• Model sizes now come from the asset service's inventory. On some Macs, including macOS 27.0.1, the per-set status reported 0 for installed models, so off removed nothing. Diagnosed by Vlad Tulitu in #2.
• When off removes models, it also asks the asset service to remove sets whose asset folders still hold files.
• Releases are built from their tag by GitHub Actions and carry a build provenance attestation.
