Verified the whole Azure signing path on the runner (.133) today and it failed twice, for two reasons that neither error message named. Both are now provisioned here so a rebuild from the unom/infra Packer template cannot silently un-fix them. Azure.CodeSigning.Dlib.dll is a mixed-mode C++/CLI assembly: it ships Ijwhost.dll and a runtimeconfig.json pinning Microsoft.NETCore.App 8.0.0. The runner had NO .NET runtime at all — pwsh 7 is a self-contained install and brings no shared runtime — so signtool exited 3 having printed absolutely nothing. Installing the .NET 8 runtime turned that into a clean sign. The client itself installs machine-wide under C:\trusted-signing rather than a user's .nuget, because act_runner runs as SYSTEM, whose USERPROFILE is C:\Windows\System32\config\systemprofile. A per-user install under Administrator is invisible to every job that actually builds. Confirmed by resolving Find-AzureDlib from a SYSTEM scheduled task, which is also how the earlier SSH-only attempts misled: over a network logon New-SelfSignedCertificate hits NTE_PERM, so a control test that "fails" there proves nothing about how CI will behave. Both downloads are SHA-256 pinned against version-immutable URLs (nuget.org flat-container and the dotnet builds CDN), so they fail closed on tampering rather than on every Microsoft patch release — unlike the BtbN `latest` pin above, which re-rolls. The .NET install uses Start-Process -Wait because the bundle is a GUI PE that returns instantly under `&`, leaving $LASTEXITCODE unset and racing the completion check (cost one false failure here). End-to-end result on .133, as SYSTEM: sign rc=0, verify rc=0, chain Microsoft Identity Verification Root CA 2020 -> ID Verified CS EOC CA 04 -> "unom - Enrico Buhler", leaf thumbprint DD6A610F242CB5B2078C2A5D628699B6AB0CAC07 (matches the profile Azure reports), timestamped, leaf expires in 3 days as expected. Signing an unsigned binary and reading the subject back reproduces pack-msix.ps1's Publisher assertion exactly (match=True) — checked against a NON-catalog-signed binary on purpose, because Get-AuthenticodeSignature on a catalog-signed system exe returns the catalog signer and would have read as a false mismatch.
