Package build is the domain core of incusos-builder: it resolves a release from update-server metadata, probes the acquired image's GPT, renders and splices the seed tar, and orchestrates offline rescue-media construction — all through ports, with no direct network or filesystem side effects.

Package cli is the incusos-builder command-line surface: the Cobra root, interaction policy, sentinel-to-exit-code mapping, and the output publisher.

Package config loads an incusos-builder YAML document into a build.Spec.

Package errdefs holds the sentinel errors shared across the domain core and the adapters.

Package media implements build.RescueWriter with go-diskfs: iso9660 (Rock Ridge, no Joliet) and GPT+FAT32 raw media labeled RESCUE_DATA.

Package seed renders the IncusOS seed-data tar byte-compatibly with upstream image-customizer writeSeed.

Package testfixture writes a local-dir update-server mirror for e2e tests.

Package update is the ImageSource adapter: an HTTPS update-server client and a local-directory source, both exposing verified content-addressed assets through the build.ImageSource port.

Package ux implements the build.Reporter port with a fancy Lip Gloss renderer and a plain ASCII renderer behind one constructor.
