+## Automated contract
+
+The scaffold matrix in `tools/loop-init/test/cli.test.mjs` runs every supported
+pattern × tool combination in a fresh temporary directory. It verifies the
+state, observability, constraints, primary skill, and tool-specific files, plus
+the presence or absence of circuit-breaker and intake assets where required.
+
+\`\`\`
+cd tools/loop-init
+npm test
+\`\`\`
+
+The automated matrix guards the scaffold contract on every PR. The table below
+remains the place for manual UX checks such as the printed Loop Ready score,
+platform-specific behavior, and unexpected output.
