#Requires -Version 5.1 Set-StrictMode -Version Latest $ErrorActionPreference = 'Stop' <# .SYNOPSIS Trusted adapter that derives AI check evidence for Invoke-RepositoryQualityDecision. .DESCRIPTION Builds agent-skill-behavior and ai-surface-sync evidence from a real changed-path set, an explicit path policy, a canonical/generated surface pair, and a deterministic eval runner result. The decision port does not attest these fields; this adapter does. It never invents AdapterAttested without deriving CurrentTargetSet from ChangedPaths. #> function Test-AiSurfacePath { param([string]$Path) if ([string]::IsNullOrWhiteSpace($Path)) { return $false } $normalized = $Path.Replace('\', '/') while ($normalized.StartsWith('./')) { $normalized = $normalized.Substring(2) } return ( $normalized.StartsWith('.github/', [System.StringComparison]::OrdinalIgnoreCase) -or $normalized.StartsWith('.cursor/', [System.StringComparison]::OrdinalIgnoreCase) ) } function Test-BehaviorBearingAiPath { param([string]$Path) if (-not (Test-AiSurfacePath -Path $Path)) { return $false } $normalized = $Path.Replace('\', '/').ToLowerInvariant() foreach ($token in @( '/agents/', '/skills/', '/prompts/', '/commands/', '/rules/', '.agent.md', 'skill.md', '.prompt.md' )) { if ($normalized.Contains($token)) { return $true } } return $false } function Get-AiChangedTargetSet { param([string[]]$ChangedPaths) $targets = [System.Collections.Generic.List[string]]::new() foreach ($path in @($ChangedPaths)) { $text = [string]$path if ([string]::IsNullOrWhiteSpace($text)) { continue } if (-not (Test-AiSurfacePath -Path $text)) { continue } $normalized = $text.Replace('\', '/') while ($normalized.StartsWith('./')) { $normalized = $normalized.Substring(2) } if (-not ($targets -contains $normalized)) { [void]$targets.Add($normalized) } } return @($targets.ToArray()) } function Get-AiBehaviorClassification { param([string[]]$TargetSet) $anyBehavior = $false $anySurface = $false foreach ($path in @($TargetSet)) { if (Test-BehaviorBearingAiPath -Path $path) { $anyBehavior = $true } if (Test-AiSurfacePath -Path $path) { $anySurface = $true } } if (-not $anySurface) { return $null } if ($anyBehavior) { return 'behavior-bearing' } return 'non-behavior-bearing' } function Test-AiSurfacesSynchronized { param( [string]$CanonicalContent, [string]$GeneratedContent ) if ($null -eq $CanonicalContent -or $null -eq $GeneratedContent) { return $false } return [string]::Equals( [string]$CanonicalContent, [string]$GeneratedContent, [System.StringComparison]::Ordinal ) } function New-RepositoryAiCheckEvidence { <# .SYNOPSIS Derive one AI check evidence hashtable from changed paths and runner/pair inputs. #> [CmdletBinding()] [Diagnostics.CodeAnalysis.SuppressMessageAttribute( 'PSUseShouldProcessForStateChangingFunctions', '', Justification = 'Builds an in-memory evidence hashtable for the decision port;
