What problem does it solve? Validating that a locally built Tillandsias tray actually installs and re-provisions a host runtime from scratch is error-prone manual work, and stale artifacts or leftover state can silently invalidate the test. This Skill runs a gated, OS-aware end-to-end smoke test that proves a local build can destroy and rebuild the host's runtime substrate. ## Core Features & Use Cases - OS-aware build and install: Detects Linux, macOS, or Windows and runs the matching build script (build.sh --ci-full --install, build-macos-tray.sh, or build-windows-tray.ps1) with freshness gates that verify the installed binary matches HEAD. - Destructive clean-room reset: Irreversibly wipes the runtime substrate (Podman store, Virtualization.framework VM directory, or WSL2 distro plus Credential Manager vault entries) so re-provisioning is tested from a truly pristine state. - Cold re-provision and forge lane: Re-provisions from nothing via tillandsias --init or tray --provision, and on Linux launches the meta-orchestration forge smoke. - Use Case: A maintainer on a Fedora smoke host runs this Skill after a change to the installer; it builds the tray, wipes Podman, re-initializes the stack, and files any failure as a plan/issues/ work packet with evidence logs. ## Quick Start Use the build-install-and-smoke-test-e2e skill to build and install the local Tillandsias tray on this host, reset its runtime substrate, re-provision from scratch, and file any issues you find.
