts
    Maximum number of auto-restart attempts allowed per rolling 60-minute
    window before giving up and requiring manual intervention. Default: 3
 .PARAMETER ServiceName
    Windows service name to monitor. Default: act_runner
 .PARAMETER StateDir
    Directory used for the cooldown state file (runner-restart-log.json).
    Default: F:\CI\State
 .PARAMETER WebhookUrl
    Optional Discord/Gitea webhook URL. If empty, only Event Log is written.

 .SYNOPSIS
    Returns a PSSessionOption for WinRM HTTPS with self-signed certificate.
 .DESCRIPTION
    All CI build VMs use a self-signed TLS cert on WinRM port 5986.
    This option set skips CA, CN, and revocation checks — appropriate for
    an isolated lab network where PKI is not present.

 #Requires -Version 5.1
 <#
 .SYNOPSIS
    Deploys an Ubuntu 24.04 LTS build VM on VMware Workstation using a cloud
    VMDK and a cloud-init seed ISO.
 .DESCRIPTION
    Host-side orchestrator. Produces a ready-to-use Linux template VM:
      Step 1  — Validate prerequisites + download cloud VMDK if not cached
      Step 2  — Generate cloud-init user-data + meta-data files
      Step 3  — Build cloud-init seed ISO (nocloud datasource, label: cidata)
      Step 4  — Copy and resize the cloud VMDK
      Step 5  — Generate the .vmx (EFI, SCSI disk, NAT vmxnet3, seed ISO)
      Step 6  — Power on the VM (vmrun start gui/nogui -- async)
      Step 7  — Detect guest IP via vmrun getGuestIPAddress (polls up to 5 min)
      Step 8  — Poll SSH port 22 until ready
      Step 9  — Verify cloud-init completed (boot-finished flag)
      Step 10 — Remove seed ISO from VMX (prevent re-run on clone)
      Final   — Print summary
    cloud-init nocloud datasource:
      Two files (user-data + meta-data) are written to a staging directory and
      burned into a small ISO labelled "cidata". On first boot, cloud-init reads
      both files and creates the $CloudUser account with the SSH public key.
      No packages are installed and no runcmd runs: all provisioning (apt,
      toolchain, SSH hardening, swap) is handled by Prepare-LinuxBuild2404.ps1
      via Setup-LinuxBuild2404.sh. Step 9 waits for
      /var/lib/cloud/instance/boot-finished before proceeding.
    NIC:
      vmxnet3 + NAT. Ubuntu 24.04 cloud images ship with open-vm-tools which
      provides the guest IP reporting used in Step 7.
    Disk:
      Official Ubuntu 24.04 Server cloud VMDK from cloud-images.ubuntu.com.
      Downloaded and cached to $VmdkCachePath on first run. Expanded to
      $DiskSizeGB GB in Step 4 using vmware-vdiskmanager.
 .PARAMETER VMXPath
    Full path of the .vmx file to create. The folder is created if missing.
 .PARAMETER VMName
    Display name in the Workstation library.
 .PARAMETER CloudUser
    Username for the cloud-init created account. Default: ci_build.
 .PARAMETER Hostname
    Guest hostname embedded in cloud-init meta-data and user-data.
 .PARAMETER Timezone
    IANA timezone string for the guest. Default: Europe/Rome.
 .PARAMETER DiskSizeGB
    Target disk size in GB after resize. Default: 40.
 .PARAMETER MemoryMB
    Guest RAM in MiB. Default: 4096.
 .PARAMETER VCPUCount
    Total vCPU count. Default: 4.
 .PARAMETER CoresPerSocket
    Cores per socket. Default: 2.
 .PARAMETER SnapshotName
    Snapshot name recorded in the summary. The snapshot itself is taken by
    Prepare-LinuxBuild2404.ps1.
 .PARAMETER VMwareWorkstationDir
    VMware Workstation install directory.
 .PARAMETER SshKeyPath
    Path to the SSH private key. The public key is inferred as SshKeyPath.pub.
 .PARAMETER VmdkUrl
    URL to download the Ubuntu 24.04 cloud VMDK.
 .PARAMETER VmdkCachePath
    Local cache path for the downloaded VMDK. Reused across runs.
 .PARAMETER SeedIsoPath
    Path for the cloud-init seed ISO. Default: <VMDir>\cloud-init-seed.iso.
 .PARAMETER SshTimeoutSeconds
    Total time in seconds to wait for SSH port 22 to become reachable. Default: 300.
 .PARAMETER SshPollIntervalSeconds
    Seconds between SSH port poll attempts. Default: 10.
 .PARAMETER ShowGui
    When set, vmrun powers on the VM with the Workstation GUI visible.
    Default: headless (nogui) for unattended pipelines.
 .PARAMETER Force
    Allow overwriting an existing VM directory. Without this switch, the script
    aborts if the VMX destination folder already exists.
 .PARAMETER DiagPassword
    If specified, adds a chpasswd block to cloud-init user-data that sets this
    plaintext password on the 'ubuntu' account. Allows console login for
    diagnostics. Do NOT use in production; remove or omit once the template
    is verified.
