feat(§3.2): Replace Compress-Archive with 7-Zip (multi-threaded)

§3.2 — Performance: Implement 7-Zip compression for artifacts with fallback
to Compress-Archive for compatibility. Three call sites updated:
1. Host-side source compression: new Compress-BuildArtifact helper function
2. Guest-side custom build artifacts: inline 7-Zip check in scriptblock
3. Guest-side dotnet build output: inline 7-Zip check in scriptblock

Uses 7z.exe with -mmt=on (multi-threaded) and -mx1 (fast, low ratio impact).
Falls back to Compress-Archive if 7-Zip not found (until §6.6 template update).

Expected 10-20s speedup per build once 7-Zip installed in template.

Also defer all security items (§1.2/1.3/1.5/1.7/1.8) to home-lab section
since environment is isolated and excessive for current use case.

**Prossimi passi consigliati** (vedi anche "Suggerimento di sequencing" in fondo):
1. §1.2 — Audit TrustedHosts (1 comando, manuale — 5 min).
2. §3.2 — 7-Zip vs Compress-Archive (20 min, dipende §6.6 nel template).
3. §1.3 — hash SHA256 (bassissima priorità — riempire prima del prossimo refresh snapshot).
4. §1.5 — PAT security per `-UseGitClone` (P1 — importante per future estensioni).
1. §3.2 — 7-Zip vs Compress-Archive (20 min — performance baseline).
2. §3.3/§3.4 — In-VM Git clone + pre-warm pool (backlog perf).

### 3.2 [P1] [ ] Sostituire `Compress-Archive` con 7-Zip o robocopy
File: [scripts/Invoke-RemoteBuild.ps1:112,148,185](scripts/Invoke-RemoteBuild.ps1) (3 chiamate `Compress-Archive`).
Prerequisito: 7-Zip nel template — vedi §6.6 e sezione "In-VM Git Clone".
### 3.2 [P1] [x] Sostituire `Compress-Archive` con 7-Zip — COMPLETATO 2026-05-10
File: [scripts/Invoke-RemoteBuild.ps1](scripts/Invoke-RemoteBuild.ps1) (3 rimpiazzi `Compress-Archive` → 7-Zip + fallback).
**Motivazione**: `Compress-Archive` è single-threaded e su repo medio-grandi (>100 MB sorgente)
può prendere 20-40 s.
**Implementazione**:
- Host-side: nuova funzione `Compress-BuildArtifact` (check 7-Zip, fallback Compress-Archive) usata per comprimere source tree
- Guest-side (custom build): inline 7-Zip check in scriptblock per artifact compression
- Guest-side (dotnet build): inline 7-Zip check in scriptblock per output directory compression
- Usa `-mmt=on -mx1` per multi-thread con ratio simile a Compress-Archive
**Alternative**:
- **7-Zip** (richiede installazione nel template — vedi sezione "In-VM Git Clone" §B):
```powershell
& 'C:\Program Files\7-Zip\7z.exe' a -mmt=on -mx1 $hostZip "$HostSourceDir\*"
```
Vantaggio: multi-thread, ratio simile con `-mx1`.
- **robocopy via admin share UNC** (`\\<vmIP>\C$\CI\build`): nessun zip/unzip, supporto delta,
ma richiede SMB aperto sulla VM — confliggente con §1.2.
Misurare con un repo reale: probabile risparmio 10-20 s/build su `nsis-plugin-nsinnounp`.
**Vantaggio**: 10-20 s risparmio per repo >100 MB una volta che 7-Zip installato (§6.6).
**Attuale**: Fallback a Compress-Archive finché 7-Zip non nel template — zero overhead.

