Your task is to convert a single Xtend (.xtend) file into idiomatic Java (.java) targeting Java 21.

The output must: +- Be valid Java 21 code +- Compile without errors in the context of the dsl-devkit project +- Preserve all original functionality exactly +- Be idiomatic Java (NOT a mechanical translation) +- Include all necessary imports + +--- + +## DECISIONS + +- **Target: Java 21** (pattern matching, switch expressions, text blocks, records) +- **Template strategy: `StringBuilder`** (pure Java, no Xtend runtime dependency) +- **No `var` keyword**: Always use explicit types (no Java 10 `var` / `final var`) + - `val catalog = ...` -> `final CheckCatalog catalog = ...;` (NOT `final var catalog = ...;`) + - `var skip = ...` -> `int skip = ...;` (NOT `var skip = ...;`) + - All local variables, fields, and parameters must have explicit type declarations. + +--- + +## CONVERSION RULES + +Apply these rules systematically, in order. Every rule is mandatory. + +### 1. FILE STRUCTURE AND BASICS + +1.1. **Package declaration**: Keep identical. Add semicolon if missing. + +1.2. **Imports**: Convert all Xtend imports to Java imports. +- `import com.foo.Bar` stays as `import com.foo.Bar;` +- `import static com.foo.Bar.*` stays as `import static com.foo.Bar.*;` +- `import static extension com.foo.Bar.*` becomes `import static com.foo.Bar.*;` (the `extension` keyword is dropped; see Rule 8 for call-site conversion) +- Remove imports for Xtend-specific types that are no longer needed (e.g., `org.eclipse.xtend2.lib.StringConcatenation` if you use StringBuilder instead) +- Add any new imports needed by the Java code (e.g., `java.util.List`, `java.util.ArrayList`, `java.util.stream.*`, `java.util.Objects`) +- Do NOT add wildcard imports. Use explicit imports. +- Remove unused imports. + +1.3. **Class declaration**: +- Xtend classes are `public` by default. Add `public` explicitly. +- `class Foo extends Bar` becomes `public class Foo extends Bar` +- Xtend `interface` stays as `interface` (already public by default in Java too). +- Add `{` and `}` braces as normal Java. + +1.4. **Semicolons**: Add semicolons to all statements. Xtend allows omitting them; Java requires them. + +### 2. VARIABLE DECLARATIONS + +2.1. **`val` (final local variable)**: +- Always use explicit types: `final ExplicitType name = expr;` +- Example: `val catalog = EcoreUtil2.getContainerOfType(context, CheckCatalog.class)` becomes `final CheckCatalog catalog = EcoreUtil2.getContainerOfType(context, CheckCatalog.class);` + +2.2. **`var` (mutable local variable)**: +- Always use explicit types: `ExplicitType name = expr;` +- Example: `var skip = instance - 1` becomes `int skip = instance - 1;` + +2.3. **`val` fields (class-level final fields)**: +- `val String FOO = "bar"` becomes `private final String FOO = "bar";` +- `val static Logger LOGGER = ...` becomes `private static final Logger LOGGER = ...;` +- Always add explicit visibility (`private` unless a different visibility is needed). + +2.4. **`var` fields (class-level mutable fields)**: +- `var String name` becomes `private String name;` +- Add explicit visibility. + +### 3. METHOD DECLARATIONS + +3.1. **`def` methods**: +- `def` means `public` by default. Add explicit `public`. +- `def private`, `def protected`, `def package` keep their visibility. +- Add explicit return type. If the Xtend method omits the return type, infer it from the method body. +- Example: `def outputPath()` with body `'.settings'` becomes `public String outputPath()` + +3.2. **`override` keyword**: +- Replace `override` with `@Override` annotation plus the appropriate visibility modifier. +- `override void doGenerate(...)` becomes: + ```java + @Override + public void doGenerate(...) { + ``` +- `override protected doGenerate()` becomes: + ```java + @Override + protected void doGenerate() { + ``` + +3.3. **Return types and implicit returns**: +- Xtend methods return the value of the last expression. In Java, add explicit `return` statements. +- If a method's last expression is a value, wrap it in `return`. +- For `void` methods, no return is needed. +- Example: Xtend `def foo() { bar }` becomes Java `public SomeType foo() { return bar; }` + +3.4. **Method parameters**: +- Add `final` to parameters in methods that do not reassign them (follow the convention of the existing Java code in the project). +- `extension` parameters: see Rule 8. + +### 4. TYPE REFERENCES + +4.1. **`typeof(X)` to `X.class`**: +- Replace all `typeof(ClassName)` with `ClassName.class`. +- Example: `typeof(CheckCatalog)` becomes `CheckCatalog.class` + +4.2. **Generic type syntax**: Xtend and Java use the same generic syntax. Keep as-is. + +4.3. **Type casting**: `expr as Type` becomes `(Type) expr` or use pattern matching with `instanceof` (Java 21). + +### 5. OPERATORS AND EXPRESSIONS + +5.1. **Identity comparison**: +- `===` (identity equals) becomes `==` in Java. +- `!==` (identity not-equals) becomes `!=` in Java. +- `==` in Xtend is `.equals()`. Convert to `.equals()` or `Objects.equals()` in Java (use `Objects.equals()` when either operand could be null). + +5.2. **Null-safe navigation `?.`**: +- `obj?.method()` becomes a null check. Use one of: + - Ternary: `obj != null ? obj.method() : null` + - If-statement for complex cases + - For chained null-safe calls, nest the ternaries or use local variables: + ```java + // Xtend: resource?.URI + // Java: + final URI uri = resource != null ? resource.getURI() : null; + ``` + - IMPORTANT: If the result of `?.` is used in a comparison against null (e.g., `resource?.URI !== null`), then use: `resource != null && resource.getURI() != null` + +5.3. **Elvis operator `?:`**: +- `a ?: b` becomes `a != null ? a : b` (or `Objects.requireNonNullElse(a, b)` if appropriate). + +5.4. **`=>` operator (with/apply)**: +- `obj => [ body ]` executes `body` with `obj` as `it`, then returns `obj`. +- Convert to: + ```java + { // inline block or extract to a method + ExplicitType temp = obj; + // body, replacing `it` references with `temp` + // return temp; // if the result is used + } + ``` +- For simple cases like `new Foo() => [bar = "baz"]`, convert to: + ```java + Foo foo = new Foo(); + foo.setBar("baz"); + // use foo + ``` + +5.5. **String concatenation `+`**: Same in Java. + +5.6. **Range operator `..`**: `0..n` becomes `IntStream.rangeClosed(0, n)` or a for-loop. + +5.7. **Power operator `**`**: Use `Math.pow()`. + +### 6. LAMBDA EXPRESSIONS + +6.1. **Xtend `[...]` lambda to Java `(...) -> {...}`**: +- `[x | x.name]` becomes `(x) -> x.getName()` or `x -> x.getName()` +- `[it | name]` becomes `(it) -> it.getName()` or simply use a method reference +- `[ body ]` (no parameters, implicit `it`) becomes `(it) -> { body }` where `it` is used, or `() -> { body }` if `it` is not used. +- Single-expression lambdas do not need braces: `x -> x.getName()` +- Multi-statement lambdas need braces and explicit `return`: `(x) -> { doSomething(); return x.getName(); }` + +6.2. **Lambda with `it` as implicit parameter**: +- When a lambda uses properties/methods without a receiver, these reference the implicit `it` parameter. +- `[name]` on a `Function1` becomes `(Foo it) -> it.getName()` or `Foo::getName` +- Xtend: `checks.filter[name !== null]` becomes Java: `checks.stream().filter(c -> c.getName() != null).toList()` + +6.3. **Procedure (void lambda) vs Function (returning lambda)**: +- Xtend uses the same `[...]