 Format and process
 
 - The `Unreleased` section contains completed tasks that have been removed from `TODO.md` and are targeted for the next release.
-- integration.test.task.003 — undefined — Test cleanup
-- integration.test.task.002 — undefined — Integration test completion
 - Each entry should include: task id, summary, author, PR or commit link, and a one-line description of the change.
 - When creating a release, move the entries from `Unreleased` to a new versioned section (e.g. `## [1.0.0] - 2025-09-20`) and include release notes.

+# Code Quality Standards
+
+## Architectural Rules
+
+### Index File Encapsulation
+
+**NEVER** allow index files to export from outside their directory tree.
+
+**❌ WRONG - Breaks encapsulation:**
+
+```typescript
+// src/types/rendering/index.ts
+export * from './IRenderer';
+export * from './OutputFormat';
+export { ConsoleOutputWriter } from '../../core/rendering/console-output.writer'; // ❌ BAD
+```
+
+**✅ CORRECT - Maintains encapsulation:**
+
+```typescript
+// src/types/rendering/index.ts
+export * from './IRenderer';
+export * from './OutputFormat';
+
+// Add exports to the appropriate domain index file instead:
+// src/core/rendering/index.ts
+export { ConsoleOutputWriter } from './console-output.writer';
+```
+
+**Rationale:**
+
+- Maintains clear module boundaries and encapsulation
+- Prevents circular dependencies
+- Makes dependencies explicit and traceable
+- Follows domain-driven design principles
+- Improves maintainability and refactoring safety
+
+**Enforcement:**
+
+- Code reviews must flag any index file reaching outside its directory
+- Automated linting rules should be added to prevent this pattern
+- Refactoring should move cross-domain exports to appropriate domain boundaries