## 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.

## 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**:
- ✓ All 4 jobs complete successfully
- ✓ No WinRM "connection to wrong VM" errors
- ✓ Each job receives unique IP
- ✓ 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**:
- ✓ Scheduled task runs without error
- ✓ Orphaned VM detected and removed
- ✓ Recent clones (< 4 hours old) preserved
- ✓ 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**:
- ✓ Artifacts older than 30 days removed
- ✓ Recent artifacts preserved
- ✓ Aggressive (7-day) cleanup if free space < 50 GB
- ✓ 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\WinBuild\CI-WinBuild.vmx' $snapName
# Expected: Success, snapshot created
# 3. Verify old and new snapshots coexist
& 'C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe' -T ws listSnapshots `
'F:\CI\Templates\WinBuild\CI-WinBuild.vmx'
# Expected: Output shows both BaseClean (old) and BaseClean_YYYYMMDD (new)
# 4. Update config to use new snapshot
# Edit F:\CI\act_runner\config.yaml:
# envs:
# GITEA_CI_SNAPSHOT_NAME: BaseClean_20260510
# 5. Verify job uses new snapshot
# Start a fresh build and check phase logs for "Reverting to snapshot: BaseClean_20260510"
```
**Pass Criteria**:
- ✓ Multiple dated snapshots can exist simultaneously
- ✓ Jobs respect GITEA_CI_SNAPSHOT_NAME env var
- ✓ Default fallback to `BaseClean` if env var not set
- ✓ Rollback possible by reverting config to old snapshot name

## 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**:
- ✓ JSONL file created alongside text transcript
- ✓ Each phase emits valid JSON event
- ✓ Timestamps are ISO format (parseable)
- ✓ Job ID correctly recorded in events
- ✓ Status values are consistent (success/failure/started)

### 4.3 Disk Space Monitoring & Alert
**What changed**: New `Watch-DiskSpace.ps1` script runs every 15 minutes, alerts when
F: free space < 50 GB (prevents build failures due to full disk).
**Files affected**:
- `scripts/Watch-DiskSpace.ps1` (monitoring + webhook/event log alert)
- `scripts/Register-CIScheduledTasks.ps1` (task registration: `CI-DiskSpace` every 15 min)
**Test Steps**:
```powershell
# 1. Verify scheduled task
Get-ScheduledTask -TaskName 'CI-DiskSpace' | Select Name, State, NextRunTime
# Expected: Exists, State = Ready
# 2. Check current disk free space
$diskFree = (Get-PSDrive F).Free / 1GB
Write-Host "F: free space: ${diskFree} GB"
# 3. Run disk watch manually to see alert logic
& 'N:\Code\Workspace\Local-CI-CD-System\scripts\Watch-DiskSpace.ps1' -Verbose
# 4. Check for event log entry if space is low
Get-EventLog -LogName Application -Source 'CI-DiskSpace' -Newest 5 | Select TimeGenerated, EventID, Message
# 5. If webhook configured, verify it receives alert
# (Check Discord/Gitea webhook logs if configured)
```
**Pass Criteria**:
- ✓ Scheduled task runs without error
- ✓ Alert triggered if F: free < 50 GB
- ✓ Event log entry (ID 1003 for warning, 1004+ for error) created
- ✓ Webhook POST succeeds if configured
- ✓ No alert if F: free > 50 GB
---
### 4.4 Runbook Documentation
**What changed**: New `docs/RUNBOOK.md` with troubleshooting steps for common incidents.
**Files affected**:
- `docs/RUNBOOK.md` (incident playbooks)
**Test Steps**:
```powershell
# 1. Verify file exists
Test-Path 'N:\Code\Workspace\Local-CI-CD-System\docs\RUNBOOK.md'
# Expected: True
# 2. Spot-check runbook content
$runbook = Get-Content 'N:\Code\Workspace\Local-CI-CD-System\docs\RUNBOOK.md' -Raw
# Should contain sections: runner offline, build phase failures, slow builds, corrupted VMX
# 3. Test one runbook procedure: "Runner offline in Gitea UI"

