- Add @Schema(requiredMode = REQUIRED) to SkippedFile and ImportStatus
record components so TypeScript codegen produces non-optional fields
when generate:api is next run
- Extract openFileStream(File) as package-private method so the
IOException path can be tested deterministically without relying on
OS-level file permissions (which are bypassed when running as root)
- Replace assumeTrue-based IOException test with Mockito spy that stubs
openFileStream — test now runs in CI unconditionally (45 tests, 0 skipped)