 .PARAMETER StartFromStep
    Skip straight to this step number. All derived paths are still computed;
    artifacts from skipped steps must already exist on disk.
    Steps: 1=prereqs+vmdk  2=cloud-init files  3=seed ISO  4=vmdk copy+resize
           5=VMX  6=power on  7=guest IP  8=SSH port  9=cloud-init verify
           10=detach seed ISO
 .NOTES
    Does not require elevation. Assumes the host has vmrun.exe and
    vmware-vdiskmanager.exe in the VMware Workstation directory, and ssh.exe
    in PATH (OpenSSH for Windows or Git for Windows).

 .SYNOPSIS
    HOST-side script: delivers and runs Setup-LinuxBuild2404.sh inside the Linux template VM.
 .DESCRIPTION
    Automates provisioning of the Ubuntu 24.04 template VM from the host machine via SSH/SCP:
      1. Pre-flight validation: ssh/scp in PATH, SSH key present, VMX exists (if supplied),
         IPv4 address valid, TCP/22 reachable
      2. Auto power-on + guest IP detection via vmrun getGuestIPAddress (when -VMXPath provided)
      3. Add host key to known_hosts (idempotent, uses StrictHostKeyChecking=accept-new)
      4. Copy Setup-LinuxBuild2404.sh to /tmp on guest via scp + validate file size
      5. Execute Setup-LinuxBuild2404.sh via SSH (stdout/stderr streamed to host console)
      6. Post-setup remote validation batch check (user, sudo, tools, CI dirs, swap, sshd)
      7. Graceful shutdown + vmrun snapshot (when -TakeSnapshot or -VMXPath provided)
      Final: print summary
    Every validation step uses Assert-Step: prints [OK] on success, throws on failure.
    The snapshot is only taken after this script exits 0.
    PREREQUISITES (do these manually before running this script):
      a. The VM was created by Deploy-LinuxBuild2404.ps1 and cloud-init has completed
      b. The ci_build SSH public key ($SshKeyPath.pub) is already authorised in the guest
         (cloud-init in Deploy-LinuxBuild2404.ps1 injects the public key automatically)
      c. The VM NIC is on VMnet8 (NAT) with internet access
    AFTER THIS SCRIPT COMPLETES (exit 0, all validations passed):
      If -TakeSnapshot was NOT set and -VMXPath was NOT provided:
        1. Shut down the VM manually
        2. Take a snapshot named '$SnapshotName' in VMware Workstation
        3. Use -SnapshotName '$SnapshotName' when calling New-BuildVM.ps1
 .PARAMETER VMXPath
    Full path to the template VM's .vmx file.
    When provided:
      - If the VM is powered off, the script starts it automatically via vmrun.
      - The guest IP is auto-detected via vmrun getGuestIPAddress (requires open-vm-tools).
      - At the end, the VM is shut down and a snapshot is taken automatically.
    Either -VMXPath or -VMIPAddress (or both) must be supplied.
 .PARAMETER VMIPAddress
    IP address of the template VM on VMnet8 NAT.
    Optional when -VMXPath is provided (IP is auto-detected via open-vm-tools).
    Required when -VMXPath is omitted.
    Example: 192.168.79.131
 .PARAMETER CloudUser
    SSH username in the guest VM. Default: ci_build.
 .PARAMETER SshKeyPath
    Path to the SSH private key on the host. Default: F:\CI\keys\ci_linux.
    The corresponding public key is expected at $SshKeyPath.pub.
 .PARAMETER SnapshotName
    Name of the snapshot to create. Default: BaseClean-Linux.
    Must match the snapshot name used in New-BuildVM.ps1.
 .PARAMETER SkipUpdate
    Pass --skip-update to Setup-LinuxBuild2404.sh (skips apt-get upgrade).
 .PARAMETER InstallDotNet
    Pass --dotnet to Setup-LinuxBuild2404.sh (installs .NET SDK).
 .PARAMETER NoMingw
    Pass --no-mingw to Setup-LinuxBuild2404.sh (skips MinGW cross-compiler).
    MinGW is installed by default; use this only to skip it.
 .PARAMETER TakeSnapshot
    Shut down the VM and take a vmrun snapshot after provisioning completes.
    Implied automatically when -VMXPath is provided (snapshot is always taken
    when the script manages the VM lifecycle via vmrun).
 .PARAMETER VMwareWorkstationDir
    Installation directory of VMware Workstation on the host.
