+## Dead-code candidates
+
+Use `FmxSQLDeadCodeRule openOn: routines` to open the standard Dead Code browser
+with the SQL refuting rule selected, or select that rule explicitly in an existing
+browser before computing. SQL routines are externally callable, so this SQL preset
+protects all of them until a closed-world candidate set is explicitly supplied.
+The generic OO preset alone is not a SQL dead-code analysis.
+Trigger/constraint bindings and missing or incomplete analysis remain protected.
+For an explicitly bounded analysis, configure its selected `FmxSQLDeadCodeRule`:
+
+```smalltalk
+rule closedWorldCandidates: knownClosedWorldRoutines.
+rule externalEntryPoints: knownExternalRoots.
+```
+
+The remaining results are candidates, not proof that routines can be dropped.
+This integration does not execute database DDL or remove definitions. Existing
+non-SQL dead-code rules retain their behavior.