` syntax for both. +- In Java, determine from context whether it is `Consumer`, `Predicate`, `Function`, etc. +- For Xtext-specific cases: `Procedure1` lambdas like `[noSpace]` become `(IHiddenRegionFormatter it) -> { it.noSpace(); }` or `IHiddenRegionFormatter::noSpace`. + +### 7. DISPATCH METHODS + +This is one of the most complex Xtend features. Dispatch methods implement multiple dispatch (method selection based on runtime type of arguments). + +7.1. **Pattern**: A set of `def dispatch` methods with the same name but different parameter types: +```xtend +def dispatch void format(CheckCatalog c, IFormattableDocument doc) { ... } +def dispatch void format(Category c, IFormattableDocument doc) { ... } +def dispatch void format(EObject obj, IFormattableDocument doc) { ... } +``` + +7.2. **Conversion strategy**: Convert to individual `protected` methods prefixed with `_` (underscore) plus a public dispatcher method: + +```java +protected void _format(CheckCatalog c, IFormattableDocument doc) { ... } +protected void _format(Category c, IFormattableDocument doc) { ... } +protected void _format(EObject obj, IFormattableDocument doc) { ... } + +public void format(Object obj, IFormattableDocument doc) { + if (obj instanceof CheckCatalog c) { + _format(c, doc); + return; + } else if (obj instanceof Category c) { + _format(c, doc); + return; + } else if (obj instanceof EObject e) { + _format(e, doc); + return; + } else { + throw new IllegalArgumentException("Unhandled parameter types: " + obj); + } +} +``` + +7.3. **Important dispatch rules**: +- Order type checks from most specific to least specific. +- If a dispatch method has `override` keyword, add `@Override` to the dispatcher method, not the individual `_` methods. +- The dispatcher parameter type should be the common supertype (usually `Object` or `EObject`). +- If the parent class also has dispatch methods with the same name, the dispatcher must call `super._methodName()` for types not handled locally. +- Use Java 21 pattern matching for instanceof (`if (obj instanceof Foo f)`) in the dispatcher. + +### 8. EXTENSION METHODS + +8.1. **`@Inject extension ClassName fieldName`**: +- Convert to: `@Inject private ClassName fieldName;` +- At every call site where the extension's methods were called as `obj.extensionMethod(args)`, convert to `fieldName.extensionMethod(obj, args)`. +- If the extension field was used without a name (e.g., `@Inject extension CheckGeneratorNaming`), generate a field name following the convention: `_checkGeneratorNaming` (underscore + camelCase class name starting lowercase). + +8.2. **`extension` method parameters** (e.g., `def foo(extension IFormattableDocument document)`): +- Drop the `extension` keyword from the parameter. +- At call sites within the method body, calls that were dispatched to the extension parameter need to be converted to explicit calls: + - `prepend(checkcatalog)[noSpace]` becomes `document.prepend(checkcatalog, (IHiddenRegionFormatter it) -> it.noSpace())` + +8.3. **`static extension` imports** (e.g., `import static extension com.foo.Bar.*`): +- Convert to `import static com.foo.Bar.*;` +- At call sites: `obj.staticExtensionMethod(args)` becomes `Bar.staticExtensionMethod(obj, args)`. +- Example: `import static extension org.eclipse.xtext.GrammarUtil.*` then `grammar.simpleName` becomes `GrammarUtil.getSimpleName(grammar)`. + +8.4. **`extension` keyword on `val`/`var`** (e.g., `val extension naming = contentAssistNaming`): +- Drop `extension` keyword. Keep as a local variable. +- Convert call sites within scope to explicit calls on the variable. + +### 9. TEMPLATE EXPRESSIONS (GUILLEMETS) + +This is the MOST COMPLEX feature. Template expressions use triple single quotes and guillemets (French quotes). + +9.1. **Simple templates** (no control flow, just interpolation): +- If the template is a single line or very short, use string concatenation or `String.format()`: + ```xtend + '''{predicates.«predicate.name»(parserContext)}?=>''' + ``` + becomes: + ```java + "{predicates." + predicate.getName() + "(parserContext)}?=>" + ``` + +9.2. **Multi-line templates generating code/text**: Use `StringBuilder`: +```xtend +def compile(CheckConfiguration config) { + val properties = propertiesGenerator.convertToProperties(config); + ''' + «FOR k:properties.keySet» + «k»=«properties.get(k)» + «ENDFOR» + ''' +} +``` +becomes: +```java +public CharSequence compile(CheckConfiguration config) { + final Properties properties = propertiesGenerator.convertToProperties(config); + final StringBuilder builder = new StringBuilder(); + for (final String k : properties.keySet()) { + builder.append(k).append("=").append(properties.get(k)).append("\n"); + } + return builder; +} +``` + +9.3. **Template control flow**: +- `«IF condition»...«ENDIF»` becomes `if (condition) { builder.append(...); }` +- `«IF condition»...«ELSE»...«ENDIF»` becomes `if-else` +- `«ELSEIF condition»` becomes `else if (condition)` +- `«FOR item : collection»...«ENDFOR»` becomes `for (Type item : collection) { builder.append(...); }` +- `«FOR item : collection SEPARATOR sep»...«ENDFOR»` -- use a boolean flag or `String.join()` or `Collectors.joining()`: + ```java + builder.append(collection.stream() + .map(item -> /* expression */) + .collect(Collectors.joining(sep))); + ``` +- `«val x = expr»` inside a template is a local variable declaration. Declare it before use. + +9.4. **Template indentation**: +- Xtend templates preserve indentation relative to the insertion point. In the Java conversion, you do NOT need to replicate this Xtend-specific whitespace behavior exactly. Instead: + - For code generators producing source code: use explicit `\n` and string indentation as appropriate. + - For simple cases, inline `\n` in the StringBuilder appends. + - For complex generators, consider creating a helper method or using a `StringJoiner`. + +9.5. **Return type**: Methods returning template expressions should return `CharSequence` (to match Xtend's `StringConcatenation` return type, which implements `CharSequence`). Alternatively, return `String` if all callers use it as `String` (add `.toString()` call on the `StringBuilder`). + +9.6. **`«expression»` interpolation**: Convert `«expr»` to the corresponding Java expression inside a `.append()` call. +- `«catalog.name»` becomes `.append(catalog.getName())` +- `«IF grammar !== null»GRAMMAR_NAME,«ENDIF»` becomes: + ```java + if (grammar != null) { + builder.append("GRAMMAR_NAME,"); + } + ``` + +### 10. COLLECTION LITERALS AND OPERATIONS + +10.1. **`#[]` (list literal)**: +- `#["a", "b", "c"]` becomes `List.of("a", "b", "c")` (immutable) or `new ArrayList<>(List.of("a", "b", "c"))` (mutable). +- Empty: `#[]` becomes `List.of()` or `new ArrayList<>()`. +- `newArrayList` becomes `new ArrayList<>()` or `new ArrayList<>(...)`. +- `newArrayList("a", "b")` becomes `new ArrayList<>(List.of("a", "b"))` or `Lists.newArrayList("a", "b")` (if Google Guava is available, which it is in this project). + +10.2. **`#{}` (set literal)**: +- `#{"a", "b"}` becomes `Set.of("a", "b")` or `new HashSet<>(Set.of("a", "b"))`. +- `newHashSet` becomes `new HashSet<>()` or `Sets.newHashSet(...)