function Update-KadenRepo { <# .SYNOPSIS Apply the installed Kaden managed payload to an initialized child repository. .DESCRIPTION Validates the installed package, refuses to proceed when another update holds the lock or an incomplete transaction remains, then applies allowlisted managed files under a child-root journal. Child-owned overlays outside the managed-file manifest are preserved. Unknown keys already present in `.kaden.json` survive the version-state write. Invalid JSON in the shared manifest is refused before any managed file changes, with instructions to repair or restore it. A failure to read the file is left as that read error. .EXAMPLE Update-KadenRepo -Path . #> [CmdletBinding(SupportsShouldProcess = $true)] param( [Parameter(Mandatory = $true)] [string]$Path ) $childRoot = [System.IO.Path]::GetFullPath($Path) if (-not (Test-Path -LiteralPath $childRoot)) { throw "KDN-TXN-PREFLIGHT-FAILED: Child repository path does not exist: $childRoot" } if (-not $PSCmdlet.ShouldProcess($childRoot, 'Update-KadenRepo')) { return } $sharedPath = Join-Path $childRoot '.kaden.json' if (-not (Test-Path -LiteralPath $sharedPath)) { throw 'KDN-TXN-PREFLIGHT-FAILED: Child repository is not initialized (.kaden.json missing).
