+## S19 review follow-up — 2026-11-10
+
+- Skills relocated unchanged to landscape/skills/ with upstream revision records,
+  attribution and licenses. New consumers reference landscape workflows.
+- Eight bootstrap/generator tests passed, including actual Maven bootstrap with
+  generated/ absent, all component selections and the CLI's default mini-pc label.
+- Twenty-one CI tests passed, including shared runner scope/identity and preflight
+  rejection of missing, offline or differently labelled runners.
+- Thirty-four release behavior tests passed against the actual remote shell.
+- Formatter integration passed; changed Java helpers formatted with the pinned engine.
+- User-scoped mini-pc runner registered and online; repository-level API runner
+  listings exclude inherited user runners, so preflight checks the selected scope
+  and verifies that the repository owner matches for user scope.
+
+Consumer builds and actual remote workflow results are recorded in the consuming
+repositories. No production deployment is part of this follow-up.