`. + +10.3. **Collection operations** (Xtend extension methods on Iterable/Collection): +- `.map[expr]` becomes `.stream().map(x -> expr).toList()` or `.stream().map(x -> expr).collect(Collectors.toList())` +- `.filter[expr]` becomes `.stream().filter(x -> expr).toList()` +- `.filter(Type)` becomes `.stream().filter(Type.class::isInstance).map(Type.class::cast).toList()` OR use Guava `Iterables.filter(collection, Type.class)` +- `.exists[expr]` becomes `.stream().anyMatch(x -> expr)` +- `.forall[expr]` becomes `.stream().allMatch(x -> expr)` +- `.findFirst[expr]` becomes `.stream().filter(x -> expr).findFirst().orElse(null)` +- `.head` becomes `.get(0)` (for List) or `.iterator().next()` (for Iterable), with null safety if needed +- `.tail` becomes `.subList(1, list.size())` or `.stream().skip(1).toList()` +- `.toList` becomes `.stream().toList()` or `new ArrayList<>(iterable)` or `IterableExtensions.toList(iterable)` +- `.toSet` becomes `new HashSet<>(collection)` or `.stream().collect(Collectors.toSet())` +- `.flatten` becomes `.stream().flatMap(Collection::stream).toList()` +- `.sortBy[expr]` becomes `.stream().sorted(Comparator.comparing(x -> expr)).toList()` +- `.sort` becomes `.stream().sorted().toList()` or `Collections.sort(list)` for in-place +- `.join(',')` becomes `String.join(",", collection)` or `.stream().collect(Collectors.joining(","))` +- `.indexed` becomes use `IntStream.range(0, list.size())` with index access, or keep Guava if present +- `.reverse` becomes `Collections.reverse(new ArrayList<>(list))` or use `Lists.reverse(list)` (Guava) +- `.isEmpty` / `.empty` becomes `.isEmpty()` +- `.size` becomes `.size()` +- `.forEach[action]` becomes `.forEach(x -> action)` (Java Iterable.forEach or Stream.forEach) +- `.filterNull` becomes `.stream().filter(Objects::nonNull).toList()` + +10.4. **`isNullOrEmpty`**: +- `StringExtensions.isNullOrEmpty(s)` or `s.isNullOrEmpty` becomes `s == null || s.isEmpty()` +- Or use a utility method if the project has one. + +10.5. **`toIterable(iterator)`**: `IteratorExtensions.toIterable(resource.getAllContents())` -- keep this call as-is since it is an Xtext utility, OR convert to: `() -> resource.getAllContents()` (creating an Iterable from Iterator). + +10.6. **`Iterables.filter(iterable, Class)`**: Keep this Guava call as-is -- it is idiomatic in Eclipse/Xtext projects. + +10.7. **Operator overloading on collections**: +- `list += element` becomes `list.add(element)` +- `list += otherList` becomes `list.addAll(otherList)` +- `list -= element` becomes `list.remove(element)` +- `map.get(key)` -- same in Java (Xtend allows `map[key]` syntax which becomes `map.get(key)`) + +### 11. PROPERTY ACCESS SYNTAX + +11.1. Xtend allows property-style access for getters/setters: +- `obj.name` may mean `obj.getName()` -- convert to explicit getter call +- `obj.name = value` may mean `obj.setName(value)` -- convert to explicit setter call +- `obj.isActive` may mean `obj.isActive()` or `obj.getIsActive()` -- determine from context + +11.2. Boolean property access: +- `field.final` means `field.isFinal()` +- `field.static` means `field.isStatic()` + +11.3. **IMPORTANT**: Not all dot-access is property access. If the object actually has a public field, keep field access. Determine from the types involved. + +### 12. SWITCH EXPRESSIONS + +12.1. **Basic switch**: +```xtend +switch(x) { + case "a": doA() + case "b": doB() + default: doDefault() +} +``` +becomes Java switch expression or statement depending on context. + +12.2. **Switch with type guards**: +```xtend +switch obj { + CheckCatalog: obj.name + Category case obj.name !== null: obj.label + default: "unknown" +} +``` +becomes: +```java +if (obj instanceof CheckCatalog checkCatalog) { + return checkCatalog.getName(); +} else if (obj instanceof Category category && category.getName() != null) { + return category.getLabel(); +} else { + return "unknown"; +} +``` + +12.3. Use Java 21 pattern matching for instanceof where applicable. + +### 13. ACTIVE ANNOTATIONS + +13.1. **`@Data`**: This generates `equals()`, `hashCode()`, `toString()`, and getters for all fields (which are final). Convert to a Java `record` if the class has no mutable state and no superclass. Otherwise, manually add: +- All-args constructor +- Getter methods for each field +- `equals()`, `hashCode()`, `toString()` +- Or use `@Override` of these methods if the class extends something. + +For inner static classes annotated with `@Data` that have `val` fields and no superclass (like this project's `NoBacktrack`, `SemanticPredicate`, `GrammarAnnotations`), prefer Java records: +```java +public record SemanticPredicate(String name, String message, String grammar, List keywords) {} +``` + +13.2. **`@Accessors`**: Generates getters (and setters for `var` fields). +- `@Accessors boolean foo` generates `getFoo()` and `setFoo(boolean)`. +- `@Accessors(PUBLIC_SETTER) String bar` generates only a public setter. +- `@Accessors(PROTECTED_GETTER) Foo baz` generates only a protected getter. +- Convert by manually writing the getter/setter methods with the specified visibility. + +13.3. **`@FinalFieldsConstructor`**: Generates a constructor taking all final fields as parameters. Manually write the constructor. + +### 14. SPECIAL XTEND PATTERNS + +14.1. **`it` implicit parameter**: +- When a method declares `Type it` as its first parameter (e.g., `def generate(ExportModel it, ...)`), all unqualified method/property calls in the body refer to `it`. +- Convert: Add the parameter with a proper name (e.g., `exportModel`) and qualify all calls: + - `exports` becomes `exportModel.getExports()` + - `grammar` becomes `exportModel.getGrammar()` (if it's a property of ExportModel) + - `extension` becomes `exportModel.isExtension()` + +14.2. **`this` vs receiver**: In Xtend, method calls without a receiver may go to `this`, an extension, or `it`. You must determine which based on the type hierarchy. Check: + 1. Is it a method on the current class or its superclass? -> `this.method()` or just `method()` + 2. Is it an extension method from an `@Inject extension` field? -> `field.method(obj)` + 3. Is it a static extension method? -> `ExtClass.method(obj)` + 4. Is it on the `it` implicit receiver? -> `it.method()` using the renamed parameter + +14.3. **Multiple return statements**: Xtend methods implicitly return the last expression. You MUST add explicit `return` for ALL non-void return paths. + +14.4. **`class` keyword access**: In Xtend, `SomeClass` by itself in certain contexts refers to the class literal. In Java, use `SomeClass.class`. + +14.5. **Static method access with `::`**: `ClassName::methodName` or `ClassName::FIELD` becomes `ClassName.methodName()` or `ClassName.FIELD` in Java. + +14.6. **Pairs**: `key -> value` becomes `Pair.of(key, value)` or `Map.entry(key, value)` depending on context. + +### 15. GUICE DEPENDENCY INJECTION + +15.1. **`@Inject` fields**: Keep as-is. These are standard Guice annotations. +- `@Inject ClassName fieldName` becomes `@Inject private ClassName fieldName;` +- Add `private` visibility if not already present. +- If the field was an `extension`, see Rule 8. + +15.2. **`@Inject extension`**: See Rule 8.1. + +### 16. COMMENTS AND DOCUMENTATION + +16.1. **Preserve ALL comments**: Copy Javadoc (`/** */`), block comments (`/* */`), and line comments (`//`) exactly as they appear. + +16.2. **Copyright headers**: Keep the exact copyright header from the original file. + +16.3. **`@SuppressWarnings("all")`**: The Xtend compiler adds this. Do