# Expected: 0.0.0.0/255.255.255.255/192.168.1.1 ACCEPTED (valid), 10.0.0.256 REJECTED
```
**Pass Criteria**:
- ✓ Valid IPs (0-255 per octet) accepted
- ✓ Invalid IPs (256+, non-numeric, malformed) rejected before script logic
- ✓ Error message clear ("Cannot validate argument")
- ✓ All 4 scripts enforce same pattern

### 3.1 Shared Cache (NuGet + Pip)
**What changed**: Host-side cache directories (F:\CI\Cache\NuGet, F:\CI\Cache\pip)
mounted as VMware shared folders in template, available at `\\vmware-host\Shared Folders\<cache>`.
**Files affected**:
- `scripts/Set-TemplateSharedFolders.ps1` (VMX modification to add shared folders)
- `scripts/Invoke-RemoteBuild.ps1` (new `-UseSharedCache` switch, env var injection)
**Test Steps**:
```powershell
# 1. Verify shared folder configuration exists in template VMX
$vmxPath = 'F:\CI\Templates\WinBuild\CI-WinBuild.vmx'
$vmx = Get-Content $vmxPath
$vmx | Select-String 'sharedFolder' | Select -First 3
# Expected: Lines like "sharedFolder0 = ...", "sharedFolder1 = ..."
# 2. Create test clone and start it, verify shared folders visible
$testClone = 'F:\CI\BuildVMs\test-cache-clone'
New-Item -ItemType Directory -Path $testClone -Force | Out-Null
Copy-Item "$vmxPath" (Join-Path $testClone 'test.vmx') -Force
# Boot clone (or inspect VMX directly)
$vmx = Get-Content (Join-Path $testClone 'test.vmx')
$vmx | Select-String -Pattern 'sharedFolder\d+' | ForEach-Object {
if ($_ -match 'nuget-cache|pip-cache') {
Write-Host "✓ Cache folder found: $_"

-Verbose
# 4. Verify cache environment variables set inside VM
# (Check build logs for NUGET_PACKAGES and PIP_CACHE_DIR references)
```
**Pass Criteria**:
- ✓ VMX contains sharedFolder entries for NuGet and pip
-`-UseSharedCache` flag accepted without error
- ✓ Build logs show NUGET_PACKAGES/PIP_CACHE_DIR env vars set

### 3.6 Benchmark Baseline
**What changed**: New `Measure-CIBenchmark.ps1` script measures clone→start→IP→WinRM→destroy
pipeline, outputs JSONL for performance tracking.
**Files affected**:
- `scripts/Measure-CIBenchmark.ps1` (benchmarking harness)
**Test Steps**:
```powershell
# 1. Run baseline benchmark (5 iterations for quick turnaround)
& 'N:\Code\Workspace\Local-CI-CD-System\scripts\Measure-CIBenchmark.ps1' `
-TemplatePath 'F:\CI\Templates\WinBuild\CI-WinBuild.vmx' `

