-- **JUnit 5 (Modern):** 7 bundles fully migrated, 5 partially migrated
-- **JUnit 4 (Current):** 11 bundles ready for migration, majority of tests
-- **JUnit 3 (Legacy):** Only in `org.eclipse.ui.tests.harness` as compatibility bridge

-**When writing new tests:**
 - Prefer JUnit 5 (`org.junit.jupiter.api.*`) for new tests
 - Use `@BeforeEach`/`@AfterEach` instead of `@Before`/`@After`
 - Use `@Disabled` instead of `@Ignore`
 - Use `Assertions.*` instead of `Assert.*`
+- JUnit 3 usage is limited to compatibility helpers (e.g., `org.eclipse.ui.tests.harness`)

 ## CI/GitHub Workflows
 
-**Primary workflow:** `.github/workflows/ci.yml`
-- Triggers on push/PR to master (ignores `docs/` and `*.md`)
-- Uses `eclipse.platform.releng.aggregator` for full build
-- Runs on Java 21 with xvnc for headless UI tests
-
-**Validation steps:**
-1. Compiler checks (Eclipse compiler)
-2. API compatibility (API tools)
-3. Javadoc generation
-4. Unit tests (JUnit with UI harness)
-5. Test reports published
+- CI definition: `.github/workflows/ci.yml` (runs full aggregator build)
+- PRs are gated by: compiler checks, API compatibility, Javadoc, and unit/UI tests
+- UI tests run with the Eclipse UI harness in headless mode