NOT add it to the converted Java file unless it was explicitly in the Xtend source. + +### 17. XTEND LIBRARY REPLACEMENTS + +Replace Xtend runtime library calls with Java standard library or Guava equivalents: + +| Xtend Library Call | Java Replacement | +|---|---| +| `IterableExtensions.map(iter, fn)` | `iter.stream().map(fn).toList()` | +| `IterableExtensions.filter(iter, fn)` | `iter.stream().filter(fn).toList()` | +| `IterableExtensions.toList(iter)` | `Lists.newArrayList(iter)` or stream | +| `IterableExtensions.toSet(iter)` | `Sets.newHashSet(iter)` or stream | +| `IterableExtensions.head(iter)` | `iter.iterator().next()` with null check, or `Iterables.getFirst(iter, null)` | +| `IterableExtensions.join(iter, sep)` | `String.join(sep, iter)` or `Joiner.on(sep).join(iter)` | +| `IterableExtensions.exists(iter, fn)` | `iter.stream().anyMatch(fn)` | +| `IterableExtensions.forall(iter, fn)` | `iter.stream().allMatch(fn)` | +| `IterableExtensions.findFirst(iter, fn)` | `iter.stream().filter(fn).findFirst().orElse(null)` | +| `IterableExtensions.sortBy(iter, fn)` | `iter.stream().sorted(Comparator.comparing(fn)).toList()` | +| `IterableExtensions.sort(iter)` | `iter.stream().sorted().toList()` | +| `IterableExtensions.isEmpty(iter)` | `!iter.iterator().hasNext()` or `Iterables.isEmpty(iter)` | +| `IterableExtensions.toMap(iter, keyFn, valFn)` | `iter.stream().collect(Collectors.toMap(keyFn, valFn))` | +| `IteratorExtensions.toIterable(iter)` | Keep as utility or wrap: `(Iterable) () -> iter` | +| `StringExtensions.isNullOrEmpty(s)` | `s == null \|\| s.isEmpty()` | +| `CollectionLiterals.newArrayList(...)` | `new ArrayList<>(List.of(...))` or `Lists.newArrayList(...)` | +| `CollectionLiterals.newHashSet(...)` | `new HashSet<>(Set.of(...))` or `Sets.newHashSet(...)` | +| `CollectionLiterals.newHashMap(...)` | `new HashMap<>(Map.of(...))` or `Maps.newHashMap()` | +| `ObjectExtensions.operator_doubleArrow(obj, fn)` | inline (see Rule 5.4) | +| `Functions.Function1` | `java.util.function.Function` | +| `Procedures.Procedure1` | `java.util.function.Consumer` | + +**IMPORTANT**: If the existing Java code in the project uses Guava (which this project does extensively), prefer Guava utilities over Java streams for consistency. For example, prefer `Iterables.filter(iter, Type.class)` over `iter.stream().filter(...)`. + +### 18. FORMATTING AND STYLE + +18.1. Use standard Java formatting: +- 2-space indentation (to match this project's convention) +- Opening brace on same line +- Spaces around operators +- Blank line between methods + +18.2. Keep the original method ordering from the Xtend file. + +18.3. Use `this.` qualifier only when needed for disambiguation (e.g., with injected fields sharing names with parameters). + +### 19. CHECKED EXCEPTIONS + +19.1. Xtend does not enforce checked exceptions. When converting to Java, methods that call APIs that throw checked exceptions need proper handling: +- Add `throws` declarations to the method signature, OR +- Wrap in try-catch blocks +- Check the actual APIs being called to determine which checked exceptions need handling +- Example: `CoreException` from Eclipse APIs, `IOException` from I/O operations + +--- + +## CHECKLIST + +Before returning the converted file, verify: + +- [ ] All `val` converted to `final ExplicitType` (no `var` keyword) +- [ ] All `var` converted to `ExplicitType` (no `var` keyword) +- [ ] All `def` converted to proper Java method with visibility, return type, and `return` statements +- [ ] All `override` converted to `@Override` annotation +- [ ] All `typeof(X)` converted to `X.class` +- [ ] All `===` / `!==` converted to `==` / `!=` +- [ ] All `?.` null-safe navigation converted to null checks +- [ ] All `[...]` lambdas converted to `(...) -> {...}` +- [ ] All `dispatch` methods converted to dispatcher pattern +- [ ] All `extension` methods converted to explicit calls +- [ ] All `static extension` imports converted to static calls +- [ ] All template expressions `'''...«»...'''` converted to StringBuilder +- [ ] All `«IF»/«FOR»/«SEPARATOR»` converted to Java control flow +- [ ] All `#[]` / `#{}` collection literals converted +- [ ] All `=>` operator usages converted +- [ ] All `@Data` / `@Accessors` active annotations expanded +- [ ] All property access (`.name`) converted to getter/setter calls (`.getName()`) +- [ ] All `isNullOrEmpty` and Xtend library calls replaced +- [ ] All `+=` on collections converted to `.add()` / `.addAll()` +- [ ] All `::` static access converted to `.` +- [ ] Semicolons added to all statements +- [ ] Explicit visibility modifiers on all classes, methods, fields +- [ ] All imports updated (Xtend-specific removed, Java ones added) +- [ ] All comments and Javadoc preserved +- [ ] Copyright header preserved exactly +- [ ] No `@SuppressWarnings("all")` added (unless in original source) +- [ ] Checked exceptions properly handled (throws or try-catch) +- [ ] File compiles as valid Java 21 + +--- + +## EXAMPLE CONVERSION + +### Xtend Input: +```xtend +package com.example + +import com.google.inject.Inject +import org.eclipse.emf.ecore.resource.Resource +import static org.eclipse.xtext.xbase.lib.IteratorExtensions.* +import static extension com.example.NamingExtensions.* + +class MyGenerator { + @Inject extension MyHelper helper + + override void doGenerate(Resource resource) { + val config = getConfig(resource?.URI) + for (model : toIterable(resource.allContents).filter(typeof(MyModel))) { + model.compile + } + } + + def compile(MyModel it) ''' + package «packageName»; + «IF !imports.isNullOrEmpty» + + «FOR imp : imports» + import «imp»; + «ENDFOR» + «ENDIF» + + public class «name» { + } + ''' +} +``` + +### Java Output: +```java +package com.example; + +import com.google.inject.Inject; +import org.eclipse.emf.common.util.URI; +import org.eclipse.emf.ecore.resource.Resource; +import org.eclipse.xtext.xbase.lib.IteratorExtensions; + +import com.google.common.collect.Iterables; + +public class MyGenerator { + + @Inject + private MyHelper helper; + + @Override + public void doGenerate(final Resource resource) { + final URI uri = resource != null ? resource.getURI() : null; + final MyConfig config = getConfig(uri); + for (final MyModel model : Iterables.filter(IteratorExtensions.toIterable(resource.getAllContents()), MyModel.class)) { + compile(model); + } + } + + public CharSequence compile(final MyModel model) { + final StringBuilder builder = new StringBuilder(); + builder.append("package ").append(model.getPackageName()).append(";\n"); + if (!(model.getImports() == null || model.getImports().isEmpty())) { + builder.append("\n"); + for (final String imp : model.getImports()) { + builder.append("import ").append(imp).append(";\n"); + } + } + builder.append("\n"); + builder.append("public class ").append(NamingExtensions.getName(model)).append(" {\n"); + builder.append("}\n"); + return builder; + } +} +``` + +--- + +Now convert the following Xtend file to idiomatic Java following ALL the rules above: From df92daea2f85e1739c1aef7cfb11d1b3687e1820 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jo=C3=A3o=20Dinis=20Ferreira?= Date: Sat, 28 Feb 2026 11:40:49 +0100 Subject: [PATCH 04/25] feat: migrate Batch 2+3 Xtend files to Java 21 (28 files) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Migrate 28 Xtend files across 14 modules to idiomatic Java 21.

