What problem does it solve? Running the daily build-and-install loop for the Tillandsias Windows tray binary requires many error-prone manual steps on the actual Windows host, including staging the embedded Linux guest binary, handling PowerShell quirks, and verifying the install with --diagnose. This Skill codifies the exact known-working workflow so it runs consistently on every daily iteration. ## Core Features & Use Cases - Deterministic build pipeline: Syncs the windows-next branch, stages the embedded Linux guest binary, and runs the release build via scripts/build-windows-tray.ps1 or direct cargo invocation. - Safe install and verification: Stops the running tray, installs to %LOCALAPPDATA%\Programs\Tillandsias, and runs the --diagnose --json post-install check with exit-code interpretation (0 healthy, 2 degraded, 1 failure). - Cross-host findings ledger: Appends structured per-run sections to plan/issues/windows-build-findings-YYYY-MM-DD.md so sibling hosts can grep SECTION_KIND to see whether the Windows build is green. - Use Case: A scheduled daily loop fires on the Windows host, fast-forwards the branch, rebuilds the tray with a freshly staged guest binary, installs it, verifies the 16-key diagnose schema, and commits a findings report flagging any regression. ## Quick Start Run the build-windows-tray workflow to sync the windows-next branch, build and install the tray binary, verify it with --diagnose, and record today's findings file.