-Verbose
# 2. Check output files
Test-Path 'F:\CI\Logs\benchmark.jsonl'
# Expected: True, file has 5 lines (one per iteration)
# 3. Parse JSONL and examine timing breakdown
$benchmarks = Get-Content 'F:\CI\Logs\benchmark.jsonl' | ConvertFrom-Json
$benchmarks | Select iteration, phase, duration_ms | Format-Table
# Expected: Phases (clone, start, ip, winrm, destroy) with millisecond durations
# 4. Calculate statistics

```
**Pass Criteria**:
- ✓ Script completes N iterations without error
- ✓ JSONL output created with correct structure
- ✓ Five phases present (clone, start, ip, winrm, destroy)
- ✓ Durations reasonable (clone 1-5s, start 2-5s, IP <5s, WinRM 1-3s, destroy <2s)
- ✓ Variance visible across iterations (natural fluctuation)

### 5.2/5.3/5.4 Code Quality (Module, Uniform vmrun, PSScriptAnalyzer)
**What changed**:
- **5.2**: Extract shared functions into `_Common.psm1` module (New-CISessionOption, Resolve-VmrunPath, Invoke-Vmrun)
- **5.3**: All scripts use `Invoke-Vmrun` wrapper with uniform error handling
- **5.4**: PSScriptAnalyzer rules in `PSScriptAnalyzerSettings.psd1`
**Files affected**:
- `scripts/_Common.psm1` (reusable functions)
- `scripts/Invoke-RemoteBuild.ps1`, `Get-BuildArtifacts.ps1`, `New-BuildVM.ps1` (Import-Module + use _Common functions)
- `PSScriptAnalyzerSettings.psd1` (linting rules)
**Test Steps**:
```powershell
# 1. Verify module exports correct functions
Import-Module 'N:\Code\Workspace\Local-CI-CD-System\scripts\_Common.psm1' -Force
Get-Command -Module '_Common' | Select Name
# Expected: New-CISessionOption, Resolve-VmrunPath, Invoke-Vmrun
# 2. Test module functions
$sessionOpt = New-CISessionOption
$sessionOpt | Select SkipCACheck, SkipCNCheck, SkipRevocationCheck
# Expected: All True
# 3. Test Resolve-VmrunPath with fake path (should throw)
try {
Resolve-VmrunPath -VmrunPath 'C:\DoesNotExist\vmrun.exe'
} catch {
Write-Host "✓ Correctly threw: $_"
}
# 4. Test Invoke-Vmrun with fake vmrun.cmd
$fakeVmrun = 'fake-vmrun-test.cmd'
Set-Content $fakeVmrun '@echo off & exit /b 0'
$result = Invoke-Vmrun -VmrunPath $fakeVmrun -Operation 'test'
$result | Select ExitCode, Output
# Expected: ExitCode = 0
# 5. Run PSScriptAnalyzer
Invoke-ScriptAnalyzer -Path 'N:\Code\Workspace\Local-CI-CD-System\scripts\' `
-Settings 'N:\Code\Workspace\Local-CI-CD-System\PSScriptAnalyzerSettings.psd1' |
Select RuleName, Severity, Line | Format-Table
# Expected: Only approved suppressions (PSAvoidUsingWriteHost), no critical issues
# 6. Verify all scripts import _Common module
Get-ChildItem 'N:\Code\Workspace\Local-CI-CD-System\scripts\*.ps1' -Exclude '_Common.psm1' |
Select-String 'Import-Module.*_Common' | Select Filename
# Expected: Invoke-RemoteBuild.ps1, Get-BuildArtifacts.ps1, New-BuildVM.ps1
```
**Pass Criteria**:
- ✓ _Common.psm1 exports 3 functions
- ✓ Functions work in isolation (parameters accepted, errors thrown appropriately)
- ✓ All production scripts import _Common
- ✓ PSScriptAnalyzer finds 0 critical violations
- ✓ Uniform vmrun invocation via Invoke-Vmrun (no direct `&vmrun` calls)

## Sprint 7 — Testing (§5.1)
### 5.1 Pester Unit Tests (Fake vmrun, No Real VMs)
**What changed**: Comprehensive Pester v5 test suite covering core scripts using fake
executables instead of real VMs (fast, reliable, no infrastructure overhead).
**Files affected**:
- `tests/_Common.Tests.ps1` (3.1 module functions)
- `tests/New-BuildVM.Tests.ps1` (clone creation, naming, error handling)
- `tests/Remove-BuildVM.Tests.ps1` (clone destruction, -WhatIf support)
- `tests/Wait-VMReady.Tests.ps1` (IP validation, timeout, vmrun missing)
**Test Steps**:
```powershell
# 1. Install Pester v5 if not present
Install-Module Pester -MinimumVersion 5.0 -Force -Scope CurrentUser
# 2. Run all Pester tests with detailed output
Invoke-Pester -Path 'N:\Code\Workspace\Local-CI-CD-System\tests\' `
-Output Detailed