This was essential because new modules kept appearing as CI checks expanded beyond the initial plan. +- **Suppression patterns** for rules that couldn't be fixed (dispatch method names, intentional exception catching): + - `// CHECKSTYLE:CONSTANTS-OFF` / `// CHECKSTYLE:CONSTANTS-ON` + - `// CHECKSTYLE:CHECK-OFF ` / `// CHECKSTYLE:CHECK-ON ` + - `@SuppressWarnings({"checkstyle:MethodName", "PMD.UnusedFormalParameter"})` + +## What Didn't Work + +- **Local PMD checks without `compile`** — Running `mvn checkstyle:check pmd:check` without a prior `compile` phase misses PMD rules that require type resolution (MissingOverride, UnnecessaryCast, LooseCoupling, UseCollectionIsEmpty). This caused violations to slip through local verification and only appear in CI. +- **Grepping build output with `head -30`** — When verifying with `--fail-at-end`, the first 30 lines were all `0 Checkstyle violations` messages, hiding the actual `BUILD FAILURE` at the bottom. A compilation error was missed because of this. +- **Initial scope estimation** — The plan identified 4 modules but violations existed in 10+. Each CI run surfaced new modules we hadn't checked locally. +- **Agent-generated fixes sometimes incomplete** — Agents fixed the obvious cases but missed edge cases (e.g., expanding a star import but not checking all usages, changing an import without updating all references). + +## Key Decisions & Rationale + +1. **Suppress vs fix for MethodName violations**: Dispatch methods like `_format()`, `_scope()`, `_computeTypes()` must keep underscore prefixes (Xtext dispatch pattern). Used class-level `@SuppressWarnings` rather than renaming. + +2. **CHECKSTYLE:CONSTANTS-OFF for MultipleStringLiterals**: Template-generating methods that build Java source code via StringBuilder inherently have repeated string literals. Extracting constants would hurt readability. + +3. **CHECKSTYLE:CHECK-OFF for IllegalCatch**: Some methods intentionally catch `Exception` (e.g., in code generation utilities). Suppressed rather than changed. + +4. **Switch to `mvn clean compile pmd:check` for local verification**: After discovering that PMD needs compiled classes for type-resolution rules, this became the correct local verification command. + +## Lessons Learned & Gotchas + +1. **PMD type-resolution rules need compiled code**: `MissingOverride`, `UnnecessaryCast`, `LooseCoupling`, `UseCollectionIsEmpty` all need class files. Always run `mvn clean compile pmd:check` locally, not just `pmd:check`. + +2. **Checkstyle does NOT need compilation** — it works purely on source files. + +3. **`--fail-at-end` hides early failures** — When grepping output, always check the final `BUILD SUCCESS/FAILURE` line, not just intermediate results. + +4. **Xtend dispatch methods produce underscore-prefixed Java methods** — These are a known pattern (`_methodName`) that Xtext's dispatch resolution depends on. They cannot be renamed. + +5. **CI modules are discovered incrementally** — The Maven reactor with `--fail-at-end` skips downstream modules when an upstream module fails. Fixing one module can unblock compilation of others, revealing their violations. + +6. **`ByteArrayInputStream.close()` is a no-op** — When simplifying try-finally around BAIS, safe to just remove the close call entirely. + +7. **PMD's InsufficientStringBufferDeclaration calculates actual string sizes** — A StringBuilder(512) may still trigger if the appended content totals >512 bytes. Some methods needed 2048. + +## Next Steps + +1. **Consider squashing the 4 style-fix commits** before merging to master — they're all part of the same logical change. The commits are `18fb5a34e`, `8d4d826d7`, `ab0d6df10`, `645407dd5`. + +2. **Clean up untracked `xtend-gen/` directories** — 25 untracked `xtend-gen/` directories remain from the migration. These should either be `.gitignore`d or removed. + +3. **Consider adding `mvn clean compile pmd:check` to the local dev workflow** — Document that `pmd:check` alone misses type-resolution rules. + +4. **PR is ready for review** — CI is green. The PR is #1274 on the dsl-devkit repo. + +## Key Files & Locations + +| File | Purpose | +|------|---------| +| `check.core/.../formatting2/CheckFormatter.java` | Largest single file fix (~143 violations).

    + +## Known pitfalls from the migration work + +Documented here so each reviewer doesn't have to rediscover them: + +- **`CoreException` handling** — Xtend silently wraps checked exceptions; Java doesn't. Several files needed explicit `try`/`catch` added (see commit `a5deb4e3c`). +- **PMD `UseCollectionIsEmpty`** — Xtend's `.isEmpty` translates to `.isEmpty()` but chained differently in a few places. Watch for `.size() == 0` patterns that should be `.isEmpty()`. +- **PMD `UnnecessaryBoxing`** — Xtend auto-boxes aggressively. The converter sometimes leaves `Integer.valueOf(i)` where a primitive works. +- **PMD `StringToString`**, **`UnnecessaryCast`**, **`MissingOverride`**, **`LooseCoupling`** — all hit during migration cleanup. Make sure any new violations get caught in slice review, not after merge. +- **`BasicEList` compilation errors in test code** — `XbaseGeneratorFragmentTest` needed a type-parameter fix (commit `3517ba896`). Test code that does generic-heavy collection building needs extra attention. +- **Text blocks vs. `StringBuilder`** — the later commits in this branch converted `StringBuilder`-heavy generators to text blocks / `String.format` (`da8c8d91b`, `71afbe9db`, `a5cb80dec`). Make sure any `StringBuilder` that survives is actually necessary (loop/branch). +- **`val` leaks** — Xtend's `val` always converts to `final Type`, but the converter sometimes uses a pseudo-general type. Enforce explicit types or `var`. +- **Non-parameterized SLF4J logging** — mostly cleaned up project-wide, but migration-era Xtend files had `logger.info("msg" + x)` patterns that should now be `logger.info("msg {}", x)`. + +## Rollback plan + +If a merged slice turns out to break a downstream consumer, revert the slice's merge commit (`git revert -m 1 `) and reopen the slice branch for rework. Do **not** revert files individually — each slice is one coherent unit by module. + +## Branch hygiene + +- This file lives on `feature/xtend-to-java-migration`; update the **status** column on master-merge days by pushing a commit here. +- The slice branches themselves (`migrate/xtend-to-java/`) can be deleted after merge. +- Once slice 12 ships, this branch itself is redundant — keep it around until the roadmap says all slices are ✅ merged, then delete.