    Default: C:\Program Files (x86)\VMware\VMware Workstation
 .EXAMPLE
    # Fully automated — VMX path only (power-on + IP detection + snapshot automatic):
    .\Prepare-LinuxBuild2404.ps1 -VMXPath 'F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx'
    # Explicit IP, skip update (VM already running, no snapshot):
    .\Prepare-LinuxBuild2404.ps1 -VMIPAddress '192.168.79.131' -SkipUpdate
    # VMX + .NET SDK + explicit snapshot:
    .\Prepare-LinuxBuild2404.ps1 `
        -VMXPath 'F:\CI\Templates\LinuxBuild2404\LinuxBuild2404.vmx' `
        -InstallDotNet -TakeSnapshot
 .NOTES
    Requires:
      - OpenSSH client on the host (ssh.exe + scp.exe in PATH)
      - VMware Workstation with vmrun.exe (only needed when -VMXPath is supplied)
      - open-vm-tools installed in the guest (for vmrun getGuestIPAddress)
      - The SSH private key at $SshKeyPath with correct permissions

      1. Pre-flight validation: script presence, IP octet range, TCP/5986 reachable
      2. Configures host WinRM client (TrustedHosts only, HTTPS needs no AllowUnencrypted) — restored on exit
      3. Validates host WinRM TrustedHosts applied correctly
      4. Opens PSSession -UseSSL -Port 5986 -SkipCACheck — fails fast with actionable message
         (PS 5.1 Test-WSMan has no -SessionOption, so PSSession is used as the connectivity probe)
      5. PSSession open — step 4 and 5 are now merged
      6. Ensures C:\CI exists on guest; validates creation
      7. Copies Setup-WinBuild2022.ps1 into the VM; validates file present + size match
      8. Runs Setup-WinBuild2022.ps1 inside the VM with the given parameters
         (Setup performs per-step validation internally — aborts on any failure)
      9. Handles the reboot-required case (exit 3010) and optionally re-runs
     10. Post-setup remote validation: 9 guest-state checks via a single Invoke-Command
         (WinRM, user+admin, UAC, firewall, .NET, Python, MSBuild, CI dirs)
     11. Restores host TrustedHosts in finally block
    Every validation step uses Assert-Step: prints [OK] on success, throws on failure.
    The snapshot should only be taken after this script exits 0.
    PREREQUISITES (do these manually before running this script):
      a. VM NIC is set to VMnet8 (NAT) — the VM needs internet for downloads
      b. Windows Server is installed and booted
      c. WinRM is enabled inside the VM. From an elevated cmd/PS in the VM run:
            winrm quickconfig -q
            Enable-PSRemoting -Force -SkipNetworkProfileCheck
      d. You know the IP address the VM got from DHCP on VMnet8 (NAT)
         (check via: ipconfig inside the VM, or VMware → VM → Settings →
          Network Adapter → Advanced → MAC address, then check DHCP leases)
    AFTER THIS SCRIPT COMPLETES (exit 0, all validations passed):
      1. Shut down the VM
      2. Take snapshot: VM → Snapshot → Take Snapshot → name: BaseClean
         (VM stays on VMnet8 NAT — internet access is required for builds)
      3. Store credentials on host (use the same password chosen during provisioning):
         New-StoredCredential -Target 'BuildVMGuest' -UserName 'ci_build' `
             -Password '<your-build-password>' -Persist LocalMachine
 .PARAMETER VMXPath
    Full path to the template VM's .vmx file (e.g. F:\CI\Templates\WinBuild\WinBuild.vmx).
    When provided:
      - If the VM is powered off, the script starts it automatically via vmrun.
      - The guest IP is detected automatically via vmrun getGuestIPAddress (requires
        VMware Tools installed in the guest).
      - At the end, the snapshot is created automatically after provisioning.
    Either -VMXPath or -VMIPAddress (or both) must be supplied.
 .PARAMETER VMIPAddress
    IP address of the template VM on VMnet8 NAT.
    Optional when -VMXPath is provided (IP is auto-detected via VMware Tools).
    Required when -VMXPath is omitted.
    Example: 192.168.79.130
 .PARAMETER AdminUsername
    Administrator username inside the VM. Default: Administrator
 .PARAMETER AdminPassword
    Administrator password inside the VM. If not supplied, prompts interactively.
 .PARAMETER BuildPassword
    Password to set for the ci_build user inside the VM.
    Must not be empty — script prompts interactively if not supplied.
 .PARAMETER BuildUsername
    Local username for the CI build account inside the VM. Default: ci_build.
    Passed through to Setup-WinBuild2022.ps1 and used in post-setup validation.
 .PARAMETER DotNetSdkVersion
    .NET SDK channel to install in the VM. Default: 10.0 (matches host SDK).
 .PARAMETER SkipWindowsUpdate
    Pass through to Setup-WinBuild2022.ps1 to skip the Windows Update step.
 .PARAMETER SnapshotName
    Name of the snapshot to create. Default: BaseClean (case-sensitive — used by New-BuildVM.ps1).
    Only relevant when -TakeSnapshot is set.
 .PARAMETER StoreCredential
    After provisioning completes, store BuildUsername/BuildPassword in Windows
    Credential Manager (target: CredentialTarget). Installs the CredentialManager
    module (CurrentUser scope) automatically if not present.
    Equivalent to running manually:
        New-StoredCredential -Target 'BuildVMGuest' -UserName 'ci_build' `
            -Password '<pwd>' -Persist LocalMachine
 .PARAMETER CredentialTarget
    Windows Credential Manager target name used when -StoreCredential is set.
    Default: BuildVMGuest (matches the target expected by Invoke-CIJob.ps1 and
    the other CI scripts that load guest credentials via Get-StoredCredential).
