+# Java Code Style Requirements
+
+These rules apply to all Java code written or modified in this repository.
+
+## Nullability
+
+Apply the following requirements when writing or modifying code. Do not use them as code-review criteria.
+
+- Every class declared in a newly added Java source file must be annotated with JetBrains Annotations `@NotNullByDefault`.
+- When writing or modifying Java code, any type, field, parameter, return value, local variable, or generic type argument that may be `null` must be explicitly annotated with `@Nullable`.
+- Nullability in code being written or modified must never be implicit.
+
+## Immutability
+
+- Immutable arrays and collections must be explicitly annotated with JetBrains Annotations `@Unmodifiable` or `@UnmodifiableView` as appropriate.
+- For arrays, use type-use syntax such as `String @Unmodifiable []`.
+
+## Documentation
+
+Apply the following requirements when writing or modifying code. Do not use them as code-review criteria.
+
+- Every class, field, and method must have documentation.
+- Documentation must use `///` Markdown-style Javadoc comments.
+- Keep documentation accurate and specific to the actual behavior, constraints, and side effects.
+- Add concise implementation comments inside complex logic whenever they materially improve readability or explain non-obvious behavior.