(e.g. PR #1415, skill ground-truth process.) -## What We Were Working On +## Migration method (four-eyes, per module) -Resolving all PMD and Checkstyle violations introduced by the Xtend-to-Java migration on the `feature/xtend-to-java-migration` branch. The migration converted ~90 Xtend files to Java 21 across the entire dsl-devkit project, and the auto-generated Java code had widespread style violations that failed CI. +**THE SKILL:** in-repo at `.agents/skills/xtend-to-java/` (doc-driven; read+follow, NOT a Skill-tool entry). Start at `SKILL.md` → `workflow/overview.md` (Steps 0–7) → `workflow/one-file-conversion.md` → `rules/00-09` → `workflow/validation-checklist.md`. Hard rule: read BOTH the `.xtend` source AND a behavioral ground truth IN FULL before writing any Java. -The initial plan estimated ~542 violations across 12 files in 4 modules. In practice, violations were discovered iteratively across **10+ modules and 36 files**, totaling roughly 600+ violations. +**Ground truth = a FRESH build, not #1274.** For each module, build off `upstream/master` with `-T 3C` to (re)generate `xtend-gen/` — that is the authoritative, current, Java-authoritative ground truth (and the first build gate). **PR #1274** `origin/feature/xtend-to-java-migration` (complete migration, 0 `.xtend`) is the **four-eyes CROSS-CHECK** — read it and reconcile every divergence, but it may be STALE vs current master and is NEVER a substitute for fresh `xtend-gen/`. (DO NOT merge #1274 directly.) Roadmap with full per-file checklist lives on that branch: `XTEND_MIGRATION_ROADMAP.md`. + +Per-module loop: +1. `git fetch upstream` → worktree/branch `migrate/xtend-to-java/` from `upstream/master`. +2. **Build for ground truth:** `mvn -f ./ddk-parent/pom.xml -pl : -am -DskipTests -T 3C compile --batch-mode` → read the fresh `xtend-gen/` Java (authoritative) IN FULL, and the `.xtend` source IN FULL. If the class extends a generated supertype, read it under `src-gen/`. +3. **Regenerate** the Java from scratch via the skill — idiomatic, matching `xtend-gen/` behavior exactly. +4. **Four-eyes cross-check:** diff regen vs #1274's `.java`; reconcile every divergence (either side may be wrong — #1274 may be stale OR skill-non-compliant, e.g. `String.format`). +5. Vet vs validation-checklist: no `val`/`var`; idiomatic strings (literal → text block → `.formatted()` → `StringBuilder` only in control flow; NEVER `String.format`); preserved stack traces; parameterized Log4j2 (`{}`); try-with-resources; no unnecessary boxing; `@Override` everywhere; no wildcard imports; behavior preserved on non-mechanical transforms. +6.

This caused violations to slip through local verification and only appear in CI. -- **Grepping build output with `head -30`** — When verifying with `--fail-at-end`, the first 30 lines were all `0 Checkstyle violations` messages, hiding the actual `BUILD FAILURE` at the bottom. A compilation error was missed because of this. -- **Initial scope estimation** — The plan identified 4 modules but violations existed in 10+.

+
+**Sonnet×Opus migration-faithfulness experiment (DONE).** 8 workflows = 4 branches (#1426–1429) × 2 models, one model-pinned agent per file, comparing migrated `.java` vs original `.xtend` (ground truth = committed `xtend-gen`, found at `eclipse/ddk-master/git/dsl-devkit/**/xtend-gen/**`). All findings adjudicated against `xtend-gen`:
+- **ONE material finding:** **#1428 `FormatJvmModelInferrer._getDirectiveName(GroupBlock)`** — migration **silently fixed a latent Xtend bug**. Xtend `newArrayList(Iterables.filter(...))` hit the `CollectionLiterals.newArrayList(T...)` varargs trap → `ArrayList>` → `indexOf` always −1 → **always `"Group0"`** (verified `xtend-gen` L922). Migrated builds real `List` → `"Group1/2/…"`; feeds generated formatter class/method names. Caught by BOTH models. **Decision pending:** reproduce `Group0` (strict) vs keep repair + document + check downstream.
+- **Everything else:** benign idiomatic deviations (UTF-8 `getBytes`, dropped no-op `close()`, `orElseThrow`-vs-NPE), 2 trivial trailing-newline diffs (`generateSrc`, `IssueCodeValueTest`), and a pile of **whitespace FALSE POSITIVES**.
+- **Scorecard:** Opus 1 real / **2 FP** (CheckModelUtil, #1429 Javadoc); Sonnet 1 real / **~10 FP** (all whitespace). **Model agreement ≠ correctness** — both wrong on `CheckModelUtil.modelWithSeverityRange` (verified byte-identical 0/4/4). `xtend-gen` required for every call.
+- **Cost (real tokens):** Sonnet **$35.41** ($1.42/file) vs Opus **$117.99** ($4.72/file, ~3.3×). Sonnet churns on whitespace files (#1429-sonnet: $21.37, 285k out, 369 tool calls, 50 min) — advantage erodes where it's least accurate.
+- **STAGED, NOT POSTED:** the #1428 `getDirectiveName` PR comment (inline, lines 623-628, commit_id `a0e4275e989fa26415ea4e0476383cc6cdcccb5e`, attribution line included). Full `gh api` command + body in conversation. **Needs explicit per-comment approval.**
+
+**Experiment infra gotchas (reusable):** (1) `args` is NOT delivered to workflow scripts here → **bake `const CFG={...}` into the script**. (2) 8-at-once → server-side rate limit → use ≤2-in-flight throttle + sequential retry + `incomplete:[]` reporting. (3) compute file lists in main thread (agent discovery truncated to 10). Scratch scripts under `.claude/wf-*.js` + `.claude/wf-filelists.json` (untracked; clean up later).
+
+**Migration PR review status:** #1426–1429 = Ruben's CHANGES_REQUESTED are STALE (his text-block/Iterables/`{@inheritDoc}` feedback already applied & pushed) → user to request re-review. **#1430** = genuinely unaddressed (static `StringConcatenation`→text-block across ~7 Fragment2 generators; his review is on current HEAD) — deferred sweep (tasks #24/#25).
+
+**Xtend whitespace rule (settled empirically):** Xtend strips the **min content indentation** (NOT the closing-`'''` delimiter indent); Java text blocks strip min content indent too, so a correctly-placed closing `"""` matches. Migration does this right everywhere; the only real whitespace divergence is a trailing newline when `"""` sits on its own line (`}\n` vs `}`).
+
+## RESUME SNAPSHOT — 2026-06-23 (append-run → text-block coalescing; verification harness)
+
+**PR state:** **#1426 MERGED 06-23** (xtend↔java reviewed by João = ✅ OK). #1427/#1428/#1429/#1430 still OPEN. Older batch #1416–1422 merged 06-16/17.
+
+**#1428 — CI fixed.** Audit-driven extra cleanup landed: `542eb5710` (7× single-line `StringConcatenation`→`.formatted`) + `e5c9dea0c`→ rebased to `00e2743f6` (`FormatGenerator` exception `.formatted`). The middle commit `2ec9f181f` (`_elementAccess`/`_locator` `StringConcatenation`→`java.lang.StringBuilder`) **broke PMD** (`InsufficientStringBufferDeclaration` + `AppendCharacterWithChar`) → **DROPPED** via `git rebase --onto 542eb5710 2ec9f181f`, force-pushed, **CI green**. Ruben's 8 #1428 threads: **all addressed** (6 applied in original migration + `generateJavaDoc` `:412` deliberately kept — loop + two-arg indented append).
+
+**#1429 — `kwBuilder` `.formatted` pushed** (`4df925f4d`), CI green. **Ruben added NEW comments 06-23**: `:567` (`ruleImpl`), `:175` (parser ctor), more on `:90` — all the **dynamic ANTLR generators** (the risky ones).
+
+**KEY DECISION — avoid risky translations.** Removing `StringConcatenation` from the big dynamic ANTLR generators (#1429 `AnnotationAwareAntlrGrammarGenerator` 1099 ln / `…ContentAssist…` 1302 ln; 86/90 `newLineIfNotEmpty`, 43/66 two-arg appends) is **too risky / low value** (Ruben himself: "a builder is justified") → **NOT doing it**. Dedicated stacked branch idea scrapped; scratch worktree `dsl-devkit-antlr-strconcat` removed.
+
+**CURRENT INITIATIVE — coalesce consecutive append-runs → text blocks**, as a **new dedicated commit per OPEN branch** (#1427–1430; NOT amend; fast-forward push). **Scope = TARGETED** (João's pick): Ruben's flagged methods + big pure-static/single-arg runs; skip heavily-fragmented small runs.
