📝 WalkthroughWalkthroughThe portable launch workflow now uses systemd drop-ins for CPU delegation, validates Podman and nested BuildKit operation, records runtime state, and performs guarded cleanup with conditional restoration. Tests verify provisioning, BuildKit, and cleanup behavior. ChangesPortable profile workflow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The workflow’s cleanup can currently fail even when fixture contents are unchanged, and an earlier removal error can skip restoration of runner state; this may leave hosted runners altered and cause the CI job to fail, so the PR needs follow-up before merge.

<!-- markdownlint-disable MD041 --> ## Summary Portable launch now gives the real current-user Podman service a temporary `containers.conf` that selects systemd cgroups before the socket starts. Cleanup now compares every owned fixture file with its terminal newline, so unchanged drop-ins are removed. ## Changes - Configure the Portable Podman CLI and user-systemd service with the same temporary `containers.conf`. - Fail before nested BuildKit with an observed-value diagnostic unless Podman reports `CgroupManager=systemd`. - Preserve terminal newlines in cleanup comparisons for the CPU drop-ins and the new Podman fixture files. - Extend the Portable workflow contract test for configuration order, diagnostics, and cleanup ownership.

Portable launch used a process shim for
systemctl, so its rootless Podman API ran without the systemd CPU delegation required by nested BuildKit. This change prepares the accepted current-user delegation fixture, proves a nesteddocker-containerBuildx build through the exact Podman socket before onboarding, and restores runner state duringalways()cleanup.Changes