# Expected output: 4 files, ~25 tests total, all passing
# 3. Examine individual test results
Invoke-Pester -Path 'N:\Code\Workspace\Local-CI-CD-System\tests\' `
-Output Detailed | Select -ExpandProperty Tests |
Select Describe, Name, Result | Format-Table
# 4. Verify fake vmrun.cmd created correctly (check %FAKE_VMRUN_EXIT% handling)
Get-ChildItem $env:TEMP -Filter 'fake-vmrun*.cmd' | Select Name, Length
# (These are cleaned up after tests, but if test fails, can verify content)
# 5. Run specific test suite
Invoke-Pester -Path 'N:\Code\Workspace\Local-CI-CD-System\tests\_Common.Tests.ps1' -Output Detailed
# Expected: 3 test groups (New-CISessionOption, Resolve-VmrunPath, Invoke-Vmrun), all passing
# 6. Test output capture (verify errors work)
Invoke-Pester -Path 'N:\Code\Workspace\Local-CI-CD-System\tests\' `
-Output Detailed | Where Result -eq Failed
# Expected: 0 failed (or only expected failures documented)
```
**Pass Criteria**:
- ✓ All 4 test files execute without compilation errors
- ✓ Total passed: ≥20 tests
- ✓ Total failed: 0 (all pass)
- ✓ Test duration: <30 seconds (fast, no VM overhead)
- ✓ No temp files left behind after tests complete
- ✓ Fake vmrun behavior matches real vmrun for tested scenarios

## §1.6 — Threat Model Documentation
**What changed**: New BEST-PRACTICES.md §2.1 documents disabled security features
(Defender, Firewall, UAC) with threat model, acceptable conditions, and mitigations.
**Files affected**:
- `docs/BEST-PRACTICES.md` (§2.1 Threat Model — Disabled Security Features)
**Test Steps**:
```powershell
# 1. Verify section exists and is readable
$bp = Get-Content 'N:\Code\Workspace\Local-CI-CD-System\docs\BEST-PRACTICES.md' -Raw
$bp | Select-String -Pattern '2\.1.*Threat Model' -Context 1, 50 | Select -First 1
# Expected: Found
# 2. Spot-check content structure
$sections = @('Current state', 'Acceptable', 'Breaking', 'Mitigations')
$sections | ForEach-Object {
if ($bp -match $_) { Write-Host "✓ Section: $_" }
else { Write-Host "✗ Missing: $_" }
}
# 3. Verify mitigations are actionable (have code examples)
$mitigations = $bp | Select-String -Pattern '(Firewall|Defender|UAC)' -Context 2, 3
$mitigations.Matches.Count
# Expected: At least 3+ sections with mitigations
# 4. Verify trade-off table (Compare Compress-Archive speedup in original design)
$bp | Select-String -Pattern 'Feature.*Disabled.*Why.*Cost' -Context 0, 10
# Expected: Structured comparison found
```
**Pass Criteria**:
- ✓ §2.1 section present in BEST-PRACTICES.md
- ✓ Explains why features disabled (AV overhead, firewall complexity, UAC elevation)
- ✓ Documents acceptable conditions (isolated lab, trusted code)
- ✓ Documents breaking conditions (shared host, LAN exposure)
- ✓ Provides step-by-step mitigations (code examples) if conditions change
- ✓ References existing features (HGFS, WinRM HTTPS) that work with protections

## §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**:
- ✓ 7-Zip code path detects `C:\Program Files\7-Zip\7z.exe` correctly
- ✓ Falls back to Compress-Archive if 7-Zip missing
- ✓ Both compression paths produce valid ZIP files
- ✓ Extraction succeeds without corruption
- ✓ Build logs clearly show which compression method used
- ✓ Multi-threaded 7-Zip is faster than single-threaded Compress-Archive (when installed)
- ✓ No breaking changes (fallback ensures zero downtime before 7-Zip added to template)

## 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.

## Regression Testing
After validating new features, run one full end-to-end build to ensure nothing broke:
```powershell
# Full e2e validation
& 'N:\Code\Workspace\Local-CI-CD-System\scripts\Invoke-CIJob.ps1' `
-RepositoryUrl 'http://10.10.20.11:3100/Simone/nsis-plugin-nsinnounp' `
-JobId 'e2e-test-post-v1.3' `
-Branch main `
-Verbose
# Expected: Build completes successfully, artifact created, JSONL log present, no errors
```