+
+**Verification (load-bearing): executable byte-equality harness** `.claude/coalesce-verify/Probe.java` — lifts the OLD append run verbatim onto real `new StringConcatenation("\n")` vs the candidate text block `.formatted(...)`, asserts byte-equality over a battery {empty, multi-line, spaces, quotes, `%`, unicode}. Compile/run: `javac -cp  -d . Probe.java && java -cp :. Probe`. Jar = `~/.m2/repository/org/eclipse/xtext/org.eclipse.xtext.xbase.lib/2.43.0/org.eclipse.xtext.xbase.lib-2.43.0.jar`; Java 26.
+- **Empirical rules (executed, not assumed):** single-arg `append(v)` does NOT re-indent multi-line → safe `%s`. Two-arg `append(v,indent)` DOES re-indent multi-line → **exclude/split**. `newLine()`/`newLineIfNotEmpty()`→`\n`; `newLineIfNotEmpty` safe after a line with literal content, **UNSAFE after a bare value** (empty→divergence). Import-managed `append(TypeReference/Class)` → keep as separate append (split text block around it).
+- **CRITICAL:** `mvn verify`/CI do **NOT** regenerate generated artifacts (no `xtext-maven-plugin`/`mwe2` in poms; IDE-only) and there's **no CI freshness guard** → **CI cannot catch generator-output drift**. The harness is the ONLY real output gate. Committed `src-gen` is LF (line-ending check enforces) = matches `\n` modeling.
+
+**DONE so far:** **#1430 `LspBuilderIntegrationFragment2`** fully coalesced — 4 blocks (generateBuildService prologue+epilogue, generateBuildSetup imports + injector bodies), **all proven `IDENTICAL`**, **−70 net lines**, compiles (EXIT=0). **NOT committed yet** (more #1430 files under targeted scope before the single #1430 commit).
+
+**Review tracker (João confirms each xtend↔java):** #1426 ✅ OK. Pending: #1427–1430 (review AFTER coalescing lands) then older #1416–1422. **Sequence (João's order): update open PRs → review open ones → then older merged ones.**
+
+**Held comments (drafted, NOT posted — need per-comment approval + attribution; link to the coalescing commits once landed):** #1429 reply (static parts already text blocks; dynamic builders justified, kept), #1430 `LspBuilder` reply (API-bound wrapper, body now text blocks), #1428 `:412` `generateJavaDoc` note, and the staged **#1428 `getDirectiveName`** behavioural comment.
+
+**Memories added this session:** `feedback_generated_output_lf` (emit `\n` unconditionally; line-separator divergence not a blocker), `feedback_local_validation_full_checks` (pre-push must run `pmd:check`/`checkstyle:check`/`spotbugs:check`, not just `package`).
+
+**Scratch (untracked, clean up later):** `.claude/x2j-review.sh` (opens each PR's original `.xtend` vs new `.java` in `code --diff`; usage `bash .claude/x2j-review.sh `), `.claude/x2j-review//` (extracted originals), `.claude/coalesce-verify/Probe.java` (+ `.class`), earlier `.claude/wf-*.js` + `wf-filelists.json`.
+
+## RESUME SNAPSHOT — 2026-06-23 (late): APPROVALS IN → merge approved + coalescing-as-follow-ups
+
+**Ruben re-reviewed.** **#1427 APPROVED, #1428 APPROVED, #1430 APPROVED** (all `CLEAN`/`MERGEABLE`, CI 4/4 green). **#1429 = CHANGES_REQUESTED / BLOCKED** — his `:90/:112/:150/:175/:567` ANTLR multi-line-string comments; the only holdout.
+
+**Coalescing committed (harness-proven IDENTICAL, CI-gate green):**
+- **#1430** (APPROVED, includes these): `e832f558b` (LspBuilder+StandaloneBuilder+FormatterFragment2) + `5f6feaa13` (LanguageConstants). Approval survived the pushes.
+- **#1429**: `cd1d420bf` (AnnotationAwareAntlrGrammarGenerator). **ContentAssist batch-1** (imports + setters/getGrammar block) **built-green, UNCOMMITTED** in worktree `dsl-devkit-xtext-generator-parser`.
+- #1427/#1428 nothing to coalesce; #1426 merged.
+
+**Refined rule (proven):** pure-static→text block; single-arg value→`%s`; two-arg `append(v,indent)` with provably single-line value→`%s` (no-op re-indent, verify single-line battery); EXCLUDE import-managed `append(Class/TypeReference)`, multi-line values, `appendImmediate`, loop bodies. **Remainder verdict:** leftover ContentAssist/Fragment2 runs are tiny fragments inside dynamic loops/typeRef appends → low/negative value → **skip (churn).**
+
+**THE PLAN (await João's go — merging is irreversible):**
+- **Phase A — merge approved:** rebase-merge #1427 → #1428 → #1430 (`gh pr merge  --repo dsldevkit/dsl-devkit --rebase --delete-branch`), re-check `CLEAN` before each. #1430 brings its 2 approved coalescing commits. *Caveat (review-before-merge): João has NOT done his own xtend↔java review of #1427/#1428/#1430 (only #1426); merging trusts Ruben+CI — `bash .claude/x2j-review.sh ` to review first.*
+- **Phase B — #1429:** commit ContentAssist batch-1, post the held reply (static→text-blocks done; dynamic ANTLR generators kept as justified builders), request re-review → merge on approval.
+- **Phase C — follow-ups:** skip marginal coalescing; genuine follow-ups = #29 Javadoc `{@code}` + staged #1428 `getDirectiveName` comment. Scratch cleanup: `.claude/coalesce-verify/`, `.claude/x2j-review/`, `.claude/wf-*.js`.
+
+**Harnesses:** `.claude/coalesce-verify/{Probe,SB,FF,AAGG1,AAGG2,LC,CA1}.java`; xbase jar `~/.m2/.../org.eclipse.xtext.xbase.lib/2.43.0/...jar`, Java 26.
+
+## RESUME SNAPSHOT — 2026-06-23 (latest): Phase 0 review DONE → A0 bugfix split-out → ordered merge
+
+**Phase 0 ultracode pre-merge review (workflow `w8mi77f4s`) DONE.** 29 files, 8 findings, **2 confirmed / 6 refuted** (whitespace/style FPs). **All 3 approved PRs CLEAR — 0 blockers.** Both confirmed are minor + in *original migration code* (my coalescing = 0 drift):
+- #1428 `List.of(...)` in ~12 dispatcher fall-through throws (`FormatJvmModelInferrer:1434…`): NPE-on-null vs xtend-gen `Arrays.asList`→IAE; unreachable `infer(null,…)` path → optional follow-up.
+- #1427 `modelWithContexts` trailing `"\n    "`: test-helper, CI-green/harmless, whitespace-FP class → optional follow-up.
+
+**NEW DECISION (João): split the `getDirectiveName` repair into its own PR.** The migration silently fixed a latent Xtend bug (`newArrayList(filter(...))` varargs trap → `ArrayList>` → `indexOf` always −1 → every group `"Group0"`). Fix it **in the `.xtend` on a dedicated branch off `upstream/master`** so the migration stays a faithful 1:1. **This is now Phase A0, merged FIRST.** Fix = `FormatJvmModelInferrer.xtend:475` → `grammarRule.directives.filter(GroupBlock).toList` (→ `Group1/2/3`); changes generated formatter output (`Group0`→`GroupN`); open PR fork→upstream `master`, **reviewer = rubenporras**. Supersedes the old staged discussion comment.
+
+**Revised merge order: A0 → #1428 → #1427/#1430.** After A0 merges, **rebase #1428** onto bugfixed master (modify/delete on `FormatJvmModelInferrer.xtend` → keep #1428's deletion; force-push; may need Ruben re-approval) — its `.java` already emits `Group1/2/3` so it's faithful to the fixed `.xtend`. Then rebase-merge #1428/#1427/#1430 (`--rebase --delete-branch`, re-check CLEAN each).
+
+**A0 DONE (2026-06-23):** worktree `/Users/joao/Git/Avaloq/dsl-devkit-format-groupfix` (branch `fix/format-directive-group-numbering` off `upstream/master` @ `088854035`). Fix = 2 lines in `FormatJvmModelInferrer.xtend` (`.filter(GroupBlock).toList` + drop orphaned `Iterables` import). Verified: `xtend-gen` untracked + `git grep Group0` = 0 → no committed artifact affected (blast radius nil-to-cosmetic in-repo; latent bug). Full CI-gate build GREEN. Commit `c9d56d8ec`, pushed to fork. **PR [#1443](https://github.com/dsldevkit/dsl-devkit/pull/1443)** opened: draft ✓, `joaodinissf:fix/format-directive-group-numbering → dsldevkit:master`, reviewer **rubenporras** ✓. **Confirmed #1428's migrated `_getDirectiveName(GroupBlock)` already emits `Group1/2/3`** (via `Iterables.addAll(new ArrayList, filter)`) → faithful once A0 lands.
+
+## RESUME SNAPSHOT — 2026-06-25: A0+5 PRs MERGED → correctness-first faithfulness sweep running
+
+**📒 VERIFICATION LEDGER:** `.claude/migration-verification.md` — per-file byte-vet status (HARNESS / APPEND-DIFF / FAITHFULNESS / SWEEP) for every migrated file. Keep it updated as files are vetted. Bottom line: **every byte-output generator is byte-vetted**; logic/test files are faithfulness-vetted (byte-vet N/A); confirmed drifts all fixed (#1443/#1446) or benign-deferred.
+
+**#1446** (faithfulness follow-ups, draft, Ruben requested): 2 commits — `AnnotationAware` indent fix + faithful `FormatJvmModelInferrer` dispatcher throws. Ruben CHANGES_REQUESTED w/ 3 suggestions (empty-arg throws → `"Unhandled parameter types"`) → **applied + force-pushed (`e78494ffb`)**, build green. Pending: re-request Ruben / resolve 3 suggestion threads (await João).
+
+**#1429 DECISION (João):** keep `StringConcatenation` (do NOT remove per Ruben's `:90` — removal risks byte-drift), but **coalesce static append-runs into text blocks where byte-safe** (harness-gated). Sequence pending approval.
+
+**MERGED this campaign:** A0 `#1443` (getDirectiveName fix in `.xtend`), `#1428` (format), `#1427` (check-core-test), `#1444` (Ruben's CheckGenModelUtil log fix), `#1430` (generator-builder). master @ `839bfdde5`. **`#1429` (parser) is the only open migration PR** (CHANGES_REQUESTED).
+
+**Merge mechanics learned:** repo **dismisses approvals on push** (force-push re-opens review). `gh pr merge  --repo dsldevkit/dsl-devkit --rebase --delete-branch`. Rebase locally onto `upstream/master` (git cherry-pick-detection drops duplicate stacked commits, e.g. A0's commit dropped from #1428).
+
+**Per-pair review done (read-only `OK`/`not OK`):** #1427 (11 pairs → 1 nit: `CheckModelUtil.modelWithContexts` trailing `"\n    "`, harmless, disabled-caller). #1430 (12 pairs → `ResourceFactoryFragment2` verified clean; **`AnnotationAwareContentAssistFragment2` had a REAL byte-drift bug** — multi-line `Alternatives` leaf continuation-lines lost indentation: migrated single-arg `append` vs xtend-gen two-arg `append(v,"  ")`). **Fix done + harness-proven (AACA.java 7/10→10/10) + build-green; saved as `scratchpad/aaca-indent-fix.patch`** — NOT on #1430 (merged as-is); goes in the follow-up PR.
+
+### ★ GUIDING PRINCIPLE (João + Claude agreed 2026-06-25) — correctness over readability, in order
+**Generated-output BYTE-IDENTITY is the non-negotiable gate. Readability (`StringConcatenation`→text-block) conversions are a genuine good (we AGREE with Ruben's goal) but are VERIFIED FOLLOW-UPS — never unverified blockers, sequenced AFTER correctness.** Never comply with "make it a multi-line string" on sight: convert only where **harness-proven byte-identical**; keep the builder (with byte-level justification to Ruben) where folding changes output (e.g. import-managed `append(TypeReference)` cannot fold to `%s`). Three real byte-drift bugs already came from *unverified* readability conversions (`AnnotationAware`, `modelWithContexts`, `FormatJvmModelInferrer`). The sweep exists to catch exactly this.
+
+### Ordered plan
+1. **Sweep running** — `wqx01ugww` (`.claude/wf-sweep.js`): 51 Opus agents, one per merged migrated `.xtend` (excl. #1430's 12 = already harness-done), hunting byte-drift + faithfulness; adversarial verify. **WAIT for it.**
+2. **Phase 2 — harness-confirm** every `NEEDS_HARNESS`/drift file (build `AACA`/`Probe`-style harness vs `xtend-gen`); pin/fix real drift. *(`xtend-gen` ground truth lives in sibling worktrees' `xtend-gen/` dirs; `git show ^:` for originals.)*
+3. **Phase 3 — ONE follow-up PR** off master: `aaca-indent-fix.patch` + every sweep-confirmed fix, each harness-gated, for Ruben.
+4. **#1429, same discipline** — harness-verify its existing text-block conversions; address Ruben's 6 comments by converting where provably safe (harness-gated) + keeping builders with byte evidence where not; commit ContentAssist batch-1; re-request review as *"correctness-verified readability."*
+5. **Broader readability follow-ups** — LAST, only after correctness locked; separate harness-gated PRs.
+
+### #1429 — the 6 unresolved Ruben threads (all "use a multi-line string", correctness-gated)
+- `AbstractAnnotationAwareAntlrGrammarGenerator.java:90` (current): keep builder but **drop `org.eclipse.xtend2.lib.StringConcatenation`**.
+- `…Abstract…:112/:150/:180` (OUTDATED — code changed, likely already text-block'd by `b49eae6bc`): "clearly a multi-line string … and so on, I did not continue the review" (← he stopped partway, expects whole-file treatment).
+- `AnnotationAwareAntlrContentAssistGrammarGenerator.java:567` (current): would benefit from a multi-line string (ContentAssist batch-1 coalescing still UNCOMMITTED in worktree).
+- `AnnotationAwareAntlrGrammarGenerator.java:168` (current): "and this" (file coalesced in `cd1d420bf` — verify covers it).
+His steering note: *"Claude constantly forgets … multi-line strings for readability … I interject it as steering."*
+
+## Next action
+
+**WAIT for sweep `wqx01ugww` to complete.** Then: report the per-file verdict table → **Phase 2** harness-confirm flagged files → fix → **Phase 3** single follow-up PR (incl. `aaca-indent-fix.patch`). Then **#1429** per the discipline above. Deferred: #29 Javadoc `{@code}`; scratch cleanup (`.claude/coalesce-verify`,`x2j-review`,`wf-*.js`,`sweep-cfg.json`,`pre-merge-cfg.json`); #1442 draft decision; Phase-0 nits (#1427 `modelWithContexts`, #1428 `List.of`→`Arrays.asList` dead-path) → fold into Phase-3 PR. Tasks: #11 sweep (in progress), #12 harness-confirm, #13 follow-up PR.
